THE PREDICTION OF WATER CUTTING AND DENSITY OF OILWATERCONDENSAT MIXES

This article is devoted to studying of problems, existence of a significant amount of gas-condensate deposits of Azerbaijan causes high prospects of use of condensate also as a thinner at pipeline transport high-viscosity flooded by the crude oil. Finds relevance of an assessment of influence of concentration and viscosity of a thinner – condensate on physical and chemical characteristics of petrowater condensate mixes at various temperatures and the modes of currents. It is well-known the facts that availability of the dispersed water in petrocondensate mix reduces efficiency of operation of pipelines. So, the increase in volume of water and raised viscosity leads to rise in price of transportation by petrowater condensate mix. Besides the high content of the connected water in mix causes intensive education by asfaltqamparafin postponed, increases oil hardening temperature. On it regular control for changes of noted parameters (degree of water content and density of mix) is of great importance. Considering the aforesaid, for an assessment of influence of the content of condensate on reophysics indicators transported bypass crude oil at various temperatures laboratory researches were conducted. On the basis of the obtained data on test various petrowater condensate mixes were offered empirical a formula for determination of their water content and density. The analysis showed that the offered empirical models in comparison with the rule of additivity yield more acceptable results from the point of view of practice and will well be coordinated with data experimental defined the distinguished parameters

Epizootiological characteristics of echinococcosis in dogs, sheep and goats and measures to combat it in Caspian Sea region of Russia

The paper presents the results of the study of the epizootiological characteristics of echinococcosis in dogs, sheep and goats in the Caspian Sea region of Russia where Echinococcus occurrence varies from 30 to 80%, as well as the results of tests of the complex product Prazibars (at different doses) for its effectiveness against this parasitosis. The extensity of Echinococcus invasion in sheep and goats in the Caspian Depression is 38.6%; it is expansive and affects more and more areas. Some researchers report that Echinococcus granulosus occurrence in sheep in the Caspian Sea region of Russia increases by 0.2–0.3% annually and averages 32.8%. It is demonstrated that Echinococcus granulosus invasion intensity and extensity in sheep dogs in the natural altitudinal zones of the region average 3,136.7 ± 343.0 par­asites/animal and 30.1%, respectively. In the zones covered by the study, Echinococcus species are detected in adult pasture-raised sheep throughout the year, the invasion intensity and extensity average 22.3 ± 2.1 parasites/animal and 23.0%, respectively. It was found that echinococcosis was reported in adult sheep and goats in all the Caspian Sea region areas covered by the study. Complete helminthological necropsy revealed the presence of fertile larva cysts in 1 mL of echinococcal fluid in sheep and goats of all age groups, except for animals under 1 year of age; their number averaged 23.02 ± 1.28 larval cysts/animal. It is shown that echinococcosis is widely spread in carnivores and livestock across all altitudinal zones of the Caspian Sea region of Russia, including Dagestan, and this suggests the necessity of continuous epizootiological control and monitoring of the situation with respect to cestodes of the family Taeniidae, in particular Echinococcus granulosus. Since echinococcosis in dogs and other carnivores constitutes a large-scale social problem and is a helminthiasis that is dangerous for humans, seeking state-of-the-art ways and means to combat this parasitic disease of carnivores is an urgent challenge. Based on the results of the tests performed, the complex product Prazibars administered individually one time at a dose of 15.0 mg/kg of live weight in admixture with minced meat demonstrated high effectiveness against spontaneous echinococcosis in dogs and other carnivorous animals

Овощеводство Азербайджана в современных условиях

Relevance. Vegetable growing is a traditional sector of agriculture in Azerbaijan. The republic has all the conditions for its development, both natural and socio-economic. Materials and methods. The aim of the research was to analyze the current state of vegetable growing in the republic, to identify the strengths and weaknesses of the industry, to determine the terms of support for producers from the state and branch science. Results. The gross harvest of vegetables has been steadily growing in the last decades, and by 2019 amounted to 1715 thousand tons. The yield of vegetables also increased during this period from 14, 7 to 21.9 t / ha. In door production area is approximately 4800 ha. The production of greenhouse vegetables is focused on the Russian market. The bottleneck in the industry is vegetable seed production, a market with a capacity of almost 20 million euros is occupied by foreign companies. At the same time, the agricultural producers get state support in the form of subsidies and soft loans and a full tax exemption. Industry science is also developing: the Research Institute of Vegetable Production has been reconstructed and fully equipped, special training organized for vegetable growers in the Azerbaijan State Agrarian University. Further development of the industry continues through the intensification and biologization of production, expanding the range and improving product quality. Актуальность. Традиционной отраслью аграрного сектора Азербайджана является овощеводство. В республике имеются все условия для его развития, как природные, так и социально-экономические. Материалы и методы. Целью исследований явились анализ современного состояния овощеводства республики, выявить сильные и слабые стороны отрасли, определить степень поддержки производителей со стороны государства и отраслевой науки. Результаты. Валовый сбор овощей в последнее десятилетие наступательно растет и к 2019 году составил 1715 тыс. т. Урожайность овощей также вырос за этот период от 14, 7 до 21,9 т/га. Под овощи защищенного грунта занято 4800 га площади. Производство тепличных овощей ориентировано на российский рынок. Узким местом отрасли является овощное семеноводство, рынок емкостью почти 20 млн евро занят иностранными компаниями. В то же время с.-х. производитель пользуется поддержкой со стороны государства, в виде субсидий и льготного кредитования и полного освобождения от налогов. Развивается и отраслевая наука: реконструирован и полностью оснащен НИИ овощеводства, идет спецподготовка агрономов-овощеводов в Азербайджанском ГАУ. Дальнейшее развитие отрасли продолжается путем интенсификации и биологизации производства, расширения ассортимента и улучшения качества продукции.

Duality Invariant M-theory: Gauged supergravities and Scherk-Schwarz reductions

We consider the reduction of the duality invariant approach to M-theory by a U-duality group valued Scherk-Schwarz twist. The result is to produce potentials for gauged supergravities that are normally associated with non-geometric compactifications. The local symmetry reduces to gauge transformations with the gaugings exactly matching those of the embedding tensor approach to gauged supergravity. Importantly, this approach now includes a nontrivial dependence of the fields on the extra coordinates of the extended space.Comment: 22 pages Latex; v2: typos corrected and references adde

Abundance analysis of two late A-type stars HD 32115 and HD 37594

We have performed abundance analysis of two slowly rotating, late A-type stars, HD 32115 (HR 1613) and HD 37594 (HR 1940), based on obtained echelle spectra covering the spectral range 4000-9850 AAngstrom. These spectra allowed us to identify an extensive line list for 31 chemical elements, the most complete to date for A-type stars. Two approaches to abundance analysis were used, namely a ``manual'' (interactive) and a semi-automatic procedure for comparison of synthetic and observed spectra and equivalent widths. For some elements non-LTE (NLTE) calculations were carried out and the corresponding corrections have been applied. The abundance pattern of HD 32115 was found to be very close to the solar abundance pattern, and thus may be used as an abundance standard for chemical composition studies in middle and late A stars. Further, its H-alpha line profile shows no core-to-wing anomaly like that found for cool Ap stars and therefore also may be used as a standard in comparative studies of the atmospheric structures of cool, slowly rotating Ap stars. HD 37594 shows a metal deficiency at the level of -0.3 dex for most elements and triangle-like cores of spectral lines. This star most probably belongs to the Delta Scuti group.Comment: 10 pages, 4 figure
