American intervention in and post WWII Essay

Every society, religion and ethnicity always has within it capability for extreme violence. This is often manifested in the culture to consider other fractions of the society as inferior and go ahead with acts to exterminate or kill them.   This scenario is accelerated to greater heights when the faction considered remain silent even when their rights are violated. Benito Mussolini, the II Duce, was an avid writer and later became a journalist with the Milan socialist paper ‘Avanti’ He was famous amongst the supporters of a socialist idea and then began promoting his views on the support of war against Germany in World War I. After joining politics for sometime,  Ã‚   Mussolini went back to journalism as a career on which he spearheaded and promoted his ideas against Germany. This led to the birth of fascist party on March 23rd 1919 immediately after the end of World War I. The destruction and loss of lives led to the popularity of the National Fascist Party since many were disenchanted the leadership following the after effects of the war. Mussolini stood on time and seemed to offer solutions to the Italy’s ailing economy and bring back the lost glory after the World War I. The Roman Salute and the Black Shirt Militia which were later copied by Hitler were his creation. He was elected to the Italian Chamber of Deputies on March 15th, 1921. This provided more confidence and boost to his political ambitions. Several factors worked on Mussolini‘s favor in his rise to power. In August 1922, the ruling Leftist Party called for a nationwide strike. Mussolini saw this as an act that would destabilize the state and ordered the leftists to call off the strike or his Fascist Party would. King Vittorio Emmanuelle III saw the capability of Mussolini in handling the affairs of the nation and invited him to travel to Rome and form the government. Mussolini did not accept the invitation and instead insisted on a telegraph and soon it was wired. The desire by France to take control of mineral rich Ruhr Valley saw it take sides with Italy on the Conference of Ambassadors and this bolstered Italy’s position since most of its endorsements were accepted.   The government of Greek had nothing else to do and sensing defeat gave in to Italy’s demands thereby adding more confidence to Mussolini. The thirst for more power and expansionist ideas led Mussolini to annex the city of Fiume from Yugoslavia, a successful operation that earned him a British Knight of the Bath. He was unsatisfied with the treatment Italy was accorded for giving the necessary assistance in defeating the Germans in the World War I. His thirst for power never ended and he dreamt of the day the Mediterranean Sea would be under his control. Italy then invaded Ethiopia under Mussolini‘s commands as a revenge against their shameful defeat at the battle of Adwa in 1896. Such expansionist ideas led to Italy’s blacklisting by the League of Nations and as such forged a new close relationship with the Nazi Germany that harbored the same ideas. The League of Nations lacked the political mandate to reign on rogue nations such as Italy and Germany and Mussolini realizing this, continued with his expansionist ideas .Mussolini invaded Albania in 1939 and fully strengthened its alliance with Germany by forming the Pact of Steel.   His exploits in war were always unsuccessful and due to lack of organized military techniques, lost many of the regions it had annexed earlier. By 1943 Italy’s role in the war had seriously deteriorated and Mussolini was headed to a big loss in the war. Mussolini developed the culture of dismissing the king commands and made him a ceremonial leader. In July 1943, Mussolini met his end onto the hold on power. He was arrested and deposed by elements within the ranks of his own Fascist National Party and the King appointed Field Marshal Pietro Badoglio as the New Prime Minister. He was arrested but saved by Hitler who still regarded him as strong ally in the war. He made many unsuccessful attempts to return to power by forming the Italian Socialist Republic in regions that were under German control, imposing himself as the leader. Mussolini was finally arrested by on April 28, 1945 with his mistress Clara Petacci, this time by Italian forces near Lake Como. He remained under Italian custody but realizing that he was going to be killed ordered that he be shot immediately. His long time friend, Walter Audisio eventually shot him in his chest on Mussolini’s request.   American Intervention in and Post World War II The overall American intervention in World War II was as a result of the surprise   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  attack of Pearl Harbor the Japanese army and the Franklin D Roosevelt fear of an imminent attack of North America by the Germans. The allied forces continuously bombed the allied strongholds and military bases including the German and Japanese cities of Dresden and Tokyo respectively (Jackson and Gleave, pp 87-103). This was based on the belief that killing and destroying civilian areas would discourage more civilians in supporting the war and also put more pressure on their governments to bring an end to the war. While this idea was geared towards ending the war faster, it in turn brought about the opposite. Civilian support for their leaders and the war increased and the war took longer than was previously thought causing many deaths and further destruction of property. Another intention of America on intervening in World War II was done in the name of freedom and democracy to the oppressed.   It is true that freedom and democracy form fundamentals of human rights but these interventions have left behind more sufferings manifested in the loss of lives and the destruction of property. This is because it is always difficult to make a distinction between rebels or armed groups and civilians. Italy was the first of the axis to experience the nature of America’s military intervention when President Roosevelt, Prime Minister Churchill, and the combined Joint Chiefs of Staff decided to make the first island of Sicily their first target. According to the U.S. Army Center for Military History (para. 2), the allied forces conquered Messina, the capital Sicily on 17 August 1943, a feat that propelled the Allied forces to push forward with their agenda of freeing Europe of Nazi and fascist idea. The support in terms of humanitarian and relief services from the United States did not begin after the war but in fact began long before the war. This demanded full control of organizations and relief services. During the war, relief services to the Axis –countries was not permitted as in the case of world war I. President Franklin D. Roosevelt saw this as providing further support to German and its allies .This condition continued for long even after the entry of the United States into the war in support of the allied forces. 1939 Neutrality Legislation demanded whole openness and full background details regarding relief agencies as some organizations could be sympathetic to the warring factions. In 1941, Joseph E Davis took over as the head of war relief agencies and brought in much needed reforms that included reducing the number of licensed relief organization from 300 to only 67 by the end of the war immediately after the war the relief control board formally known as the war relief agencies took over the advisory role on voluntary foreign aid. The relief services provided by the American government in World War I had many differences with that of world II, these included regulations regarding the provision of relief services to the prisoners of war and the additional statute on the Geneva Convention regarding the role of the Red Cross. All countries that took part in World War II with exception of Japan and the Soviet Union, were signatory to the 1929 Geneva Convention regarding the overall treatment of prisoners of war. Relief suppliers that included clothing toiletries and medicine were taken to prisoners in the prisons. Continuous inspections by the international Red Cross made sure that term of the Geneva Convention were fully complied with and all prisoners of war receive humane and fair treatment. Due to the different standards for treatments of war prisoners, the Geneva Convention strived to achieve an even state of treatment. Prisoners of war from countries that were not signatories to the Geneva Convention were badly treated by the Geneva Authorities. The overall performance of the Italians in World War II has had different opinions on whether it was a success or a failure.   The general idea that the  Ã‚   Italians military gave a poor show of there strength and surrendered early is not very true.   There are standing examples in very successful war exploits that Italian military achieved Italian military poor ratings from the world war11 seemed too have cropped up due to failed annexing of Greek Island and the unsuccessful take over of North Africa. Describing Italian soldiers as numerous were other factors that definitely contributed to such military mistakes.   Lack of modern weapon, poor leadership and division amongst the rank of Mussolini’s senior advisors that led to lack of will in the objective to accomplish his major war exploits. In 1939, Germany invaded Poland and took control of it; Italy at this point was not in a military position to launch and offensive. Hitler and Mussolini both wanted a redrawing of Europe’s map and in harboring this kind of vision; Mussolini ignored the state of Italy’s military strength and the inability of its war industrial complex to produce modern weapons that were capable of  Ã‚   sustaining a full scale war. Other neighboring nation such as Britain, Germany and France had put a lot in the development and   production of military weapons and had supplicated tanks, guns ammunition and trucks at there disposal(Evan, pp 743-756). In fact at the time of joining the Second World War, Italy’s position in terms of equipment was only at the same level with the First World War.   Ã‚  Ã‚  Ã‚  Its war artillery included the remnants from the First World War that were in ineffective and outdated. It lacked industrial capacity to produce new military equipment and those that were made were always out numbered by the demand. Beretta Pistols and automatic rifles were considered very efficient war machines but were always short in supply while the dreaded machine and sub standard qualities. The shipyard at their disposal was properly designed but lacked the strength in armor and lacked radar. This made it difficult for the Italy military to perform effective in comparison to other nations. Mussolini invented the art of propaganda and as such projected an image of effective air power but was in reality non existent. The whole military had only a few thousands of air crafts, most of which were bi-plane. The modern creations were of no match to those in the possession of the Allied forces. The command of Italy at the beginning of World War II was considered the poorest of all the nations that took active military exploits. Mussolini depended on loyalty as the main basis of selecting officers in various military ranks at the expense of experience. In fact Italy had the least number of experienced generals by the time of joining the war. The commanders and generals who had taken part in World War I were considered as sympathetic to the King and as such were taken to Africa and specifically in Somalia to do away with opposition in homeland. Other tactics involved the demotion of officers who were loyal to the King to lower ranks and replacing them with those that were considered loyal to the II duce. Mussolini asserted full control of the media and all organs of the state and those who criticized him were exiled in the wastelands of Italy such as Somalia. The remainder was composed of loyal military commanders and generals who were loyal to Mussolini and acted as his own stooges. This consisted of a class in the military that lacked the experience to handle a full scale war. Italy’s navy had very limited number of ships that were capable of defending its territorial waters (Gregory, pp 86-99). Poor leadership in the military and the lack of will to fully implement Mussolini’s objectives were main contributors to Italy’s unsuccessful conquests. Italy could not come out the war victorious. The Italian command sensing loss after the Axis evacuated their strongholds in Italy such as the Island of Sicily and the loss of Messina (Atkinson, pp 201-220). The high army command then opened secret negotiations with the Allied forces behind Mussolini’s back with the full support of the King who felt betrayed by Mussolini and undermined his position. He in fact blamed Mussolini on political problems that befell Italy. This almost marked the end of Italy’s active military involvement in the war. The unrelenting Germans disarmed Italian soldiers and rushed in to take up their positions upon realizing that they were about to surrender to the Allied forces.   Conclusion In conclusion, it is obvious that Italian military under the command of Mussolini was headed to a big failure in the war as they got involved into a war the least prepared for and lack of political will to fight Mussolini’s personal war. The whole military at that time lacked both the material and human resource and everything was undertaken to please Mussolini’s desire to gain a greater control of Europe. Questions as to why Mussolini’s would drive an ill equipped army into a full scale war remain baffling to date. The terming of Italian soldiers as cowards was utterly baseless as they fought so well under the experienced guidance of German soldiers led to defeat in Greece and the continuous successful offensive along the Russian borders. It was therefore a multiple number of factors that led to Italy’s early surrender but not cowardice. Mussolini’s inability to learn and change tactics was the major contributor to the progressive loss of war. Lastly it can be said that Italy bravely fought and lost.

How to Become a Successful Entrepreneur

Table of Contents Introduction Generally people think that an entrepreneur is a visionary, somebody with great ideas who is eager to take huge risks. However having a radical innovation from the nothing is overwhelming but very rare. To be successful, it is essential to think differently from the casual thinkers. The aim of this paper is to show how we, a study group of five students could come up with an idea in an entrepreneurial way and go through an elaboration process toward the realization using the theoretical frameworks.In the first part I will describe how my group went through the idea generating process and found the idea of the CPH Bike SOS with the help of the Design Thinking Method. Our multilateral service invention has three pillars, each of them with the aim to answer the question: Where can we get help if we have any problem with our bike when the shops are closed? Living in Copenhagen, we have realized that there is a market gap on the service market of the bike sh ops. On the other hand, looking at the market segment, we are sure, that there is an unsatisfied need.The second part of the paper will focus on the theoretical framework of the dea. I will define the type of our innovation, after which I will decide about the type of the firm we should start to realize the idea, and then the focus will move to the needed resources and collaborations we need to get the idea off to the market. At the end of my work, I will take a glance on what kind of the type of possibilities we have to be successful in the future and how to develop the idea further. Generating ideas In this chapter I would like to describe our process of generating the idea.It is a really important part of the task we were working on, since it explains how our group ent through a progress from the casual reasoning to the effectual reasoning and so thinking on a more entrepreneurial way. In my team we are five girls, each of us are foreigners here in Denmark, and we have quite diff erent backgrounds. We had some difficulties to find a creative idea to work on. On one hand the problem was the fact that we did not know each other before, so there was an initial phase of trust- building. We had to familiarize with the situation to debate on each other's ideas.On the other hand, we realised that when we had an idea which was a direct solution to ome problems and so Just the final step of an entire process. So we started the process again and again to get back to thinking â€Å"out of the box†. As point of departure we used the method implemented by IDEO. (Figure 1) : Figure : Design Thinking Model of IDEO (Source of Image) Inspiration – What is the problem? In the inspiration phase, we wanted to find as many ideas as we could, to have a wider range. As mentioned, we did not know each other, and we did not know what could be the common interests, experience or problems.We used the â€Å"Bird In The Hand† Principle to look into the facts what we have right there. As Sarasvathy sums it up, instead of having one solution and finding the way to reach it, we should take a step back and define the means which can lead us to a good opportunity. So the first step was defining the framework in which we are searching for possibilities with the following three questions: â€Å"Who are we? † We started to look through the features which describe us and so along which we can find some problems we all have in common.As long as we are all foreigners, our biggest issues are around living without the familiar things that we were surrounded by every day and getting used to a new way of living. We live here without our families, we had to arrange housing for ourselves, we are getting accustomed to biking every day. On the other hand we are students, spending time on studying, we all have a limited budget, then we are all girls who love fashion, we cook for ourselves, do groceries, we listen to music and go out, etc. Without knowing e ach other we succeeded to find numerous common topics as a good initial. What do we We study together but our previous education is different. One part of the group studied international business so that part of the group has a more business riented point of view, while the other part of the group has a more design oriented education. Most of us have lived in different countries other than our home country, so we have insight to different systems. We also have working experience that helped us in having an insight of the companies. â€Å"Whom do we know? † With this question, as Sarasvathy suggests, we have to define the sources of our knowledge, such as our social and professional networks.When an issue was considered, we defined the relative groups we can have any information from. It is important to take any stakeholder into consideration, as long as good ideas can come rom the most unexpected sources. With all these given means we defined some of the problems, interests a nd difficulties that we are currently facing in common. In the framework of's model of Entrepreneurial Thinking – Effectual Reasoning, we defined different issues on the basis of the given means described above, for which there is no satisfying solution on the market.On Figure 2 1 would like to provide some examples to our process of using the method of the â€Å"Bird in the Hand† Principle. Figure : Entrepreneurial thinking – Pool of ideas (Source: Sarasvathy, 2001) At this oint of the idea generation we had to choose one among the several given. To choose one, we started brainstorming whether we have any idea for a solution or not. So this is the second big step of the idea creation in the Design Thinking Model. Ideation – â€Å"How might we solve the problem? As long as we did not want to limit ourselves, we started to search for solution for many problems we have found. From the most unusual till the most ordinary idea, we collected everything, becau se even bad ideas can be the source of some really good solutions. On Figure 3 1 snow some imagined ends ot the problems. Figure : Using Entrepreneurial Thinking – Effectual Reasoning for creating the idea (source of image: Sarasvathy, 2001) Finally we sticked to the idea of finding a solution to an everyday problem: Where can we get help if we have any problem with our bike, when the bike shops are closed?We found this problem interesting as long as we all have bikes, and some of us have already experienced how it is when you need some help and nothing is open. Moreover, biking concerns not only us but the major part of the habitants of Copenhagen. According to the Bicycle Account 2012, 75 % of Copenhageners use their bike throughout the year. Another surprising statistics is that 36 % of everyone who studies or works here uses the bike every day. So with a solution to the question above, we can say, that we would reach the major part of the Danish capital.Biking has statist ically measured benefits both for us and for the environment. For instance, as the research shows, at present rate 90,000 T of C02 per year saved by cycling in Copenhagen. Then, according to the 56% of the Copenhageners, it is faster than any other way of travelling since we do not stuck in a traffic Jam and we can easily find short-cuts. It is definitely healthier too. But it can cause some inconvenience as well as delays respecting to our schedule, in case of problems. For example what if you get a puncture going back home by night?

A Raisin in the Sun & the American Dream

The American dream in the ’50s was close to materialism. The ownership of consumer goods was believed to bring joy into a family’s life. This stereotypical view governs the dream of one of the main characters in Lorraine Hansberry’s play.The title of the play is based on â€Å"Harlem† by Langston Hughes, a poem that raises a question about a dream that is deferred. â€Å"Does it dry up like a raisin in the sun? †¦ Or does it explode?† (Rampersad, 1995, pg. 426) There are three main characters and all three of them of have dreams that have been prolonged for too long. A Raisin in the Sun is about the rocky journey they go through to acquire their dreams.  The Younger’s family has just received a $10,000 dollar check for their dead father’s life insurance policy. They live in a two bedroom apartment on the black side of town in Chicago. Racial prejudices against blacks in that era and a low income are the root of conflict in the f amily.Mama, deceased Mr. Youngers widow wishes to buy a house and fulfill the dream she once saw with her husband. Beneatha, Mama’s daughter, hopes to find her identity through looking towards true African heritage. Walter, Mama’s son, wishes to one day become rich. He wants to replenish his marriage and provide his son with all the opportunities he never had growing up.Walter wants to invest money in the liquor business with a few of his friends. Although the idea appalls Mama at first, she trusts and supports her son with his decision. The night before making the investment Walter tells his son about the business transaction he about to make while tucking him into bed. He tells the little boy that their lives will change soon and paints an elaborate and vivid picture of the future. He tells his son that when he’s seventeen years old he’ll come home and park the Chrysler in the driveway.The gardener will greet him and when he’s inside the house he ’ll kiss his wife and come up to his sons room to see him browsing through brochures of the best colleges in America. He then tells his son that he will give him whatever he wants. Although Walter is somewhat materialistic in what he wants at the core he just wants a happy family and a son who should have all the chances he never had.During this time Mama buys a house to fulfill the dream she saw with her husband; the only one she can afford is in a white suburban neighborhood. Mr. Lindner a man from the neighborhood comes to the Younger house trying to convince them to not destroy the white community. He offers a lot of money in exchange for their acceptance.Meanwhile Walter looses all the money he has invested in the liquor store because I friend has run away with it. When he looses the majority of their financial resources the entire family falls into a deeper level of depression. At this time, Walter decides to take the money the white man has to offer. The thought of sel ling away their right vexes Mama, Walter’s sister and his wife. They detest Walter for dealing with his dead fathers money so easily and feel that he has lost his soul when he days we wants to be bought out by the white Mr. Lindner.Ultimately, loosing everything they have unites them because at the last moment Walter changes his mind about taking money from Mr. Lindner. Walter tells him that they have moved into the house because their father earned it for them. He continues by saying that they don’t want to disturb the neighborhood peace or protest for bigger causes, and that they’d be nice neighbors.He tells Mr. Lindner that he doesn’t want the money. At this moment the entire family’s spirits are lifted and they are proud of the decision Walter has made. This act of standing by your family to achieve the American dream of succeeding no matter who you are and where you come from unites them. They learn to support each other and put their families before their own. By owning a house, having a high morale, and the support of their family, each of them is on their way to fulfill their American dream.ReferencesFoulis, Rhona (2005, March, 14). A Raisin in the Sun.

CIS - Essay Example C++ is an extension of the C programming language. It is a high level third-generation programming language that was originally designed for UNIX systems. The term â€Å"C++† was coined in 1983. C is another programming language that was developed by Dennis M. Ritchie in the 1970s at Bell Labs (Codingunit.com, n.d). Bjarne Stroustrup had worked with Simula, the first object-oriented programming language. The idea of creating C++ arose from a need for features that were not possible with other languages at that time. He added object oriented features borrowed from Simula into C to create a new programming language that was fast, efficient and easier to design. C++ is currently used in desktop applications, telecommunication systems, data analysis, simulation, manufacturing systems, clinical systems, irrigation control systems, web applications, graphics design, desktop and mobile operating systems amongst other uses (Stroustrup.com, 2015). iv) Lines four and six have opening and closing braces. These braces indicate the beginning and end of the int main() function definition. The content inside the braces is the actual code that will be executed when this function is called by the program. v) The fifth line is a statement.

It is a golden necklace whose value indicates that it was a treasure that has to be passed-on the family line, an indication that the family relationship is valued and treasured. The leather wallet given to me by my uncle during my 12th birthday remains another valued artifact for me. The wallet has my names inscribed on it, and it is made up of pure leather. My uncle ordered it as a birthday gift for me when I was turning 12 years old, and it has remained the favorite of all my possessions, more so because it has my name on it. The significance of this artifact is that it gives me my identity, my name. Whenever I have the wallet with me, I feel that I have something that identifies with me, with my name. It signifies that presents and gifts can make a real impact on the life of an individual. The photograph of me, my sister and our friends at the train station when we were young, is another artifact that I value. The photograph was taken when we were young, during our migration journey to our new home. It was taken when my sister was crying at the train station, when we were waiting to board a train, because she did not like the idea of moving from our previous residence to our new home. She was sad, since she was leaving all her friends behind, and we were trying to console her. The significance of this artifact is that it reminds me of our childhood, when were so close with my sister. It brings back the beautiful memories of our life in our previous residence, where we lived closely with our neighbors since the residences were not spacious, and all families integrated as though they were one big family. It is an artifact signifying social integration that is rarely possible these days. My friend gave me a painting when I was graduating from high school, which has always reminded me of our friendship. Many

Giant impact theory Assignment Example | Topics and Well Written Essays - 250 words

Giant impact theory - Assignment Example Grains of dust collided and formed bigger objects known as planetesimals. During collisions, many planetesimals break up during collision but the larger ones survive and become protoplanets and later planets. If these planetesimals had remained stationary, the solar system would be made of thousands of small objects such as planetesimals without any planets. Life would have been possible in small objects. Alternatively, planets would have been small. The third scenario is solar system would have formed. Larger planets have more internal heat to lose compared to smaller planets. In addition, there is proportionally smaller surface area to lose the heat from. The larger the planet, the bigger the less the surface are per unit volume. Small worlds or planets cool faster than the big world. When the planets completely cool off, they become geologically dead (Seeds, Michael and Backman 15). Planet earth is yet to cool of completely and this means it is geologically active. Activities taking place at the core of the earth are responsible for volcanism, movement of tectonic plates, cratering and others. Bigger plants are more geologically active. If rotation is faster, geologic activities

Euthanasia is Morally Incorrect Essay Example | Topics and Well Written Essays - 2500 words

Euthanasia is Morally Incorrect - Essay Example It is morally incorrect because it allows one human to take away the life of another; an act that should be frowned upon (Narbekovas & Meilius 2004, p.2). All human beings have to die a natural death and there should be no excuse to take the life of an individual to alleviate pain and suffering because, in the modern world, strong painkillers have been developed to ensure that pain is significantly reduced among patients. However, putting euthanasia into practice presents a moral dilemma for those medical practitioners who preside over it because it is a contravention of the Hippocratic Oath, which they take as a guarantee that they will be dedicated to preserving human life. Therefore, while the advocates for euthanasia state that it helps to end suffering, it is also a violation of the basic principles of life that have sustained societies for ages. In this paper, there will be a discussion of the ramifications of euthanasia on the society, the principles that make it a moral issue, as well as its impact on the individuals who take part in it. The discussion will be based on recent years, where euthanasia has been conducted as a means of removing the financial burden from medical expenses from families. In addition, in some cases, it has been done in direct violation of the wishes of patients and this has made euthanasia something akin to murder rather than as a means of ending the suffering of patients. Euthanasia is an act that is immoral because it goes against all the principles of life as dictated by religion; where the right to take away life belongs only to God rather than to human beings. Moreover, when euthanasia is conducted, there is often a failure to consider the emotional toll that it might take on the families of the patients because not only  might they feel guilty and be full of regret for allowing it to happ en, but it might lead to some of them falling into depression.

Due to the uniqueness and stability of the building, the Colosseum has influence the modern architecture in almost all aspects. Modern stadiums are using the Colosseum architectural design to ensure that the stadiums are strong enough to accommodate the maximum number of spectators. The structure of the Colosseum was unlike other Greek theatres built into the hillsides, as it was wholly a freestanding structure (Croci 1996). The outer wall is assumed to have used a thousand cubic meters of travertine set without mortar. For this reason, they were held together by three hundred tons of iron clamps.

The Face of Battle - Essay Example I’ve been through two wars and I know. I’ve seen cities and homes in ashes. I’ve seen thousands of men lying on the ground, their dead faces looking up at the skies. I tell you, war is Hell! General Sherman had seen war up close and his admonition rings horribly true, and bears the ring of truthfulness gained through his heart experiences. However, the knowledge of the actual experience of war that most people have gained is most likely through secondhand exposure by way of literature or newspaper accounts or military histories. In his book â€Å"The Face of Battle" John Keegan, a respected military historian and lecturer on war at the Royal military Academy at Sandhurst, attempts to put a human face upon the experience of war in ways perhaps never attempted before. The purpose of his book is to describe experience of war, the most extreme of all human experiences, for those who have not experienced it firsthand. Paradoxically, Keegan himself is strictly in an academic who has had no personal experience of war himself, but only knows it secondhand through readings and personal information gained from relatives. Keegan points out in the poignant and illuminating introduction to the books main thesis that the writing of history there has been a paucity of descriptions of war which can give to a reader any sort of realistic and visceral understanding of the process and all of its horrible mechanisms. In his overview of the worlds literature on war he shows that almost all writings on the subject can be pigeonholed into a number of distinct categories. They can either be described as poetic and imagistic, desiccated and academic, wholly inaccurate and useless for gaining understanding, vague and confusing, too temporal, local and subjective, and perhaps worst of all of a self-serving. For a prime example of the poetic and imagistic style of the war literature the author provides a spectacular example written by General Sir William Napier concerning a

The report deals with a small US based Telecom Company and its application of operation management practices backed with diverse theoretical frameworks of operation management (discussed in the theoretical framework section). The company in application is basically a provider of telecom manufacturing services to various small scale technology companies. The company has employee strength varying between 30 and 35 and is situated in the United States of America. The areas of specialization of the company are circuit cards manufacturing, system level assemblies and precision sheet metal. The company also receives funds from a big telecom company which provides products like metal chassis and assemblies. Coming to the development pattern of the company, the revenues of the company in the fourth quarter of the year 2012 increased by a small percentage compared to the fourth quarter of the fiscal year in 2011 but the net income of the company declined significantly as compared to the previous year. The growth of the company taxed the current operational processes and a necessity for an automated solution was necessary for the purpose of processing as well as analyzing the telecom invoices. There was also an increase in the number of employees by the company for meeting the demands of the customers and also there were escalations in the number of services being purchased by the employees of the company. The cost per employee also increased because the employees used cell phones, pagers and other electronic gadgets without proper oversight. There was also increase in the costs of internet access for the telecommuters. An urge for Total Quality Management procedure was highly felt. There was development in the information techn ology database along with the advancement in the tools. But the development in the IT tools was not properly engaged in streamlining the billing procedure of the company. Data collection in the United States is more or less straightforward but there is a great difference in the billing processes among various countries as various countries using different ledgers and various global solutions and also with respect to the knowledge of global currencies. Variations in vendor commercial performances added layers of intricacies to the billing organization chore. It can be stated that the company’s financial strength is declining a bit but the company also has a potential market presence and directs towards maintaining a strong position for itself. 2. Outline of the purpose of the study The company encountered a bad phase of revenue decline from year 2004 to 2007 during which it served some of the big companies in the telecom industry as its client. The problem was that these were all high volume but low margin accounts and pricing pressure adversely affected the company’s profit portfolio. After that it moved into the domain of military and aerospace industry which escalated the company’s growth to a certain level. But the military and the

The Milestones and Major Developments in the Early Paleozoic Era Essay Understanding the diversity and complexity of life as observed in the current modern days may seem as difficult as defining life itself. The changes, developments, and evolution of the earth and the life forms it holds are all varied and sundry enough which makes it hard to understand without looking back to when, where, and how it all started. History, Geology, Paleontology, and many other branches of Science play a significant role in aiding people to better understand the roots and beginnings of the life seen today. These fields of studies help and serve like windows to the past which make it easier to know what it was like back when the Earth was young and life was primitive. These various disciplines draw attention to where life originated. Knowing the evolution of the earth and life forms can help make people understand what the modern life is made of. While some would see this study as a lame and monotonous venture, it can never be denied that knowledge about the origins of life and the world addresses very common issues like confusions as to how the modern human beings got their form and the very controversial issue as to where actually life came from. Debates and ideological arguments will always be inevitable, but Science got the only factual proofs and pieces of evidence about where life actually started and how it came to its present form from the simplest and most primitive elements. All these can only be understood by studying and looking back at the beginning. Thus, this paper shall discuss one of the most important and most highlighted eras in the history of life and the Earth—the Early Paleozoic Era. The Paleozoic Era The term â€Å"Paleozoic Era† literally equates to the term â€Å"time of ancient life† (Farabee). This is the bracket of time between 544 and 245 million years in the past. The Online Biology Book written by Michael Farabee and sponsored by Estrella Mountain Community College summarizes the major highlights of the Paleozoic Era. A section of the book explains meticulously about this prehistoric period. The Paleozoic era is from the general period when life forms began to spring known as the Phanerozoic Eon. This period has been known to exist about 542 million years ago (Farabee). Phanerozoic Eon consists of three specific eras such as: 1) Paleozoic Era—also known as the â€Å"ancient life† which existed 542 to 251 million years ago; 2) Mesozoic Era—also regarded as the â€Å"middle life† which existed 251 to 65. 5 million years ago; and 3) Cenozoic Era—dubbed as the â€Å"recent life,† which has existed since 65. 5 million years ago up to the present time (Gore 1). The Paleozoic Era appears to be the first period from the Phanerozoic Eon when the earliest complex life forms first existed. The Early Paleozoic specifically can be further divided into three periods such as the 1. ) Cambrian, 2. ) Ordovician, and the 3. ) Sulirian periods. It was during the earlier parts of the Paleozoic era when major advances in biological evolution were dated. The first of such developments and evolutions was that of the Cambrian Explosion. After this highlight came the developments of some group of green algae from the Ordovician period. This development in the early forms of primitive plants led to the evolutions of vertebrates since most plants during that time were found to move from water to land (Farabee). The Cambrian Explosion (544-505 million years ago) The Cambrian explosion during the earliest years of the Paleozoic era has been considered as the most interesting zoological myth there is about the origin of life (Dawkins and Wong 436). This is because this was the period when the earliest known animal and plant life sprang and had left very remarkable pieces of fossils which served as their memoirs for the modern scientists of today. It was during the Cambrian period when primitive life such as Coelenterates, protozoa, poriferans, molluscans, worms, echinoderms, trilobites, tribitmorphs, achaocyathids, and brachiopods were found to rule the animal kingdom (Balisteri et al. ). However, these primitive life forms were seen only in bodies of water. The Early Cambrian period was also tagged as a â€Å"wild time† for animal evolution (Farabee). This was because within the relatively short period of time, a wide variety of body plans among animals have already developed. One of the most prevailing groups of primitive animals during that time was the trilobites. These shallow-marine dwelling organisms lived during the Cambrian period, and through the rest of the period, this group has diversified into other more complex forms of organisms (Balisteri et al. ). However, due to the massive cooling and freezing on most of the Earth’s land during this time, extinction was found very distinct in this period. As to primitive plant life during the Cambrian period, algae was found to be the major group of plant life that existed in this period. These plants were known to have secreted lime-like substances which aid in the development and formation of rocks (Balisteri et al. ). Also, plants were found to have inhabited the lands first before the animals did during the Cambrian period. It was also during this period when the world’s primitive supercontinent, Pangaea, was believed to start breaking apart (Balisteri et al. ). During the Cambrian period, the large continent of the North America moved upward the globe through the equator. Gondwana, which is the largest remaining land mass of Pangaea during that time, divided into what we know today as India, Australia, Antarctica, and South America. The Ordovician Period (505-440 million years ago) The Ordovician period was characterized by the emergence of the world’s earliest volcanoes. This caused the formation of igneous rocks from the produced ash and lava from eruptions (Balisteri et al. ). This period was also marked by the continental submergence. The most highlighted part of this event was the Late Ordovician Flood which caused continents to contract and moved closer to each other. The most popular remain of this great flood as of today is the Atlantic Ocean (Balisteri et al. ). It was also noted that sea levels were generally high during the Ordovician period. However, there were still shallow waters that have been dated and found to have depositions of shallow water carbonated rocks. These were eventually traced through the presence of mudcracks and stromatolites nowadays (Gore 6). When it comes to life form evolution, diversification will best describe the action by the survivor organisms among the many life forms that became extinct from the Cambrian period (Farabee). During this period, the earliest forms of sea vertebrates, such worm-like creatures, evolved (Christian and McNeill 123). These are the creatures were found to be the ancestors of the sharks and common fishes today. These Ordovician marine vertebrates were complete with backbone, limbs, and a nervous system which formed mainly the head. Also, the remaining species that the Cambrian period left like the brachiopods, trilobites and mollusks were reported to undergo a Jurassic evolution. Thus, the first Ordovician marine vertebrates were reported to be armored, jawless, and covered with hard shells (Balisteri et al. ). On the other hand, the development of plants from the earlier group of green algae was also a milestone during this period. Scientific studies of fossils and biochemical proofs show that modern plant species rooted from the multicellular green algae that prospered during the Ordovician period (Cartage. org). Among these green algal groups, Charophytes were found to be most dominant at that time. These algae with the rest of the other algal groups were known to reside within the cool waters of the ocean, but between 500-400 million years ago, some algal groups were found to transfer to land through various levels of adaptations and evolutions which aided them to live outside the waters (Farabee). The Sulirian Period (440-410 million years ago) This period was characterized by the evolution of scorpion-like creatures as large as modern human beings (Christian and McNeil 123). These creatures were known as Euyperiods which were known to root from the extinct family of marine arthropods (Balisteri et al. ). These creatures were averagely 3 meters long and these were known to reside in the seas. Moreover, various other creatures that were abundant in the Cambrian and Ordovician periods have decreased in number during the Silurian period. Some of these animals were the Trilobites. However, the Silurian period was also distinct for the abundance of coral reefs, cephalopods, and jawed fishes that colored up and made the waters alive during this period. The said reefs have covered what people now know as the sea floors of Wisconsin, Illinois, Ohio, New York, Lake Michigan, Lake Huron, and Lake Erie (Balisteri et al.). This period was found to be dominated by the early vascular plants—which developed tiny tubes within their structures to support the transport of nutrients—as well as varieties of insects (Paull). However, both these plants and animals went through specific challenges which threatened their early extinction during that time. These challenges were that of 1) Drying out—plants and animals would have to take sometime to adapt to a new environment like when they transfer from water to land; 2) Gas exchange—respiration also takes sometime to adapt to the change in environment these creatures had to go through; 3. ) Weight support; 4. ) Conduction; and 5. ) Reproduction—the change in environment also has great effects on the reproduction process of organisms. More often than not, the change of environment tends to slow down their reproduction ability (Farabee). In addition, the Caledonian Mountain which is currently found in Canada was found to have started to form through the collision of European and North American plates (Paull). These were the major highlights and developments during the Early Paleozoic era of life and world history. This field of study may appear too complicated and boring for most people to study. However, by going through the facts and amazing discoveries of the life forms of the past and discovering how they come to produce what life is like today, it may seem that studying where the modern life rooted from is indeed an interesting and adventurous ride through both history and science.

Why Marching Band Should Be Considered a Sport Essay Example for Free

Why Marching Band Should Be Considered a Sport Essay There may be as many as 500+ members in a marching band, each having their own part that inter-locks with the 499 others. I believe marching band should be considered a sport. Everyone must be incredibly coordinated and precise. The band as a whole, and individually must practice. Then theres all the physical stresses that you have to overcome. Coordination plays a key roll in marching. A lot of teamwork goes into it as well. All the musicians have to play in the right key, stay in step, and stay musically in time or else the entire show could be compromised. Memorizing game plays is a large roll in football and other team sports, same with band. You must remember the basic notes, key signatures, and various other musical symbols. Then there are the hundreds of sets, or where and when you have to be on the field during the show. Just one person off can throw off the entire form or melody. Athletes selected for the Olympics have trained for almost all their lives for their event. In Bellevue Wests marching training, we have a two week period of living hell, aka band camp. You basically do nothing but eat, sleep, and think band during the two hottest weeks of the entire summer. Mr. Haugen, our band director, pushes hard and some break down and quit, but in the end, the majority of the group is remaining. All thats left now is a well oiled machine, just like any sports team. I only hinted how physically demanding this â€Å"extra-curricular activity† actually is. You must carry an instrument exactly level while marching, and all your body wants to do is bounce up and down like loose luggage. Then if youre a sousaphone, like me, you have around 45-50 lb. ushing down on your shoulder as you try to elevate yourself as high as possible, as to follow correct marching form. Then you must remember that half your air as you march down the field, goes to playing your instrument. If thats not enough, youre also trapped in a dark, thick fabric uniform, squeezing the last whistles of your breath from your lungs. It may be only for 15 minutes, but even track athletes get breaks in-between events. In those god-forsaken uniforms, that quarter hour feels like centuries. For some odd reason, people have the idea that its easy to play in motion, its anything but! You must have incredible music-making skills, especially considering your bouncing up and down as you sometimes run to get to your spot. Sports are very physically strenuous and demanding, so is marching. Sports teams practice all year long to get ready to compete, we only the summer and a few weeks into school. Each individual plays such a key role in the tone and appearance of the band, its unreal. Marching band isnt just a bunch of nerds and fat guys playing tubas. Its a tight-knit brotherhood of strength and skill. Like football, if you are not in the right spot, you arent scoring the touchdown.

Analysis of effluents in chemical industry

Analysis of effluents in chemical industry Abstract: This report deals with effluent samples obtained from a Ceramic Industry, and analysis for their physicochemical properties, metallic and non-metallic ions. These parameters were compared with established international standard issued by EHS Guidelines. The heavy Ceramic Industry is an important source of pollutants to the environment. Ceramic wastewaters not only contain high suspended and total solids but also significant amounts of dissolved organics resulting in high BOD or COD loads. The method of testing for these parameters, and consequent laboratory results have been illustrated here with reference to their effect on the surrounding environment. The need for an in depth analysis and measurement of effluents, as a primary step towards wastewater treatment, has been established. Introduction Manufacturing industries are under continuous surveillance to adhere to environmental standards of pollution and control. In such situations, instead of viewing regulatory controls as extremely restrictive, they can exploit it to their benefit. By projecting itself as pro-environment, the company can work up a positive image and gain advantage against its competitors. From an economic point of view, by finding alternate methods of waste treatment, the company can save costs on disposal procedures. By recycling its wastes, the industry can also cut down on their raw material consumption. These are but a few reasons why chemical industries should devote their research and technology towards effluent analysis. Only by an assessment of their wastes, the industry would be able to focus on the method of treatment required. Waste Effluent and Environment Impact Effluent analysis and monitoring systems should be implemented for all activities that may be recognized as having potential impact on the environment. Waste treatment and effluent disposal usually depends on a combination of dilution, dissipation, physical, chemical and biological means as a technique to achieve treatment. Inappropriate sitting of treatment plants, ponds and effluent disposal systems can cause nuisance to residents, compromise sensitive landscapes and natural habitats. The potential for nuisance depends on a number of variable factors including prevailing and seasonal weather conditions, topography, separation distances from residences and public facilities, the quantity, concentration and the type of effluent and the nature of the receiving water environment. These factors are required to be assessed in an integrated way when an application for waste treatment and effluent disposal system is considered Importance of Measurement The most common disposal methods are landfill and to a lesser extent incineration. Each year approximately 111 million tonnes of controlled waste (household, commercial and industrial waste) are disposed of in landfill sites in the UAE. Some waste from sewage sludge is also placed in landfill sites, along with waste from mining and quarrying. As landfill waste decomposes, methane is released in considerable quantities. Methane is a strong greenhouse gas and contributes to global warming. Furthermore, the leachate fluids formed from decomposing waste can permeate through the underlying and surrounding geological strata, polluting groundwater which may be used for drinking water supplies. Containment landfills however, can limit the spread of this waste leachate. Initially, Environment Protection Agencies came up with test methods so as to determine the amount of waste effluents released by an industry and the pollution caused by it to the environment. They intend to limit the amount of chemicals that can be hazardous if left in a final effluent and released into the surroundings. In addition to this, an accurate analysis of the effluents gives an estimate of the kind of treatment and machinery required by the industry for its treatment. It is important to determine the Emission Limit Values (ELV) for every industry so that the effluents released by them to the environment is within permissible limits. Ceramic Industry Release of waste effluents to the environment is one of the main problems of the ceramic industry. Environment issues related to ceramic industry mainly include waste water and solid wastes. Production of ceramics consumes a lot of energy, especially for the operation of a kiln for its grinding operations. Wet milling, though being the preferred method of grinding, releases waste slurry. The ingredients in glazes and the clay body itself are toxic and could be carcinogenic in their raw form. Process wastewater is mainly generated from cleaning water in preparation and casting units, and various process activities like glazing, decorating, polishing, and wet grinding. Process water is characterized by its turbidity and coloring due to very fine suspended particles of glaze and clay minerals. The potential pollutants of concern include suspended solids (e.g. clay and insoluble silicates The effluent sludge primarily contains: SiO2 Al2O3 Na2O Fe2O3 TiO2 MgO CaO K2O Other elemental impurities like Lithium, Strontium, Barium and Manganese are also present. Apart from these inorganic substances, it contains biologically degradable organic matter. Emission and Effluent Guidelines The following table gives the emission and effluent guidelines for the ceramic industry as provided by the General Environment, Health and Safety Guidelines Document. The chemical concentration of the effluent should not exceed those mentioned below: Deviation from these levels in consideration of specific, local project conditions should be justified in the environmental assessment. Test Parameters pH Conductivity Total Dissolved Solids Total Suspended Solids Oil and Grease Biological Oxygen Demand Chemical Oxygen Demand Heavy Metals, Major Metals and Trace Elements pH (Power of Hydrogen) It is the activity of dissolved hydrogen ions. It is measured with an ion-sensitive electrode which responds to hydrogen activity. Conductivity Conductivity is the degree to which a water sample can carry an electric current. The magnitude of the conductivity of a sample is a function of the amount of ions present in the sample. High conductivity can be an indicator of excessive mineralization from either natural or industrial sources. The measure of conductivity is also a good screening test which helps determine which additional testing is required. Total Solids Total Solids in an effluent is the measure of the suspended particles and dissolved substances in it. The suspended particles consist of the particulate matter that is retained by a filter and the solids that pass through the filter forms the dissolved substances. It gives an indication of the salinity, turbidity and conductance of the effluent. ie. TS = Total Dissolved Solids + Total Suspended Solids Total Dissolved Solids (mg/L) include minerals, salts, cations, anions dissolved in water. To measure TDS, The sample is filtered first and the filtrate is heated in a dish till all the water evaporates leaving behind a residue. The weight of the empty dish should be determined previously. The dish along with the residue is measured again and the difference in weight gives the TDS of the sample. Total Suspended Solids (mg/L) are solid materials suspended in water that can be trapped by a filter. To measure TSS, the effluent sample is passed through filter of preferably 0.45 micrometers. The filter weight should be determined previously. The residue on the filter is dried at around 100o C till all the water evaporates and the weight is measured again. The difference in the weight of the filter gives the TSS of the sample. Experimental Values of the Sample Prior to Treatment pH = 6.72 Salinity = 0.7 Conductivity = 1.67 S /Â ·m TSS = 2970 mg/L TDS = 1665 mg/L Total Solids = 4455 mg/L (BOD/COD to be performed) Biological Oxygen Demand Microorganisms such as bacteria are responsible for decomposing organic waste. When organic matter such as dead plants, leaves, grass clippings, manure, sewage, or even food waste is present in a water supply, the bacteria will begin the process of breaking down this waste. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria, robbing other aquatic organisms of the oxygen they need to live. Biological Oxygen Demand (BOD) is a measure of the oxygen used by microorganisms to decompose this waste. Since it is a measure of the quantity of oxygen required for biodegradation, it can be used to detect the amount of bio-degradable matter. BOD is measured by either Dilution Test (BOD5) and Manometric Test. BOD5 is the most widely used method of testing. Apparatus: 300 ml BOD bottles 2 5 liter glass bottle with siphon. 20 Â ± 1Â °C incubator DO meter Burette Nutrient Solutions: Phosphate buffer : Dissolve 8.5 g KH2P04, 21.75 g K2HP04, 33.4 g Na2HP04Â ·7H20, and 1.7 g NH4Cl in approx. 500 ml reagent water. Dilute to 1 L. The pH should be 7.2. Store in 4Â °C refrigerator. Magnesium sulfate solution : Dissolve 22.5 g MgSO4Â ·7H20 in reagent water. Dilute to 1 L Calcium chloride solution : Dissolve 27.5 g CaCl2 in reagent water. Dilute to 1 L. Ferric Chloride solution : Dissolve 0.25 g FeCl3Â ·6H20 in reagent water. Dilute to 1 L. Sample Preparation Test the effluent sample for residual chlorine. If detected, employ de-chlorination techniques and check again pH of the sample should be between 6.5- 7.5. As needed, dilute the sample with 1 N Sulfuric Acid or 1 N Sodium Hydroxide. To prevent loss of oxygen during incubation of these samples, the DO should be reduced by shaking the sample or aerating it with filtered compressed air. Blank Samples Dilution water may be prepared immediately before use, or, except for the addition of the phosphate buffer, days or weeks ahead of time. 1 ml of each nutrient solution is added per liter of dilution water. The phosphate buffer is the critical nutrient in stimulating contaminating growths so it must be added the day the water is to be used. Distilled water should be allowed to equilibrate in the incubator or with outside air for at least 24 hours at 20Â °C before use. To avoid dust or dirt contamination while allowing oxygenation, use a paper towel, cotton plug, or sponge to cover the bottle opening. The BOD bottle is filled by slowly adding sufficient dilution water so that the stopper can be inserted without leaving an air bubble Completely fill two BOD bottles with dilution water to be incubated as blanks. Incubation and Dissolved Oxygen Determination Calibrate DO meter each day of use and check membrane of probe. Record the barometric pressure each day of analysis. Determine the DO of the two dilution water blanks and all sample bottles Place the samples and the 2 dilution water blanks in a 20 Â ± 1Â °C incubator for 5 days. Fill water seals with dilution water and cap to reduce evaporation from seals. Check daily, add water to seals if necessary. Before removing the caps, pour off the water above the cap. After 5 days, determine the DO of the two dilution water blanks and the sample bottles. Calculation The BOD is calculated using the difference between the initial and final dissolved oxygen levels in the sample. This value is multiplied by the dilution factor which is the ratio of bottle volume to sample volume. Chemical Oxygen Demand The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater. The contamination level is determined by measuring the equivalent amount of oxygen required to oxidize organic matter in the sample. COD differs from BOD in that it measures the oxygen demand to digest all organic content, not just that portion which could be consumed by biological processes. A COD test measures all organic carbon with the exception of certain aromatics (benzene, toluene, phenol, etc.) which are not completely oxidized in the reaction. COD is a chemically chelated/thermal oxidation reaction, and therefore, other reduced substances such as sulfides, sulfites, and ferrous iron will also be oxidized and reported as COD. NH3-N (ammonia) will NOT be oxidized as COD. COD can be measured by the closed reflux titrimetric method and the closed reflux colorimetric method Reactor: The heater, or reactor, is used to obtain fast organic reactions. Since it is vital that the reaction take place at 150Â °C (Â ±2Â °C) for 2 hours it is important to ensure accurate pre-heating.. The reactor is equipped with a timer to notify the operator when the reaction is completed. Titration: A sample is refluxed in strongly acidic solution with a known excess of potassium dichromate (K2Cr207). After digestion the remaining unreduced K2Cr207 is titrated with ferrous ammonium sulphate to determine the amount of K2Cr207 consumed and the oxidizable matter is calculated in terms of oxygen equivalent. This procedure is applicable to COD values between 40 and 400 mg/L. Higher COD values can be obtained by careful dilution or by using higher concentrations of dichromate digestion solution Colorimetric: When a sample is digested, COD material in that sample is oxidized by the dichromate ion. The result is the change in chromium from the hexavalent (VI) to the trivalent (III) state. Both chromium species exhibit a color and absorb light in the visible region of the spectrum. In the 400 nm region the dichromate ion (Cr2072-) absorbs strongly while the chromic ion (Cr3+) absorbs much less. In the 600 nm region it is the chromic ion that absorbs strongly and the dichromate ion has nearly zero absorption. This method covers the ranges from 0 to 15000 mg/L 02 0- 150 mg/L near 420 nm 0-1000 (1500) mg/L near 600 nm 0-15000 mg/L near 600 nm The US Environmental Protection Agency specifies that the only acceptable reportable measuring method for COD is the colorimetric dichromate method. Advantages in using this method include high accuracy, certifiable results and abate chloride interference. The chemical oxygen demand (COD) test is widely used as a means of measuring the organic strength of domestic and industrial wastes. This test allows measurement of a waste in terms of the total quantity of oxygen required for oxidation to carbon dioxide and water. It is based upon the fact that all organic compounds, with a few exceptions, can be oxidized by the action of strong oxidizing agents under acid conditions. The amino nitrogen will be converted to ammonia nitrogen. However, organic nitrogen in higher oxidation states will be converted to nitrate. During the determination of CID, organic matter is converted to carbon dioxide and water regardless of the biological assimilability of the substances. For example, glucose and lignin are both oxidized completely. As a result, COD values are greater than BOD values and may be much greater when significant amounts of biologically resistant organic matter is present. Wood-pulping wastes are excellent examples because of their high lignin content. One of the chief limitations of the COD test is its inability to differentiate between biologically oxidizable and biologically inert organic matter. In addition, it does not provide any evidence of the rate at which the biologically active material would be stabilized under conditions that exist in nature. History of the COD Test Chemical oxidizing agents have long been used for measuring the oxygen demand of polluted waters. Potassium permanganate solutions were used for many years, and the results were referred to as oxygen consumed from permanganate. The oxidation caused by permanganate was highly variable with respect to various types of compounds, and the degree of oxidation varied considerably with the strength of reagent used. Oxygen-consumed values were always considerable less than 5-day BOD values. This fact demonstrated the inability of permanganate to carry the oxidation to any particular end point. Ceric sulfate, potassium iodate, and potassium dichromate are other oxidizing agents that have been studied extensively for the determination of chemical oxygen demand. Potassium dichromate has been found to be the most practical of all, since it is capable of oxidizing a wide variety of organic substances almost completely to carbon dioxide and water. Because all oxidizing agents must be used in excess, it is necessary to measure the amount of excess remaining at the end of the reaction period in order to calculate the amount actually used in t he oxidation of the organic matter. It is relatively easy to measure any excess of potassium dichromate, an important point in its favor. In order for potassium dichromate to oxidize organic matter completely, the solution must be strongly acidic and at an elevated temperature. As a result, volatile material originally present and those formed during the digestion period are lost unless provision is made to prevent their escape. Reflux condensers are ordinarily used for this purpose and allow the sample to be boiled without significant loss of volatile organic compounds. Certain organic compounds, particularly low molecular weight fatty acids, are not oxidized by dichromate unless a catalyst is present. It has been found that silver ion acts effectively in this capacity. Aromatic hydrocarbons and pyridine are not oxidized under any circumstances. Chemical Oxygen Demand By Dichromate Potassium dichromate is a relatively cheap compound that can be obtained in a high state of purity. The analytical-reagent grade, after drying at 103 oC, can be used to prepare solutions of an exact normality by direct weighing and dilution to the proper volume. The dichromate ion is a very potent oxidizing agent in solutions that are strongly acidic. The reaction involved in the usual case, where organic nitrogen is all in a reduced state(oxidation number of -3), may be represented in a general way as follows: CnHaObNc + dCr2O2-7 + (8d +c)H+ nCo2 + (a+ 8d-3c)/2 H2O + cNH+4 + 2dCr3+ Where d = 2n/3 +a/6 b/3 c/2. For these and other reasons, dichromate approaches an ideal reagent for the measurement of COD. Selection of Normality COD results are reported in terms of milligrams of oxygen, Since the equivalent weight of oxygen is 8 g, it would seem logical to use a N/8 or 0.25 N solution of oxidizing agent in the determination so that results can be calculation in accordance with the general procedure. Experience with the test has shown it has sufficient sensitivity to allow the use of a stronger solution of dichromate, and a N/4 or 0.25N solution is recommended. This allows the use of larger samples by doubling the range of COD that can be measured in the test procedure, since each milliliter of a 0.25 N solution of dichromate is equivalent to 2 mg of oxygen. In any method of measuring COD, an excess of oxidizing agent must be present to ensure that all organic matter in oxidized as completely as is within the power of the reagent. This requires that a reasonably excess be present in all samples. In it necessary, of course, to measure the excess in some manner so that the actual amount reduced can be determined. A solution of a reducing agent is ordinarily used. Nearly all solutions of reducing agents are gradually oxidized by oxygen dissolved from the air unless special care is taken to protect them from oxygen. Ferrous ion is an excellent reducing agent for dichromate. Solutions of it can be best prepared from ferrous ammonium sulfate which is obtainable in rather pure and stable form. In solutions, however, it is slowly oxidized by oxygen, and standardization is required each time the reagent is to be used. The standardization is made with the 0.25N solution of dichromate. The reaction between ferrous ammonium sulfate and dichromate may be represented as follows: 6Fe2+ + Cr2O2-7 + 14H+ - 6Fe3+ + 2Cr3+ + 7H2O Blanks Both the COD and BOD tests are designed to measure oxygen requirements by oxidation of organic matter present in the samples. It is important, therefore, that no organic matter from outside sources be present if a true measure of the amount present in the sample is to obtained. Since it is impossible to exclude extraneous organic matter in the BOD test and impractical to do so in the COD test, blank samples are required in both determinations. Indicator A very marked change in oxidation-reduction potential (ORP) occurs at the end point of all oxidation-reduction reactions. Such changes may be readily detected by electrometric means if the necessary equipment is available. Oxidation-reduction indicators may also be used; Ferroin (ferrous 1,10-phenanthroline sulfate) is an excellent one to indicate when all dichromate has been reduced by ferrous ion. It gives a very sharp brown color change that is easily detected in spite of the blue color produced by the Cr3+ formed on reduction of the dichromate. Calculations Although an oxidizing agent is used in the measurement of COD, it does not figure directly in the calculation of COD. This is because a solution of reducing agent must be used to determine how much of the oxidizing agent was used, and it is simpler to relate everything to the reducing agent in this case, because its strength varies from day to day and its normality is seldom, if ever, exactly equal to 0.25N. Calculation of COD is made using the following formula : COD(mg/L) = 8000 (blank titr. sample titr.) [norm. Fe(Nh4)2(SO4)2] mL sample Methods to Reduce Hazardous Waste Generation The COD test can generate a large volume of liquid hazardous waste. In the past, common practice was to dilute completed samples with tap water and discharge them down the drain with a good flushing of water. This meant that considerable quantities of acid, chromium, silver, and also mercury (added for chloride complexation) could reach a treatment plant and perhaps surface waters. For this reason, drain disposal is now discouraged and sometimes prohibited, and so spent solutions must be stored, packaged and disposed into approved hazardous waste storage sites. It is possible to reduce this problem by recovering silver and mercury from the samples, but this requires proper permitting. In order to reduce this problem, alternate procedures can be used. Standard Methods now offers two closed reflux methods in which smaller sample and reagent volumes are used. Refluxing here is conducted in sealed containers. However, the principles are essentially the same as in the more historical open -reflux method. In order to maintain sufficient sensitivity with the reduced volumes, the concentration of the ferrous ammonium sulfate titrant is reduced. In one variation, a colorimetric rather than a volumetric procedure is used. This takes advantage of the change during organic oxidation from orange color of Cr(VI), which absorb at 420 nm. Measurements of color change from sample oxidation at either wavelength can be used for quantification. Although costs of prepared reagents for the closed flux COD procedures from commercial companies tend to be high, many analysts prefer them in comparison with reagents for the conventional reflux procedure because of their easy in use and reduction in quantities of resulting waste chemicals requiring disposal. While these considerations tend to support the use of the closed reflux procedure, a similar variation can be made with the open reflux procedure as well. Here, for example, a 10 mL rather than a 50mL samples can be used. In this case, only 5 mL of dichromate solution is added together with only 15 mL of Ag+ amended concentrated sulfuric acid. By reducing the concentration of the ferrous ammonium sulfate titrant from 0.25 N to 0.025 N, suitable sensitivity can still be maintained. The sample reflux apparatus as used with larger samples works satisfactorily here. With this modification, only one-fifth of the volume of waste solutions are generated, and little sacrifice in analytical precision is made. Inorganic Interferences Certain reduced inorganic ions can be oxidized under the conditions of the COD test and thus can cause erroneously high results to be obtained. Chloride causes the most serious problem because of its normally high concentration in most wastewaters. 6Cl- + Cr2O2-7 + 14H+ - 3Cl2 +2CR3+ + 7H2O Fortunately, this interference can be eliminated by the addition of mercuric sulfate to the sample prior to the addition of the other reagents. The mercuric ion combines with the chloride ions to form a poorly ionized mercuric chloride complex Hg2+ + 2Cl- HgCl2 (aq) In the presence of excess mercuric ions the chloride-ion concentration is so small that it is not oxidized to any extent by dichromate. Nitrite ix oxidized to nitrate and this interference can be overcome by the addition of sulfamic acid to the dichromate solution. However, significant amounts of nitrite seldom occur in wastes or in natural waters. This also holds true for other possible interferences such as ferrous iron and sulfide. Application of COD Data The COD test is used extensively in the analysis of industrial wastes. It is particularly valuable in surveys designed to determine and control losses to sewer systems. Results may be obtained within a relatively short time and measures taken to correct errors on the day they occur. In conjunction with the BOD test, the COD test is helpful in indicating toxic conditions and the presence og biologically resistant organic substances. The test is widely used in the operation of treatment facilities because of the speed with which results can be obtained. BOD Vs. COD To measure oxygen demand, biochemical oxygen demand (BOD) relies on bacteria to oxidize readily available organic matter during a five-day incubation period. COD uses strong chemicals to oxidize organic matter. Generally, COD is preferred to BOD for process control measurements because results are more reproducible and are available in just two hours rather than five days. By the time you have the results from a five day test, the plant conditions are no longer the same, so real time monitor and control cannot be relied upon by the use of BOD. COD is a quick and easy and the process at the wastewater treatment plant can be optimized and controlled with real time accuracy. BOD simulates the actual treatment plant process by measuring the organic material microorganisms can oxidize. Although COD is comparable to BOD, it actually measures chemically oxidizable matter. The COD test is not a direct substitute for the BOD test; however, a ratio usually can be correlated between the two tests. This requires COD versus BOD testing over a specified period of time. For industrial samples, COD is the only feasible test because of the presence of bacterial inhibitors or other chemical interferences, which would interfere with a BOD determination. Many industrial laboratories find that parallel COD and BOD testing is beneficial because the COD test can be used to target a specific BOD range. Conclusion The Ceramic Industry is a major source of pollutants to the environment. Industrial Wastes unless treated pose a threat to the environment and are extremely hazardous if left untreated. Hence evaluation of the same is of utmost important. The composition of the effluents should fall within the Emission Limit Values as specified by EHS Guidelines. Analysis of effluents forms the primary phase of Wastewater Treatment. It indicates the type of treatment required and gives an estimate of the machinery and infrastructure to be laid. Only through a thorough assessment the industry would be able to gauge the various possibilities of treatment and recycling. Summary and Future Research The study so far has identified the importance and need for effluent analysis as the first step towards treatment systems. The chemical composition of effluents released from the Ceramic Industry have been estimated and their ELVs mentioned. The tests and methods of analysis have been explained in depth and simulated in the laboratory so as to determine the chemical concentration levels of the effluent sample prior to treatment. Further tests will include an analysis of the treated samples and verification with the standard values issued by EHS Guidelines. In addition, ICP atomic spectroscopy will be used to identify the presence of elemental contaminants and a report of the same will be provided to the Ceramic Company for their reference.

Importance of Quantitative Measurements Quantitative measurements serve as the keystone of engineering practice. Environmental engineering and science is perhaps most demanding in this respect, for it requires the use of not only the conventional measuring devices employed by engineers, but, in addition, many of the techniques and methods of measurement used by chemists, physicists, and some of htose used by biologists. Every problem in environmental engineering and science must be approached initially in a manner that will define the problem. This approach necessitates the use of

Who’s Afraid of Virginia Woolf by Edward Albee Essay -- English Litera

Who’s Afraid of Virginia Woolf by Edward Albee How a Couple Denies Reality by Escaping into a World of Fantasy --------------------------------------------------------------- INTRODUCTION Edward Albee’s account of the strange relationship between George and Martha was an award-winning Broadway play and a cinema classic. As a drama, it succeeds on all levels. But like all great dramatic works, it is much more than an absorbing story.To understand their mutual cruelty and their failure to accept the world around them, we must understand why they are what they are. The following examination of the leading characters and the drama’s underlying themes will help us understand the root causes and motivations for their actions and also the means the couple use to escape from reality. One way to escape from reality is by playing a series of games. Games abound in the play. Several are mentioned explicitly: humiliate the host, hump the hostess, get the guest, bringing up baby. For the last game ,it is George who invents the rules. Martha is a build on mother whose George invented the attributes, the behaviour toward the child. The Imaginary son has both a negative and positive aspect. It is positive because the couple share a common secret and negative because the couple claim ownership of this fantasy, as for example ;when they fight for their son’s eye colour. It is negative because they used the child in a rivalry game. This game is used by George to humiliate Martha. He said (l.126)†The kid grow up neurotic ,with Martha here carrying on the way she does: sleeping till four o’clock in the afternoon ,climbing over the poor bastard.† The same game is used by Martha to blackmail George (p19 act 1).Martha ... ...unction better as a real couple in the future, and no more as a fictional one. Maybe Albee will tell us that one cannot always live in a fictional world, one day one must confront our fears instead of trying to escape. To conclude, as we have seen, the way couples try to escape from reality that has become too difficult to face is to create illusions for themselves by making up stories, by playing games, by building up false images of reality. But one cannot eternally escape from reality, one day one must take off our mask and find out our real identity and face our problems. It is what happen to George and Martha. 1.

Chromium :: essays research papers

Chromium Chromium is a very hard, brittle, gray metal, which is sometimes referred to as Siberian red lead. It does not rust easily and becomes shiny and bright when it is polished. The shiny trim on our automobile bumpers and door handles is usually electroplated chromium. Most chromium comes from something called chromite which is a mixture of chromium , iron, and oxygen. Chromite is a common rather ordinary black mineral that no one really noticed until more recent times. Nearly all the world's supply of chromite comes from Zimbabwe, Russia, Turkey, South Africa, Cuba, and the Philippines. The United States imports almost all its chromite. Chromium is added to other metals to make them harder and more resistant to chemicals. Small quantities mixed with steel make the metal stainless. Stainless steel is used to make cutlery and kitchen equipment because it does not rust easily and takes a mirror-like polish. This steel contains about 13 percent chromium and 0.3 percent carbon. The hardness of steel can be increased by adding small quantities of chromium to it. Chromium steel alloys (mixtures containing one or more metals) are used to make armor plating for tanks and warships. They are also used for ball bearings and the hard cutting edges of high-speed machine tools. Nickel is highly resistant to electric current and is often added to chromium steels to make them easier to work. For example, stainless steel sinks can be pressed out from flat sheets of steel that can contain 18 percent chomium and 8 percent nickel. When nickel is mixed with chromium, the resulting metal can stand very high temperatures without corroding. For example, the heating elements of toasters can be made from an alloy that is 80 percent nickel and 20 percent chromium. This metal operates at a temperature of about 1380 degrees Fahrenheit (750 degrees Celsius). Chromium was discovered in 1798 by the French chemist Nicolas Vauquelin. He chose the name chromium from the Greek word chroma, which means color. Chromium was a good choice of name, many chromium compounds are brightly colored. Rubies are red and emeralds are green because they contain chromium compounds. Some of the brightest colors in the artist's palette contain chromium. Chrome yellow is made from a substance which contains chromium, lead, and oxygen. Zinc yellow contains zinc, chromium and oxygen. Chrome red is another chromium compound. Chrome green is used in paints and in printing cotton

Physics of Dog Mushing :: sport Physics Dogs Dog Racing

Acceleration/Velocity Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia. The lager mass an object has the the more weight it has and the more inertia it has. Weight effects acceleration by increasing friction. Friction is f =  µN where  µ is the coefficient of friction, N is the normal force, and f is friction. The normal force is equal to mass times gravity assuming no other downward forces are applied. Therefore the more weight in both sled gear and musher the dogs have to haul the lower the velocity and the slower the acceleration will be due to friction between the runners and the ground. Inertia effects acceleration because inertia is the tendency of objects to ether stay at rest or stay in motion. In this case since the point is to move we are more concerned about staying at rest. When starting the dogs have to pull harder to get the sled moving then they do to keep it moving to both overcome the effects of inertia and to change the fiction from static friction to kinetic friction. Force/Work Force is necessary to start all motion, and in the presence of friction force is needed to maintain a constant velocity. In mushing a vast majority of the force comes from the dogs, and depending on the musher as a small amount to no force comes from the musher (assuming flat terrain). Mathematically F = ma where "F" is force, "m" is mass, and "a" is acceleration. this tells us that if the velocity is constant then the sum of the forces equals 0(F = 0). this doesn't mean the dogs aren't applying any force it just means that they are only applying enough force to over come any friction that might be resting the forward motion. The dogs apply this force by pulling on the tug lines which leads to a gangline which is attached to the sled. some mushers place a shock absorber between the sled and the gangline to both ease jolts from the dogs accelerating from a stop and to reduce the jolt on the dogs from large bumps in the trails. Work The dogs are only doing work when they are accelerating because W = Fd where W is work, F is force, and d is distance.

National Territory of the Philippines Essay

The Constitution of the Philippines (Filipino: Saligang Batas ng Pilipinas) is the supreme law of the Philippines. The Constitution currently in effect was enacted in 1987, during the administration of President Corazon Aquino, and is popularly known as the â€Å"1987 Constitution†.[1] Philippine constitutional law experts recognize three other previous constitutions as having effectively governed the country — the 1935 Commonwealth Constitution, the 1973 Constitution, and the 1986 Freedom Constitution.[2][3] Constitutions for the Philippines were also drafted and adopted during the short-lived governments of Presidents Emilio Aguinaldo (1898) and Josà © P. Laurel (1943). †¢Ã‚  Background of the 1987 ConstitutionIn 1986, following the People Power Revolution which ousted Ferdinand Marcos as president, and following on her own inauguration, Corazon Aquino issued Proclamation No. 3, declaring a national policy to implement the reforms mandated by the people, protecting their basic rights, adopting a provisional constitution, and providing for an orderly translation to a government under a new constitution.[4] President Aquino later issued Proclamation No. 9, creating a Constitutional Commission (popularly abbreviated â€Å"Con Com† in the Philippines) to frame a new constitution to replace the 1973 Constitution which took effect during the Marcos martial law regime. Aquino appointed 50 members to the Commission. The members of the Commission were drawn from varied backgrounds, including several former congressmen, a former Supreme Court Chief Justice (Roberto Concepcion), a Catholic bishop (Teodoro Bacani) and film director (Lino Brocka). Aquino also deliberately appointed 5 members, including former Labor Minister Blas Ople, who had been allied with Marcos until the latter’s ouster. After the Commission had convened, it elected as its president Cecilia Muà ±oz-Palma, who had emerged as a leading figure in the anti-Marcos opposition following her retirement as the first female Associate Justice of the Supreme Court. The Commission finished the draft charter within four months after it was convened. Several issues were heatedly debated during the sessions, including on the form of government to adopt, the abolition of the death penalty, the continued retention of the Clark and Subic American military bases, and the integration of economic policies into the Constitution. Brocka would walk out of the Commission  before its completion, and two other delegates would dissent from the final draft. The ConCom completed their task on October 12, 1986 and presented the draft constitution to President Aquino on October 15, 1986. After a period of nationwide information campaign, a plebiscite for its ratification was held on February 2, 1987. More than three-fourth of all votes cast, 76.37% (or 17,059,495 voters) favored ratification as against 22.65% (or 5,058,714 voters) who voted against ratification. On February 11, 1987, the new constitution was proclaimed ratified and took effect. On that same day, Aquino, the other government officials, and the Armed Forces of the Philippines pledged allegiance to the Constitution. Significant features of the 1987 Constitution The Constitution establishes the Philippines as a â€Å"democratic and republican State†, where â€Å"sovereignty resides in the people and all government authority emanates from them†. (Section 1, Article II) Consistent with the doctrine of separation of powers, the powers of the national government are exercised in main by three branches — the executive branch headed by the President, the legislative branch composed of Congress and the judicial branch with the Supreme Court occupying the highest tier of the judiciary. The President and the members of Congress are directly elected by the people, while the members of the Supreme Court are appointed by the President from a list formed by the Judicial and Bar Council. As with the American system of government, it is Congress which enacts the laws, subject to the veto power of the President which may nonetheless be overturned by a two-thirds vote of Congress (Section 27(1), Article VI). The President has the constit utional duty to ensure the faithful execution of the laws (Section 17, Article VII), while the courts are expressly granted the power of judicial review (Section 1, Article VIII), including the power to nullify or interpret laws. The President is also recognized as the commander-in-chief of the armed forces (Section 18, Article VII). The Constitution also establishes limited political autonomy to the local government units that act as the municipal governments for provinces, cities, municipalities, and barangays. (Section 1, Article X) Local governments are generally considered as falling under the executive branch, yet local legislation requires enactment by duly elected local legislative  bodies. The Constitution (Section 3, Article X) mandated that the Congress would enact a Local Government Code. The Congress duly enacted Republic Act No. 7160, The Local Government Code of 1991, which became effective on 1 January 1992.[5] The Supreme Court has noted that the Bill of Rights â€Å"occupies a position of primacy in the fundamental law†.[6] The Bill of Rights, contained in Article III, enumerates the specific protections against State power. Many of these guarantees are similar to those provided in the American constitution and other democratic constitutions, including the due process and equal protection clause, the right against unwarranted searches and seizures, the right to free speech and the free exercise of religion, the right against self-incrimination, and the right to habeas corpus. The scope and limitations to these rights have largely been determined by Philippine Supreme Court decisions. Outside of the Bill of Rights, the Constitution also contains several other provisions enumerating various state policies including, i.e., the affirmation of labor â€Å"as a primary social economic force† (Section 14, Article II); the equal protection of â€Å"the life of the mother and the life of the unborn from conception† (Section 12, Article II); the â€Å"Filipino family as the foundation of the nation† (Article XV, Section 1); the recognition of Filipino as â€Å"the national language of the Philippines† (Section 6, Article XVI), and even a requirement that â€Å"all educational institutions shall undertake regular sports activities throughout the country in cooperation with athletic clubs and other sectors.† (Section 19.1, Article XIV) Whether these provisions may, by themselves, be the source of enforceable rights without accompanying legislation has been the subject of considerable debate in the legal sphere and within the Supreme Court. The Court, for example, has ruled that a provision requiring that the State â€Å"guarantee equal access to opportunities to public service† could not be enforced without accompanying legislation, and thus could not bar the disallowance of so-called â€Å"nuisance candidates† in presidential elections.[7] But in another case, the Court held that a provision requiring that the State â€Å"protect and advance the right of the people to a balanced and healthful ecology† did not require implementing legislation to become the source of operative rights.[8] Historical constitutions Constitution of Biak-na-Bato (1897) The Katipunan revolution led to the Tejeros Convention where, at San Francisco de Malabon, Cavite, on March 22, 1897, the first presidential and vice presidential elections in Philippine history were held—although only the Katipuneros (members of the Katipunan) were able to take part, and not the general populace. A later meeting of the revolutionary government established there, held on November 1, 1897 at Biak-na-Bato in the town of San Miguel de Mayumo in Bulacan, established the Republic of Biak-na-Bato. The republic had a constitution drafted by Isabelo Artacho and Fà ©lix Ferrer and based on the first Cuban Constitution.[9] It is known as the â€Å"Constitucià ³n Provisional de la Repà ºblica de Filipinas†, and was originally written in and promulgated in the Spanish and Tagalog languages.[10] Malolos Constitution (1899) The Malolos Constitution was the first republican constitution in Asia.[11] It declared that sovereignty resides exclusively in the people, stated basic civil rights, separated the church and state, and called for the creation of an Assembly of Representatives to act as the legislative body. It also called for a Presidential form of government with the president elected for a term of four years by a majority of the Assembly.[12] It was titled â€Å"Constitucià ³n polà ­tica†, and was written in Spanish following the declaration of independence from Spain,[13] proclaimed on January 20, 1899, and was enacted and ratified by the Malolos Congress, a Congress held in Malolos, Bulacan.[14][15] Acts of the United States Congress The Philippines was a United States Territory from December 10, 1898 to March 24, 1934.[16] As such, the Philippines was under the jurisdiction of the federal government of the United States during this period. Two acts of the United States Congress passed during this period can be considered Philippine constitutions in that those acts defined the fundamental political principles, and established the structure, procedures, powers and duties, of the Philippine government. 1.The Philippine Organic Act of 1902, sometimes known as the â€Å"Philippine Bill of 1902†, was the first organic law for the Philippine Islands enacted by the United States Congress. It  provided for the creation of a popularly elected Philippine Assembly, and specified that legislative power would be vested in a bicameral legislature composed of the Philippine Commission (upper house) and the Philippine Assembly (lower house). Its key provisions included a bill of rights for the Filipinos and the appointm ent of two nonvoting Filipino resident commissioners to represent the Philippines in the United States Congress. 2.The Philippine Autonomy Act of 1916, sometimes known as â€Å"Jones Law†, modified the structure of the Philippine government by removing the Philippine Commission as the legislative upper house, replacing it with a Senate elected by Filipino voters. This act also explicitly stated that it was and had always been the purpose of the people of the United States to withdraw their sovereignty over the Philippine Islands and to recognize Philippine independence as soon as a stable government can be established therein. Though not a constitution itself, the Tydings-McDuffie Act of 1934 provided authority and defined mechanisms for the establishment of a formal constitution via a constitutional convention. Commonwealth and Third Republic (1935) The 1935 Constitution was written in 1934, approved and adopted by the Commonwealth of the Philippines (1935-1946) and later used by the Third Republic of the Philippines (1946-1972). It was written with an eye to meeting the approval of the United States Government as well, so as to ensure that the U.S. would live up to its promise to grant the Philippines independence and not have a premise to hold onto its â€Å"possession† on the grounds that it was too politically immature and hence unready for full, real independence. The original 1935 Constitution provided for unicameral National Assembly and the President was elected to a six-year term without re-election. It was amended in 1940 to have a bicameral Congress composed of a Senate and House of Representatives, as well the creation of an independent electoral commission. The Constitution now granted the President a four-year term with a maximum of two consecutive terms in office. A Constitutional Convention was held in 1971 to rewrite the 1935 Constitution. The convention was stained with manifest bribery and corruption. Possibly the most controversial issue was removing the presidential term limit so that Ferdinand E. Marcos could seek election for a third term, which many  felt was the true reason for which the convention was called. In any case, the 1935 Constitution was suspended in 1972 with Marcos’ proclamation of martial law, the rampant corruption of the constitutional process providing him with one of his major premises for doing so. Second Republic (1943) The 1943 Constitution was drafted by a committee appointed by the Philippine Executive Commission, the body established by the Japanese to administer the Philippines in lieu of the Commonwealth of the Philippines which had established a government-in-exile. In mid-1942 Japanese Premier Hideki Tojo had promised the Filipinos â€Å"the honor of independence† which meant that the commission would be supplanted by a formal republic. The Preparatory Committee for Philippine Independence tasked with drafting a new constitution was composed in large part, of members of the prewar National Assembly and of individuals with experience as delegates to the convention that had drafted the 1935 Constitution. Their draft for the republic to be established under the Japanese Occupation, however, would be limited in duration, provide for indirect, instead of direct, legislative elections, and an even stronger executive branch. Upon approval of the draft by the Committee, the new charter was ra tified in 1943 by an assembly of appointed, provincial representatives of the Kalibapi, the organization established by the Japanese to supplant all previous political parties. Upon ratification by the Kalibapi assembly, the Second Republic was formally proclaimed (1943-1945). Josà © P. Laurel was appointed as President by the National Assembly and inaugurated into office in October 1943. Laurel was highly regarded by the Japanese for having openly criticised the US for the way they ran the Philippines, and because he had a degree from Tokyo International University. The 1943 Constitution remained in force in Japanese-controlled areas of the Philippines, but was never recognized as legitimate or binding by the governments of the United States or of the Commonwealth of the Philippines and guerrilla organizations loyal to them. In late 1944, President Laurel declared a state of war existed with the United States and the British Empire and proclaimed martial law, essentially ruling by decree. His government in turn went into exile in December, 1944, first to Taiwan and then Japan. After the announcement of Japan’s surrender, Laurel formally proclaimed the Second Republic as dissolved. Until the  1960s, the Second Republic, and its officers, were not viewed as legitimate or as having any standing, with the exception of the Supreme Court whose decisions, limited to reviews of criminal and commercial cases as part of a policy of discretion by Chief Justice Josà © Yulo continued to be part of the official records (this was made easier by the Commonwealth never constituting a Supreme Court, and the formal vacancy in the chief justice position for the Commonwealth with the execution of Chief Justice Josà © Abad Santos by the Japanese). It was only during the Macapagal administration that a partial, political rehabilitation of the Japanese-era republic took place, with the recognition of Laurel as a former president and the addition of his cabinet and other officials to the roster of past government officials. However, the 1943 charter was not taught in schools and the laws of the 1943-44 National Assembly never recognized as valid or relevant. The 1943 Constitution provided strong executive powers. The Legislature consisted of a unicameral National Assembly and only those considered as anti-US could stand for election, although in practice most legislators were appointed rather than elected. The New Society and the Fourth Republic (1973) The 1973 Constitution, promulgated after Marcos’ declaration of martial law, was supposed to introduce a parliamentary-style government. Legislative power was vested in a National Assembly whose members were elected for six-year terms. The President was ideally supposed to be elected as the symbolic and purely ceremonial head of state from the Members of the National Assembly for a six-year term and could be re-elected to an unlimited number of terms. Upon election, the President ceased to be a member of the National Assembly. During his term, the President was not allowed to be a member of a political party or hold any other office. Executive power was meant to be exercised by the Prime Minister who was also elected from the Members of the National Assembly. The Prime Minister was the head of government and Commander-in-Chief of the armed forces. This constitution was subsequently amended four times (arguably five depending on how one considers Proclamation No. 3 of 1986). On October 16-17 1976, a majority of barangay voters (Citizen Assemblies) approved that martial law should be continued and ratified the amendments to the Constitution proposed  by President Marcos.[19] The 1976 amendments were: †¢an Interim Batasang Pambansa (IBP) substituting for the Interim National Assembly †¢the President would also become the Prime Minister and he would continue to exercise legislative powers until martial law should have been lifted. The Sixth Amendment authorized the President to legislate: Whenever in the judgment of the President there exists a grave emergency or a threat or imminence thereof, or whenever the Interim Batasang Pambansa or the regular National Assembly fails or is unable to act adequately on any matter for any reason that in his judgment requires immediate action, he may, in order to meet the exigency, issue the necessary decrees, orders or letters of instructions, which shall form part of the law of the land. The 1973 Constitution was further amended in 1980 and 1981. In the 1980 amendment, the retirement age of the members of the Judiciary was extended to 70 years. In the 1981 amendments, the false parliamentary system was formally modified into a French-style semi-presidential system: †¢executive power was restored to the President; †¢direct election of the President was restored; †¢an Executive Committee composed of the Prime Minister and not more than fourteen members was created to â€Å"assist the President in the exercise of his powers and functions and in the performance of his duties as he may prescribe;† and the Prime Minister was a mere head of the Cabinet. †¢Further, the amendments instituted electoral reforms and provided that a natural born citizen of the Philippines who has lost his citizenship may be a transferee of private land for use by him as his residence. The last amendments in 1984 abolished the Executive Committee and restored the position of Vice-President (which did not exist in the original, unamended 1973 Constitution). In actual practice, while the 1973 Constitution was ideally supposed to set up a true parliamentary system, the late President Marcos had made use of subterfuge and manipulation in order to keep executive power for himself, rather than devolving executive powers to the Parliament, as headed by the Prime Minister. The end result was that the 1973 Constitution – due to all amendments and subtle manipulations – was  merely the abolition of the Senate and a series of cosmetic text-changes where the old American-derived terminologies such House of Representatives became known as the â€Å"Batasang Pambansa† (National Assembly), Departments became known as â€Å"Ministries†, cabinet secretaries became known as â€Å"cabinet ministers†, and the President’s assistant – the Executive Secretary – became known as the â€Å"Prime Minister.† Ultimately, Marcos’ so-called â€Å"Parliamentary System† therefore functioned as an authoritarian-run Presidential System due to the series of amendments and other modifications put in place after the 1973 Constitution was ratified. 1986 â€Å"Freedom Constitution† Following the EDSA People Power Revolution that removed President Ferdinand E. Marcos from office, the new President, Corazon C. Aquino issued Proclamation No. 3 as a provisional constitution to would prepare for the next constitution. It adopted certain provisions from the 1973 constitution and granted the President broad powers to reorganise the government and remove officials from office, and mandated that the president would appoint a commission to draft a new constitution. refference/source; # a b â€Å"The 1987 Constitution of the Republic of the Philippines†. 15 October 1986. http://www.thecorpusjuris.com/laws/constitutions/8-philippineconstitutions/70-1987-constitution.html.
