Devices and Designs: Medical Technologies in Historical Perspective

During this quantity, best students within the historical past and sociology of drugs concentration their cognizance at the fabric cultures of well-being care. They examine how know-how has turn into so significant to drugs over the past centuries and the way we're dealing with the implications.

Tissue Engineering for the Heart: A Case Study Based Approach

This e-book covers the basics of tissue engineering for the guts, beginning with the fundamentals of organ iteration, sensors in tissue and organ fabrication, and the present state of the art in stem telephone engineering for the guts. With this beginning in position, the remainder chapters specialise in particular points of the cardiovascular process, beginning with middle muscle, then organic pumps, by way of bioartificial ventricles, and at last, bioartificial hearts.

One very important radionuclide arises mainly from the interaction of neutrons in cosmic radiation with nitrogen in the upper atmosphere to form carbon-14 as follows: 14 N (n, p)14C Naturally occurring radioactive material (NORM) Carbon-14, which has a half-life of 5568 years, diffuses to the lower atmosphere, where it may become incorporated in living matter. 1 ¥ 105 years) are maintained in the lower atmosphere by cosmic ray reactions. They are much less important than 14C. Some of these radioisotopes, particularly 14C, can be absorbed by plant life and subsequently cycled into the whole food chain.

As a result, there are programmes in a number of countries to identify dwellings and workplaces that have high concentrations and, where necessary, to undertake remedial work. Radon can be ‘actively’ measured using specialized ionization chambers which continuously measure and record the amount of radon or its decay products in the air. However, such equipment is expensive and requires expert operation. As radon concentration inside buildings can vary significantly with time, depending on area usage and weather conditions, prolonged measurements using ‘passive’ radon meters often provide a more reliable and much simpler approach.

It remains at about this figure until much higher doses are reached. In this region, the radiation dose causes severe depletion of the cells lining the intestine. Gross damage occurs in the lining of the intestine, followed by severe bacterial invasion. This is called the region of gastrointestinal death. At much higher doses, survival times become progressively shorter. There are very few human data in this region, but from animal experiments the symptoms indicate some damage to the central nervous system and hence the region is called the region of central nervous system death.
