The first theory is that blood donors must be considered “healthy” before they roll up their sleeve, so they are less likely to suffer heart disease because they are already in good health and probably have lower blood pressure and cholesterol levels that non-blood donors.
The second theory is that iron has a significant impact on atherosclerosis, or hardening of the arteries. When you give blood you are removing 225 to 250 milligrams of iron from your system, thus cutting your risk of heart disease.
Pre-menopausal women tend to have half of the amount of iron as men because they lose iron every month through menstruation. Coincidentally, they also suffer half as many heart attacks.
However, once a woman goes through menopause her risk of heart attack increases, but donating blood can reduce that risk.
In addition to depleting iron levels, when you donate blood we give you a free mini-physical and let you know your blood pressure as well as you cholesterol levels-two major risk factors when it comes to heart disease.
While scientists are researching why donating blood reduces the risk of heart attack, one thing is clear-donating blood has many benefits to the donor as well as the recipient. So, if you want to pick up a healthy habit, head over to your local blood center and give the gift of life.
Plus, when donors give blood they receive a cholesterol test and a mini-physical that can catch certain illnesses in the early stages. Florida’s Blood Centers tests blood from donors for numerous diseases including HIV 1 and 2, West Nile Virus, Syphilis, Hepatitis B, Hepatitis C, T. Cruzi or Chagas as well as the Human T-Cell Lymphotropic Virus 1 and 2.

As doctor’s have become more knowledgeable about the circulatory system and the blood that runs through it, the use of blood transfusions have steadily decreased.

A large infusion of red blood cells could increase blood thickness and cause a decrease in cardiac output and a reduction in oxygen content. Both would reduce aerobic capacity. The human heart was not designed to pump thickened blood throughout the body and, therefore, it could lead to a multitude of problems. Even more frightening is the list of diseases that can be contracted through homologous blood transfusion (It includes hepatitis, AIDS, malaria, and CMV.)

In October 1998, M&S’s began to face problems which they tried to overcome byadopting different strategies. However, their efforts proved to be unsuccessful and there areseveral factors attributed to that failure.Their products were old-fashioned and remained unchanged for many years. M&S’scompetitors sold products that were more design-focused and up-to-date. Small companies alsooffered similar clothes as M&S stores but at lower prices. Even though M&S was a very wellknown company, they no longer understood or reacted to its customers’ changing wants andneeds. Therefore, they did not understand their target market, who might want different varietiesof products. They expanded their business but continued with its traditional design and ignoredthe changes in the market place.To overcome their problems they focused on the day-to-day operations of the firm.However, plans were not worked out on a long-term basis. There was internal managementresponsible for this. The company mostly made women’s wear, but top levels were dominated bymale executives, so they did not realize the women’s preferences and design choices. Therefore,they did not implement the right strategy for the market. The company also always promotedtheir CEO or Chairman from within the company and thus they did not have any fresh outlooksor suggestions for the business. The decisions that were made did not fulfill their expectations.All of these are some reasons behind the fail to overcome the problems during 1998 to 2001.Early in 2000, they make the decision to appoint Luc Vandevelde as new Chairman of M&S.…

GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually, the process is as much a cutting action as drilling, milling, and lathe turning.…
