    An algorithm for selection of the size of a correlation kernel at displacement vector field construction by the method of digital image correlation has been proposed. The algorithm has been tested on simulated and experimental optical images having different texture. The influence of the correlation kernel size and image texture on nose immunity at determining displacements has been studied. It is shown that the proposed algorithm allows to find this size providing the minimum error when determination of displacements and estimation of deformation

    Ежемесячно потребители в квартирах платят за электроприборы в соответствии с потребляемой ими энергией. Данная статья представляет собой описание первых шагов, направленных на развитие и оптимизацию режимов распространенных бытовых устройств, и, как результат, и на финансовые расходы потребителей. Прежде всего, электрические приборы были разделены на 3 группы в соответствии с их режимами работы. Холодильник как представитель группы приборов резко переменной нагрузки, был выбран для основных измерений. Измерение Показателей качества электроэнергии (ПКЭ) и снятие графиков нагрузки осуществлялось с помощью прибора регистратора-анализатора ПКЭ Chauvin Arnoux СА 8335+. Анализ кривых нагрузки и графика расхода средств позволяет рассчитать финансовые затраты в процентах. Эти исследования могут стать основой для дальнейшего исследования в области уменьшения и оптимизации расходов.In modern world each of us has a range of electric appliances, which simplified our daily life, in our house or flat. But what is more all of us are obligated to pay for work of all devices, which means for power they consume. This paper represented first steps aimed to develop and optimize modes of common household devices and as a result our financial expenses. At first all electric appliances were shared to 3 groups according with their modes. Then refrigerator, as a representor of abruptly variable load group, was chosen for main measurements. Measurement of Unified Power Quality Index (UPQI) and reading load curves were accomplished by means of the UPQI logger ChauvinArnouxСА 8335+. Provided load curves and flow chart of funds allow to calculate financial expenses in percent. This research formulates base for following investigation in field of consume and expense optimization

    In the article the complex therapy of varicose vein disease of pelvis minor in women is suggested; it includes phlebotropic, metabolic and immunotropic drugs. Indicated scheme of treatment lead to improvement of hemodynamic parameters of venous system of pelvis minor. Positive changes of parameters of cytokine, cellular and humoral units of immune system are evidence for decrease of inflammatory response of venous vascular wall

    Apoptosis in the liver of male <em>db/db</em> mice during the development of obesity and type 2 diabetes

    Get PDF
    Obesity and diabetes mellitus are known to lead to the development of metabolic syndrome and non-alcoholic fatty liver disease (NAFLD). The mechanisms of programmed cell death are actively involved in maintaining cellular homeostasis along development of NAFLD. Proteins of the BCL-2 family are key regulators of physiological and pathological apoptosis. Homozygous males of BKS.Cg-Dock7mLeprdb/+/+/J mice (db/db mice) are characterized by progressive obesity and the development of type 2 diabetes mellitus (DM2) with severe hyperglycemia at 4–8 weeks and organ lesions at 8–10 weeks of age. The aim of this research was to study the expression of molecular cell regulators of apoptosis in liver cells of db/db mice males at different stages of obesity and diabetes development (at the age of 10 and 18 weeks). Immunohistochemical analysis (using the indirect avidin-biotin peroxidase method) and morphometric evaluation of the expression of the antiapoptotic protein Bcl-2 and the proapoptotic protein Bad in liver cells of studied animals at different stages of obesity and DM2 were carried out. An excess of the value of the Bcl-2 protein staining area over the Bad protein staining area was revealed in the liver of 10-week-old animals. The Bcl-2/Bad expression area ratio in 10-week-old animals was twice as high as in 18-week-old animals, which indicates the presence of conditions for blocking apoptosis in the liver of younger db/db mice. At the 18th week of life, db/db mice displayed an almost threefold increase in the expression area of the Bad protein against the background of an unchanged expression of the Bcl-2 protein. The decrease in the Bcl-2/Bad staining area ratio in 18-week-old animals was due to the increase in the Bad expression area, which indicates the absence of antiapoptotic cell protection and creates conditions for activation of the mitochondrial pathway of apoptosis in the liver of male db/db mice with pronounced signs of obesity and DM2

    Although deep learning algorithms show increasing promise for disease diagnosis, their use with rapid diagnostic tests performed in the field has not been extensively tested. Here we use deep learning to classify images of rapid human immunodeficiency virus (HIV) tests acquired in rural South Africa. Using newly developed image capture protocols with the Samsung SM-P585 tablet, 60 fieldworkers routinely collected images of HIV lateral flow tests. From a library of 11,374 images, deep learning algorithms were trained to classify tests as positive or negative. A pilot field study of the algorithms deployed as a mobile application demonstrated high levels of sensitivity (97.8%) and specificity (100%) compared with traditional visual interpretation by humans-experienced nurses and newly trained community health worker staff-and reduced the number of false positives and false negatives. Our findings lay the foundations for a new paradigm of deep learning-enabled diagnostics in low- and middle-income countries, termed REASSURED diagnostics1, an acronym for real-time connectivity, ease of specimen collection, affordable, sensitive, specific, user-friendly, rapid, equipment-free and deliverable. Such diagnostics have the potential to provide a platform for workforce training, quality assurance, decision support and mobile connectivity to inform disease control strategies, strengthen healthcare system efficiency and improve patient outcomes and outbreak management in emerging infections
