© 2016 Fedorenko and Bykova. Open Access terms of the Creative Commons Attribution 4.0 International License.The relevance of the topic is due to the need of self-correction of senior preschoolers. Adequate self-esteem of preschoolers will give us an opportunity to prepare them for school more effectively, as well as to create some positive character traits. The preschool age is the initial period of development of a child’s self-esteem. This is the most sensitive period for development of self-criticism and criticism to other people. During this period, it is important to lay down the foundation for formation of a differentiated adequate self-esteem and to correct it. This article is aimed to solve the problem of correction of senior preschool children self-esteem by the psychologist. The leading method of the research is the psycho-pedagogical experiment, thanks to which some special conditions for self-esteem correction were created. This article describes the developed and implemented program of senior preschool children self-esteem correction by the psychologist, where a set of games and exercises, dramatizations of literary works, art therapy techniques, psychological techniques were used as means of correction. The material of this article can be useful for teachers and psychologists who work with preschoolers

Studying the structure and adhesion strength of thermal barrier coating

The structure and adhesive strength of thermal barrier coatings produced by successive deposition of layers is studied. The coating is applied in three layers: I) a diffusion aluminosilicide coating that provides protection against high temperature oxidation and corrosion, with a thickness of 50μm; ii) a metal sublayer providing a smooth transition from a metal coating to a ceramic one, with a thickness of 100 to 120μm; iii) a ceramic layer decreasing the temperature of the blades during operation, with a thickness of 70 to 100μm. The total coating thickness ranges from 0.17 to 0.27mm. It is shown that the second and third layers deposited by plasma spraying are quite dense, the porosity being less than 5 vol%. During tensile tests carried out on an Instron testing machine, the failure of glued samples was always detected in the adhesive joint. The adhesive strength of the applied epoxy-based adhesive was 12MPa; it can be stated that the adhesive strength of the coating is higher than 12MPa. © 2019 Author(s)

Ni-Based Catalysts for the Hydrotreatment of Fast Pyrolysis Oil

Catalytic hydrotreatment is an attractive technology to convert fast pyrolysis oil to stabilized oil products for co processing in conventional crude oil refinery units. We report here the use of novel bimetallic NiCu- and NiPd-based (Picula) catalysts characterized by a high Ni content (29-58 wt %) and prepared using a sol gel method with SiO2, La2O3, kaolin, ZrO2, and combinations thereof as the support, for the catalytic hydrotreatment of fast pyrolysis oil. The experiments were performed in a batch autoclave (1 h at 150 degrees C, 3 h at 350 degrees C, and 200 bar initial pressure at 350 degrees C). The catalyst with the highest nickel loading (58 wt % Ni) promoted with Pd (0.7 wt %) was the most active, yielding oil products with improved properties compared to the crude pyrolysis oil (lower oxygen content, higher solubility in hydrocarbons, and less tendency for coke formation). For all Picula catalysts, except the ZrO2-based catalysts, methane formation was considerably lower than for Ru/C, the benchmark catalyst in catalytic hydrotreatment of fast pyrolysis oil. To anticipate possible catalyst deactivation at very long times on stream, catalyst regeneration studies were performed using thermogravimetric analysis. Analyses of the regenerated catalysts (X-ray diffraction, high-resolution transmission electron microscopy, and Brunauer Emmett Teller surface area) showed the occurrence of active metal agglomeration.</p

GENETIC FORMATION FACTORS OF DAIRY EFFICIENCY AND QUALITY OF CATTLE MILK

Experimental results of studying the efficiency of cattle selection method use on a genotype are presented to technologies of industrial milk production. For carrying out researches three groups of cows of the Ural black-andwhite breed type from lines Sovering Reflexion, Vis Back Ideal, Montwick Chiftain were created, up to 20 heads in every. The comparative analysis of dairy efficiency and quality of cow milk of different linear accessory is carried out. Impact of linear accessory of cows on a milk yield in 305 days of lactation, the content in milk of fat and protein, a ratio in milk protein of replaceable and irreplaceable amino acids is defined. It is revealed that the Ballele a kappa casein is characterized by the high content of protein in milk with the best abomasal coagulability. 14.3% of cows of the line Montwick Chiftain and 8% Sovering Reflexion had a desirable genotype on kappa casein - Centuries. Protein content in cow milk with a genotype of BB exceeded milk-protein indicators of cows of other genotypes by 0.14-0.18%. By amount of irreplaceable amino acids cow milk of the line Vis Back Ideal was the best that exceeded value of this indicator in cow milk of the line Montwick Chiftain and Sovering Reflexion by 9.5% and 4.5% respectively. It is established that in cow milk with AA genotype the share of irreplaceable amino acids exceeded their content as a part of the general protein in cow milk with a genotype of BB and AB for 8.9 and 39% respectively. Keywords: milk, kappa casein, milk fat and protein, selection, genotype, amino acids

Половые отличия пула свободных аминокислот-нейромедиаторов у крыс Крушинского-Молодкиной

The study of the role of neurotransmitter systems in the pathogenesis of epilepsy is one of the priorities of epileptology. New data on the functions of free neurotransmitter-like amino acid in the central nervous system are of the greatest importance and determine the prospects for the development of novel effective anticonvulsants. It is widely believed in clinical medicine that epilepsy has distinct gender characteristics. The aim of this study was to investigate the gender peculiarities in the content of neurotransmitter amino acids in the brain of Krushinsky-Molodkina (KM) rats, which were used as model organisms for the study of genetically induced audiogenic epilepsy. The content of Asp, Glu, GABA, Gly, and Tau of the medulla oblongata, hippocampus and cerebral cortex were determined using high-performance liquid chromatography (HPLC) in intact KM rats, KM rats exposed to a series of epileptiform seizures, and Wistar rats (control group). Both the Wistar and KM rats had gender distinctions in the distribution of free amino acids among the investigated brain parts. The audiogenic epilepsy was characterized by smoothing gender differences as well as differences between the concentrations of free amino acids in the cortex and medulla oblongata, specific for Wistar rats. The changes observed in male rats after the set of seizures included the increase in GABA concentration and a decrease in the Gly level in all investigated brain parts, as well as the decrease of the Tau content in the cortex and hippocampus. At the same time, the Glu content in cortex increased, while the Asp level decreased. After 6 days of audiogenic stimulations the female KM rats demonstrated the increase in the Glu level in all investigated brain parts, the increase in Gly and Asp levels in hippocampus, and no changes in the GABA content. Thus, after the set of epileptiform seizures the KM rats achieved a new steady state of the studied amino acids pool, which differed in males and females. In this case, gender differences significantly changed after the seizures. © 2020 Russian Academy of Medical Sciences.

Skyrmion Hall Effect Revealed by Direct Time-Resolved X-Ray Microscopy

Magnetic skyrmions are highly promising candidates for future spintronic applications such as skyrmion racetrack memories and logic devices. They exhibit exotic and complex dynamics governed by topology and are less influenced by defects, such as edge roughness, than conventionally used domain walls. In particular, their finite topological charge leads to a predicted "skyrmion Hall effect", in which current-driven skyrmions acquire a transverse velocity component analogous to charged particles in the conventional Hall effect. Here, we present nanoscale pump-probe imaging that for the first time reveals the real-time dynamics of skyrmions driven by current-induced spin orbit torque (SOT). We find that skyrmions move at a well-defined angle {\Theta}_{SH} that can exceed 30{\deg} with respect to the current flow, but in contrast to theoretical expectations, {\Theta}_{SH} increases linearly with velocity up to at least 100 m/s. We explain our observation based on internal mode excitations in combination with a field-like SOT, showing that one must go beyond the usual rigid skyrmion description to unravel the dynamics.Comment: pdf document arxiv_v1.1. 24 pages (incl. 9 figures and supplementary information
