Calculation of large-span glulam structures as a soil base-foundation-above-ground structure system
Full text linkThe object of research. Long-span glulam arches are widely used as coatings for public and sports buildings. The studies carried out concern double-hinged segmental arches with spans of 60 m and more.
Description of the problem. The study of the peculiarities of the work of arches as a system "soil base - foundation - above-ground structure" is associated with the significant influence of uneven deformations of supports on the stress-strain state of the above-ground structure. A change in the stress-strain state in the structure itself, associated with uneven deformations of the foundations, can lead to a significant decrease up to the complete exhaustion of the bearing capacity
Main scientific results. This article provides an analysis of the change in the stress-strain state of glulam arches when calculating the system "soil base-foundation-above-ground structure". It is noted that non-uniform deformations of supports have the greatest influence on the stress in the support zones of the structure. The range of critical non-uniform subsidence has been determined, which should be limited when calculating and designing the foundations of large-span arches. It has been confirmed that double-hinged glulam arches work well in conditions of uneven subsidence due to the peculiarities of the design scheme.
The results of the studies carried out and the recommendations provided will significantly improve the reliability of large-span structures and require mandatory inclusion in the current practice of calculation and design. In addition, additional requirements for the distance between mine workings for large-span structures should be introduced when performing engineering and geological surveys. This distance should be reduced for a clearer account of the deformability of the foundations for columnar foundations, and the number of workings should be increased.
The area of practical use of the research results. The cross-section of the glulam arches is selected taking into account additional deformations of the supports, making it possible to avoid unpredictable damage to the structure during operation.
Innovative technological product. Glulam arches, the cross-section of which is determined taking into account additional deformations from uneven subsidence of the supports
Scope of application. Glulam arches calculated in this way can be used as covering for public and sports buildings for various purposes

Four factors are in force pandemic joints to initiate an illicit dual use technologies transfer from Ukraine
Full text linkAn objective of this effort is a quick recap to assess the underpin barriers of transfer of technologies appeared in Ukraine after acquiring the Independence and those developed of today and to highlight and evaluate an impact of political, historical, mental and other factors affecting the science and as a consequence leakage of technologies abroad. Of importance is also a question if a current COVID-19 pandemic will join these factors if it initiates an illicit transfer of dual use (DU) technologies from Ukraine as it was in 1990s and how it affects an efficient and proper functioning and optimization of transfer of technologies process, and that is quite a challenge nowadays.
Investigated problem. The process of technology transfer and specifically that one of DU as a whole is neither simple nor systematic and far from being that perfect, especially when it deals with dual-use technologies and at present reduced to a short relationship between supplier/recipient only. The experience and practice show that it is a rather complicated, multi-leveled and multi-players process which is impacted and follows several factors and conditions that determine its success and/or failure at the end.
The main scientific results. The development of dual use technologies continues in a quagmire of conflicting interests and technology transfer export control rationales. There are historical, mental and political-military considerations where a state’s decision to develop weapon systems or related applications can be assessed not only as a function of perceived levels of threat to its security, but also as a need to respond and/or step forward to potential technological innovations; and second, the fundamental conceptual differences in appreciation among countries of the right to possess different advanced weapons systems for defensive or offensive purposes.
The result of this endeavor makes a solid ground floor for further debates in terms of political science, export control regulations and factors affecting transfer of sensitive technologies
Study of rheological characteristics of fermented milk paste with spices
Full text linkResearch object: rheological characteristics of fermented milk pastes with spices.
Investigated problem: according to the results of the degree of syneresis and rheological properties, the consistency of the product is characterized. This allows to improve and optimize the technological process for the production of fermented milk products.
Main scientific results: the results of the dispersion analysis of spices show that their particle size is in the range of 250 … 400 microns. This size is optimal for the extraction of biologically active substances of spices, which will contribute to greater assimilation by the human body. And also optimally to avoid caking of raw materials and the manifestation of moisture-absorbing properties.
It was found that the degree of syneresis of fermented milk pastes with spices is within 10 %. With the addition of cinnamon and fenugreek spices, the degree of syneresis is lower compared to other examples. This is due to the fact that spices contain a solution of fiber, which allows them to retain free moisture. The spice cinnamon is a dried bark that naturally contains polysaccharides, while fenugreek contains up to 30 % mucus, which also has a high moisture-absorbing capacity. With such a low serum separation, the stabilizing effect is sufficient to prevent spontaneous whey separation.
Based on the results of the rheological properties of the product, it was established that fermented milk pastes belong to viscoplastic systems with a normal consistency. There was a slight difference in the shear stress index for pastes based on fermented milk low-fat soft dietary cheese and sour cream with a fat mass fraction of 20 % – by an average of 50 Pa. This characteristic is due to the hydrophilic characteristics of the protein.
The area of practical use of the research results: scientific research concerns the technology of dairy products in the food industry.
Innovative technological product: the obtained scientific result is an opportunity to improve the technological process of fermented milk products.
The scope of implementation of an innovative technological product: the results obtained give grounds to assert the ability to translate into a real industrial creation
