AbstractThe question of silicate glass chemical durability is at the heart of many industrial and environmental issues, with certain glasses, such as bioglasses, needing to transform rapidly, while others, like nuclear glasses, extremely slowly. Due to the wide diversity of the chemical composition for these types of materials and their metastability—no thermodynamic equilibrium can be reached between glass and solution—the evaluation of chemical durability remains a scientific challenge. In this article, we review the current state of knowledge on glass alteration mechanisms and kinetics, and point to some perspectives for glasses for which no direct experimental validation is currently possible. Thanks to the development of novel techniques and international collaborations, a better understanding of the mechanisms involved has been achieved. Mechanistic models have been developed at some specific scales, although holistic models still need further development to link the various scales and perform reliable predictions.

The article notes that the growing popularity of healthy lifestyles contributes to the increase in consumption of fruits and berries. At the same time, the analysis of the dynamics of the gardening industry for 2000-2018 shows that the problem of providing fresh fruits and berries to the population remains one of the most important. Based on actual data, linear and logarithmic models of time series of key industry indicators for the period 2010 – 2019 have been compiled. Calculations showed that in the Russian Federation as a whole the trend of reduction of sown areas of perennial fruit plantations will continue with growth of yield and gross fees. In this regard, the issues of distribution and introduction of gardens of intensive type are updated. An overview of the views of domestic scientists-gardeners on the concept of “intensive garden” is given. It has been established that the distribution of intensive gardens is possible only if there are favorable natural and climatic conditions and a developed scientific and production base of nursery management. The current state and problems of gardening in one of the leading regions – the Republic of Dagestan - are considered. A significant technological lag of region in the further development of intensive horticulture has been identified. Various directions of intensification process in horticulture as the main and necessary condition of growth of efficient and sustainable production are summarized.

Studying the current state of cartography and ways of further developing the industry, the role of the map in the future of the society, new methods of promoting cartographic products is impossible without a deep scientific analyzing all the paths, events and factors influencing its formation and development throughout all the historic steps of cartographic production in Russia. In the article, the history of cartographic production in Russia is considered together with the development of private, state and military cartography, since, despite some differences, they have a common technical, technological and production basis. The author describes the stages of originating, formation and growth of industrial cartographic production from the beginning of the XVIII century until now. The connection between the change of political formations and technological structures with the mentioned stages of maps and atlases production is considered. Each stage is studied in detail, a step-by-step analysis was carried out, and the characteristics of each stage are described. All the events and facts are given in chronological order, highlighting especially significant moments influencing the evolution of cartographic production. The data on the volumes of printing and sales of atlases and maps by commercial and state enterprises are presented. The main trends and lines of further development of cartographic production in Russia are studied.

AbstractChina ishas a rich record of Holocene volcanism that is relatively little known outside the country. It is encountered in home to a number of volcanoes that have erupted in the Holocene. These range from large stratovolcanoes in the northeast, linked to subduction of the pPacific plate (e.g., Changbaishan); in , more diffuse volcanismsmaller volcanoes on the edges of the TibetTibetan margin, linked toassociated with the collision of India and AEurasia (e.g., Tengchong, Ashishan), and more isolated regions of volcanismcentres possibly linked topossibly resulting from mantle upwelling (e.g., volcanoes in Hainan island). This makes China a natural laboratory for studyingstudies of intraplate volcanism, yet the study of volcanology in China is young, with a significant increase in research only over the last 25 yearsand significant progress in understanding its nature and origins has been made over the past quarter century. To highlight recent advances and the current state of knowledge, thisHere, we introduce the first publication in English to provide a comprehensive survey of the state of knowledge and research highlights. special volume presents the first compilation of research on the active volcanoes of China in English. This first paper introduces the book, which coversAccordingly, we provide an overview of the dynamics, geology, geochemistry, volcanic histories and geophysical studies of the 14 volcanoesvolcanic areas that have erupted in theassociated with Holocene documented thus far. Our hope is that this special publication acts as The special publication represents a benchmark reference on the topic but, as importantly, we hope it will stimulatea resource to allow new, international collaborations to be developed to help understandaimed at deepening our understanding of the origins, history, hazards and associated risks from future eruptions of China's volcanoes.

Relevance. Vegetable growing is a traditional sector of agriculture in Azerbaijan. The republic has all the conditions for its development, both natural and socio-economic. Materials and methods. The aim of the research was to analyze the current state of vegetable growing in the republic, to identify the strengths and weaknesses of the industry, to determine the terms of support for producers from the state and branch science. Results. The gross harvest of vegetables has been steadily growing in the last decades, and by 2019 amounted to 1715 thousand tons. The yield of vegetables also increased during this period from 14, 7 to 21.9 t / ha. In door production area is approximately 4800 ha. The production of greenhouse vegetables is focused on the Russian market. The bottleneck in the industry is vegetable seed production, a market with a capacity of almost 20 million euros is occupied by foreign companies. At the same time, the agricultural producers get state support in the form of subsidies and soft loans and a full tax exemption. Industry science is also developing: the Research Institute of Vegetable Production has been reconstructed and fully equipped, special training organized for vegetable growers in the Azerbaijan State Agrarian University. Further development of the industry continues through the intensification and biologization of production, expanding the range and improving product quality.
