Диалектика и риторика испанского гуманиста Франсиско Санчеса ле лас Бросаса
In the preface to translating fragments from F. S. de las Brosas’s compositions we will examine the principal his logical, dialectical and rhetorical ideas. We also consider the infl uence of Aristotle’s theory on Spanish philosophy and logic.В предисловии к переводу отрывков из сочинений Ф. С. де лас Бросаса мы рассмотрим основные понятия его логики, диалектики и риторики. Также мы исследуем, каким образом логическая теория Аристотеля повлияла на развитие философии и логики в Испании
The features of real nutrition of preschool children in conditions of industrially polluted territories
An integral part of industrialized areas is the constant increase of technogenic influence on the human body. This contributes to the deterioration of health of the population and, above all, of children as the most sensitive contingent. The industrial district of the Dnipro city, which is characterized by intense pollution of the environment, is selected for research. It should be emphasized that the residential area is located near the territory of the sanitary-protected zone of manufacturing enterprises. The particular attention was paid to selection of the control area. Since it is practically impossible to find an area that is homogeneous by parameters, but not technogenically polluted in an industrial city - the conventionally "pure" rural area, located in the recreation area, has been chosen as a control one.
The purpose of the work was to give a hygienic assessment of the actual nutrition of children living in an industrially contaminated area, compared with the actual nutrition of kids in areas where there are no powerful industrial enterprises, in order to determine the compliance of food with current norms of physical needs of this contingent. Assessment of nutrition of children of preschool age was carried out in kindergartens using 10-day menu-schedules, the analysis of which indicates their non-compliance with hygiene requirements.
The received data testifies that the actual daily nutrition in kindergartens is scarce primarily with the number of biologically important products for the growing organism of the child: of animal origin - meat, fish up to 50%, dairy products from 25-26% to 85%, as well depleted amount of fruits and vegetables as sources of vitamins, trace elements and food fibers up to 71% with excessive consumption of cereals, pasta, sugar and sweets.
It should be added that the actual nutrition of children in the industrial region is imperfect and unbalanced by all major macro- and micro-nutrients with the insufficiency of the proteins, which in turn enhances the toxic effects of anthropogenic pollutants, reduces the organism's response to adverse environmental factors, potentiates the risk of health problems and causes the need to adjust their nutrition.
Thus, the obtained results show the necessity of continuing the comprehensive hygienic researches in this direction and are the scientific basis for studying the food supplement of the population, including children, as the most vulnerable part of the population to environmental factors, of other industrialized regions of the Dnipro and other powerful industrial regions as well as are the scientific basis for the search and implementation of effective remedies for its correction
Right to the city: Youth's view to live in the city
The article represents possibilities and problems of realization of the right to the city of youth in Yekaterinburg. According to the H. Lefebvre' concept,the article states that the next generation is aimed at appropriation of surrounding environment through changing it. By using questionnaires,there were 750 students and working youth interrogated,as well as there were 25 standard interviews with young citizens. The research results showed that young people mostly prefer cultural or recreational usage of urban spaces during the stability period. Youth as an active and dynamic social community acts as a carrier of protest sentiments. These moods become actual in cases of realizations of any administrative decisions directed to privatization of public spaces or affecting the interests of young generation. Materials suggest that the period of transition from consumption to appropriation and changing of urban spaces is observed. The Do-It-Yourself movement is becoming the instrument of Transition. © Published under licence by IOP Publishing Ltd.The reported study was funded by RFBR and Sverdlovsk region, project number 20-411-660012
Development of Cloud-Based Microservices to Decision Support System
Intelligent systems of simulation become a key stage of the scheduling of companies and industries work. Most of the existing decision support systems are desktop software. Today there is a need to use durability, flexibility, availability and crossplatforming information technologies. The paper proposes the idea of working cloud based decision support system BPsim.Web and this one consists of some set of services and tools. The model of the multiagent resources conversion process is considered. The process of the simulation model developing via BPsim.Web is described. An example of the real process model is given. © 2020, IFIP International Federation for Information Processing.Russian Foundation for Basic Research, RFBR: 18-37-00183The reported study was funded by RFBR according to the research project № 18-37-00183
Особливості візуальної метафорики в дизайні рекламних кампаній на екологічну тематику
Статтю присвячено розгляду особливостей використання візуальної метафорики в дизайні
соціальної реклами на екологічну тематику закордонних рекламних кампаній. Проаналізовано
специфіку зображально-виражальних засобів реклами проти винищення лісових ресурсів, виокремлено типові види візуальних метафор, використаних у рекламних матеріалах кампаній WWF
та інших світових громадських організацій на цю тему. З’ясовано, що основним елементом-реалізатором комунікативної стратегії авторів у рекламних матеріалах є зображальна частина
реклами, яка ґрунтується на метафоричному осмисленні дійсності, а текст слугує пояснювальним доповненням до неї. Візуальний контент може бути значною мірою відвертим, жорстоким,
апелювати до почуття провини й страху, що забезпечує впливогенність рекламних продуктів
та є фактором ефективності рекламної кампанії, яка стосується зазначеної проблеми.The article is dedicated to the peculiarities of visual metaphors usage in the design of foreign public
service announcement campaigns about ecological problems. The specifics of graphic and expressive
means of public service announcements against the destruction of forest resources is analysed, typical
types of visual metaphors used in public service announcement materials in campaigns of WWF and other
world public organizations about this topic are distinguished. It was found that the main implementation
element of authors’ communicative strategy in public service announcement materials is the graphic
part of advertising, which is based on a metaphorical understanding of reality, and the text serves as an
explanatory addition to it. Visual content can be largely outspoken, cruel, and appealing to guilt and fear,
which ensures the impact of suggestive influence of public service announcement products and serves as
a factor of effectiveness for a public service announcement campaign about this problem
Evaluation of the elastic properties and topography of leukocytes’ surface in patients with type 2 diabetes mellitus using atomic force microscope
The aim of study was to examine some morphometrical parameters (height, diameter) of the leukocytes (white blood cells - WBCs), their specific surface morphology (globular prominences and depression in WBCs) as well as their local elastic properties (Young’s modulus) in healthy persons and in patients with type 2 diabetes mellitus (T2DM) by means of the atomic force microscopy (AFM). Morphological and morphometrical parameters of human leukocytes were evaluated by AFM in tapped mod
Can ionic concentration changes due to mechanical deformation be responsible for the neurostimulation caused by focused ultrasound? a simulation study
Objective Ultrasound stimulation is an emerging neuromodulation technique, for which the exact mechanism of action is still unknown. Despite the number of hypotheses such as mechanosensitive ion channels and intermembrane cavitation, they fail to explain all of the observed experimental effects. Here we are investigating the ionic concentration change as a prime mechanism for the neurostimulation by the ultrasound. Approach We derive the direct analytical relationship between the mechanical deformations in the tissue and the electric boundary conditions for the cable theory equations and solve them for two types of neuronal axon models: Hodgkin-Huxley and C-fibre. We detect the activation thresholds for a variety of ultrasound stimulation cases including continuous and pulsed ultrasound and estimate the mechanical deformations required for reaching the thresholds and generating action potentials. Main results We note that the proposed mechanism strongly depends on the mechanical properties of the neural tissues, which at the moment cannot be located in literature with the required certainty. We conclude that given certain common linear assumptions, this mechanism alone cannot cause significant effects and be responsible for neurostimulation. However, we also conclude that if the lower estimation of mechanical properties of neural tissues in literature is true, or if the normal cavitation occurs during the ultrasound stimulation, the proposed mechanism can be a prime cause for the generation of action potentials. Significance The approach allows prediction and modelling of most observed experimental effects, including the probabilistic ones, without the need for any extra physical effects or additional parameters
