The article discusses the special aspects of healthcare in the Tula region in the second half of the 19th century. The author notes that a special social environment formed during this period in Tula, which was favorable for the activities of people thinking on a large scale. Key moments from regional healthcare development are presented using the example of one of the prominent representatives of Tula medicine from the late 19th century - V.I. Smidovich. His role is recognized in the organization of the medical research field - the founding and work of the Tula Physicians Society, and the creation of a free outpatients clinic to provide medical care to the poor. Particular attention is paid to Smidovich’s participation in the Congress of Zemstvo Doctors in Tula Province. Emphasis is placed on the establishment of statistics for the region, the main practical purpose of which was to study the population’s economic and living conditions (birth rate, mortality and morbidity). A number of Smidovich’s works on the public health and economic status of Tula are examined. The public’s state of health and its dependence on living conditions (environmental factors and the individual features of professional activities) is stressed in their importance for the health of the Tula province. On the basis of Smidovich’s fundamental works, as well as his activities with the Tula Physicians Society, the author draws a conclusion about his impact on the world view of one of his sons - doctor and author V.V. Smidovich (Veresaev), a landmark figure in the history of bioethics. It is noted that the ideas of Smidovich are reflected in the works of Veresaev. © Olga V. Tereshkina.

A simple model of electrochemical growth of nanowires in the pores of anodic aluminum oxide (AAO) template is developed. The metal deposition is considered at various overpotentials. The model takes into consideration the ionic transfer both in the varying diffusion layer in the pores and in the diffusion layer above the template, which is determined by the external hydrodynamic conditions. The model takes into account the kinetics of electrochemical reaction by means of the Tafel equation and the diffusion transfer of metal cations both in the pores and in the outer diffusion layer. The analytical solution of the problem with several simplifications yields the equations for calculating the time dependence of current, the pore filling time, and other parameters of the process. An example of the application of the model for the analysis of nanowire growth in the template pores is compared with the experimental data showing good agreement. © 2013 Elsevier Ltd.

Flavonoids are polyphenolic compounds produced by plants and delivered to the human body through food. Although the epidemiological analyses of large human populations did not reveal a simple correlation between flavonoid consumption and health, laboratory investigations and clinical trials clearly demonstrate the effectiveness of flavonoids in the prevention of cardiovascular, carcinogenic, neurodegenerative and immune diseases, as well as other diseases. At present, the abilities of flavonoids in the regulation of cell metabolism, gene expression, and protection against oxidative stress are well-known, although certain biophysical aspects of their functioning are not yet clear. Most flavonoids are poorly soluble in water and, similar to lipophilic compounds, have a tendency to accumulate in biological membranes, particularly in lipid rafts, where they can interact with different receptors and signal transducers and influence their functioning through modulation of the lipid-phase behavior. In this study, we discuss the enhancement in the lipophilicity and antioxidative activity of flavonoids after their complexation with transient metal cations. We hypothesize that flavonoid-metal complexes are involved in the formation of molecular assemblies due to the facilitation of membrane adhesion and fusion, protein-protein and protein-membrane binding, and other processes responsible for the regulation of cell metabolism and protection against environmental hazards. © 2014 Elsevier B.V.

In the course of development of navigation systems for small-sized highly maneuverable vehicles their sensors should be subjected to mechanical tests, because the sensor certificates usually omit information on their mechanical resistance. The paper presents the main results from Russian IMU AIST-350T mechanical tests: shock tests, sinusoidal and broadband random vibration. © 2014, Pleiades Publishing, Ltd.

The article considers results of empirical research which purpose was to study the future teachers’ ecological consciousness in the ascertaining stage of experiment. Analysis of the results was carried out on a number of criteria: motivational, cognitive, and emotional. The orientation of the future teachers on the educational and disciplinary or personal model of interaction with schoolchildren is regarded as the main indicator of ecological consciousness on motivational criterion. An indicator of cognitive criterion is knowledge about student’s personality as a biopsychosocial subject and laws of its development. Emotional criterion is studied by identifying the level of empathy and prevailing empathy channels. Standardized psychological techniques meeting the requirements for necessary quality indicators of tests are used for the diagnosis of each of the criteria: for motivational one - test-questionnaire by V. G. Maralova "Diagnosis of teachers’ orientation on disciplinary training or personal model of interaction with children" for cognitive one-test-questionnaire "Studying of I-Concept as justification of the influence on another person" (by A. G. Abramova); for emotional one - technique for diagnosing the level of empathic abilities of V. V. Boyko. Manifestations of ecological consciousness in action (behaviour) of the future teachers are traced by monitoring the system used by students during internship of professional activities and skills that reflect the particular model of the interaction with the students. Two learning groups of junior undergraduates make up the study sample. The obtained results allow to state that 1/3 of surveyed have a low level of environmental compatibility of pedagogical consciousness, half of the respondents - an average one and the remaining part - above average level. The lack of significant differences in the studied parameters between the experimental and control groups was revealed using the Student’s t-test and Wilcoxon - Mann - Whitney U-test. Based on the results obtained in the course of ascertaining stage, the conclusion about the necessity of a special work performance to improve the level of future teachers’ ecological consciousness development was made. © 2016, Springer New York LLC.

Face detection (FD) is widely used in interactive user interfaces, in advertising industry, entertainment services, video coding, is necessary first stage for all face recognition systems, etc. However, the last practical and independent comparisons of FD algorithms were made by Hjelmas et al. and by Yang et al. in 2001. The aim of this work is to propose parameters of FD algorithms quality evaluation and methodology of their objective comparison, and to show the current state of the art in face detection. The main idea is routine test of the FD algorithm in the labeled image datasets. Faces are represented by coordinates of the centers of the eyes in these datasets. For algorithms, representing detected faces by rectangles, the statistical model of eyes' coordinates estimation was proposed. In this work the seven face detection algorithms were tested; article contains the results of their comparison. © Springer-Verlag Berlin Heidelberg 2010.
