Whirlpool of the Arabian Sea

One of the strangest ocean currents - swirling clockwise great vortex that occurs each summer off the coast of Somalia and the sea surface temperature changes, affecting the monsoon, carrying life-giving water to Asia.A hundred years the sailors know that the Great vortex occurs simultaneously with the monsoon season in early June and disappears in September - about a month after the winds subside.

Fire and burning. The idea of fire and combustion

Fire - Uncontrolled burning, causing property damage, damage to life and health of citizens and the interests of society and the state. Goren called fast flowing chemical oxidation or compounds of combustible material and oxygen is accompanied by the release of gas, heat and light. Known burning and without oxygen to give heat and light. Therefore, combustion is a chemical reaction not only connections, but the expansion. With the highest rate of combustion occurs in pure oxygen. With a decrease in oxygen concentration burning slowing. The lowest rate of combustion is achieved when the content Read more [...]

Inhibition

Braking - a physiological process in the central nervous system, resulting in a delay of excitation. Inhibition can not be spread like excitations (see), as local process. Inhibition occurs at the time of the meeting of two impulses, one of which is inhibitory and the other inhibited. Braking process was first shown in 1862, Russian physiologist IM Sechenov. Incision was made in the frog brain at the level of thalamus with the removal of the cerebral hemispheres. Measured the time reflex flick hindpaw immersed it in a solution of sulfuric acid (method of Turks.) When applied to the thalamus Read more [...]

Circulatory failure in athletes

Circulatory failure - a condition in which the normal function of the cardiovascular system can not provide the required level of blood supply to the body.

Testicular pathology

Atrophy testis may be due to physiological bilateral age, malnutrition, radiation damage, etc. The eggs are reduced, their soft texture, the function is suppressed or absent. In some cases, may restore function after treatment. Often after severe inflammation in the testicles develop unilateral atrophy with abundant development of scar tissue, reducing the number of tubules and their lumen, small testes size, dense texture, sometimes with scar retractions albuginea. Hypertrophy testis occurs due to the removal of one testicle and is in the nature of compensatory. Testis can be greatly increased, Read more [...]

Pericardium-1

Morbid anatomy. Abnormalities. Complete or partial absence of the parietal pericardium sheet is rare. When the sternum cracks found a defect in the anterior wall of the pericardium, sometimes accompanied by ectopic heart. Developmental disorders kyuverova flow can break the side wall of pericardium (usually the left), with the result that there is communication between the cavity and the cavity P. pleura. A defect in the lower part of the pericardium is sometimes observed simultaneously with a defect in the diaphragm, which can be accompanied by the introduction of a cavity AP abdomen with Read more [...]
