Software and methodological support for theorizing the prospects for the development of higher technical education in the system of training civil engineers are determined in the system of continuing education as a future solution to the problems of increasing the efficiency of management of professional training of scientific and pedagogical workers in the system of continuous engineering and construction education
The Influence of Climate Changes on Mudflow Formation in Permafrost Areas: a Case Study for Chukotka Peninsula
The factors influencing the formation of mudflows in areas of the permafrost are considered. The data of studies performed in two regions of Chukotka – “Continental” (the Anyuysky ridge) and “Coastal” (the Iskaten ridge) were used for this research. The air temperature data series obtained in Chukotka in 2000–2020 demonstrate a steady growth of the average annual values. The air temperature rise estimated for the mudflow–dangerous period (June–August) amounted 1.4°C for the “Continental” area, and 1.0°C for the “Coastal”. This warming affects thickness of the seasonal melt layer of permafrost, mainly in the bottoms of valleys and on the slopes of mountains. This factor promotes the involvement of certain volumes of ground into mudflows. As a result of the research, it was found that the dynamics of the change in the thickness of the seasonal melt layer within the studied areas is positive, which is a consequence of warming and leads to additional moistening of grounds. The two periods of the mudflow formation were identified. During the first one (May–June), the mudflow formation is connected with the onset of intensive snowmelt that is favorable mainly for snow-water streams and loose mudflows. In the second period (July–August), mudflows are mostly caused by liquid precipitations, when the maximum thickness of seasonal melt layer is reached. It is the second period when a release of a large cohesive mud stream is the most probable. On the whole, the results obtained allow making a conclusion that in the near future the predominant type of mudflows in Chukotka will remain those of snow genesis. But, at the same time, under conditions of the climate change, occurrence of the snow-water mud streams will increase, especially in the “Coastal” area
Transporting Particles with Vortex Rings
Due to their long-lived nature, vortex rings are highly promising for
non-contact transportation of colloidal microparticles. However, they are
complex structures, and their description using rigorous, closed-form
mathematical expressions is challenging, particularly in the presence of
strongly inhomogeneous colloidal suspensions. This study presents
straightforward analytical approximations that reveal the dynamics of vortex
rings transporting microparticles. Our results were validated using
comprehensive simulations and experimental measurements.Comment: did not participate in the final publication due to different

The effect of herbal supplements on development of internal organs and chemical composition of broilers muscles
The present article presents data on effectiveness of adding a phytobiotic feed additive into the diet of broiler chickens, either additionally or replacing the feed antibiotic in the chicken fodder. It has been established that the introduction of a phytobiotic feed additive into the broilers’ diet, both additionally and by replacing the feed antibiotic, provided positive effect on poultry meat quality and gave no negative effect on development of internal organs. By the end of fattening the relative weight of heart, lungs, kidneys, gizzard and intestines in broilers, which consumed the antibiotics-free diet with addition of researched preparation, was higher than in the control group and in the 1st experimental group. At the same time the length of the intestine in researched group significantly exceeded the control group parameters. These changes ranged within the physiological norm, which may indicate the best detoxification capabilities of the chicken body and the activation of enhanced intestinal absorption function. Additional use of the experimental feed additive in formulation of feed for broiler chickens was accompanied by a decrease in total amount of amino acids in broilers’ pectoral and leg muscles within acceptable physiological limits. At the same time, a significant decrease, compared with the control parameters, was noted in relation to content of histidine and isoleucine in pectoral muscles, and content of proline in leg muscles. The use of the researched additive as a substitute for a feed antibiotic in composition of mixed feed for broilers decreased the total amount of amino acids in broilers’ breast muscle, compared with the control group, and increased level of amino acids in leg muscles. The significant decrease in content of histidine and arginine in the pectoral muscles and proline in the leg muscles was noted. The observed changes varied within acceptable physiological norm. In the experimental groups the energy value of meat was increased
