Conceptual foundations of classes with the disciples of special medical group in secondary schools

Purpose: study and scientific rationale for new approaches to the organization of educational work with students of special medical group in secondary schools. Material : analyzed 15 scientific sources regarding the approaches of different authors to develop educational programs for students of special medical group. Results : focuses on the outstanding issues in a substantive, logistical and human aspects. Found that the selection of the content of educational material for special medical groups is an empirical question. Selection is carried out by copying the existing curriculum of physical culture for healthy children with an indication of the load reduction and exemption of complex elements. Established a complete absence of evaluation of educational achievements of pupils. Based on modern approaches to teaching students based on biomedical and didactic aspects: Leading defined function of each stage of training, fleshed main goals and objectives of the educational process, substantiated various kinds of sports activity, taking into account the diagnosis of diseases and the needs of students of different ages and gender. Conclusions : the main controversy in the decision of the designated problem. Substantiated leading features of each stage of training in special medical groups. A system of assessment of students' achievements

Artificial ionospheric layers driven by high-frequency radiowaves : an assessment

High-power ordinary mode radio waves produce artificial ionization in the F-region ionosphere at the European Incoherent Scatter (EISCAT at Tromsø, Norway) and High-frequency Active Auroral Research Program (HAARP at Gakona, Alaska, USA) facilities. We have summarized the features of the excited plasma turbulence and descending layers of freshly-ionized (“artificial”) plasma. The concept of an ionizing wavefront created by accelerated suprathermal electrons appears to be in accordance with the data. The strong Langmuir turbulence (SLT) regime is revealed by the specific spectral features of incoherent radar backscatter and stimulated electromagnetic emissions. Theory predicts that the SLT acceleration is facilitated in the presence of photoelectrons. This agrees with the intensified artificial plasma production and the greater speeds of descent but weaker incoherent radar backscatter in the sunlit ionosphere. Numerical investigation of propagation of O-mode waves and the development of SLT and descending layers have been performed. The greater extent of the SLT region at the magnetic zenith than at vertical appears to make magnetic zenith injections more efficient for electron acceleration and descending layers. At high powers, anomalous absorption is suppressed, leading to the Langmuir and upper hybrid processes during the whole heater-on period. The data suggest that parametric UH interactions mitigate anomalous absorption at heating frequencies far from electron gyroharmonics and also generate SLT in the upper hybrid layer. The persistence of artificial plasma at the terminal altitude depends on how close the heating frequency is to the local gyroharmonic

An algorithm development of a joint aerodynamic and mechanical speed control of the wind turbine

The article discusses non-electrical ways of ensuring the quality of electricity generated by wind power system. The algorithm of active aerodynamic control, which was established, based on the iteration in progress in rapidity. A method of determining gear ratio single-stage multiplier, which is used in conjunction with the position control of the blades, based on the calculation of lines of constant frequency. There are suggested some recommendations for the generalization to calculate the transmission and the varistor. Application of the developed algorithms is possible for research purposes in the modeling in Simulink of operation modes of the wind turbine with aerodynamic or joint aero-mechanical regulation of frequency and active power.В работе рассмотрены неэлектрические способы обеспечения качества электроэнергии, генерируемой ветроэнергетической установкой.

Даны рекомендации по её обобщению для расчета коробки передач и варистора. Применение разработанных алгоритмов возможно в исследовательских целях при моделировании в Simulink режимов работы ветроэнергетической установки с аэродинамическим или совместным аэро-механическим регулированием частоты и активной мощности
