The review is devoted to the study of brown adipose tissue in adults in the light of renewed scientific interest and the growing body of evidence that renewal and activation of this tissue can cause energy expenditure and play a significant role in the treatment of metabolic diseases in the future. Обзор посвящен изучению бурой жировой ткани у взрослых людей в свете обновленного научного интереса и растущего объема доказательств, что обновление и активация этой ткани может вызвать энергетический расход и в будущем играть значительную роль в лечении метаболических заболеваний. №1(65) (2019)

The article introduces modern approaches to catalyze energy efficiency efforts in Russia and Krasnodar region in particular – clean energy cluster concept and low-emission and climate-resilient development strategies (green LECRDS). The potential of Krasnodar region for developing clean energy and low-carbon sustainable development strategies were analyzed briefly. The key role of academic and research facilities in developing and applying of such innovative strategies was highlighted. Basic principles and methodological approaches of clean energy cluster formation in the framework of regional strategy of low-carbon sustainable development in Krasnodar region were proposed.

Based on above mentioned the authors set a goal to determine the bioavailabil-ity of meat in relation to its chemical composition depending on mono- and mixed infections in cattle. Studies are conducted on 20 animals that according to results of coprological research and helminthological autopsy by K.I. Skryabin method are divided into 4 test groups (5 heads in group). Animals in first group were infected with Fasciola sp., second group – Dicrocoelium sp., third group – association of Fasciola sp. and Dicrocoelium sp., fourth group – control group (intact group). Based on research results the authors came to conclusion that in case of trematodo-sis the changes of chemical composition and chemical physical properties of meat especially of beef registered by trematodosis may result in degeneration of quality and nutritional value of the most valuable food stuff. It is especially pointed out that the dry-substance content is reducing due to presence of mineral components. Moreover the protein fat ratio in helminthosis is less than the value of control group. This is especially expressed in dicrocoeliosis mono infection that may be caused by intoxication of animal and disturbance of proteins and fats metabolism. Infection with trematodes affect the chemical composition and reflect the nutrition-al value of meat that has been proven by reducing (Р < 0,001) of food energy by 52,49–66,47 kJ as well as by accumulating of products of decomposition of organic compounds verified by рН value and coefficient of acidity – oxidation of meat.

In this paper, we study the inverse problem for a mixed loaded equation with the Riemann-Liouville and Caputo operator in a rectangular domain. A criterion for the uniqueness and existence of a solution to the inverse problem is established. The solution of the problem is constructed in the form of the sum of a series of eigenfunctions of the corresponding one-dimensional spectral problem. It is proved that the unique solvability of the inverse problem substantially depends on the choice of the boundary of a rectangular region. An example is constructed in which the inverse problem with homogeneous conditions has a nontrivial solution. Estimates are obtained that allow substantiating the convergence of series in the class of regular solutions of this equation and the stability of the solution of the inverse problem from boundary data. В данной работе изучается обратная задача для смешанного нагруженного уравнения с оператором Римана-Лиувилля в прямоугольной области. Установлен критерий единственности. Построено решение задачи в виде суммы ряда по собственным функциям соответствующей одномерной спектральной задачи. Доказано, что однозначная разрешимость обратной задачи существенным образом зависит от выбора границы прямоугольной области. Построен пример, в котором обратная задача с однородными условиями имеет нетривиальное решение. Получены оценки, позволяющие обоснование сходимости рядов в классе регулярных решений данного уравнения и устойчивость решения обратной задачи от граничных данных. Вестник КРАУНЦ.

The aim of the research is to create innovative evaporating equipment that can produce concentrates with a high content of solids, with a low level of thermal effects on raw materials. The significance of the solution of technological problems of the key process of food technologies - concentration of liquid solutions (juices, extracts, etc.) is shown. Problems and scientific contradictions are formulated and the hypothesis on using of electromagnetic energy sources for direct energy transfer to solution’s moisture has been offered. The prospects of such an energy effect are proved by the energy management methods. The schemes of fuel energy conversion for the conventional thermal concentration technology and the innovative plant based on the electromagnetic energy generators are presented. By means of the similarity theory the obtained model is transformed to the criterial one depicted kinetic of evaporation process at the electromagnetic field action. The dimensionless capacity of the plant is expressed by the dependence between the Energetic effect number and relative moisture content. The scheme of automated experimental system for study of the evaporation process in the microwave field is shown. The experimental results of juice evaporation are presented. It has been demonstrated that the technologies of selective energy supply represent an effective tool for improvement of juice concentration evaporative plants. The main result of the research is design of the evaporator that allows reaching juice concentrates with °brix 95 at the temperature as low as 35°С, i.e. 2…3 times superior than traditional technologies.
