Positron emission tomography

Yet, we are still polluting our atmosphere and oceans at an all time high rate. What we need is a net zero emission. This is possible. We need the United States government to implement a plan to have zero gasoline and diesel powered vehicles on the road. Pollution regulations need to be raised on businesses. Finally, the way our homes and businesses are powered…

Air pollution has been a growing concern in the New England area over the past few decades. Air pollution can come from many different sources including stationary sources like factories and power plants, mobile sources like vehicles, agricultural sources found from gassy animals and their waste products, as well as natural sources like wildfires, dust storms and other natural occurrences. Various cities around New England have identified the sources that are contributing to the air pollution…

Air Act (CAA) is an environmental law made by the U.S. government. This federal law aims at regulating air emissions from stationary sources such as industries and mobile sources such as vehicles. It was established to authorize the Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) that protects the public health through regulation of emissions that have a hazardous effect on air (Sueyoshi & Goto, 2010). The CAA was established in 1963 after…

In his article, Jack Minz contends that current government policies of taxation are ineffective in reducing greenhouse gas emissions. He begins by discussing the failure of the Canadian government to reduce greenhouse gas emissions by six percent between 1990 and 2012, as promised during the 1997 Kyoto protocol. At the time this article was written, with policies of tax giveaways and subsidies failing, the Liberal party leader Michael Ignatieff promised a system of carbon taxation if elected.…

Cap and Trade Cap and trade is a system in which economically and an environmentally approach to control the emission of green house gases. Cap and trade is a market based approach to control pollution which was adopted by many countries, states, and groups of companies. The cap sets a limit on emissions, which is lowered over time to reduce the amount of pollutants released into the atmosphere. The trade creates a market for carbon allowances, helping companies to come up with different ideas…

Subaru has added; blindspot sensors, rearview cameras, new airbag technology, high-tech assisted driving features, and much more to compete with the expanding tech/auto universe. Globally we are seeing a rise in low emission cars, electric vehicles, and some prototypes of self driving vehicles. This rush of automotive technology creates a competitive market for car companies to keep up with. More hands off technology is becoming common is cheaper cars, setting a new…

toxic emissions and dust, as they have serious consequences to the well being of people and wildlife. - Recycling is an easy way to be sustainable and has an adverse effect on the environment when keeping in mind how much waste can be created in a…

Computed Tomography A CT scan is produced using plenty of x-ray images from lots of different angles using computerized axial tomography (cat). It produces cross-sectional images or slices of bones, tissues and the angio portion which is produced through a CTA (cat scan angio) allows professionals to view the blood vessels. It is a great medical tool, with interesting history and of course like everything else in the worldwide medicine, it has its pros and cons. A Computed Tomography scan is a…

The Physics of PET Scans All elements are composed of atoms, which are composed of small particles called protons, neutrons, and electrons. The nucleus of an atom is made of a tightly packed collection of protons and neutrons. You would think that with positively charged protons being packed so closely together the nucleus would fall apart, however this is not the case. There is an attractive force called the “nuclear force” which is able to overcome the repulsive force of the adjacent…

In as much as different forms of body scanning exists, positron emission tomography has been found to be very effective in the treatment and control of tumors and metastases. The technology uses radioactive tracers to check on the normal functioning of the body. Actually, this form of imaging has been found to be very effective in management and treatment of abnormal body functional processes. The scan does not use a lot of time and tends to be less risky as well as having limited side effects.…
