Poverty and Its Effect on Society free essay sample

In any case, while the U. S. has announced such high numbers in GDP, we rank third in destitution with a 17% neediness rate. This positioning is among the main thirty of the Organization for Economic Co-activity and Development (OECD) countries on the planet. Just Mexico and Turkey rank higher than our nation (Ranking America, Blog at WordPress. com). Destitution and Its Effects on Society The ailment of neediness in the U. S. isn't new, however it is one that has stayed a consistent, even as our country developed into a world superpower. While perspectives have gradually moved with respect to the individuals who are viewed as living at and underneath the neediness level, the country still can't seem to completely endeavor to tackle the issue in way that would truly discover a fix. In 2011, the Annie E. Casey Foundation detailed that one out of five kids, 14. 7 million or 20 percent, lived beneath the neediness level. This number is up from 17% in 2000 (Report: Child neediness Rate Hits 20 percent in U. S. as families battle; Christian Science Monitor). The all out number of individuals living beneath the neediness level is at its most noteworthy, 46. million as detailed by the U. S. Statistics Bureau, which is the most elevated number since the Bureau started distributing its records in 1959(Total U. S. Populace living underneath the destitution line; U. S. Evaluation Bureau). Also, albeit a few gatherings are influenced by destitution more than others, nobody, paying little mind to race or age, is invulnerable to the malady. The absolute number of individuals living underneath the destitution line influences the U. S. Gross domestic product, wrongdoing, and has caused a significant hole in the have and the poor in the country. The present downturn has extremy affected individuals living in destitution and the ongoing involve development, paying little mind to any ones assessment of it, has uncovered the developing disappointment that numerous in the country feel toward enterprises and the minority who appear to be just getting more extravagant while more individuals the country over slip underneath the neediness line. In 2007, the administration arranged 37 million men, ladies, and kids 12. 5 percent of the populace â€as poor (Macionis, 2010, p. 288). Consistently, we pass individuals living in the city, youngsters go to class wearing a similar garments and get the main dinner they will eat that day, and millions individuals rest without food or satisfactory haven. Destitution can influence ones instructive status, and various reports refer to how neediness and unexpected weakness are interlaced. The quantity of individuals living in neediness is likewise, in certain sentiments an issue of national security. Perspectives toward the poor have changed in this country throughout the years. In nineteenth and mid twentieth century America, the poor were now and again sent to poor houses or homesteads where they worked in return for food and asylum. Significant urban areas essential methods for managing stranded youngsters were to placed them into â€Å"Pauper apprenticeships† where they worked for a person who, in return, furnished them with the fundamental necessities of life. A significant number of these youngsters were regularly manhandled and utilized more as slave work. During the incredible wretchedness, when the majority of the country was reeling from the impacts of the securities exchange crash, the lines between classes obscured, and numerous who had once been working or white collar class, or exceptionally well-off, wound up in the soup lines directly close to those they may have once disregarded. Unfortunately, a considerable lot of us today have that equivalent demeanor toward poor people and destitute. During the special seasons we drop cash in the foundation pot for the Salvation Army, purchase nourishment for food closets’, and give old garments and covers toward the year's end for a tax benefit. Be that as it may, at long last we overlook the individuals who are battling simply like they were years back. The thing that matters is, today, a large number of us who currently do the overlooking are potentially not very a long way from be ad libbed ourselves. In spite of the fact that the present national joblessness rate is accounted for to slant down, it is still at an amazing 8. % (Employment Situation Summary; U. S. Branch of Labor). So what should be possible to stop the developing number of the individuals who are viewed as living in neediness? The discussion is far reaching and there is by all accounts nobody right answer. In the media legislators look for someo ne else to take the blame on which side, Republican or Democrat, are at fault for the nation’s current financial wreckage. Furthermore, the involve development, which appears to move its concentration and purpose every day, has made a ton of commotion and pointed fingers at who is to blame, presently can't seem to present any solid plans on the best way to really help stem the issue of individuals who are poor. Training is, in some sentiment, the most ideal way out of destitution. Reviews from the U. S Census Bureau in 1998, 1999, and 2000 express that an individual with a secondary school degree can acquire about $7,000 more a year than somebody who didn't complete school, and an individual with only a partner degree can envision making at any rate $15,000 more (Value of an Education; EarnMyDegree. com). Despite the fact that these figures in all probability have changed because of the current monetary atmosphere, it can at present be expected that having instruction or the like is unmistakably more beneficial than being a secondary school dropout. Other than instruction, there should be a progressively engaged assault to completion neediness by regarding it as an ailment like malignancy. As indicated by the National Institute of Health, in 2011 823 million was spent in inquire about dollars on corpulence. In any case, just 15 million was spent on homelessness(Estimate of Funding of Various Research, Condition, and Disease Categories; National Institute of Health) , and information from the Department of Health and Human Services indicated that in 2011 2. million was granted to look into destitution (Poverty Research Center FY 2011 Announcement of Award, Department of Health and Human Services). Some place there is a significant separate in this nation when how much an individual weighs is a higher priority than if they have work or sufficient haven. The issue of have and those who lack wealth has existed since the time man has strolled the earth. From the beginning of time there is verification that individuals have consistent ly lived in some type of neediness whether it be as serfs, slaves, or foreigners to the U. S. living in ethnic ghettos.

The Case for Organic Agriculture - Essay Example Humus contains natural material - living tissue that has kicked the bucket and its segments are being reused. Microorganisms like microbes and parasites take a shot at natural material, separating it into its littler structure hinders that would then be able to be reclaimed up by another plant. Humus has a structure that makes it simple for living plants to discover and take up the supplements. A portion of the salts, for instance, stick on the parts of the bargains particles that are simple for plants to snatch. Humus is dynamic and continually evolving. The people group of microorganisms can be exceptionally various and steady as long as increasingly more natural issue is taken care of to the dirt to keep up each one of those tiny animals (Donahue et al. , 1983). Plants additionally need loads of water for appropriate development. Water will simply go through sand or ground rock so humus alongside the dirt holds water in the soil.where it will be accessible to plant roots. Soil gives the lattice where seeds are first sustained. At the point when the seed first begins to develop, it pushes out minor roots to start connecting with the dirt to discover water and supplements. A green, verdant stem pushes up out of the dirt aiming high since plants get vitality from the sun to cause them to develop. The water at the highest point of that stem vanishes into the air and pulls more water and supplements up from the dirt into the plant. ... Sadly, when they eat from the plants on a ranch, they are eating our food, so any cultivating framework must think about these irritations. Regular and natural ranchers adopt various strategies to these two primary issues: keeping up enough supplements to take care of the plants and shielding plants from bugs.

Such homesteads utilize concoction composts to supplant the supplements that plants remove up from the dirt. These are for the most part, mineral salts of nitrates, phosphates, and potassium. These are applied to the field as dried pellets that break down in water. By placing these supplements into the dirt, the ordinary rancher is sure that his plants will have enough for the quickest and most extreme development. Such plants frequently take up loads of water with the supplements which swells them and makes them look fat and delicious and simpler to sell obviously, every time it downpours or the ranchers waters the field, a few supplements will go with the water any place it go - in some cases into close by waterways and streams, so regularly supplements are lost while applying composts. Such outsi de supplements can in some cases disturb the sensitive environment adjusts in the waters where they end up. Regular ranchers additionally act emphatically when nuisances like creepy crawlies or weeds meddle with development of their harvests. These ranchers splash extraordinarily made toxic substances close by plants to murder off the nuisances. Numerous ranchers additionally splash 'prophylactically' before bothers show up so plants won't have any misfortunes or even markings from creepy crawly bugs. Sadly, these toxins are not explicit to one specific sort of creepy crawly.

The report will begin with the definitions of these two fields. Firstly, Risk management is a process to make decisions which plan to minimize the business losses on an organization, and reduce the number or size of these losses. For ethics, it seems like a standard aiming to comply with certain rules or to achieve certain results in particular types of situations.

Although risk is just a by-product of the financial trad ing, two parties of the trading are trying to get rid of it. However, ethics becomes the key factor in risk management. 3. Measurement Many companies define their risks during the business plan process, specifically during budgeting. A chief risk officer may call upon the heads of a company’s operating units and functional areas to prevent, detect, respond, evaluate, define. To identify financial risks associated with their business plans, Legal departments also tend to drive risk assessment because of the significance of financial costs of transgressing applicable laws and regulations. Legal- and financial-driven assessments are good starting points for the holistic approach required to meet new expectations for ethics. It is necessary to build a sustainable relationship between the ethics and risk management.

The Role Of Parents Absent Homes Are More Frequently...

Introduction Over the past 50 years families have been affected by dramatic increases in the prevalence of nonmarital childbearing, divorce, and remarriage. In the United States nearly four in ten births are to unmarried women (Ventura 2009) and the number of children under the age of 18 living in mother only families has risen from 8% in 1960 to 23% in 2010 (U.S. Census Bureau 2010). Though the thought of how upsetting it is to grow up without a father may cross people’s mind, not many people tend to think about how not having a father impacts the children as adolescents and even sometimes into adulthood. The disruption of a family structure is known to be one of the main contributing factors in juvenile delinquency. This research paper will show evidence that adolescents in father absent homes are more frequently perpetrators of crimes. The independent variable is adolescents raised in father absent homes and the dependent variable is how they are more frequently perpetrat ors of crime. The relationship and attachment a child has with his/her parents is a main contributor as to how the child will behave and develop throughout his/her life. When a father figure is absent in the household, it disrupts this parental bond that helps influence social norms and may instead cause the child to act out.

Sixth Meditation, Rene Descares

Descartes in his first meditation is skeptical about perceptual knowledge, his concern being the inability to cite the difference between the way one thinks and reasons while asleep and when awake. His argument basically is that dreams are fallacious and that they disguise to be real but in reality, he argues, they are not.Advertising We will write a custom essay sample on Sixth Meditation, Rene Descares specifically for you for only $16.05 $11/page Learn More His second argument rests upon the idea of dreams being false experiences, those that seem to be real, but are not (Descartes 16). His aim therefore is to discredit dreaming claiming that it is far from reality and that senses should be doubted. Descartes seeks to justify the argument that some sensory experiences are false, and that whatever that happens in dreams are always false. But why is this so because sensory experiences occur in both dreams and while awake. Logically it is evident that by the time of waking up, Descartes was able to distinguish between reality and a dream because he realizes that he was asleep and that whatever happened was in his sleep which means that he was able to draw a line between dreams and reality. In his first meditation, he claims that the realities in both dreaming and waking up are so similar, because most of the things and happenings in dreams were usually similar to those that happen when one is awake. The problematic issue in this argument is that at times those things that one dreams of do not exist in reality. Where then will one place and describe those things that are nonexistent in reality but existent in dreams? How can one explain an imaginary object that exists in dreams? In both waking up and dreaming, the senses are involved because were it not for them, nothing would have happened in both. He argues that whatever we dream is based on real life experiences and so, stipulates that dreams are not independent but rather borrows a lot from the real world. But it is evident that be it in dreams or when one is awake, senses are involved. A question arises here as to how one knows whether he is dreaming or he is awake because in both senses are involved. Which of the two can be assumed to be the reality (Descartes 46)? The idea of not trusting the senses therefore comes in and doubt takes center stage. As shown by Descartes, dreams and real life activities relate to each other. That is why when one is asleep; he may dream and upon waking up get into the realities of life and fail to put a clear cut distinction between the two. But the difference between the two can be that one happens in the mind and the other happens outside the mind.Advertising Looking for essay on philosophy? Let's see if we can help you!

Therefore the senses are applicable to both can be subject to doubt (Descartes 63). Descartes argues that dreaming experience and waking experience are both difficult to distinguish from each other because the visions that come in sleep could be things that are in existence in reality. By putting forth the argument that objects that deal with imaginary things are valid, then one can assume that dreams are valid because to a larger extent they are considered nonexistent in the real world. Throughout the meditations the concepts that are put forward are issues that are envisioned in the imaginary world which can as well be held in relation with objects and things of the real world.

Analysis of Lord Of the Flies essays The classic novel, Lord of the Flies, is known throughout the world for its writing style, literary devices and unique ideas. William Golding said in one American lecture that as the World War II continued, he became more and more award of mans greed and cruelty. He then said that he looked for some way in which his ideas about the evil nature of man can have a disastrous effect. He found it in the play of children.

Legal & Ethical Case Studies - elementary school Study

Legal & Ethical Studies - elementary school - Case Study Example A principal is not allowed by the law to terminate a contract without the evidence of wrong activities that prompted them to terminate the teacher’s contract. These activities include insubordination against educational rules, moral misconduct and insufficiency, and incompetence at work (Manos, 2006). In the case where by the principal and district officers terminate a contract, they should provide a written document detailed with reasons for termination in a period more than six months before the termination date. They should also conduct an impartial hearing before the board and school’s panel. In this case, the teacher was proactive and used advanced teaching methods but the principal dislikes these methods. In accordance to leadership ethics, the termination was not important (Manos, 2006). Question # 2 Conflicts do arise in school premises among students especially in the urban life where alcoholism, sexual harassment, and drugs among other misconducts take place. When a student is badly injured like in a case where a student lost his front teeth with the teacher and classmates witnessing the act, legal measures should take place. The action by the principal in sending the perpetrator out of the school was correct, but it was not enough punishment. The student ought to have been charged with felony violation or fines at the juvenile court. This extended punishment would have acted, as a lesson to other students to adhere to the zero-tolerance policy (Manos, 2006). Question # 3 Discussing question three, I agree with the parents view on the judgment about the teacher’s supervision. The fact that the teacher was in the duty of care for students in the field guarantees the injured student’s parent a right to sue this teacher. The reasons to this according to legal and ethical background for in which the teacher was supposed to supervise instruct and provide safety care to students. However, the court may justify that the injury was not foreseeable; therefore, the teacher would not have to be answerable to the court. In this case, the teacher was students’ favorite but she did not give much attention to her duty as an overseer. The standard of care to the student was not her priority. Nevertheless, her negligence may be objected due to her involvement in students’ tasks of which this has earned a chance to be their favorite teacher (Manos, 2006). Question # 4 Child abuse is a critical issues to those around the victims especially a teacher. Suspicion that a child is a victim of child abuse has to be reported to authorities. Failure to report a case in child abuse is considered misdemeanor or felony case. Serious injuries resulting from maltreatment requires a caregiver or teacher to be keen and to show interest in extracting more information about the life of the child at home. The teacher in this case did not follow the guidelines provided for suspicion of child abuse. Therefore, the teacher sho uld have faced legal liability. The court should assess the situation in an exceptional manner to bring to justice the child abusers who should face a bigger penalty, unlike the teacher. The court should consider the teacher as a third party law violator of which charges are dependent on the substantial evidence that; indeed, the teacher waited for a bigger harm to occur to the child (Manos, 2006).

College tuition Research Paper Example | Topics and Well Written Essays - 1250 words

College tuition - Research Paper Example This paper attempts to investigate the economic costs and benefits associated with college tuition. The research will also help administrative bodies and students to identify the key factors affecting the effectiveness of college education. Finally, the conclusion will suggest effective measures to minimize the benefits cost associated with college tuition. COSTS AND BENEFITS OF EDUCATION The Opportunity Costs of College Education A number of opportunity costs are associated with college education. When a student decides to get admission in college instead of earning on a job, the lost earning is the opportunity cost. Since there is large number of applicants than the available seats, the rejection of more deserving students account for opportunity cost to that college. If the enrolled student is not utilizing his capabilities efficiently, the rejected student might have proven more successful to college and the society. Furthermore, the qualified student directly suffered emotional stress and tangible loss. The Economic Costs of College Education The tuition payment made for college education is an investment in student’s future. The cost of college education is increasing with every passing year as illustrated in figure 01. Figure 01. Increasing Trends in College Pricing Source: The College Board, 2010. However, the college tuition cost considerably varies depending on the choice of college. Around 47% of the fulltime undergraduate students are enrolled into four-year colleges with tuition fees less than $9,000 per annum. Comparatively, the private four-year colleges charge students with more than $35,000 per annum. Sometimes, these colleges also offer partial scholarships and financial aid programs attracting more applicants. The average tuition and fees at a two-year college stands around 2, 713 per annum. Few of the colleges may also offer to cover all tuition costs in full scholarships. In the year 2009-10, around $154 billion was spent in providin g financial aid to college students. Benefits College education is quite beneficial investment in terms of developing human capital. The lifetime income potential of a person far increases with education and training. These days, it is vital for a person to be prepared to work in modern economies by getting reasonable education. College tuition is thus an investment in enhancing knowledge, skills, competencies, values and habits of a person. Apart from the monetary awards, various social benefits are also associated with college education. College education has remarkably decreased the public reliance on financial assistance programs leading to the generation of more tax revenues. This also increases the serving capacity of the public sector. The costs imposed by criminal justice system on the society cannot be ignored. Over the past few decades, education has resulted in decrease of crime rates. Thus, the public sector funds spend by the system on prosecution, punishment and probat ion of criminals can be utilized for social welfare. In addition, educated people are capable of forming a more interacting civil society. TUITION DATA According to the Trends in College Pricing 2010 report, increase in grant aid has resulted in decline of average tuition and fees in the recent years. However, a large number of students are still paying full tuition charges that are increasing every year. For instance, Students at four-year public colleges with no financial funding paid 7.9% more in 2010 than they

Causes of the Cuban Missile Crisis

Causes of the Cuban Missile Crisis Cuban Missile Crises Introduction Considered to be one of the most serious conflicts between the U.S and the Soviet Union during the Cold War, the Cuban missile crises brought the World a clash of democracy V.S communism with a deadly nuclear outcome. Known to the World as the Cuban Missile crises, to the Russians as the Caribbean Crises and to the Cubans and the October Crises it lasted sixteen days in October. The main characters involved were U.S President John F. Kennedy, Russian Premier Nikita Khrushchev and Cuban President Fidel Castro. The sixteen days in October 1962 was the closest time that a full out nuclear war was about to take place Background America USSR Free election No elections or fixed elections Democratic Autocratic / Dictatorship Capitalist Communist ‘Survival of the fittest Everybody helps everybody Richest world power Poor economic base Personal freedom Society controlled by the NKVD (secret police) Freedom of the media Total censorship The Cuban missile crises origins began at the end of the World War 2. After the war about to end the United States and the USSR started to disagree on the main ideas of how a post war Europe should look like. The Americans main aim of the war was to spread democracy and to spread their companys economic opportunities into Europe. This was very different to what the USSR wanted, the USSR suffered a lot during the war, and they lost a lot of people and suffered a lot of economic and social problem directly resulting from the war, because of this the USSR main post war thoughts were to protect themselves from other wars that may happen and to spread communism across the globe.   These differences between the two countries were obviously great and were bound to cause tension and problems. Origins of Russian-American Tension Ideological: The United States and the Soviet Union represented two completely different forms of government. In the United States, the government is chosen by free elections. The people have the right to form political parties so that they can voice their political opinions. They also have the right of freedom of speech and freedom of the press. In the Soviet Union, the government is chosen by the Communist Party. The people do not have the right to form their own political parties; they do not enjoy the right freedom of speech and the freedom of the press. Since these two systems of government are completely different to one another, this is bound to cause friction between the United States and the Soviet Union. Economic: The United States wanted to encourage free trade throughout the world. The Soviet Union wanted to close off her itself from international trade. Russia was afraid that trade with the West would open up Russia to western influences which would have ruined the strength of the one-party communist regime. These differences led to much bad feeling between the United States and the Soviet Union. Power rivalry: After the Second World War, with the decline of Europe, power was shared between the Soviet Union and the United States. As one superpower wanted to dominate the other, conflicts were to be expected. Immediate Causes Leading to the Cold War Early conflict between the Soviet Union and the United States began at the peace-time conferences. Their conflict was intensified after President Truman declared the Truman Doctrine and launched the Marshall Plan in 1947. Extension of Russian influence in Europe: Even before the end of the war, the Soviet Union had gradually extended its influence in Europe. By the fall of 1944, the Red Army had liberated and controlled a large part of Eastern Europe. By 1945, at the Yalta Conference, the Soviet Union obtained the Curzon Line as its new boundary line with Poland and also the control of the eastern zone of Germany. As the war was ending in May 1945, the Soviet Union quickly consolidated its control of Eastern Europe. The Red Army began by influencing the post-war elections. They intimidated the voters and changed the voting lists as they desired. Although the non-communists could still manage to get some votes, most of the votes went to the communists. As a consequence the coalition governments formed immediately after the war were largely dominated by the communists. Two of the key ministries Defense and Military (Police) were always under communist control. Stalin was not satisfied with communist control of Eastern Europe. In the meantime, he encouraged the communists to take an active part in the immediate post-war elections in Western Europe. In late 1946, the French and Italian Communists were becoming the most powerful parties in France and Italy. The reactions of the United States: Despite the increasing Russian influence in eastern and central Europe, many politicians in the United States were optimistic about the chances of co-operation with the Soviet Union after the war and did not support strong resistance against the Russian expansion. But from May 1945 onwards, the situation was changed. The U.S. government preferred a policy of strong resistance against Russia. Poor relations between the United States and the Soviet Union: The growing problem and deteriorating relations between the Soviet Union and the United States were reflected in two minor incidents in the year. Land-Lease was abruptly terminated by the United States and the Russian request for American economic aid for the purposes of post-war reconstruction was ignored by the government of the United States. NATO vs. the Warsaw Pact April 4th 1949 NATO (North Atlantic Treaty Organization) was formed by the United States, Canada, Portugal, Italy, Norway, Denmark, Iceland, Netherlands, Luxembourg, France and the United Kingdom. NATO was set up to counter the military power of the USSR. In direct response to this, the USSR set up the Warsaw Pact consisting of Albania, Bulgaria, Czechoslovakia, Hungary, Poland, Romania, Germany, and the USSR. Dark Blue: Founding members of the North Atlantic Alliance (NATO) Light Blue: Countries that joined NATO after 1949 Dark Red: Founding members of the Warsaw Pact Light Red: Countries that joined the Warsaw Pact after 1955 Bay of Pigs The Bay of Pigs was an unsuccessful attempt by US-aided Cuban exiles to launch an attack on Cuba to overthrow Fidel Castro. The invading forces were defeated in just two days. 2506 Cuban exile invaders were killed and most of the rest captured (later traded for 58millions dollars in food and medicine aid) and approximately 4000 Cuban military men and civilians died. This deepened Cuban and American tensions, which was made worse by the Cuban Missile Crises, whose aftermath is still seen to present day. Cuban Missile Crises By 1960 the United States had a considerable nuclear advantage over the USSR, both in terms of nuclear arsenal and proximity to the USSR. The United States had 27,297 nuclear missiles compared to 3,332 for the USSR. In 1961 the United States, as a means of deterrence, placed long range ballistic nuclear missiles in Turkey, meaning that Moscow was 16 minutes away from a strike. This deeply angered the Soviet regime and they responded by placing Missiles in Cuba who had recently become an ally under President Fidel Castro. The fear that Cuba had the America might try to invade again led to negotiations between Khrushchev and Castro. In April 1962 Castro agreed to the supply surface to air missiles and surface to surface missiles to Cuba for defensive purposes. By May 1962 under Soviet control and supervision nuclear missiles were beginning to be installed in Cuba. These were transported by more than 60 Soviet ships. As named by the Soviet Union, operation Anadyr was kept tightly guarded. The USSR sent bomber plans, troops to aid in the construction and to provide expertise in the installation and use of the weapons. In all were planned to deploy 60,000 troops, three R-12 missile regiments and two R-14 missile regiments. Troops were transferred by 86 ships, Between June 17 and October 22 there were transferred 24 launching pads, 42 R-12 rockets, including six training ones, some 45 nuclear warheads, 42 Il-28 bombers, a fighter aircraft regiment (40 Mig-21 aircraft), two Anti-Air Defense divisions, three mechanized infantry regiments, and other military units some 47,000 troops in total. During this period after various leaks of information, the Soviets denied any missiles being placed in Cuba and told the Americans that they did not want to enter into any confrontation and raise tensions. American distrust of the Russians was soon confirmed. In late August an American reconnaissance plane photographed a number of installations on Cuban soil. Even with the proof President Kennedy was still convinced that these were built for defensive purposes on the part of the Cubans fearing an invasion of Cuba again by the Americans. After meeting the Soviet Ambassador, President Kennedy voiced his concerns over the installations and was constantly told not to worry, that there was no offensive missiles in Cuba and that the military buildup was insignificant. After more reconnaissance flights, using U2 manned planes, the United States was able to confirm the location and amount of nuclear missiles, this lead to confusion in the United States Government. After President Kennedy saw the photographs he brought together most of his key advisors to come up with a plan on how to deal with the threat. America intelligence stood by its convictions that the USSR would not install nuclear missiles in Cuba. The advisors quickly came up with a five different courses of action to be taken as a response to the threat. Do nothing Use diplomatic pressure to get the Soviet Union to remove the missiles An air attack on the missiles A full military invasion Naval blockade of Cuba After much careful discussions and the fear of Russian revenge if Cuba was attacked, the decisions was made to blockage the Cuban sea and stop all shipments coming into the area. The main aim was to check all ships coming into Cuba to see their cargo and examine any missiles or offensive weapons that were coming into the country. Most South American countries assisted in this blockade. At 7 p.m. October 22, President Kennedy delivered a televised radio address announcing the discovery of the missiles. Premier Khrushchev sent a message to President Kennedy saying that he considered the blockade and ‘pirate action against the ships as a provocative move that would eventually lead to war, he ordered the ships to ignore the American blockade. To this President Kennedy responded by saying that the United States was forced into this action after being repeatedly assured that there was no offensive missiles which provided to be a lie The next morning, Kennedy informed the executive committee that he believed only an invasion would remove the missiles from Cuba. However, he was persuaded to give the matter time and continue with both military and diplomatic pressure. He agreed and ordered the low-level flights over the island to be increased from two per day to once every two hours. He also ordered a crash program to institute a new civil government in Cuba if an invasion went ahead. At this point the crisis was apparently at a stalemate. The USSR had shown no indication that they would back down and had made several comments to the contrary. The U.S. had no reason to believe otherwise and was in the early stages of preparing for an invasion, along with a nuclear strike on the Soviet Union in case they responded militarily, which is what they assumed. As the crises continued secret negotiations were taking place constantly between the United States and the Soviet Union, the Soviets wanted the United States to remove its Jupiter missiles from its bases in Turkey as it claimed they pose as much of a threat as their missiles in Cuba. On the other hand the Americans wanted to Russians to remove all missiles and installation that they had placed in Cuba and America would guarantee that it will not invade or offer assistance to anyone who wanted to invade Cuba; it would lift the sea blockage and consider removing the missiles from Turkey. On October 27th 1962, a Lockheed U-2 reconnaissance plane that was flown by Major Rudolf Anderson left Florida to Cuba to take surveillance pictures of the military buildup, and at approximately 12pm, Major Andersons plane was shot down by Russian anti-aircraft missiles, he was instantly killed and was the only casualty from enemy fire during the conflict. This infuriated the Americans, who demanded that the Russians cease all their operations in Cuba and halt any fire; they viewed this as a start of war and took the gesture as an escalation in the violence. Although the commander, who fired, did so by himself, the Soviets were afraid that the Americans would view this as an escalation of war. All Soviet troops were quickly ordered to cease firing on American plane. After the Americans saw no change in the Soviet stance, and the Americans started to prepare for war, they came up with targets to be attacked by air, troops were readied, and plans were made for Cuba including a post-war government, the plans also involved a nuclear strike on Russia in case it got involved. America informed its NATO allies to be ready for an American response and to ready themselves in case the USSR responds in Europe. Ending the Crisis After much consideration between the Soviet Union and Kennedys cabinet, Kennedy agreed to remove all missiles set in Turkey on the border of the Soviet Union in exchange for Khrushchev removing all missiles in Cuba. Premier Khrushchev announced that they were dismantling the missiles in Cuba, while the Americans declared that they would not support or invade Cuba, however they did not mention removal of their Jupiter missiles from Turkey. Because the withdrawals from Turkey were not made public at the time, Khrushchev appeared to have lost the conflict and become weakened. The view was that Kennedy had won the contest between the superpowers and Khrushchev had been humiliated.

Since its inception, Gadhia Solar has been a technologically, solution focused company driven by strong passion for environmental and social contribution combined with high creativity and integrity. The company is into researching and dev eloping new alternatives to harvest the unfathomable source of energy.Automated Steam Jacketed Vessel is a new kind of cooking vessel in itself. The vessels used for soalr thermal cooking are one with direct injection of steam and have limited usability. But with jacketed cooking vessel, any kind of food item can be cooked since the food does not come in contact with the steam. For cooking food, the temperature of the vessel should be maintained in the bracket of 80-120OC which will not only cook the food faster, but also won’t burn it. The vessel was designed with the help of Dr. Vivek Wasekar and for automation of the cooking process; I worked with Mr. Veera Prasad Gadde.For the automation, a Programmable Logic Controller (PLC) is being used which will read the temperature inside the vessel with the help of a Resistance Temperature Detector (RTD) and thereby control the cooking process. Two Solenoid Valves are being used to control the flow of steam and the condensate insid e the jacket. And also a pressure regulator is being used to regulate the pressure of the steam from the header. The parabolic dishes will generate the steam inside the header. When the outlet of the header is opened, the steam at high pressure at around 15 bar will be let into the outlet.The pressure regulator will regulate the pressure of the steam to a value of around 3 bar which will go towards first solenoid valve. When the cooking process is started, the first valve will open and let the steam into the jacketed vessel. The steam will raise the temperature and thereby cook the food. For the initial implementation, three food items have been considered i. e. rice, dal and vegetables. According to the food item being cooked, the controller will decide the temperature and time for cooking and proceed with the cooking. The second solenoid valve will remove the condensate from the jacket of the vessel.Two different loops will be simultaneously controlling both valves till the proces s is stopped or completed.

Introduction: Gadhia Solar Energy Systems Pvt Ltd. has been making Scheffler reflectors for various purposes. The basic idea that leads to the development of the Scheffler- Reflectors was to make solar cooking as comfortable as possible.At the same time the device should be build in a way that allows it to be constructed in any rural welding workshop after a certain period of training. The locally available materials must be sufficient for the construction of the reflector. The movement started when the first well functioning Scheffler-Reflector (size: 1,1m x 1,5m) was successfully built by Mr. Wolfgang Scheffler in 1986 at a mission-station in North-Kenya. Since then the technology has been continuously impro ved and passed on to many motivated people. This lead to the use of Scheffler reflectors in not just cooking but also other applications like VAM, cold storage, etc. For cooking application, these Scheffler-reflectors are used to generate steam in the header pipe.The water inside the header is heated with the reflector and due to the continuous input of heat; steam at high pressure is generated inside the header. When the outlet of the header is opened, this steam at a higher temperature and pressure is used for cooking. A valve is connected to the steam line which goes to the cooking vessel. When the valve is opened, the steam is let into the vessel and hence the food is cooked with it. Gadhia Solar Energy Systems Pvt Ltd has installed many solar cooking systems in India. They have installed the world’s largest solar parabolic concentrated technology systems at Shri Saibaba Sansthan Trust, Shirdi. This system uses the same Scheffler- reflectors to produce steam from water an d uses that generated steam to cook the food.The solar cooking vessels used currently are being operated manually and needs at least one labor per cooking vessel to operate. The cooking is done by direct injection of steam into the vessel. When the food is cooked by direct injection of steam into the food, as the steam is at high pressure and temperature, it comes out of the vessel. Therefore all of the energy of the steam cannot be utilized for cooking. This increases the heat losses and also increases the cooking time. Also due to the type of vessel, it is not possible to cook different types of food. Risk of contamination is also involved if the water source is not clean. So for this purpose a new design of cooking vessel was proposed.This vessel used the energy of steam to heat the food without coming in contact with it. The Steam Jacketed Cooking Vessel Page | 7 was designed to solve the problems which were faced by the earlier used cooking vessel. In this vessel, the steam was being passed in the jacket around the cooking vessel. As the steam condenses inside the jacket, it transfers its heat energy to the food inside and cooks the food. For the Automation of the cooking process, a Programmable Logic Controller is used which will control the temperature inside the cooking vessel and cook the food accordingly. The temperature inside the vessel will be measured by a RTD (Resistance Temperature Detector).This reading will be processed by the PLC as an Analog Input, and according to the food item selected to be cooked, the PLC will select the cooking temperature and time and start the process on user’s command. The process can be controlled by a START button, STOP button, and food type selection button defining RICE, DAL and VEGETABLE for each button. The operator first needs to select the type of food that has to be cooked. According to the selection, respective LED will turn on which will show the food item selected. Even after selecting an item, th e choice can be changed to another food item. After selection, the START button is required to be pressed which will start the cooking.The cooking algorithm will take care of the temperature and the time required for cooking. If the food gets cooked before the timer gets over, or something goes wrong with the process, the operator can manually shut everything down by pressing STOP button. This cooking vessel will increase the types of food that can be cooked with steam. The automation of the vessel will reduce the need of manual labor and will also cook the food faster at optimum temperatures. Page | 8 2. Solar Thermal Cooking: 2. 1 The Scheffler Reflector: The Idea The basic idea that leads to the development of the Scheffler- Reflectors was to make solar cooking as comfortable as possible.At the same time the device should be build in a way that allows it to be constructed in any rural welding workshop in southern countries after a certain period of training. The locally available materials must be sufficient. The Technology To make cooking simple and comfortable the cooking-place should not have to be moved, even better: it should be inside the house and the concentrating reflector outside in the sun. The best solution was an eccentric, flexible parabolic reflector which rotates around an axis parallel to earth-axis, synchronous with the sun. Additionally the reflector is adjusted to the seasons by flexing it in a simple way. How does this work? The reflector is a small lateral section of a much larger paraboloid. The inclined cut produces the typical elliptical shape of the Scheffler-Reflector.The sunlight that falls onto this section of the paraboloid is reflected sideways to the focus located at some distance of the reflector. The axis of daily rotation is located exactly in north-south-direction, parallel to earth axis and runs through the centre of gravity of the reflector. That way the reflector always maintains its gravitational equilibrium and the m echanical tracking device (clockwork) doesn't need to be driven by much force to rotate it synchronous with the sun. The focus is located on the axis of rotation to prevent it from moving when the reflector rotates. The distance between focus and centre of the reflector depends on the selected parabola. During the day the concentrated light will only rotate around its own centre but not move Page | 9 ideways in any direction. That way the focus stays fixed, which is very useful, as it means the cooking-pot doesn't have to be moved either. In the course of the seasons the incident angle of the solar radiation varies + / – 23. 5 ° in relation with the perpendicular to earth-axis. The paraboloid has to perform the same change of inclination in order to stay directed at the sun. Otherwise it's not possible to obtain a sharp focal point. But the centre of the reflector and the position of the focus are not allowed to move. This is only possible by shaping the reflector after ano ther parabola for each seasonal inclinationangle of the sun, i. e. for each day of the year.This means the reflector has to change its shape. The reflector-frame is build for equinox. By inclining and elastically deforming the reflectorframe all other parabolas can be achieved with sufficient accuracy. Changing the inclination and deforming the reflector are mechanically combined: the two pivots, at each side of the reflector-frame, and a pivot in the centre of the reflector, do not form a line, but the second is located below. That way inclining the reflector leads to a change in its depth, the centre of the reflector is lifted up (big radius of crossbars) or pressed down (small radius of crossbars) relative to the reflector-frame.It's enough to adjust the upper and lower end of the reflector to their correct position to obtain a sufficiently exact reflector-shape. The setting is done by a telescopic bar at each end of the reflector. Adjusting the reflector-shape has to be done man ually every 2-3 days. When all concentrated light enters the opening of the cooking-place installed at the focal point the correct reflectorshape is achieved. After passing the opening the light is redirected by a small reflector (secondary reflector) to the black bottom of the cooking pot. There it is absorbed and transformed into heat. The efficiency for cooking, i. e. heating water from 25 °C to 100 °C, can reach up to 57% and depends on the cleanliness of the eflector-surface and the state of insulation of the cooking-pot. At the focalpoint itself we have measured optical efficiency of up to 75% (with 2mm ordinary glass mirrors). Depending on the season an elliptical reflector of 2,8m x 3. 8m (standard size of 8m? SchefflerReflector) collects the sunlight of a 4,3m? to 6,4m? area, measured perpendicular to the direction of the incident light (aperture). That way the cooking power varies with the season. As an average a 8m? Reflector can bring 22 liters of cold water to boili ng temperature within one hour (with 700W/m? direct solar radiation). Page | 10 There are many options for the design of the cooking-place.Mostly it is integrated into a kitchen building and provides the possibility to use firewood for cooking when the sun doesn't shine. Depending on the type of food which is cooked there is no need for a secondary reflector. This increases the efficiency and simplifies maintenance. Instead of a cooking-place a backing-oven, steam-generator or heat-storage can be installed at the focal-point. Page | 11 2. 2 Steam Generation: With the use of the Schefflor Reflectors, steam at high temperature and pressure can be generated with ease. Steam in saturated temperature can be made available at high pressure by concentrating the focus and heating the water in a closed system with the focused heat. The focus of the reflector has to be concentrated onto a receiver of the header pipe.The receiver is painted black to absorb most of the radiation incident on it. The temperature of the focus of a 16m2 Scheffler Reflector can be as high as 700oC and at the receiver it is around 230oC. At such high temperatures, the water inside the header is being heated. Because of the continuous heat supply from the reflector, the water inside the header gets converted into steam. With time, more steam is being generated and pressure inside the header increases. It is possible to get pressure of 15 barg in around 4 hours using four 12. 5 m2 Scheffler Reflectors under ideal conditions and this steam can be used to cook two batches of 25kg of rice. Page | 12 2. Current procedure of cooking: The current procedure for cooking is by direct injection of steam into the cooking vessel. The food cooked by this procedure consists of mainly rice, dal and some vegetables. All of them are cooked in direct steam. First the outlet valve of the header is opened to a little extent. The drain valve at the vessel is opened to remove the condensate. After every cooking sessio n, there is leftover condensate in the steam line. Since that condensate should not come in contact with food, it needs to be drained out first. After the condensate is removed, the condensate valve is closed and the steam is let into the cooking vessel.The cooking vessel contains a predefined amount of water with the food to be cooked. The steam is passed through the mixture, the temperature increases and the cooking starts. Also the operator needs to stir the mixture at regular intervals. In a 100 liters cooking vessel, it takes almost 15 minutes to cook around 28 kilograms of rice. Since the process involves direct injection of steam, the water used reaches the boiling quickly and the food gets cooked faster. But during cooking, after the water has reached its boiling point, a huge amount of steam goes starts to escape the vessel as the vessel has an open lid. This results into loss of a lot of heat energy which could have been used in cooking the rice quickly.When the food gets cooked, the stand of the vessel has a tilting arrangement with the help of which the operator can take out the food from the vessel. So all the valves are closed and then the vessel is tilted to take the food out. The food is not processed after that, it is collected and served directly. Page | 13 2. 4 Current Design of vessel The current design of the cooking vessel is very effective for direct steam cooking. But for the food items which cannot be cooked by steam directly, it is very difficult for the operator to cook such foods. As mentioned the current design uses a direct injection system. The steam from header is carried by the steam line to the vessel where it is regulated with the help of a ball valve.The construction of the vessel is made to facilitate cooking with the help of steam. The vessel’s bottom dish is a regular torispherical dish and it has a shell of same diameter of that of the bottom dish. There is another plate with a defined curvature above the bottom d ish with small holes in it. This plate is for passing the steam into the cooking material. When food is put into the vessel, some predefined amount of water is added with it. So during cooking process, the water gets heated initially and then the cooking starts. Due to direct injection of steam at temperature greater than 100oC, the water reaches boiling point in a short period of time. Thus the cooking process starts.The operator closes the valve when he thinks that the food is appropriately cooked. Figure 1: Previous Direct Steam Injection Cooking Vessel Page | 14 The present design has some benefits, but there is also another side to it. There are some problems with the current design which cannot be rectified without changing the design. The Advantages and Disadvantages of the present design are listed below. Advantages: 1. It facilitates faster cooking time. 2. Since less material is used in manufacture, it saves manufacturing cost. 3. The design is simple which reduces manufac turing time. 4. As it is lighter, it is easier to transport. Disadvantages: 1. There are substantial heat losses during the cooking process. 2.Since the operators cook in an open lid vessel to keep a watch on the food, lot of steam escapes the vessel resulting decreasing the efficiency of process. 3. If the condensed water in the steam line is contaminated, then there are chances of the food getting contaminated. 4. As the outer shell is not insulated, operator has to be cautious or it could lead to injuries. Page | 15 3. Steam Jacketed Cooking Vessel. 3. 1 Designing the Vessel. The design of the vessel was to be made in such a way that it is easy and economic to manufacture. The material chosen for the pilot project of Steam Jacketed Cooking Vessel was Stainless Steel of the grade 304. This material was chosen as it is not affected by steam and it also resists corrosion. The size of the vessel was chosen to be 100 liters.The dimensions of the inner vessel were taken from the existi ng direct steam injection vessel whose volume was 10 liters. Then according to the pressure calculations, the thickness of the sheet and volume of the jacket was defined. The thickness of the vessel is defined as 4mm and volume of the jacket is approximately 1 cubic m for a pressure of 3 barg inside the jacket of the vessel. The vessel is having 3 openings in the outer shell. Two of them are on the horizontal shell and one is in the bottom of the outer dish end. Out of the three openings, one is used for steam injection, one for a safety valve and the bottom one for removal of condensate.All the openings are of 1 inch diameter and will have pipes welded to it for injection of steam, safety valve and condensate removal. The vessel will have two more openings which will be used to mount the RTD and the temperature gauge to measure the temperature inside the vessel. The final drawing of the vessel is shown in FIG 1. Figure 2: Steam Jacketed Cooking Vessel. Page | 16 4. Steam Flow Diagr ams. Water is supplied to the header tank from an overhead tank. Either the overhead tank is at a greater height than that of header, or a sometimes a small pump is used to pump water into the Header. The Solar Concentrators are focused on the receivers mounted on the header pipe.The receivers are painted black to absorb maximum amount of radiation incident on it. These receivers heat the water inside the header and generate steam at higher pressure. This generated steam is vented to the Steam line and the pressure is controlled by the Pressure regulating valve. The solenoid valve SOV1 controls the steam input into the vessel. Thus the temperature inside the vessel can be controlled by controlling SOV1. As the steam is let inside, it will condense after giving its heat. For removal of this condensate, another solenoid valve has been provided SOV2. This valve will remove the condensate at regular intervals. Figure 3: Steam Flow Diagram Page | 17 5.Automation 5. 1 Instruments required . 1. Programmable Logic Controller: A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or nonvolatile memory.A PLC is an example of a real time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result. 2. 2-way ON/OFF Solenoid Valve A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. For this application, two valves will be used. One will be controlling the steam injection into the jacket. The other valve will be taking care of condensate removal from the jacket. 3. Resistance Temperature Detector.Resistance temperature detectors (RTDs) are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it. The RTD element is made from a pure material whose resistance at various temperatures has been documented. The material has a predictable change in resistance as the temperature changes; it is this predictable change that is used to determine temperature. Page | 18 For this application, we will be using a PT-100 RTD with a thermowell.The RTD will be mounted inside the thermowell for its protection from the steam inside the jacket. Thermowell also enables us to change the RTD with ease in case the RTD fails. 4. Pressure Regulator: A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications. Since the header pressure is much more than needed for the application, the pressure will be reduced using a Pressure Regulator. The pressure needed for the application is 3 barg while the header can supply pressure 0-15 barg.To have a steady supply of steam and maintain the pressure and temperature, we will be using a pressure regulator. 5. Temperature Gauge with Thermowell: Temperature Gauge is a device that measures temperature or temperature gradient using a variety of different principles. A Temperature gauge has two important elements: the temperature sensor in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value. A temperature gauge mounted inside a threaded thermowell will be used. Since the temperature reading needed is of the food inside the vessel, the temperature gauge will be mounted on the side of the vessel just like the RTD. The thermowell will protect the Temperature Gauge rom steam inside the jacket of the vessel. Page | 19 5. 2 Logic Diagram: The first diagram displays the logic for controlling cooking process. With turning the device ON, it will start the procedure. According to the outcome of the decision block, it will decide and execute. Figure 4: Logic Diagram for controlling cooking procedure Page | 20 The algorithms given below control the cooking of the food by maintain a specific temperature bracket inside the vessel.  ±3oC range is provided so that the solenoid valves won’t switch ON /OFF at particular temperature which could result in damage. The second logic is for the condensate valve SOV2 which will be ON/OFF at regular intervals.Figure 5: Logic Diagram for controlling cooking and Condensate Valve Page | 21 5. 3 Programming Most of the Programmable Logic Controllers use a different programming language. The language used by them is called Ladder Logic. Ladder logic is a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. It is primarily used to develop software for programmable logic controllers (PLCs) used in industrial control applications. The name is based on the observation that programs in this language resemble ladders, with two vertical rails and a series of horizontal rungs between them.The previously shown logic will be made in Ladder Logic. It will then be downloaded into the flash memory of the Programmable Logic Controller. The PLC will execute the logic and accordingly it will monitor and process the parameters involved. In this project, the opening and closing of both valves and will be monitoring the temperature during the process. The program is made on proprietary software which is supplied by the vendor of the PLC. Every PLC make has specific software which is used to build the program and download the program into the PLC. It can also be used to change the process parameters in online mode. The software also provides offline simulation of the process.For data logging purposes, usually different software is used. The Ladder Logic for the project is under construction and will be finished by the time procurement of all the instruments is done. The parameters which need to be used in the logic will be found out during the processing of the procurement of instruments. During the period of procurement, the manufacturing of the vessel and designing the ladder logic will be done. Page | 22 6. Completed Work and Implementation: From the start, the proj ect has been progressed according to the timeline. Now, all the instruments and material needed for the project has been indented and is in process. Some of the instruments have been dispatched.But for procuring the entire indent, it is going to take some more time. Meanwhile, since the Logic is available, the ladder program is being made and is approaching completion. Also, the manufacturing of vessel is in process and the vessel will be ready by the end of next week. After program is completed, some more time will be given to test it in offline mode and debug the program is any bugs are found. After all the materials are processed and the final values for the process parameters are found out, the project will enter the implementation and testing phase. The entire infrastructure needed for the cooking vessel and the instruments will be constructed on the site.For different types of foods, the values initially found out of temperature and time will be used. If the parameters are not off by some amount, they will be rectified and the control will be made as efficient as possible. During the implementation, various temperature and time readings will be taken. For every type of food item, a detailed sheet should be made which will have all the parameters. According to the observed readings, new and better parameters will be decided which should reduce the cooking time and also increase the efficiency.
