Cartographic Analysis of the Radon Situation in the Environment

According to UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiations), no less than 10% of lung cancer diseases registered annually are caused by radon radiation. Born in the belly of the earth, the same gas, a class I cancirogen, increases the risk of non-cancerous diseases of the upper respiratory tract and cardiovascular diseases. The radon problem occupies an important place in the radioecological programs of the USA, Japan, Western Europe and Russia. However, the natural radiation varies in the background from location to location. In many countries, survey work is being carried out, including an assessment of the intensity of the radon hazards of sites allocated for construction. In Russia, the Radiation Safety Standards are stipulating that the concentration of radon in the air of residential premises should not exceed 200 Bq/m3; in Sweden, the maximum radon concentration is taken as 100 Bq/m3, in Finland and Canada - 400 Bq/m3, and in Germany and Great Britain - 200 Bq/m3. It is necessary to carefully choose the constructive site, with the minimum concentration of radon in the soil. Our purpose is to carry out a cartographic analysis of radon intake from soil in the territory of Kazan. An important component is the creation of unique maps based on the measurement of radon escalation. The practical significance of the work lies in the application of the results for making management decisions, in engineering and environmental surveys, for conducting hygienic assessments, or simply being used by citizens for informational purposes.

General anxiety and depression are associated with the physical activity and social interaction levels: Study in Argentinean university students during the COVID-19 outbreak

Background Due to the coronavirus disease 2019 (COVID-19), the planet is going through a historical time of exceptional concern and uncertainty, which impacts people mental health. Here, we explored the levels of depression and Generalized Anxiety Disorder (GAD) and their relation with the degree of physical activity and social interaction during the pandemic. Methods We performed a structured survey containing the PHQ-9 and GAD-7 tests to evaluate depressive symptoms and GAD levels. We also asked about weekly physical activity and the level of social interaction. We surveyed two groups of University students in the Buenos Aires Metropolitan Area: an internal group from the Instituto Tecnologico de Buenos Aires (ITBA), and an external group of students from multiple universities. The survey was conducted in late October/early-November 2020, after a peak of contagions. Some of the participants were surveyed again in January 2021, during academic holidays and after a valley of contagion, for longitudinal analysis Results Our data show that men and women of both groups exhibited a significant positive linear correlation between depression and GAD levels. Moreover, low levels of depression and anxiety were associated with performing physical activity for more than two days a week and to longer periods of social interaction. Finally, the second survey revealed a decrease of the symptoms. Conclusions Our results suggest that performing regular physical activity and avoiding long periods of social isolation gave benefits to mental health. We suggest that public policies could consider protecting these behaviors under health and safety standards.

New Nutritional Perspectives in the Context of Chronic Disease Patient Management

As living standards change with the development of modern industry and social encounters, people tend to change their lifestyle and environment exposure along with their psychophysiological factors, leading to an imbalance of homeostasis and increasing the risk for chronic diseases. In addition to ingredients, methods, and food conditions storage and processing, the use of additives and certain new foods have facilitated the increased occurrence of chronic diseases in children or adults. The interaction of some components of the food system with enzymes that metabolize different types of drugs can affect the body's clearance and therapeutic index.The objective of this chapter was to present the general principles of food development for special nutritional conditions, also the adjuvants used for chronic disease status improvement, under the condition of nutritional nutrivigilence and food safety standards, and specific to introduce an adjuvant food for atopic dermatitis management.

Analysis of the mechanical behavior of adobe walls without reinforcement through computational modelling

The construction of civil structures on land has played an important role for centuries, however, due to the seismic requirements and the minimum safety standards that are currently required for any structure, this type of construction has been lagged, it is denoted that the related regulations they are widely dispersed and in most cases. In developed countries, numerous technical and legal problems arise to carry out construction with these materials. In relation to this work, a set of models of raw earth type walls are presented, through the SAP 2000 software, having as a supply of the mechanical properties of this material the Peruvian regulation E.080. For the analysis of these models, a static linear analysis for finite elements and a stress analysis of the service limit state concept were studied. Finally, the models with their respective stress studies, management and design recommendations are presented under the criteria of the analyses carried out, leaving open the possibility of both carrying out an experimental phase to develop the analogy with the postulates and proposed results, as well as such as the option to perform a static pressure analysis by finite elements in order to achieve greater precision and calibration of the model with respect to what can be evidenced in laboratory tests.

Analysis of environmental hazards in the system «children's playground – urbanized area»

The article presents the results of the study of environmental pollution by methods of biological indication. The objects of research are children's playgrounds which are influenced by the negative anthropogenic factors. A child's body is more vulnerable to anthropogenic stresses. Car exhaust gases can have a negative impact on the respiratory, cardiovascular, nervous and other systems. Excessive noise pollution not only affects your hearing, but also other organs and systems. In addition, noise can increase stress hormone levels. The aim of the study is to identify the main adverse factors affecting playgrounds in large cities. Despite there are the sanitary standards for the placement of playgrounds in large cities, it was found that about 50 % of all playgrounds were located in violation of environmental safety standards. As part of the work, an inventory of children's playgrounds and sports grounds in the cities of Kyiv, Kharkiv and Dnipro was carried out. The author carried out experimental research on some playgrounds using biological indication methods. The method of lichen indication revealed that four out of ten playgrounds in Kharkiv have a high level of air pollution, and two out of ten in Kyiv and Dnipro. This is confirmed by the biotesting method. It was found that one of the methods of solving the problem of excessive anthropogenic load on the objects of study is planting greenery. It is experimentally established that green plantations are able to reduce the level of noise pollution by 4–6 dB and absorb pollutants. In addition to reducing the anthropogenic load, the greening of playgrounds has an impact on improving the microclimate of the urban environment, and developing the visual qualities of urbanised landscapes
