    Get PDF
    Progress in the field of thermoelectricity requires the further development of material science deep into the substance through the use of the achievements of applied and theoretical advances in nanotechnologies, including nanothermodynamics. This enables to expand the range of current thermodynamic forces, taking into account the forces inherent in nanostructured substances, and to increase the efficiency of attracting the concept of eddy thermoelectric currents in order to increase the accuracy of temperature measurement by thermoelectric sensors. The researches of materials of thermoelectric sensors have not only included not only the study of the stability of thermoelectric sensors, but their study by their methods of non-destructive acoustic control. This makes it possible to assess and develop the role of specific mechanisms for the formation of eddy thermoelectric currents in the drift of thermoelectric power

    The quantum standard of temperature based on the revealed quantum unit of the mentioned quantity is studied. It is recommended first to apply as an intrinsic standard. Such a standard does not need permanently recurring measurements against the realization of the SI unit to validate its accuracy. It may be considered as the intrinsic standard of temperature that could be embedded into cyber-physical systems (CPSs) ensuring their precision operation. The methodological base of involvement of the developed standard in the formation of the thermoelectric power of thermoelectric transducers as well as the generator is considered. The feasibility of a unified consideration of the nature of thermoelectric power within macro- and nanothermodynamics is shown. This approach is driven by the increasing use of nano elements based on 1D-, 2D- nanomaterials (nanowires and nanosheets, respectively) and nanostructured materials in technology, in particular, to improve the key parameters of thermoelectric generators and thermometers. In the first case, this is thermoelectric efficiency, and in the second case, the accuracy of thermometers, which is determined by the stability in a time of thermoelectric power

    The research used the seeds of long flax of the "Vruchy" variety and oil-curly flax of the "Original" variety. To extract mucus, whole flax seeds were hydrated for 3 hours. in tap water, at a ratio of 1:20 and a temperature of 18 – 20 °C with constant stirring with a magnetic stirrer. This study aimed to evaluate the effect of temperature and duration of extraction on the yield of mucilaginous polysaccharides in aqueous solution from flaxseed. Change range: the temperature is selected in the range from 0 °С to 100 °С with a step of 20 °С; with a duration, ranging from 10 min to 140 min in 10 min increments. The yield of polysaccharides from flax seeds was determined for each combination of controlled factors. It was established that in the first 10 – 20 min. there is an increase in the yield of polysaccharides and the rate slows over time. For 90 min. equilibrium occurs at a temperature of 80 °C. This period of the process is optimal for the extraction of mucilage-forming polysaccharides from flaxseed. The mass of the extracted polysaccharides, from the mass of the seeds after a time of 95 min was 5.74%, and 6.00% at a temperature of 80 °С. A package of applied statistical programs was employed during the research to process the experimental data. A mathematical model of the process of extracting mucus-forming polysaccharides in an aqueous solution of flax seeds was built using regression analysis methods. The obtained regression equations determined the optimal regimes of the sought values in terms of temperature (80 – 85 °C), time (85 – 90 min) and conducted in compliance with the prescribed amount of water of 200 cm3. Within 10 – 20 min the formation of a transparent gel capsule around the flax with a phase separation boundary under seed contact with water, which does not change further. This indicates the completion of the hydration process

    Purpose. The purpose of this paper was to determine motivational factors of structural changes in the agro-industrial sector of Ukraine, which will strengthen the ability of business entities to generate larger added value flows and increase efficiency through the development of strategic network partnerships. Methodology / approach. While writing the article the following methods were used: methods of economic and statistical analysis – to study the dynamic of indicators that reflect the results of sectoral structural changes of the enterprises’ activities in the sector of agriculture, forestry and fisheries of Ukraine during 2016–2019; critical analysis – to identify shortcomings in the legislative field of Ukraine, which deform motivational vectors, negatively affect the development of agro-industrial complex; morphological analysis and synthesis – to prove the feasibility of interpreting the term “network capital” in a narrow and broad sense; scientific abstraction and graphic visualization – to build the model of formation of network capital and use in the processes of organizational interaction of participants in a strategic business partnership; mathematical modelling – to formalize the conditions under which the network partnership participants will avoid manipulation by the expert environment in the apportionment of the costs and revenues from the implementation of business projects. Results. It has been studied the dynamic of indicators that reflect the results of the sectoral and structural changes in activities of Ukrainian enterprises in the agriculture, forestry, and fisheries sector during 2016–2019. It has been highlighted shortcomings in the legislative field of Ukraine, which distort the vectors of motivational influence on the development of agro-industrial complex, causing the corruption schemes spread in the decisions and actions of economic agents. The essential content of the term “network capital” in a narrow and broad interpretation has been differentiated and the motivational basis for its increase by the business network participants has been highlighted. The processes of formation and use of network capital in the inter-organizational interaction of participants of strategic business partnership have been modelled. Nash equilibrium theory has been applied to increase the reliability of the position assessment of business network participants in the total costs and revenues apportionment and it has been proved that this forms the motivational basis for long-term cooperation. Originality / scientific novelty. The author’s interpretation of the term “network capital” in a broad and narrow sense with emphasis on motivational aspects of this capital increasing in the agro-industrial business network has been proposed. The model of network capital formation and use in the processes of organizational interaction of participants in a strategic business partnership has been constructed. There have been modelled the conditions under which the participants of the network partnership will avoid manipulation by the expert environment in the apportionment processes of costs and revenues from the business projects implementation, which will improve their motivation to cooperate. Practical value / implications. The main results of the study can be used for (i) elimination of some gaps in the institutional environment of Ukraine, which distort the motivational vectors of agricultural development; (ii) managing growth processes of network capital to increase the aggregate ability of business network participants to create new consumer value with high added value; (iii) improving the motivational basis for long-term cooperation of business network participants by increasing the reliability of their positions assessment in the total costs and revenues apportionment
