Synthesis and Identification of Zinc Oxide Nanoparticles as Precursor for Getting Zinc-Based Biologically Active Additives

Zinc oxide nanoparticles were synthesized in order to get biologically active additive for correction of zinc-deficiency states. Nanosized zinc oxide was derived by through condensation method from zinc acetate and lithium hydroxide dissolved in dehydrated alcohol. Resulted particles were examined through method of small-angle X-ray scattering. Measurement results confirm presence of nanoparticles with average size about 2 nm.

Медицинская реабилитация больных ишемической болезнью сердца после операции коронарного шунтирования по программе, основанной на расчете удельной мощности нагрузки

International audienceThe article shows that the construction of a comprehensive program of physical rehabilitation of patients with coronary artery disease after CABG operations, based on the specific power load can more accurately determine the mode of physical activity and exercise and, thus, more effectively carry out rehabilitation.В статье показано, что построение комплексной программы физической реабилитации больных ИБС после операций КШ на основе удельной мощности нагрузки позволяет более точно определять режим физической активности и тренировок и, таким образом, более эффективно проводить реабилитаци

Photovaractor performance for optically controlled microwave circuits

The photovaractor for optically controlled microwave circuits was designed and studied. The photovaractor module was fabricated as a planar p-i-n photodiode chip placed in a fibre optic matching receptacles. Study of C-V characteristics in the light illumination mode has shown that capacitance characteristics are strongly dependent on the light illumination power. These variations of the photovaractor diode capacitance are large enough to be used in optically controlled circuits such as oscillators, mixers and switchers
