...Black Molds and Lungs Mold infestations in buildings can be quite a dangerous and costly problem, especially when it involves the toxic black mold. Scientifically referred to as Stachybotrys chartarum, black mold is known to a number of health effects when ingested or inhaled (Ammann, 2016). The health effects and symptoms of exposure to S.chartarum cover a significant range of health issues and as such, having a clear knowledge of the indicators is necessary. The most common health effects and symptoms of S.chartarum are linked with the respiratory system. They include chronic sneezing and coughing and irritation of the mucous membrane of the throat and the nose. Prolonged exposure usually leads to more severe health effects including vomiting,...

...Mold is an unfortunate and unwelcome reality that most homeowners will eventually have to deal with. The fungus exists everywhere, even in the air you breathe. The spores of mold travel quickly, landing on any hospitable surface it can find. Sometimes these hospitable surfaces are in our homes, where they land and grow and eventually form infestations. It's important to take mold seriously and the best treatment for mold is prevention. In the Home Mold's best friend is a pesky thing called humidity. When there's plentiful moisture in the home, mold thrives. To keep mold from growing in abundance, make sure the humidity level of the house never exceeds 60%. If you're not sure the humidity level of your home, you can install a hygrometer....

...Running head: SCIENTIFIC DISCOVERY PAPER Scientific Discovery Paper On Penicillin Tracey Ann Elledge University of Phoenix, Las Vegas NV Creative Minds and Critical Thinking PHL 458 Cornell Horn, M.A.; M.A. December 01, 2009 Scientific Discovery Paper Penicillin is an antibiotic that destroys bacteria by destroying the cell wall of the microorganism. It does this by inactivating an enzyme necessary for the cross linking of bacterial cell walls. The enzyme is known as the Tran peptidase. It accepts the penicillin as a substrate, it the alkanolates a nucleophilic oxygen of the enzyme, rendering it inactive. Cell wall construction stops and the bacteria soon die. The antibiotic nature of the penicillin so due to the strain lactam ring, on opening the ring strain is relieved this makes penicillin more reactive than ordinary amides. Before penicillin a simple pinprick or tiny cut could have been lethal. There are so many people easily catching infections that would rage out of control. Children died regularly from scarlet fever, from infections of the bones, throat, stomach or, brain. Many of us would not be here today had it not been for the discovery of penicillin. In 1928, Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade...

...works for a health care facility who has the main goal of finding ways to stop or avoid communicable epidemics in the United States. Epidemiologists study the frequency and distribution of diseases within human populations and environments. Specifically, they measure the incidence of disease occurrence and relate it to different characteristics of populations and environments. Epidemiologists perform research, education, and public health practice in universities, government agencies, international organizations, and private corporations. Therefore epidemiologists study a wide range of healthcare issues. Epidemiologist study and research regions or different populations regarding serious life threatening diseases, diseases that are infectious, the life span of illness in families a well as environmental pollutants that occur. Epidemiologists collect and further analyze important information about public health and the behavior of diseases. After researching and analyzing collections an Epidemiologist explain and also reveals to the public about the findings of their research. Epidemiologist study the distribution of health-related events in a specific population and the purpose of this study in order to control health problems that occur. “Epidemiology includes the methods for measuring the health of groups and for determining the attributes and exposures that influence health; the study of the occurrence of disease in its natural habitat rather than the controlled environment...

...diffraction to study DNA. Crick and Watson used their findings on their own research and in April 1953 they published the news of their discovery, a molecular structure of the DNA based on all of its features. Their model served to explain how DNA replicates and how hereditary information is coded on it. This set the stages for rapid advances in molecular biology which continues until this day. In the other partnership with Rosland and Franklin, Franklin produced an X-ray photo that allowed Crick and Watson to work out the 3D structure of DNA. The structure of the DNA was found to be a double helix. Watson, Crick and Wilkins shared a Nobel peace prize in medicine in 1962. Franklin had died in 1958 and despite her hard work the prize could not be received posthumously. Another way in which science and technology advanced medicine since 1750 was the development of penicillin. In 1928, Alexander Fleming whilst studying influenza noticed that mold had developed accidently and completely by chance on a set of culture petri dishes used to grow staphylococci germ. The mold on the petri dishes created a bacteria free circle around itself. He then experimented further and made the mold into some sort of medicine and named the substance penicillin. Fleming wrote down his discovery and published it. However, Fleming did not realize the potential of this remarkable discovery of a drug. Therefore, no further research was carried out due to lack of funding and specialist help. Howard Florey...

...* Management optimization of bank’s queuing system * Abstract Nowadays the queue phenomenon in the bank offices is a common and troublesome issue that nearly occurs everyday in the banks of China. The rapid tempo of life makes people pay much attention to the time management, they don’t willing to spend much time on queuing and gradually lose confidence in banks. In order to improve the efficiency and the satisfy degree of customers and finally increase the profit of banks, the banks have to do something about their current queuing system. This proposal aims at analyzing the current queuing system of the China banks, finding out existing problems and carrying out some effective measures based on the previous researches, the principle of queuing and statistic method. Under the premise of less increasing the operation cost of the banks to improve the service efficiency in order to realize the win-win result of customers satisfaction and banks profit. Background Every person no matter he is young or old may have some painful experiences waiting in the banks of China. Customers still have to wait for a period of time even when they avoid the busy hours of the banks. Not alone the busy operation time or the peak period of the banks people have to wait for ages. I also had the similar experiences when I was an undergraduate student. As a student we need to pay our tuition fee through a certain bank such as Bank of China before a semester begins. However so many students...

...however, sugarcharcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction withsulfuric acid to minimise the introduction of new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal. Subtitle: A Boise State University study proves that low-energy feedstocks can be densified and when combusted produce heat output comparable to higher energy content fuels. By Owen McDougal, Seth Eidemiller, Nick Weires. November 23, 2010 By the way, according to one of those online dictionaries, “feedstock” refers to “the raw material that is required for an industrial process.“ Intro Research at Boise State University in Idaho, explored both the caloric content and shape to optimize burn efficiency of the biobriquettes. The energy content of briquettes ranged from 4.48 to 5.95 kilojoule per gram (kJ/g) depending on composition, whereas the energy content of sawdust, charcoal and wood pellets ranged from 7.24 to 8.25 kJ/g. Biobriquettes molded into a hollow-core cylindrical form exhibited energy output comparable to that of traditional fuels. The study demonstrates that low-energy content feedstocks can be composted, pressed and combusted to produce heat output commensurate with higher energy content fuels. A calorific donut stands up to charcoal. This is an interesting statement considering the highest calorific value they...
