Analytical eighth-order light-by-light QED contributions from leptons with heavier masses to the anomalous magnetic moment of electron

The important consequences of the recent results of the numerical evaluations of eighth and tenth order QED contributions to the anomalous magnetic moment of electron are commented. The correctness of the results of the numerical evaluation of new eighth order QED corrections to the electron anomaly are supported by the demonstration of their consistency with the new analytical expressions for the QED contributions to $a_e$ from the diagrams with fourth-order light-by-light scattering muon and tau-lepton loops. The consistency of the similar results are demonstrated in the case of eighth order massive dependent contribution to the muon anomalous magnetic moment.Comment: 6 pages, LaTeX, The preliminary version of the longer work with the same title was registered as CERN Preprint during the visit to Theory Division of CERN in January of 201

On invariance of specific mass increment in the case of non-equilibrium growth

It is the first time invariance of specific mass increments of crystalline structures that co-exist in the case of non-equilibrium growth is grounded using the maximum entropy production principle. Based on the hypothesis of the existence of a universal growth equation, with the use of dimensional analysis, an explicit form of the dependence of specific mass increment on time is proposed. Applicability of the obtained results for describing growth in animate nature is discussed.Comment: 5 page

Numerical investigation of cavitating flow through the cascade of arbitrary foil

Two methods are considered for computer modeling of cavitating flow through a cascade of any foils. The first method consists of numerical modeling of non-circulation flows of a cascade of foils with subsequent analytical solution of platecascades. The second method provides direct computer modeling using numerical algorithms for an isolated foil. It is shown, that both methods yield identical numerical results but the second one is more convenient for numerical algorithms and computing.http://deepblue.lib.umich.edu/bitstream/2027.42/84321/1/CAV2009-final151.pd

Pumping or Mixing System Using a Levitating Magnetic Element

A system capable of pumping or mixing relatively warm fluids using a rotating magnetic element or bearing levitated by a cold superconducting element is disclosed. The magnetic element or bearing carries at least one impeller and is placed in a fluid vessel positioned external to the outer wall of a cryostat or other housing for the superconducting element. A separate cooling source thermally linked to the superconducting element provides the necessary cooling to create the desired superconductive effects and induce levitation in the magnetic element or bearing. The outer wall or housing defines a chamber around the cold superconducting element that thermally isolates it from the vessel. To ensure that the desired level of thermal isolation is provided, this chamber is evacuated or filled with an insulating material. This thermal isolation allows for placement of the superconducting element in close proximity to the wall or housing adjacent to the vessel to achieve a significant reduction in the separation distance from the magnetic element or bearing. This enhances the magnetic stiffness and loading capacity of the levitating element or bearing. However, since the superconducting element is thermally isolated from the outer wall or housing, the vessel, and hence the magnetic element/bearing and fluid contained therein, are not exposed to the cold temperatures required to produce the desired superconductive effects and the resultant levitation. By using means external to the vessel to rotate and/or stabilize the magnetic element/bearing levitating in the fluid, the desired pumping or mixing action is provided

Electromagnetic Cleaning of Household Waste Filtrate

Стаття присвячена фізичному методу очищення стічних вод побутових відходів. Для очищення потоку рідини використовується соленоїдний блок управління. Зниження агресивності фільтрату забезпечено видаленням домішок з основного потоку. З урахуванням властивостей матриці планування експерименту обчислені коефіцієнти регресійного рівняння. Вони адекватно відображають процеси управління траєкторією очищення рідини при її виведенні з основного потоку.The article is devoted to the physical method of wastewater treatment from household waste. A solenoid control unit is used to clean the fluid flow. Reducing the aggressiveness of the filtrate is provided by the removal of impurities from the mainstream. Taking into account the properties of the experiment planning matrix, the coefficients of the regression equation are calculated. They adequately reflect the processes of controlling the trajectory of cleaning the liquid when it is removed from the mainstream
