Symmetry Operators for the Fokker-Plank-Kolmogorov Equation with Nonlocal Quadratic Nonlinearity

The Cauchy problem for the Fokker-Plank-Kolmogorov equation with a nonlocal nonlinear drift term is reduced to a similar problem for the correspondent linear equation. The relation between symmetry operators of the linear and nonlinear Fokker-Plank-Kolmogorov equations is considered. Illustrative examples of the one-dimensional symmetry operators are presented

Water Circulation in the Northern Black Sea in Summer 2016 (Based on the Data Obtained in the 87th Cruise of the R/V Professor Vodyanitsky)

The present work represents the results of water circulation in the northern Black Sea analyzed based on the data of the surveys carried out in the 87th cruise of R/V Professor Vodyanitsky in July 2016. It is shown that during the survey the westward flows being the Rim Current (RC) manifestation are predominant within the studied water area. Based on the survey data, the latitudinal location of the Rim Current geostrophical deep stream is close to its climatic position. In the western part of the polygon, the Rim Current is divided into three branches. The northern branch is located over the shelf, the central one – over the continental slope and the southern one – over the deep-sea regions. The Sevastopol anticyclone is characterized by extremely asymmetric vertical development: its northern periphery over the shelf is weak, whereas the southern periphery over the continental slope is intensive. In the central part of the polygon the Rim Current intensifies, at that one intensive stream is traced. In the eastern part of the polygon two branches of the Rim Current are observed: the intensive northern one over the continental slope and the coastal shelf, and the one located closer to the deep-sea regions (its velocity is rather low and it weakens moving eastward). In the upper layer to the east off Cape Ai-Todor, the anticyclonic gyre is observed; whereas within the 50–100 m below it, the cyclonic turn of the currents is revealed

Research errors level gauges ultrasonic integrated by the method matrix

Виконано аналіз внутрішніх і зовнішніх факторів, котрі впливають на точність вимірювального контролю ультразвукових рівнемірів. Показано, що електрофізичні параметри викликають похибки вимірювального контролю для рівнемірів, які засновані на вимірюванні тривалості часу перенесення ультразвукового механічного імпульсу через газове середовище. Показано, що похибки рівнеміра розподіляються нелінійно як за діапазоном вимірювального контролю, так і за характером зміни впливового фактора. Досліджується метод інтегральної матриці для оцінки похибок ультразвукового рівнеміра.Выполнен анализ внутренних и внешних факторов, которые влияют на точность измерительного контроля ультразвуковых уровнемеров.

Current status of turbulent dynamo theory: From large-scale to small-scale dynamos

Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of the turbulence, power develops on large scales, which is not present in non-helical small-scale turbulent dynamos. At small length scales, differences occur in connection with the dissipation cutoff scales associated with the respective value of the magnetic Prandtl number. These differences are found to be independent of whether or not there is large-scale dynamo action. However, large-scale dynamos in homogeneous systems are shown to suffer from resistive slow-down even at intermediate length scales. The results from simulations are connected to mean field theory and its applications. Recent work on helicity fluxes to alleviate large-scale dynamo quenching, shear dynamos, nonlocal effects and magnetic structures from strong density stratification are highlighted. Several insights which arise from analytic considerations of small-scale dynamos are discussed.Comment: 36 pages, 11 figures, Spa. Sci.

Influence of transannular interaction over absorption and fluorescent properties of [2.2] paracyclophane and its phenyl derivatives

A significant bathochromic shift of the fluorescent and long-wavelength absorption bands of [2.2] paracyclophane comparing to corresponding bands of alkyl-benzenes is due to a strong transannular interaction, resulting in formation of a principally new excited state of lower energy. It is concluded that the fluorescent levels for alkylbenzene excimers and for the macrocycle are of the same nature. Analysis of [2.2] paracyclophane mono- and diphenylderivatives spectra shows that their intensive absorption bands (230–310 nm) are originated from electron transitions of biphenyl groups and weak long wavelength absorption (310–340 nm) and fluorescent bands are governed by the same electron transitions between ground and excimer-like excited states as in the case of non-substituted macrocycle
