The PET scan‚ or Positron Emission Tomography‚ was born in 1973 at Washington University. It was created by Edward Hoffman‚ Michael M. Ter-Pogossian‚ and Michael E. Phelps; Phelps is most often credited with the invention (History of PET and MRI‚ 2009). In preparation for a PET scan‚ radioactive tracers are injected into the body‚ inhaled‚ or ingested by the patient through a solution that they drink. Then the scan will actually begin‚ as the patient lies on a table‚ which glides into the machine

Lawford Electric Company – Case Analysis Critical Summary This sale was Lawford’s to lose. Lawford Electric Company’s ongoing‚ 8-year relationship with Bayfield Milling Company‚ coupled with the geographic proximity of the two businesses‚ gave them a competitive advantage upon which they were unable to capitalize. The price tag of the drive system for which Lawford prepared a competitive bid represented more than 17 years of Bayfield’s average annual purchases from Lawford.¹ Sales engineer

Advantages and Disadvantages of Electric Vehicles Almost all households in this world uses a gas powered vehicles which causes the greenhouse effect or more known as the global warming. The global warming itself is caused by the emission of the gas powered vehicles. To prevent this‚ technologists have invented a vehicle that uses electricity. Although there are many benefits‚ in a developing countries‚ owning and using an electric car results in having both advantages and also disadvantages.

27/07/2014 Re: DEREGULATION GENERAL PURPOSE FINANCIAL STATEMENTS AND ROLE OF EXTERNAL AUDIT. The nature of accounting is changing with specific demands in the market. Today‚ the SME clients require specific information and thus there have been a positivist-accounting approach while preparing accounting statements. One step in this positivist approach is where the general purpose financial statements are becoming deregulated and let market forces control the quality of the general purpose financial statement

first applications of electricity was the first incandescent light bulb in around 1870. The electric overhaul of society obviously brought many fresh new dangers with it‚ but it eliminated some of the old ones‚ like the naked flames of gas lighting that was commonly used in homes and factories then. The Joule heating effect that can be found in light bulbs is also present in electric heating. Electric heating has been thought of as wasteful in the past because in order to create that heat energy

The Electric Car has a history but is there a future in the UK or will there be a better option? The invention of the first Electric Car was in 1830 but was not perfected until the creation of rechargeable batteries in 1859. By 1912 50 companies were producing 34‚000 electric cars. Once the development of the electric starting motor occurred and the price of fuel was cheap then the electric cars industry vanished. The oil crisis in the 1970’s caused some re-emergence of electric cars but the

I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal

pushed away‚ or repelled‚ each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel
