Twists in U(sl(3)) and their quantizations

The solution of the Drinfeld equation corresponding to the full set of different carrier subalgebras in sl(3) are explicitly constructed. The obtained Hopf structures are studied. It is demonstrated that the presented twist deformations can be considered as limits of the corresponding quantum analogues (q-twists) defined for the q-quantized algebras.Comment: 31 pages, Latex 2e, to be published in Journ.

Intertwining technique for a system of difference Schroedinger equations and new exactly solvable multichannel potentials

The intertwining operator technique is applied to difference Schroedinger equations with operator-valued coefficients. It is shown that these equations appear naturally when a discrete basis is used for solving a multichannel Schroedinger equation. New families of exactly solvable multichannel Hamiltonians are found

PREVENTION OF ONCOLOGICAL DISEASES AS THE BASIS OF INTERACTION OF ONCOLOGICAL SERVICE WITH PRIMARY LINK OF HEALTH CARE

Malignant neoplasms (MN) are the second cause of death for the population of Russia, resulted in 15.5% of all deaths in 2015. Their share in the structure of the male population mortality rate was 16.4%, female — 14.4%. Among both sexes, deaths of working age, the proportion of deaths from MN was 16.0%, among women of reproductive age — 16.3%. More than half of the working age population of deaths in Russia falls on the disease from the group of preventable death, and a third — to preventable causes, depending on the primary and secondary prevention, quality of care, along with a high prevalence of behavioral risk factors (RF), demographic characteristics, marked medical and social reasons for the high mortality rate of the MN: late uptake of the population for health care, lack of alertness in oncology healthcare professionals, patients defects in routing.The leading factor in increasing life expectancy is prevention. Today, prevention is regarded as active method of strengthening and preservation of health, and the currently existing approaches in promoting healthy life mostly only directed at the prevention of behavioral risk factors: tobacco use, poor diet, physical inactivity and harmful use of alcohol. Experts estimate the impact on them will prevent, at least 40% of the cases of MN.In Russia we have a 3-step system of health care. In general preventive health orientation is implemented on the 1st level: in the provision of primary health care. In this regard, particular attention should be paid to the implementation of measures for specific clinical examination of the adult population, which plays an important role in the early detection of both the disease and the risk factors for their development. Properly organized conduct of the clinical examination can provide a substantial, up to 30%, the contribution to the reduction of total mortality, including mortality from MN. The necessity of increasing the role of the oncology service in the organizational and methodological support of the preventive measures implemented by primary health care is performed

On the Conundrum of the Heat Capacityof Metallic Nanoclasters

The heat capacity of nanoclusters was investigated using thermodynamics of surfaces, taking into account the surface enthalpy introduced by E. Guggenhein. It is shown that the cluster heat capacity Cp should be greater than the heat capacity C(b)p of the corresponding bulk phase. However, the (Cp - C(b)p)/ C(b)p  ratio should not exceed 50% up to very small clusters containing 100 atoms. Theoretical estimations agree with molecular dynamics results. So, experimental data on metallic nanoclusters and nanostructures demonstrating that Cp exceeds C(b)p in 2-5 times should be incorrect

PREDICTION BACKUP TESTICULAR FUNCTION IN PATIENTS WITH NONOBSTRUCTIVE AZOOSPERMIA

Modern authors believe that male infertility accounts for 40–50%. The most severe form of male infertility is azoospermia, which is observed in 10–15% of cases. The only method of diagnosis of azoospermia is testicular biopsy, which allows not only to differentiate the secretory and excretory forms of infertility, but also to determine the degree of impairment of spermatogenesis.Purpose. To improve the diagnosis of male infertility.Materials and methods. We have examined 26 men with non-obstructive azoospermia (according to semen). The comparison group included healthy men – 22 people. Patients underwent biopsy of the testicle, followed by morphological analysis of biopsies. Sections of testicular tissue was stained with hematoxylin and eosin, indirect immunohistochemical studies – definition of Inhibin B, a protein prolife ration and apoptosis (ki-67)Results. According to clinical and instrumental examination (ultrasound) we found no abnormalities. Patients set idiopathic form of infertility. When painting testice slices with hematoxylin and eosin, we recorded significant changes in the convoluted seminiferous tubules in patients with azoospermia: the diameter is reduced to 1.5–2 times (hypoplasia), the basement membrane with a strong fiber component (fibrosis) (p < 0,05). Expressed Inhibin tissue expression observed in Sertoli cells (“+++”) and to a lesser extent in spermatogonia ( «±»), located closer to the basal membrane convoluted seminiferous tubule. The expression level of Inhibin in germ cells - up to 5%. ki-67 protein expression was observed in the nuclei (S-phase of mitosis) spermatogonia (“++”) at stages II and III and spermatogenesis in some primary nuclei (“+”) and secondary (“+”) spermatocytes. Expression of ki-67 level in the germ cells – up to 25%.Conclusion. Determination of tissue levels of Inhibin-B can be used as a p rognostic test backup testicular function

Independent estimation of T\u3csup\u3e*\u3c/sup\u3e2 for water and fat for improved accuracy of fat quantification

Noninvasive biomarkers of intracellular accumulation of fat within the liver (hepatic steatosis) are urgently needed for detection and quantitative grading of nonalcoholic fatty liver disease, the most common cause of chronic liver disease in the United States. Accurate quantification of fat with MRI is challenging due the presence of several confounding factors, including T z.ast;2 decay. The specific purpose of this work is to quantify the impact of Tz.ast;2decay and develop a multiexponential Tz.ast;2 correction method for improved accuracy of fat quantification, relaxing assumptions made by previous T z.ast;2 correction methods. A modified Gauss-Newton algorithm is used to estimate the Tz.ast;2 for water and fat independently. Improved quantification of fat is demonstrated, with independent estimation of Tz.ast;2 for water and fat using phantom experiments. The tradeoffs in algorithm stability and accuracy between multiexponential and single exponential techniques are discussed. © 2010 Wiley-Liss, Inc

ВЛИЯНИЕ РАЗЛИЧНЫХ ВАРИАНТОВ ЛОПАСТЕЙ НЕСУЩЕГО ВИНТА НА Х-ОБРАЗНЫЙ РУЛЕВОЙ ВИНТ ВЕРТОЛЕТА

This paper describes the effect of different rotor blades on the X-shaped tail rotor of the Mi-171 LL, observed conducting flight tests. The tests were carried out on the same helicopter in the similar atmospheric conditions.The objective of the tests was the comparison of flight performance of two sets of rotor blades of the helicopter Mi-171 LL. However, materials test revealed a difference in the angles of the tail rotor at different MRs with the same takeoff weight.The authors are grateful to I.G. Peskov, S.R. Zamula and A.I. Orlov for assistance in carrying out this work and the preparation of this article.Noted that the helicopter takeoff weight when hovering out of ground effect in ISA with blades from polymer composite materials (PCM) exceeds the takeoff weight of the helicopter with the serial blades in the nominal mode of the engine operation at ~ 750kg, in the takeoff mode at ~ 700kg.Knowing the altitude and climatic characteristics of the engine, the obtained dependence allows to determine the balancing value of jрв on hovering at different combinations of pressure altitude and outside air temperature for a given speed of the main rotor (MR).It follows from the work that when the same value Nпр(95/nнвпр)3 or Nfact the balancing values of jрв for the helicopter with the main rotor blades from the PCM is less than for the helicopters with serial blades by 0.5…0.9°. The difference in the angles of the tail rotor increases with growing of Nепр(95/nнвпр)3 (Nfact). Perhaps this is caused by different induction effect of the main rotor on the tail rotor to the MR from PCM and the serial ones.As follows from the materials, the thrust of the main rotor with blades from PCM with the same engine power is more in comparison with the serial blades. Consequently inductive speeds of the main rotor are more and the angles of the tail rotor are less. It can be assumed that a large induced velocity of the main rotor increases the thrust of X-shaped tail rotor.В настоящей работе описывается влияние различных лопастей несущего винта на Х-образный рулевой винт вертолета Ми-171 ЛЛ, замеченное при проведении летных испытаний. Испытания проводились на одном и том же вертолете в близких атмосферных условиях.Задачей испытаний ставилось сравнение летно-технических характеристик двух комплектов лопастей несущего винта вертолета Ми-171 ЛЛ. Однако при обработке материалов испытаний было выявлено отличие в углах установки рулевого винта при различных несущих винтах с одинаковыми взлетными массами.Отмечено, что взлетная масса вертолета при висении вне влияния земли в условиях международной стандартной атмосферы с лопастями из композиционных материалов превышает взлетную массу вертолета с серийными лопастями на номинальном режиме работы двигателей на ~ 750 кг, на взлетном – на ~ 700 кг.Полученная в работе зависимость позволяет, зная высотно-климатические характеристики двигателя, определить балансировочное значение jрв на режиме висения при различных сочетаниях барометрической высоты и температуры наружного воздуха для заданных оборотов несущего винта.Из материалов работы следует, что при одном и том же значении Nпр (95/nнвпр)3 или Nфакт балансировочные значения jрв для вертолета с лопастями несущего винта из композиционных материалов меньше, чем для вертолета с серийными лопастями несущего винта на 0,5…0,9°. При этом разница в углах установки рулевого винта увеличивается с увеличением величины Nепр (95/nнвпр)3 (Nфакт). Возможно, это вызвано различным влиянием индукции от несущего винта на рулевой винт для лопастей несущего винта из композиционных материалов и серийных.Как следует из материалов, тяга несущего винта с лопастями несущего винта из композиционных материалов при одинаковой мощности двигателей больше, по сравнению с серийным, следовательно, больше индуктивные скорости от несущего винта. При этом углы установки рулевого винта меньше. Можно предположить, что большая индуктивная скорость от несущего винта увеличивает тягу Х-образного рулевого винта
