ACTS AND POLICIES In this assignment I will explain the legal‚ ethical and operational issues in relation to the use of information. Legal issues Legal issues are various items of legislation (law) to protect the use of business information. Data protection act 1998 Many business store information about people‚ whether it’s for potential customers or previous clients. The data protection act protects the information held about people from being misused. The information businesses store

Angel Houston May 2‚ 2012 Will Restricting U.S. Carbon Emissions Damage the U.S. Economy? An important issue affecting the world today is climate change due to the increase in the amount of greenhouse gases that is released into the atmosphere. Greenhouse gases are gases that accumulate in the atmosphere due to human activity and the earth’s natural biological and chemical processes. The four major greenhouse gases are carbon dioxide ‚ methane‚ nitrous oxide‚ and fluorinated gases (U.S. Environmental

screening to for the image needed. With this application the target tissue must absorb the compound that contains the isotope; one of the most popular used isotopes for scans is Technetium -99m‚ this isotope last only for a period of time. Positron emission tomography (PET) is another technique used. With the radiation therapy this is the method used to treat cancers‚ to apply this treatment a boron-11 isotope solution is placed within the tumor which bombards it with neutrons; particles are only produced

Biological Approach to Depression The biological approach is based on the idea that depression has a physical or organic cause. One explanation suggests that some people are simply more genetically inclined to develop depression‚ as Hecimovic suggested that it was caused by a mutation in the 5-HTT gene‚ which was responsible for coding for serotonin production‚ and that this mutation is inherited. Family studies‚ twin studies and adoption studies have all helped support the role of genetics in

Electroencephalography (EEG) * electrical – v high temp reso‚ relatively poor spatial Indirect measures Neural activity consumes O2‚ generate electrical signals – compensate for O2 consumption – more oxy blood pumped into region 1. Positron emission tomography (PET) * radioactive isotopes (O2 15) injected – areas of brain which take up more = more active than other areas * measures blood flow 2. fMRI * measures rel amount of oxy blood flowing to diff parts of brain - oxy blood =

There are several methods that both measure and scan the cortical functions of the brain and they both have their individual strengths and weaknesses. In a Positron Emission Tomography (PET) scan the scanner injects the patient with glucose containing radiotracers which are radioactive and emit positrons which are then picked up by the scanner. As glucose is used for energy in the body it will travel to the brain and distributes itself to the parts of the brain need it most at that time. When it

How did the corporate culture of Enron contribute to its Bankruptcy? Once a sound company listed in fortune 500‚ Enron‚ lead to downfall because of deceptive accounting system incorporated within the organization. Enron’s dubicious finance finally collapsed in Dec 2‚ 2001 as it filed Bankruptcy in New York Bankruptcy court. The corporate culture of Enron focused on financial performance neglecting the stakeholder’s value .The relentless emphasis on the importance of the shareholder’s value created

used to trace the movements of certain substances around plants. An example of this is carbon 14. Carbon 14‚ a radioactive isotope‚is added to the carbon dioxide supply of the plant‚ to study the movement of products of photosynthesis. Positron Emission Tomography (PET) uses a camera to detect gamma rays emitted from the body and to pinpoint their exact location. Disease may be indicated if an organ takes up too much isotope‚ or not enough‚ or if there is an unusual pattern or rate of movement

Physics improves our quality of life by providing the basic understanding necessary for developing new instrumentation and techniques for medical applications‚ such as computer tomography‚ magnetic resonance imaging‚ positron emission tomography‚ ultrasonic imaging‚ and laser surgery. In summary‚ for all these reasons‚ physics is an essential part of the educational system and of an advanced society. We therefore urge all governments to seek advice from physicists and other scientists

There is a difference between the two options but every test suits a different research. Positron Emission Tomography (PET) scans detect changes of blood flow in the specific brain regions. PET scans are not the greatest on temporal resolution. The purpose of a PET scan is to correlate the changes in blood flow patterns during specific activities. The
