To study the association between polymorphic genetic markers, tumor necrosis factors and their receptors (rs 1800629 TNFα, rs 909253 Ltα, rs 767455 TNFR1, rs 1061624 TNFR2) and the development of type 2 diabetes (T2D) among the population of the Central Black Earth Region of Russi

Investigation of the structure and microhardness of Mo-Fe-C coatings obtained by the electron beam injected in the atmosphere

In this work 'Mo-Fe-C' coatings fabricated on medium carbon steel by non-vacuum electron beam cladding were investigated. The structure of coatings and transition zones were studied by scanning electron microscopy (SEM). It was shown that an increase of Fe percentage in the cladding mixture led to a decrease of the eutectic volume fraction in the coating and was accompanied by the formation of the gradient structure between the coating and a substrate material. Measurements of microhardness in the cross section of samples revealed that the cladding of a 'Mo-C powder mixture contributed to a 4.5-fold increase of microhardness

Society and the state in the pandemic context

Based on the importance of an unprecedented new reality, the authors were tasked with studying and analyzing the problems of interaction between the State and society in the context of the pandemic and the introduction of state measures to prevent the spread of viral infection, which to a degree or another limit the rights and freedoms of a person and citize

Use of a neural network in creating a digital assistant for blind and visually impaired people

The experience of ongoing research in image processing clearly demonstrates the huge scope for the development of new neural networks that can help people in a wide range of tasks. The authors chose the direction of work related to helping people who have vision problems. The article considers a convolutional neural network of the Mask R-CNN model for segmenting objects in an image. During the research the authors study a large number of algorithms that can quickly and accurately process images, such as Faster R-CNN, which was the most efficient in 2020. During the analysis, it was revealed that the use of Mask R-N technology can significantly increase the efficiency of performing tasks, since this algorithm is the latest version of the machine learning model. As a result of the study, a neural network was developed that is capable of identifying and distinguishing a large number of objects in an image. The next step is to refine the algorithm and use additional means of interaction with the hardware of the systems to increase the speed of the neural network. In the future, the resulting neural network will be integrated into the Digital Assistant for the Blind and Visually Impaired Persons application. This application is guaranteed to improve the daily life of people with disabilities who experience certain inconveniences due to their features, and can become the basis for other, larger projects related, for example, to unmanned devices, as well as services whose work is directly based on image processing

Beta herpes viruses in patients with cutaneous graft-versus-host disease

Graft-versus-host disease is a major complication of allogenic bone marrow transplantation. Beta herpes viruses’ role in pathogenesis and prognosis of graft-versus-host disease is significant. Objective: To study beta herpes viruses evidence in skin biopsy specimens in graft-versus-host disease patients. Material and methods: Clinical features of 50 patients with cutaneous graft-versus-host disease were examined. Cytomegalovirus and human herpes virus 6 DNA detection in skin biopsy specimens was performed by PCR. Results: Correlation between human herpes virus 6 and poor prognosis in graft-versus-host disease patients has been found. Conclusion: Beta herpes virus detection after allogenic bone marrow transplantation could be important in prognosis of graft-versus-host disease

Space Weather and Its Impact on Psycho-Emotional State of the Inhabitants of Different Latitudes

Purpose of the research was to conduct a comparative analysis of the psychological characteristics of the inhabitants of the northern and middle latitudes, depending on their psychological sensitivity to changes in geomagnetic disturbances Materials and Methods: The study included 78 relatively healthy volunteers (women and men, the average age of 44.2[36.7; 54.3] years) living in the polar (Tiksi), subpolar (Yakutsk) and middle (Saratov) latitudes. Monitoring of the studied indicators was carried out during March and April 2016. To achieve this goal, the following methods were used: the Spielberger-Khanin scale for reactive (situational) and personal anxiety; E. Heim's technique for revealing individual coping strategies; the projective psycho-geometric test. Every day, during March and April 2016, the Kp-index, an integral indicator of changing geomagnetic disturbance was used. Depending on the identified matches, the peak values of the reactive anxiety by Spielberger-Khanin and Kp-index (not less than 60% of cases), all volunteers were divided into 2 groups. Group 1 included persons with similar overlap and, therefore, carriers of psychological sensitivity to changes in the action of heliogeomagnetic factors. Group 2 included persons without a specified sensitivity, (i.e., no coincidences). Results: In the course of the study, both coinciding and latitude-related differences in the psychological characteristics of different groups of volunteers were established. In the inhabitants of the polar and subpolar latitudes, especially in Group 1, the behavioral sphere was the most vulnerable (no constructive coping strategies). In addition, their changes in the emotional sphere contributed to the manifestation of aggressiveness and suppression of emotions against the background of general concentration, purposefulness and integrity of the individual. Regardless of the latitude of residence, volunteers, psychologically sensitive to changes in heliogeomagnetic factors, were more constructive in the emotional sphere, and the least in the behavioral, which gives reason to state that, depending on the factors of space weather, the behavior of the individual is the most vulnerable

Behavior and Impact of Zirconium in the Soil–Plant System: Plant Uptake and Phytotoxicity

Because of the large number of sites they pollute, toxic metals that contaminate terrestrial ecosystems are increasingly of environmental and sanitary concern (Uzu et al. 2010, 2011; Shahid et al. 2011a, b, 2012a). Among such metals is zirconium (Zr), which has the atomic number 40 and is a transition metal that resembles titanium in physical and chemical properties (Zaccone et al. 2008). Zr is widely used in many chemical industry processes and in nuclear reactors (Sandoval et al. 2011; Kamal et al. 2011), owing to its useful properties like hardness, corrosion-resistance and permeable to neutrons (Mushtaq 2012). Hence, the recent increased use of Zr by industry, and the occurrence of the Chernobyl and Fukashima catastrophe have enhanced environmental levels in soil and waters (Yirchenko and Agapkina 1993; Mosulishvili et al. 1994 ; Kruglov et al. 1996)
