New Technologies of Matrix Composite Polymer Photovoltaic and Photoresistive Materials

The goal of the paper is development of more effective technology formation photovoltaic and photoresistive elements based on the polar and nonpolar polymers dispersed by CdS, ZnS, CdSe and CdTl particles. It was established that: 1. The interphase interaction in photoelectric composites on the interphase boundary is considerably depended on particle size of inorganic phase; 2. Polymer matrix is not passive phase in photoelectric composites, but defines a value of Rdark resistance/Rlight resistance parameter and value of photo-emf; 3. 3. Plasma crystallization of photoelectric composites is accompanied by formation of local levels with high concentration and activation energy in quasi-forbidden band of polymer matrix; 4. Doping of ferroelectric component with domain structure into photoelectric composite of polymer-CdS leads to increasing concentration of centers of local electric fields promoted division of photoinduced charges

Pathomorphological Changes in Poultry Pasteurellios, Pullorosis and Colibacteriosis Diseases

The organism of chicken infected with individual pathogens exhibits relatively simple patho-anatomical modifications in the presence of two or three separate bacterial pathogens. Because it is highly challenging to differentiate between mixed bacterial infections based just on clinical symptoms, pathologoanatomical examination and distinction are preferred. These disorders will be accurately diagnosed promptly and without delay if the pathologo-anatomical investigations are properly examined, and preventive measures will be consistently applied

RESEARCH OF THERMAL STATUS OF THREADING ZONE WITH THE HELP OF FULL FACTOR EXPERIMENT

Thermal processing zone status when threading in heatproof, high-strength and titanium alloys is a major problem in the general theory of metal cutting. Under other equal conditions temperature in the processing zone of these materials is higher than in cutting of carbon structural steels, as they have high strength and ductility, low thermal conductivity, that makes difficult the working conditions of the taps, increases the area of the tool contact with the workpiece, deteriorates lubrication and cooling of the cutting area because of the increased tendency of heatresistant materials for the curing. This causes an increase in the work and force of friction and as a consequence the rise of cutting temperature. Research of temperature state of the threaded coils formation zone with combined countersink tool-tap is one of the major challenges facing the authors of this work. When performing the work was used factorial experiment. The temperature in the cutting zone of the thread was determined by a built-in chromel-aluminum thermocouple with thermoelectrode cross-sectional area 0,23mm2 . Experiments were carried out using the apparatus of mathematical statistics. Studies have shown that the greatest impact on the temperature state of the cutting area has a tensile strength of the material. Effect of cutting speed in the studied variation range is relatively less noticeable. The explanation for this is a special scheme of cutting of combined countersink tap which allows significantly improve conditions in the cutting zone. The proposed design of the tap allows to reduce the temperature in the area of tapping for 20%

STUDENT ATTITUDE TO DEMOGRAPHIC SITUATION IN RUSSIA

Purpose of the study: Since the new generation is the main entity of material and social benefits’ renewal process of any state, the article aims to identify the students’ attitude to the demographic situation in Russia. It is the younger generation of different age groups that is the main labor unit of the state population. Relevant is the fact that the issues of demography are a global challenge of self-organizing society.  The purpose of the article is to identify the students’ attitude to the demographic situation in Russia, as well as to consider various models of reproductive behavior. Methodology: The leading methods for the study of this problem is the survey method, which allows to make a qualitative analysis of the characteristics of the students’ attitude to the demographic situation in Russia and to establish the subjective position of students regarding demographic development. Results: The article reveals that the following administrative and legal measures contribute to the improvement of the demographic situation in the country (legislative acts regulating the marriage age, divorce, attitude to abortion and contraception, the status of mother and children in the divorce, working women’s labor regime); economic measures (paid leave, various benefits at child’s birth, preferential credit conditions if necessary, tax and housing benefits); educational measures (formation of public opinion, the core and standards of demographic behavior, determination of attitude to religious norms, traditions and customs, family planning policy, sexual education of youth). The authors established a high level of awareness of students about the demographic situation in the country; the presence of anxiety about this situation. Applications of this study: The data obtained in the work can be used in sociology, social psychology, political science, as well as for further theoretical development of this issue. Novelty/Originality of this study: The study revealed a high level of awareness of young people about the demographic situation in the country, certain anxiety about this situation. However, young people are not in a hurry to participate in the solution of demographic problems, referring mainly to the difficulties of material nature. This indicates the need for more careful consideration of measures of state support for young families, taking into account the research of their opinion on this matter

Atmospheric Chemistry in Giant Planets, Brown Dwarfs, and Low-Mass Dwarf Stars II. Sulfur and Phosphorus

Thermochemical equilibrium and kinetic calculations are used to model sulfur and phosphorus chemistry in giant planets, brown dwarfs, and extrasolar giant planets (EGPs). The chemical behavior of individual S- and P-bearing gases and condensates is determined as a function of pressure, temperature, and metallicity. The results are independent of particular model atmospheres and, in principle, the equilibrium composition along the pressure-temperature profile of any object can be determined. Hydrogen sulfide (H2S) is the dominant S-bearing gas throughout substellar atmospheres and approximately represents the atmospheric sulfur inventory. Silicon sulfide (SiS) is a potential tracer of weather in substellar atmospheres. Disequilibrium abundances of phosphine (PH3) approximately representative of the total atmospheric phosphorus inventory are expected to be mixed upward into the observable atmospheres of giant planets and T dwarfs. In hotter objects, several P-bearing gases (e.g., P2, PH3, PH2, PH, HCP) become increasingly important at high temperatures.Comment: 38 pages, 8 figures, accepted for Astrophysical Journa
