Results of based on attributive theories researches of social and psychological mechanisms and regularities related to specialty image formation during professional development have been considered in this paper. Specialty image definition is presented, attributive theoretical model of the specialty image and its mechanisms of personal, object and environmental attribution is described and justified.A technique of this research carrying out has been described in the paper too, and results of empirical research of the specialty image related to persons at professional development’s various stages (pupils of profile classes, students, specialists working on the chosen specialty) have been also stated in detail. The specialty image structure with description of attributive classes and their elements has been presented. Types of attributive mechanisms and their combinations which are inherent in each of the professional development considered stages are described in this work too. It has been shown which of these mechanisms are the most effective for formation of an adequate professional picture of the world.The author has also presented possible directions for optimization of vocational training process with participation of business and educational institutions for the best adaptation of young personnel in the professional environment

Comparative evaluation of therapy results in mild acne

Introduction. Mild acne is the most underestimated form of the disease.The aim of the study was to compare the results of external combination therapy with 15% azelaic acid gel + 1% clindamycin gel and benzoyl peroxide + clindamycin for mild papulopustular acne.Material and methods. An open comparative prospective observational study in parallel groups (12 weeks) included 96 people, 65 patients with mild papulo-pustular acne and a control group of 30 healthy individuals. Group I received 15% azelaic acid gel +1% clindamycin gel, group II – benzoyl peroxide gel + clindamycin. The number of acne elements, morphofunctional indicators of the facial skin, side effects were recorded.Results. As a result of treatment, the indicators of sebumetry significantly decreased: in group I in the T-zone 47.5 ± 11.3 units (p = 0.043) and in the U-zone 57.5 ± 6.3 units (p = 0.037), and in group II in the T-zone 37.1 ± 5.8 units (p = 0.015) and in the U-zone 48.7 ± 5.6 units (p = 0.027). The pore sizes decreased significantly: in group I in the T-zone 0.052 ± 0.010 mm (p = 0.046) and in the U-zone 0.054 ± 0.009 mm (p = 0.049), and in group II in the T-zone 0.039 ± 0.011 mm (p = 0.064) and in the U-zone 0.047 ± 0.013 mm (p = 0.041). In patients in group I, pigmentation indicators in the T-zone of 17.0 ± 2.8 units (p < 0.001) and the U-zone of 17.0 ± 2.8 units (p = 0.048) were normalized. In patients in both groups, there was a significant (p >< 0.05) decrease in the number of papulopustules.>˂ 0.001) and the U-zone of 17.0 ± 2.8 units (p = 0.048) were normalized. In patients in both groups, there was a significant (p ˂ 0.05) decrease in the number of papulopustules.Conclusion. When comparing the results of therapy with 15% azelaic acid gel + 1% clindamycin gel and benzoyl peroxide + adapalene for mild papulopustular acne, comparable efficacy and safety were revealed

Deformation uniformity of additively manufactured materials on the example of austenitic stainless steel 321 and copper C11000

Structural studies and mechanical tests of additively manufactured samples from AISI 321 steel copper C110000 have been carried out. Mechanical tensile tests of 321 steel show slight differences in the ultimate tensile strength (up to 3-4%) and ductility (up to 10%) of test coupons tested along the material growth direction and along the layer deposition direction. The strength of C11000 copper samples is 9.4% higher in the layer deposition direction, but their ductility is 15.4% lower than that of samples deformed in the growth direction. The strain relief on the surface of the polished gage section of the steel test coupons demonstrates changes in the material structure with small elongated grains along the growth direction of the sample. The deformation relief of copper samples is mainly related to the deformation of large columnar grains stretched in the growth direction

Polarity and conformational analysis of secondary phosphine selenides

The polarities of bis(2-phenylethyl) and bis(2-phenylpropyl) phosphine selenides were determined and conformational analysis of these phosphine selenides was carried out by the method of dipole moments, IR spectroscopy, and quantum chemical calculations. They exist as an equilibrium of several conformers, and the preferred conformers have gauche orientation of the P = Se and Csp3 - Csp3 bonds. © 2013 Copyright Taylor and Francis Group, LLC

Polarity and structure of derivatives of bis(2-phenylethyl)selenophosphinic acid

© 2017 IUPAC & De Gruyter.Conformational analysis of derivatives of bis(2-phenylethyl)selenophosphinic acid was carried out by the method of dipole moments and density functional theory calculations. The conformations of the examined compounds fit into the overall conformational picture for the PIV compounds: These derivatives exist as conformational equilibrium of non-eclipsed gauche and trans forms with propeller arrangement of the substituents relative to the P=Se bond. We stipulate that the eclipsed cis orientation of substituent may be caused by the formation of H-contact

Thermodynamic properties of myo-inositol

© 2017 Elsevier Ltd In the present work, the temperature dependence of heat capacity of vitamin B8 (myo-inositol) has been measured for the first time over the range from 8 K to 340 K by precision adiabatic vacuum calorimetry. Based on the experimental data, the thermodynamic functions of the vitamin B8, namely, the heat capacity, enthalpy H°(T)–H°(0), entropy S°(T)–S°(0) and Gibbs function G°(T)–H°(0) have been determined for the range from T → 0 K to 340 K. The value of the fractal dimension D in the function of multifractal generalization of Debye's theory of the heat capacity of solids was estimated and the character of heterodynamics of structure was detected. The enthalpy of combustion (−2747.0 ± 2.1) kJ·mol−1 of the vitamin B8 was measured for the first time using high-precision combustion calorimeter. The standard molar enthalpy of formation in the crystalline state (−1329.3 ± 2.3) kJ·mol−1 of B8 at 298.15 K was derived from the combustion experiments. Using combination of the adiabatic and combustion calorimetry results the thermodynamic functions of formation of the myo-inositol at T = 298.15 K and p = 0.1 MPa have been calculated. The low-temperature X-ray diffraction was used for the determination of coefficients of thermal expansion

Structure formation features of large block-shaped samples from the copper and aluminum alloy produced by the wire-feed electron-beam additive technology

In this work the study of the structure of samples made by the wire-feed electronbeam 3D printing from copper C11000 and aluminum alloy AA5056 was carried out. The presence of a dendritic structure typical of this method was revealed, as well as the presence of pores, cracks and other defects that occurred during printing. Mechanical properties of samples cut in the planar section are at a rather low level. The ultimate tensile strength of copper block samples varies between 165 and 187 MPa. The relative elongation of samples without pores is at 18%, but with the presence of pores it decreases sharply to 7%, while the strength is practically not decreased. The samples of alloy AA5056 demonstrate slightly higher mechanical properties: the strength is at the level of 190-192 MPa and the relative elongation is about 16-18%. In samples with defects such as large pores or discontinuities, the strength drops to almost zero

© 2016 Elsevier LtdIn the present work, temperature dependence of heat capacity of methylprednisolone aceponate has been measured for the first time over the range from 7 K to 346 K by precision adiabatic vacuum calorimetry. Based on the experimental results, the thermodynamic functions of the methylprednisolone aceponate, namely, the heat capacity, enthalpy H°(T)−H°(0), entropy S°(T)−S°(0) and Gibbs function G°(T)−H°(0) have been determined for the range from T/K → 0–333. The enthalpy of combustion (−14304.4 ± 9.1) kJ·mol−1 of the methylprednisolone aceponate was determined for the first time using high-precision combustion calorimeter. The standard molar enthalpy of formation in the crystalline state (−1465.3 ± 9.8) kJ·mol−1 of compound at 298.15 K was derived from the combustion experiments. Using a combination of the adiabatic and combustion calorimetry results the thermodynamic functions of formation of the folic acid dihydrate at T = 298.15 K and p = 0.1 MPa have been calculated
