After a careful study on the area map between points the way forward movement must identify yourself in the path is well recognizable, often located on the ground reference points, to draw a map elected route movement, and measuring the true azimuth protractor all sections of track between features translate these into magnetic bearings, and then on the map to determine the length of each segment and recalculate the distance obtained in their steps.
Preparing the route charted the movement and writing angles and distances leave from the start point.
Citing the motion compass needle, guided Read more [...]
All biological processes in the human body, are subject to the rhythm.
As a young athlete should organize their time to make our plans? First of all you need to accustom themselves to the correct mode of the day, is a reasonable alternate different activities and recreation.
Tables 1 and 2, you can find an example, you are comfortable with the daily routine.
Table 3 shows the number of hours the average duration of activities and recreation in school during the day (according to Belov). Schedule be appropriate so that a lesson with eyestrain performed gymnastic or music classes. This combination Read more [...]
As can be seen from the above, in boxers, long involved in this sport, there are often morphological and functional disorders of the central nervous system, and was a positive correlation between the amount spent boxer fights, the duration of its career and the development of neurological, psychiatric symptoms and histopathological «punch drunk "syndrome.
No less dangerous long-term effects of repeated trauma to the brain, the cumulative effect of blows to the head, that is, the accumulation of the effects of systematic slack head blows that boxers are in training, especially in competition. Read more [...]
Operation "Resection of cartilage cover" is made under anesthesia. Incision of the skin and fascia often internal, parapatelyarny. Has audited the joint. Cartilage lesion is excised with a sharp knife to healthy tissue, exfoliation plate cartilage are removed completely. Ulcers excised "saped" edge, so as to make (their more flat (it is known that "saped" ulcer edges crumble, as the main source of free hondromnyh body that irritate the synovium and cause synovitis.) To stimulate regenerative processes fine needle to make multiple tunneling and bottom edges of the Read more [...]
Fig. 1. Roentgenokymography: I - odnoschelevaya; II - multislit. 1 - patient 2 - direction of the rays, and 3 - Tape 4 - odnoschelevaya lead grids, 4a - multislit lead grids, 5 - direction of the magazine, 6 - direction of the lattice.
Roentgenokymography - X-ray method for studying the movement of internal organs, exercised through graphic recording fluctuations in their paths by roentgenokymograph. Roentgenokymograph principle (Fig. 1) consists in the fact that between the test body and the X-ray cassette is placed lead grids having one narrow gap (Odnoschelevaya roentgenokymography) or more Read more [...]
A closer analysis of tracking data revealed that continued tracking is not really a consequence of inability to stop motion head and eyes. Frame by frame analysis of the video recorder records showed that all children - even the youngest (12 weeks) - was stopped at a stop tracking the subject, and then, after an interval of a few hundred milliseconds, the eye movements resumed the path of following the subject until it stops. In other words, babies are able to stop the movement of the head, but then again they began to "follow", ignoring the apparent stationary object.
There are several Read more [...]
The essence of the movement by the azimuth is the ability to withstand with a compass direction, and just go for the scheduled item. This method is indispensable for driving on unfamiliar terrain in the mountains, in the woods, in the desert, especially at night and in other low visibility conditions. Especially need these skills in combat troops. Azimuth go to explore and come back from it, is held direction offensive attack to march troops to various locations.
How then prepares the data for the movement in azimuth and what they represent? Training on a data card for traveling on the Read more [...]
3. Important for successful auditory localization of objects in adults have head movement. If head listener at rest, then the same set of symptoms proximal position - phase, timing and intensity of binaural differences - corresponds to a set of possible directions for source sound, geometric form the surface of a cone whose axis is passing through the left and right ear line (Velichkovsky, Zinchenko and Luria, 1973). Specifying the spatial localization of the sound source movement of the head can be very small, not reaching in magnitude to the angle sounding object. Since the neck muscles are Read more [...]
According to this theory, the perception of the situation and its constant depends on the combination of two independent sources of information - information on the location of retinal stimulation and information on the situation of the eye. Most authors who have written on the subject, taking information about the location of retinal stimulation given, considering it something that does not require further explanation. The theme that really excited the researchers XIX century, was the nature of our source of information on the eyes. There were two conflicting hypotheses. In one of them saying Read more [...]
At one time it was thought that the cause of avtokineticheskogo effects are subtle eye movement. According to this hypothesis, the eyes move without registering efferent signal, and there are changes in retinal stimulation are interpreted as the result of the motion of the object. Notice how this hypothesis weakens the theory of efferent copy. If the system can make mistakes in assessing the movement of 40 °, the theory explains how the perceptions of the situation and constancy under normal conditions, when the spatial localization accuracy is better than 1 °? In any case, and this hypothesis Read more [...]
In the next phase of the experiment examined responses to infant motion air and visual changes separately. The displacement of the air will rise to express the answers that would have been quite different from responses caused by the approaching object. One only motion air causes very rapid closing of the eyes, followed by a slow rotation motion head, or tilt of the head or raising of hands was not. Thus, the movement of air alone can not be responsible for the protective reaction of the infant, resulting in answer the approach of the subject. After this we would consider responses to visual Read more [...]

Paralysis, paresis - no voluntary movement (paralysis) or weakening movements (paresis), Which develops as a result of the defeat of the motor centers and pathways of the central or peripheral nervous system. Paralysis and paresis should be distinguished from movement disorders caused by disease of other parts of the body: bones, joints, and limitation of movement due to pain, inflammation and traumatic diseases of the muscles and joints. Causes paralysis and paresis may be infectious, degenerative, traumatic nervous system diseases and tumors. Sometimes the paralysis observed in the second Read more [...]
Particularize, what kind of insurance is in error in this case. Simultaneous movement of ligaments in the mountainous terrain - a common and well-founded view of the movement. The relief should be such that in case of failure of both athletes and had been able to use an ice pick or brow to samozaderzhaniya and rope for mutual insurance, that is, along with the objective characteristic of the terrain is taken into account and a sports qualification climbers.
Quick, skillful actions athletes can reduce slippage along the slope and thus reduce the number of injuries and possible injury, do not Read more [...]
The hippie movement started quite innocently. Initially, on street corners and in parks to gather in small groups of boys and girls, dressed in typical style, that the sounds of guitars or transistors sit and smoke hashish. In this case, they appear to people peacefully inclined and quite interested in the events going on around them. Get in contact with passers-by, they are polite and willing to talk. Prudent and reasonable they set out their views on the topic of love, peace, and sexual freedom.
Their emotional statements against the war in Vietnam, as well as against any other war. However, Read more [...]
