Comprehensive Disposal of Decommissioned Vehicles

The article concerns the final stage of the life cycle of vehicles (on the example of Russia). The purpose of the study is to develop an organizational scheme for the gradual creation of a unified system for the disposal of all types of vehicles that are out of service. The study included a legal, technical, and territorial analysis. For territorial analysis, statistical data were taken for the following types of transport: buses, trucks and cars. The result of the work is the division of recycling enterprises by recycling levels, namely, the use of classification A, B, C, D. Recycling centers organization is usually considered within the Federal districts, which will lead to the dispersion of recycling capacities throughout Russia. The Federal district will have a radical ring system of organizing recycling centers at different levels. The State should create a unified recycling system with the adoption of regulatory documents on the interaction of participants in the disposal of vehicles, it should involve commercial organizations in recycling activities in future. The prospects of the study suggest 3 options for the placement of warehouses and recycling centers for their effective operation and address the issue of recycling of highly specialized transport. © 2021 Elsevier B.V..

Magnetic phase diagram and first principles study of Pb3TeCo3V2O14

An antiferromagnetic ordering in Pb3TeCo3V2O14 takes place through formation of short range correlation regime with T* ~ 10.5 K and succession of second order phase transition at TN1 = 8.9 K and first order phase transition at TN2 = 6.3 K. An external magnetic field rapidly destroys magnetic structure at T < TN2 and influences the magnetic order at TN2 < T < TN1 resulting in complex magnetic phase diagram of Pb3TeCo3V2O14 as derived from magnetization and specific heat measurements. The first principles calculations indicate that in variance with layered crystal structure the magnetic subsystem of Pb3TeCo3V2O14 is quasi-one-dimensional and highly unusual consisting of weakly coupled triangular tubes.Comment: 12 pages, 10 figure

Biosensors Based on Micro-algae for Ecological Monitoring of the Aquatic Environment

This chapter is devoted to research possibilities of using micro-algae as sensor elements for biological sensors of aquatic pollutants. The characteristics of the fluorescence of micro-algae pigments caused by laser light, called laser-induced fluorescence (LIF), were used as informative parameters. It is shown that the functioning of biological sensors is determined by the consistency and concentration of micro-algal cells as well as their internal state, which depends on the temperature, illumination, and chemical composition of the water. The results indicate a significant dependence of the LIF intensities of micro-algae from exposure of heavy metal ions, temperature, and illumination. In text is demonstrated specificity of the reaction of various micro-algae, belonging to different phylum. This fact can be used for identify the phylum of micro-algae in situ, and for the creation the biosensors of ecological monitoring aquatic environment

Pathogenic characteristics of intracellular infection in chlamydiosis

This review analyzes scientific data and systematized information regarding microbiological aspects and pathogenesis of chlamydia infection. Chlamydia are obligate intracellular microorganisms that are sensitive to any human cells where energy parasitism is possible: various types of epithelium, fibrocytes, histiocytes, glial and muscle cells, squamous epithelium of the meninges and eyeball, neurons, monocytes, macrophages. Structure, chemical composition and enzymatic activity of Chlamydia closely resemble those in Gram-negative bacteria, as they retain their morphological identity throughout the life cycle, possess cell wall, ribosomes, DNA, RNA, biochemical elements of glycolysis, tissue respiration, peptose production being sensitive to some broad-spectrum antibiotics, and are able to vegetative form division. In recent decades, the pathogenesis and clinical symptoms of chlamydial lesions in the urogenital tract, nervous, cardiovascular, musculoskeletal and bronchopulmonary systems have been actively studied, and new approaches and treatment schemes for chlamydia-infected patients are still developing. Over many decades, Chlamydia infection has been an important and urgent problem, not only due to its high prevalence, but also because of high rate of complications negatively affecting populational health and related demographic parameters. Chlamydia causes multiple diseases resulting in chronization of inflammatory process in all human organs and systems, and affects reproduction of population. Mandatory statistical recording of chlamydiosis cases introduced as early as in 1994 in the Russian Federation does not reflect the actual incidence rate. A rise in number of inflammatory diseases of the upper respiratory tract caused by Chlamydia undoubtedly increases its etiological importance, but data regarding etiopathogenetic role of Chlamydia in ENT pathology are ambiguous and contradictory. Available publications describe a large range of variation in rate of detected Chlamydia due to poor awareness of doctors about the microbiological properties of chlamydia, pathogenetic and clinical features of clinical signs of this infection, and lack of common and clear understanding on the algorithms for identifying and treating chlamydiosis. Since the majority of chlamydia-associated nosological forms are asymptomatic, knowing pathogenetic features of related will allow to prevent the spread of the infection and reduce subsequent socio-economic consequences

Features of lipid metabolism in patients with coronary artery disease and coronary syndrome X

Изучены особенности липидного обмена и уровня лептина в группах пациентов с ишемической болезнью сердца на фоне начального атеросклероза и интактных коронарных артерий (коронарный синдром Х). Проанализированы лабораторные данные 365 пациентов, в том числе 148 больных с ишемической болезнью сердца и начальным атеросклерозом коронарных артерий, подтвержденным данными коронарной ангиографии, и 217 пациентов с ишемической болезнью сердца и интактными коронарными артериями (коронарный синдром Х). Уровень лептина был значимо ниже в группе коронарного синдрома Х, а уровень липопротеинов низкой плотности в исследуемых группах не отличался. Количество пациентов с рекомендованной терапией статинами было выше в группе пациентов с атероcклеротическими изменениями коронарных сосудов. Определена гетерогенность группы коронарного синдрома Х по признаку выраженной извитости коронарных артерий: дислипидемия значимо чаще встречалась в группе без извитости коронарных артерий.We have studied the features of lipid metabolism and leptin level in groups of patients with coronary artery disease on the background of primary atherosclerosis and intact coronary arteries (coronary syndrome X). Laboratory data of 365 patients with coronary artery disease, including 148 patients with initial coronary atherosclerosis, confirmed by angiographic data, and 217 patients with intact coronary arteries (coronary syndrome X) have been analyzed. Leptin level was significantly lower in the group with coronary syndrome X and low density lipoproteins level in the studied groups did not differ. The number of patients with the recommended statin therapy was higher in the group of patients with atherosclerotic changes of coronary vessels. Heterogeneity of coronary syndrome X group has been defined on the basis of the severe coronary artery tortuosity: dyslipidemia was significantly more frequent in the group without coronary artery tortuosity

ЭФФЕКТИВНОСТЬ ВНУТРЕННЕГО ГОСУДАРСТВЕННОГО ФИНАНСОВОГО КОНТРОЛЯ

The structural reform of the state financial control bodies brings forward the issues of assessing the control efficiency. Today, the mechanisms used to evaluate the efficiency of the financial control powers, as well as the notion of efficiency itself, are rather vague and subjective. The authors have classified and summarized the existing approaches to the assessment of the control efficiency and research findings in this sphere, identified the flaws and analyzed the reasons for poor applicability of the existing approaches in terms of current trends and problems of control activities. The generalization of existing quantitative and qualitative approaches to assessing the efficiency made it possible to classify the basic criteria that should be included in a potential model for evaluating the efficiency as well as develop additional factors that can have a significant impact on the control efficiency. The analysis of the actual performance of the state internal financial control authority and the inspections performed demonstrated the inapplicability of existing methods for assessing the efficiency of control activities. Proposals on the development of a radically new assessment model were made.В условиях реформирования структуры органов государственного финансового контроля особенно актуальными становятся вопросы оценки эффективности проводимых контрольных мероприятий. На сегодняшний день механизмы оценки эффективности реализации полномочий государственного финансового контроля, как и само понятие эффективности, достаточно расплывчаты и субъективны. Авторами структурированы и обобщены существующие подходы к оценке эффективности контрольной работы и проводимым научным исследованиям по их развитию, выявлены недостатки и проанализированы причины слабой применимости существующих подходов в условиях современных тенденций и проблематики контрольной деятельности. По результатам обобщения существующих качественных и количественных подходов к оценке эффективности проранжированы основные критерии, которые, по мнению авторов, необходимо включить в потенциальную модель оценки эффективности, а также разработаны дополнительные факторы, способные оказать существенное влияние на степень эффективности контрольной работы. На основании анализа фактических показателей результатов деятельности органа внутреннего государственного финансового контроля, а также направлений проводимых проверок продемонстрирована неприменимость существующих методов оценки эффективности контрольной работы и сформулированы предложения по формированию принципиально новой модели оценки эффективности
