The article clarifies the concept of “virtual information educational environment” (VIEE) and examines the researchers’ views on its meaning exposed in the scientific literature. The article determines the didactic potential of the virtual information educational environment for the geography students training based on the analysis of the authors’ experience of blended learning by means of the Google Classroom. It also specifies the features (immersion, interactivity, and dynamism, sense of presence, continuity, and causality). The authors highlighted the advantages of virtual information educational environment implementation, such as: increase of the efficiency of the educational process by intensifying the process of cognition and interpersonal interactive communication; continuous access to multimedia content both in Google Classroom and beyond; saving student time due to the absence of necessity to work out the training material “manually”; availability of virtual pages of the virtual class; individualization of the educational process; formation of informational culture of the geography students; and more productive learning of the educational material at the expense of IT educational facilities. Among the disadvantages the article mentions low level of computerization, insignificant quantity and low quality of software products, underestimation of the role of VIЕЕ in the professional training of geography students, and the lack of economic stimuli, etc., У статті роз'яснено поняття «віртуальне інформаційне освітнє середовище» (VIEE) та розглядається погляд дослідників на його значення, викладені в науковій літературі. У статті визначено дидактичний потенціал віртуального інформаційного освітнього середовища для навчання студентів з географії на основі аналізу досвіду авторів змішаного навчання за допомогою Google Classroom. Він також визначає особливості (зануреність, інтерактивність та динамізм, відчуття присутності, наступність та причинність). Автори виділили переваги впровадження віртуального інформаційного освітнього середовища, такі як: підвищення ефективності навчального процесу за рахунок інтенсифікації процесу пізнання та міжособистісного інтерактивного спілкування; постійний доступ до мультимедійного контенту як у Google Classroom, так і за його межами; економія часу студента через відсутність необхідності опрацьовувати навчальний матеріал «вручну»; наявність віртуальних сторінок віртуального класу; індивідуалізація навчального процесу; формування інформаційної культури студентів з географії; і більш продуктивне засвоєння навчального матеріалу за рахунок засобів інформатизації.

The article shows how external and internal macro-economic factors (the reduction of real income of the population, the depreciation of the local currency to the US dollar in 2014 -2015, the promotion of Crimea as a direction for health and resort services for Russian citizens) impact on the financial and economic indicators of health and resort organizations in Russia during 2012-2015. The calculations based on a variety of Federal Service of State Statistics data demonstrate the positive dynamics of the development of regional markets of health and resort services, due to the regional markets of health and resort services of Krasnodar, Stavropol and Altai regions and due to the inclusion of the Federal District of Crimea within the Russian macroeconomic indicators. The econometric model based on a sample of 272 organizations proves the hypothesis about the more beneficial impact of the changes in macroeconomic factors for large health and resort organizations (with a total annual revenue of 400 million roubles) compared with smaller organizations. It is expressed in the growth of sales profitability and annual revenue. The calculations have shown that the organization size as an independent variable in a sample of data related to 2014-2015, increased its positive influence on the dependent variable of annual revenue growth comparing to sampling for 2012-2013. The tough financial constraints in the country trigger the discussion of new opportunities and tools for the development of market conditions, which will stimulate the demand for investment in material and technical base renewal and innovations from the side of large health and resort organizations. In addition to improving the transport accessibility of federal resort regions and measures for promoting and improving the quality of the general health and resort infrastructure, there are discussions to create a favorable competitive environment, improve the public procurement system (including the procurement, Дана оценка влияния внешних и внутренних макроэкономических факторов на финансово-экономические показатели санаторно-курортных организаций России в 2012-2015 гг.

The paper examines the improvement of the energy-efficiency in Russian regions as one of the leading directions of Russia's response to the new global challenges and the implementation of Paris climate agreement (2015) on reducing of greenhouse gases emissions. The research aims at the justification of differentiated strategies and instruments to control energy-efficiency in Russian regions with respect to its key drivers. We focuse on a regional aspect as there are essential reserves and distinctions of regions by energy efficiency level, the need of problem areas' identification, generalization and systematization of positive experience. Based on actual data, we verify the hypothesis that the energy-intensity level of the gross regional product depends on the share of energy-intensive industries, on the region's land area and on climate characteristics. Institutional factors having positive or negative influence have to be regarded as well. We have untilized comparative method, correlation and cluster analyse, conceptions of new public government and control by results, applied to problems of energy-efficiency and climate risks. As a result, we have identified three groups of regions. In one of them, was no statistically significant dependence of the energy intensity from the applicable standard factors proved. The two other groups confirm this dependence, but with significant differences in the level of energy efficiency. Furthermore, the study shows the significance of regional sector structure factor and justifies differentiated strategies to reduce energy consumption by regional and federal regulators and their consideration in the Energy strategy 2035. The measures to improve the energy efficiency in the regions are to be integrated into the long-term strategy of the Russian Federation to reduce greenhouse gases emissions (2050); and the innovation activities and the quality of regional energy-efficiency management are to be considered and analised., Рассмотрены задачи Парижского соглашения, связанные с повышением энергетической, ресурсной и экологической эффективности национальной, секторальной и региональной экономик. Представлен эконометрический анализ факторов, воздействующих на уровень энергоэффективности в российских регионах.

The sample preparation of gold-bearing ores for the analysis is an important part of the gold fields’ chemical approbation. One of the operations in sample preparation is a control of the size of sample particles. Traditional sieve method to control the particle size is labor intensive and has low rapidity. In addition, the modern equipment for the particle-size analysis is of high cost. In order to implement a cheap, simple and express method to control the particle size of gold-bearing ores in production laboratories this paper presents an algorithm to control the crushing ratio of laboratory samples of gold-bearing ores. Using this new method, it is first necessary to carefully mix a fine sample and to spread it on a smooth surface of the table to form a layer of 5-7 mm thick, and then divide it into approximately equal squares. After this, an operator rubs the sample material with a finger at the control points, immersing the finger in the material until the contact with the polymeric film is made. If at the same time between the film and the finger there will be a sample particle with the size of 0.08-0.1 mm, the operator will have a steady I type tactile sensation (the sensation of the “fine sand”). If at the same time between the film and the finger there will be a sample particle with the size of more than 0.1 mm and less than 0.2 mm, the operator will feel a steady II type tactile sensation (the sensation of the separate grains). This procedure allows controlling the quality of the sample preparation. To control the crushing ratio of gold-bearing ores used in the routine analysis it is enough to use 9 control points. The developed algorithm of the organoleptic method to control the crushing quality was checked on a large group of samples, and its results agreed nicely with the results received using the classical sieve method. Using the organoleptic method, the quickness of control increases and the labor input of control decreases in comparison to the siev, The methods of antioxidant activity determination of foodstuffs using different indicator systems were Подготовка проб золотосодержащих руд к анализу является важной составляющей частью химического опробования месторождений. Одной из обязательных операций пробоподготовки является контроль степени измельчения частиц материала пробы. Традиционный ситовой метод определения крупности порошков отличается большой трудоемкостью и низкой экспрессностью. Современное оборудование для анализа гранулометрического состава частиц порошков является достаточно дорогим. В работе предложена простая, дешевая и экспрессная органолептическая методика контроля крупности частиц золотосодержащих руд, применимая в производственных лабораториях. Для этого тонкоизмельченную пробу тщательно перемешивают, распределяют на полимерной пленке слоем толщиной 5-7 мм, а слой делят вручную на приблизительно равные квадраты. Оператор погружает палец в материал пробы в каждом квадрате до контакта с полимерной пленкой и растирает пальцем порошок. Если при этом обнаружится частица пробы, имеющая размер 0.08-0.1 мм, то у оператора формируется устойчивое тактильное ощущение I типа: присутствие «мелкого песка». При наличии в пробе частиц размером более 0.1 мм и менее 0.2 мм у оператора, выполняющего контроль степени измельчения проб, формируется устойчивое тактильное ощущение II типа: присутствие в пробе отдельных крупинок. Эта градация позволяет контролировать качество подготовки проб. Показано, что для органолептической оценки степени измельчения проб золотосодержащих руд в рутинном пробирном анализе достаточно использовать 9 контрольных точек. Разработанный авторами алгоритм проверен на большой группе проб, показано его хорошее совпадение с результатами контроля, полученными с применением классического ситового анализа. При использовании органолептической методики повышается экспрессность и снижается трудоемкость контроля по сравнению с ситовым методом анализа.

Two modes of phloem loading have been proposed, apoplastic and symplastic, depending on the structure of sieve element-companion cell complexes (SE-CCCs) in minor vein phloem. Species are usually classified as either apoplastic or symplastic loaders although the cytology of SE-CCCs in minor veins of the majority of plants indicates that both mechanisms can be simultaneously involved in phloem loading. The functions of structurally different SE-CCCs in minor veins of the stachyose-translocating plant Alonsoa meridionalis were examined. A stachyose synthase gene, AmSTS1, was expressed in intermediary cells but not in the ordinary companion cell of the same vein. In contrast, sucrose transporter AmSUT1 protein was present in ordinary companion cells but not in the neighbouring intermediary cells. These data reveal the principles of phloem sap formation in A. meridionalis and, probably, in many other dicots. The two types of SE-CCCs within one and the same minor vein load different carbohydrates, using contrasting mechanisms for their delivery into the phloem. Lateral sieve pores in the minor vein phloem lead to mixing of the carbohydrates soon after loading. While symplastic and apoplastic pathways can function simultaneously during phloem loading, they are separated at the level of different SE-CCCs combined in phloem endings.
