Полиолы являются веществами, крайне востребованными во многих отраслях современных химической, пищевой, парфюмерной, медицинской и топливной промышленностей. Их широко используют в производстве ПАВ, синтетических смол, лаков, олифы, витамина С, пищевых продуктов. В настоящее время усилия многих научных коллективов сосредоточены на разработке новых, эффективных и экологически безопасных способов получения полиолов из растительной биомассы, в первую очередь, из целлюлозы. Огромные природные возобновляемые запасы данного биополимера способны полностью удовлетворить потребности современной промышленности в полиспиртах, что особенно актуально с учѐтом перспективы постепенного истощения запасов углеводородных ископаемых. Одностадийный процесс конверсии целлюлозы до полиспиртов ( one-pot процесс), в присутствии гетерогенных металлосодержащих катализаторов известен достаточно давно, однако в литературе практически отсутствуют исследования, направленные на изучение его физико-химических основ и кинетики. Очевидно, что результаты таких исследований могут способствовать повышению эффективности процесса конверсии целлюлозы, стать фундаментальной основой новых, усовершенствованных технологий переработки целлюлозной биомассы в ценные химикаты.
Polyols are substances that are extremely in demand in many branches of modern chemical, food, perfume, medical and fuel industries. They are widely used in the production of surfactants, synthetic resins, lacquers, drying oil, vitamin C, food products. Currently, the efforts of many research teams are focused on the development of new, effective and environmentally friendly methods for obtaining polyols from plant biomass, primarily from cellulose. Huge natural renewable reserves of this biopolymer are able to fully meet the needs of modern industry in poly-alcohols, which is especially important given the prospect of gradual depletion of hydrocarbon reserves. The one-pot process of converting cellulose to poly-alcohols in the presence of heterogeneous metal-containing catalysts has been known for a long time, but there are practically no studies in the literature aimed at studying its physico-chemical bases and kinetics. It is obvious that the results of such studies can contribute to improving the efficiency of the cellulose conversion process, become the fundamental basis of new, improved technologies for processing cellulose biomass into valuable chemicals.

Published: January 2023

Knowing the teaching strategy is very important in the teaching and learning process because it dramatically influences the students' outcomes. Many studies on teaching strategies have been done in many parts of the world. However, the studies on teaching strategies in the pandemic era applied by the teachers in a reputable school in Indonesia are rarely discussed. Thus, this research aims to explore a reputable school's teachers' experiences in applying strategies during covid-19. There were three senior high school teachers from one of the reputable schools in Bengkulu who participated in this research. This research adapted a case study design by using a semi-structured interview as the research instrument. The interview data were recorded, transcribed, and coded into several themes based on the focus of this research. The result showed that the teachers tended to use the same materials, such as books from the government and materials from the internet. In addition, the teachers dominantly use zoom meetings for the teaching media. Meanwhile, they had their preferences on the teaching strategies. Generally, the teachers prefer to implement online discussion, computer-based learning exercises, online collaboration projects, online lectures, independent study, and online learning using social networking as the teaching strategies. The result of this study can be used as a guideline for teachers from other schools in implementing the teaching strategies, especially in online teaching.

Lateral wear of the locomotive wheel flange is one of the main types of wear that occurs during rolling stock operation. An important characteristic of a rail wheel rim is its wear resistance, which directly depends on the carbon content in steel. The carbon content in wheel steel of group 2 in the amount of 0,55–0,65 is due to the fact that at its lower concentration, the proportion of grain boundary ferrite increases, which leads to a decrease in the contact strength of wheels, and a higher one leads to a tendency to brittle fracture.The increased carbon content makes it possible to harden the surface of steel. Plasma and laser hardening technologies can be used to reduce tyre flange wear and increase the service life of locomotive wheelsets.The objective of this work is to determine advantages and disadvantages of technologies for laser and plasma hardening of working surfaces of tyres of wheelsets of railway rolling stock.The comparative analysis related to microstructure and microhardness of wheelsets tyres of the 2TE25KM diesel locomotive which are made of wheel steel of group 2 according to GOST 398-2010 state standard and hardened respectively by plasma and laser hardening.The tasks set were solved using theoretical and experimental research methods. The preparation and study of hardened samples was carried out using the equipment of the testing laboratory of LLC Scientific and Technical Association «IRE-Polus».A study referred to hardened zones in various areas and sections of the tyre. Tribological tests concerned wear resistance of specimens hardened with a high-power fiber laser. The main advantages and disadvantages of laser and plasma hardening processes are revealed.The conducted studies allow making a conclusion that the use of laser hardening technology for hardening wheelsets tyres, as an alternative to the plasma hardening process, is highly promising.

Published: January 2023

The process of supply of enterprises with material and equipment is one of the most important conditions for uninterrupted and productive performance of economic entities. Therefore, it is important to pay attention not only to the number of transactions and purchases, and rational use of those resources but also to the time of delivery to enterprises, to the travel time. Delay in supply of necessary resources may cause reduction in production efficiency that further will result in losses for enterprises. This topic is relevant not only for individual business structures and organisations, or all over the national transport system, but from the regional aspect as well.The article using an example of Orenburg region considers not only general issues of development of regional transport and logistics system but also the features of rail transportation.The proposed classification of subsystems of supply chain management based on core activity indicators supposes further in-depth diagnostics to reveal the causes of occurrence of signs of inefficiency in rail transportation and their prompt elimination.
