Nonlinear Spin Dynamics in Ferromagnets with Electron-Nuclear Coupling

Nonlinear spin motion in ferromagnets is considered with nonlinearity due to three factors: (i) the sample is prepared in a strongly nonequilibrium state, so that evolution equations cannot be linearized as would be admissible for spin motion not too far from equilibrium, (ii) the system considered consists of interacting electron and nuclear spins coupled with each other via hyperfine forces, and (iii) the sample is inserted into a coil of a resonant electric circuit producing a resonator feedback field. Due to these nonlinearities, coherent motion of spins can develop, resulting in their ultrafast relaxation. A complete analysis of mechanisms triggering such a coherent motion is presented. This type of ultrafast coherent relaxation can be used for studying intrinsic properties of magnetic materials.Comment: 1 file, LaTex, 23 page

Pathologies found in patients with chronic heart failure with different fractions

This article presents the results of a study of patients with chronic heart failure with different ejection fractions of the left ventricle, a comparative analysis of two groups of patients with an ejection fraction of less than 50% and an ejection fraction of 50% or more on pathologies and other indicators studied in this work is performed.В данной статье приведены результаты исследования пациентов с хронической сердечной недостаточностью (ХСН) с разными фракциями выброса (ФВ) левого желудочка, произведен сравнительный анализ двух групп пациентов с фракцией выброса менее 50% и фракцией выброса 50% и более по патологиям и прочим показателям, исследуемым в данной работе

Coherent spin relaxation in molecular magnets

Numerical modelling of coherent spin relaxation in nanomagnets, formed by magnetic molecules of high spins, is accomplished. Such a coherent spin dynamics can be realized in the presence of a resonant electric circuit coupled to the magnet. Computer simulations for a system of a large number of interacting spins is an efficient tool for studying the microscopic properties of such systems. Coherent spin relaxation is an ultrafast process, with the relaxation time that can be an order shorter than the transverse spin dephasing time. The influence of different system parameters on the relaxation process is analysed. The role of the sample geometry on the spin relaxation is investigated.Comment: Latex file, 22 pages, 7 figure

Processing Information by Punctuated Spin Superradiance

The possibility of realizing the regime of punctuated spin superradiance is advanced. In this regime, the number of superradiant pulses and the temporal intervals between them can be regulated. This makes it feasible to compose a kind of the Morse Code alphabet and, hence, to develop a technique of processing information.Comment: 6 pages, Revtex, 3 figure

Features of clinic and management for tuberculosis of urinary organs and male’s genitalia

We have learned long-term results of treatment of 622 patients with first time detected different clinical forms of tuberculosis of urinary organs and male's genitalia (TUOMG). Our patients were from urology department of Ural Re-serch Institute of Phthisiopulmonology and from Tuberculosis dispensary #1 of Sverdlovskay oblast. Follow-up period was from 1985 to 2011. According to clinical, roentgenological changes in uro-genital organs and TUOMG-classification all patients were subdivided on 4 groups: kidney’s parenchyma tuberculosis, tuberculous papilitis, monocavernous tuberculosis and polycavernous tuberculosis. Isolated nephrotuberculosis was diagnosed in 37,8 % of patients, in 62,2% it was combination of ТВ processes (in 26,4% nephrotuberculosis was complicated with tuberculosis of ureter, in 19,8% with tuberculosis of urinary bladder, in 40,2% (from the number of men) was combined with tuberculosis of male’s genitalia. There was performed nephrectomies in 17,8% of cases, epididimectomies in 11,7% of cases. Previous anti ТВ therapy allows significantly decreased the frequency of specific complications. In 13% of cases it was possible to perform organ-sparing operations.Изучены отдаленные результаты лечения 622 впервые выявленных больных с различными клиническими формами туберкулеза мочевых и мужских половых органов (ТММПО). Больные находились на лечении в урологических отделениях ФГБУ «УНИИФ Министерства здравоохранения России» и СОГУЗ ПТД № 1 г. Свердловской области в период с 1985 по 2011 гг. Исходя из классификации ТММПО, все пациенты были разделены на 4 группы: туберкулез паренхимы почек, туберкулезный папиллит, монокавернозный и поликавернозный туберкулез почки. Изолированный нефротуберкулез выявлен у 37,8% больных, а в 62,2% - сочетание процессов (в 26,4% случаев туберкулез почки был осложнен туберкулезом мочеточника, в 19,8% - туберкулезом мочевого пузыря и в 40,2% (от числа мужчин) - сочетался с туберкулезом мужских половых органов). По поводу ТММПО в 17,8% случаев выполнялись органоуносящие операции — нефрзктомии, в 11,7% - зпидидимзктомии. Предшествующая туберкулостатическая терапия позволяла существенно снизить частоту послеоперационных специфических осложнений; в 13,0% случаев из общего количества выполненных хирургических пособий удалось выполнить органосохраняющие операци
