Lactose Tolerance Free Essays

Lactose is the most important carbohydrate in milk. It cannot be absorbed in the intestine, but needs to be split in two molecules by the enzyme lactase. In newborns the (very rare) absence of the enzyme is lethal unless special food can be provided. We will write a custom essay sample on Lactose Tolerance or any similar topic only for you Order Now Until fairly recently it was considered normal by Western medicine that in older children and adults the activity of lactase was maintained. We now know that this is the rule among west Europeans and their descendants in other countries. In many other populations the continuation of lactase excretion in older children and adults is virtually absent, leading to lactose intolerance (Dobzhansky et al., 1997). Lactose intolerance is manifested by diarrhea, abdominal pain, and flatulence after consumption of, let us say, half a liter of cow’s milk (Braly, 1992). This holds for many East Asian groups, Melanesians, Native Americans and for most Africans. Groups of nomadic pastoralists in Africa, such as the Fulani, form a notable exception with high prevalence of lactose tolerance. In southern Europe and in certain regions of India intermediate values (from 30 percent to 70 percent) are found lactose tolerance, a biological, genetic adaptation that is commonly found in populations with a long history of dairying (www.vegsource.com). Populations with this genetic trait have the ability to digest lactose, a sugar found in milk. The intestinal enzyme lactase breaks down lactose into simpler sugars that can be absorbed and metabolized as a source of energy. Lactose also plays a part in the absorption of the calcium in milk. This is especially important when Vitamin D deficiency is present ( Durham 1991:226-228). Durham (1991) has pointed out that the full story is more complicated than was originally supposed, since it involves calcium as well as lactose absorption. Nevertheless, the result is the same. Today, between 70 and 100 per cent of human adults whose ancestors came from long-term dairy-farming areas are lactose-tolerant, whereas the great majority of those who stem from non-dairy-farming areas remain lactose-intolerant. This differentiation must have occurred within the last 10,000 years, and must have been induced by human phenotypes changing their own environments. When the body is functioning normally, lactase breaks down lactose into two simple sugars, glucose and galactose, which are used by the body. But when there is a lack of sufficient lactase, the unabsorbed lactose migrates to the colon, where it becomes fermented by intestinal bacteria and causes gastrointestinal problems. In most humans, lactase activity disappears after infancy. That is, they become more or less lactose intolerant after they are weaned. Although they may be able to drink a small glass of milk without much trouble, if they drink large amounts the undigested lactose gives them diarrhea, bloating, and gas. Even though they do not absorb the lactose in milk as an energy source, they may be able to make use of the protein, calcium, and fat in milk, if they drink small enough amounts to avoid distress and the nutritional losses incurred with diarrhea. Alternately, cultural adaptations such as making cheese or yogurt reduce the lactose content. Presumably, the reason lactose intolerance occurs early in life has to do with the process of weaning. Some children are genetically programmed to stop being able to handle milk once they pass the age of breastfeeding. Although there is no perfect correlation the relationship between lactose tolerance in adults and animal husbandry is striking. Two explanations have been suggested, one cultural, and the other referring to physical qualities of the environment (Flatz Rotthauwe, 1977). In the cultural explanation it is postulated that the consumption of milk, because of its nutritional value in proteins, should give a selection advantage. Once there were a few individuals who can tolerate milk, this trait could slowly spread through the population over a large number of generations. The fact that there are cattle farming populations with a low frequency of tolerance weakens this hypothesis. In addition, when milk has fermented it is low in lactose content and is digestible in the absence of lactase in the consumer’s intestinal tract. The second hypothesis postulates an advantage of lactose tolerance in areas with relatively little ultraviolet sunlight, such as northern Europe. Sunlight plays a role in the production of vitamin D which is needed for calcium metabolism. A too low level of vitamin D leads to rickets, a bone disease. It has been suggested that lactose is an alternative substance to vitamin D in the metabolism of calcium. Another version of this hypothesis bears on the direct absorption of vitamin D contained in milk and milk products. In practical terms, knowledge of lactose tolerance and intolerance is important when proposing food aid programs. Knowing that milk can cause digestive problems helps us understand why recipients of powdered milk as emergency aid have used the milk to whitewash their buildings and have even accused aid programs of being U.S. plots to poison them ( Lerner and Libby 1976:327). Health educators also need to be cautious about over-promoting milk products to ethnic groups, such as Asian Americans, who do not tolerate them well. In evolutionary terms, farming is quite recent on the human scene, and most of the adaptations to it have been cultural rather than genetic. Lactose tolerance is particularly interesting because it shows the coevolutionary interaction between biological and cultural adaptation to the farming way of life. References Attwood, Charles R.

Glass Menagerie Symbolism of the unicorn Essay Example For Students

Glass Menagerie Symbolism of the unicorn Essay The symbolism of the unicorn has two very different meanings. One of the symbols is happiness and love. The other one symbols sadness and hatred. You first come into contact with the unicorn when Jim sees it. This is where the first symbolism comes into place. Once Laura starts to talk about it you can sense a feeling of happiness once they really get into their conversation. They start to talk about there past, which included Blue Roses. Once Jim called Emily Meisenbach a kraut-head, Laura knew there could definitely be something between them two. Jim had been telling Laura to have more confidence and to dont think of yourself to be crippled because you arent. You are beautiful. Sparks are really flying until Jim hears some music from the Paradise Dance Hall across the ally and asks Laura to dance. This is where the second symbolism comes into place. As they start to dance Jim hits a table where the unicorn was put. The horn of the unicorn broke off. Jim felt so bad that he told her he should be going. Laura asked when will you come back. Thats when it all fell apart. Jim told Laura that he was going steady with another girl called Betty. Laura was shocked, but didnt want to say anything. Anything that was between Jim and Laura was gone. Nothing was left. Jim left after telling Amanda and thats how the play ended. As you can see, the unicorn played an important role in the play even though it didnt seem as though it would. This is a very well put deception by Tennessee Williams showing his greatness in the art of play writing.

The Road Not Taken By Robert Frost Essay Example For Students

The Road Not Taken By Robert Frost Essay Robert Frost is the most well known American poet who draws on nature as a subject for his poems. Nearly all of his poetry can be related to the outdoors and a free feeling that Frost seems to cherish. This also was reflected in his life as he lived around nature for the majority of his life. It is not hard to see through his poems how deeply moved he is by the Earth and the miracle of life. He did suffer through an array of hardships during his life, but still kept an appreciation for what he still had. Robert Lee Frost was born in San Francisco on March 26, 1874. His father, William was a Harvard educated journalist who worked for the Daily Evening Post and was elected as a delegate to the Democratic National Convention in 1880. Isabelle, his mother moved to America at the age of 12 as the daughter of a Scottish sea captain. His mother was his primary source of education and home schooled him for much of his early life. His father passed away in 1884 from tuberculosis and his mothe r moved him and his sister to Lawrence, Massachusetts. This is the first time that Robert is really close to nature and he begins his love for the outdoors here. The basis of our government was realized by Lord Acton, a British historian when he wrote, Power tends to corrupt, and absolute power corrupts absolutely. He knew that if any one person or group ran a country, they would soon become power crazed and lose the respect and support of its citizens. This is the reason why our forefathers came up with a system of checks and balances to ensure that no one group could control the entire government. Lord Acton was not the first to believe in a separated government. Philosophers dating back to Aristotle favored a government that contained the elements of monarchy, aristocracy, and democracy. John Locke later wrote that the best way to eliminate corruption in government was to separate the powers of the legislative and executive branches. Montesquieu added the powers of the judiciary branch to complete what we now call separation of powers. Our forefathers only had to refine the philosophers ideas to come up with our present system of government. Basically they wrote that the executive branch enforces the laws, the legislative branch passes the laws, and the judiciary branch interprets the laws. The president runs the executive branch. The president has many powers including the right to veto a bill. If Congress passes a bill, the president can veto it and unless each house has a two-thirds vote to override the veto, the bill never becomes a law. Over the history of our government, presidents have vetoed over 2,500 acts of Congress and been overridden over 100 times. The president can also call Congress into a special session if they do not act upon proposed legislation by the president. Since the president is head of a political party he can easily influence Congress into legislation. The president can appeal directly to the public in order to influence Congres s. Presidents also have a unique power to pardon people who have been convicted of federal crimes. Another task of our president is to begin the process of appointing all federal judges and other officers of the government, such as his cabinet, ambassadors, ministers, and consuls. Before these positions can be appointed Congress also has to approve each of the officers who were elected by the president. All Supreme Court Judges have been elected by the president then approved by Congress before being appointed. The relationships of the United States and other foreign countries are mostly determined by the president He has the power to decide whether to recognize new nations and governments, and in turn to negotiate treaties with them. He cannot however do this alone. He is dependent on the Senate to approve the treaties with a two-thirds vote. The Senate does not always need to approve the negotiations with foreign nations. The president can negotiate executive agreements without ha ving to be approved by the Senate. .u24a55148d687b6599dad61417bf19bf3 , .u24a55148d687b6599dad61417bf19bf3 .postImageUrl , .u24a55148d687b6599dad61417bf19bf3 .centered-text-area { min-height: 80px; position: relative; } .u24a55148d687b6599dad61417bf19bf3 , .u24a55148d687b6599dad61417bf19bf3:hover , .u24a55148d687b6599dad61417bf19bf3:visited , .u24a55148d687b6599dad61417bf19bf3:active { border:0!important; } .u24a55148d687b6599dad61417bf19bf3 .clearfix:after { content: ""; display: table; clear: both; } .u24a55148d687b6599dad61417bf19bf3 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u24a55148d687b6599dad61417bf19bf3:active , .u24a55148d687b6599dad61417bf19bf3:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u24a55148d687b6599dad61417bf19bf3 .centered-text-area { width: 100%; position: relative ; } .u24a55148d687b6599dad61417bf19bf3 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u24a55148d687b6599dad61417bf19bf3 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u24a55148d687b6599dad61417bf19bf3 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u24a55148d687b6599dad61417bf19bf3:hover .ctaButton { background-color: #34495E!important; } .u24a55148d687b6599dad61417bf19bf3 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u24a55148d687b6599dad61417bf19bf3 .u24a55148d687b6599dad61417bf19bf3-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u24a55148d687b6599dad61417bf19bf3:after { content: ""; display: block; clear: both; } READ: Herman Melville And Moby Dick Essay We will write a custom essay on The Road Not Taken By Robert Frost specifically for you for only $16.38 $13.9/page Order now The Congress, which runs the legislative branch is made up of two houses, the Senate and the House of Representatives. The Senate contains two officials elected from each of the fifty states and population determines the number of officials in the House. This means that the more densely populated states have a higher number of representatives. Congress is where amendments and bills are first voted on. In the case of the president vetoing their proposed bill, the Congress can vote again and with a two-third majority still pass the bill. It then passes through to the Supreme Court, which is the last stop for a proposed bill. It is there that the judges determine whether the new bill is Unconstitutional and if so the bill is not passed. In all 155 congressional acts have been deemed by the Supreme Court to be Unconstitutional. The federal budget has to be approved by the Congress. All revenue bills must originate in the House then be approved by the Senate. This is to ensure that the St ates with larger populations cannot control the money situation. In fact any bill that is passed by one house can be voted against in the other. With a majority, that bill will not be passed through for the presidents approval. The Senate also has a few powers that are reserved strictly for them. Only the Senate has to approve the presidents choice for government officials and ambassadors. Only nine cabinet nominees have ever been denied by the Senate. They are the only house needed to ratify treaties that are proposed by the president. In the matter of impeachment both houses have powers that they can call their own. The House has to bring charges of misconduct and then the Senate tries the cases and determines whether they are guilty or innocent. Both houses of Congress have shared responsibility for economic decisions including taxes, borrowing money, regulating commerce between states and with foreign countries, making money and stating its value, punishing counterfeiters, and d etermining bankruptcy laws. In addition the houses determine the rules and regulations for the naturalization of foreign citizens, set the standard for weights and measures, provide for post offices and public roads, issue patents and copyrights, punish piracy, and establish federal courts. They also provide for an army and a navy and can declare war. They can use these military forces in order to uphold our laws. The final branch of our government is called the judiciary branch. It is made up of both the federal and state court systems. There were state courts long before the Constitutional Convention, which brought up a debate on whether we should even have a federal court system. They soon decided that we should keep the state courts and add a federal court system with limited power. The first Congress then divided the country into districts and created a federal court for each one. The federal court system now consists of the Supreme Court, 91 district courts, 11 appeals courts, and three courts of special jurisdiction. In order to become a federal justice one has to be nominated by the president then approved by the Congress. Judges are not elected for a certain number of years; instead they hold their positions during good behavior. This simply means that until they die, retire or resign they remain in office. If a judge ever commits an offense they can be impeached by Congress and lose their job. Congress carries even more power over the federal court system. Congress can create or abolish any federal court besides the Supreme Court. It also determines how many judges are used in the judiciary system and what their pay scale is. .ue4b618f73c6b64edc90ed7efa5ba0cd1 , .ue4b618f73c6b64edc90ed7efa5ba0cd1 .postImageUrl , .ue4b618f73c6b64edc90ed7efa5ba0cd1 .centered-text-area { min-height: 80px; position: relative; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 , .ue4b618f73c6b64edc90ed7efa5ba0cd1:hover , .ue4b618f73c6b64edc90ed7efa5ba0cd1:visited , .ue4b618f73c6b64edc90ed7efa5ba0cd1:active { border:0!important; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .clearfix:after { content: ""; display: table; clear: both; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue4b618f73c6b64edc90ed7efa5ba0cd1:active , .ue4b618f73c6b64edc90ed7efa5ba0cd1:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .centered-text-area { width: 100%; position: relative ; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue4b618f73c6b64edc90ed7efa5ba0cd1:hover .ctaButton { background-color: #34495E!important; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue4b618f73c6b64edc90ed7efa5ba0cd1 .ue4b618f73c6b64edc90ed7efa5ba0cd1-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue4b618f73c6b64edc90ed7efa5ba0cd1:after { content: ""; display: block; clear: both; } READ: Scarlet Letter And Scaffold EssayJudicial power is used in many different sorts of cases.

The Search for Meaning in Slaughterhouse Five essays

The Search for Meaning in Slaughterhouse Five essays Kurt Vonnegut's novel Slaughterhouse Five represents a man's desperate, yet, useless search for meaning in a senseless existence. Vonnegut uses a narrator, which is different from the main character to develop his theme. Vonnegut introduces Slaughterhouse Five in first person point of view. In the second chapter, however, this narrator changes to a bystander who speaks from a third person perspective. Vonnegut wants the reader to realize that the narrator and Billy Pilgrim, the main character, are two different people. In order to do this, Vonnegut places the narrator in the text, multiple times. An American near Billy wailed that he had excreted everything but his brains...That was I. That was me.? This statement clearly illustrates that the narrator and Billy are not the same people. The narrator was the American disgusted by Billy. Vonnegut places his experiences and his views in the text. He begins the book by stating, "All this happened, more or less." The war parts, anyway, are pretty much true...I?ve changed all of the names.? He feels war is a senseless act and, Slaughterhouse Five allows Vonnegut to express his feelings on the matter. Through Billy Pilgrim, he is able to portray his views. They had been lying in ambush for the Germans. They had been discovered and shot from behind. Now they were dying in the snow, feeling nothing, turning the snow the color of raspberry sherbet. So it goes.? He uses vivid and meaningful imagery here. The reader can picture the snow slowly being colored with the blood of the soldiers. By ending with the statement,So it goes,? The reader is satisfied. Vonnegut uses this statement throughout the book to show that death is death, there is no glorious or great death; all death is equal. Vonnegut doesn't want to glorify war. The narrator made a vow to O?Hare's wife , in chapter one, that the story would not do this. ...I give my word of honor. I'll call it the children's crusade.? ...

Personal Development - Essay Example In addition, some level of qualitative research will be conducted to determine real-life attitudes of currently-practicing nurses and administration (where appropriate) to determine what credentials or habits would be best-suited to an administrative nursing role. I believe these practices will enhance my knowledge of the nursing profession by being able to link theoretical nursing theory with tangible practice dynamics. As part of my vision for excellence in holistic nursing practice, servant leadership and transformational leadership will be critical to becoming a well-rounded nursing professional able to take a solid leadership position in a dynamic health environment. Servant leadership demands having a focus on others, providing empathetic and benevolence toward others while still developing my own professional competencies (Farazmand et al., 2010). Servant leadership demands being altruistic in virtually dimensions of practice, creating a global perspective that recognizes dive rsity of culture and non-biased servitude for a variety of different patients and professionals. Transformational leadership is also critical for becoming a Chief Nursing Officer as this requires the ability to establish followership, team performance and loyalty from subordinates. Fairholm (2009) describes transformational leadership as being inspirational, while setting a vision for team practice, and then routinely conveying this vision through role modeling and constant communication with team members. Transformational leadership requires the nurse to be a teacher and coach, helping others to develop their own competencies and, ultimately, self-actualization at the psychological level. Transformational leadership provides local-level leadership within the microeconomic health care environment. I must also be considerate of my own personal needs as a professional in this field. I have conducted several self-analyses regarding my preferred learning styles, personality type and lea dership characteristics. These assessments and evaluations have returned very consistent results that indicate I am well-suited for a servant leadership role, maintaining considerable empathetic characteristics and high emotional intelligence. An effective leader in a highly-visible nursing role in administration must be able to gauge the emotional states and needs of their followers and patients in order to provide effective care. At the same time, I must be equipped to regulate my own emotional responses in professional meeting environments, when dealing with disheartening patient scenarios, and when working with diverse cultural representatives. Personal satisfaction will come by finally being self-actualized in relation to my very legitimate desire to assist others in need. Personal satisfaction will also be achieved by having a dominant role in the organization, which tends to suit many of my personality characteristics. Based on honest self-assessment and the results of many d ifferent evaluation tests, I have many dominant characteristics when it comes to leadership, both socially and professionally. I am very self-confident about my abilities and my problem-solving competencies and therefore I trust in my

Writer's Chioce Movie Review Example | Topics and Well Written Essays - 1250 words

Writer's Chioce - Movie Review Example For instance, the movie depicts the overflowing of Manhattan as a wind-caused surge, even though this epic wave, which is also known as tsunami could only be stimulated by a marine earthquake or tremor or a meteorite strike, rather than by a hurricane or an alteration in the North Atlantic Current. The stun frosting in the view of the hurricane goes against the laws of thermodynamics (Rehill, 2009). The filmmakers are honest about the truth that it is not a precisely realistic scenario. The promotion material given by the film firm Fox says that once scientists converse about sudden climate change they imply ten or five years, but for theatrical reasons, the whole thing was condensed to a couple of weeks. In order to depict the dramatic impacts of a vital climatic catastrophe in a short time span, they only took acknowledged weather limits such as storm surges, tornados, hailstorms and cyclones blizzards. Conversely, given the constraints and rules of the genre, it is astonishing to what level the filmmakers have attempted to include some sensible background. For instance, in the early moments of the film, the director reveals a United Nations climate convention in Delhi where Jack Hall talks about the probable risk of a blackout of the North Atlantic Current (Ebert, 2005). During the convention, Jack Hall states that a blackout may occur in a thousand years or hundred years, or may not at all. Several real climate experts have said a similar thing. In this manner, the actor shows what climate experts think in a realistic way in the movie. The director of the movie shows the politics of weather change. It is disturbingly realistic how the leader of the United States delegation, who is the vice president in the movie, reacts to Halls speech. This implies that small prospects with few words of dialogue are smartly used to initiate a number of key conflicts and ideas, which are extremely recognizable to climatologists but not

Mongolia Tourism Article Essay Example | Topics and Well Written Essays - 1250 words

Mongolia Tourism Article - Essay Example The outcomes of the study were utilized in making recommendations to the Mongolian tourism authority on efficient targeting of its international tourism market and improvement of tourism services in the country. 2. A number of factors have influenced the growth of international tourism in Mongolia. The collapse of the eastern European communism system, poor economic conditions, forest fires and adverse weather conditions made international tourism in Mongolia to deteriorate between 1990 and 1997. Business activities brought tourists from China and Russia Federation across Mongolia and this led to a sharp improvement in Mongolian international tourism in 1998. Other factors that improved tourism in Mongolia include favorable visa regulations that enabled tourists to get visas at the Mongolian border. The National Tourism Board that was promulgated in 1995 helped market Mongolia as a favorable tourism destination. Businesspeople from Korea and Japan who worked in Mongolia spread news back in their home countries about Mongolia. The internet helped raise awareness about Mongolia, increased accessibility to travel advertising and reservations and made them less costly. The good impression that Mongolia created in its early Japanese and Korean visitors was another factor in the improvement of tourism in the country (Yu & Goulden, 2006). 3. Cognitive dimension is one of the constructs through which tourism satisfaction can be viewed. The dimension entails tourists’ experience with services. Tourists’ reaction to service performance is captured in the affective dimension of tourism. Systemic dimension of tourism articulates the disparity between the services that tourists expect and things that they get while on the ground. The cross-cultural dimensions of tourism emphasize the impact that cultural difference has on tourists’ perception of service delivery and quality. The dimension reckons that the difference between the
