[Analysis of the management of hypertension complications in patients during emergency care].

Aim: To analyze the management of patients with associated complications from hypertension to improve prehospital therapeutic and diagnostic care.

Material And Methods: The accounts and records (125,905 calling cards over 2012-2014) of the Statistics Division, Karaganda Regional First Aid Station, were used. The methods of clinical and mathematical analysis were applied.

Elastic laser light scattering by GaAs surfaces.

Angle-resolved scattering (ARS) intensities were measured in the backscattering hemisphere for the (1 0 0) and (1 1 1) faces of GaAs single crystals. Three epitaxial layers were deposited onto the GaAs (1 0 0) single-crystalline wafers. The laser elastic light scattering shows the presence of a regular surface microrelief whose orientation corresponds to the crystallographic axes in the surface plane.

Atomic structure display of a real silicon surface under light scattering.

Angular dependencies of the scattered light intensity were measured on Si wafers that have different crystallographic orientations by using a He-Ne laser (λ = 632.8 nm, 80 µm spot diameter). During the experiment the Si wafer was fixed relative to the incident beam.
