    In this work authors consider the integration processes in the former Soviet Union which allowed to create the economic and political organizations between the former federal republics. And also on the example of the Euroasian Economic Union positive tendencies in increase in economic capacity of the countries of participants are defined.В данной работе авторы рассматривают интеграционные процессы на постсоветском пространстве, позволившие создать экономические и политические организации между бывшими союзными республиками. А также на примере Евразийского Экономического Союза определяются положительные тенденции в увеличении экономического потенциала стран участниц

    Analytical model of brittle destruction based on hypothesis of scale similarity

    The size distribution of dust particles in nuclear fusion devices is close to the power function. A function of this kind can be the result of brittle destruction. From the similarity assumption it follows that the size distribution obeys the power law with the exponent between -4 and -1. The model of destruction has much in common with the fractal theory. The power exponent can be expressed in terms of the fractal dimension. Reasonable assumptions on the shape of fragments concretize the power exponent, and vice versa possible destruction laws can be inferred on the basis of measured size distributions.Comment: 10 pages, 3 figure

    FIELD: foundry.SUBSTANCE: method comprises steps of charging granular filler into mixer; at first charging one doze of filler and mixing it with binder till uniform distribution of binder on surface of grains of filler; adding second doze of filler and mixing it till uniform distribution of filler in the whole mass of molding sand. Invention provides shortened time period of distributing binder on surface of filler grains.EFFECT: enhanced strength of molding sand without increased consumption of binder.1 ex.Изобретение относится к литейному производству. Зернистый наполнитель загружают в смеситель по частям. Первую часть смешивают со связующим до равномерного распределения его по поверхности зерен наполнителя. Добавляют вторую часть наполнителя и перемешивают до равномерного распределения наполнителя в общей массе смеси. Снижается время распределения связующего по поверхности зерен наполнителя. Обеспечивается повышение прочности смеси без увеличения расхода связующего

    AUTOIMMUNE ORIGIN OF SARCOIDOSIS: DETERMINATION OF SPECIFIC IMMUNE COMPLEXES IN PATIENTS WITH RESPIRATORY SARCOIDOSIS

    The etiology of sarcoidosis is not completely understood. A hypothesis exists about the relationship between sarcoidosis and a complex of pathological autoimmune reactions that occur under the influence of triggering factors. In this study, specific immune complexes in the blood plasma of patients have been determined, which can indirectly reveal the causes of the disease.The study included 33 patients with lung sarcoidosis (I group), compared to 24 healthy donors who served as a control group (II group). The patients underwent standard examination. Their blood plasma was investigated by the dynamic light scattering method with addition of tuberculosis antigens (ESAT-6/SFP-10) and “lung healthy tissue extract”. Statistical analysis was performed using the Statistica 7.0 program. Test results were considered significant at p < 0.05.Аccording to the data obtained, addition of ESAT-6/SFP-10 to patient’s blood plasma almost did not lead to the formation of immune complexes in most samples. Meanwhile, development of such complexes after addition of “lung tissue extract” was revealed in all the patients. The immune complexes were not detected in any donor from control group after stimulation with both kinds of antigens (p < 0.01).The data on distinct formation of immune complexes with the addition of “lung healthy tissue extract” in patients with lung sarcoidosis may be considered an indirect evidence for occurrence of autoimmune reaction under the influence of some pathogenic factors. Absence of de novo immune complex formation after addition of tuberculosis antigens (ESAT-6/SFP-10) makes it unlikely any direct effects of tuberculosis bacteria upon development of sarcoidosis
