How destroys the blast?

The shock wave is a rapid rise in atmospheric pressure caused by the release of energy that takes place at the sudden transformation from solid to a gas explosion.

To penetrate the body, the shock wave subjected to corporal viscera to a high overpressure and a violent displacement.

This causes the rupture of the surface of dense materials, such as gastrointestinal or the alveolar wall.
In addition to the damage in such areas, the water glasses that these organs burst, causing severe internal bleeding.

Moreover, the passage of the wave causes the tissues to move at different speeds depending on their density, causing severe damage to them.

The anomaly of water: ice

Unlike the vast majority of substances, ice floats in water liquids. That's because this is no more dense when you're at 0 ° C, but at 4 ° C. If not, there would be no icebergs or resale pipes to get frost. In addition, rivers and lakes begin to freeze the fund to the surface-and we could not skate on them.

It is not the only peculiarity of ice. In fact, there are 14 different varieties, something equally special because solids usually show two or three different types of crystalline structures.

The fact that we all know has a hexagonal structure and is called Ice Ih, but playing with the pressure and temperature can generate other structures.
In nature we also find ice or cubic lc, which is formed from water vapor at normal atmospheric pressure, but at temperatures below 80 ° C below zero. This kind of ice may form in the upper atmosphere.

In 1900, physicist Gus-tav Tammann discovered that the ice if subjected to 3,500 atmospheres-three and a half times the pressure that exists at the bottom of the Mariana Trench-appeared two new states: ice II and III.
A decade later, Percy Bridgman, from Harvard University, identified 5 more varieties. Among them, ice VI was known as "hot ice" since remained without melted to 80 C, provided that they exercise over the 6,500 atmospheres.

Of these, the most ghostly is the ice IV, whose structure was not discovered until 1981, 44 years after being detected, because it becomes very quickly into a more stable, V. And the race continues in 2006, Science magazine reported obtaining ice XIV.

In the solitude of the only space we have found that ice is amorphous. How do you get it? Well, ice cream artisans hold the key: cool very quickly to prevent crystals from forming.

Evita pains in front of the PC

The causes are the fact of bending with force the doll toward before, behind I heard to the side, for tipear long lapses of times without resting, especially with the arched doll or flexionada. To solve ésto, mantén the right and lifted dolls of the keypad, you stretch the fingers pushing them back with the other hand or separating them.

How to remove the pressure

They exist exercises that increase the energy of the body, advantage that are useless if continually we waste that vitality when conserving the prepared muscles to use a lot of force, when you are not any necessity so that you are this way.

We offer you a series of very plain exercises so that you practice them where and when you can that will help you, to remove your pressure in an immediate way, and you will be able to this way to continue the daily activity.

Infantile nightmares

Regarding the infantile fear, this is relatively easy of reducing: coarse with redear to the boy of an environment in the one that feel safe and understood.

The specific phobias are habitual in the childhood; I eat for example to the dogs or winches, darkness, among other; although the correct thing is that the boy, as you grow you acquire the necessary surety to reject those irrational fears and you find other channels to come undone of your pressures. If the fears last after the first adolescence, the problem has been set up.

In general, the phobia doesn't usually have an explanation racinal. The same one phobic, you argue that you are about bare "foolishness", but the certain thing is that it cannot be controlled optional or it can derive others. So, near 60% of those who suffer social phobia, end also suffering other phobias, depression and wonderful disorders. You are communio to hear in the queries, so fatidical reflexines as for ejemlo this: "Not I can accept an invitation, I cannot leave my house."

You are very effective for psoriasis, mushrooms, acne and burns of different classes. Your gel acts as a regenerator of the skin.

Arterial Hypertension

Hypertension means an elevation of the arterial pressure above the normal borders. This already outlines a first problem: to define these borders. The arterial pressure varies with the age, and in oneself individual can oscillate in any moment due to multiple phenomena: emotion, cold, physical activity, etc. A border wild maximum of 145 mm of mercury usually accepts (Hg.) for the systolic pressure and of 90 mm of Hg. for the diastolic pressure under idle conditions.

Diverse apparatuses exist, named esfigmomanómetros, for the determination of the arterial pressure. They consist on a bag rubber and cloth and in armlet form that is arranged around the arm or leg. This bag is wired to a gauge that measures the variances of the pressure of the interior of that. When the pressure inside the bag overcomes to the pressure inside the artery, the step of blood is discontinued by the same one and the pulse disappears beyond the point of application of the pipe nipple. By means of the observation of the keystrokes or the auscultation with a stethoscope, the moment can be determined in that passes blood again as it is made descend the pressure inside the pipe nipple. The figure of pressure at this time corresponds to the systolic pressure or maxim. The diastolic pressure or minimum it is recognized by auscultation and it corresponds to the moment in that he/she stops to be auscultated the pulse to be made the continuing flow. The arterial pressure is expressed in a mm of mercury.

From the etiologic point of view, that is to say, as for the lawsuit of the elevation of the arterial pressure, they are distinguished do groups: the main or primary hypertension, of unknown lawsuit, and the secondary hypertension to diverse illnesses.

The arterial hypertension is a discovery they frequent the clinic. The frequency of this affection increases with the age, near 80 percent of the hipertensos it is between the 40 and 70 years. Until the 40 years, the man has bigger trend that the woman to be affection of hypertension; above the 40, the status is invested. Of the 80 to 85 percent of all the cases, the hypertension can be considered as main. In this an illness that seems to be related with the progress of the civilization, being strange in the asiatic and African countries. But it is not related with he/she prays her, since among the blacks of United States of North America it is more frequent than among the white population.
