Abstract

The paper considers the problems of physical modification of starch products and other food ingredients. The main trends and directions of innovative activity characteristic of the ingredient market have been described. As a result of the experiments, a method for modifying starches, starch products and complex food additives has been developed to improve their microbiological, physicochemical and organoleptic characteristics. It has been proven that when exposed to infrared radiation with a wavelength of 7–10 microns on a layer of a product 1 cm thick for 1 minute, the number of mesophilic aerobic and facultative anaerobic microorganisms in such a product is reduced to zero. At the same time, the mass fraction of reducing substances as a result of such treatment more than doubles, which indicates the occurrence of the dextrinization process. It is possible to process both starch products that act as carriers in complex mixtures and ready-made additives after completion of the mixing process. The mass fraction of moisture during infrared processing decreases by less than 1 % for maltodextrins and by less than 2 % for complex food additives, which characterizes the resulting technological losses as acceptable. Changing the granulometric composition of complex additives under the influence of infrared radiation improves the flowability of the product, increases the uniformity of distribution of flavoring substances over the surface of the carrier, which in turn makes it possible to reduce the dosage of complex additives in the manufacture of meat and confectionery products. Based on the results obtained, technological diagrams have been developed and described showing the production process step by step, indicating all significant parameters.

Abstract

The Molnieboi Spur is located at the northwestern margin of the Katun Range, the high-mountain part of the Altai Mountains. Unique geological and geophysical characteristics of the Molnieboi Spur made it an attractive target for complex botanical studies including botanical, soil, geological, geochemical, geophysical, radiation, and soil gas surveys and analyses. In this paper, we present the first version of the geographic information system (GIS) application for the Molnieboi Spur developed using the software QGIS. A digital elevation model for the study area was derived from a detailed topographic map. The database was filled with tabular data on about 100 parameters including: eight botanical characteristics of the Lonicera caerulea local population, two cytogenetic indices of Lonicera caerulea seeds, five types of biochemical parameters of Lonicera caerulea leaves and fruits, three types of geochemical characteristics of the local soils, three types of radiation parameters of the local soils and Lonicera caerulea plants, and one soil gas parameter. The results of the magnetometric survey were inserted as a raster image. A visual analysis of the maps produced allows one to better understand the spatial relationships between various natural components of the Molnieboi Spur., Comment: 10 pages, 7 figures (corrected text, references added)

14. Industrially Scalable Process for Silicon Nanowires for Seebeck Generators

Abstract

The observation that the thermal conductivity of single-crystalline silicon nanowires with diameter on the length scale of 25 nm is lower than that of bulk material by two orders of magnitude has attracted the interest onto silicon as a potentially effective thermoelectric material. However, the potential interest has a hope of transforming in a practical interest only if poly-crystalline silicon can replace single crystalline silicon and the preparation of nanowires does not involve any advanced photolithography. In this work we show that a technique, based on the controlled etching and filling of recessed regions and employing standard photolithography and deposition-etching methods, succeeds in the preparation of poly-crystalline silicon nanowires (with diameter of 25 nm and length on the centimetre scale) at a linear density of 3E6 cm^-1.

Abstract

The paper examines the socio-psychological determinants of the behavior of medical workers during the coronavirus pandemic. The parameters of personal determination of actions in various situations and options for interaction with them by medical workers are analyzed. The coping strategies used by health care workers to survive in conditions of increased stress and maintain their psychological health and well-being, exercising their competencies in the red zone, are being explored., В работе рассматриваются социально-психологические детерминанты поведения медиков при пандемии коронавируса. Анализируются параметры личностной детерминации действий в различных ситуациях и варианты взаимодействия с ними медицинских работников. Исследуются копинг-стратегии, используемые сотрудниками учреждений здравоохранения для выживания в условиях повышенного стресса и сохранения своего психологического здоровья и благополучия, осуществляя свои компетенции в красной зоне., Человеческий капитал, Выпуск 5 (173) 2023, Pages 254-264
