Background. The building materials industry includes the production of cement, bricks and other materials. The state of the cement market is of particular interest. An analysis of recent research and publications has shown that in order to generalize and specify the situation on the Ukrainian cement market, it is necessary to analyse statistics on production, consumption and export-import operations with cement. The aim of the article is to establish trends in the development of production, con­sumption, export and import operations with cement in Ukraine. Materials and methods. The work used general scientific and special methods of analysis, as well as publicly available sources of statistical information. Results. According to the State Statistics Service of Ukraine, over the past five years there has been an increase in production of all types of cement in quantitative equi­valent by almost 13.4 %, refractory cements – by 57.1 %, and alumina cement, clinker-free slag cement and hydraulic cements – 1.8 times. During 2016–2020, there was a tendency to increase wholesale prices for M-400 cement. During this period, the price increased 1.6 times and is mainly due to higher prices for raw materials. The difference in retail prices for cement in the largest retail chains in Ukraine is 25 %, which is a significant fluctuation. The analysis of the dynamics of cement exports from Ukraine during 2015–2020 showed a tendency to increase its volumes by more than 2 times. If we compare the volumes of imports and exports of cement, in 2020 the volumes of cement imports exceeded the volumes of exports by 33.8 % in monetary terms. The largest volumes of cement in 2020 were imported to Ukraine from Turkey – 91 % of all deliveries, from Poland, Bulgaria, Lithuania and Germany – 2 % each, and from other countries only 1 %. During 2015–2020, the largest share in the structure of domestic cement exports abroad belonged to Romania, having increased almost 5 times in 2017–2020. In second place amongimporting countries there are Hungary and the Republic of Moldova. Conclusion. In recent years, the cement market in Ukraine is gradually deve­loping. The analysis of development trends showed that its main producers are several large groups – private joint-stock companies, which produce 99.8 % of the total volume of these products. Studies have shown that during 2014–2020 there was a slight increase in pro­duction and consumption of all types of cement in Ukraine. Monitoring of cement prices showed that during 2016–2020 there was an increase in wholesale prices for M-400 cement: in four years they increased by more than 60 %. There is a significant difference in retail prices of cement in the seven largest retail chains in Ukraine at 25 %. Analysis of the dynamics of cement exports from Ukraine in 2015–2020 showed that they more than doubled, but imports of this product in 2020 exceeded exports by 33.8 % in monetary terms.

Technological Study

Siliceous-carbonate rocks are widespread on the territory of the Republic of Dagestan, in which the total content of zeolites and opal-cristobalite-tridymite phase (OCT) exceeds 45 %, and the content of calcite is above 30 %. The rocks, composing a productive stratum (at least, most of it), lithologically correspond to opoka-like and highly siliceous limestones, zeolite-containing (10–15 %) and zeolite (40 % or more), weakly quartz and weakly clayey. However, they are distinguished from pure limestones by a low value of actual calcite part — often less than 50 %. Therefore, in this case, the section of the productive strata is defined as «folded by siliceous-carbonate zeolite-containing rocks.» Such rocks, in accordance with the results of laboratory and technological study, are considered as raw materials for the production of building materials. Zeolite-containing rocks are suitable for use as an additive in Portland cement, which will save cement clinker in the production process and improve the quality of cement. Prospecting works for zeolites and zeolite-containing rocks in the Levashinskaya (Levashinsky district) and Rubaschayskaya (Tabasaran and Kaitagsky districts) areas of Mountainous Dagestan were carried out by the non-metallic party of JSC Sevkavgeologiya in 2007–2009. The resources of siliceous zeolite-containing rocks are in the P1 category — 49.308 million tons, in the P2 category — 69.470 million tons. The predicted resources, their laboratory and technological properties (physicochemical, chemical, technological) indicate the possibility of creating a solid mineral resource base and construction of large complexes for the extraction and processing of zeolites and siliceous rocks in Levashinsky (Levoberezhny and Pravoberezhny areas) and Tabasaran (Dyubek area) regions of the Republic of Dagestan.

Bedtime Procrastination

Abstract Introduction Bedtime Procrastination (BP) is defined as the behavior of voluntarily delaying going to bed, without having external reasons for doing so. Recent research on procrastination behavior suggests that when negative emotions are elevated, procrastination behaviors can be triggered in order to find pleasure to avoid and alleviate them. Procrastination can also occur when there is difficulty regulating emotions. In addition, the reason for bedtime procrastination may be different depending on whether the individuals present with insomnia. According to previous studies, patients with insomnia may exhibit more pronounced negative avoidance of bedtime due to prolonged sleeplessness. Therefore, this study compared the difference between of the bedtime procrastination and the emotional regulation strategies between the insomnia group and the healthy group. Methods This study was conducted in 582 adults (mean age 23.06 ±2.16 years), 81.6% females. Individuals scoring higher than 15 on the Insomnia Severity Index (ISI) were classified into the insomnia group (n=375), and those less than 15 were classified into the healthy group (n=207). Participants completed the Bedtime Procrastination Scale (BPS), Emotional Regulation Strategies Checklist. Data was analyzed using descriptive statistics, chi square test, and independent t tests. Results The insomnia group had significantly higher bedtime procrastination scores than the healthy group (t=-6.241, p<.001), and also the avoidant/distractive regulation style score was significantly higher (t=-1.969, p<.05). In addition, the score of active regulation style was significantly lower in the insomnia group than in the healthy group (t=3.050, p<.01). There was no significant difference between the two groups in the support-seeking regulation style. Conclusion Based on these results, it was confirmed that there was a difference in the bedtime procrastination and the emotional regulation strategies between the insomnia group and the healthy group.

The state of Michigan has been constructing directional crossovers in the medians of boulevard roadways since the 1960s to alleviate the congestion and interlocking that were occurring at bidirectional crossover locations. The objective of this research is to investigate the safety benefits of divided roadway and directional crossover median designs. An investigation of the mean accident rates of roadways with boulevards compared to the mean accident rates of roadways with continuous center left-turn lanes revealed that there is a significant difference, with boulevard roadways having a lower mean accident rate for those Michigan roadways investigated. Investigation into the difference of the mean accident rates for boulevard roadways with medians of different widths indicated that roadways with medians greater than 9.15 m (30 ft) but less than 18.30 m (60 ft) had the lowest mean accident rate of the three median categories investigated. The difference was significant for most accident types when compared to roadways with medians less than or equal to 9.15 m (30 ft) and greater or equal to 18.30 m (60 ft). The investigation of the accident rates for boulevard roadways with directional and bidirectional signalized crossovers, while not conclusive, indicated that boulevard roadways with direction crossovers had a lower mean accident rate than boulevard roadways with bidirectional crossovers for signalized roadways.

The Moment

For a long time before dramatic recent events it has been clear that the German Democratic Republic has been in die position, embarrassing to a Marxist system, of having nothing generally marketable left except (to use the jargon) ‘superstructure’. The Luther celebrations conveniendy bolstered the implicit claim of the GDR to embody Saxony’s long-delayed revenge upon Prussia; still more conveniendy, they paid handsomely. Even the Francke celebrations probably paid their way, ruinous though his Orphan House has been allowed to become. When I was in Halle, a hard-pressed government had removed the statue of Handel (originally paid for in part by English subscriptions) for head-to-foot embellishment in gold leaf, and a Handel Festival office in the town was manned throughout the year. Bach is still more crucial, both to the republic’s need to pay its way and to the competition with the Federal Republic for the possession of the national tradition. There is no counterpart in Britain to the strength of the Passion-music tradition in East Germany. The celebrations which reach their peak in Easter Week at St Thomas’s, Leipzig, are like a cross between Wembley and Wimbledon here, the difference being that the black market in tickets is organized by the State for its own benefit. If Bach research in East Germany, based either on musicology or the Church, has remained an industry of overwhelming amplitude and technical complexity, the State has had its own Bach-research collective located in Leipzig, dedicated among other things to establishing the relation between Bach and the Enlightenment, that first chapter in the Marxist history of human liberation. Now that a good proportion of the population of the GDR seems bent on liberation by leaving the republic or sinking it, the moment seems ripe to take note for non-specialist readers of some of what has been achieved there in recent years.

Terrorist Acts

In this article, the authors analyze cyberterrorism as a threat to Ukraine's cyber security. The urgency of the issue declared in the paper is conditioned by the fact that fair number of terrorist acts intende to make harm to the interests of the state, can be committed today both in real world and in cyberspace. As such acts are committed using computer systems and are done in cyberspace, authors propose to define this type of socially dangerous acts as «cyberterrorism». The methodological basis of this study is a set of philosophical, general scientific, special scientific and other methods that are directly applied in legal researches. The authors have done the interpretation of terms making up the conceptual and categorical apparatus of the subject of research. The difference between information terrorism and cyberterrorism has been substantiated by the writers. The emphasis was placed on the necessity to create a Cyber Command that could react fast to challenges in the information security sphere of the state, including acts of cyberterrorism.

Industrial Risk

This article suggests ways to quickly assess the state of labor protection and ecology by calculating a number of indicators of industrial risk based on the information available in the modules for assessing labor protection by indicators of industrial risk. The efficiency of using the software proposed by the authors for the occupational health and safety management system based on a specific task from the modules "Personnel", "Events", "Equipment" and "Ecology", consisting of four main modules, is proved. In addition, this paper compares the matrix methods of risk assessment in the coordinate system "probability of an event or consequences of an event" of prevention and assessment of occupational risks for employees used in domestic and foreign practice in the occupational safety management system.Work on identifying harmful factors of accidents during the extraction, use and transportation of raw materials at industrial enterprises and assessing compliance with the requirements of the standards of the Republic of Kazakhstan should be carried out continuously. The main goal of the labor protection service is to create safe working conditions for employees at industrial enterprises, as well as to prevent occupational diseases of employees. In this regard, a system of accounting, analysis and assessment of the state of labor protection, as well as labor safety management, should work.

the use of secondary raw materials for the production of building materials is a modern trend in solving environmental problems. In the Republic of Crimea, dumps of secondary raw materials – phosphogypsum and lime dust – have accumulated in large quantities at various enterprises. The analysis of phosphogypsum, which has been in the dumps for more than 5 years, showed that by its quality indicators it can be attributed to the 2nd grade in accordance with GOST 4013-2019, and the specific effective activity of the material (Aeff) corresponds to the I class of materials, which makes it suitable for the production of gypsum binders. Prototypes-cylinders were made from a mixture of phosphogypsum with lime dust of 1:1 composition at a pressure of 30 MPa and then subjected to hardening according to three schemes, in order to separate the passage of various types of hardening and study each of them for the physico-mechanical properties of the resulting material. The analysis of experimental data made it possible to establish the effectiveness of simultaneous flow in the system of two types of hardening – carbonate and hydration for lime and phosphogypsum components of the raw mixture, respectively. As a result of the organization of a mixed type of hardening of gypsum-lime binder, samples with a compressive strength of 26.5 MPa and a softening coefficient of 0.63 were obtained within 90 minutes. The calcium carbonate formed in the process, which is the product of the reaction between calcium hydroxide and carbon dioxide, significantly increases the water resistance of the hydration products of gypsum binder. It is established that with an optimal combination of technological factors and hardening conditions, a significant increase in the physical and mechanical characteristics of the carbonized material is possible in a short time.

A series of scientific and economic experiments have already been conducted to determine the norms for including local non-traditional feed additives in the rations of cattle, but they were not sufficient for the rational use of these feed additives. In order to determine the effectiveness of the use of local feed additives a scientific and economic experiment has been carried out under the environments of the APC “Krestyakh” in the Suntarsky district. Two groups of first-calf heifers have been selected per 50 heads in each. The groups have been formed by using the method of analogues. The environments of housing in all groups have been the same. The difference was that the experimental group of first-calf heifers have received from the local unconventional feed additives (zeolite khongurin, sapropel and Kempendyaskay salt). The results of the production test have shown that the experimental group of first-calf heifers exceeded the control group’s analogues in terms of milk yield by 233,4 kg or 9,4 %. Experimental group of first-calf heifers has had more high content of fat in milk 0,17 abs.%. When recalculating the content of fat in milk for 4 %, the difference in gross milk yield between the groups was 16,73 t or 14,3 % in favor of the experimental group. Economic analysis of the results of research and production experiment has shown that there was a significant difference in profit between the groups. So, in the control group it was 462 247,46 rubles, and in the experimental group 528 444,43 rubles. Additional profit in the experimental group was equal to 66 196,97 rubles, while the level of profitability was 8,2 %. Thus, the results of the research have shown that first-calf heifers of Simmental breed that received local non-traditional feed additives had higher milk productivity.
