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.

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]. Cell Phones Can Cause Cancer. Are Cell Phones Safe? Three reasons to support my position are: RF and Consensual Dangers. While mankind has somewhat grasped the ability to harness the power of electricity, new information and data is being understood to have new developments on how it may be harmful to one's health.

The purpose of this essay is to discuss the impacts and qualities of radio-frequency F exposure to human health. This essay will first give background information on the subject to help explain the mysterious nature of both electricity and magnetism that is strongly connected to this possible health risk.

The essay will then investigate empirical example and produced a review of literature pertinent to the topic.

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. Introduction 1 Topic Overview 7…… [Read More].

The next question that this essay will address has to do with some of the issues that were seen above, including faulty design and management procedures.

These are imperative questions to pose and answer if one is to successfully utilize nuclear technology for positive advancements. Often times, managers do not understand how an office truly works. It is, for this reason, necessary to apply examples to certain situations to prove to a manager that working people, especially with regards to computer, need a good workspace. Often, however, one finds that many computer workers have postural problems, and these are due to ill selected furniture, especially chairs.

Good quality chairs are expensive, but if one is to truly respect and aid his workers in maintaining and constantly putting out good outputs, one must ensure quality, as well as practicality. Thus, workers could find ways in which to convince the manager to implement solutions in order to aid them. Such a way could be to request the help of HR or of an individual who has sway with the manager.

If the manager is in office rather than off-site, the workers could group themselves and request an appointment. It is by working together that they can achieve a final and lasting solution.

Tim and Gale Publishing, Application of non-conventional and renewable energy sources. It is a radiation therapy technique in which non-uniform fluence is delivered to the patient from any given position of the treatment beam to enhance the composite dose distribution.

The clinical application of IMRT requires at least two systems; a a treatment-planning computer system for calculating non-uniform intensity maps for multiple beams coming from different directions to deliver higher dose to the target volume while protecting normal structures, and b a system of transferring the non-uniform planned fluences.

Each of these systems must be adequately tested and commissioned before actual clinical use. The treatment-planning system divides each beam into a large number of smaller beams beamlets and determines optimum setting of their fluences or weights. The optimization process involves inverse planning in which weights or intensities of the beamlet are automatically adjusted to achieve predefined dose distribution criteria for the composite plan.

These include transmission blocks, compensators, wedges, dynamic jaws, multileaf collimators, tomotherapy collimators, moving bar, and scanned elementary beams of variable intensity. Of these, only the last five allow dynamic intensity modulation. Wedges, transmission blocks and compensators are manual techniques that are inefficient, time consuming, and do not belong to the modern class of IMRT systems. Dynamic jaws are suited for applying wedge-shaped distributions but are not significantly superior to conventional metal wedges.

However, scanning beam may be used in combination with a dynamic multileaf collimator MLC to get rid of this problem and provide an additional degree of freedom for full dynamic intensity modulation. The case of dynamic MLC with upstream intensity modulation is a powerful but complex technique that is currently available only with scanning beam accelerators such as Microtrons. Also three-dimensional image data, image registration, and segmentation are all needed when planning for IMRT.

For each target planning target volume PTV , the user enters the plan criteria: Depending on the IMRT planning system, the user may be required to enter other data such as beam directions, beam energy, number of iterations, etc.

The isodose distributions are usually evaluated by dose volume histograms. Physical or dynamic wedges are commonly used to achieve homogeneous dose distribution in the tumor or PTV. To overcome the effect of formation of over dose regions, a manual forward planning method has been used.

In this method, two more beams with multi-leaf collimator MLC of different dose weights are added in addition to the main used beams in the major plan and sometimes; when we use the FIF technique, we can dispense the physical and dynamic wedges. FIF technique allows us to use additional MLC fields to achieve better homogeneity in dose distributions. So, in this study we used the FIF technique in the all three sites under study brain, prostate and left sided breast tumors because it can get us a homogeneous dose distribution in the PTV and decrease the dose hot spots in the treatment planning.

But naturally, there will be some dose hot spots in the plan. The regions of hot spots will be covered with the new segmented beams by editing in the MLC.

A small radiation dose weight was given to these smaller fields, and the plan was recalculated. Radiation interactions result in the creation of light photons. Goal is to measure the amount of light created and light created is proportion to radiation energy. The photons can be detected using the correspondent radiation frequency because they carry energy corresponding radiation spectrum.

Both radiation detector and photon detectors can measure the frequency of the radiation. The radiation detector is used to detect ionized particles of radiation while photon detector id used to detect light.

Photon detectors count proton of light and absorb them while radiation detector measures the energy of the radiation. They overlap when measuring radiation frequency. Worksheet On Radiation Essay. Harvey Mudd College Type of paper: This essay has been submitted by a student.
