Peculiarities of leadership qualities manifestation by modern managers of police organizations: psychological aspect.

Objective: Aim: To study the psychological peculiarities of the manifestation of leadership qualities by modern managers of police organizations..

Patients And Methods: Materials and Methods: The research conducted in 2022-2024 involved 64 mid-level managers of police organizations and 462 officers from police units directly subordinated to these managers.

Charged Amino Acid Substitutions Affect Conformation of Neuroglobin and Cytochrome Heme Groups.

Neuroglobin (Ngb) is a cytosolic heme protein that plays an important role in protecting cells from apoptosis through interaction with oxidized cytochrome (Cyt ) released from mitochondria. The interaction of reduced Ngb and oxidized Cyt is accompanied by electron transfer between them and the reduction in Cyt . Despite the growing number of studies on Ngb, the mechanism of interaction between Ngb and Cyt is still unclear.

Strain Hardening of Polypropylene Microfiber Reinforced Composite Based on Alkali-Activated Slag Matrix.

A comparative study of the fracture features, strength and deformation properties of pseudo strain-hardening composites based on alkali-activated slag and Portland cement matrices with polypropylene microfiber was carried out. Correlations between their compositions and characteristics of stress-strain diagrams under tension in bending with an additional determination of acoustic emission parameters were determined. An average strength alkali-activated slag matrix with compressive strength of 40 MPa and a high-strength Portland cement matrix with compressive strength of 70 MPa were used.

Supersulfated Cement Applied to Produce Lightweight Concrete.

The physical and mechanical characteristics of expanded-clay lightweight concrete based on a supersulfated binder in comparison with lightweight concrete based on ordinary Portland cement were studied. In replacing CEM 32.5 with a supersulfated binder of 6000 cm/g specific surface, one can increase the tensile strength in bending up to 20% and can increase the ratio of the tensile strength in bending to the compressive strength that indicates the crack resistance increase of concrete.

Association of polymorphic markers of genes , and with type 2 diabetes mellitus in the Russian population.

Background: The association of type 2 diabetes mellitus (T2DM) with the and genes in the Russian population has not been well studied. In this study, we analysed the population frequencies of polymorphic markers of these genes.

Methods: The study included 862 patients with T2DM and 443 control subjects of Russian origin.
