IMPROVEMENT OF WORKING CONDITIONS IN RURAL AREAS THROUGH THE FORMATION OF INFRASTRUCTURE FOR AGRICULTURAL SERVICES

Relevance of the study. The infrastructure of rural settlements has a significant impact on the quality of life of the rural population and, as a result, on the development of the infrastructure of the agro-industrial complex. Objective. The purpose of this study is to develop scientific and methodological provisions for improving the infrastructure of agricultural services. Materials and methods. The research methodology includes bibliographic analysis, as well as analysis of statistical data. To identify the most significant factors for ordinary agricultural workers, the method of expert assessments is used. Results. Studies have been conducted on the agro-industrial complex organizations of the Altai Territory. The main part of the article identifies external and internal factors that determine the quality of working conditions in agriculture. Using the method of expert assessments, the most significant factors for ordinary agricultural workers were identified. In order to introduce digitalization in the agro-industrial complex, software and hardware unmanned complexes designed to perform certain functions in crop production are considered. Digital solutions designed to perform the functions of interaction with suppliers, consumers and transportation of agricultural products are described. The issues of environmental safety of workplaces in the agro-industrial complex are considered. Conclusion. It is revealed that in order to effectively develop the infrastructure of rural settlements as a tool to improve the quality of life of the rural population, it is necessary to abandon the policy of maximum coverage in favor of a policy of concentrating efforts on a certain territory on the basis of a comprehensive plan covering all spheres of society and involving sectoral authorities in its implementation within a single project

Errors in shaping by a planetary mechanism

© 2017, Allerton Press, Inc. The proposed planetary reaming method permits discontinuous turning in which the cutting edge moves relative to the cutting surfaces. As a result, individual sections of the cutting zone move successfully in and out of the machining zone. Discontinuous turning is free of the deficiencies of continuous turning

COSMETOLOGICAL SIGNIFICANCE PROBLEMS OF ANATOMY, EMBRYOLOGY AND STRUCTURAL AND FUNCTIONAL UNITS OF SKIN (TO HELP PRACTICING PHYSICIANS: PART 2)

The subject of the study – the features of skin’s embryology and histology. The purpose of a work – to present the problematic issues of skin’s anatomo-hystological structure. The analysis of modern scientific studies testifies to necessity for scrupulous accountancy of skin’s structure components development both in pre- and postnatal periods of human life. It will allow to avoid many clinical mistakes and provide pathogeneticly well-grounded correction of skin’s variable changing, both pathological and «cosmetological».Keywords: skin, histology. Предмет исследования – особенности гистологии кожи. Цель – представить врачам проблемные вопросы анатомо-гистологического строения кожи. Анализ современных научных исследований свидетельствует о необходимости тщательного учета развития структурных компонентов кожи на этапах как пре- так и постнатального периодов жизни человека. Это позволит избежать многих клинических ошибок и проводить патогенетически обоснованную коррекцию различных ее изменений, как патологических, так и «косметологических».Ключевые слова: кожа, гистология

«LIFE QUALITY» INDICATORS IN PATIENTS WITH CHRONIC DERMATOSIS

The subject of the study – the analysis of «life quality» indicators in patients with chronic dermatosis. The purpose of a work is to compare «life quality» indicators in patients with rosacea and psoriasis with complicated and uncomplicated forms of the disease. The research is conducting with the WHOOOL-BREF Quiz – an analysis of four basic spheres, characterizing different aspects of life quality indicators of patients with rosacea and psoriasis testifies to reliable differences of the majority of scores in examined patients, comparing with average scores in «healthy people»; more pronounced differences were mentioned in complicated forms of these and others dermatosis.Keywords : rosacea, psoriasis, demodecosis, arthropathia, life quality.  Предмет исследования – анализ показателей качества жизни у больных хроническими дерматозами. Цель работы – сравнить показатели качества жизни больных розацеа и псориазом с осложненными и не осложненными формами течения заболевания. Проведение с помощью опросника ВОЗ (WHOOOL-BREF) – анализа 4 основных сфер, характеризующих различные аспекты качества жизни больных розацеа и псориазом свидетельствует о достоверных отличиях по большинству изученных показателей у обследованных больных по сравнению со среднестатистическими коэффициентами у «здоровых лиц»; более выраженные отличия наблюдались при осложненных формах этих и других дерматозов.Ключевые слова: розацеа, псориаз, демодекоз, артропатия, качество жизни

Investigation of β + β + and β + /EC decay of 106 Cd

A low background scintillation detector with a CdWO4 crystal of 1.046 kg was used to search for β+β+ and β+/EC processes in 106Cd. For the neutrinoless mode the limits T1/2(0νβ+β+) ≥ 2.2 · 1019 y and T1/2(0νβ+/EC) ≥ 5.5 · 1019 y were obtained with 90% C.L. For the possible two neutrino decay limits of T1/2(2νβ+β+) ≥ 9.2 · 1017 y and 1/2(2νβ+/EC) ≥ 2.6 · 1017 y have been determined with 99% C.L

Solubility of Rock in Steam Atmospheres of Planets

Extensive experimental studies show that all major rock-forming elements (e.g., Si, Mg, Fe, Ca, Al, Na, K) dissolve in steam to a greater or lesser extent. We use these results to compute chemical equilibrium abundances of rocky-element-bearing gases in steam atmospheres equilibrated with silicate magma oceans. Rocky elements partition into steam atmospheres as volatile hydroxide gases (e.g., Si(OH)4, Mg(OH)2, Fe(OH)2, Ni(OH)2, Al(OH)3, Ca(OH)2, NaOH, KOH) and via reaction with HF and HCl as volatile halide gases (e.g., NaCl, KCl, CaFOH, CaClOH, FAl(OH)2) in much larger amounts than expected from their vapor pressures over volatile-free solid or molten rock at high temperatures expected for steam atmospheres on the early Earth and hot rocky exoplanets. We quantitatively compute the extent of fractional vaporization by defining gas/magma distribution coefficients and show that Earth's subsolar Si/Mg ratio may be due to loss of a primordial steam atmosphere. We conclude that hot rocky exoplanets that are undergoing or have undergone escape of steam-bearing atmospheres may experience fractional vaporization and loss of Si, Mg, Fe, Ni, Al, Ca, Na, and K. This loss can modify their bulk composition, density, heat balance, and interior structure
