    An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the explicit predictor scheme. The proposedmethod is computationally more efficient when compared to the existing filtering techniques used for the stabilization of explicit MOT schemes. Numerical results presented in this paper demonstrate that the proposed method maintains its stability even when applied to the analysis of electromagnetic wave interactions with electrically large structures meshed using approximately half a million discretization elements

    Technical Note: High-resolution mineralogical database of dust-productive soils for atmospheric dust modeling

    Dust storms and associated mineral aerosol transport are driven primarily by meso- and synoptic-scale atmospheric processes. It is therefore essential that the dust aerosol process and background atmospheric conditions that drive dust emissions and atmospheric transport are represented with sufficiently well-resolved spatial and temporal features. The effects of airborne dust interactions with the environment determine the mineral composition of dust particles. The fractions of various minerals in aerosol are determined by the mineral composition of arid soils; therefore, a high-resolution specification of the mineral and physical properties of dust sources is needed. <br></br> Several current dust atmospheric models simulate and predict the evolution of dust concentrations; however, in most cases, these models do not consider the fractions of minerals in the dust. The accumulated knowledge about the impacts of the mineral composition in dust on weather and climate processes emphasizes the importance of including minerals in modeling systems. Accordingly, in this study, we developed a global dataset consisting of the mineral composition of the current potentially dust-producing soils. In our study, we (a) mapped mineral data to a high-resolution 30 s grid, (b) included several mineral-carrying soil types in dust-productive regions that were not considered in previous studies, and (c) included phosphorus

    The Middle Mediterranean is characterized by long, hot, and dry summers, significant historical and cultural values, and the warm Mediterranean sea, making it attractive for coastal tourism. Given these characteristics, the goal of our paper is to analyze the influence of summer temperatures in the region of the Middle Mediterranean on the values of underlying economic and tourism indicators. The method of simple linear correlation and regression was used. Based on the results of testing, we came to the conclusion that the temperatures in the summer months have no significant influence on selected economic and tourism indicators. Also, we conclude that social factors have the greatest influence on these indicators. The coefficients of variation are calculated in the observed period to analyze the variability of the tested values. It could not be identified a statistically significant relationship of indicators with summer temperatures

    Received December 10, 2018; accepted March 18, 2019.Дата поступления 10 декабря 2018 г.; дата принятия к печати 18 марта 2019 г.The Northern Sea Route (NSR) and the opportunities it offers for international transportation networks is widely discussed not only in academic literature but also by the wider public. The purpose of this article is to analyze the economic and logistical prerequisites for the development of the NSR-based project, its opportunities and threats in the light of Russia’s regional development. The article also focuses on the potential of the sea port of Sabetta, which may be turned into a transnational transport hub. The possibility of development of intermodal terminals is also discussed. The project presented in this article is based on the multimodal transport approach. The methodological framework relies on the method of branches, arbitrary variation in network programming, and graphical modelling. The analysis has shown that in its current state, the transportation network is insufficient and requires further expansion and modernization. The authors conclude that the capacities of Sabetta need to be supplemented with a modern network of railway, river and motor transport. This project may be expected to become a driver for regional development of the Urals and Siberia, create new jobs and attract foreign investment. The results of the study can be used for strategic planning of regional development of Russia’s northern regions.Северный морской путь (СМП) и его возможности для развития международных транспортных сетей широко обсуждаются не только в научной литературе, но и среди широкой общественности. Целью данной статьи является анализ экономических и логистических предпосылок для развития проекта, основанного на СМП, его возможностей и угроз в свете регионального развития России. В статье также рассматривается потенциал морского порта Сабетта, который может быть превращен в транснациональный транспортный узел. Также обсуждается возможность развития интермодальных терминалов. Проект, представленный в этой статье, основан на мультимодальном транспортном подходе. Методологическая основа опирается на метод ветвей и графическое моделирование. Анализ показал, что в своем нынешнем состоянии транспортная сеть недостаточна и требует дальнейшего расширения и модернизации. Авторы приходят к выводу, что возможности Сабетты необходимо дополнить современной сетью железнодорожного, речного и автомобильного транспорта. Можно ожидать, что этот проект станет драйвером регионального развития Урала и Сибири, создания новых рабочих мест и привлечения иностранных инвестиций. Результаты исследования могут быть использованы для стратегического планирования регионального развития северных регионов России.The work is carried out based on the task on fulfillment of government contractual work in the field of scientific activities as a part of base portion of the state task of the Ministry of Education and Science of the Russian Federation to Ural State Forest Engineering University (the No. 26.8660.2017/8.9 “The Research Methodology of Forms of Economic and Technological Reality in the Aspect of Sustainable Forest Management”).

    Green Economy: Definition and Main Directions of Development

    Full text link
    Сurrently, a set of global environmental and economic threats and challenges is forcing world economic science to find new ways of development of the world economy. A new model of economic growth must satisfy two main criteria: firstly, to find a qualitatively new path of growth, and, secondly, to ensure the safety and improve environmental quality for human habitation, i.e. to provide new economic growth without negative consequences for the environment. Many modern scientists see the solution to these problems in a relatively new trend in the economy that has been existing for over 30 years - the green economy. Top politicians and civil servants in leading economies echo their view. In this regard, the author has conducted in the present article the analysis of existing definitions of the green economy and has identified that many of them do not always agree on how to interpret and define the notion. The author has investigated the definition and formulation of various existing theories. The author has also examined the available Russian and international studies on the topic of sustainable development and green economy. During the research the methods of scientific analysis, comparison and synthesis were used. As the result of the research, the author has come to a conclusion about the necessity of developing a new definition of the green economy which would clearly explain its essence. The author emphasizes that the concept of green economy does not replace sustainable development, but achieving the sustainability of a nation depends almost entirely on the formation of the “right” kind of economy.В настоящее время совокупность глобальных экологических и экономических угроз и вызовов поставила мировую экономическую науку перед необходимостью поиска нового пути развития экономики мира. Новая модель экономического роста должна удовлетворять двум основным критериям: во-первых, найти качественно новое направление роста, во-вторых, обеспечить сохранность и улучшение качества окружающей среды для проживания человека, то есть обеспечить новый экономический рост без негативных последствий для окружающей среды. Многие современные ученые видят решение этих задач в относительно новом направлении в экономике, существующем чуть более 30 лет, – «зеленой» экономике. Их мнение разделяют и ведущие политики и государственные служащие мировых экономических держав. В связи с этим в настоящей статье автор провел анализ существующих определений «зеленой» экономики и выявил множество не всегда схожих мнений и трактовок ее определения. Автор осуществил поиск и формулировку наиболее точного и емкого современного определения «зеленой» экономики. Автором были изучены российские и международные научные исследования по теме устойчивого развития и «зеленой» экономики. В процессе исследования использовались методы научного анализа, сравнения и синтеза. В результате автор приходит к выводу о необходимости разработки нового определения «зеленой» экономики, которое однозначно определит ее сущность. В заключении автор акцентирует внимание, что концепция «зеленой» экономики не заменяет собой концепцию устойчивого развития, но достижение устойчивости государства почти полностью зависит от формирования «правильной» экономики.Работа ведется на основании задания на выполнение госзаказа в сфере научной деятельности в рамках базовой части государственного задания Министерства образования и науки Российской Федерации Уральский государственный лесотехнический университет (тема № 26.8660.2017/8.9 «Методология исследований форм экономико-технологической реальности в аспекте устойчивого управления лесопользованием»
