Controlled focusing of silver nanoparticles beam to form the microstructures on substrates

The aerodynamic focusing in the coaxial nozzle and deposition on substrates of silver nanoparticles beams at the high subsonic speeds has been studied. The multi-spark discharge generator was used as a source of silver nanoparticles. We established that controlling the high-speed sheath flow allows to provide the minimization of the aerosol beam diameter for 4 times and printing of silver lines with width up to 60 μm using a nozzle 100 μm in outlet diameter. It was realized due to usage of high-speed beams of silver nanoparticle agglomerates, with the size of 25–110 nm, consisting of the primary particles with diameter of 5–10 nm. The agglomeration effect of aerosol nanoparticles plays a positive role providing particle deposition onto a substrate and substantially reducing diffusion broadening of an aerosol beam

Implementation of Imitation Hypoxic Workout when Training Highly Qualified Downhill Skiers Based on Physical Exercise Individualization

В работе приводятся итоги экспериментального исследования, направленного на выяснение вопроса о возможности применения в подготовке лыжников-гонщиков высокой квалификации искусственной гипоксической тренировки (ИГТ), которая в сочетании с общепринятыми средствами спортивной тренировки обеспечивает высокий уровень достижений в отдельных видах спорта. В публикации представлены показатели физической нагрузки в микро- и мезоциклах подготовительного периода, а также направленность и содержание разработанной авторами методики развития специальной физической подготовленности высококвалифицированных лыжников-гонщиков при использовании различных средств и методов искусственной гипоксической тренировки. Доказана эффективность экспериментальной методики в повышении уровня физической подготовленности, функционального резерва организма спортсменов и результативности их соревновательной . This article presents the results of research on the expediency of imitation hypoxic workout when training highly qualified downhill skiers. This method, along with some other sports training methods, provides for impressive results in certain kinds of sport. This paper shows the indicators of physical exercise in micro and mesocycle of pre-season, as well as the material on the expediency of imitation hypoxic workout when training highly qualified downhill skiers. The effectiveness of experimental methods in increasing physical fitness as well as “the functional reservoir” of sportsmen’s bodies and their competitiveness has been proved
