Patient Isolated And Public Health Investigations Assignment
Patient Isolated And Public Health Investigations - Assignment Example  The CDC confirms Europe based tourist who raised earlier suspicion of Ebola attack positive  The tourist, who visited West Africa earlier, was isolated soon after he indicated symptoms of the contagious disease. Apparently, the patient is under isolation and close check up. On Sunday, October 19, the tourist reported a low-grade fever throughout the night and immediately received a referral for testing at the States’ most reputable laboratory. As a precautionary measure after observing the unusual fever, CDC staff isolated the tourist and interviewed him to establish additional contacts or potential exposures. Currently, one close contact has been identified, and appropriate measures employed to prevent further spread of the disease. Careful monitoring and scrutiny of all tourists and associated health care workers who interacted with the isolated patient, therefore, is directed to offer the public an assurance of the absence of a trace of the disease in America.  Ebola is an infectious, deadly disease noticeable by fever and severe internal bleeding, spread through physical contact with the infected person’s body fluids.  The outbreak of Ebola experienced in West Africa in 2014 is the largest, so far in history according to records by the CDC, 2014. The disease has an average of 8 to ten incubation period. The CDC, therefore, recommends immediate isolation and close monitoring of suspected individuals with symptoms for a period of 21 days.

Arthur Miller Essay Example for Free
Arthur Miller Essay The theme of morals and guilt is explored by the characterization of John Proctor. Proctor is portrayed as being around the age of thirty and a well-respected farmer in the towns community. He is described as the kind of man- powerful of body, even-tempered, and not easily led. From these descriptions, we recognize that he is a strong, calm individual who is quite cynical. As soon as Proctor appears in the play we see that he is very much in conflict with himself due to the terrible secret he conceals within the dark and forbidding chambers of his heart. A history of sin, which goes against every moral fibre of his body and the society in which he dwells. He is a sinner, a sinner not only against the moral fashion but against his own vision of decent conduct. John Proctor is guilty of committing adultery with the young Abigail Williams while she was serving as a servant in his household and this has a great effect on his conscience. Proctors conscience eats away at him throughout the play as it manifests itself into his relationship with people, especially his wife, Elizabeth. This is presented when Elizabeth states: I do not judge you. The magistrate sits in your heart that judges you. I never thought you but a good man, John- only somewhat bewildered. Here we see the idea of morality being reflected on a personal level, or Proctors conception of himself. He conceives himself as a blatant sinner because of his raw deeds, being his lechery. I blush for my sin, he admits to his wife. Overall, through the characterization of John Proctor the theme morals and guilt is presented and from this we see that his perception of right and wrong are decided by his own vision of decent conduct. Characterization is essential to the exploration and development of themes in The Crucible by Arthur Miller. The characterization of Rebecca Nurse explores the theme of evil. Abigail Williams explores the themes of evil as well as the power of fear and John Proctor explores the theme of morals and guilt. All these characters and many more help develop the themes within The Crucible.

Plant hormones Essay -- essays research papers
Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized in one part of the plant and translocated to another part, where in low concentrations elicits a physiological response. There are five generally recognized classes of plant hormones; some of the classes are represented by only one compound, others by several different compounds. They are all organic compounds, they may resemble molecules which turn up elsewhere in plant structure or function, but they are not directly involved as nutrients or metabolites.

One thing plant hormones specifically control is gene expression. The exact mechanisms by which hormones regulate gene expression are poorly understood. Gene expression is part of a large amplification process. This process involves repeated transcription of DNA resulting in many copies of mRNA (1st amplification step); mRNA is processed and enters the cytoplasm where it is translated many times by ribosomes into a gene product such as an enzyme (2nd amplification step); enzymes are modified to become functional and capable of high catalytic activity even at low concentrations. They catalyze the production of many copies of an important cellular product (3rd amplification step). It is likely that gene regulation is affected by certain enzymes after initial hormone binding. Genes may be altered by secondary and tertiary messengers of a cellular cascade as well. Hormones may indirectly control gene expression through these enzymes and messengers at a number of control sites such as transcription, mRNA processing, mRNA stability, translation, and post-translation Plant hormones Essay -- essays research papers Plant hormones are specialized chemical substances produced by plants.

Own story Essay
It is often difficult to tell your own story, as you do not know where to start. It takes a lot of determination for every individual to take up responsibilities as well as responsible decisions in life. There comes a time in every individual’s life when they are confronted with oppositions from all sides, from relatives, well-wishers and from people who do not want them to do well in life. It is only when an individual overcomes these oppositions, and does in life, that which (s)he always wanted to do, that the individual experiences satisfaction and pleasure in narrating her/his story. I feel happy to narrate my story, purely because I have always followed my dream. Literature is a subject that I have loved from the age of fourteen and continue to do so. This passion for my subject is what encouraged me to take up literature for my graduation and the only bit of support that I had in doing so was that which I received from my parents. Being born into a family full of conservative science graduates who were ready to accept nothing but positivism, I had to face resistance, a mighty lot of it. My high grades in English language at National level school examinations were not at all impressive to most of the people who were ‘truly concerned’ about my future. Nevertheless, the unrelenting support that I received from my parents was the main factor that gave me strength to face this resistance. Hence, I pursued my dream, leaving behind all the grumblings of discontent from my well-wishers and entered my beloved classroom in one of the most prestigious colleges of my State. It is in this classroom that I discovered that I had taken the right decision after all, and started loving my subject even more. Having a military background often helps people to cultivate various qualities like punctuality and a temper that can never stand non-sense. They are the people who get an opportunity to travel a lot in their childhood and this further helps them to communicate easily and express themselves without any ambiguity. Since my father served as a Wing Commander in the Indian Air Force, I was fortunate enough to meet many kinds of people from various backgrounds, could make friends easily and could communicate effectively. These communication skills helped me a great deal with my academics and contributed to my success as a student, as proven by the position I hold in the class rank list. Education is empowerment and every individual has a right to this empowerment. Bias and prejudices based on caste, creed and poverty should never come in the way of this empowerment. Children should never be denied the right to education, merely because their parents cannot afford to send them to nice educational institutions. Keeping this view in mind, I signed up in Make A Difference charity organization, which helps to teach under privileged children important subjects like English, Computer Science and Placements. I have enrolled as an English teaching volunteer and this organization aims at teaching the Cambridge syllabus for English, that which is taught in most of the International Schools in the country. As a volunteer, I would like to give these children the best as they have an equal right to education. The urge to become independent is usually a driving force when it comes to youngsters seeking employment. This urge, combined with a desire to be of financial help to my family is what led me to register at www. asiawriters. com. Writing is a boon given by God and at the same time, it is a talent that I have cultivated since childhood. I wanted to take maximum advantage of my talent in order to pursue my career as a freelance journalist. That is why, today, at the age of eighteen, I find myself writing this article. With the very little experience that I have in life and with acknowledging the fact that I am only a student, who recently completed her 1st year BA English Literature, I can say that this is my story. The above-mentioned reasons have made me what I am today and although I am aware of the fact that I am a very young girl, I feel happy at having realized my dream. It was always my dream to learn literature and I have always dreamt of writing. Today I feel that I have accomplished something.

Arts or Protection of Enviroment
Obviously, both of these two choices have their own reasons that our society could get benefits from each of them. In the past several decades, remarkable achievements have been made in the arts, while our natural environments are increasingly getting worse and even more difficult to handle. Under these current circumstances, I believe that it is not so hard to make decision about this question. The company should choose to protect the environment.The first and the most important thing is that we must survive on this planet that allows us almost every possibility, including supporting the arts or something like. These days, our natural environments are under the threats of contamination, global warming, extinction of species, etc. For example, the oil leaking on the Gulf of Mexico, has contaminated a large amount of sea area. And this not only has a negative effect on ocean-life, also it has influence on our life strongly. Therefore, it is very worthy to costing some money to protect the environment.Furthermore, spending some money on protecting the environment is a good investment to a company. It is from fact that our every activity is based on our environment. As far as I am concerned, if the company spends some money on environmental friendly issue, it will gain more public attention and earn more supports by which the company could grasp the best opportunity to develop more successfully. In return, the company would also do more and more things that good to the environment.Finally, giving some money to protect the environment is one thing, and doing the precedent to protect environment is quiet another. If a company take a good example for protecting environment, it is easy to imagine that this successful precedent will provoke the public and also other companies to protect our brittle environment. By means of this, I believe that more environmental protection programs which are running for our wellbeing will come into being. In view of the above concerns, the company should choose to protect the environment rather than to support the arts.
