In connection with the reform of regulatory framework for construction sector of the Republic of Kazakhstan, the development of seismic zoning maps poses an urgent problem. The article presents a set of seismic microzoning maps of Almaty, developed on a new methodological basis for Kazakhstan, and provides explanatory materials on the development, understanding and use. Calculation of background seismic hazard was carried out in accordance with the basic provisions of Eurocode 8. Seismic microzoning included the implementation of two main tasks - the assessment of background seismicity and taking into account influence of soil conditions. Based on the analysis results, a set of maps have been arranged. When taking into account the influence of engineering and geological conditions, Russian and Kazakh works were used. The main maps ready for use in regulatory documents are provided. Analysis of capacities of the sediments of same age in different blocks made it possible to understand the dynamics of tectonic regime of the city territory. In the process of neotectonic activation, almost all previously existing tectonic disturbances were improved. In the contemporary relief of the urban area, most faults are not expressed.

Карты инженерно-геологического районирования являются основой для проведения работ по сейс- мическому микрорайонированию (СМР). Результаты инженерных изысканий позволяют формировать карты инженерно-геологического районирования. В последние годы, целенаправленные детальные изы- скания для целей СМР рутинных урбанизированных территорий изза отсутствия необходимого финанси- рования, как правило, не проводятся. Большей частью для решения проблемы используются результаты прошлых изысканий для различного рода проектируемых зданий и сооружений, разнесенные по времени. В работе предлагается использовать способ регистрации микросейсм, позволяющий достаточно надежно дифференцировать участки с различными грунтовыми условиями. При необходимости разрезы уточня- ются сейсморазведочными методами. В результате проведения исследований современными геофизическими методами подобным обра- зом были уточнены карты инженерно-геологического районирования гг. Владикавказ, Беслан, Ардон и Алагир. The maps of engineering-geological zonation are the basis for realization of seismic microzonation works (SMZ). The results of engineering investigations allow composing maps of engineering-geological zonation. As a rule, purposeful detail investigations for SMZ of routine urbanized territories are not carried out in recent years because of the absence of necessary financing. For the most part the results of the previous investigations for different kinds of designed buildings and constructions which are spread out in time are used for the problem solving. Microseisms recording technique which allows differentiating areas with different soil conditions quite reliably is offered for usage in the paper. Sections can be detailed with the help of seismic exploration methods if required. The maps of engineering-geological zonation of the cities Vladikavkaz, Beslan, Ardon and Alagir were detailed in a similar way as a result of investigations on the basis of modern geophysical methods.

For several years before the announcement of the global pandemic caused by the COVID-2019 infection, the restaurant services market in the city of Kazan, the capital of the Republic of Tatarstan, was represented by almost all formats of catering establishments: from fast-food to premium restaurants. Kazan was in first place in Russia and in the Volga Federal District in terms of the number of seats in cafes and restaurants per thousand inhabitants. However, in the context of a pandemic and quarantine, enterprises have suspended work. The conditions for getting out of self-isolation force us to reconsider the attitude of consumers to the problems of the restaurant business and how to solve them before and after the pandemic.

The work is devoted to the assessment of the atmospheric air on urbanized territories of Karaganda. This work determines the content of 11 pollutants. Measurements were carried out at 14 route posts with the maximum coverage of the entire city territory in June and January in order to obtain seasonal dynamics of atmospheric air pollution. As a result of measurements in July, the maximum single-time content of carbon monoxide, phenol, formaldehyde, hydrogen sulfide, and methyl mercaptans was recorded. In January, carbon monoxide predominates in the city’s air from pollutants, and increased concentrations of hydrogen sulfide are also observed in most parts of the city. Based on the results obtained, the atmospheric pollution index was calculated for 5 substances. Measurements of the pollutants were carried out at different times of the day. It was found, that contamination in almost all analyzed substances is higher in the daytime and in the evening. The main harmful impurities in the air of Karaganda are ozone, carbon monoxide, hydrogen sulfide, phenol, formaldehyde and methyl mercaptans. Ammonia was detected periodically. Based on the results the suggestions for improvement of the atmospheric air condition in the research territory were developed and adopted.

Abstract The development of the construction of high-rise residential buildings requires a separate approach, depending on the engineering and geological conditions of the site for seismic microzoning. There are not only engineering sectors but also large premises that will serve as business offices and technical centers in the underground part of high-rise buildings. In this regard, the foundation of the building goes to great depth. The influence of soil conditions at the level of abutment of the buildings’ foundation can be determined with seismic microzoning. As a result, the task of clarifying the projected construction site in construction is currently relevant. It includes the refinement of the seismic intensity of the construction site during the construction of high-rise buildings, which are located in different multilayer soil types.

Introduction. The important factors affecting health and performance of young people are the conditions of education, in particular, a comfortable microclimate in the classrooms of higher educational institutions. Materials and methods. In view of the urgency of this problem, an analysis was made of the microclimate parameters of educational organizations of different profiles (Ufa city, the Republic of Bashkortostan). 294 classrooms were studied in 22 buildings of 4 leading universities in Ufa. A total of 3,822 measurements were taken to determine the parameters of the microclimate. The analysis of ionizing radiation in the aerial environment of classrooms. There was performed determination of radon and its affiliated products content. In order to assess the conditions and lifestyle of students of 4 higher educational institutions of the city of Ufa, we conducted an anonymous survey of 1,820 students of I and IV years of education. Results. The average temperature in the classrooms of all universities studied was 23.9±0.09 C. The average relative humidity in all classrooms was 34.2 ± 0.42%. Analysis of ionizing radiation (radon and its daughter products decay) in the aerial environment of the classrooms and sports halls located in the basement determined that the average annual equivalent equilibrium volumetric activity of the radon daughter products (EROA ± Δ222Rn) ranged from 28 ± 14 to 69 ± 34.5 meter, which meets the requirements established by SanPiN. Conclusion. The hygienic assessment of the microclimate parameters of educational institutions of various profile revealed a number of deviations from the regulated norms. The results indicate the need to control the parameters of the microclimate, both from the administration of universities, and from the professors. According to the results of the study, recommendations were prepared for the management of higher educational institutions in Ufa.

Relevance. Characteristics of eruption of secondary teeth is of diagnostic and prognostic interest, is the basis for implementation of targeted therapeutic and preventive measures among children. No research has ever been carried out in Uzbekistan to study an age and gender regional features of secondary teeth eruption. The aim is to determine the timing and symmetry of secondary teeth eruption in children of the city of Tashkent of the Republic of Uzbekistan and comparative assessment with the children of different cities of Russia.Materials and methods. 3,834 children between 3 and 17 years were conducted dental examination. A comparative analysis was made of the initial, intermediate and final periods of eruption of secondary teeth for children of Uzbekistan (Tashkent city) and Russia (Saratov, Izhevsk and Sergach).Results. In Tashkent children of both gender, in most cases, lower teeth were erupted before than their antagonists. In girls, teeth were erupted earlier than their male counterparts. At the initial stage of eruption, asymmetry was more pronounced in boys than in girls, while in the middle and final stages it was more pronounced in the opposite direction. Observed asymmetry of antimere’s teeth were indicated left-handed permanent dentition in boys and right-handed in girls. Children of Tashkent city were observed permanent dentition in one group of teeth 1-16 months earlier, and in others – 1-24 months later than their peers in Russian cities. Revealed differences were more pronounced among boys than among girls. Children in Tashkent differed more from their peers in Sergach and less from those in Izhevsk. Conclusions. Regional peculiarities of permanent dentition in children of Tashkent city and revealed expressed differences with indicators of Russian children are the basis for development of separate age and  gender normative assessment permanent dentition tables for children of Uzbekistan.

Accounting education is taught in some private universities has impressed as stagnant knowledge, mechanical, and oriented material that causes a lot of students in general become saturated in the learning process. In Indonesia at several universities, almost all accounting courses little or no charge to enter the motivation, creativity, and mentality in the accounting curriculum-based motivation, creativity, and mentality can only he done well when formulated in a more complete firm of the curriculum. Therefore, this study examines the effect of motivation, creativity and mentality in accounting education to obtain empirical evidence. In this study using primary data obtained through questionnaires from a list of questions posed to accounting students in private universities in the city of Padang. The sample in this study was conducted with a purposive sampling technique where the sampling method was based on certain criteria, namely : involving student participants who majored in accounting class of 2010, 2011, and 2012 who had studied the sciences and overall accounting associated with accounting. Testing the hypothesis of this research is conducted with multiple regression analysis. The first hypothesis testing results found that motivation does not significantly influence accounting education in private universities Padang. The second hypothesis testing results found that creativity significantly influence accounting education in private universities Padang. The third hypothesis testing results found that significantly influence the mentality of accounting education in private universities Padang.

Thucydides reports that the Phoenicians were present throughout Sicily and traded with the Sicels. A tangible Phoenician presence in Sicily, as expressed by pottery, is attested only at the end of the eighth century bce. The earliest hypothetical Phoenician settlements of Solunt and Panormus are still almost unknown. This earliest phase is associated in particular with the city of Motya, where pottery and a few other finds testify to it. The Punic phase of the island is much clearer, with almost all indications coming from Motya and Selinus, which were not built over in Roman times. The Pfeilertempel, as emerged from Motya, could be regarded as the prototype for the Phoenician temple in Sicily. In turn, it is possible to recognize a characteristic type of temple of Punic Sicily, as particularly shown at Selinus, These shrines, as well as other elements of the Punic settlements like the houses, the fortifications, or the necropoleis, in particular from the fourth century bce onwards, are evidence of an advanced degree of Hellenization, framed within a Mediterranean koine.

AbstractIn this paper the site categorization criteria and the corresponding site amplification factors proposed in the 2021 draft of Part 1 of Eurocode 8 (2021-draft, CEN/TC250/SC8 Working Draft N1017) are first introduced and compared with the current version of Eurocode 8, as well as with site amplification factors from recent empirical ground motion prediction equations. Afterwards, these values are checked by two approaches. First, a wide dataset of strong motion records is built, where recording stations are classified according to 2021-draft, and the spectral amplifications are empirically estimated computing the site-to-site residuals from regional and global ground motion models for reference rock conditions. Second, a comprehensive parametric numerical study of one-dimensional (1D) site amplification is carried out, based on randomly generated shear-wave velocity profiles, classified according to the new criteria. A reasonably good agreement is found by both approaches. The most relevant discrepancies occur for the shallow soft soil conditions (soil category E) that, owing to the complex interaction of shear wave velocity, soil deposit thickness and frequency range of the excitation, show the largest scatter both in terms of records and of 1D numerical simulations. Furthermore, 1D numerical simulations for soft soil conditions tend to provide lower site amplification factors than 2021-draft, as well as lower than the corresponding site-to-site residuals from records, because of higher impact of non-linear (NL) site effects in the simulations. A site-specific study on NL effects at three KiK-net stations with a significantly large amount of high-intensity recorded ground motions gives support to the 2021-draft NL reduction factors, although the very limited number of recording stations allowing such analysis prevents deriving more general implications. In the presence of such controversial arguments, it is reasonable that a standard should adopt a prudent solution, with a limited reduction of the site amplification factors to account for NL soil response, while leaving the possibility to carry out site-specific estimations of such factors when sufficient information is available to model the ground strain dependency of local soil properties.
