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

include a diverse group of plant foods that differ greatly in their energy and nutrients content‚ and form an important component of the human diet. They are excellent sources of nutrients‚ specifically essential vitamins‚ minerals‚ fiber and complex carbohydrate and also add variety to the diet all of which are needed to support a healthy body and mind (Slavin and Lloyd 2012). According to the World Health Report (2002)‚ low fruits and vegetable intake is estimated to cause about 31% of ischemic heart

Amid high food prices in 1972‚ Sweden’s National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious‚ and "supplemental foods" that added nutrition missing from the basic foods. Anna Britt Agnsäter‚ head of the test kitchen at KF‚ a consumer co-op that worked with the Board‚ held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea

P5. Explaining the Concept of Homeostasis. M2. Probable homeostatic response’s to changes in the internal environment during exercise. The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is necessary because human cells are efficient but very demanding. The phrase homeostasis is a bit confusing; conditions inside our bodies are not constant but are kept within a narrow

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

How Sugar Affects the Body in Motion By GRETCHEN REYNOLDS Gary John Norman/Getty Images Sugar is getting a bad reputation. A cover article in The New York Times Magazine several weeks ago persuasively reported that our national overindulgence in fructose and other sugars is driving the epidemics of obesity‚ diabetes and other illnesses. But that much-discussed article‚ by the writer Gary Taubes‚ focused on how sugars like fructose affect the body in general. It had little opportunity to examine

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

In fact‚ they are “almost polar opposites of each other”(4). The Mediterranean diet consists of fruits and vegetables‚ good oils and chicken and fish (4). The American diet however‚ is high in carbohydrates‚ sugars‚ bad oils‚ and red meats (4). Unlike the Mediterranean diet‚ the standard American diet does not put an emphasis on fruits and vegetables (4).
