Electroencephalography (eeg) was divided into four parts from shallow to deep. Part 3 and 4 are characterized by an apparent low frequency brain wave, known to experts as slow-wave sleep. In the first three hours of the night, humans spend more time in slow-wave sleep than in the hour before they get up. Children are the easiest to get into slow-wave sleep, so they sleep well when they get them out of the car and into bed. On the other hand, adults have very little slow-wave sleep, perhaps because they get up a lot in the middle of the night.
But one time, scientists have suddenly clarified the direction of memory research. In the past few years, stikgaard and his colleague Matthew. Walker studied the effects of sleep on procedural memory of motor skills at the beth medical center in Boston, USA. They allowed the right-handed trainees to use the left hand over and over again as quickly as possible. They found that, regardless of the experiment was conducted in what time of day, the accuracy of the trainees will be increased by 60% to 70% after 6 minutes and if the trainees to accept the experiment in the morning, after 12 hours to test again, their accuracy and no big improvement. But when trainees are trained at night and are tested after getting up, their speed will increase by 15% to 20% and the accuracy will increase by 30% to 40%.
Men's 25 m pistol shooting distance of 25 meters a target with small rapid fire pistol shooting bullets, 60 in each group 5, according to 8 seconds, six seconds, four seconds shooting time sequence of the first two groups, a total of 30 bullets, and then by the same method for a second 30 bullets shoot, shoot away within the given time. The sum of the scores of the two groups is the total score, and the ranking is ranked according to the total score. (HPS) full score. The total score of the pistol event was 600.

Currently, African American communities live an extremely difficult life inside Cleveland City due to discrimination. Discrimination with this city is perpetrated in several forms. Occupational discrimination is incredibly prevalent the location where the African Americans are generally used in low paying jobs while the whites occupy well paying jobs. Racial discrimination within the United States of America, as indicated by Rummel (2003), is really strong which a white American cannot order products from an African American. Most of these racial discriminations are witnessed in cities in which the African Americans struggle greatly to secure a job. This has widened the gap between these two communities because victims remain poorer and poorer (Frazier & Tettey-Fio, 2006).
