His computer system at home was connected on a dedicated private line to a system at Bell Labs‚ and he often worked at home until three in the morning. Even in the early 1990s‚ after he became a manager at Bell Labs‚ his work habits did not change substantially. "It still tends to be sort of late‚ but not quite that late‚" Ritchie told Patrick Moore in an interview. "It depends on what meetings and so

Sixty-one years ago last November‚ John Bardeen and Walter Brattain discovered the transistor at Bell Labs‚ in 1951. Before this‚ electronics used tubes‚ which happened to be extremely bulky‚ generated lots of heat‚ and had short life spans. The invention of smaller‚ more efficient‚ and more durable transistors brought a revolution in electronics. They became an important discovery that changed the world forever. The first ideas and experimentation with solid-state electronics began in 1874‚ but

CHAPTER-1 INTRODUCTION 1 INTRODUCTION The organisation can be defined as “the planned coordination of the activities of a number of people for the achievement of some common‚ explicit purpose or goal‚ through division of labour and function and through a hierarchy of authority and responsibility.” Organisations are not just means used by groups of people to achieve some goals. They present different images like‚ Organisations as machines Organisations as living systems Organisations

single member of the group is not possible. In order to determine the cause of a disease the microbe must be separated from the mixture and cultured as a pure culture. The standard method of obtaining a pure culture is the streak-plate method on agar. The streak-plate method is an example of a solid dilution technique. Bacteria are obtained from a mixed culture with a sterile loop or wire and diluted within three sectors on a petri dish containing appropriate growth medium. After incubation

Abstract Introduction An antimicrobial is a substance that kills or inhibits the growth of microorganisms such as bacteria‚ fungi‚ or protozoans (Antimicrobial). Antimicrobial drugs either kill microbes or prevent the growth of microbes. Disinfectants are antimicrobial substances used on non-living objects or outside the body.

The very first day of the Unknown project I was acquainted with Denise who was very friendly and was very nice as far as assisting me in the project. The first day we were introduced too various different forms of the unknown such as broth‚ Blood agar plate‚ MSA plate‚ MAC plate‚ and the EMB plate. Before that we had done the 3 phase isolate which we had a possible of 10 points of achieving. In the isolation plate we had too take the sample of our unknown‚ which was the letter G. After we had

The Results from the Gram positive tests indicated that the unknown #4 was Streptococcus pyogenes. All seven tests on the unknown matched S. pyogenes perfectly. The blood agar plate proved the unknown to be β hemolytic‚ meaning the unknown bacteria was capable of complete hemolysis. This test separated the unknown into the β Streptococcus group‚ narrowing the possible bacteria to S. aureus or S. pyogenes. The Catalase test was used to determine if the unknown could break down hydrogen peroxide
