Abstract: Предлагаемый электродвигатель предназначен для обеспечения вращения и содержит механизм преобразования поступательного движения во вращательное, кинематически связанный с валом двигателя и с двумя гофрированными цилиндрами, заполненными легкокипящей жидкостью, внутри которых размещены нагревательные и охлаждающие элементы. При прохождении тока в обоих направлениях в одном цилиндре жидкость нагревается, а в другом охлаждается и наоборот. В результате этого цилиндры, расширяясь и сокращаясь, совершают поступательное движение, которое преобразуется во вращательное движение вала электродвигателя, частота вращения которого может изменяться путем изменения частоты подводимого тока. Технический результат заключается в экономии меди и электротехнической стали. 1 з.п.ф-лы, 5 ил.

Abstract: Изобретение предназначено для оценки качества полиакриламидных гелей (ПААГ) и других биогелей, применяемых в экспериментальной вирусологии и пластической хирургии. Контроль цитотоксичности биогелей проводят с использованием штамма перевиваемых лейкоцитов человека Л-41-КД/84. Гель добавляют в среду роста тест-культуры. Доза посадки составляет 60 тыс. кл./мл. Культивируют в течение 72-96 ч. Далее определяют в динамике цитофизиологическую и цитоморфологическую стабильность культуры. При этом морфологическое исследование проводят по общепринятой методике. Определяют показатели эффективности прикрепления, полиферативной и митотической активности клеток, патологии митоза, морфологии клеток в монослое. Оценивают цитотоксичность биогелей по изменению этих показателей по сравнению с контролем. В качестве контроля используют такую же тест-культуру, но без внесения геля. Изобретение позволяет дифференцировать препараты биогелей по их цитотоксичности, что исключает возможность использования цитотоксичных и фальсифицированных материалов, а также предупреждает вредные последствия их воздействия на организм. Объективность и стандартность контроля качества препарата обеспечивает использование для оценки цитотоксичности стандартной тест-культуры штамма перевиваемых лейкоцитов человека Л-41-КД/84, обладающей стабильностью культуральных и морфологических свойств.
