Nonlinear dynamics of beta induced Alfv\'en eigenmode driven by energetic particles

Nonlinear saturation of beta induced Alfv\'en eigenmode, driven by slowing down energetic particles via transit resonance, is investigated by the nonlinear hybrid magnetohyrodynamic gyro-kinetic code (XHMGC). Saturation is characterized by frequency chirping and symmetry breaking between co- and counter-passing particles, which can be understood as the the evidence of resonance-detuning. The scaling of the saturation amplitude with the growth rate is also demonstrated to be consistent with radial resonance detuning due to the radial non-uniformity and mode structure

Criticality in a Vlasov-Poisson system - a fermionic universality class

A model Vlasov--Poisson system is simulated close the point of marginal stability, thus assuming only the wave-particle resonant interactions are responsible for saturation, and shown to obey the power--law scaling of a second-order phase transition. The set of critical exponents analogous to those of the Ising universality class is calculated and shown to obey the Widom and Rushbrooke scaling and Josephson's hyperscaling relations at the formal dimensionality $d=5$ below the critical point at nonzero order parameter. However, the two-point correlation function does not correspond to the propagator of Euclidean quantum field theory, which is the Gaussian model for the Ising universality class. Instead it corresponds to the propagator for the fermionic {\it vector} field and to the {\it upper critical dimensionality} $d_c=2$. This suggests criticality of collisionless Vlasov-Poisson systems as representative of the {\it universality class} of critical phenomena of {\it a fermionic} quantum field description.Comment: 10 pages, 6 figures, Submitted to Phys.

Competitive complex of machinery and technologies for the production of grain and feed

The current situation in agricultural production is challenging. During the last 2 decades, the agrarian production system has been deteriorating. It concerns crop rotations, moisture accumulation and moisture conservation technologies, ways of increasing soil fertility and growing environmentally friendly grain, reducing production costs and increasing product profitability. But there are forced late sowings and artificial “drought”. All this provides reasons to consider domestic breeding and seed production obsolete and to introduce the foreign analogue, which has planned negative impacts not only on quantitative, but also on qualitative safety. The article provides the solution to this major strategic problem. Under the research program of the Russian Academy of Agricultural Sciences, a highly competitive technology for the production of grain and fodder was developed on the basis of only domestic equipment that 2-5 times predominates over the best foreign analogues in functional indicators. It was confirmed by a number of state tests in 1990-2016 and approved by numerous meetings of the Scientific and Technical Council of the Ministry of Agriculture of the Russian Federation, RAS. The units of domestic tractors and functional machines that can compete with the best foreign counterparts have been developed

Successful Surgery of Severely Comorbid Cystic Pulmonary Hypoplasia

Background. Cystic pulmonary hypoplasia is a malformation of terminal bronchial tree as a cystic dilatation of various size at the level of subsegmental bronchi or bronchioles, which accounts for 60–80% of the overall malformation incidence.Materials and methods. We present a descriptive case of general clinical picture, diagnostic radiological examination and choosing a strategy for surgical diagnosis and treatment of cystic pulmonary hypoplasia. Patient K., 57 yo, was admitted to the Republican Clinical Tuberculosis Dispensary with fibroatelectasis of the right lung lower lobe and underlying subcompensated diabetes type II, inspected by a phthisiatrician, thoracic surgeon and referred for surgical treatment.Results and discussion. A careful history inspection and X­ray data in most cases suffice to successfully diagnose the congenital type of cystic pulmonary defects. Treatment in such patients is personalised, with preference towards surgical intervention. A correct diagnosis is usually conditioned by a detailed and careful examination of the lung morbid morphology during surgery.Conclusion. Modern instrumental methods, with multispiral computed tomography in particular, are key to correctly diagnose a malformation. Relevant case reports are of interest and importance to advance research into causative factors of the disease

Influence of antihypertensive therapy on a condition of intrarenal hemodynamic in patients with abdominal obesity

То investigate antihypertension therapy effect on intrarenal hemodynamic 120 patients with hypertension (at 50 % a MetS) are surveyed. It is established that using of an angiotensin receptors blocker together with calcium channel blocker is accompanied by reduction of a lipid profile aterogenity and decrease in an insulin resistance in patients with hypertension and MetS. We also found an improvement of intrarenal hemodynamic parameters irrespective of existence of an accompanying metabolic syndrome.С целью изучения внутрипочечной гемодинамики на фоне антигипертензивной терапии обследовано 120 больных с артериальной гипертензией (у 50% метаболический синдром). Установлено, что использование блокатора рецепторов ангиотензина с антагонистом кальция сопровождается уменьшением атерогенности липидного профиля и снижением инсулинорезистентности у больных АГ в сочетании с МС, а также улучшением параметров внутрипочечной гемодинамики независимо от наличия сопутствующего метаболического синдрома

Gender differences in depressive disorders, cognitive functions impairments and life quality in elderly patients with cardiovascular diseases

Aim.To describe gender features of depressive disorders, cognitive and mnestic function impairments, life quality characteristic in elderly patients passing in-hospital rehabilitation course. Materials and methods. We investigated 26 men (23,6%) and 84 women (76,4%) with ischemic heart disease aged from 75 to 91 years old, average age - 83,9+3,3. Results. In elderly patients with cardio-vascular diseases predemential cognitive impairment and mild dementia was found in 76% of men and 91 % of women. Life quality proved to be low, estimated by every scale used for psychic and physical evaluation. Higher life quality was associated with male gender and in-hospital rehabilitation program raised both physical and psychic components for 19,9+2,4% и 8,3+1,8% respectively. Conclusion. In elderly patients with cardiovascular diseases more prominent life quality disorders and cognitive impairments are found in female group. This is most likely due to higher level of arterial hypertension prevalence in women.Цель исследования: Охарактеризовать гендерные особенности депрессив-ных расстройств, нарушений когнитивно-мнестической функции, качества жизни у лиц старческого возраста и их динамику на фоне стационарного этапа реабилитации. Материалы и методы: Обследовано 26 мужчин (23,6%) и 84 женщины (76,4%) с ишемической болезнью сердца в возрасте от 75 лет до 91 года, средний возраст 83,9+3,3 года. Результаты: У лиц старческого возраста с заболеваниями сердечно-сосудистой системы преддементные когнитивные нарушения и деменция легкой степени выраженности регистрируется у 76% мужчин и 91% женщин. Качество жизни характеризуется низкими значениями по всем шкалам как психического, так и физического компонента, при этом высокие значения качества жизни ассоциируются с мужским полом, а проведенное стационарное лечение в рамках комплексной реабилитационной программы способствует увеличениюфизического и психического компонента качества жизни на 8,3+1,8% и 19,9+2,4%, соответственно. Заключение:Гендерные особенности качества жизни и когнитивных функций у лиц старческого возраста с заболеваниями сердечно-сосудистой системы характеризуются более выраженными нарушениями в группе женщин, что, скорее всего, ассоциировано с большей распространенностью повышенного артериального давления
