Anal cancer is highest among men having sex with men at 35 in every 100,000 of them in this locality (Health Communities 2010). The rate is lower among 100,000 heterosexual men. Anal cancers are located in the peri-anal skin around the anus in men, equivalent to tumors in the anal canal in women. These are typically squamous cell carcinomas, which may spread to deeper layers of tissue. Their exact cause is unknown but associated with HPV. Aside from smoking and alcohol consumption, HPV and ano-genital warts are associated with anal cancer both from past and current infections. Most men who get infected are more than 50 years old and may…… [Read More]
Pathogenic & Nonpathogenic
Microorganisms have the capacity of causing severe disease if the conditions are ideal enough to sustain the life of these microbes. As more and more microbes are able to grow, the risk of disease development rises. Although all microorganisms have the capability of producing virulent effects, some are more able to do so than others. Pathogenic microorganisms are strong enough to fight off the natural defenses of the human body and are therefore almost guaranteed to cause some sort of disease (Murray & osenthal, 2008). On the other hand, non-pathogenic microorganisms or opportunistic microorganisms are only able to cause disease if the body's natural defense system is compromised through either an illness such as HIV, or through the taking of medications that may temporarily suppress the immune system (Murray & osenthal, 2008). All types of microorganisms need to be in their ideal growth environment, or ecological niche,…… [Read More]
Microorganisms Through a Microscope
The Gram stain test distinguishes two fundamental cell varieties of bacteria. The latter also determines the presence of bacteria. "Gram-positive" refers to the type that retains the original crystal violet stain. In contrast, the decolorized stain red depicts the "gram-negative" variety. The significance of the staining plays a crucial role in the determination of the appropriate treatment for an infection. Often, the clarity in distinguishing between viral, fungal, and bacterial infections may not be attained (ojewoda et al. 2073). This requires the application of the gram stain test. Additionally, various bacterial varieties may necessitate the use of different treatments. The use of gram stain technique enables physicians to establish that the infection is because of bacteria. The test also provides fast results that are beneficial for the diagnosis process.
The acid-fast stain can be used to identify microbes in the genera Mycobacterium and Nocardia. A majority…… [Read More]
It is therefore quite important to evaluate each experience on its own merits, as well as to how well each experience is integrated into the overall picture. An evaluation form has been developed for each participant as well as the parents of that participant. The evaluation form will be handed out at the end of each of the camps (whether the attendee stayed for a one-week or the full three-week course will be noted) for completion and return to the directors of the camp.
After the evaluation forms have been returned, the responses contained therein will be analyzed and broken down into categories pertaining to each camp experience and how it (they) were perceived by the campers. Follow-up questionnaires can be sent to each participant on a bi-yearly basis in order to gauge what type of long-term effects the camps continue to have on the participants.
The project is proposed…… [Read More]
The chemical was found to turn on quorum sensing in V. fischeri, whereas it inhibited pathogen Pseudomonas aeruginosa. Also, the slow-release was shown to be far more effective than by applying the chemical directly as an aqueous solution. Since quorum sensing is also important for pathogen establishment this application could be important for inhibiting pathogenic bacteria from colonization of internal medical devices.
In summary, the V. fischeri and squid symbiotic relationship is an important model host-bacteria system. Aspects of colonization of host-symbiont and host-pathogen have been shown, using the V. fisheri and squid model, to be the same. Therefore, understanding the mechanism and complex transcriptional regulatory systems of V. fischeri could lead to potential new therapies and pharmaceutical applications. Likewise, understanding the environmental factors necessary for successful host-bacteria interactions could lead to novel drug targets. In addition to being important in understanding other harmful host-bacteria relationships the V. fischeri and…… [Read More]
Some of the symptoms of ventilator assisted pneumonia may be the onset of fever, a higher white blood cell count, and a new or changing lung infiltrate that may be visible on a normal chest x-ray. Cultures taken as samples from the patient's airways may show the presence of microorganisms or bacteria and fungi that would eventually cause the dreaded ventilator assisted pneumonia in the patient. JAMA states that these risk factors may be eliminated to a large extent if the nurses and medical practitioners were to follow certain simple but essential steps in preventing the onset of the symptoms of pneumonia. First and foremost, the nurse must maintain a high degree of hygiene; he must wash his hands both before and after coming into contact with any patient, and second, he must try to keep the bed elevated to a 30 degree head up position, so that…… [Read More]

Explaining Dental Biofilm to a Client
While showing Pamela the pink/purple disclosing stain on her teeth, she comments "oh-that is from my lunch earlier today. I did not have time to brush before the appointment." espond to her comment by explaining what the disclosing solution showed.
Lark, while I understand your concerns about the results of your recent dental biofilm examination, I would like to take some time to explain the diagnosis in more detail to help alleviate those concerns. First, it is important to remember that dental biofilm is not a disease, nor does it result from poor dental habits on your part, as these naturally occurring collections of bacterial communities are simply microorganisms functioning as nature intended. You have probably heard of plaque, while that oral health issue is widely known, and the data obtained from empirical studies during the last…… [Read More]
Genetically Modified Crop Plants
The term genetically modified organisms, popularly referred to as GMOs, constitute crops, animals and even microorganisms that have undergone development my man and technology. Through the great leaps man has developed in technology, it is now possible to 'create' organisms and plants through the combination of genes considered superior, resistant and quick-maturing. Farming and animal rearing land brings a challenge in the current world, due to population explosions. This trend has been brought about by the necessity to feed the ever-increasing food demand by world populations.
The world today carries over six billion people, a number that increases every day. The natural means of plant reproduction cannot support to feed this population due to the long time taken to grow to maturity, poor yields and the limited space for planting. Therefore, genetic modification has gained an edge in the development of such crops as…… [Read More]
The Gram-negative, motile, rod-shaped bacterium Pseudomonas aeruginosa is an opportunistic killer that takes advantage of people suffering from medical problems (Van Delden and Iglewski, 1998).For this reason, P. aeruginosa is one of the most common nosocomial infection that occurs in hospitals. P. aeruginosa is responsible for causing 16% of pneumonia cases, 12% of urinary tract infections, 10% of bloodstream infections, and 8% of surgical infections due to hospital care. Patients who are immune-compromised are also susceptible to P. aeruginosa infections, such as patients undergoing chemotherapy, suffering from HIV / AIDS, recovering in burn units, and suffering from cystic fibrosis. With death rates ranging from 30 to 60% for these patients, P. aeruginosa is considered to be a significant threat to patient health.
P. aeruginosa can switch between a free-swimming planktonic form and colonies enclosed within slime-protected biofilms attached to surfaces (Baltch and Smith, 1994,…… [Read More]
lab! she said smiling. "No wonder your grades are so awesome!"
Ann said hardly a word to me all year. Although she was in at least two of my classes each semester since I started at UTSA, I think that maybe Ann felt a little intimidated by me. Ann is an all-American college student, a woman from a small town Kentucky who had never left the greater forty-eight. The farthest place she had been to away from her home town was Los Angeles. On the other hand, I hailed from far-off Japan, a country she had probably only read about and seen pictures of on television or books. Because Ann was a science student and not a geography buff, I wondered in fact if she even knew where my home country was on a world map.
A love to research!" I told her enthusiastically, conscious that I wanted to make…… [Read More]
Pathogens and Diseases:
Pathogens are common characteristics of everyday environment as soil contains huge number of bacteria per cubic centimeter while air contains fungal spores. The existence of pathogens in everyday environment emanates from the fact that microorganisms are deposited through touching of various surfaces like tables. Pathogens can be described as disease-causing agents such as infectious microbes, and parasites. While the infectious microbes include viruses and bacteria, parasites include protozoa and fungi. Notably, microbes are only considered as pathogens if they cause harm or diseases since not all microbes are harmful (Koo, 2009). There are opportunistic pathogens, which are organisms that are normally part of the natural flora of the body. These organisms become harmful or pathogens after an invasion like the occurrence of an accidental injury or surgery.
Spread of Pathogens:
Since pathogens are common disease-causing agents, they spread in various ways to cause harm or illnesses. Some…… [Read More]
Safety and Health Issues in Meat Processing Industry
In the meat processing industry, health and safety issues are of vital importance, in view of the several risks arising out of microbial contamination of meat and the occupational hazards faced by workers. Past experiences have shown that microbial reproduction in meat and meat products can reach alarming proportions traversing across countries and even continents. The infamous mad cow disease and the foot and mouth disease in cattle has rattled the British meat industry for a considerable period, resulting in loss of image, confidence and erosion of profits. North America's main problem is the widespread prevalence of eschericia coli in meat, more commonly known as the hamburger disease. It is well-known that meat is highly susceptible to attack of bacteria and virus and hence there is a constant need to address this risk. When microbial activity sets in, the quality of meat…… [Read More]
Waste Water Treatment
Inadequately treated waste water poses hazards such as water-borne diseases and water-body pollution. People generate wastewater (sewage) in numerous ways, including laundry and toilet use. To prevent pollution and ensure public health, waste water ought to be treated adequately. Today, waste water is not so much a problem as it was in earlier centuries, a trend that is attributable to the development of efficient sewer lines and treatment plants, otherwise referred to as centralized wastewater collection and treatment facilities. Not long ago, however, these were not as effective as they are today, and worse still, were not available to a majority of the population. People used the conventional decentralized waste systems to take care of, among others, the black waters, and still managed to lead hygienic lives.
Septic Systems: these consisted of a "septic tank, the drain field, and the soil beneath the drain field" (NCSU, 2013).…… [Read More]
These efforts include: expansion of international efforts to prevent terrorist acquisition of biological agents, initiated Bioatch program to detect initial releases of biological weapons within the environment, launched food programs to carefully inspect foods for potential bioagents (with greater focus on foreign foods), expanded bioterrorism research (including Project Bioshield, a program to develop medical ripostes to biological agents), and increased medical stockpiles and training for dealing with bioterrorism attacks (Cordesman; Lindler, Lebeda, & Korch; Petsko; Fidler & Gostin). These efforts will help to both prevent the initial release of any biological agents within the general populace or environment, as well as effectively treat afflicted individuals and slow spread through appropriate treatments.
Once biological agents are released into the general population, the extent of disease spread and number of individuals afflicted will be significantly affected by the role and effectiveness of the government through quarantine and treatment (Cordesman; Lindler, Lebeda, &…… [Read More]
Bioreduction will be most effective in the future if researchers and engineers can develop more effective means of delivering needed nutrients to the microorganism strands used in remediation efforts, as well as tailor site conditions as needed. In the final analysis, it seems most likely that a combination of extractive and immobilization techniques will produce the best results, by each removing aspects of chromium contamination that the other cannot effectively eliminate.

Monosodium glutamate, otherwise known as MSG, is a commonly discussed food additive used throughout the world today. While some countries use it minimally, and place high restrictions on its use, other countries use it on a consistent basis, in many foods. This paper will examine MSG, and its uses. Additionally, this paper will examine each step of how MSG is made, using fermentation. The discussion will include technical details of the process, the equipment commonly used, the use of enzymes and bacteria, as well as an examination of the product packaging and quality control procedures. Finally, this paper will include a brief description of the market of MSG, and the socio-economic aspects of the product.
Monosodium glutamate, or MSG, is the sodium salt of glutamic acid. Glutamate is an amino acid that occurs naturally in many foods known for their flavor, such as tomatoes and mushrooms. Additionally, glutamate is found…… [Read More]
Search of the Perfect Host
The Origins and Specificity of Parasites
The door opens. You walk into the room. You hear your favorite music. You see your best friends. Your favorite drink is waiting on the bar. Smiling, the hostess approaches, "I did it all for you." Ah, what a dream - the perfect party, the perfect host! While such a fantasy may not always be the lot of the human guest, it is real life for many microbial visitors. Every parasite has its "perfect host," the one organism that is ideally suited to its needs. Of course, this perfect pairing of guest and host did not evolve by accident. Over the course of time, parasites have evolved in tandem with the organisms upon which they live. It is a unique relationship, the host organism providing a complete environment for the parasite. The parasite has so completely adapted itself to…… [Read More]

Currently, the U.S. baking industry is a nearly $310 billion industry that has…… [Read More]
These are questions dealing with attitude and are the most important questions when doing qualitative social science research to gauge relationships among events. In addition to construction questions about attitudes, it is important to have the questions drafted in the correct format (Nachmias, 2008).
The Quantitative methodologies will be the statistical tests designed for the overall model to incorporate the information provided through one, two or all of the Qualitative data analysis methodologies. The tests used to determine the relationship between these "qualitative" factors and increases in Infection rates, will be the Chi-Square, Student's T-Test, ANOVA (to test for variations among the data), the construction of a Linear Regression Model and the calculation of the Pearson Correlation Coefficient, otherwise known as "R-Squared" (Nachmias, 2008).
These tests will be utilized in conjunction with a predetermined level of significance, or alpha. Since these tests will all be measuring the means and relationships…… [Read More]
This implies that decomposition process goes on activated by the young earthworms in the soil, given that the soil is loose, moist and rich in organic matter for the worms to remain alive. The bacterium which is present in the alimentary canal of the earthworm converts organic water to natural fertilizers. The chemical alterations that the organic wastes are put to consist of deorderising and neutralizing. This implies that the pH of the castings is 7 which is neutral. (the tasteful garden)
The Latin meaning of vermes is worm from which the term vermiculture has been derived. Vermiculture is a process wherein the process of composting, containing the addition of some species of earthworms used to improve the process of conversion of waste and produce an improve product. Vemicomposting varies from composting in a number of ways. Mainly, vermicomposting consists of a mesophillic process in which the microorganisms are…… [Read More]
positive and negative impacts of DNA microarrays, Genetic engineering and cloning on the society, environment and the living beings.
In the past years, people have heard much about the biological revolution and they have seen it coming too. Biology, with its modern discoveries, has not only influenced agriculture, medicine and economy but it has affected the nature of man as well. In today's era, where both, biology and technology are developing at a fast pace it is impossible for anyone to survive without having sufficient knowledge about science. The information related to scientific issues will enable the people to make good choices about their health, environment, surroundings and the society in which they reside. This information also enables the people to logically analyze different inventions and advancements in biology so that they can decide that whether the projected discovery is good for them or not.

iological Weapons: The 'Living' and Pervasive Weapons of Mass Destruction
The 'art' and methods of war have indeed gone a long way; from subsisting to crude metals and guns, human society has learned to manipulate Nature by using as one of its weapons of mass destruction organisms that create balance within the planet's ecosystem. Nuclear warheads, guns, and other artilleries and weaponry are no longer feasible arsenals of war, mainly because they are not energy- and economically-efficient, as biological weapons are. iological weapons, is identified as a destructive medium which "consist of living, infectious microorganisms that are disseminated as aerosols through the atmosphere... are generally invisible, odorless, and tasteless" (Falkenrath, 1998). These characteristics of biological weapons make it a feasible medium for destruction, especially between warring nations/societies.
This paper traces the origins and history of biological weapons, especially in the United States. In knowing its history, this research also looks…… [Read More]
"Individual odor thresholds range from 1 to 13 parts per million. Between 50 and 100 parts per million, it causes mild inflammation on the membrane joining eyeball and eyelid after an hour, loss of smell in two to 15 minutes and can burn the throat" (Lucas, ¶ 4-5). A person can tolerate a maximum concentration of 170 to 330 parts per million for approximately one hour without serious consequences. At 500 parts per million, however, the person loses reasoning and balance and possibly experiences respiratory disturbance. When a person is exposed to 700 to 1,000 parts per million for up to an hour, death may occur within minutes. Emissions In the journal publication, "A Guide to geothermal energy and the environment," Alyssa Kagel, Diana Bates, and Karl Gawell (2007), all of the Geothermal Energy Association, explain that the visible plumes rising from some thermal power plants consists of water vapor…… [Read More]
Another consequence of the exploitative use of water resources is the destruction of mangrove forests and the fragmentation of the habitats of endangered species. The United Nations Convention on International Trade in Endangered Species of Wild Flora and Fauna listed 189 endangered species in China among the 740 in the world.
Sand content is quite high in the Yellow iver. In the dry season, sand rises and flies up with the wind and soil desertization becomes severe. In addition, the iver's dri-up directly reduces the quantity of water for farmland irrigation. The supply of ground water decreases while the exploitation quantity of ground water increases. The results would include a deep crescent of ground water, a decrease of land evapo-transpiration, local climate drying, soil desertization, a reduction of biotic population and a simplification of biocommunity structure.
Another serious problem confronted in the Yellow iver is nitrogen contamination. A study found…… [Read More]
The following study suggests that whilst macro and micronutrients are conducive to plant growth it is water that has the greatest impact on, and is the most crucial regulator of plant growth and, when regulated, can lead to the highest growth spurt. The author of this study, therefore, wished to test the effects of a pellet, one of whose elements originated from a microorganism, powder that sourced from a microorganism, and water. The hypothesis was that whilst each would contribute to plant growth, the greatest amount of growth would emerge from the water and that even thoguh all plants in each of the other 2 studies initially received the same amount of water in their feeding / growth process, addition of water to the experimental study of the Brassica rapa would -- due to water's enhanced absorption capacities -- evidence enhanced plant growth.. Formulating these hypotheses in a scientific manner:…… [Read More]
Having known the mounting dangers, many public health and bio-terrorism experts, members of Congress and some well-positioned ush administration officials convey increasing discomfort about what they think are flaws in the country's bio-defenses. Over the earlier years, awareness steps have been made, mainly in the large cities. ut most of necessary equipments are not available.
The federal government's standard answer to the anthrax assaults of 2001 and the warning of upcoming bio-terror attacks has been to accumulate huge amounts of drugs and vaccines to take care of or vaccinate sufferers or possible sufferers. However, these medicines are ineffective if there is no dependable system in place to quickly distribute and give out them to the disturbed populations early enough for the drugs to be successful. Regrettably, as of now, we do not have this strong, competent system in position in the United States. At the close of 2003, only two…… [Read More]
living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.
iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.
Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

Microbiome can be defined as the sum of microbes, their genetic genomes and their environmental interactions in a particular environment. The word Microbiome was inverted by Joshua Lederberg, one of the giants of molecular biology to designate all microbes. He emphasized that microorganisms inhabiting the human body should be included as part of the human genome, reason on the influence on human body physiology (Predator, 2012).
However, microbes are seen to be the dominant life form of Earth. Its bacteria organisms which live on the plant are outnumbering all other bacteria combined. According to Joshua Lederberg, Microbiome bacteria dominate not only the planet, but also new people. However, the body of each one of us is ten (10) times more microbial cells than other cells which are contained in the human body (Predators, 2012). Therefore, the number of microbial genes in the human body is one hundred and fifty (150)…… [Read More]

Development of Two Important Materials in Earth's Early History
According to scientists, Earth began its life 4.6 billion years ago, when cosmic dust collided to form increasingly large particles. These particles, after millions of years of colliding and increasing in mass, eventually formed the Earth, with a mass similar to what it is today (5.9736 x 1024 kg or 5,973,600,000,000,000,000,000,000 kg) . Soon, the Earth's atmosphere began to form, as well as various minerals within its core. Studying the Earth is a fascinating endeavor, yet one that comprises extensive research and writing. For the purposes of this paper, I will examine two elements that are of vital importance to human life today: oil and gas. In this study, I will thus speak both about the development of the two materials in the Earth's early history-how they developed, what factors contributed to this development, and when this development…… [Read More]
Computers are being used in applications that gauge the pollution in the air and water and other areas of the earth environment. These applications are useful in determining the source of the pollution and in assisting in informing researchers what might be done to reduce such pollution.
Air Pollution Emission
One such application in computing pollution is described in the work of Emad, Sayed, and Kassem (nd)[footnoteef:1] who report that smoke is one common source of air pollution. Specifically stated is that the "rising process of smoke depends on atmospheric ambient, meteorological conditions, emission parameters, such as the atmospheric stratification, initial emission momentum and temperature, wind direction and speed as well as turbulent behaviors, and so on." (Emad, Sayed, and Kassem, nd, p.1) The smoke dilution process and scope are of great interest to environmentalists since regional air quality is affected critically by dispersion of pollutants. eported as…… [Read More]
Air pollution pertains to substances and gases in the air that threaten health and life. Among these are pollutants and irritants, such as nitrogen oxides, sulfur dioxide, and carbon dioxide; particulates, volatile organic compounds (VOCs), toxic substances and some natural substances, like pollen. ut most of the pollution comes from the by-products of industrialization - fossil fuel combustion, transportation, transportation, power plant emissions and those from other industrial processes. The burning of fossil fuels to generate electricity alone is the greatest source of air pollution in the U.S.A. These outdoor pollutants can undermine health and cause environmental disturbances, such as acid rain, and are toxic.

GENETICALLY ENGINEERED FOOD OR ORGANISMS: SCIENCE'S ANSWER TO WORLD HUNGER
The introduction and use of genetically modified or engineered foods or organisms have attracted attention, mostly alarmed in recent years (WHO 2014). These foods are manufactured from organisms by artificially altering or engineering their DNA for nutrition purposes. This is done by infusing an edible plant gene into the organisms for immediate and ultimate purposes. One is to optimize production and increase the resistance to plant disease while tolerating the harmful effects of herbicides. Another is to extract them from genetically modified or GM microorganisms or animals for future use. Still another object or prospect is to alter the nutrients themselves in foods in order to control or prevent allergies they cause (WHO).
The target of the United Nations Organization's Millennium Development goals is to cut down the proportion of hunger this year into half (World Hunger Education Service, 2015).…… [Read More]
Classification of Microorganisms
The world is rife and full of what are known as microorganisms. These microorganisms, also known as microbes, come in a number of different forms. Five in total, these groups are viruses, bacteria, algae, fungi and protozoa. It is important to know why these different groups are classified differently and what each of them do. As is clear to most people, these groups range from the harmless to the useful and even the dangerous. Some groups are combinations of two or more. This brief response will cover each of these at a somewhat detailed level. hile microbes are not visible to the naked eye, they certainly have an effect on our lives.
As noted in the introduction, there are five groups when it comes to microbes. A virus, at its heart, is a microscopic organism that is a tiny bundle of genetic material. That material is shrouded…… [Read More]
The shrub is fast growing and seeds can remain viable in the soil for as long as five years. It can lie in wait until growing conditions are optimum and then begin its life cycle. It can also spread via sucker propagation. The ability to do this is a key reason for the invasive nature of the plant. As buckthorn leaves fall to the ground, their leaves contain a high concentration of nitrogen, which can change the soil pH and create changes in the soil. This promotes the establishment of more buckthorn trees, but can create a hostile environment for other native plant species.
One of the key reasons why the spread of common buckthorn needs to be stopped is its ability to quickly create, starving other plants around it of needed light. It can prevent the generation of native plant species around it. However, this is not the most…… [Read More]
There are almost 60 programs accredited by the NAACLS for clinical assisting and phlebotomy. The Accrediting Bureau of Health Education Schools and the Commission on Accreditation of Allied Health Education Programs are two extra and relevant accrediting associations (Clinical Laboratory Technologist and Technician Career, Job and Employment Information, 2010).
Laboratory technologists and technicians must be licensed in order to be employed in a number of states; information concerning attaining the license is accessible from the State departments. Nongovernmental agencies, frequently a professional society, set principles and endorse those who meet or surpass their principles. Most companies in this field necessitate certification for new employees and for progression. Each business sets their own principles and is supported by diverse groups (Clinical Laboratory Technologist and Technician Career, Job and Employment Information, 2010). Lab technicians frequently must have a bachelor's degree and pass an examination in order to be licensed. Yet, the necessities…… [Read More]
According to Aiken, this liberation is only achieved after twelve years as a monk and eight rebirths. Souls who do not achieve liberation are either reborn as another life on earth or suffer punishment in one of the eight levels of hell.
Once a householder undertakes the path to liberation of the soul, according to the Jain Center of America, he must take and follow the five vows:
Ahimsa -- nonviolence
Satya -- truthfulness
Asteya -- not stealing
Brahmacarya -- celibacy or monogamy
Aparigraha -- detachment from material possessions 'All the venerable ones (arhats) of the past, present and future discourse, counsel, proclaim, propound and prescribe thus in unison: do not injure, abuse, oppress, enslave, insult, torment, torture or kill any creature or living being' (Uttaraadhyayan Sutra)

When organisms higher on the food chain -- like human beings -- eat plants and other organisms lower on the food chain, they absorb and utilize the nitrogen that was originally fixed by these bacteria (Harrison 2003). In this way, the nitrogen from the atmosphere is able to make it through the entire biosphere. The cycle is not complete, however, until the nitrogen is returned back to the atmosphere. This occurs when higher organisms die, and decay (as well as metabolic process of other bacteria and fungi) converts the fixed nitrogen back to ammonia, or even further into nitrates which will eventually break down further and become nitrogen gas again, returning to the atmosphere (Kimball 2008). Sometimes the nitrogen products of decay return to the soil or directly to plants, and other byproducts can actually build up to toxic levels in soil and in the world's oceans (Harrison 2003).

Given a mosquito's vastly shorter life span, preventing the spread of the infection to more human hosts greatly reduces the number of viable parasites in existence (CDC 2009).
There are several reasons that viral infections are more difficult to treat and diagnose than bacterial infections. For one thing, viruses are not truly alive, and this makes it difficult to kill them. They are essentially packets of genetic information in tough protein shells; there are no real biological mechanisms for medicines to disrupt. In addition, the virus' use of host cells as reproduction sites means that drugs used to attack the virus often als due damage to healthy cells and the body's natural defenses. The basic life cycle of an animla virus includes hijacking a host cell and reproducing until rupture, where the process continues in new host cells. Most viruses can remain viable indefinitely outside a host, so the…… [Read More]

There have been numerous E.coli outbreaks over the years. Pakalniskiene, Falkenhorst, Lisby, and Madsen (2009) studied one of the larger single source outbreaks. On November 11th, 2006, there was an outbreak in Greater Copenhagen, Denmark. The director of a high school had contacted the regional health authority to report an outbreak of diarrhea and vomiting among guests of a school dinner party. A total of 750 people, nearly all of the teachers and students at the school, had attended the dinner. The evening, the first people became sick. Three days later, when the director made the report, approximately 200 to 300 teachers and students had reported gastroenteritis. It was found that the fresh basil used in the…… [Read More]

" (Sukumaran, 2004) Mutation is what results in the difference and may be utilized as a measure of the time that has elapsed since separation of the species from the common ancestor during evolution. This is a method of "inferring the divergence of time of clades from a common ancestor by means of gene/protein sequencing" and has been termed 'molecular dating'. The process is one in which there is a calibration of time in comparison to the Phanerozoic era fossil data and then expoliation is conducted for providing the estimation time for divergence of phyla. (Sukumaran, 2004; paraphrased) Indeed, if life did evolve as posited in the work of Charles Darwin then "the abrupt appearance of diversified life at the beginning of the Cambrian period was not explainable." (Sukumaran, 2004) However, Sukumaran explains that gradualism is not a central tenet to the idea that there has been an evolution of…… [Read More]
S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…… [Read More]
But after local wastewater plants were "...upgraded and farms' management practices were improved, the amount of phosphorus declined and the copper sulfate was no long considered necessary" (Royte, 2007). The Times' story reports that to prevent the dumping of partially treated sewage water into the waterways, septic tanks need to be upgraded and "cleaning the water in sewage treatments plants even more thoroughly before it is discharged into the watershed..." is necessary. That will be quite a job, because "more than two dozen of the roughly 100 wastewater treatment plants that discharge into the city's watershed use a suboptimal cleaning process."

Natural Resources and nergy: Florida verglades
ffects of Agriculture
The verglades' freshwater ecosystem supplies vital services to the local population, such as the maintenance of South Florida's agriculture and drinking water (National Wildlife Preservation, 2012). However, these services are rarely accounted for in decision making in regards to land use and planning. As a result of the natural services being taken for granted, Agricultural scientists agree that modern agriculture faces an environmental calamity. Specifically, " the very nature of the agricultural structure and prevailing policies have led to this environmental crisis by favoring large farm size, specialized production, crop monocultures and mechanization" (Altieri, 2001).
The absence of diversifications and rotations of crops, necessary for the self-regulating process, induces the agroecosystems to rely on vast amounts of chemicals, such as fertilizer nutrients. Moreover, crops ineffectively absorb the chemical fertilizers, thus contaminating the surface and ground water. According to Altieri (2001), "In…… [Read More]
Plasma & BC
Plasma constitutes the majority of whole blood volume, about 46-63% (Martini, Nath, & Bartholomew, 2011). Plasma is the matrix of blood, contributing to blood's unique composition. Plasma has three main components: plasma proteins, water, and other solutes (Patton & Thibodeau, 2009). Plasma proteins are too large in size to get across capillary walls; therefore after the majority of these proteins are synthesized by the liver, they go into the bloodstream and remain there (Martini, Nath, & Bartholomew, 2011). The majority of plasma proteins are albumins. Albumin's role is to contribute to the osmotic pressure of plasma; they also serve as carrier proteins, transporting various hormones and fatty acids (Tortora & Derrickson, 2011). Globulin is another plasma protein whose role is to transport ions, thyroid and steroid hormones, and lipids; they also contain our antibodies that help our immune system (Martini, Nath, & Bartholomew, 2011). Fibrinogin is an…… [Read More]

Evidence-Based Solution to educing Incidence
The goal of this assignment is to increase my ability to appraise and synthesize evidence to provide experience a logical argument in support of a proposal for practice change, and to provide experience in designing a detailed implementation and evaluation plan for my project. I need to discuss my project plan with you.
An evidence-based solution to reducing incidence of hospital acquired infections through indwelling medical devices
Hospital-acquired or nosocomial infections are the fourth leading cause of disease in developed countries. The increased insertion and implanting of prosthetic or indwelling medical devices is a leading cause of these infections since the introduction of a foreign body significantly reduces the body's immunity and decreases the number of bacteria needed to produce an infection. Prosthetic or indwelling medical devices such as urethral catheters, suprapublic catheter, nasogastric tubes, hemodialysis catheters, central venous catheters, and tracheostomy tubes are associated…… [Read More]
Hazards on the Hudson
Imagine, if you will, a sunny day. A boy and his father are fishing on the beautiful waters of the Hudson River. Excitedly, the boy yells, "I got a fish! I got a fish!" He reels it in and his father removes the hook from its mouth. Dad says, "That sure is nice one, son." He then tosses the fish back in the water. hen the boy asks why, the father explains that the fish in these waters are dangerous to eat. They contain high levels of Polychlorinated biphenyls (PCBs).
Since the middle part of this decade, the GE Company used PCBs to pack and insulate their electrical components. During this manufacturing process they managed to dump millions of tons of dangerous chemicals into the Hudson River. Now the EPA has ordered GE to help clean up the mess they created. The legal battle has been…… [Read More]
Mold Spore Trapping
Current Scientific Knowledge
People are exposed to aeroallergens in a variety of settings, both at home and at work. Fungi are ubiquitous airborne allergens and are important causes of human diseases, especially in the upper and lower respiratory tracts. These diseases occur in persons of various ages.
Airborne spores and other fungi particles are ubiquitous in nonpolar landscapes, especially amongst field crops, and often form the bulk of suspended biogenic debris. The term mold often is used synonymously with the term fungi. A more precise definition would specify that molds lack macroscopic reproductive structures but may produce visible colonies. Respiratory illness in subjects exposed to rust and dark-spored imperfecti fungi was described more than 60 years ago, and physicians worldwide now recognize a sensitization to diverse fungi.
Since fungus particles commonly are derived from wholly microscopic sources, exposure hazards are assessed largely through direct sampling of a…… [Read More]
isk Analysis and the Security Survey
The following risk analysis and security survey report will be centered on the hospital as an organization. Vulnerabilities can be classified as crime opportunities, opportunities for breaking rules and regulations, opportunities for profiting and also for loss. By definition, vulnerability can be a gap or a weakness inside a security program that might be exploited by opponents to acquire unlawful access. Vulnerabilities include procedural, human, structural, electronic as well as other elements that offer opportunities to damage assets (Vellani and Owles, 2007).
A vulnerability assessment can be classified as a systematic method utilized to evaluate an organization's security position, assess the efficiency of current security infrastructure, as well as, recognize security limitations. The basic approach of a Vulnerability Assessment (VA) first measures what precise assets require protection. Subsequently, VA recognizes the protection measures previously being used to protect those assets, as well as what…… [Read More]

The purpose of this document is to provide recommendations to assist Mcdonald completing the Green Sourcing process for French fries. The report uses the following steps in providing the…… [Read More]
Polymicrobial Diseases of Animals and Diseases
Identify the research hypothesis and re-state it
The research hypothesis is that polymicrobial diseases found in animals as well as human beings are instigated by polyviral contaminations, polybacterial contaminations polymicrobial contaminations that involve viruses and bacteria, polymicrobial infections that involve fungi and parasites and polymicrobial infections owing to microbe-induced immunosuppression. These aforementioned illnesses are severe and whose etiologic causes are every now and then challenging to diagnose and treat.
What is the major issue at the heart of this publication?
The key issue at the core of this publication is the discussion of polymicrobial infections, particularly in human beings and animals. It also takes into consideration the etiological causes and the fundamental mechanisms of pathogenesis. It is imperative to note that polymicrobial illness is a fast developing and exceedingly studied field, yet at the same time signifies an ignored concept. Therefore, this article delves…… [Read More]
She is said to have refused to stop being a cook and this led to infection of people in a New York maternity hospital consequently she was re-arrested by the health officers and taken back to quarantine in 1915 till her death in 1938. This sparked a lot of human rights issues concerning quarantine as never before.
The typhoid pandemic in New York went hand in hand with the poliomyelitis pandemic that began in 1916. The health officers began to separate parents from their children in chagrin of many. This saw the wealthier families provide isolation rooms and treatment for their children right at home. However, in November of the same year when the pandemic subsided, it was after well above 2,300 lives claimed by the pandemic, a vast majority being the young.
It was not long until the world war brought with it another challenge of prostitution and consequent…… [Read More]
The development of a bio-economy capable of supplying the world's energy demand is where the synthetic biologists wish to take this the next step. Additionally, biologists are able to develop a sort of biological acolyte from the principles of synthetic biology, involving synthesizing DNA in combination with the raw building blocks of genetics. A new platform for different biological life form is essentially, what these biologists have discovered.
According to commission chairwoman, and the president of the University of Pennsylvania, Amy Gutmann, "Here's something significant in science, but there's no cause for fear and dread about what is going to happen immediately next." The commission report recommended greater ethical constraint and greater collaboration. Amy Gutmann, further states that ethics training be mandatory for all researchers in the field.
Opponents of the report include Brent Erickson, an executive in the biotech industry. According to the New York Times, Mr. Erickson called…… [Read More]
Authors present the results of a national law enforcement technology survey and comparable forensics technology survey that was conducted by the RAND Corporation to assess the effectiveness of this support and constraints to applying forensic technologies at the state and local level. Authors devote several chapters to different types of forensic analyses, including what types of techniques are best suited for various types of crimes and the evidence that may be present. A discussion concerning the types of evidence, including controlled substances, firearms, explosives, fire debris, bullets, footwear, vehicle tire marks, latent fingerprints, blood, gunpowder residue and so forth that are typically encountered in different crime scenes is followed by a useful description concerning how and why specific forensic technologies are used. Authors also present a description concerning how computer-based technologies are facilitating the application of these forensic investigatory methods to achieve higher conviction rates by providing improved testing results.…… [Read More]
Japan, Russia, South Korea and countries that are members of the European Union require that genetically modified food products be labeled accordingly. (Li, Curtis, McCluskey, and Wahl, 2002, paraphrased) in fact, it is reported that China along with 160 other countries have signed the 2000 Cartegena Protocol on iosafety, stated to include a requirement for labeling of GM products.

The work of Finucane (2002) entitled: 'Mad Cows, Mad Corn and Mad Communities: The Role of Socio-Cultural Factors in the Perceived Risk of Genetically Modified Food" published in the Journal of the Proceedings of the Nutrition Society" states that the "rapid globalization of the world economy has increased the need for a knowledge base of relatable socio-cultural differences in perceptions, values and ways of thinking about new food technologies." (Finucane, 2002) Finucane (2002) states additionally that the awareness…… [Read More]
Why are fat-soluble drugs more suitable for this type of delivery than drugs that are soluble in water?
Fat-soluble drugs are more suitable for skin diffusion than soluble drugs because they tend to be hydrophobic compounds, which facilitates their diffusion across the lipid membrane of skin cells. Water-soluble drugs are often hydrophilic and thus cannot easily diffuse through a hydrophobic milieu like the plasma membrane.
5. Which cutaneous glands are associated with hair follicles and what is their function?
The sebaceous glands are associated with hair follicles and function to secrete sebum (oil-like composition) into the follicular canal. Sebum helps to waterproof hair and skin, and it also serves to prevent cracking due to dehydration.
6. In which layer(s) of the epidermis does cell division occur?
Cell division occurs primarily in the stratum basale.

Gray Water System
As the world's population continues to grow, there will be an ever greater need for potable or purified water. Most people are completely unaware of just how big the problem of world water consumption is because they never think past turning on their sink or sprinkler system. Take into consideration the demands on the water supply by less obvious factors such as livestock and farming. There is an economy of scale: those massive agricultural irrigation systems that suck water out of rivers, lakes, streams and ponds consume hefty amounts of water that cannot then be used for any other purpose. Farms, cities, industry and the many other levels of human consumption place a great deal of pressure on Mother Nature. Globalization has actually increased the demand for water and has strained many regionally dry areas into even worse water deficits. For example, "industries and communities located in…… [Read More]
The Gold Coast area has a reputation as a flood prone area, even without considering the effects of global climate change.
The Gold Coast area comprises seven major catchment areas including the Tallebudgera, Currumbin, Nerang iver, Coomera iver, Pimpama iver, South Moreton Bay, Sandy Creek and Broadwater area (Mirfenderesk, 2009). The Nerang iver catchment is adjacent to the Tallebudgers catchment to the South. It is bordered by the Broadwater and Coomera iver area to the North. The Nerang iver catchment is adjacent to the Pacific beach area as well (Mirfenderesk, 2009).
Catchment areas have different levels of tolerance before the concentration of water to sediment reaches saturation levels, creating the likelihood of flooding in the area. The Tallbudgers, Currubin, and Broadwater area have time concentrations of approximately 3 hours, creating conditions favorable to short duration local flooding (Mirfenderesk, 2009). The Nerang iver and Coomera catchments have time of concentrations from…… [Read More]
