Corn and Pellagra
Corn is a food eaten throughout the world. It is easy to produce and cheap so that in the past it has composed a large part of the diet of the poor who could not afford other foods. The consumption of corn as ones main food source can cause health problems due to a deficiency of the B vitamin niacin that if not treated can lead to insanity and even death. This paper will attempt to present a brief history of pellagra, concentrating primarily on the twentieth century American south, and discussing the causes of the disease, its progression in the human body and treatment.
The first documented description of pellagra was 1735 in Europe by a Spanish physician, Gaspar Casal. He wrote, “Since I never saw a more disgusting indigenous disease, I thought I should explain its characteristics.”(Etheridge 9). Called mal de la rosa, this was a major source of sickness and death among the very poor. In the following years the disease was described many times by Italian physicians and was soon recognized throughout Europe, Egypt, and South Africa. In the early twentieth century it was common in the United States, especially in the south (Roe 1). The disease attacked the poor who were unable to afford only the cheapest diet that had little variety such as meal, molasses, and “fat back” (Harkness 434). Most of these poor were farmers, in the United States it was often found in sharecroppers (Roe 1) or those who lived in industrial communities with little income (Middleton 1209). Statistics indicate that pellagra was the most severe nutritional deficiency disease recorded in United States history (Park et al. 727).
Pellagra is caused by a deficiency of the B vitamin niacin in the diet. Niacin refers to both ni...

In “The Things They Carried” by Tim O’Brien, O’Brien portrays a captivating message of responsibility to his readers. Its moral explains how we sometimes let ourselves “out” of our problems, because we would like to be somewhere pleasant. The excerpt retrospect’s the war in Vietnam and illustrates the mentality and life of the foot soldiers that fought and died there. By establishing what each character carried in a literal, spiritual, and mental form, the reader can understand what the men were about. By doing so, O’Brien creates a world where reality and imagination meet and are in competition with each other.
The Vietnam War holds a different meaning for people both young and old. The longest known US war lasted a solid eighteen years. Some would describe the war as a puzzle since not everyone was for the war. At the age of 21 Tim O’Brien was drafted for the Vietnam War. He states that The Things They Carried is a way for readers to feel what he felt during the war. The key experiences and emotions that he wants the reader to feel are frustration, not being able to find your enemy, having soldiers all around you losing their life, and being upset about being in a war in which you yourself do not believe in. Now forty years later after the Vietnam War first started O’Brien is left with face-less responsibility and face-less grief. He says it best himself “You bring war back home with you. The things you carried in the war are also things you brought back home.”
The case study in regards to the obligation made to the store for the product falls in the realm of promissory estoppel. This is the one exception to the rule requiring consideration, the legal enforcement of an otherwise unenforceable contract due to a party’s detrimental reliance on the contract. Promissory estoppel occurs when three conditions are met and in this case and tin this case all three were met:

The introduction of Old World diseases was a substantial catalyst in the building of American colonial societies. Diseases such as smallpox devastated the native people’s populations. According to one estimate, within the span of the 16th century, the native population of central Mexico was reduced to about 700,000 from at least 13 million. (The Earth and Its Peoples, 475) Other regions were similarly affected by the disease and others such as measles, typhus, influenza, and malaria. These diseases, in effect, cleared the way for European settlers, although, in a somewhat gruesome fashion.

...ke of vitamin b12 or cobalamin levels. Each study presented in this particular article showed that there were several stages in the cause of acquiring the deficiency and in the stage of intake solely through food, the cause of the deficiency were strict vegetarianism without vitamin supplementations. The conclusions similarly show that in each study in this article, the causes were noticeable to be by malabsorption, dietary deficiency and anemia. However contrasted, the studies did not each show that heredity was involved in elderly patients and lack of vitamin B12.
During the early 1600’s colonizing began in America and while more and more Europeans came over so did their diseases, which were uncommon to America. Some of the main diseases were measles, yellow fever and small pox, diseases Native Americans had never came in contact with and could not fight off due to the lack of genetic imm...

A contract is an agreement between two parties in which one party agrees to perform some actions in return of some consideration. These promises are legally binding. The contract can be for exchange of goods, services, property and so on. A contract can be oral as well as written and also it can be part oral and part written but it is useful to have written contract otherwise issues can be created in future. But both the written as well as oral contract is legally enforceable. Also if there is a breach of contract, there are certain remedies for that which are discussed later in the assignment. There are certain elements which need to be present in a contract. These elements are discussed in the detail in the assignment. (Clarke,
A language with rather humble roots, one that has been twisted and bent, one that has taken and borrowed from other languages, and one that has been the subject of much debate as to the correctness of certain usages, today English is the language that the world uses to communicate. The world uses English for a variety of reasons from commerce and trade, to political decisions, to technology and science, and beyond. The entire world uses English to get business done. Thus it truly has become the lingua franca for the world.
It would be reasonable if Honey suggested that English would be the dominant language in the near future. English is still the global language worldwide and the United States is still the driving force in political, economical and cultural fields of endeavor. This dominance will last for a long while yet, but not forever.
One of the last remaining strongholds of classical contract law is the notion that contracts require offer and acceptance therefore, in order for a contract to become binding, offer, acceptance, consideration and intention to create legal relations must exist. However contracts are formed in different ways for each different circumstance. (Shawn Bayern, Offer and Acceptance in Modern Contract Law: A Needles Concept, 103 Cal. L. Rev. 67, 102 (2015)
Over the years English inarguably has reached a status of a global language and commonly is characterized as a lingua franca. It has become the language that is spoken by millions of people all over the world; as the mother tongue, as the language used for international communication and as the language learned in the millions of schools.
