Chapter-06 Lipids by Sharma Suresh K (2014) Edition : 1/e

Chapter answers the functions of lipids, their classification and role of liver in fat metabolism. It also discusses the biological importance of important lipids and their functions. Fat (lipids) are organic substances insoluble in water and soluble in organic solvents such as ether, alcohol, acetone, etc. These are made-up of fatty acids. Lipids- include f... [More]

Chapter-06 X-ray Production by Thayalan Kuppusamy (2017) Edition : 2/e

X-rays were discovered by WC Roentgen, the German physicist in 1895, when he was investigating the conduction of electricity through gases at low pressure in glass tubes. X-rays are produced when fast moving electrons are stopped by means of a target material. The moving electron possesses kinetic energy equal to ½ mn2, if m and v are the mass and velocity o...

Chapter-07 X-ray Tube Technology by Thayalan Kuppusamy (2017) Edition : 2/e

This chapter basically talks about the X-ray tube technology. In earlier periods, gas tubes were used to produce X-rays. But these tubes had lot of disadvantages. Hence, Coolidge proposed a prototype X-ray tube based on the thermionic emission principle. On the basis of Coolidge tube, several X-ray tubes have been designed. The stationary anode X-ray tube is... [More]

   Chapter DOI:10.5005/jp/books/11603_7      

Wilhelm Roentgen’s reported X-rays in 1890. Today, imaging with X-rays is perhaps the most commonly used diagnostic tool with medical profession. X-ray unit is in fact a life line of any working hospital. This chapter carries information on x-rays tube and its maintenance and working of x-ray machine with electric circuit. Further, mechanism of X-rays produc... [More]
