Biochemistry involves Essay Example for Free

Biochemistry involves Essay Biochemistry involves the study of biological processes and chemical analysis which include living organism’s reactions, chemical compounds and elements. Historically, biochemistry gained prominence in the early 20th century when research on origin of living organisms began, various forms of scientific methods where used toward the success the makeup, several questions raised where; how biochemists seek to know how the brain works, the effectiveness of molecular compounds on the immune system. Furthermore, they are interested in cellular replication, differentiation and the interconnecting relationship between cells and organs. They deal with the chemical explanation of inheritance (traits, character, etc. ) and disease. Apart from this, biochemist also determines how certain molecules such as proteins, nucleic acids, lipids, vitamins and hormones function and their involvement in metabolic processes. Mostly on regulation of chemical reactions in living cells because this shows the complex chemical reactions that occur in a wide variety of life forms. It provides the basis for advancement of medicine practically such as veterinary medicine, agriculture science and biotechnology and exciting new fields such as molecular genetics, bioengineering etc. The developed knowledge and methods are applied to in all fields of medicine, agriculture, chemical and health related industries. Biochemistry also provides a unique research on protein structures and functions, genetic engineering and the two basic components of the rapidly expanding field of biotechnology. Being the vastest of all biological sciences, biochemistry has many fields namely neurochemistry, bio-organic chemistry, immunochemistry, physical biochemistry, molecular genetics, biochemical pharmacology and clinical biochemistry. Recent progress in these areas have developed a relationship between technology, chemical engineering, computer engineering. Reference: †¢ Biochemistry. (2008).

Dr. Linus Pauling - A Model of Courage Essay -- Argumentative Persuasi

The Strength of Character of Dr. Linus Pauling When it comes to moral courage, no one thinks of scientists. Moral courage brings to mind the Chinese protestor who leapt in front of a tank in Tiananmen Square, the conductors of the Underground Railroad who led slaves to freedom, and the freedom fighters of the Warsaw Ghetto, who fought to their deaths against the Nazis. The Chinese protestor, the northern conductor, and the Jewish resistance fighters were common people transformed by extraordinary times. Their moral beliefs led them into danger that was immediate, terrifying, and tangible. Some forms of moral courage are less obvious. In fact one of history's greatest examples of moral courage comes from a place no one would ever expect - the field of science. It may not seem possible to compare a man who worked in a laboratory to a man who guided slaves to freedom. After all, the Underground Railroad conductor physically risked his life day after day, but the danger that one brave chemist faced was just as real. A brilliant chemist, and a man of unshakeable moral convictions, Dr. Linus Pauling protected the human race from the unparalleled danger of nuclear war. Pauling's moral stand is a model for morality in science. During World War II the United States employed scientists on the top-secret atomic bomb program. Desperate for a weapon to use against Germany and Japan, the government recruited all the best American scientists. One of the few scientists to refuse to work on the bomb was Linus Pauling. It was a difficult decision because the Federal government was exerting a lot of pressure on him. In addition to the pressure, the project itself was hard to turn down. A scientist lives for a proj... ... will be responsible for using science morally. And that is why Linus Pauling is so important to me. In the face of great pressure and danger, he took a moral stand for his beliefs. He is my role model for his moral courage. Pauling's moral stand was not glamorous. It was not the glorious heroism of the movies. But if moral courage is supporting one's beliefs no matter what, then Pauling clearly was a hero. He was threatened by the atomic bomb no more than anyone else was but he alone decided to take responsibility for it. He knew the devastation of the bomb, and as a scientist, an American and a human, he refused to dodge his moral responsibility. Pauling is a role model and a moral hero because he bravely stood for morality on behalf of the human rare. 1 "Interview with Dr. Linus Pauling", Regents of the University of California, Berkley, 1996.

Capital stracture

Key factors that affect structure choice 5. 1. 1 Profitability and variation of profitability Profitability is one of the most tested company characteristics In empirical research regarding companies choice of capital structure. The trade-off theory predicts that higher profitability is associated with Increased debt levels and the reason for this Is twofold.First, companies achieving high profitability have less risk of financial distress and bankruptcy, so the cost of debt Is lower. Second, higher profitability means that companies can achieve higher utilization of the Interest tax shield by Increasing the amount leverage and hence the promised Interest payments each period. Similarly, Increased debt will serve as a adolescently factor for managers when free cash flow likely Increase with Increased profitability.However, as dynamic trade- off theory predicts adjustment costs will prevent companies from adjusting the capital structure immediately and the unlikelihood of companies be ing at their refinancing points at the time of measurement causes the prediction of the found allegations between leverage and profitability to be negative due to the static nature of the determinant analysis. Retained earnings are the favored financing according to the pecking order theory which contradicts the predictions made by trade-off theory.Higher profitability should enable the company to retain more earnings which is the preferable source of funding, and as such, the amount of leverage needed by the company should decrease. Empirically, profitability is consistently found to be negatively related to leverage, as predicted by both theories. Therefore the following hypothesis is made 5. 1. Asset Tangibility (Asset in place) The thought behind asset tangibility as a determinant is that tangible assets provide more security for potential investors as assets can serve as collateral.This will reduce the risk for debt holders and ultimately reduce the cost of debt for the compani es and they will be able to operate with higher leverage ratios without Incurring higher financial distress costs. Accordingly, the trade-off theory predicts that companies In which tangible assets accounts for a large part of the asset structure should Include larger debt levels than companies with a relatively larger amount of Intangible assets. Furthermore, collateralized debt makes It difficult for Investors to conduct asset substitution as the debt holders have collateral In specific assets.Therefore agency costs should be lower between shareholders and debt holders, and companies should use more debt relative to the amount of tangible assets they own. The pecking order theory makes the opposite prediction as It suggest that tangibility will generate less information asymmetries between potential Investors and shareholders, and hence the cost of issuing equity will fall, resulting in lower levels of used to predict that the cost of debt will fall as they will now be able to hav e alliterated debt.So unless the cost of equity falls below the cost of debt, the pecking order theory implies that companies will use the cheapest sources of funding, debt would still be the preferred funding to equity, at least for moderate amounts of debt. Therefore the prediction of the pecking order theory might not be as unambiguous as some researchers argue. Based on predictions of these theories and the consistent findings in previous empirical research the following relationship between asset tangibility and leverage is expected. 5. 1. Growth Opportunity Growth opportunities calls for a similar reasoning as previously used to explain the predictions of asset tangibility effect on leverage, although with opposing conclusions. The first notion of the relationship between growth opportunities and leverage is made by Myers, who states that the problem of shareholders making suboptimal investment decisions is more severe when a company has more growth opportunities as potential investors cannot value or decide which growth opportunities the company should follow.The value of a company's growth opportunities are most likely only valuable to the individual company, or at least less liable to other companies, in which case the costs of financial distress and bankruptcy will be higher for companies with many growth opportunities. With this consideration the trade-off theory suggests a negative relationship between growth opportunities and leverage.Similarly, with many investment opportunities the earnings before taxes is assumed to be lower in which case companies will not be able to fully utilize the interest tax shields associated with high amounts of leverage. Furthermore, companies having more investment opportunities likely value financial legibility highly, which also reduce the optimal leverage ratio. Contrasting this prediction is once again the pecking order theory, as it predicts a positive relationship between debt and growth opportunities.The argum entation behind is that growth opportunities involves higher information asymmetries as shareholder are not willing to reveal much information about their investment opportunities, and given that investment opportunities requires investment outlays and thus increasing a company's financing deficit, companies will issue debt financing and preferable worth-term financing when they experience finance deficits. The empirical results show consistent behavior of the relationship between leverage and growth opportunities and it is expected that this behavior is also present for Danish companies.
