Creating a flipped classroom with Ted-ED

The number of educators reversing the traditional teaching mode is constantly increasing. Those who have flipped their classrooms report numerous benefits, which are described in the paper. The analysis of data brings us to the conclusion that the flipped classroom model contributes to the personalization of instruction by taking into account the individual abilities of students as well as their motivational, collaborative and educational needs. According to the speakers’ experience, one of the most effective platforms to be used in EFL flipped classroom is Ted-ED. The paper focuses on the positive outcome of its usage

Electroless deposition and Electroplating of Metals

The present paper summarizes the main results of the research on the electroless and electrochemical metal deposition from aqueous solutions, which has been carried out in the Research Institute of Physical-Chemical problems of the Belarussian State University and at the Department of Inorganic Chemistry of the BSU for the last three decades. The paper covers the following problems: the main peculiarities of electroless and electrochemical deposition of copper, nickel, Ni-B,Ni-P, gold films 0.1-30 mkm and more in thickness, their phase composition, morphology and properties; the characteristic features of of hydrometallurgic allowing (e.g. electroless and electrochemical deposition of a number of binary alloy coatings such as Cu-Ni, Cu-Cd, Cu-Sn, Cu-Zn, Ni-Sn, Ni-W, Ni-Mo), methods of their chemical and phase composition and microstructure regulation, together with correlation between these parameters and alloy properties; the methods for composite metal and alloy film plating from solutions with production of materials including metal oxides and thus possessing unusual and useful properties; the peculiarities of metal film plating onto dielectrics with production of continuous films and metal conductive patterns without the use of photoresists

The role of intensification of educational process in forming stress resistance of students of educational psychologists

The article analyzes the stress as the system dynamic characteristics of the individual and focuses on the possibility of forming of stress resistance of students-psychologists in the framework of intensification of the educational processПроводится анализ стрессоустойчивости как системной динамической характеристики личности. Внимание акцентируется на возможности формирования стрессоустойчивости студентов педагогов-психологов в условиях интенсификации образовательного процесс

Rational use of forest as a renewable natural resource

This article is devoted to the formation of a mechanism for the rational use of forests as a renewable natural resource, including transfer of forest areas in rent taking into account market indicators, advantages and disadvantages in the process of timber sales. The total income received in the form of fees for the use of forest fund and for the use of forests in 2016 in the Russian Federation is amounted to 24.4 billion rubles, which is 0.9 billion rubles (by 3.8%) more compared with the previous year. According to the state report of the Ministry of Natural Resources and Ecology, in the reporting 2016 year this payment was received in the amount of 27.8 billion rubles, which is 3.4 billion rubles (almost 14%) more than in 2015. Thus, due to the fact that Russia's natural forest resources constitute powerful strategic competitive advantage in the world economic system, the article, on the basis of the system approach, reveals correlation between the level of rent payments and profitability from the sale of round wood, taking into account harvested and considered assortments, which allows forming forest payments on the basis of domestic and export market prices and as a result increasing financial contribution from the use of forests to the national budget.peer-reviewe

Ecologically based sediment quality criteria of the oil content for freshwater ecosystems on example of Kuibishev water reservoir

This article presents the criteria of sediment quality assessment for oil content according the integrated approach which based on chemical, ecological and toxicological data derived from a TRIAD monitoring network. The ecological criteria (the lowest effect level and the severe effect level) were calculated for oil content in sediments of Kuibyshev water reservoir on the base of benthos taxa occurrence. For the toxicological data, the threshold effect level and probable effect level were calculated, based on the results of the toxicological acute pore water and solid phase tests. The sediment quality guideline (49 mg/kg) is as a consensus value of the lowest effect level and threshold effect level. Presented criteria can be used for ecological risk assessment for benthic community in condition of cruel oil contamination

The human health risk assessment from contaminated air in the oil-producing areas (on the example of Novoshehminsky Region of the Republic of Tatarstan)

© 2014 AENSI Publisher All rights reserved. Based on the analysis of the monitoring results the air quality evaluation is provided and the incidence level of oil-producing Novosheshminsky region of the Republic of Tatarstan during the period of 2005-2009. Despite the satisfactory air quality, there is the growth of a number of systemic and autoimmune diseases (blood, blood-forming organs diseases, cancer, the endocrine system diseases) among the district population. The calculated level of non-cancer inhalation risk to public health made 11.0 (extremely high) for children and 2.4 (average) for an adult. The exponential nature of the relationship between the blood diseases, blood-forming organs, autoimmune diseases spread among children and the value of non-cancer risk reflects the presence of the cumulative effect of exposure to low concentrations of pollutants in ambient air on the most vulnerable children of the population
