A respiratory rate, or breathing rate, is the number of breaths a person takes in one minute while at rest, and it can be measured by counting the number of times a person's chest rises and falls within one minute.he opposite of apnea is tachypnea, or rapid breathing. A faster than normal respiratory rate may be caused by the flu or a cold in children, and pneumonia and asthma may also cause an increase in the rate of respiration in people of all ages.
In the social sciences, the most prominent manifestation of realism is. the âcritical realistâ tradition usually associated with the work of Roy Bhaskar. (1978, 1989, 2011; Archer, Bhaskar, Collier, Lawson, & Norrie, 1998; Manicas, 2006; Sayer, 1992, 2000).
Historical Background. It is considered by some that the screw thread was invented in about 400BC by Archytas of Tarentum (428 BC - 350 BC). Archytas is sometimes called the founder of mechanics and was a contemporary of Plato. One of the first applications of the screw principle was in presses for the extraction of oils from olives and juice from grapes. The oil presses in Pomeii were worked by the screw principle. Archimedes (287 BC - 212 BC) developed the screw principle and used it to construct devices to raise water.
