В диффузионно-релаксационном режиме кристаллизации 50% двухкомпонентных металлических расплавов в модели переходной двухфазной зоны оценены термодинамические параметры, при которых возможно образование полностью разупорядоченной двухкомпонентной кристаллической фазы с простой кубической элементарной решеткой стехиометрического состава. Исследована область вблизи точки разупорядочения кристаллической фазы и установлен закон стремления параметра дальнего порядка к нулю при достижении критической температуры (переохлаждения) системы двухкомпонентный расплав-кристалл. Установлены кинетические особенности роста кристаллической фазы в точке разупорядочения. Установлен закон восстановления упорядоченной двухкомпонентной кристаллической фазы во времени. Оценены возможные значения времен релаксации при переходе из разупорядоченной двухкомпонентной кристаллической фазы с простой кубической элементарной ячейкой к полностью упорядоченной. Установлены кинетические особенности образования полностью упорядоченного двухкомпонентного кристалла. REFERENCES Sarkisov P. D., Baikov Yu. A., Meshalkin V. P.

Meat is one of the main food products, as it is an valuable source of proteins containing all the essential amino acids, some mineral products, primarily iron and zinc. Meat products are an obligatory component of the diet throughout the entire childhood. The results of the assessment on the role of meat in ensuring the health of children, as well as the impact of inadequate intake on cognitive and motor functions, bone condition, etc. are presented. The article presents data on the evaluation of the role of meat in the concept of food programming. Specialized baby food products have undeniable advantages in the nutrition of young children. Standards are established for this category of products, which include regulated requirements for raw meat, ingredients, product quality, labeling, packaging, transportation and storage. These requirements guarantee high quality products with great nutritional and biological value.
This article discusses the relevant aspects of prevention of functional gastrointestinal disorders (FGID) in children of the first year of life. The preventive role of psychological support for families and breastfeeding in the early stages after the child’s birth is emphasized. The issues of formula feeding, the influence of the composition of infant formulas on the intestinal microbiota and its functional activity, which relates to the development of FGID, are discussed separately. The features of the composition of goat milk formulas are considered in the aspect of its effect on the gastrointestinal function in infants. Key words: infants, breastfeeding, formula feeding, microbiota, goat milk formula
