Morphology and properties of ZnO films obtained by repeated spin coating on porous silicon substrates

Layers of porous silicon (PS), multilayered ZnO films, and heterostructures based on them are obtained. The surface morphology, chemical and phase composition of the PS layers and ZnO films, and the transverse cleavage of ZnO-PS nanocomposite, are investigated via energy-dispersive X-ray spectral analysis (EDX), X-ray diffraction (XRD), and scanning electron microscopy (SEM

ПРОТЕИНОВАЯ И АМИНОКИСЛОТНАЯ ПИТАТЕЛЬНОСТЬ КОРМОВ ДЛЯ СВИНЕЙ

In pig fodder the algorithm of calculation of the presence of an "ideal" protein is developed on the basis of the data on the norms of the essential amino acids content in complete fodder and their content in basic fodder. The interrelation of the first limiting amino acid with the required norm makes an amount of complete sets of an "ideal" protein in fodder. Fodder ranging with reference to the content of an “ideal” protein and its cost has been conducted.Разработан алгоритм расчета наличия «идеального» протеина в кормах для свиней на основе данных по нормам содержания незаменимых аминокислот в полнорационных комбикормах и их содержания в основных кормах. Соотношение первой лимитирующей аминокислоты с нормой потребности составляет число комплектов «идеального» протеина в корме. Проведено ранжирование кормов по содержанию в них «идеального» протеина и его стоимости
