Ocean Water Modifies and Influences

Words: 3103 Length: 10 Pages Document Type: Essay Paper #: 16827822

The larger particles can influence the absorption rates of solar energy by a factor of three over particulates such as phytoplankton and minerals (Stramski and Woz'niak, 2005). This means that a small concentration of these particles can do a lot for the absorption rates of the water they are suspended in. The smaller particles can also have this effect, but their concentrations need to be proportionately higher to exact this same influence. The smaller particles are more influential as far as backscattering is concerned, and represent a massive shift in the way that scientists think about light diffusion and backscattering within the ocean. Previously, scientists thought that only the larger of these particles combined with other particulates were responsible for most of the solar radiation absorption (Bricaud, a., Morel, a. And Prieur, L., 1981). Now scientists understand that in shallow, mineral-rich waters, even a small presence of these tiniest of…… [Read More]

Occupational Health and Safety There

Words: 4258 Length: 14 Pages Document Type: Essay Paper #: 39413158

Combined with the human development index these studies showed that using parameters that affect the standards like education, longevity, and standard of living it is possible to predict the environmental health factors, and find the actual health indicators. (Corvalan; Briggs; Zielhuis, 2000, p. 159)

The first problem is the distinguishing between health promotion and health education. Work place health actions tend to be concerned about disease prevention. So far it was up to the institutions to take care of workplace hazards. There were no proper evaluation methods. In Britain safety and health was not given any importance and this trend is changing with the claims filed by employees for damage. Today employers are more concerned with health issues, and health promotion has gone beyond occupational health promotion. (Wilkinson, 2001, p. 50) the management of risk begins with the evaluation of the risk qualitatively and quantitatively. The quantitative analysis of risks…… [Read More]

This has been the traditionally used mode of treatment for non-Hodgkin's Lymphomas, but the fact remains that there have not been many clinical trials conducted that would reveal the benefits of CHOP in comparison to various other chemotherapy options for the treatment of CLL, which is a very slowly growing form of cancer and is therefore conversely very difficult to treat and cure because of the fact that all the traditional methods of treatment, whether chemotherapy or radiation, are meant to quickly and rapidly destroy the fast growing cancerous cells. (Cancer Treatment and Prevention)

Curing a patient with the CLL or SLL forms of cancer is considered to be highly unusual, but it is true that these patients will b able to lead productive lives even after 6 to 10 years after the cancer have been diagnosed for them.

Histone H2AX in the Study

Words: 5478 Length: 15 Pages Document Type: Essay Paper #: 64159440

These proteins include homologous members of yeast. The presences of these proteins suggest that E. histolytica is skilled to perform homologous recombination, which is the same as in other organisms. DNA damage was evaluated by TUNEL assay. In yeast and in human cells, histone H2AX becomes rapidly phosphorylated when DSs are introduced into chromatin (Lavi et al.).

Studies show that histone as a protein plays a significant role in the transition between the expression of a fetal gene and that of the adult gene. The adult gene's metabolism becomes oxidative in order to adapt to air and to weight, as it generates methylated transmitters and creatine phosphate. The muscles get used to life on the ground as compared to the fetal life which takes place in an aquatic environment. Regulated proteins allow the muscles to respond in a more adequate manner to this environment.

Now, let us see how histone…… [Read More]

rapid movement of the modern age and the vast usage of technological equipment, it has become a constant question on whether radio frequencies are damaging to human health. Cell phones are known to emit relatively high doses of electromagnetic waves, which in some research, has been pinpointed to the adverse effect that it has on males, namely the issue on fertility. eports have been made indicating that cell phones might be another risk factor regarding the rise of male infertility due to its frequency emissions. While previous research has found no conclusive tie-ins to the phenomena, the latest technology and data have shown the contrary, though even this research is still subject to much scrutiny. Overall, there are too many variables to indicate that cell phones would be a main cause for male fertility, not without discussing the various other factors that help infertility along.

There have been rumors relating to the fact that the authorities might have lied concerning the number of curies released and that it had actually been much bigger.

hile the initial communications from the authorities advised people not to panic and that the situation had been under control, the later reports informed people that precautions needed to be taken. Several tens of thousands of people had been evacuated from the area within a few days and the surrounding schools had been closed. According to surveys done consequent to the event, people apparently considered that the job done by the authorities had been deficient.

According to the studies performed in order to determine the level of radiation exposure, people had not been subjected to life-threatening doses of radiation. The average dose of radiation to which people have been subjected to consequent to the TMI incident is believed to be eight millirem.…… [Read More]

Sinmed Shoulder Support Cushion for Head and Neck Immobilisation

Brown's (2010) article entitled "Evaluation of a Sinmed Shoulder Support Cushion for Head and Neck Immobilisation," published in The adiographer, investigates the efficacy in positioning for head and neck patients, with the Sinmed shoulder support cushion, as opposed to standard protocol in place at the Princess Alexandra Hospital adiation Oncology Department. Understanding that the ability to accurately position a patient is critical to successfully delivering radiation therapy treatment, Brown notes that the hospital has been investigating optimal immobilisation techniques. The author discovered that after trialing the Sinmed shoulder support cushion, manufactured by CIVCO Medical Solutions, no significant differences were found in the positioning accuracy, from the standard protocol.

A small group of patients were trialed for this evaluation of the Sinmed shoulder support. Electronic portal imaging was used to asses the device, as well as a collation of observations that were…… [Read More]

Toxcio's experts, on the other hand, believe that evidence is incomplete and that further, costly studies need to be implemented to show the connection.

It seems to me that (a) if the biophysicist is indeed as credentialed and qualified as said and (b) if her studies are as empirical as stated from peer-reviewed scientific journals, bearing reliable evidence, than the families do, indeed have a case. This is because even thoguh further research may need to be conducted (as per Toxico's scientists) to assess strength of the research, the evidence that exists at the moment seems to show an almost undisputed association between the children's cancer and the toxic emission.

Nina Jablonski breaks the illusion of skin color (TED2009, 2009)

Nina Joblonski opens by commenting on Darwin's pigmentation and his upbringing. She further speaks of his voyage on the Beagle and his interest in the pigmentation of humans. Darwin did not believe that there was any correlation to skin pigmentation and climate. However, Joblonski points out that if Darwin had access to NASA satellites that he may have come to a different conclusion. One of NASA's satellites has capabilities to monitor the Earth's radiation close to the surface. As a result, researchers today have been able to study skin pigmentation and the exposure to solar radiation and find that there is a perfect gradient and strong correlation between the two.

Therefore, skin color is a product of evolutionary forces as human adapted to their environments and their skin adapt to the levels of radiation that…… [Read More]

Geology

(1) Discuss which of the interrelationships between the environmental spheres, in your experience, has had the biggest effect on human society, or vice versa. Give some examples.

The work of Manahan (2005) explains that there are four traditional environmental spheres including the hydrosphere, atmosphere, geosphere and the biosphere. It is related however, that a fifth sphere should be included and that is the anthrosphere, which consists of "the things humans make and do." (Manahan, 2005) The atmosphere is reported as a very thin layer compared to the size of Earth, with most atmospheric gases lying within a few kilometers of sea level. The atmosphere serves a vital protective function in that it absorbs highly energetic ultraviolet radiation from the sun that would kill living organisms exposed to it.

A specifically important aspect of the atmosphere is that the atmosphere serves a vital protective function in that it absorbs highly…… [Read More]

Solar Stills Limitations of Solar

Words: 371 Length: 1 Pages Document Type: Essay Paper #: 10865444

A light insulation causes a reduction of 14.5% in the efficiency obtained with full insulation. The wind effect is much more limited. The increase of wind velocity from zero to 3.6 mph yielded a slight reduction (2%) in the still performance.

Repeated tests have shown that the higher the operating temperature of the still, assuming insulation is equal, correlates with higher efficiency. For example, with each 6 degrees Celsius increase in ambient temperature, a still's output increases 7-8%. The application of this finding means that a still operating in a hot desert climate will produce typically as much as one-third more water than the same unit would produce in a cooler climate.

Production of distilled water is also associated with the thermal efficiency of the still itself. Efficiency may range from 30 to 60%, depending on the construction of the still, the amount and type of insulation used, ambient temperatures,…… [Read More]

Solar Flares Affect Planet Earth

Words: 953 Length: 3 Pages Document Type: Essay Paper #: 40201405

The last major x-ray flare occurred in 2003 ("O'Dell). Most of the energy from an x-ray flare is absorbed by the earth's ionosphere ("O'Dell). Thus, a CME can be far more dangerous for human societies than an x-ray flare.

The first and most subtle observable phenomenon signaling an upcoming solar storm are known as coronal loops, which are "kinks in the magnetic flux form" forced to the surface of the sun due to a buildup of magnetic energy (O'Dell). Dark spots on the sun's surface then appear, usually in the "footprint" of the coronal loops ("O'Dell). The dark spots visibly signal the buildup of magnetism. NASA describes the phenomenon of solar flares as occurring in three stages: a precursor stage, an impulsive stage, and a decay stage. During the precursor stage, the release of magnetic energy is only triggered and leads to "soft x-ray emissions," ("What is a Solar Flare?").…… [Read More]

Evolution of the Feather and the Origin of irds

THE EVOLUTION OF THE FEATHER AND THE ORIGIN OF THE IRD

This is a paper that explains about the origin of birds and the actual evolution of the feathers. The paper details about the way the feathers had first evolved and the way these birds had their origin. The common belief that the dinosaurs are the ancestors of these birds has been analyzed and the paper also deals with as to how the feathers of these birds would have developed.

The origin of feathers is unknown. Scientists have researched on this topic but none of the theories have even come close to being proved. In the past five years there have been efforts to answer as to the real evolution of these feathers. The mystery of the evolution of feathers is closely linked with the origin of birds themselves.

Mechanisms of Heat Loss Heat

Words: 870 Length: 3 Pages Document Type: Essay Paper #: 84441849

The above equation can also be utilized to calculate conduction loss from a human body to ambient air. For example, for a 1.5 tall man wearing dry, insulating clothing, the rate of conductive heat loss on a cold day (ambient temperature at 0oC, normal skin temperature at 37oC) can be calculated as 178W. For the same person wearing wet clothing, however, the equivalent rate is 2,565W. This significant difference in heat losses explains the onset of hypothermia when someone is exposed to ice-cold water or rain (Forinash, 2010). Conduction takes place on a microscopic level as particles of kinetic energy are transferred between two different systems (Abbott, et al., 2005). When atoms and/or molecules heat up, vibrate, or move rapidly, some of their energy gets transferred to other atoms and molecules that are in close proximity. In other words, heat is transferred to the surrounding particles and away from the…… [Read More]

Weapons of Mass Destruction and the Next Terror: Assessment of How a Significant Terrorist WMD Attack Might e Conducted by a Non-State Actors Perpetrator and Why They Can't Stage an Attack

Weapons of Mass Destructions (WMD) have considerable effect to the economies of both developed and developing countries. In the modern world, most terror groups have resolved to use Weapons of Mass Destruction to harm their enemies. The entire syndicate comprises state actors and the terror group, which intends to destroy the target country. The state actors have direct links or channels of communication with such attackers, foreign allies, and several residential alliances with almost similar connections to the terror groups. Most of the terror groups lack essential materials that would aid in the making of some of the most dangerous weapons such as nuclear bombs. The various forms of attack involved when using lethal weapons include dispersion, dissemination, and…… [Read More]

Yalom Analysis

The case surrounds Carlos, a man in his late 30s with a growing tumor that will not respond to radiation or chemotherapy. Carlos has been fighting this cancer for about a decade, but it is now to the point in which medical science can do no more for him. Carlos was referred to therapy by his oncologist, and responded somewhat to individual therapy but became combative and confrontational in group therapy. Carlos is a classic narcissist and misogynist. He has few friends, is estranged from his children, and is, at best cynical and sarcastic. However, through individual therapy, Carlos was able to come to some conclusions about the walls he built around himself, and the tremendous insecurity he harbored; typically using sex and sarcasm to cover up his need to belong. He eventually revealed that he had come up with two insights about himself and his relationship to…… [Read More]

Neuroendocrine tumors (NE) are neoplasms characterized by tissue immunoreactivity for neuroendocrine differentiation markers, appearance as a small mass that can be off white to yellow often in submucosa and prevalence throughout the body but typically found in the intestine or lungs (Oberg2011). he tumors can be malignant and are typically detected through hormone markers in a first diagnosis (Arnold 2003). Because of the diffuse nature of this type of tumor, detecting and imaging NEs requires scanning and typically requires a contrast agent to detect the location of tumors in tissue (an 2011). Many NE cells possess an overexpression of somatostatin receptors on their surface (Kwekkeboom 2005, VenEssen 2007). Somatostatin receptors are cell surface proteins that bind to somatostatin, a growth hormone inhibiting hormone that regulates the endocrine system and affects neurotransmission and cell proliferation (Florio 2002). he overexpressed somatostatin receptors can be used to both…… [Read More]

SOP I Stood by My Younger Sister

Words: 995 Length: 3 Pages Document Type: Essay Paper #: 95851939

SOP

I stood by my younger sister when she fell from the giant tree in our backyard, her leg twisted behind her. She was crying, but I was doing my best to hold back my tears to help her feel strong. At the hospital, the first sign that I would eventually follow a career path in radiology became clear. I saw my sister's x-ray. It looked exactly like the x-rays I had seen on television but with one big difference: this was the x-ray that belonged to someone I knew, and it was with this magical document that the doctors were able to piece my broken sister back together. My decision to be a radiographer was not an immediately transparent one, though. I did not then and there become determined to be a radiological science professional. Instead, the experience planted a seed. This seed has since been nurtured and is…… [Read More]

Atomic Testing Though Modern People

Words: 11346 Length: 35 Pages Document Type: Essay Paper #: 33269463



The First Nuclear Test

Of course, the first nuclear test occurred before the 1950s and was part of the United States' effort to develop an atomic weapon during World War II. This test occurred at 5:30 A.M. On July 16, 1945, at a missile range outside of Alamogordo, New Mexico. Even that test was enough to convince a large group of scientists that the atomic weapon was a dangerous and powerful weapon. "The Franck Report," a petition issued by Leo Szilard and 68 other scientists urged President Truman to first demonstrate the capabilities of the atomic bomb before using it as a weapon against the Japanese, because of the mass destruction that came with the bomb.

This test, known as the Trinity Test, was a tremendous success. "The energy developed in the test was several times greater than that expected by scientific group. The cloud column mass and top reached…… [Read More]

physical agents that exposes health and safety hazards to workers within the work places. Some of the physical agents are noise, vibrations, explosive atmospheres, electromagnetic fields, ionizing radiations as well as optical radiation. It should be noted that there are huge risks that are associated with these physical agents and unless measures are taken to contain the situation, serious health and safety risks may occur. There are also a number of directives that have laid down the minimum requirements aimed at protecting the workers.

From this report, it has been noted that the various hazards that are associated with the construction work include dust, hard physical labor, vibration, chemical vapors, radon as well as atmospheres lacking oxygen. Similarly, construction work is always done in pressurized environments. Therefore, underground casuals are exposed to serious risks as well as fatal injuries. Other physical hazards are exceptional as far as underground work is…… [Read More]

Desiccation Tolerance in Prokaryotes

Words: 5347 Length: 15 Pages Document Type: Essay Paper #: 11735432

Desiccation Tolerance in Prokaryotes

Water is very important for life. Indeed, the processes of life, both external and internal even, at the cellular and the molecular level, are governed by water. Without water, most living organisms suffer from what is known as water stress.

This water stress can be due to the loss of water or dehydration. Desiccation is a special case of dehydration where drying takes place in air. Alternatively, another form of water stress is due to the excessive accumulation of salts. This is relatedly called osmotic stress. Osmosis seeks to reduce this accumulation by moving fluids across a concentration gradient. While most living beings cannot survive without water, lesser species belonging to the eukarya group -- that includes both bacteria and a more primitive organism archaea show remarkable tolerance to water stress.

Responses to water stress takes place at a supracellular level as well as a cellular…… [Read More]

Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability

This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be the best solution to climate change. Given the threat posed by climate change, it makes sense that nuclear power would be increasing in share, not decreasing. This esearch proposal seeks to look at some of the issues facing nuclear power, and how it can overcome these issues to increase share going forward.

As a brief description, Fukushima Dai-Ichi Nuclear Power plant was an operating energy facility in Japan particularly in the Fukushima prefecture or province. The plant was established in 1971, which occupied a total of 3.5-kilometer site that makes it as one of the largest nuclear power plants in the world by land area. This nuclear power plant was very useful in the Japanese energy regulation system because it has an economical generation costs that is more reliable than using hydroelectric power sources from dams and streams. It is operated by Tokyo Electric Power Company that is the largest operating agency around Japan as claimed by Arnold (2010).

Diagnosis and Treatment Options for Pancreatic Cancer

Words: 2844 Length: 9 Pages Document Type: Essay Paper #: 93529969

Etiology of Pancreatic Cancer

Pancreatic cancer has emerged as the most lethal human cancers. In fact, the World Health Organization (WHO) has termed it an unresolved health problem of the 21st century. The disease presently causes about 30,000 deaths in the U.S. per year (Yarbro et al. 2015). Despite past efforts, conventional interventions like radiation, surgery, chemotherapy and combination of these had minimal success in the course of this aggressive disease. It is imperative to develop an in-depth understanding of the molecular biology of pancreatic cancer to help us effectively diagnose, prevent and treat the disease. Nearly all pancreatic cancer patients experience metastases and die due to the frustrating metabolic effects of their unrestrained growth (Shrikhande et al. 2010). Hence, a crucial requirement for progress is the establishment of effective systemic interventions, can reverse the aggressive biology of the disease.

According to the WHO, pancreatic cancer is the fifth most…… [Read More]
