History of Penicillin

History of Penicillin Free Online Research Papers Penicillin was discovered by a Scottish scientist Alexander Fleming in 1928.1 However, a man named Laureate Howard Walter Florey was the first to use it as a medicine. Fleming found that certain blue-green molds inhibited the growth of the bacteria Staphylococcus. Mold from a cantaloupe was found to have the best quality of penicillin mold. After this Fleming isolated the mold and saw that it was a Penicillin mold. Penicillin is found to be most effective against Gram-positive bacteria and not effective against Gram-negative organisms.1 Penicillin is an antibiotic used to treat bacterial infections. The types of pathogens it can treat are Staphylococci, Streptococci, S. Pneumonia, or bacterial pneumonia, Bacillus anthracis, Neisseria gonorrhoeae, and Treponema pallidium. Penicillin works against an enzyme called Transpeptidase, which aids in the formation of the cell walls in bacteria.3 Transpeptidase links amino acids into peptide chains that are part of the bacterial cell wall. When penicillin is taken it blocks the action of Transpeptidase. This causes the wall of the cell to be very weak in places. As a result, the bacteria can no longer grow.3 There are quite a number of reactions that can occur from penicillin. They include: diarrhea, nausea, rash, hives, and sometimes seizures. Also, penicillin has been known to make birth control pills less effective, often causing pregnancy. The allergy to penicillin is the most reported medical allergy. However, only twenty percent of the patients who claim to be allergic to penicillin truly have an allergy. Most people don’t understand that Penicillin was discovered, not invented. Also, when it was first used people often overused penicillin which lead to numerous penicillin resistant strains of bacteria. This can also be caused by not finishing a prescription completely. Interestingly, there are about fifteen different types of penicillins, some are: Metampicillin, Broadcillin, Epicillin, telampicillin, and Sualcillin.2 Probably the most misunderstood thing it that it does not kill bacteria, it prevents the growth of it.

IS Security Essay Example | Topics and Well Written Essays - 1250 words

IS Security - Essay Example Therefore, manufacturers have come up with security systems that protect the operating system and application from attackers, but this system do not ensure 100 percent security guarantee. However, those produced for operating system are proving more effective than those developed for application due to various factors addressed in this paper. This has made most people come to a conclusion that there is less attention to applications compared to the operating system, which is not the case. Why a good level of security is achieved in operating systems than applications The frequent patching and updating of operating system limits the chances of attackers from attacking the system. On the contrary, it appears that operating systems get more attention than applications. This section provides information on why there is a perception that operating systems have higher levels of security than applications. ... On2 the same note, other types of threats that should be considered are interceptions, modification, fabrication and interruptions, which are similar to the threats experienced in computer applications.2 Applications run on the operating systems. Therefore, it is easy for an attacker to use the application file or vulnerability to attack the operating system either through one application or by infecting other applications. This enables the user or system administrator to detect the attack before affecting the operating system, hence the misconception that security threats are more prevalent in applications than operating systems. One difference between operating system security issue and application is file permissions. An example of this is when an application misunderstands the semantics of an operating system file or totally omits a check. This problem does not occur in operating systems; this stems from the fact that any attempt to open a given file will prompt a permission chec k as the file permissions link to individual files.2 On the other hand, some operating systems mechanisms result to complex security issues for the applications used today. Operating systems are not flexible in offering support, resulting to a compromised security issue. An example of such operating system is that of UNIX, which violates some privileges by only supporting a two level privilege that includes root and user. To limit these 3limitations, it introduces â€Å"set user id†, â€Å"set group id† and â€Å"chroot (2)† that are particularly limiting and inadequate. These applications aim to become responsible for granting permissions, accepting requests, and managing resources, which

Human abortion Essay Example | Topics and Well Written Essays - 2000 words

Human abortion - Essay Example Recently there has been frequent talk in many states in opposition and in support of the abortion law. Abortion law some say is ethically incorrect as it takes away a life of a fetus which is growing inside a woman's womb in a sort abortion takes away a life while some say that abortion is right as they see the only way for eradicating any signs what a rape victim might hold to. The Roe Vs Wade case of 1973 is not for off from fortifying the fact that abortion is real and deadly issue which engulfs American cause of freedom. Roe v. Wade, (1973), was a landmark US supreme court case establishing that most laws against abortion violates the constitutional right to privacy, overturning all laws outlawing or restricting abortion. It is one of the most controversial decisions in U.S. Supreme Court history. The decision in Roe v. Wade prompted a decades-long national debate over whether terminating pregnancies should be legal (or more precisely, whether a state can deem the act illegal if it chooses to do so); the role of the Supreme Court in constitutional adjudication; and the role of religion in the political sphere. Roe v. Wade became one of the most politically significant Supreme Court decisions in history, reshaping national politics, dividing the nation into supporters and rival camps, and inspiring activism. Opposition to Roe comes prima... quality and personal freedom, and those who believe in the privacy of individual over collective rights, although the opposition to Roe often reference the privacy of the individual when referring to the unborn child. The case originated in Texas in March 1970 at the behest of Linda Coffee and Sarah Weddington, both young attorneys from central Texas. "Jane Roe and Richard Roe", a standard alias for anonymous plaintiffs, was used to protect Norma McCorvey's identity. After the initial lawsuit was filed, the case was expanded to include several other parties, including: James Hubert Hallford, a licensed physician who had been arrested for violations of the Texas abortion statutes; "John and Mary Doe," aliases for a married couple whose doctor had advised against pregnancy. At the time of the case, McCorvey claimed that she had become pregnant by rape. She has claimed and rescinded her support for the Supreme Court decision. During the case, Weddington kept private the fact that McCorvey had been raped. The law stated that having or trying to perform an abortion is a crime, except by "medical advice for the purpose of saving the life of the mother." The suit claimed that the laws were unconstitutionally vague and omitted the rights guaranteed to pregnant women by the First,Fourth,Fifth,Ninth, Fourteenth Amendments. In Dallas County, Texas the district attorney Henry Wade was the defendant in the case. A three-judge district court ruled for "Jane Roe", but refused to grant against the enforcement of the laws. Both "Jane Roe" and defendant Wade appealed to the Supreme Court and the case was argued there by Weddington and Texas assistant attorney general Jay Floyd on December 13, 1971. Burger proposed that the case be put over for reargument, and the justices, unimpressed

Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model :: Philosophy

Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model ABSTRACT: This treatise is a contribution towards the understanding of why humankind cannot agree on the foundation of morality and why moral pluralism is the logical constitution of moral reality. The synergistic-reflective-equilibrium model is the model that will describe how persons can make moral decisions as pluralistic agents. If this model is correct, then it will not be a new discovery, rather, it will be a new description of how pluralistic agents do in fact make moral decisions. This synergistic-reflective-equilibrium description should then be useful not only in giving a fuller understanding of how moral decisions ought to be made, but also how moral philosophy can be united into a pluralistic collective whole. The first part of this paper defines the synergistic-reflective-equilibrium mode. It briefly explains how it is a combination of both the theory model of moral decision-making and the intuition model of moral decision-making. The second part of this paper defines mi d-level principles and explains how they are a natural development of the synergistic-reflective-equilibrium method. It will then be shown that both Mill and Kant used this method in their own moral theories. Lastly, it will be shown how "weighing and balancing" and "specification" are integral components in this model and were also practiced by Mill and Kant in their moral systems. Introduction This treatise is a contribution towards the understanding of why humankind cannot agree on the foundation of morality and why moral pluralism is the logical constitution of moral reality. The synergistic-reflective-equilibrium model is the model that will describe how persons can make moral decisions as pluralistic agents. If this model is correct, then it will not be a new discovery, rather, it will be a new description of how pluralistic agents do in fact make moral decisions. This synergistic-reflective-equilibrium description should then be useful not only in giving a fuller understanding of how moral decisions ought to be made, but also how moral philosophy can be united into a pluralistic collective whole. I. The Synergistic-Reflective-Equilibrium Model The synergistic-reflective-equilibrium model is the position in which the justification of what is right or wrong is done by using neither a pure theory model, nor a pure intuition model. The synergistic-reflective-equilibrium model is a back-and-forth process—starting with particulars and going to the general and back to the particulars and so on and so forth. This is a constant process that never really comes to closure as new decisions are constantly having to be made.

Phases of Tragedy in Blood Diamond †the Movie Essay

Complete innocence describes the hero to be dignified, because of their innocence. Their pride and strength is overpowered by something they cannot control. In the movie Blood Diamond, Soloman walks his son to school. Showing a typical, I deal way to show complete innocence. Also showing a perfect father/son relationship before all the rebels came. With this scene showing a father and his son sharing a joke on the way to school it is shown to be innocent fun, which is a perfect example of complete innocence at the beginning of the movie. When young and innocent people first encounter realities of adulthood it is known as inexperience. A central character will live so the action closes with an adjustment to mature experience. In the movie when Danny was young he was brought up believing that the war was just about fighting against communism. As you can see in the movie, Danny has now discovered the conflict diamonds are the reason for the war. When Danny tries to smuggle diamonds, and goes to see his friend at a vineyard it shows that he has learned and has mature experience. Continuing through the stages of tragedy we see a completion of an ideal. Despite a tragic end because of the successful victory, a sense of peace is shown after the hero’s death because of a final accomplishment. Ain the final scene with Danny you see that Soloman reunited with his son. Danny knew he would die, so he made amends by calling Maddie, and giving Soloman the diamond that he worked so hard to get. Even though Danny died some peace was restored and Soloman and Maddie gave him the credit he deserved when Maddie wrote her article. Even though our hero can complete his quests, he/she has their own faults. From innocence to experience throughout stories we see our hero’s fault, but by the time they realize their faults it is too late to change. Danny knew that diamond smuggling was illegal and also wrong, but he did it anyways. In the end Danny gets shot and is in extreme pain. He only then realizes that it was all because of him contributing in the diamond smuggling. Danny did manage to regain some loyalty when he handed Soloman the diamond and told Soloman and his son to leave him there to die, so that they could escape with the diamond together. The natural law, known as fate, also takes a toll on heroes. Overshadowing the heroes/heroines and allowing the audience to look down on the action. When Soloman was at the fence there were so many people that the chance of seeing his family was slim to none. Fate clearly took part when he happened to see his family on the other side of the fence. Fate was showing Soloman that his family was still alive, so he could still try to save them. To make the audience even more sympathetic we enter a world of shock and horror. Our hero receives punishment or torture, possibly humiliation, so deep they cannot achieve a heroic pose. At the start of the movie Soloman’s village was torn to pieces. Others in the village were shot or had their hands cut off. The young boys were taken to the mines. Unnecessary torture was demonstrated to his village which was truly a world of shock and horror.

The Militarization Of American Police Departments - 884 Words

I chose to do this second paper on the militarization of American police departments. This will lend to the thesis Greg and I intend to submit for our final presentation – so we are beginning our research now. As discussed in class, the militarization of police departments is leading American police departments – city or small towns – to act like occupational forces. This is due to several different factors ranging from the availability of weaponry and tanks, to the training of the police departments, to the accessibility of locating crime by advanced surveillance and tracking systems. To further our exploration, Greg and I chose two episodes of the HBO show Vice to watch and elaborate on. For our final presentation we will incorporate these as well as a book Greg has read and some interesting research we will find online. Not only is the militarization of police departments a controversial subject, the consequences of such a transition of our police is det rimental to many. The episode of Vice, and something we are all aware of and have discussed extensively in our courses, reference that the consequences are felt far more severely on the African American population and in low income areas.
