Ion drives

Ion drives are the most cost-effective propulsion systems currently available and can send deep space probes faster and further than any other type of rocket technology.

Unlike conventional chemical rockets that burn at a fast rate over a short period of time to generate huge thrust, ion drives run at a steady rate over a long period to generate a high velocity.

The ions travel at 31.5 kilometres per second (19.6 miles per second) and produce 0.5 Newtons (0.1 pounds) of thrust. This force is equivalent to the weight of a few coins dropped into your hand, whereas chemical rockets

Computed tomography

Industrial X-ray computed tomography emerged as a reflection of the fabulous success of medical computer tomography, invented by British engineer GN Hounsfield, who published the first description of a computer tomograph in 1972 [1].

Since then, the dignity of the medical tomographic diagnosis is not outdated, and it continues to help people to be treated in thousands of hospitals around the world. The unprecedented scale of the success of the medical X-ray tomography — a consequence of the happy coincidence

Vascular anomalies of the nervous system — one of the most common causes of stroke in young children. Establishing the causes of stroke in adolescents and children causing considerable difficulties, and therefore cerebral strokes in childhood of 20-30% of the cases take place under a variety of misdiagnosis. Contradictory information on the incidence of stroke. There is no complete picture of the nature, frequency of recurrence and outcome of stroke in different age groups. The incidence of stroke in children, according to the literature, and generally different amounts to 2-7 per 100 000 per year. Especially severe hemorrhagic strokes in young children: during breast feeding in an apparently perfectly healthy baby suddenly appear general tonic convulsions with loss of consciousness, episodes of apnea, repeated vomiting, further increases in intracranial hypertension clinic.

Visually determined bulging fontanelle, and a large voltage to the divergence of the cranial sutures and the absence of pulsations, the severity of subcutaneous vascular pattern on the head.
