Published: November 2024

This paper raises the dynamics of oligarchic power relations in the management of C-quarry mining resources in the form of stone in Noemuti District, North Central Timor Regency. This research uses the oligarchy theory of Jeffrey Winters as a basis for analysis in looking at mining problems that seem to be deadlocked when dealing with power authorities in resource management in the regions. The practice of oligarchy in Winters' theory uses 5 main approaches. But in this paper, it only limits to two approaches, namely the concentration of wealth and the concentration of power. Facing the dynamics of oligarchy that strengthens in local resource governance, on the other hand, presents resistance from civil society to take part in the legitimacy of power in the context of equitable distribution of resource management policies. The practice of community resistance is based on Sidney Tarrow's theory of collective challenge, common goals, solidarity and collective identity and maintaining the politics of resistance.

The study is devoted to the preparation of precursors of complex oxide systems by electrochemical method based on the processes of anodic dissolution of aluminium in the electrolyte containing Cl-, NO3-, Al3+, Zr4+, Y3+, Dy (III), Nd (III) ions. The synthesis of precursors of complex oxide systems was carried out in a coaxial diaphragmless electrochemical reactor with substantially different area electrodes. The process of precursor formation proceeds in the volume of the electrochemical reactor due to the interaction of electrogenerated Al3+, OH- ions and electrolyte components. It is caused by hydrolysis of anode dissolution products, formation of polyheteronuclear metal-hydroxo-aqua complexes, their polycondensation, formation of primary particles of solid phase and enlargement of the latter. A comparative analysis of the particle size distribution of samples differing in the content of Dy2O3 and Nd2O3 demonstrates the bimodal character of the distribution, expressed more clearly in the case of the system containing Nd. The average particle size of the synthesised precursors is approximately in the same range, except for the system containing Nd and obtained from an electrolyte with a higher content of this element. The results of particle size measurements are confirmed by electron microscopy data. These data correlate with the time dependence of ξ-potential of synthesised precursors of alumina-zirconium oxide systems containing REE. The proposed approach allows to obtain precursors of complex oxide systems based on aluminium, zirconium, REE oxides. Using X-ray fluorescence and particle size analysis methods, the particle size and chemical compositions of precursors of oxide systems were investigated.

Nanocomposites are widely used in many fields of science due to their impressive physical and chemical characteristics. Despite the fact that this class of composite materials has appeared relatively recently, there are a considerable number of methods for their production. When designing such materials, a special role should be given to nanocomponents and their production. This work examines the possibility of synthesizing nanosized iron (III) oxide and its mixtures with silicon dioxide and aluminum oxide in solutions of iron (III) nitrate with glycine, which can be used as a component of composite dispersion-strengthened materials. The synthesis of iron (III) oxide and its mixture with aluminum oxide and dioxide was carried out in the self-propagation mode for the system in the solid state. The solid state of the mixture corresponds to the residual amount of bound water - two moles per mole of Fe(NO₃)₃. When studying the process of preparation for synthesis, it was shown that the introduction of additives does not have a significant effect on the residual moisture content, but helps to reduce the combustion temperature by 22-175 ° C and intensify the moisture removal process, i.e. the time for producing a solid solution is reduced by 31-56%. The mixture used Fe(NO₃)₃ ·9 H₂O (75%) + NH₂-CH₂-COOH (25%) as a result of synthesis by combustion makes it possible to obtain Fe₂O₃ with Ssp = 12 m2/g. The introduction of additives makes it possible to increase the efficiency of synthesis in the self-propagation mode and increases the specific surface area, but in the case of SiO2, Al₂O₃ it leads to contamination of the product with these components. It was found that the introduction of oxides into the composition allows one to regulate the surface area of the reaction products over a wide range. Input of 5% SiO2 allows you to achieve Ssp = 30-32 m2/g, iron (III) oxide and aluminum oxide leads to an increase in specific surface area to 20-25 m2/g.

Published: November 2024

The production of artificial polymers with a complex of useful physical and chemical properties is based on three main methods of their synthesis is polymerization, polycondensation and modification. At the same time, the modification of polymers has now found wide application, including for the production of cellulose ethers, among which cellulose nitrate ester is one of the large-scale products. Through reactions of functional groups, cellulose nitrate can be converted into new compounds in nucleophilic substitution reactions. The interaction of 4,4',5,5'-Tetranitro-2,2'-bi-1H-imidazole (TNBI) with cellulose nitrate C6H7O2(OH)0,87(ONO2)2,13 in the medium of dimethylformamide at a temperature of 70-72 oC and different reaction times 1, 2, 3 and 4 hours was studied. The main directions of the reaction were identified, namely, nucleophilic substitution nitrate groups of cellulose nitrate for a fragment of a THБИ; partial hydrolysis of nitrate groups; depolymerization and destruction of the polymer chain with the breaking of β-glycosidic bonds and joining at the ends of the polymer chain in the positions C1 and C4 of the fragment of a TNBI molecule. Based on the results of experimental data and physical and chemical studies, the chemical composition and structure of the reaction products obtained are determined and the scheme of interaction of cellulose nitrate with TNBI is presented. It was found that the product of interaction of cellulose nitrate with TNBI, obtained at the maximum reaction time 4 hours at a temperature of 70 oC has the lowest degree of substitution of nitrate groups. A further increase the reaction time does not lead to a significant increase in the content of the TNBI fragment in the products, since there is a strong degradation of the initial polymer, which makes it difficult to isolate high-molecular products was found. The possibility of a directed change in the composition of chemically modified cellulose nitrates at different stages of synthesis to obtain products with controlled composition and properties has been established.

According to the Ministry of Natural Resources and Environment of the Russian Federation, about 70 million tonnes of solid municipal waste are generated annually in Russia, which contain up to 50% of polymer packaging material that has a negative impact on the environment. The amount of waste increases every year by more than 3%, destroying the fragile ecological balance in nature. Along with this there is a problem with utilisation of polymer multi-component wastes, of which there are more than 400 different types, differing from each other by compositions and technologies of processing and utilisation. Recycling of polymer wastes acquires topical importance not only from the point of view of environmental protection, but also due to the fact that in conditions of polymer raw materials deficit plastic wastes become a powerful raw material and energy resource. In order to prevent negative impact on the environment and rational use of natural resources the technology of multi-component aluminium-containing polymer waste recycling has been developed. The technological line was designed and implemented by the limited liability company "ReDevelopment". The initial raw material is complex two-layer blisters from medicines, representing a cellular plate of polymer with glued aluminium foil. In the course of operation of the technological line for processing aluminium-containing polymer waste, two types of products are formed: powder from a mixture of aluminium and polymer waste and powder of plastic waste based on different polymers. Aluminium powder is used to form aluminium briquettes, which are marketable products.

Increasing interest in environmental protection leads to a search new technologies and attempts to revive old technologies for obtaining and processing materials. Environmentally friendly technologies have become more than popular. Currently produced shoes with uppers made of felt and felt satisfy the consumer in design, internal shape, appearance, and some other indicators, however, the issue of increasing the heat-shielding properties of the seams connecting the upper parts is still relevant. One of the disadvantages of the thread method of assembling a shoe upper blank from felt is heat loss through the seams, insufficient strength, and water permeability. Thread-free methods for connecting parts of shoe uppers can eliminate these disadvantages. The object of study was the technological process of gluing parts of shoe uppers made of felt. The subjects of the study are finished shoes and external parts of felt shoe uppers. The advantages of adhesive assembly of felt shoe upper blanks are considered. It is hypothesized that the adhesive assembly method will preserve the heat-protective and strength properties of felt shoes. To assess the bonding strength of parts, felt samples were glued together with a polychloroprene adhesive solution and examined for delamination. To evaluate the modeling of the delamination process, the theory of crack formation and the adhesive separation model were applied. The finite element method was used to simulate the dynamics of separation of one surface from another. The conducted studies and calculations have proven that when felt samples delaminate, the stress is concentrated in the vicinity of the tear-off point, and then gradually decreases in sections of the tear-off length, where the adhesive resistance force ceases to act. The results of modeling the delamination process were used to predict the behavior of adhesives during the operation of felt shoes under different conditions.

Trunk pipeline transportation is the most important component of fuel and energy complex of Russia. In accordance with the regulations, control of equipment operation, compliance with labor protection and industrial safety requirements at production facilities as high-risk areas is carried out. Based on the results of monitoring the operation of road construction equipment, it was established that the majority of violations occur in the operation of video recording equipment. To optimize the process of managing video information, the authors have developed a software package (PC) using artificial intelligence methods for digital processing of video content, which allows analyzing data received from video recorders. The software product is designed to automate the process of processing video data: identifying violations in the operation of video recording; operational control and analysis of performance indicators of the DVR; creating a database with identified violations; generating operational, reliable information online from construction equipment. The developed computer program examines video analytics scenarios that make it possible to automate the processing of video materials: defocus or contamination of the video camera lens (cloudy, unclear image, dirty or obscured camera lens); disconnecting the video camera from the DVR (recording is in progress, a black or blue screen is recorded with time stamps on the video); lack of movement (recording of “garbage” video without production of work, no movement, picture does not change); interference when recording video (stripes, strong video jerking, video “scattering” into rectangular segments). The software package consists of 3 main modules, each of which has its own functionality for a comprehensive solution to the task. The use of a software package allows you to identify violations in the operation of video surveillance equipment. Automated analysis of video information is considered as a resource for increasing the efficiency of management and safe operation of special equipment. Using video analysis systems, you can obtain valuable information about the quality of work of company personnel at remote sites, which allows for a more adequate assessment of their work, as well as checking compliance with safety standards at high-risk sites.

The paper considers the problem of recognising road infrastructure elements (temporary signs, guardrail tapes, traffic cones). To solve it, we propose to use the following types of models: Deep Learning model, Random Forest model, Support Vector Machines model, Directional Gradient Histogram model. The principles of operation of the models presented in the article are considered. Recognizing road infrastructure elements in three of the four models studied requires a significant amount of time. The factors influencing the implementation of road works and object recognition are analyzed. The need for road work often depends on weather conditions (rain, snowfall, blizzard, fog, etc.). Recognition of road infrastructure elements includes the following stages: data capture, data preprocessing, model selection, model training, model testing. The article proposes the choice of a recognition model for road infrastructure elements (temporary barriers, temporary signs, traffic cones) based on the YOLO neural network, which has high detection speed and accuracy. The use of the YOLO neural network model allows for timely recognition of objects in images or video streams, which will further reduce the risks of road accidents. Based on the analysis of recognition models for road infrastructure elements, the use of the YOLO neural network model, which does not require significant financial costs, is proposed. The model was trained in the Google Colab development environment in the Python programming language. The neural network model was trained for 100 epochs in 15 minutes. The accuracy of recognition of road infrastructure elements on the training data set was 90%, and on the test set - 79%. In the future, it is planned to expand new data in the form of images of road infrastructure elements and develop a software package for automatically recognizing these elements and reducing the number of road accidents.

Regardless of cultural or geographical contexts, women worldwide often bear the primary responsibility for childcare and household management. For women pursuing careers, these responsibilities are amplified, creating a challenging dynamic as they strive to balance professional duties with domestic obligations. The onset of COVID-19 profoundly disrupted lives, with working women being particularly impacted. The pandemic necessitated a rapid transition to a "new normal," where remote work became the standard. This shift required women to juggle childcare, household chores, and professional tasks within the confines of the same physical space. Work-life balance refers to the equilibrium between personal, family, and professional responsibilities, while resilience is defined as an individual's capacity to cope with and recover from adversity. This paper examines the psychosocial factors contributing to work-life balance and resilience, which are vital for achieving a balanced and fulfilling life among working women in Malaysia. Data was collected through a qualitative approach using focus group discussions with eleven working women from diverse professional backgrounds, and the data was analyzed using thematic analysis. The findings reveal that the psychosocial factors affecting work-life balance and resilience are deeply interconnected. Three major themes emerged from the analysis: social support, individual factors, and spirituality. These factors enable working women to adapt, persevere, and thrive despite challenges, especially with the support of their families, including spouses and parents. This study underscores the critical role of psychosocial factors in enhancing work-life balance and resilience among working women, highlighting their importance in navigating the complexities of modern life.

This study examined the effect of crop insurance on the financial risk of smallholder rice farmers in the grass field of Cameroon. Panel data from 76 Smallholder rice farming groups from 2019-2022 was used, while the Panel-corrected standard error technique was used for estimation. The results revealed that crop insurance captured using inputs (fertilizers, herbicides, and treated seeds) and land preparation had a positive and statistically significant effect on financial risk. These results validate the risk balancing hypothesis for smallholder rice farmers. Control variables like Farm size and labour had a positive and statistically significant effect, while training cost and buying price had a negative and statistically significant effect on financial risk. The results therefore, indicate that smallholder rice farmers need to adopt crop insurance practices such as use of quality farm inputs and better land preparation techniques in order to manage financial risk.
