It is a baby silicone mold comparative analysis of the characteristics of the vitamin status of schoolchildren during the summer recreation of 90th years of the last century and now.The study involved 167 schoolchildren aged 11-14 years.With the help of questionnaires developed by the authors assessed the severity of symptoms of vitamin deficiency,
The asymmetric design of hairpin windings is known as a method for reducing AC losses in electric motors, especially at high frequencies.However, the design of the asymmetric winding is very critical to obtaining the best benefit regarding the efficiency and the thermal performance of the motor.Compared to the state-of-the-art in this paper, deep i
1-(2-Hydroxyethyl)imidazolidine-2-thione (1) was obtained as a product from an in situ reaction between N-(2-hydroxyethyl)ethylenediamine, carbon disulfide, potassium hydroxide, and di(4-fluorobenzyl)tin dichloride.Compound 1 was characterized by IR, UV, 1H, 13C{1H}, and 2D (COSY, NOESY, HSQC, and HMBC) NMR spectroscopies.The cyclic rockfleece mole
Prestress in amorphous solids bears the memory of their formation and plays a profound role in their mechanical properties.Here we develop a set of mathematical tools to investigate mechanical response of prestressed systems, using stress rather than strain as the fundamental variable.This theory allows microscopic prestress to vary for the same sh
