Answer:
Infections are caused by microscopic organisms known as pathogens—bacteria, viruses, fungi, or parasites—that enter the body, multiply, and interfere with normal functions. Infectious diseases are a leading cause of illness and death in the United States and around the world. For certain people--particularly those with underlying illnesses like heart disease or cancer, those who have serious injuries, or those who are taking medications that weaken the immune system—it's more difficult to avoid getting sick with an infection. Living in an affluent country like the United States, the threat we face from deadly viruses, bacteria, and parasites can seem remote, but these infectious microbes are ever present among us, according to Dr. Michael Klompas, writing in the Harvard Medical School Special Health Report Viruses and Disease. Dr. Klompas is an infectious disease specialist at Harvard-affiliated Brigham and Women's Hospital. However, for most healthy people, following a few basic principles can go a long way in helping to prevent infections.
Answer:
Actually, Fe-0.17% C steel is a peritectic steel because only this steel undergoes above reaction completely. When cooled from molten state, this steel starts solidifying at point x and the first solid going to nucleate is of δ-ferrite. As cooling continues more of δ-ferrite solidifies [Fig. 1.23 (b)] and at any temperature, say T1, Lever rule helps to calculate the fraction of δ- ferrite (= FG/EG) and the liquid (= EF/EG).
