The young people who have approved during the last weeks the Selectivity must choose race. And they are going to find a little more difficult to enter which want, because the competition greater must essentially to the increase of the pupils with a small reduction of the supply. If in course 2009-2010 it were possible to be acceded approximately with 5 of average note to 60% of the races that offered the campuses actual public, in this course 2010-2011 that is on the verge of finishing the approved one just gave access to little more of 42%, that is to say, to a little more 890 degrees (counting each race in each faculty). If we relaxed a little the criterion and we put in that coat the races that are in the 5 and the 5.1, the number grows up to 940 titles, 45%. In the opposed side, in more than 130 titles it was necessary to remove more from 10 to enter. Source of the news: : To choose race, more difficult by the Selectivity and the ascent of students
This is obtained with the exercise known like confused, the consisting of one breathing only through the tuba, without having the glasses protecting the nose. In this way and, although at the outset something disagreeable can be, obtains a blockade total of the nasal routes, not breathing by them and, therefore, not inhaling water. Another absolutely fundamental exercise in any course, is the casting of glasses, the great problem (never insurmountable) of many students. The mask whatever its design, counts on an air chamber between our eyes and the crystal. It is this trick of the vision under the water, the difference to be on the awares simply. It is therefore fundamental to maintain this small water space free. Lamentably it is not always possible, are many the times in which by different reasons the glasses fill of water (badly it fits, a flap, an abrupt plunge, hairs or moustaches, etc.) and is high-priority his casting.
The technique is simple and perhaps most important it is the tranquillity at the time of realising it. It consists simply of expelling air by the nose, at the same time as smoothly we moved slightly the glasses of the face. The air under pressure will be moving the water. It is an exercise that agrees to repeat until the perfection is reached, because it is a situation of most normal. At the outset it costs, being able to sometimes get to lead to the panic. For that reason it agrees to dominate it totally. At past times it was normal between the instructors in the examination, to give manotazo to the glasses of the student and to take off them under the water to observe its reaction. Today luckyly these practices usually are not realised, trusting more the capacity and gradual improvement of the nascent one. Dominated the aquatic element already one goes to the phase that in truth people hope.
Hipotlamo, part of diencfalo, with inferior localization to the thalamus. He is composed for about twelve nuclei, forming four main regions. To mamilar, posterior part of hipotlamo includes the bodies mamilares and the posterior hipotalmico nucleus. The tuberal region, that is the part widest of hipotlamo, includes the nuclei back-medial, ventro-medial and hooped, more infundbulo. The medium eminence, slightly prominent region, that surrounds infundbulo. The region supply-optics is superior to quiasmo optic, nucleus to paraventricular, the supply-optic nucleus, previous the hipotalmico nucleus and the supraquiasmtico nucleus.
The region daily pay-optics, is previous the supply-optics is, generally considered as part of hipotlamo, for participating it together with, of the regulation of certain autonmicas activities. Hipotlamo is one of the main regulators of the homeostasia. Other receivers, in proper hipotlamo, continuously monitor the osmtica pressure, certain hormonais contractions and the temperature of the blood. The main functions of hipotlamo are the following ones: Control of the SNA: hipotlamo controls and integrates the activities of the autonmico nervous system, that in turn, regulates the contraction of muscles smooth cardiopath of the secretion of many glands. By means of the SNA, hipotlamo and the main regulator of the visceral activities, including the regulation of the cardiac frequency, the food movement throughout the gastrintestinal treatment and of the contraction of the urinria bladder.
Control of the gland hipfise: hipotlamo produces some hormones and has two types of important connections with the gland hipfise, a endcrina gland, with inferior situation to hipotlamo. Regulating hipotalmicos hormones are set free in hair nets, in the medium eminence. The cellular bodies of these neurons produce one of two hormones (ocitocina or antidiurtico hormone). Regulation of the emotional and mannering standards. Together with the lmbico system, hipotlamo regulates the feelings of anger, aggression, pain and pleasure, also, behavior related with sexual activation. Regulation of the water and food ingestion.
