Трансформация мировой автомобильной промышленности

The world industry is on a threshold of a new development cycle which is characterized by emergence of breakthrough technologies: distributed ledger technology, drone-type devices, 3D printing, virtual reality, Internet of things, augmented reality etc. Due to these technologies fundamental changes will take place in the majority of economic branches. The automotive industry is not an exception. This industry plays one of the key roles in economy in a great number of countries and changes occurring in it lead not only to creation of new products, technical processes but these changes also entail improvement of the industrial base which has been already created. The Republic of Belarus considers an automotive industry as one of key industries for its economy and its efficiency has a high dependency factor pertaining to speed of innovation emergence and implementation that is strategically important aspect of increase in competitiveness both on current sales markets and on potential ones. The paper pays a special attention to two main trends arising in the course of forming a new industrialization: increase in environmentally-friendly fuel systems and digital transformation. Problems of world ecology have exerted a considerable impact on developments in the field of alternative energy sources. Speed of development and promotion of electric vehicles considerably exceed “breakthrough” innovation developments of the past. However a great number of factors can have a significant effect on the future of electric vehicles and two of them are thoroughly considered in the paper: cost of energy (batteries) and price of oil (at the price of about 20 USD for barrel the development rate will considerably decrease). Besides the matter of environmental friendliness the paper pays attention to services of digital transformation. The world has already presented examples pertaining to usage of remote control for dump trucks, telematics etc. Such an approach makes it possible for organizations to optimize substantially an expenditure budget and doing so we increase resource use efficiency. The paper also contains a review of innovations in the automotive industry of the Republic of Belarus: BelGee electric cars, Belkommunmash electrobuses, developments of large industrial equipment.Мировая промышленность находится на пороге нового витка развития, характеризующегося появлением таких прорывных технологий, как: блокчейн, беспилотные устройства, трехмерная печать, виртуальная реальность, Интернет вещей, дополненная реальность и т. д. В результате этого коренные изменения произойдут в большинстве отраслей экономики. Автомобилестроение не исключение. Данная отрасль играет одну из ключевых ролей в экономике множества государств, и изменения, происходящие в ней, приводят не только к созданию новых продуктов, технических процессов, но и к совершенствованию уже имеющегося производственного плацдарма. В частности, для Республики Беларусь автомобильная промышленность – одна из ключевых отраслей экономики, и ее эффективность имеет высокую степень зависимости от скорости возникновения и реализации инноваций – стратегически важного аспекта повышения конкурентоспособности как на текущих, так и на потенциальных рынках сбыта. В статье уделено внимание двум основным трендам, возникающим в процессе формирования новой индустриализации: повышению экологичности топливных систем и цифровой трансформации. Проблемы мировой экологии оказали значительное влияние на разработки в сфере альтернативных источников энергии. Скорость развития и популяризации электромобилей значительно превосходит «прорывные» инновационные разработки прошлого. Однако на будущее электромобилей могут значительно повлиять множество факторов, два из которых подробно рассмотрены в статье: стоимость энергии (батарей) и цена нефти (при цене около 20 дол. за баррель темп развития значительно снизится). Помимо вопроса экологичности, уделено внимание сервисам цифровой трансформации. В мире уже существуют примеры использования удаленного управления карьерными самосвалами, телематики и т. д. Все это позволяет организациям значительно оптимизировать расходную часть бизнеса, тем самым увеличив эффективность использования имеющихся ресурсов. Приводится обзор инноваций в автомобилестроительной отрасли Беларуси (электромобили «БелДжи», электробусы «Белкоммунмаш», разработки представителей крупной промышленной техники)

The effect of growing conditions and the year of reproduction on sowing qualities of seeds, morphological and physiological characteristics in sprouts of Vigna radiata (L.) R. Wilczek

Background. Mung bean (Vigna radiata (L.) R. Wilczek) sprouts are of high nutritional value and are very popular in the world, as they are a source of nutrients and bioactive compounds. In Russia, the consumption of V. radiata sprouts is only beginning to develop. Growing this crop for microgreens on a commercial scale requires cultivars with a rapid development rate and higher weight of sprouts. With this in view, the aim of this research was to study the effect of growing conditions and the genotype on morphological and physiological parameters of mung bean seeds and sprouts.Methods. Mung bean accessions from the VIR collection were analyzed. Germination energy, seed germination and seed vigor, and morphological characteristics were evaluated in seeds and sprouts of 16,000 plants. Four plant reproductions grown at Astrakhan (2015, 2017), Kuban (2005) and Adler (2016) Experiment Stations of VIR were studied. The effect produced by growing conditions and the genotype on morphological and physiological parameters of plants was identified using one- and two-way analyses of variance. Correlations between the traits were assessed using correlation and component analyses.Results. Specific individual features of the accessions produced the strongest effect on morphological and physiological characteristics of seeds and sprouts; weather conditions, the place and year of reproduction, to a lesser extent. Sowing quality of seeds depended more on the precipitation amount during the growing season than on the sum of active temperatures. When formed under dry conditions, seeds manifested better seed germination, germination energy of seeds, and seed vigor. Accessions with high and stable levels of seed germination, germination energy, and seed vigor, and weight of sprouts were identified

Исследование минерализующего действия фосфогипса при обжиге цементного клинкера

Phosphogypsum accumulated in the dumps of JSC «Gomel Chemical Plant» in amount as much as 20 million tons could be one of the promising raw materials for cement production. The use of phosphogypsum in the cement industry as a mineral-izer for clinker burning process has been studied. It has been shown that the introduction of phosphogypsum in the feed mixture has a positive effect on the binding of calcium oxide during burning. The phase composition of clinkers and main properties of portland cement produced with the use of phosphogypsum, have been investigated.Одним из перспективных сырьевых компонентов в производстве цемента может быть фосфогипс, накопившийся в отвалах ОАО «Гомельский химический завод» в количестве свыше 20 млн т. Приведены результаты исследований по использованию фосфогипса в цементной промышленности в качестве минерализатора процесса обжига клинкеров. Показано, что введение фосфогипса в сырьевую смесь оказывает положительное влияние на связывание оксида кальция при обжиге. Изучен фазовый состав клинкеров и основные свойства портландцементов, полученных с использованием фосфогипса
