Metal-Semiconductor AsSb-AlGaAsSb Metamaterial.

AlGaAsSb and AlGaAs films as thick as 1 μm with Al content as high as 60% were successfully grown by low-temperature (200 °C) MBE. To overcome the well-known problem of growth disruption due to a high aluminum content and a low growth temperature, we applied intermittent growth with the temperature elevation to smooth out the emerging roughness of the growth front. Post-growth annealing of the obtained material allowed us to form a developed system of As or AsSb nanoinclusions, which occupy 0.

Structural transformations in the low-temperature grown GaAs with superlattices of Sb and P δ-layers.

The structure of low-temperature grown GaAs with equidistant δ-layers of Sb and P was studied by analysis of the X-ray curves, which was supported by optical absorption measurements and transmission electron microscopy. The simultaneous fitting of the X-ray reflectivity curve and diffraction ones for GaAs (004) and GaAs (115) crystallographic planes provided reliable information about the period of δ-layer superlattice, thickness of the Sb and P δ-layers, and amount of excess As. Variation of these parameters was documented when excess As precipitated into As nanoinclusions upon annealing.

[Antioxidant effects of vetoron in flying personnel with arterial hypertension].

The purpose of the investigation was to assess the possibility to control free radical oxidation in patients with cardiovascular pathologies with the help of vetoron. This was the first attempt to study effects of a beta-carotene (vetoron) on lipid peroxidation and the activity of antioxidant defense enzymes in flying personnel with cardiovascular pathologies (hypertension and neurocirculatory dystonia). Therapeutic effect of the medicament was evaluated by its action on peroxide metabolism (malonic dialdehyde, acyl hydroperoxides and trien conjugates, Schiff bases) and stimulation of the antioxidant defense enzymes (catalase and glutathione reductase).

Methodological aspects of the medical examination of special contingents in the All-Russian Service of Disaster Medicine.

The tasks required for the preservation of the health of rescuers can be accomplished with the creation of a system for medical examinations and rehabilitation that functions with commonly used methodological and organizational principles. Absence of such a common methodological platform often results in the disqualification of members of the special contingent and a mistake in the evaluation process that gives birth to serious medical and social problems. The specific character of the rescuers' activities during conditions associated with extraordinary situations necessitates the development of criteria-based evaluation systems for determining the prognosis, and the clinical, diagnostic, normative, and legal, medical, and social criteria that include methodological approaches that define the criteria to be used in the examinations.
