What is sickle cell anemia.

What is sickle cell anemia. A mother of in central Africa has had no health problems her entire life. She has four beautiful children in her lifetime. Her first child of eight years old catches malaria; he sweats in his sleep every night, experiences the chills, is plagued with the fever, and has periodic attacks. To make matters even worse he has developed the condition known as splenomegaly which causes an enlargement of the spine that cripples him to his end when he dies of anemia. The second child, a daughter, is born with the genetic condition known as sickle cell anemia. Throughout this child's life she experiences ulcers up and down her legs, many fevers, and attacks that seem to be the unbearable pain a human can withstand without passing out. She will never be around long enough for her seventeenth birthday. Her last two children live long and healthy lives. Over time Mother Nature has found a side door around malaria, but she has unleashed death with his sickle, causing people's red blood cells not to function properly in carrying oxygen, causing terrible side effects and death.English: Description Malaria versus sickle-cell tr...For a long time little was known of blood diseases. People in central Africa were experiencing pain and dieing from an unknown killer. In 1956, Dr. Vernon Ingram and Dr. Paulings tested the blood of patients in central Africa. Surprisingly there were key differences between the hemoglobin of the some patients (Silverstein 17). "Hemoglobin is made up of chains of amino acids, like proteins; these chains are folded and looped in a complicated structure"(Johnson 325). In order to break up the bonds of hemoglobin and change it into mixture of shorter amino acids, Dr. Ingram used enzymes and other chemicals. By organizing these fragments of sections, it is possible to work out a map to the...

High School Sophomore Math Curriculum and Course Study

High School Sophomore Math Curriculum and Course Study The standards for mathematics education per grade vary by state, region, and country. Still, it is generally assumed that by the completion of the 10th grade, students should be able to grasp certain core concepts of math, which can be achieved by passing classes that include a complete curriculum of these skills. High School Sophomore Level Math Courses Some students may be on the fast track through their high school math education, already starting to take on the advanced challenges of Algebra II. The bare minimum requirements for graduating 10th grade includes an understanding of consumer maths, number systems, measurements and ratios, geometric shapes and calculations, rational numbers and polynomials, and how to solve for the variables of Algebra II. All students are expected to understand these concepts at this level. In most schools in the United States, students may choose between several learning tracks to complete the prerequisite four math credits needed to graduate High School. Math classes build upon each other, so each subject must be completed in the order they are presented: Pre-Algebra (for remedial students), Algebra I, Algebra II, Geometry, Pre-Calculus, and Calculus. Students must reach at least Algebra I before completing 10th grade. Different Learning Tracks for High School Mathematics Every high school in America does not operate in the same way, but most offer the same list of mathematics courses that sophomores in high school can take in order to graduate. Depending on the individual students proficiency in the subject, he or she can take the expedited, normal, or remedial courses for learning mathematics. In the advanced track, students are expected to take Algebra I in the eighth grade, allowing them to start Geometry in ninth grade, and take Algebra II in the 10th. Meanwhile, students in the normal track start Algebra I in ninth grade, and typically take either Geometry or Algebra II in 10th grade, depending on the school districts standards for math education. For students who struggle with math comprehension, most schools also offer a remedial track that still covers all of the basic concepts students must comprehend to graduate high school. However, instead of starting high school with Algebra I, these students take Pre-Algebra in ninth grade, Algebra I in 10th, Geometry in 11th, and Algebra II senior year. Core Concepts Every 10th-grade Graduate Should Grasp No matter which education track they are on- or whether or not they were enrolled in Geometry, Algebra I, or Algebra II- students graduating the 10th grade are expected to master certain mathematics skills and core concepts before heading into their sophomore years. Proficiency must be displayed with budgeting and tax calculations, complex number systems and problem-solving, theorems and measurements, shapes and graphing on coordinate planes, calculating variables and quadratic functions, and analyzing data sets and algorithms. Students should use appropriate mathematical language and symbols in all problem-solving situations, and be able to investigate problems by utilizing complex number systems and illustrating interrelationships of sets of numbers. Additionally, students should be able to recall and use primary trigonometric ratios and mathematical theorems like the Pythagorean to solve for measurements of line segments, rays, lines, bisectors, medians, and angles. In terms of geometry and trigonometry, students should also problem-solve, identify, and understand common properties of triangles, special quadrilaterals, and n-gons, including the sine, cosine, and tangent ratios. Additionally, they should be able to apply  Analytic Geometry to solve problems involving the intersection of two straight lines, and verify geometric properties of triangles and quadrilaterals. For Algebra, students should be able to add, subtract, multiply and divide rational numbers and polynomials,  Ã¢â‚¬â€¹solve quadratic equations and problems involving quadratic functions. Furthermore, sophomores must be able to understand, represent, and analyze relationships using tables, verbal rules, equations, and graphs. Finally, 10th graders must be able to solve problems that involve variable quantities with expressions, equations, inequalities, and matrices.

UNDER THE LION'S PAW by hamlin garland Essay Example | Topics and Well Written Essays - 750 words

UNDER THE LION'S PAW by hamlin garland - Essay Example With almost cinematographic precision the opening paragraph takes the reader in the reality of the farmer’s every day life: IT was the last of autumn and first day of winter coming together. All day long the ploughmen on their prairie farms had moved to and fro in their wide level fields through the falling snow, which melted as it fell, wetting them to the skin all day, notwithstanding the frequent squalls of snow, the dripping, desolate clouds, and the muck of the furrows, black and tenacious as tar (Garland 1). What captures the attention is the literary uniqueness of the characters. Although they are created in order to convey the author’s ideas about the organization of society, the characters in â€Å"Under the Lion’s Paw† also possess captivating dimensionality, which is revealed through their actions, feelings and struggles: The little woman's eyes filled with tears which fell down upon the sleeping baby in her arms. The world was not so desolate a nd cold and hopeless, after all (Garland 3). Garland also conveys broader notions of the organization of society and the distribution of resources through his characters. He expresses his moral views of good and evil. The social contrast between these characters is what constitutes Garland’s universe and the human values on which it is based. One of the leading characters in the story is Timothy Haskins. He is the embodiment of the average, hard-working man, who is ready to sacrifice everything in the name of his ideal, which is his family. Haskins is Garland’s vision of the hard-working, honest man, who has internalized the constraints of the system, which in most of the cases works against him: Many a night he worked till his anxious wife came out at ten o'clock to call him in to rest and lunch [†¦] No slave in the Roman galleys could have toiled so frightfully and lived, for this man thought himself a free man, and that he was working for his wife and babes (Ga rland 10). Timothy Haskins represents the individual aspect of a social struggle, against land speculation and unfair taxation in the 1880s and 1890s. In this sense the story sends the author’s message for social reform as the only road to democratization. The antidote of this vision of social and economic equality is Jim Butler. He is the collective image of those, who have gained economic supremacy through illegal means, and greed has transformed their capacity to create into capacity to dominate. It is difficult to say whether Butler is morally corrupt or just taking advantage of the system. Jim Butler was one of those men called in the West "land poor† [†¦]But a change came over him at the end of the second year, when he sold a lot of land for four times what he paid for it. From that time forward he believed in land speculation as the surest way of getting rich (Garland 5) Finally, Steve Council represents the virtues of society, such as compassion, trustworth iness, sincerity, empathy, honesty, and kindness. These are the pillars of society, as envisioned by the author, which he has embedded in Council’s uncomplicated, noble character. Council moved about uneasily in his seat and stopped his stammering gratitude by saying: "Hold on, now; don't make such a fuss over a little thing. When I see a man down, an' things all on top of 'm, I jest like t' kick 'em

Information systems of business Essay Example for Free

Information systems of business Essay A business have to manage lots of different information. All information systems have 2 big issues, one is the organisation who receive the information and the other is that appropriate members of staff gets the information. A number of policies have to be put in place concerning security of information, backups, health and safety, organisational policies, costs and increasing sophistication. Security of information can be an operational issue. It is all about maintaining the integrity and availability of organisational information and knowledge. Managers need to have the right information available at the right time to make good decisions. The reliance on technology to store information increases which means the risk posed by system failure and malicious attack from viruses also increases. IT security policy should take into account common risks to information the business relies upon. This policy should include secure login id for IT systems and controls that limit access to information. Backups are also an operational issue these are stores on separate hardware from the live versions of the information. Health and safety can be an operational issue. There are many regulations concerning health and safety. The Health Safety (Display Screen Equipment) Regulations 1992 this is the minimum requirements for work stations and includes the extent to which employers must ensure that workstations meet the requirements laid down in this schedules, the equipment, the environment and the interface between the computer and operator. Another is the management of health and safety at work regulations 1992 this is that every imployer shall provide his employees with comprehensible and relevant information.

Tort, Negligence and Nuisance Claims :: Tort Law

A number of aspects of liability rise from this case study and each one will be discussed. With regards to the headaches suffered by Karl, it is necessary to look at private nuisance. Negligence is disregarded as it is assumed from the details in the case study that the headaches suffered are not so serious as to cause personal injury, it is just described as ‘mere discomfort’. Such a claim under the law of nuisance requires three factors to be fulfilled. The first being a continuous interference. This is shown in De Keyser’s Royal Hotel v Spicer Bros Ltd (1914) 30 TLR 257. From the case study one can assume that it is a continuing interfering act and not a one off. Secondly, the interference must be unlawful or unreasonable. This is up to the claimant to prove. The rule for this is sic utere tuo ut alienum non laedas (So use your own property as not to injure your neighbour's). The locality in this instance reflects the unreasonableness of Jane’s actions. It occurred in a residential area and therefore such Gases were not to be expected. The duration of the act will also be taken into account. Because Jane is a young inventor it is assumed her work is an ongoing process and not a one off as explained above. The seriousness is also considered. In Walter v Selfe (1851), Knight-Bruce V C said â€Å"an inconvenience materially interfering with the ordinary comfort physically of human existence, not merely according to elegant or dainty modes and habits of living, but according too the plain sober and simple notions among the English people.† This shows Jane’s actions would be deemed unreasonable, heightened by the fact that the incident occurred in a housing area, not an industrial estate. The sensitivity of the defendant, the utility of his conduct and a malicious aspect may be also discussed but this is not relevant in this case. Thus the second aspect of unlawful or unreasonable interference is established.

Home Depot and Lowes Financial Analysis Essay

ANALYSIS: For the past two years (2012-2013) both Home Depot (HD) and Lowes (LOW) appear to be performing companies. However, overall Home Depot is a significantly stronger company. The total sales growth for HD is 3.0% versus 0.3% for LOW. A comparison of the Short-term Liquidity reveals that HD and LOW both have compatible current ratios. However, the Quick Ratio provides evidence that HD has a much stronger operational efficiency. The Days Receivable, Inventory and Payables all validate the efficiency of how HD is managing their inventory and accounts. Based on this simple fact alone, HD is performing well above LOW. The difference of profitability is highlighted at the significant difference in sales growth of HD (3.0%) versus LOW (0.3%). Within all categories of profitability, HD is out performing LOW. The return on assets to generating profits is proving to be very effective for HD. HD has separated itself from LOW in its capability and efficiency. HDs total asset and investmen t returns clearly separate them from LOW. The HD return on investments categories is almost double for HD over LOW. It is this efficiency that gauges hoe much more effective HD is at putting investments to work to generate revenue. The long-term solvency ratios show that HD is also a much more secure company. The interest coverage is comparable to both companies. However, the Long-Term debt to common equity shows the leverage that HD has over LOW. It only has a very conservative 2% reliance on their debt versus a very high 52.9% for LOW. This difference shows the risk factor that could potentially affect the ability of LOW to repay their debts. The market ratio shows similar price earnings for both HD & LOW. The beta is also compatible and highlights the risk that LOW is slightly higher than HD. The HD Common Stock Market to Book Return, illustrates how HD has almost doubled their market value of their stock to the amount invested by stockholders. This is an incredible strength for any company to achieve. LOW also has a solid ratio, just not as strong as what HD has. The cash flow from operation/net income shows a slight higher ratio for LOW. There was definitely a spike for all cash flow for LOW from 2012 to 2013. HD fell slightly behind LOW at the operational/new income ratio. However, HD is considerably stronger in the cash from operations/investment proving their ability of using internally generated cash from operations to expand the company if desired. The overall winner between HD an LOW is no  question: Home Depot! The company is simply performing much better than Lowes in virtually every financial category as a company. Regarding the DuPont Analysis. In the 1920’s the DuPont Corporation developed what became known as the DuPont analysis, a technique which uses basic accounting identities to break down the return on equity into either 3 or 5 component parts. Based on the information within the report, HD has consistently achieved greater success and proves to be secure enough that it will continue this future trend. The overall N et Income/Sales & Earnings to Price Ratio illustrates clearly that operationally HD is a much better company than Lowes.
