Evaluation of the strength characteristics of polymer materials for the manufacture of personal electric vehicle elements
Authors: Yankevich S. N. , Khrol I. N. , Kalinovskij N. A.
Published: April 2023

The properties of materials for airless wheel propulsion of vehicles, including electric ones, have been studied. The experimental substantiation of the choice of the type of polymer matrices and compositions of reinforcing fillers for the manufacture of an airless wheel mover of electric vehicles has been carried out. To test the basic epoxy matrix, part of the samples without the addition of reinforcing fibers was cured at room temperature (L-285H), and the rest (L-285G) – when heated to 60 °C. In order to improve the strength characteristics of the epoxy matrix L-285G, glass reinforcement was carried out with EC16 1600T-16(400) glass reinforcement. The Smooth-Cast 300 Series was chosen as the matrix for performing samples based on injection-molded polyurethanes. Samples are made of base polyurethane under various conditions: at atmospheric rejection (SC), under vacuum 0.8 kPa (SC-0.8) and during vibration-induced curing (SCV). Comparative tests were carried out, which showed differences in the mechanical properties of the base matrices based on epoxy resins and injection-molded polyurethanes, in particular, the relative elongation of samples from injection-molded polyurethane by more than 2 times. It is established that the most rational use of injection-molded polyurethane is application as damping elements, and the material for manufacturing spokes dampers is composite SCV-S-20. It is advisable to manufacture products from the resulting composite when vibrations are applied to the mold and with preliminary vacuuming at a vacuum of 0.8 kPa of the components of the polyurethane matrix, which reduces the number of internal defects in the form of shells. Since vacuuming of the product during polymerization does not give a significant effect due to the presence of a set of specialized deaeration additives in the base matrix, it is proposed to carry it out under constant control, since exceeding the vacuum in the range from 0.8 to 0.9 kPa entails decomposition of individual matrix components with foam formation.

Using a methodical approach to the potential biological hazard (radiotoxicity) assessment of radionuclides, computational studies and a comparative analysis of the contributions to the total radiotoxicity of long-lived fission products and actinides accumulated in the nuclear fuel cycle of the Belarusian NPP were carried out. In order to estimate correctly the 237Np isotope mass at the long-term stage of SNF management, the mathematical model of the nuclear fuel cycle of the Belarusian NPP of the code CUB was modified to take into account the transmutation chain of 241Pu, 241Am and 237Np isotopes. The initial concentrations for the main radiation-hazardous radionuclides at the time of fuel unloading from the VVER1200 reactor core are presented in the database “Radiation Characteristics of Spent Nuclear Fuel of the Belarusian NPP” developed by the authors. The database development is carried out in accordance with the recommendations of the RB-093-20 “Radiation and thermophysical characteristics of spent nuclear fuel of pressurized water power reactors and high-power channel reactors”. The main characteristics used in the nuclear fuel cycle simulation in the CUB code, such as the total mass of spent nuclear fuel (2492 tons), the number of spent fuel assemblies (5294) and the average burnup, are taken in accordance with the Spent Fuel Management Strategy of the Belarusian NPP data. It is shown that at the stage up to 100 years, the main contributors to the total radiotoxicity are the isotopes of 238Pu, 239Pu, 240Pu, 243Am, 241Pu, 241Am, 237Np, where contributions of three last of them are 0.07, 49.0 and 0.007%, respectively. But 5000 years later, the contribution of 241Am will be 0.24%, and the isotope 237Np – up to 0.1% of the total actinides radiotoxicity. The results obtained can be used to substantiate for the recovery degree requirements of 237Np, 241Pu, 241Am during the SNF of the Belarusian NPP reprocessing.

Published: April 2023

The results of a study on the choice of the optimal measurement geometry, measuring capacity and method of sealing the measuring capacity for determining the concentration of radon-222 in samples of mineral radon water are presented. Studies of radon water samples were carried out in laboratory conditions on a stationary gamma spectrometer based on a semiconductor Ge(Li) detector. The concentration measurements in the samples were carried out in accordance with MVI. MN 3421-2010 “Methodology for measuring the volumetric and concentration of gamma-emitting radionuclides on gamma spectrometers with semiconductor detectors” for standard plastic vessels “Denta, 0.1 l” and “Marinelli, 1 l”, and glass containers with a volume of 0.5 l with lids for twisting and seaming. The results of the research showed that the leakage of radon from a glass container with a metal lid for sealing is minimal. This method of sampling and sealing the measuring vessel makes it possible to increase the accuracy of the presented measurement results by reducing the corrections for sample preparation when calculating the expanded measurement uncertainty. A glass container with a volume of 0.5 l with a metal cap for seaming was used to measure the concentration of radon in samples of mineral radon water taken from wells and a drinking fountain of the Radon sanatorium of Belagrozdravnitsa JSC (Dyatlovo District, Grodno Region). The concentration range was 760–2100 Bq/kg. The selected measuring container, the method of its sealing and the measurement geometry can be used for future measurements of the radon concentration in samples of mineral radon water taken in the sanatoriums of the Republic of Belarus.

Non-edible oils are not used as food, which comes from plants that are not used properly, but are very abundant and even become waste. These plants are able to produce high enough oil, which is around 30-80% with a composition that is almost similar to edible. The oil can be obtained by extraction. However, most people do not know how to extract these oils. Therefore, it is necessary to introduce and train on how to extract these non-edible oils, especially people who have the potential to be young entrepreneurs, one of which is SMK. SMKPP Negeri Mataram is one of the secondary schools that carries out the mission of education in the field of agriculture extensively and prepares capable and skilled human resources in agriculture. This service aims to increase the knowledge and understanding of SMKPP Negeri Mataram students about local plants that have the potential as non-edible and oil extraction training which can later become the provision of students after graduation by taking advantage of the potential and opportunities that exist around them. This service activity will be carried out in two stages, namely introduction/socialization activities about plants that have the potential as non-edible and simple oil extraction training. The results of service activities have provided additional knowledge and understanding of SMKPP Negeri Mataram students about local plants that have the potential to produce non-edible oil and simple oil extraction techniques.

TBI is mechanically followed by pathomechanisms that cause damage to surrounding neurons, such as cell and tissue necrosis, inflammation, cerebral edema, breakdown of the blood-brain barrier, and hyperthermia. The more severe the brain injury, the greater the impact on the inflammatory response. Therefore, this study aims to determine the histopathological description of edema in rat brain cells after TBI and to analyze the relationship between differences in trauma burden and histopathological features of brain cell inflammation, hematoma, and edema in mice after traumatic brain injury. This study uses an experimental observational-analytical research design. Sprague-Dawley mice were used as research subjects and divided into four cluster groups (and one control group) with varying trauma-loading interventions. The trauma loads given were 20 grams, 40 grams, 60 grams, and 80 grams. Following the trauma load application, the mice's brains were biopsied one hour after the intervention to observe histopathological features of inflammatory markers (synaptophysin) and brain cell edema. The data were then analyzed using the SPSS program. Twenty mice were included in this study. The results of the study showed that there was a mean load of 50 grams, and there is a mean synaptophysin percentage of 23.5%. There was a significant relationship between differences in trauma load and the percentage of post-TBI rat brain cell edema (p <0.001). There is a perfect and strong correlation between differences in trauma load and the percentage of synaptophysin (p=0.926). It was discovered that as the trauma load increased, there was a growing percentage of edema and inflammation in the histopathological features of the mice’s brains. There was a significant difference between the severity of trauma and the percentage of brain cell inflammation and edema one hour after brain injury in mice. The more severe the level of trauma given, the higher the percentage of inflammation and edema that occurs in rat brain cells. The result is especially notable since the inflammation and edema is found one hour within injury.
Pengembalian Keuntungan Tidak Sah Terhadap Investor Ritel : Keadilan Korektif Melalui Konsep Disgorgement
Authors: Mentari Nikmah
Published: April 2023

Semakin canggih suatu teknologi tidak menafikan adanya pelanggaran maupun kecurangan di pasar modal. Hal ini tentu saja banyak menimbulkan kerugian secara materiil, sehingga dapat mempengaruhi krisis kepercayaan masyarakat dalam berinvestasi di pasar modal. Terlebih, keberadaan UU Pasar Modal yang cukup lama belum memenuhi keadilan bagi investor sebagai salah subyek hukum. Adanya pelanggaran masih berfokus pada pembebanan sanksi bagi pelaku, sedangkan kondisi atau kerugian investor kerap kali diabaikan. Bagi korban kerugian pelanggaran, khususnya investor ritel, yang paling dibutuhkan ialah pengembalian dana yang telah diinvestasikan. Oleh karena itu, Otoritas Jasa Keuangan melalui POJK tentang pengembalian keuntungan tidak sah dan dana kompensasi diharapkan menjadi harapan baru bagi perlindungan investor ritel. Konsep tersebut mengadopsi Securities Exchange Commission Amerika Serikat tentang pembayaran disgorgement. Penelitian ini bertujuan untuk mengkaji pengembalian keuntungan tidaksah terhadap investor ritel akibat pelanggaran berdasarkan aturan OJK dan dalam perspektif keadilan korektif melalui konsep disgorgement. Penelitian ini merupakan penelitian hukum normative yuridis. Dalam perkembangannya, disgorgement diharapkan selain memberi perlindungan bagi investor di pasar modal, juga dapat terpenuhinya keadilan korektif bagi perkembangan hukum pasar modal di Indonesia.

Published: April 2023

Central venous catheter fracture and migration are rare complications in patients receiving long-term infusions or chemotherapy. We present a rare case of a chest port catheter fracture that migrated into the coronary sinus. This case is likely the fourth report of a port catheter fracture with migration to the coronary sinus. Because of the difficult-to-retrieve location, multiple attempts were unsuccessful with traditional techniques using a loop snare. Finally, the fractured portion was disengaged from the coronary sinus using a navigational electrophysiology catheter guided by intracardiac echocardiography; the dislodged end was snared and eventually removed by the femoral route. This case of a chest port catheter fracture is unique because of the unusual migration to the coronary sinus and the use of a navigational electrophysiology catheter as a novel retrieval technique.

Este trabalho avaliou retrospectivamente correções de imagens planares de pacientes já submetidos a tratamentos de neuroeixo, a fim de quantificar a magnitude dos erros de posicionamento e aplicá-los em diferentes técnicas de radioterapia em arco modulada volumetricamente (VMAT) para definir a que possui o menor impacto dosimétrico considerando estes erros, para implementação na prática clínica, que é objetivo deste estudo. Ao todo 219 imagens planares de 15 pacientes foram selecionadas para avaliação estatística de erros de posicionamento. Para os planejamentos, quatro pacientes pediátricos já tratados com técnica 3D conformacional foram selecionados. Para cada um, cinco planos de tratamento VMAT foram otimizados em duas técnicas: sobreposição com 3 cm, 6 cm e 9 cm de junção e gradiente com 6 cm e 9 cm e foram avaliados pelos índices: V100%, V95%, D98%, D2%, número de conformidade (CN) e índice de heterogeneidade (HI). Em cada plano, foram inseridos erros de posicionamento com a magnitude encontrada na análise retrospectiva das imagens, bem como avaliar a diferença na distribuição de dose quando considerado a mesa de tratamento. As imagens demonstraram deslocamentos médios entre 1 e 5 mm e em alguns casos chegando à 15 mm. Em relação à qualidade dos planejamentos, todos obtiveram resultados coerentes baseados nas métricas avaliadas sem diferenças significativas. Porém, a técnica de gradiente (9 cm de junção) reduziu o impacto dosimétrico em comparação às outras técnicas quando submetida aos erros de posicionamento. Por fim, ao considerar a mesa de tratamento nos planejamentos, foi encontrada uma redução de 10% no V100%. Os resultados mostraram que para implementação da técnica VMAT para neuroeixo recomenda-se realizar imagem de posicionamento diária para minimizar erros de posicionamento com magnitudes maiores que a média encontrada de 3 mm no sentido longitudinal, pois estes têm impacto significativo na distribuição de dose nos planejamentos modulados.

FORMS OF PROTEST IN LATVIA DURING THE PANDEMIC VERSUS THE ACTIVITY OF THE POLICE
Authors: Marszałek-Kawa Joanna
Published: April 2023

The COVID-19 pandemic, which broke out on an unprecedented scale in 2020, forced the public authorities to impose a series of restrictions and limitations on constitutional rights and freedoms, which provoked strong reactions, particularly in the democratic world, and encouraged social unrest. The speed of the measures, their scope and the degree of negligence, which undoubtedly affected the lives of millions of people, strengthened social resistance. The research problem in this paper concerns the influence of the pandemic-related restrictions introduced in Latvia on the mobilisation and demobilisation of demonstrators and the evaluation of the methods used by the Latvian police in the conditions of civil disorder caused by these restrictions. The aim of this paper is to examine the violent acts committed by the demonstrators and the forms of protest they used, as well as to analyse the actions of the officers of the services responsible for securing the demonstrations. The author sought answers to two main research questions: What actions did demonstrators take during the pandemic in Latvia? How did the security services ensure the safety of the demonstrations and what methods did they use? The study used institutional and legal analysis as well as qualitative source analysis. It also used the method of content analysis, mainly of messages and announcements related to the behaviour of protesters and law enforcement agencies during the period in question.

Published: April 2023

The article deals with the problems of development of printing enterprises in Ukraine in the conditions of uncertainty connected with military operations (destruction of enterprises, problems with supply of imported raw materials, logistic obstacles, risks of shelling, power cuts, etc.). The study points out the dependence of the printing industry on the import of raw materials and the dependence on customer enterprises, many of which ceased to operate after the start of a full-scale invasion of Ukraine. It is proved that the producers of printing products are forced to adapt to modern realities in conditions of uncertainty. A list of necessary factors that will create an additional impetus for the development of enterprises is presented. The relationship between such components as new sales markets, availability of resources, efficiency of material and technical support, enterprise development is described in detail. It is proposed to examine the possibility of using the theory of strategic games as a direction for optimizing the configuration of printing enterprises with material reserves. It is established that the development of the printing market is determined by the development of the industries consuming printing services. This proves the intensification of the struggle for sales markets. Since printing is a material-intensive industry, it is relevant to take into account modern challenges. To solve the problem of enterprise development it is proposed to use the theory of strategic games. On the basis of the calculation of possible strategic options it is determined which strategy should be chosen for the printing enterprise. The possibilities of the development of conditions for the optimization of the equipment of printing houses with material reserves using the theory of strategic games are shown.

Published: April 2023

The purpose of the article is to define the de-shadowing of the economy in the sphere of non-bank financial institutions. The author presents the peculiarities of the domestic shadow economy and defines the concept of the shadow economy in the non-banking financial sector, identifies the components of the shadow economy, and proposes measures to overcome shadow economic processes. Subject of the research – de-shadowing economy in the sphere of activities of non-banking financial institutions. The shadow economy in the NFI is a complex socio-economic phenomenon, which is presented as a set of uncontrolled and unregulated, both illegal and legal, but immoral financial and economic relations in the sphere of activity of the NFI, which are in conflict with the legislation in force and are characterised by deliberate illegal acts of individuals, committed with the aim of concealing their income from the state and its bodies, making profits, evading taxes, etc. The shadow economy has three components: the informal, the hidden and the underground (criminal) economy. The informal economy is characterised by unregulated production of goods and provision of services; the hidden economy is the legal production and sale of unregistered goods and services; the underground (criminal) economy – prohibited activities (corruption, drug trafficking, etc.). Methodology – the article uses general scientific methods of formal logic (analysis, synthesis, deduction, induction, analogy, abstraction and modeling). It should be noted that the content analysis method made it possible to determine the influence of the shadow economy on the commission of violations in the field of activity of NFIs, to show in a qualitative and quantitative ratio, in general, the trends in the level of spread of violations in their activities. Results. The definition of the concept of the shadow economy in the non-banking financial sphere is given – it is a complex socio-economic phenomenon, which is a set of uncontrolled and unregulated, both illegal and legal, but immoral financial and economic relations in the sphere of activity of NFIs, which are in conflict with the legislation in force and are characterised by deliberate illegal actions of persons with the purpose of concealing their income from the state and its bodies, making profits, evading taxes, etc.; the components of the shadow economy are defined; it has been proved that Ukraine has a fairly extensive shadow economy in its economy, which actually serves as the basis of the country's entire financial policy. The NBU acts as a state regulator of social relations arising during the conduct of economic activities related to finance (public or private).
Review of the security challenges in web-based systems
Authors: Odiaga Gloria Awuor
Published: April 2023

Web-based systems are vulnerable to security issues similar to any other applications. Due to the characteristics of web-based systems such as their distributable nature and cross platform accessibility, security challenges are predominant. Recently, more focus has been placed on how to handle security concerns in web systems. Current solutions to counteract the web-based system security challenges include web system languages, firewalls, Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), cryptographic techniques, digital certificates and signatures among others. However, attacks and threats such as cross site scripting (XSS), Distributed Denial of Service (DDoS), cross-site request forgery (CSRF) and structured query language (SQL) injection attacks are still common. This gives the impression that there are still security challenges in this regard, despite the efforts for detection and prevention of attacks. Consequently, due to their dynamism, secure architectures are pivotal for the security of web-based systems. The focus of this paper therefore, is to review the existing security challenges of web-based systems. It is evident from this literature study that most security challenges in web-based systems stem from the threat of unauthorized access and risks from implementing technologies and standards that are under developed as regards security.

Population density and spread of COVID-19 in Bandung City, Indonesia
Authors: Syafriharti R
Published: April 2023

Population density is an important factor for a sustainable city. However, it turns out that population density is also a problem in cases of the spread of COVID-19 in several countries, although there are other factors that also play a role. This paper aims to prove how population density affects the spread of COVID-19 in Bandung City with the sub-district data unit. To obtain a complete overview, the analysis was carried out by comparing conditions at the weekend as usual with the conditions during the long weekend. Simple regression analysis was used to determine how population density affects COVID-19 cases. A comparative analysis was then carried out to compare the effect of population density on the number of COVID-19 cases in the two different weekend conditions. The analysis found that population density did affect the number of COVID-19 cases, but this did not apply to all sub-districts. Population density has a greater effect on COVID-19 cases during the usual weekend than during the long weekend. In addition, the best model during the normal weekend only applies to 21 sub-districts, while the best model during the long weekend applies to 26 sub-districts. With these findings, urban planners need an in-depth study of the appropriate concept of population density for a compact and sustainable city.
