Schools of Thought Regarding the Future of America essays

Schools of Thought Regarding the Future of America essays Schools of Thought Regarding the Future of America Three schools of thought appear to dominate considerations regarding the possible future of the United States of America. These include declinism, American exceptionalism, and neoimperialism. Only time can tell which is the most likely outcome. Realistically, and if history is taken into account, it appears that declinism enjoys favor over the other two possibilities when applied to the American situation. According to declinism, all great nations enjoy a period of greatness, after which they decline. This decline can be blamed on many factors, and often the causes include more than one aspect of the political and social fabric of the once great nation. Declinists hold that the same is true of the United States. The terrorist attacks and subsequent international climate in relation to the United States appear to substantiate the declinist view. The United States have become very powerful and this may have led to a paradigm of unmerited confidence in security and other systems that in fact were not up to standard. The ease with which the September 11 attacks occurred seems to substantiate the lack of security systems. Historically also declinism seems to be the norm for once great nations such as Rome and England. American exceptionalism is the contrasting view to declinism. According to this belief, the United States is unique in its strengths, and shares none of the weaknesses of its once great European counterparts. Thus, the United States is not only great in itself, but also offers opportunities for humanity as a whole. According to this view then, the history of England and Rome is not applicable to the United States, because of the latter's unique qualities. One of these unique qualities setting the country apart from its historical counterparts is its religious ...

Therefore, Air France need to concentrate on identifying the correct words and drop some of the keywords that have no search requests or have below per requests. Customers will normally search the keywords and in the event that they do not find what they want with the first click, most of the will not move to the next page or rephrase the keywords they are searching for (Robinson, Lindsey and John, Pg. 10). The campaign tactics should be adjusted so that they focus more on the correct keywords rather than the number of

Gender Stereotypes Essay Example for Free

Gender Stereotypes Essay Simply put, gender stereotypes are generalizations about the roles of each gender. Gender roles are generally neither positive nor negative; they are simply inaccurate generalizations of the male and female attributes. Since each person has individual desires, thoughts, and feelings, regardless of their gender, these stereotypes are incredibly simplistic and do not at all describe the attributes of every person of each gender. While most people realize that stereotypes are untrue, many still make assumptions based on gender. There are many stereotypes we may all be guilty of, such as assuming that all women want to marry and have children, or that all men love sports. The following is a list of some of the most common gender stereotypes as they pertain to either men or women. Remember that these are stereotypes because they claim to apply to all men or women. Female Gender Stereotypes Gender stereotypes begin the second a baby’s gender is found out. As soon as we find out it’s a girl, we immediately begin decorating a pink nursery filled with soft dà ©cor and butterflies and flowers. We assume that our daughter will be very girly and fill her closet with frilly dresses and her toy box with tea sets and dolls. What this is essentially doing, even though many parents don’t realize it, is setting our child up to be the perfect lady, and teaching her how to be the stereotypical woman. We are teaching her that girls are supposed to wear dresses, serve food, and take care of babies; the biggest and most common stereotype put on women. Have you ever watched a little girl playing house? Even as young as five or six, she is well aware that she is supposed to stay home with the baby while the husband goes to work, and she has dinner ready when he gets home. Here is another stereotype; women stay at home while men go to work. While there are a million gender stereotypes about females, these are definitely the biggest, and the most debated by feminists of today. Some other stereotypes include: Women are supposed to have clean jobs such as secretaries, teachers, and  librarians Women are nurses, not doctors Women are not as strong as men Women are supposed to make less money than men The best women are stay at home moms Women don’t need to go to college Women don’t play sports Women are not politicians Women are quieter than men and not meant to speak out Women are supposed to be submissive and do as they are told Women are supposed to cook and do housework Women are responsible for raising children Women do not have technical skills and are not good at hands on projects such as car repairs Women are meant to be the damsel in distress; never the hero Women are supposed to look pretty and be looked at Women love to sing and dance Women do not play video games Women are flirts Women are never in charge Male Gender Stereotypes Stereotyping is no different when it’s found out that a boy is on the way. The nursery is decked out in blue, his closet is filled with tiny jeans, polo shirts, and boots, and the theme is usually something like jungle animals or dinosaurs; something tough. Boys’ toys consist of trucks, dinosaurs, action figures, and video games. From the beginning boys are taught to be tough, to be protective, and to defend themselves. Boys are taught that daddy’s go to work and mommy’s stay at home; from their point of view, boys have fun and girls do all the work. Are you surprised to hear that most parents admit that they do not teach their sons how to do chores such as washing dishes or folding laundry? Instead, they teach them to take out the trash and mow the lawn; from the get-go boys are made to think that certain household chores are women’s work. This is a major stereotype, but the majority of American households  today would prove this to be true. Men are supposed to do the dirty jobs and anything that requires muscle, they are also supposed to go to work and provide for the family. Little boys see this and the stereotype continues. Other gender stereotypes that inaccurately try to describe all men are: All men enjoy working on cars Men are not nurses, they are doctors Men do dirty jobs such as construction and mechanics; they are not secretaries, teachers, or cosmetologists Men do not do housework and they are not responsible for taking care of children Men play video games Men play sports Men enjoy outdoor activities such as camping, fishing, and hiking Men are in charge; they are always at the top As husbands, men tell their wives what to do Men are lazy and/or messy Men are good at math It is always men who work in science, engineering, and other technical fields Men do not cook, sew, or do crafts Can you see how many of these actually are true of many men or women that you know? They may even be true for you personally, but they do not apply to every single man or woman alive. That is what makes them stereotypes; the fact that these things are considered, the norm and expected of every male or female. Each person is an individual and it is perfectly normal for a woman to run her own business while a man stays home with the kids. On the other hand it is also perfectly acceptable for a man to be a nurse or hate sports, or enjoy cooking. Men and women are individuals; they are more than just male or female. Our gender is only part of who we are; it does not define us as people.

Charlotte Temple Essay :: essays research papers

The Tabloid of the Century (1800’s -1900’s) The general reason I think Charlotte Temple stayed on the best seller list for so many years is because the subjects that were discussed in the book were taboo in that day and time. Montraville was a soldier in the army who was about twenty three years old, and Charlotte was only fifteen. He was much older than Charlotte. Montraville influenced her in evil ways; he impressed her with his knowledge of love and the world by writing her a letter and giving it to her personally . Montraville knew this was forbidden but gave it to her anyway. " Tis a romantic attempt," said he,"and should I even succeed in seeing and conversing with her, it can be productive of no good: I must of necessity leave England in a few days and probably may never return; why then should I endeavor to engage the affections of this lovely girl, to leave her prey to a thousand inquietudes, of which at present she has no idea? I will return to Portsmouth and think no more about her"( Rowson 11 ). Montraville went against his judgment. He knew that her parents would be angry if they knew that their daughter was having a relationship with a man! He was supposed to be a responsible soldier: an honorable man that would not do this kind of thing! But he would continue to see her. He even paid her guardian so she would keep bringing her to see him. " He soon pund means to ingratiate himself with her companion, who was a French teacher at the school, and, at parting, slipped a letter he had written into Charlotte’s hand, and five guineas into that of Mademoiselle, who promised she would endeavor to bring her young charge into the field again the next evening" (Rowson 11). Montraville was influenced himself by Belcore who was evil. When Montraville and Charlotte would meet, he would bring Belcore along to entertain Charlotte’s guardian, La Rue. "...he had wisely brought Belcore with him to entertain Mademoiselle while he could have an uninterrupted conversation with Charlotte. ... Belcore... possessed a genteel fortune and had a liberal education; Dissipated, thoughtless, and capricious, he paid little regard to the moral duties, and less to religious ones: eager in the pursuit of pleasure, he minded not the miseries he inflicted on others, provided his own wishes, however extravagant, were gratified.

Why same-sex marriage should be legal

Why same-sex marriage should be legal. BY aurore1997 Ladies and gentlemen, good morning. Here we are today about to debate whether or not individuals in love with each other should be able to get married or not. Yet twelve years and 3 months is the time that has passed since the first homosexual marriage was made official in a Canadian province. Since 1996,because of the Defense of Marriage Act which prevented-and still does- homosexual couples from receiving benefits traditionally conferred by marriage ; states have scrambled to efine their own stance on the issue.The restriction of marriage to heterosexual couples should be abolished because it is discriminatory to homosexual couples. Most conservatives use Christianity as a backup for their argument. But unlike what they may all think, homosexuality is not a sin. It is a strong tendency ordered towards a moral evil, you may want to discuss this point but it was said in a Vatican letter in the year 1986. Under the papacy of his hol iness John Paul II. There's absolutely no eason of principle that emotional union should be restricted to heterosexual couples.Nor are there any constitutional reason,in fact the act that ‘defines' marriage to be the union of a man and a woman was proven unconstitutional. As it goes against the tenth amendment of the United States constitution. We believe that our society is open-minded but the issue of gay marriages proves us wrong. Homosexuals are called perverts by the majority of the world population. People that are supposed to set examples do not, in February 2004, a Belgian cardinal publicly aid that he would not open his door for any homosexuals because they are sexual perverts.They are not perverts, they are sensitive humans like you and me , they just have a different sexual orientation, in fact a recent study proved that homosexuals rate their relationship more favorably than heterosexuals do and the average homosexual relationship lasts longer than the average hete rosexual relationship. According to this study they ‘know how to love' better than heterosexuals do. Despite all these factors, people still dare to call homosexuals perverts Just because they are the minority.Is this not similar to racism ? In my opinion it sure is. Regarding the Belgian cardinal harsh words,a Vatican spokesperson said, â€Å"People with a homosexual inclination must be accepted with respect,compassion and sensitivity†. Homosexuals feel more accepted after the marriage according to a survey. They also observed that people give more credibility and less perversity to their relationship when they are officially and legally arried.We observed through bullying that what society feels about you can make you feel confident but it might as well push you to suicide. Refusing to legalize homosexual marriage gives the right to society to mock homosexuals and to exclude them because they are different. Exile leads to depression and to suicide in most cases. Do we want more unnatural deaths in this country ? I am sure we do not. The restriction of marriage to heterosexual couples should be abolished because it is discriminatory to homosexual couples.

Oh captain my captain Essay

â€Å"O Captain! My Captain!† is a poem written by Walt Whitman in 1865. The poem is classified as an elegy because it is a mourning poem that was written in the memory of someone. The poem was written to honor Abraham Lincoln, the 16th president of the United States. Walt Whitman was born in 1819 and died in 1892, so he lived through the American Civil War. Being born close to the founding of the country, he knew people that were a part of the American Revolution. Through this he experienced the unification and division of the United States. Walt Whitman was extremely patriotic and wrote many poems about the prominence of America. He also wrote poems about urging people to fight for what is right. The poem was known as one of the greatest poems written at the time of the Civil War. The main political and social issue during Whitman’s time was slavery and the rights of African Americans. Whitman was self-described as the poet of America and, during the Civil War, the Un ion. Whitman wanted to see the end of slavery; this was his hope for America. However, it broke his heart to see the nation fighting. He admired Abraham Lincoln immensely because of his political standpoint of universal equality as stated in the constitution. The captain in the poem refers to Abraham Lincoln who is the captain of the ship; this represents the United States of America. The first line establishes a happy mood as it addresses the captain. The phrase â€Å"our fearful trip is done† is talking about the end of the Civil War. The next line references the ship, America, and how it has â€Å"weathered every rack†, meaning America has braved the tough storm of the Civil War, and â€Å"the prize we sought†, the end of slavery, â€Å"is won†. The following line expresses a mood of jubilation of the Union winning the war as it says â€Å"the people all exulting†; however, the next line swiftly shifts the mood when it talks of the grimness of the ship, and the darker side of the war. Many lost their lives in the American Civil War, and although the prize that was sought was won, the hearts still ache amidst the exultation of the people. The repetition of heart in line five calls attention to the poet’s vast grief and heartache because the Captain has bled and lies still, cold, and dead (lines six through eight). This is no doubt referencing the assassination of Abraham Lincoln and Whitman’s sorrow for the death of his idol. In the second stanza the speaker again calls out to the Captain in a light-hearted manner and dictates to â€Å"rise up and hear the bells†, to join in on the celebration of the end of the war. The next three lines tell the  captain to â€Å"rise up† and join in on the revelries because it is for him. He is the reason for their merriment: â€Å"for you the flag is flung—for you the bugle trills; for you bouquets and ribbon’d wreaths—for you the shores a-crowding; for you they call, the swaying mass, their eager faces turning†. Everyone is celebrating what Lincoln accomplished; this is not only the abolishment of slavery but also the format ion of the Union and the coming together of people. Again the poet calls to the Captain as if he had never fallen. The poet does not wish to acknowledge the death of his beloved Captain, and he even asks if it is some dream (line 15) that the Captain has fallen â€Å"cold and dead†. The third stanza begins in a somber mood as the poet has finally accepted that the Captain is dead and gone. Here there is vivid and darker imagery such as â€Å"his lips are pale and still† and the reader can picture the dead Captain lying there still and motionless with â€Å"no pulse nor will†. In line 17, the poet calls out â€Å"My Captain,† and in line 18, the poet refers to the Captain as â€Å"My father†. This is referring to Lincoln as the father of the United States. Lines 19 and 20 are concluding statements that summarize the entire poem. The United States is â€Å"anchor’d safe and sound†. It is safe now from war with â€Å"its voyage closed and done, from fearful trip, the victor ship, comes in with object won†. The country has accomplished its goal of the abolishment of slavery and the unification of people after a fearful war. In line 21, the examples of apostrophe, ordering â€Å"shores to exult,† and â€Å"bells to ring† are again referring to how the nation is celebrating while â€Å"I with mournful tread, Walk the deck my Captain lies, Fallen cold and dead†. Throughout the paper there is a distinct rhyme scheme, which is unusual for Whitman. The rhyme scheme in â€Å"O Captain! My Captain!† is AABCDEFE, GGHIJEKE, and LLMNOEPE for each stanza respectively. Two examples of alliteration are in line 10 â€Å"flag is flung†, as well as in line 19 â€Å"safe and sound†. Repetition occurs many times in this poem, for example â€Å"O Captain! My Captain†, and â€Å"fallen cold and dead†.

Lab Report Topics #038; Ideas

Lab Report Topics #038; Ideas The main purpose of a laboratory report is to describe the findings obtained during the laboratory research. Laboratory experiments are practiced in a wide range of educational institutions that are focused on exact sciences. Taking into account the fact that all hard sciences are natural and, consequently, are characterized by clarity and consistency, the laboratory reports have to be objective and draw on the existing scientific concepts. Such an analysis is predominantly carried out on the basis of the hypothesis that can be justified or refuted during the study process. Choosing a topic and writing a laboratory report is a remarkably challenging task for the overwhelming majority of students due to the particular complexity of the exact sciences. Understandably, the issue of the paper depends on a specific science directly, but it does not abolish the existence of a considerable number of subjects for each of the exact sciences. Given such a wide choice of research, the topic should be not only correlated with the task of a particular discipline but also be a subject of curiosity for the student. Furthermore, the report requires a logical approach, critical thinking, impartiality, and maximum accuracy. Topics and Ideas for Lab Report Spatial Processing of Signals within Digital Shortwave Radio Systems The issue of spatial signal processing within the shortwave range is significantly underestimated and insufficiently investigated due to the complexity of the details in the frequency range. This topic should analyze the basic possibilities of using the spatial adaptation of radio communication channels by implementing a unique set of methods of spatial signal processing. The report can include the practical application of this signal-processing tool, the allocation of methods for adaptation of communication channels to the modern environment, and the evaluation of the efficiency of shortwave bandwidths. Statistical Methods in Medicine Although the use of statistic methods in the field of medicine is a relatively new approach, statistical evaluation of data is rated significantly high within the framework of the treatment process. This method of clinical research, which is known as biostatistics, has fundamentally changed the entire healthcare industry. The lab report has to focus on the description of the transition of medical research from the summary of individual observations to experimental work using control groups and large-scale trials, its paramount importance for the development of the science of medicine, and value for both patients and doctors. Development of Acoustic Systems Taking into account the speedy development of technologies, acoustic systems are the primary means of high-quality sound reproduction. Moreover, its application both in domestic and in production conditions increases its significance largely. This work can focus on the analysis of the purpose and composition of the product depending on the environment and its conditions, the technology of making the device, and its essential elements. Besides, this study will help to achieve maximum design efficiency for market promotion. Projection of Alternative Energy Sources Alternative power generation technologies have become not only extremely popular in the twenty-first century but have all the chances to take a niche of traditional sources. In order to examine this type of energy production thoroughly, the report can describe the use of this source within a specific country, region, or town, and analyze the favorableness of particular territory for the purpose of alternative methods. Examining the obtained data it is possible to analyze the energy efficiency of the implementation of this method and determine the most appropriate type, that is, solar, wave, biomass, geothermal, tidal or wind energy. Production of Straw Panels for Eco-Friendly Houses Straw is a great building material for construction energy efficient and environmentally friendly houses. This material is created without any chemical elements, which makes its cost considerably lower than usual building materials. The lab report may include comparing the thermal conductivity of straw with other materials such as gypsum or ceramic based on which one can prove or refute the economic feasibility of this product. Besides, such information may be useful for commercial enterprises which want to be involved in this area but not sure about the profitability of such a business. Computer Modeling of Body Movements under the Influence of Gravity Computer modeling is applied today in all spheres of sciences without exception. It not only allows one to investigate a particular issue more profoundly but also demonstrates it visually. Such a method is particularly useful for the study of physics. This report can take a variety of bodies moving in outer space as a basis and trace the influence of gravity on each of them. The acquired knowledge can help compare not only the impact of gravity on various objects but also create their virtual trajectory. Simulation by Monte Carlo Method The Monte Carlo method is based on simulating the process by mathematically calculating its progress, that is, the probability of a specific event is estimated with rather a high accuracy. This method is used not only in the field of mathematics but also in economics. This work may contain evidence of the effectiveness of using this method for the further construction of a mathematical model, determine the areas of its use, and the existence of a correlation between the efficiency and scale of the complexity of a particular research issue. The Significance of Wind Engines Taking into account that wind energy belongs to renewable resources, wind engines are becoming increasingly important due to the constant decrease of global reserves of natural resources. Wind power generation is exceptionally ecological since it reduces the environmental burden, but there are still some issues that need to be clarified. Firstly, it is necessary to find out which kind of wind engines is more effective, namely, linear or vertical type, and compare it with the efficiency of other types of alternative methods of energy production. Transformers and Their Applications Transformers are devices for increasing or decreasing the voltage. Although they are mainly used at power stations, their application is much more extensive than in open and closed space. This laboratory work can investigate the essential elements of the structure of the transformer, the principle of its operation, and the ability to transmit energy over long distances with less cost comparing its power with other transmission devices. Effect of Mineral Fertilizers on the Chemical Composition of Vegetables Today, there is not only the possibility of growing different crops but also applying many fertilizers during this process. Despite the existence of various types of chemical and natural substances, mineral fertilizers are in particular demand in the sphere of agriculture. Items that should be included in the paper are types of mineral fertilizers, that is, complex or simple, and their influence on the chemical composition of various vegetables. Drinking Water Quality Report The water quality depends on a particular chemical and biological composition. Its qualitative features can be estimated only by objective indicators. The report should be devoted to the analysis of drinking water in a specific area on the basis of compliance with established biological, physical, and environmental standards. Modern Methods of Studying Blood Characteristics A general blood test involves a quantitative and qualitative study of blood elements. Although there are three main groups of blood test methods today, their effectiveness varies considerably. The lab report can be based on the comparison of colorimetric, gasometrical, and titrimetric methods, and determination, which of them is more effective for diagnosing some diseases. Influence of Noise on the Nervous System The human nervous system is especially susceptible to all surrounding factors. The acoustic stimulus not only affects the organs but also contributes to their transformation. The key purpose of this work is to determine which noise level, which frequency, duration of action can adversely affect the nervous system. Besides, this study must necessarily take into account the individual characteristics of the organism. Influence of Abiotic Factors of Environment on the State of the Immune System The condition of environmental factors has a significant impact on human health. Given the number of living organisms and parasites that exist alongside humans, the immune system is the most vulnerable to abiotic factors. This report focuses on the main environmental factors not is caused by human activity and their impact on the immune system of the individual depending on the place of residence. Determination of the Quality of Detergents The development of the production and use of detergents is steadily increasing. Despite this tendency, the effectiveness of the wide range of cleansers remains in doubt. Therefore, the principal purpose of this lab report is to establish methods of technical and economic evaluation of detergent quality. Such an assessment would be especially beneficial for analyzing their effects on the human body. Quality Control of a Certain Pharmaceutical Product Taking into consideration all the cases of violation of the pharmaceutical production process and poor quality of raw materials, the composition of the drugs should be subjected to exclusive control. Despite the existing standards that medical companies have to comply with during production, some drugs still require more scrutiny. This report can include the key standardized indicators of pharmaceutical production and comparisons with medicines that do not comply with these standards. Issues of Child Injuries in Modern Conditions Although injuries are a severe problem of the present, its impact and side effects are often underestimated. It is clear that no age group of the population is insured against such kind of injuries, but children are the most prone and vulnerable to damage. Therefore, the report should include the concept, classification of child injuries, and measures aimed at reducing this tendency. Determination of Nitrate Content in Food Even though a person consumes nitrates in the prospect of one’s life, their excessive amount can adversely affect human health. Although nitrates are a mandatory component of food and are essential for the human body, there are still certain admissible levels of its consumption. Consequently, the report should be concerned on a list of products that may contain these salts and its maximum allowable doses. Development of New Methods for Checking the Acidity of Milk and Dairy Products Acidity is one of the chief indicators of the freshness of milk and dairy products. Increased acidity can pose a particular threat to the human body, which is characterized by a remarkable sensitivity to lactose. The work should focus on indicators of the maximum acidity of milk of different varieties and methods of checking liquid for freshness. Effect of Dustiness and Air Pollution on the Function of the Human Respiratory System The human body needs fresh air constantly, but the air that people breathe in may contain a lot of harmful substances. Solid or shallow materials can cause irreparable damage to humans organism. This laboratory report can include the illnesses, which can lead to excessive inhalation of such elements, their permissible amount, and preventive measures for the treatment of respiratory diseases. Conclusion It goes without saying that the lab report is an extremely complex task due to its accuracy requirements, but on the other hand, such work is beneficial for the development of rational thinking and more profound knowledge of natural sciences. The ideas of those laboratory leads, which are presented above, prove that â€Å"hard† sciences can be not only tough for perception, but also an exciting way to learn something new. Generally speaking, it is worth to mention that science is not only complicated but also incredibly fascinating.

Abstract and Concrete Nouns Explained

Abstract and Concrete Nouns Explained Abstract and Concrete Nouns Explained Nouns are naming words and an essential part of the English language. They fall into two main categories: concrete and abstract. It is vital to learn how to use both types in your written work, particularly abstract nouns, which can be tricky. This blog post will take a quick and simple look at the basic definitions of these nouns and offer examples to clarify how they should be used. Concrete Nouns Concrete nouns are fairly simple to understand, as they basically refer to things that are solid, like concrete, and that physically exist around us. This means that we can experience concrete nouns through our five senses, in that we can touch, see, smell, taste, and/or hear them. Examples of concrete nouns include: People (man, woman, dentist, proofreader) Animals (dog, cat, bird, bee) Objects (clock, book, computer, pizza) Places and geographical features (mountain, valley, Norwich, France) Abstract Nouns In contrast to concrete nouns, abstract nouns name things that do not exist physically, such as thoughts, ideas or concepts. They are therefore used to denote things that we cant see, smell, taste, and/or hear. Examples of abstract nouns include: Qualities and characteristics (beauty, kindness, wit) Emotions and states of mind (love, happiness, anger) Concepts and ideas (justice, freedom, truth) Events and processes (progress, Thursday, Christmas) If youre still unsure about the difference between concrete and abstract nouns, let the experts at Proofed help you with your noun usage today!

Inclusion - Essay Example Hence, it is becoming more and more undesirable to restrict the number of educators in a school who possess the capabilities to teach disabled learners to only a small number of special education teachers. Moreover, regular education teachers should be skilled in teaching disabled students of functional literacy abilities such as reading, writing, communicating, and of achieving high educational performance (McLeskey & Waldron 2000). As inclusion acquires greater reputation in education, we will surpass the requirement of alluding to inclusive classrooms as if they were separate and very different from regular classrooms. In the future, every classroom will be obliged to be inclusive, and we will then finally be able to discard the term. First-rate education is a form of education that is excellent for everybody. Children come from various racial, ethnic, and national backgrounds and different economic contexts. And a number of children have disabilities. If the educational system is to be first-rate, it should be founded on the principle that every student has the capability to learn, and it should motivate every student to aim for the best and have high expectations. We cannot let the potential of any student to go into waste if we aim to improve and prosper. Effective inclusion demands the assimilation of an important vision, a research base, and feasible strategies. A lack of important and integrated vision of the objective for educating every child means a loss in educational direction and hence turns out to be subject to political convenience. Without research support, inclusion stays defenceless to arguments that are determined merely by sponsorship and not by distinction (Ballard 1999). Without sensible strategies for execution, inclusion stays to be an ideal that will refuse to be applied in the real world. The inclusion of disabled or special education students in the regular classroom is an

Determination of Protein using Biuret Reagent Lab Report

Determination of Protein using Biuret Reagent - Lab Report Example The methods used are all optical methods. This means that the level of protein concentration depends on optical characteristics (turbidity or absorption). These optical properties are measured using a tool called colorimeter or spectrophotometer. Other useful methods are volumetric, gravimetric, among others (Slater, 1986, 12). After the reaction between the reagents and the protein substrate, the peptide bond turns purple or violet for positive results. We cannot conclude that there is the presence of protein by candid colorimetric methods. This is because proteins are colorless. However, absolute estimations can be made to analyze the protein in the solution (Slater, 1986, 12). A stable color is achieved. It is always advisable to take all reading within the first 10mins for the purpose of clarity. In many experiments, biuret can be scaled using smaller sized cuvette, which consumes less protein. Proteins with abnormal low or high percentage of amino acids and aromatic side groups always gives low or high readings, respectively (Robinson, and Hogden, 1940, 32) In the case of bovine serum, albumin will obviously develop a linear relationship between the amount of protein and absorbance over a range of 0.5 to 20mg protein. However, analysis show assay below 0.5 mg is not reliable. In other cases, the upper limit may increase depending with the reagents. A straight line graph is achieved after plotting the relationship between protein concentration and absorbance. This means that there is a tremendous increase in absorbance with an increase in protein concentration (Layne, 1957, 23). The reagent is made up of potassium hydroxide. It also has traces of hydrated copper (II) sulphate and potassium sodium titrate. The blue color appears as a result of presence of proteins, pink and blue may also arise in the presence of short chained polypeptides. A biuret reagent is not required in all protein tests. It is
