Authors: Darmawan  , Lovelyson  , Meifal Rusli  , Rahmadi Kurnia  , Amirul Luthfi
Published: December 2024

Semi-active dampers reduce the effects of shock vibrations because they can operate at specific vibration frequencies at a lower cost than more complex active dampers.  PSMEID is one of the alternative methods developed in the semi-active damping system. PSMEID has been developed by adapting it by adding a PSMEID active time prediction system when an impact occurs. This research attempts to compare two types of PSMEID with active time prediction, where the position of each model offered has a different PSMEID mass position when applied to the landing gear damper of an Unmanned Aerial Vehicle (UAV). This comparison aims to give the user a choice among these optimal models suitable for use in multiple conditions. When simulated using the same parameter values, the PSMEID placed on the unsprung mass can reduce acceleration amplitude by up to 6.6 percent when the landing gear is dropped at 0.15 meters from the ground. The model that places the PSMEID on the sprung mass can help reduce the velocity amplitude up to 8.8 percent when dropped at a height of 0.05 meters, and the spring constant value of the PSMEID (KPS) is 1600 N/m. All these simulations show that the PSMEID should be activated just before the landing gear hits the runway surface (TB < TL).

Authors: Ayu Elsa Afriyanti  , Muhammad Imran Hamid  , Anna Cyntia Pahsa De Yudanur  , Niko Saputra
Published: December 2024

The need for electrical energy is changing and increasing, requiring system flexibility always to be changed and developed. On the other hand, changes in the configuration of the electric power system due to the addition of components or sub-systems also change system parameters such as impedance or level of fault current (short circuit current). This paper presents a study of changes in the fault current caused by adding a new generating bus to an electric power system. This paper aims to determine the change in short-circuit current due to the addition of generators on new buses connected to existing buses to identify the most suitable location for adding these generators based on short-circuit current levels. Three-phase short circuit faults are simulated and analyzed on the IEEE 14 bus standard system using ETAP software with a base MVA 615 MVA. The addition of generators was carried out at five locations with varying generating capacities. The research results show that the short circuit current will change significantly when adding a generator bus to bus 13, with an average percentage change of 5,656%. The smallest change occurs when adding a generator to bus 2, with an average percentage change of 2,417%. The research results conclude that connecting a generator to a new bus linked to an existing generator bus (PV bus) is more effective than connecting it to a new bus associated with a load bus (PQ bus).

Published: December 2024

As neoplasias cutâneas em cães, como histiocitomas, são comuns e geralmente aparecem na derme e tecido subcutâneo, mas podem ocorrer em outras áreas. O prognóstico e o tratamento dependem do grau histológico do tumor, com a ressecção cirúrgica sendo a mais eficaz. Nesse contexto, este trabalho teve como objetivo relatar um caso de exérese de tumor sugestivo de histiocitoma na região do cotovelo de um cão, macho, da raça Fila Brasileiro, que pesava 45 kg. Dessa forma, foi realizada uma avaliação clínica e exame físico, no qual o paciente apresentava sensibilidade à palpação na região do tumor. Além disso, realizaram-se exames complementares, a exemplo de hemograma, eletrocardiograma, bioquímica sérica, citologia e histologia. De acordo com esses exames realizados, foi constatado que o paciente precisaria de intervenção cirúrgica para a exérese da neoplasia. A abordagem cirúrgica foi feita executando-se uma incisão de forma elíptica com pouca margem de segurança. Em seguida, realizou-se a divulsão do tecido subcutâneo, que aderia a neoplasia à musculatura, e a remoção do tumor. A abolição de espaço morto foi realizada com fio de sutura Catgut de espessura zero e padrão de sutura simples contínuo. Após isso, fez-se a dermorrafia com fio de sutura Polipropileno de espessura zero e padrão de sutura Wolff com capton de equipo de soro fisiológico. Conclui-se que o tratamento cirúrgico foi eficaz, visto que o animal não precisou realizar o procedimento novamente.

Authors: Silva Renan Francelino , Silva Rafael Cândido , Oliveira Camila , Gomes Neto José Mário
Published: December 2024

What does influence the issuance of Preliminary Injunctions (in limine) in Writs of Mandamus within the jurisdiction of Pernambuco's Federal Court? To protect citizens against abuse of power or illegality committed by a member of the Public Administration, the Federal Constitution provides the writ of mandamus as a procedural instrument (section 5, subsection LXIX and LXX, of the Brazilian Federal Constitution, and the Law No. 12.016/09). Existing literature in the fields of procedure law and administrative law highlights the potential conflicts and violations of clear and indisputable rights that can arise from the improper granting or denial of preliminary injunctions. This article aims to empirically examine, through logistic regression analysis (logit), the factors that influence the issuance of Preliminary Injunctions (in limine) in Writs of Mandamus within the jurisdiction of Pernambuco's Federal Court.

Authors: Almaududi Almaududi
Published: December 2024

Family-owned companies have a significant role in enhancing national competitiveness. However, conflicts that lead to court disputes threaten the sustainability of family-owned companies. It has happened because some decisions still need to provide legal certainty. This research analyzes the legal aspect of family-owned companies in Indonesia, as reflected in several court decisions in Indonesia. The research method employs a qualitative case study approach. The research findings identify the existence of family-owned companies in court decisions; however, there are some difficulties, such as in determining the legal standing of disputing parties, potentially detrimental provisional decisions, and complexities in understanding corporate law, especially regarding General Meetings of Shareholders (GMS), dividends, and inter-organizational relationships as well as internal family disputes. The findings highlight the need for courts to consider the unique characteristics of family-owned companies, which could improve the consistency of court decisions, enhance legal certainty in the business sector, and promote sustainable economic activities.

Published: December 2024

Dynamics of economic relations development among Russia and African countries in the beginning of the 21st century has been analyzed. At that time there was the economic relations strengthening among Russia and African countries, which was caused by several factors: 1) the interest of Russian companies in the resource potential of Africa; 2) the support of the Government of the Russian Federation for the export of goods and services to African countries; 3) the growth of trade among Russia and African countries; 4) the increase in investments of Russian companies in African countries. At the beginning of the 21st century, Russia and African countries strengthened their cooperation in the economic sphere. It had a positive impact on both sides, contributing to African countries development and Russian companies’ expansion in this market, and strengthening regional stability. Acting on the dual front of bilateral diplomacy and multilateralism, Russia, through the BRICS forum, must ﬁnd its place on the continent. Central Africa has strengthened its economic relations with China, India, and Brazil while developing its own activities on the continent.

Published: December 2024

The key changes observed in modern international trade in agricultural products have been analyzed from the position of assessing the challenges faced by agricultural markets in recent years. The features of the agro-industrial products international trade evolution have been considered, the main trends and changes in global production and consumption have been assessed, and medium-term development prospects have been deﬁned. The world land fund transformation due to international trade development, which has become signiﬁcantly diversiﬁed, has been shown, and the preservation of differentiation among net exporters and net importers of agricultural products has been noted. The changes in the world production and consumption of agricultural commodities formulated in the course of the study have become the key trigger for modernization of the global architecture of international trade. It has been shown that it will remain a key factor in the further development of agricultural production, but the process achieved in exports and imports liberalization is signiﬁcant in terms of ensuring food security of the least developed importing countries. It has also been found that world agricultural commodity prices will stabilize in the medium term, which is an important factor in the food security of developing countries.
Economic efficiency of energy storage systems for renewable energy power plants integration in the energy system
Authors: Tregubova E. A. , Gorodilov M. A. , Lyushnin L. S.
Published: December 2024

The features of the main ﬂexibility mechanisms, limitations to their application, and price characteristics have been considered. The advantages of equipping RES-based generation with energy storage devices have been noted. Investment and operating costs of a storage device for 60 kW capacity and their ratio with the corresponding costs of solar power plants have been analyzed. On the basis of model calculations, the change in the levelized cost of electricity (LCOE) when a solar power plant is supplemented with a storage device has been estimated. It has been shown that equipping a solar power plant with an accumulator, despite high capital costs, will lead to an increase in the electricity cost on average for the entire period of operation by only 3–17 % due to the expected increase in utilization and volume of electricity production, as well as the projected decrease in the cost of accumulators. At the same time, a signiﬁcant increase in the energy system stability will be ensured. It has been noted that it is necessary to tighten the requirements for the installed capacity utilization rates of power plants and to give priority to projects with storage facilities in the competitive selection of RES generation under capacity supply contract programs.

Published: December 2024

The purpose of the study is to examine the role and importance of this tax when forming revenues of consolidated budgets of the constituent entities of the Russian Federation in the context of federal districts, and its impact on the formation of indicators characterizing the social sphere, as well as to analyze the positive foreign experience of personal income taxation. The general scientiﬁc methods of cognition (analysis, synthesis, generalization, grouping, comparison, tabular, etc.) were used. The study is based on ofﬁcial data of the Federal State Statistics Service and the Federal Tax Service of the Russian Federation. It has been established that personal income tax fulﬁlls its ﬁscal function, and it is the main source of income of local budgets and regions. As for the social function, it is currently lost. It is reﬂected in the following: in four federal districts, where about half of the country’s population lives, wages are below the average Russian level; the coefﬁcients of funds and Gini coefﬁcient are not improving; deductions and beneﬁts on personal income tax do not fulﬁll the social function, social justice is not ensured, and social stratiﬁcation of society is increasing. In the context of the current unfavorable demographic situation and external challenges due to Western sanctions, it is necessary to strengthen motivation to work, considering foreign positive experience to introduce a real and workable progressive scale of personal income taxation.
Professional motivation as a factor in emotional burnout of chess coaches and teachers
Authors: Umanskaya E. E.
Published: December 2024

The purpose of the study is to reveal the relationship between certain motives of professional activity of chess coaches and the level of their emotional and professional burnout. On the basis of the theoretical analysis results it has been suggested that professional motivation of coaches, which is based on the desire to achieve high sports results of their students, in the absence of such results is one of the dominant factors of the growing latent emotional tension and dissatisfaction with their professional activity. Veriﬁcation of the put forward hypothesis was carried out on the research sample of 118 coaches and teachers, whose experience of professional activity in chess sections and clubs was from two to 30 years. The research was carried out with the help of methods oriented on revealing the needs and motives of professional activity, as well as accumulated emotional-energetic charges and professional burnout. It has been revealed that the majority of chess coaches and teachers are focused on achieving high sports results of their students, but not on their general mental and intellectual development, that in the absence of such results workers have latent emotional tension, which leads to emergence and development of professional deformations of their personality, devaluation of their professional activity, and tendency to underestimate the importance of their work. In order to achieve the priority goals of chess education development in Russia it is necessary to reorient chess coaches from the position of the value of competitive results to the value of their students’ development.

Comparative review of allowances types for dividing a benefit with indivisible items
Authors: Egorov V. V.
Published: December 2024

The article studies the issues related to the problem of sharing by two beneﬁciaries of a resource with a set of indivisible components. Several types of sharing that consider “envy” and realize it, including through compensatory payments to the beneﬁciary who does not get the corresponding indivisible component of the resource, have been noted. The difference between the values of possible bonuses at different types of sharing, which are received in addition to the values declared by the beneﬁciaries, and indivisible components when they are evaluated, has been determined. It has been found in which case it is more favorable for the beneﬁciary if “envy” is not considered, and vice versa. The method of setting the degree of preference of considering “envy” in the course of distribution of resource components has been proposed, assuming a preliminary agreement of beneﬁciaries on the use of this method. The result of using it has been analyzed, based on which recommendations to the beneﬁciaries are formulated, implying additional awareness not covered in the present study. In order to circumvent the issue of uninformedness, indications of one option of its solution have been presented, which can be considered also as possible future directions of research of stochastic nature.
Resolution of selectivity steps of CO reduction reaction on copper by quantum Monte Carlo
Authors: Fanta Roman , Bajdich Michal
Published: December 2024

Electrochemical reduction of carbon monoxide to valuable fuels and chemicals on copper surfaces remains a challenging area in catalysis due to a limited understanding of adsorption mechanisms and reaction pathways. Although density functional theory (DFT) based studies have investigated these processes, their accuracy varies across different functionals. Here, we present the first application of fixed-node diffusion Monte Carlo (FNDMC) to benchmark the adsorption energies of CO*, H*, and key CO reduction reaction (CORR) intermediates, COH* and CHO* on the Cu(111) surface. Our results for CO* and H* adsorption energies closely align with experimentally measured chemisorption reactions, highlighting the limitations of DFT, and providing site-specific energy comparisons that are often not available experimentally. Additionally, we explore the effect of explicit solvation, demonstrating how water stabilizes the COH* over CHO*, thus suggesting a critical role of COH* in CORR. Finally, we release our high-accuracy FNDMC benchmarks for testing and developing new DFT functionals for electrocatalysis. Overall, this study underscores the potential of FNDMC for detailed surface chemistry studies and offers new insights into catalytic processes.

Continuous flow in microchannels play pivotal roles in advancing automated chemical synthesis. However, frequent multiphase reactions pose key challenges for designing reactors that efficiently disperse phases. Although effort has been directed toward automating development processes, the unique nature of each existing study offers limited opportunities for generalization; consequently applying this knowledge to new microreactor designs is difficult. In this study, we introduce a self-optimizing workflow that uses large language models (LLMs) to extract key microreactor-system parameters, such as density, velocity, and Capillary number, from the literature. Minimal training led to a reduction in extraction time from 24 to 16 s, with the collected data processed by ensemble learning models delivering F1 scores greater than 70% when classifying flow patterns. Through interpretability analysis, we confirmed the machine learning model's alignment with human expertise. We then applied the model to an oil-water dispersion system for controlled alumina microsphere preparation and a piperacillin synthesis system, achieving accuracy rates of 83% and 94%, respectively. This study offers synthetic chemists an LLM-based tool for the development of microreactor systems, thereby pioneering the use of machine learning in literature-sparse fields.
Molecular simulation study of all-silica zeolites for the adsorptive removal of airborne chloroethenes
Authors: Fischer Michael
Published: December 2024

Chloroethenes are produced and consumed in various industrial processes. As the release of these compounds into air, water, and soils can pose significant risks to human health and the environment, different techniques have been exploited to prevent or remediate chloroethene pollution. Although several previous experimental and computational studies investigated the removal of chloroethenes using zeolite adsorbents, their structural diversity in terms of pore size and pore topology has hardly been explored so far. In this work, molecular simulations using validated empirical force field parameters were used to study the gas-phase adsorption of chloroethenes in 16 structurally distinct zeolite frameworks. As all these frameworks are synthetically accessible in high-silica form, the simulations used purely siliceous zeolite models. In the most relevant concentration range (0.1 to 10 ppm by volume), substantial uptakes of tri- and tetrachloroethene were computed for several zeolite frameworks, prominently EUO, IFR, MTW, MOR, and BEA. In contrast, vinyl chloride uptakes were always too low to be of practical relevance for adsorptive removal. For selected frameworks, simulation snapshots were analyzed to investigate the impact of pore shape and, at higher uptakes, guest-guest interactions on the adsorption behavior. Hence, this study not only identifies zeolites that should be prioritized in future investigations, but also contributes to the microscopic understanding of chloroethene adsorption in crystalline microporous materials.
Autoimmune and iodine deficiency diseases of the thyroid gland as the "tip of the iceberg" of multiple organ pathology
Authors: Troshina Ekaterina A.
Published: December 2024

The article presents modern data on the etiology, pathogenesis, diagnosis and treatment of autoimmune and iodine deficiency diseases in the context of possible associations with other autoimmune and non-autoimmune somatic pathologies. Diseases of the thyroid gland (TG) are presented in the form of a “signal pathology” that requires the attention of doctors; the issues of the syndrome of multiple autoimmune lesions are considered, an obligatory component of which is a disease of the TG, most often autoimmune. Data are provided on the possible relationship between autoimmune, iodine deficiency and tumor diseases of the TG from the point of view of common mechanisms of pathogenesis and mutual influences. Emphasis is placed on the clinical manifestations of thyrotoxicosis and hypothyroidism, their effects on the cardiovascular system, and their connection with the course of rheumatic and other diseases. The importance of personalizing the diagnosis of TG pathology and the mandatory exclusion of possible associated diseases is shown.

Aim. To study the immediate efficacy, tolerability and predictors of response to prolonged-acting somatostatin analogues (SSAs) in patients with ectopic ACTH syndrome (EAS).
Materials and methods. A multicenter, observational study with a retrospective analysis. The effectiveness of treatment was evaluated every 12–24 weeks by the activity of hypercortisolism, clinical symptoms of the disease, control of tumor growth. Patients were conditionally divided into “responders” and “non-responders” at time points of 6, 12 and 24 months. Radiological efficacy was performed according to the RECIST 1.1. Statistical data processing was carried out by using IBM SPSS Statistics 23.
Results. The study included 46 patients (26 women, 20 men). The median follow-up period was 71 months [32; 122]. Localized tumor process (T1-3N0M0) – in 19 (41.3%) patients, locally widespread (T1-3N1M0, T4N0-1M0) – in 15 (32.6%), generalized (T1-4N0-1M1) – in 12 (26.1%) cases. Surgical treatment was performed in 33 (71.7%) patients. SSAs were the first-line therapy for all 46 patients. The average duration of SSAs use was 34 months (Me 27.5 [13.8; 41]). Dose escalation was required in 39.4% cases, the period before the first dose escalation was on average 9 months. 13 (48.1%) patients achieved drug-induced remission of the disease. Normalization of cortisol in 24hUFC or its decrease ≥50% from the baseline level by the 6th month of treatment was achieved in 46.4%, by the 12th month – in 61.9%, “eluding” from the effect of therapy was observed in 3 patients. Objective response was evaluated in 30 patients. There was no complete response to the treatment. In 4 (13.3%) cases – a partial response, in 15 (50%) – disease stabilization, in 11 (36.7%) – disease progression. The best therapeutic efficacy of SSAs is associated with bronchial NET (HR 0.078, 95% CI 0.010–0.633; p=0.017), and resistance to treatment is associated with negative expression of SSTR5 (HR 6.532, 95% CI 1.019–41.878; p=0.048).
Conclusion. SSAs are the drugs of choice for the first-line treatment of patients with EAS, allowing for long-term effective control of hypercortisolism and tumor progression in more than 60% of patients. Significant factors determining the response to SSAs after 6 months of treatment are expression status of SSTR5 and NET localization.

Aim. To create a mathematical model, which will predict the development of type 2 diabetes mellitus (DM 2) in individuals with visceral obesity and/or prediabetes.
Materials and methods. Clinical and laboratory data of 330 patients were analyzed. Multivariate regression and cosinor analysis determined the most sensitive parameters influencing the development of DM 2. With the help of discriminant linear analysis, a mathematical model for predicting DM 2 was built, with confirmation of its quality by ROC analysis.
Results. In the studied groups (DM 2), prediabetes and without carbohydrate metabolism disorders (n=110), statistically significant correlations were obtained: between basal body temperature (BBT) and daily energy value – DEV (r=0.5; p0.0001), circadian rhythm amplitude glycemia and waist circumference (r=-0.7; p=0.004), age and BBT (r=0.5; p0.001). In groups without carbohydrate metabolism disorders and prediabetes, multiple regression analysis identified significant factors influencing the development of DM 2: daily amplitude of BBT, daily amplitude of glycemia and bedtime (p=0.001), DEV and meal time (p=0.0001). Cosinor analysis of the daily model of glycemia and BBT established an amplitude-phase shift (p=0.028; p=0.012). Linear discriminant analysis yielded a predictive model: D=-16.845 + age х 0.044 + gender х 0.026 + amplitude of circadian rhythm of BBT х 1.424 + amplitude of circadian rhythm of glycemia х 11.155 + bedtime х 0.054 + DEV х 0.0001 + waist circumference х 0.022 + glycated hemoglobin х 1.19, where -16.845 – constant, 0.044, 0.026, 1.424, 11.155, 0.054, 0.0001, 0.022, 1.19 – coefficients of the linear discriminant function. At D0 no development of DM 2 is predicted, at D0 the development of DM 2 is in the near future. Sensitivity ratio – 92.5%, specificity – 79.1% (ROC analysis).
Conclusion. The presented predictive model has a high (92.5%) sensitivity due to the combination of 2 mathematical analyses. Most of the applied parameters are modifiable, which makes it possible to apply this model at the preventive stage.

Aim. To determine the incidence of interstitial myocardial fibrosis (MF) in acromegaly, which leads to the development of cardiac arrhythmias and conduction disorders.
Materials and methods. A single-center study was conducted, including 70 patients with acromegaly. All patients underwent standard medical examinations, including hormonal blood tests, electrocardiograms, echocardiography, Holter monitoring electrocardiograms and magnetic resonance imaging (MRI) of the heart with gadolinium contrast, additionally 48 patients underwent T1-mapping, which is an MRI method that allows the detection of diffuse changes by measuring the values of myocardial relaxation time – T1.
Results. The study revealed a high incidence of MF – 53 (75.7%) cases (21 women, 32 men). The duration of the disease was found to be critical for myocardial remodeling (p=0.006). Compliance criteria for the T1-mapping technique were determined, with reduced T1-mapping values observed in 85.2% of cases. The ROC analysis (Receiver Operator Characteristic) determined the diagnostic value of post-contrast T1-mapping: AUC (Area Under the Curve)=0.906 (95% confidence interval 0.789–1.000), a sensitivity of 90%, and a specificity of 76.5%, indicating high diagnostic efficiency. According to the Youden index, a cut-off point of 372.5 ms was selected.
Conclusion. Myocardial T1-mapping is a novel MRI method that allows to assess the degree of MF without the need for myocardial biopsy. The obtained information is crucial for the diagnosis and prognostic assessment of heart diseases, particularly in cases of hypertrophic cardiomyopathy or infiltrative diseases. The T1-mapping method, which is actively developing, can serve as a marker for early diffuse myocardial fibrosis and help determine the prognosis for patients with acromegalic cardiomyopathy.
