Technology has affected society and its surroundings in a number of ways

Technology has helped to develop many nations in much way that can't be explained.
Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment.

The use of the term technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, and usually referred to the description or study of the useful arts.

"Technology." By the 1930s, "technology" referred not to the study of the industrial arts, but to the industrial arts themselves. "Technology includes all tools, machines, utensils, weapons, instruments, housing, clothing, communicating and transporting devices and the skills by which we produce and use them.

The use of tools by early humans was partly a process of discovery, partly of evolution technology.
The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind

GIVE BLOOD GIVE LIFE....


BLOOD DONATION

 Do you know which man made the discovery of blood group ABO?
Landsteiner discovered the ABO Blood Group system in 1901, which is one of the most important landmark discoveries in the Transfusion Medicine

Now day's science has gone so far that can't be explain with the help of science we have made many thing but still now, scientist can't make blood. That's why we say BLOOD is so important. 
One can almost say that blood is that magic potion which gives life to another person. Though we have made tremendous discoveries and inventions in Science we are not yet able to make the magic potion called Blood.

Make donating blood with regularity a part of your life. The process is simple and safe. Minority groups have something special to give. Different groups of people have different percentages of blood types. Thus, it is important that every ethnic group participate in blood donation programs. Remember: you can save the life of a friend, a neighbor, and also a family member.


 THINGS THAT SHOULD BE IN MIND WHILE                            DONATING BLOOD……

Donor should be between 18-55 years of age with a weight of 50 kg or above with pulse rate, body temperature and blood pressure should be normal.

Our body has 5.5 ltr of blood of which only 350 ml - 450 ml of blood is taken depending upon weight of donor. Majority of healthy adults can tolerate withdrawal of one unit of blood. The withdrawn blood volume is restored within 24 hours and the hemoglobin and cell components are restored in 2 months. Therefore it is safe to donate blood every three months.People who are injected with the diseases they can't give BLOOD donation. If by chance they give blood donation thats not a give problem because donated blood undergoes various tests like blood grouping antibody detection, testing of infections like hepatitis, AIDS, Malaria, syphilis and before it reaches the recipient it undergoes compatibility testing with the recipient blood.
