Authors: Zaykova K. , Nikolova S. P. , Pancheva R. , Serbezova A.
Published: November 2024

Assessing the particular trends and factors influencing antibiotic prescription practices for pediatric patients by inpatient and outpatient physicians in Bulgaria is essential for pinpointing areas needing improvement and devising strategies to encourage judicious use of antibiotics. The aim of this study is to offer practical insights for both hospital and outpatient care. By recognizing and comprehending the specific details of antibiotic usage in pediatric healthcare, this study seeks to facilitate the creation of tailored stew-ardship strategies to address the growing challenge of antimicrobial resistance. A cross-sectional, multicenter survey was conducted between September and November 2022, involving specialists from various medical fields. The study used a 4-point Likert scale to evaluate the most prevalent clinical scenarios in which antibiotics were prescribed. A total of 222 physicians participated in the survey, with 108 respondents chosen for analysis. Their primary patient population consisted of at least 25% children. The study’s results highlight notable variations in antibiotic prescription patterns between general practitioners and outpatient physicians in Bulgaria. Specifically, general practitioners were found to have a higher tendency to prescribe antibiotics before holidays or weekends compared to outpatient physicians. Moreover, GPs in Bulgaria displayed an increased likelihood of prescribing antibiotics when they had personal familiarity with the patient and did not consider further tests necessary. They also exhibited lower rates of prescribing antibiotics based on antibiogram and blood test results compared to outpatient physicians. Healthcare providers play a crucial role in addressing antimicrobial resistance, highlighting the necessity of their proactive participation in combating this global health concern. Despite being aware of the issue, there is need for additional education and interventions to enhance appropriate prescribing practices. The authors underline the significance of adopting a well-balanced approach to antibiotic prescription, taking into account both individual patient requirements and potential public health implications associated with antibiotic misuse.
Antimicrobial Susceptibility of Fructophilic Lactic Acid Bacteria on PHZM Gene of Pseudomonas Aeruginosa Isolates from Wounds Infected
Authors: Anwer A. W. , Ahmed M. E.
Published: November 2024

Introduction

The study was to isolate and characterize fructophilic lactic acid bacteria (FLAB) species from the honey bee gut. Based on the results of this study, it was found that the FLAB species obtained from honey were gram-positive and catalase-negative, and this identification was confirmed through 16S rRNA gene sequencing.

Materials and methods

The results indicated that yeast extract was the most effective nitrogen source, while glucose was the preferred carbon source for cell-free supernatant (CFS) production. The optimal pH for CFS production was found to be 5, and the incubation period of 72 hours was determined to be the most suitable for obtaining a high yield of CFS. Another aspect of the study aimed to identify multidrug-resistant P. aeruginosa isolates from burn wound infections. The isolates were identified using the VITEK 2 system, and the phzM gene was detected in all nine strains. Furthermore, the study evaluated the effect of the CFS of the selected strain (E5) on the expression of the phzM gene.

Results

The study showed a significant down-regulation of phzM gene expression in multidrug-resistant P. aeruginosa isolates following exposure to the CFS, indicating the potential of E. faecium as an effective antimicrobial agent against P. aeruginosa infections that are resistant to multiple drugs. We performed a primary screening to evaluate the effect of the CFS obtained from E. faecium (E5), and it was observed that the CFS showed a high inhibition zone of 23 mm against multidrug-resistant P. aeruginosa, as determined by the agar well diffusion assay. The study also investigated further to determine the optimal conditions for producing CFS.

Conclusion

Down-regulation and up-regulation in the expression of the genes following exposure to CFS indicate the potential of E. faecium as an effective antimicrobial agent against multi-drug resistant (MDR) P. aeruginosa infections.
Left Amyand’s Hernia in A 1-Year-Old Male Infant: Report of a Rare Case in Common Presentation
Authors: Fikri E. , Alnaz A.
Published: November 2024

Amyand’s hernia is a rare type of hernia with the appendix and cecum trapped in a hernial sac. A one-year-old male infant was referred with irreducible left inguinal hernia for about 1 week. No signs of intestinal obstruction were presented, and pain was tolerated. A herniotomy was performed on the patient. Intraoperatively, the appendix and cecum were found in the left hernial sac, which this rare presentation named left Amyand’s hernia. Cecum and appendix were considered normal. No perforation and significant inflammation were found; hence, no appendectomy was performed. Left Amyand’s hernia is a very rare case, mostly in pediatric surgery, in which the current decision of diagnosis-making can only be made intraoperatively.

Published: November 2024

The liver performs many vital functions such as regulating homeostasis, bile production, storage of vitamins, and more. Another important function of the liver is to neutralize toxic substances entering the body. Substances entering the human body can be eliminated unchanged, retained unchanged, or undergo chemical transformation. Drugs are one of the most important and common causes of hepatotoxicity. It can manifest in various forms, ranging from elevated serum levels of transaminases to acute liver failure. The mechanisms of drug-induced liver damage may include the formation of a toxic metabolite (paracetamol), induction of oxidative stress, mitochondrial damage, suppression of key transcription factors and enzymes (methotrexate), suppression of beta-oxidation (valproate), impaired bile secretion and others. In some cases, hepatotoxicity is an idiosyncratic type and the exact mechanism of damage is unclear. Due to the importance of the problem, knowledge about the metabolism, potential adverse drug reactions, and the correct dosage regimen is essential.

Published: November 2024

The capacity of the F3K Digitalis purpurea cell line to biotransform hydroquinone into β-arbutin was tested. The experimental protocol involved the sequential addition of hydroquinone to the culture medium, and testing different precursor (4-, 5-, and 6 mM) and sucrose concentrations (3 % and 6 %) under different lighting conditions (16-hour photoperiod and darkness). The biotransformation process was positively influenced by the photoperiod regime and increased sucrose concentration. The highest arbutin production (1 g/L) has been achieved in cell suspensions fed with 6% sucrose and 5 mM hydroquinone, under 16 hours daily light exposure.
Preliminary studies on the allelopathic potential of two invasive species of Solidago against selected cereal weeds
Authors: Mołdoch Jarosław , Domaradzki Krzysztof
Published: November 2024

The European Union is currently pursuing a policy of moving away from synthetic plant protection products to natural ones. This is reflected in the search for natural substances that can replace them in agricultural production. Many studies indicate that invasive species of Solidago have such allelopathic potential. The aim of the study was to assess the effect of extracts of two Solidago species (Solidago gigantea L. and Solidago canadensis L.) on the growth and development of cereal weeds: Chenopodium album, Papaver rhoeas and Agrostemma githago. Using liquid chromatography coupled with mass spectrometry (LC - MS) techniques, the material (crude extract, phenolic and saponins fraction) was standardized and tested for allelopathic activity using the modified first generation biotest. The results indicate the phenolic fraction (20.04 mg/g dry weight of Solidago gigantea; 21.03 mg/g for Solidago canadensis) and saponin fraction (2.27 and 3.74 mg/g dry weight respectively). Both fractions from S. gigantea are characterized by high phytotoxicity in relation to Ch. album, causing over 90% reduction of its biomass in relation to the control. For P. rhoeas these differences are not so clear. Biomass reduction by the phenolic fraction was 20% and by the saponin fraction 50%. In the case of S. canadensis, allelopathic activity was not as pronounced and ranged from 20–40% for the saponin fraction relative to the P. rhoeas. The highest resistance to preparations made from both species of Solidago was demonstrated by A. githago.
Volatility Implications for Asset Returns Correlation
Authors: Ivanov Illia
Published: November 2024

Although there is an extensive literature on the impact of volatility on asset returns correlation, investigating this in relation to broad asset selection and in perspective of different timelines has received less attention. In comparison to the previous papers, we use a much broader set of 35 selected asset classes and used rolling returns for five different periods ranging from 3 months to 5 years to calculate rolling correlations, which was used further for regression analysis between rolling correlation and volatility index (VIX). Results showed more impact of volatility on the mid-term horizon, such as 1 year, possibly meaning that for longer periods, structural economic factors impact correlation significantly, while for shorter periods, immediate market reactions to events and short-term fluctuations reduce the impact of the correlation. Autocorrelation of residuals suggests that correlation follows trends, which is evidenced more in longer periods. The study contributes to existing literature by comparing the volatility impact across a broad range of assets and multiple time horizons, revealing that correlation is sensitive to time horizons – overall and in terms of responses to heightened volatility. Also, the impact of volatility is different over different time periods, with most impact for the mid-time horizon, such as 1 year.
Wine from Međimurje – from Rome to Decanter
Authors: Kalšan Janko
Published: November 2024

The paper ‘Međimurje Wine - From Rome to the Decanter’ provides a systematic overview of the exceptional tradition of wine production in Međimurje. As one of the most important economic branches for the people of Međimurje, as well as for numerous lords and rulers of the region between the Mura and Drava rivers, its roots date back to the Roman Empire. In the modern era, in the second half of the 20th and early 21st centuries, it was fully realised and presented to the world. The aim of this work, based on numerous sources, is to show the development and numerous changes in vine cultivation and wine production throughout its long history but also to tell the story of the connection of a large part of the Međimurje population with this economic branch. The fertile soil and climate, combined with new varieties and techniques, as well as the association of winemakers, have certainly contributed to the creation of Međimurje wines. This has resulted in an exceptional leap in quality and promotion, creating a consistency in the wines that has led to outstanding results recognised at both national and global levels.
The Impact of Green Knowledge Management on Sustainable Development Goals and Green Innovation in French Economic Firms: A Structural Analysis
Authors: Alioune Abdelhak
Published: November 2024

The study aimed to test the impact of Green Knowledge Management (GKM) on Sustainable Development Goals (SDGs) and Green Innovation (GI) in economic firms. The researcher collected data from lower, middle, and upper-level managers of small, medium, and large-sized manufacturing and services firms located in France. The data were analysed using structural equation modelling (SEM) to explore how GKM processes (creation of green knowledge, acquisition, sharing, and application) impact SDGs (environmental, social, and economic sustainability) and GI (green technology, management innovation). According to the results, GKM significantly impacts both SDGs and GI. The dimensional analysis indicated that, except for acquiring green knowledge and its application, it showed an insignificant impact on green innovation. Finally, firm size and industry type were examined in relation to SDGs and GI. Regarding SDGs, firm size presented significant positive results. However, an insignificant result was found for firm size concerning GI. Similarly, the role of industry type was examined in relation to SDGs and GI, revealing significant results for both paths.
Proceedings of the Second Symposium of the Dionysius Circle: Platonic Participation without Platonic Forms: Thomas Aquinas on the Key Insight of Dionysius’s De divinis nominibus
Authors: Zoll Patrick
Published: November 2024

According to Aquinas, the Platonic doctrine of participation can be disentangled from a commitment to the theory of Forms which Aristotle attributes to Plato. In this article, I argue that we can learn three important things from close examination of this key insight. First, we can better understand Aquinas’s view of how the participation of an effect in its cause works. Second, the Platonic doctrine of participation can play an important role in explaining and defending Christian doctrines such as the doctrine of creation and the doctrine of divine simplicity. Third, it is possible to combine the Platonic doctrine of participation with Aristotle’s alternative account of forms into a coherent and powerful metaphysical synthesis.

Published: November 2024

Drought, as abiotic stress, has significant detrimental effects on the growth, physiology, yield and nutritional quality of plants. The distinctive characteristics of nanoparticles (NPs) significantly contribute to essential physiological processes, indicating their considerable potential in promoting plant growth. This study investigated the effects of different NPs, including aluminium oxide nanoparticles (ANPs), silica nanoparticles (SNPs) and titanium dioxide nanoparticles (TNPs), on the growth and photosynthesis of okra (Abelmoschus esculentus L.) seedlings under drought stress conditions. The growth characteristics of okra plants were assessed after 48 days of watering. Photosynthetic parameters like photosynthetic rate, transpiration rate, intercellular CO2 concentration (Ci), stomatal conductance and water use efficiency (WUE) were measured with a portable photosynthesis system. The results demonstrated that both ANPs and SNPs can promote the growth and photosynthesis activity of okra plants, with SNPs exhibiting a stronger effect compared to ANPs. The administration of 50 mg · kg−1 SNPs for a defined period demonstrated the most pronounced enhancement in growth and photosynthetic properties. In contrast, TNPs were found to have a significantly harmful influence on the growth and photosynthetic properties of the okra plant. These findings lay an important foundation for assessing the effects of nano oxide particles on okra plants.
Challenges and Strategies in Elephant Conservation: A Comprehensive Review of Land Use Impact and Management Approaches in Dalma Wildlife Sanctuary, India
Authors: Kumari Indu , Pradhan Lolita , Chatterjee Sudipto
Published: November 2024

The Dalma Wildlife Sanctuary, a critical habitat for elephant conservation in the Dalma Landscape, is increasingly experiencing the multifaceted impacts of climate change. This study reviews secondary literature to examine the consequences of Land Use and Land Cover (LULC) changes on elephant populations, emphasizing the exacerbating effects of climate-induced alterations. The sanctuary faces challenges like habitat degradation and fragmentation, which impede wildlife movement and intensify human-wildlife conflicts, particularly with elephants. These issues are now compounded by climate change, which is altering vegetation patterns, water availability, and seasonal behaviours of wildlife, further straining the delicate balance of this ecosystem. This paper methodically dissects the literature, highlighting how climate change interplays with existing environmental stressors, affecting the conservation strategies and viability of elephant corridors. The review also considers management strategies, underscoring the need for adaptive measures that address the dual challenges of habitat degradation and climate change. By broadening the scope to include the climate change dimension, this research not only underscores the researcher’s comprehensive understanding of the sanctuary’s ecological challenges but also aligns the study with global environmental concerns, making it relevant in the context of contemporary wildlife conservation efforts. Through a structured approach, the paper is divided into sections that explore the sanctuary’s ecological significance, the factors impacting elephant populations with a focus on climate change, and methods for studying human-elephant conflicts in the context of a changing climate. This comprehensive analysis aims to identify research gaps, propose adaptive conservation strategies, and contribute to the broader understanding of how climate change is reshaping wildlife conservation paradigms.
Economic development instruments employed following the closure of an industrial plant – the example of Polish municipalities
Authors: Cybulska Magdalena
Published: November 2024

This article addresses the issue of the impact of industrial plant closures on the economic policies currently being pursued in Polish municipalities. The survey indicated differences between municipalities that have experienced industrial plant closures and those that have not. The nonparametric Mann–Whitney U test indicated statistically significant differences in the overall approach of municipalities to the economic policies currently being implemented (attracting large and foreign investors), and in their use of several economic development instruments – namely, investment fairs, business incubators, investor services at the office and job activation programmes. The results show the importance of instruments for shaping the local labour market and indicate areas of support that are also relevant from above the local level in terms of territorial policy objectives.
Study of the Influence of Temperature and Pressure on the Intensity of Gas Hydrate Formation
Authors: Pavlenko Anatoliy
Published: November 2024

The paper analyses the influence of pressure and temperature of gas and liquid on the process of hydrate formation, proposes equations that allow to predict the course of heat and mass exchange processes of gas hydrate synthesis and estimate the amount of gas hydrate obtained at given thermodynamic parameters. The synthesis of gas hydrates begins with the creation of appropriate thermodynamic conditions in the reactor. However, the formation of hydrate layers on the surfaces of gas bubbles in bubbling or high-speed mixing technologies has peculiarities associated with the fact that the temperature and pressure of the gas change depending on the bubble size fluctuations. This should be taken into account when determining the conditions of hydrate formation. To this end, the article proposes a mathematical model that allows the thermodynamic conditions of synthesis to be optimised. The obtained results can be used to design process equipment and optimise its parameters.

Published: November 2024

Agriculture is one of the main sources of greenhouse gas (GHG) emissions and has great potential for mitigating climate change. For example, agriculture in Latvia was the second largest sector of GHG emissions after energy with a 22.2 % share of total GHG emissions in 2022. The study aims to compare and analyse the amount of GHG emissions generated by agriculture per domestic product (GDP) and population in different European countries. The ambitious goals set in Europe for 2030 envisage a 30 % reduction in the industry, however, in some countries, these indicators have not only decreased in recent years but also increased. The structure of GHG emissions in 2022 in Europe is as follows: intestinal fermentation (181.1 MtCO2e), agricultural soils (112.9 MtCO2e), and manure management (61.7 MtCO2e). Agriculture is one of the main sources of GHG emissions and has great potential for mitigating climate change. This study aims to compare and analyze GHG emissions from agriculture in European countries against GDP, GDP against population, and population in 2022.

THE OBJECTIVE was to evaluate the immediate results of open reconstructive operations for renal artery aneurysm.

METHODS AND MATERIALS . From March 2019 to September 2023, 55 patients with visceral artery aneurysms were operated at the Department of Vascular Surgery at the Pavlov University. 4 patients with renal artery aneurysms were operated on by open surgical method and 5 patients underwent endovascular operation. There are two clinical cases of open reconstruction of renal artery aneurysm in situ and one ex vivo. In all cases, the indication for the operation was the presence of a symptomatic aneurysm. For in situ reconstructions, a retroperitoneal thoracophrenopararectal access to the tenth intercostal space on the left side with the opening of the left pleural cavity and partial diaphragmatic cavity and a transverse laparotomy of «chevron» type were used. Autovena was used as a bypass. For surgery of the renal artery ex vivo laparoscopic nephrectomy with autotransplantation of the kidney was performed. In the near postoperative period, we made the assessment of the patency of the reconstruction zone using MSCT angiography, the analysis of indicators of renal function.

RESULTS . All the observations noted satisfactory near-term results – the reconstruction zone is unobstructed, indicators of renal function without negative dynamics, absence of clinical manifestations of this pathology. Long-term results   (observed for more than 4 years) were traced in one patient. During this period, normal renal function and adequate functioning of the reconstruction zone are maintained.

CONCLUSION . Open reconstructive surgery in the surgical treatment of renal artery aneurysm remains relevant due to the inability in some cases to perform its endovascular correction without high risk of ischemic damage to the parenchyma of the kidney.

Published: November 2024

INTRODUCTION. The Zenker’s diverticulum is a protrusion of the wall of the pharyngeal-esophageal junction from the area of the Killian triangle as a result of persistent spasm of the cricopharyngeal muscle. The prevalence of the disease in Russia is 3 cases per 100 thousand people, in the world 0.01–0.11 %.

METHODS AND MATERIALS . At the N. N. Burdenko Faculty Surgery Clinic of the I. M. Sechenov First Moscow State Medical University 2 patients with small diverticulum underwent endoscopic tunnel cricopharyngeal myotomy and 3 patients with large diverticulum underwent video-assisted transaxillary diverticulectomy.

RESULTS . Compared with surgical methods for the treatment of Zenker’s diverticulum endoscopic methods have a lower complication rate, but a higher recurrence rate.

CONCLUSION. Despite the introduction of new treatment methods, it is advisable to adhere to a differentiated approach to the treatment of Zenker’s diverticulum. Surgical treatment is indicated for patients with a large diverticulum in the absence of contraindications to surgery. Transluminal endoscopic methods, including cricopharyngeal tunnel myotomy, can be considered as a treatment for patients with small-sized Zenker’s diverticulum, as well as patients with large diverticulum who have concomitant diseases and contraindications to traditional surgery.

Published: November 2024

Bile duct injuries occur in 0.4 % of elective and 0.8 % of emergency laparoscopic cholecystectomies. The risk factors for bile duct damage and the optimal timing of laparoscopic cholecystectomy were studied. The emphasis is on theoretical and practical training of the surgeon as the main component of the prevention of bile duct injuries. The variant anatomy of vessels, bile ducts and important anatomical landmarks during the operation are described. During «complex cholecystectomy», «rescue strategies» are proposed and modern imaging techniques are reviewed. The concept of safe cholecystectomy is evaluated. The issues of damage classification are touched upon. Analysis of the literature showed that debate continues in the global surgical community about the correct tactics for managing these patients. There is also a problem in assessing complications and there is a lack of standardization of outcomes after laparoscopic cholecystectomy.

Internationalization of teaching and research in Higher Education
Authors: Mushfiq Merab
Published: November 2024

Internationalization as a result of globalization is a focus in higher education institutions to develop and implement strategies at institutional level to stay competitive in the global market. While internationalization is usually measured with student mobility whether it is in terms of international and exchange, there has been a shift and a push to internationalize in other areas of higher education such as staff and faculty recruitment and retention, cross-culture collaborations and partnerships in research, teaching and learning, and curriculum. Internationalization of teaching and research is now even more needed because the number of international students, exchange, and scholars have been increasing around the world, bringing equity between Global North and South, and to equip current students and future generations to intercultural understanding and awareness through education medium. There are recommendations given towards the end of this paper to implement strategies to internationalize teaching and research practices for faculty, scholars, and practitioners within higher education.
A Dangerous Conflation
Authors: Barron Katherine
Published: November 2024

Modifying the curriculum is a common practice used to support students with Individual Education Plans (IEPs). Up to 15% of students in the Toronto District School Board (TDSB) have curriculum modifications by the time they reach Grade 8. Yet, despite their frequent use, the efficacy of this long-standing practice has rarely been studied. Research from Author (2022) suggests that racialized students are disproportionately overrepresented in this practice. Furthermore, their research suggests that there are negative long-term impacts associated with this practice. This literature review queries what is known about curriculum modifications. Findings reveal two significant issues with the terminology used in the existing literature. Additionally, the limited research available centres on only one exceptionality group (students with significant intellectual disabilities). These findings lay a foundation for future research on curriculum modifications—an area that warrants urgent attention from the anti-oppression movement within special education.

Published: November 2024

There is a great need to improve plant resilience to unpredictable environmental stresses; therefore, understanding the leading role of Titanium dioxide (TiO2) nanoparticles in alleviating plant stress is crucial for the development of abiotic stress-tolerant endangered plant species. Recently, many new methods have emerged to synthesize nanoparticles, among which the biosynthesis method deserves more attention due to its features such as being eco-friendly, and cost-efficient. The aim of the present study is to perform green synthesis of nanoparticles from extracts and investigate the effect of these nanoparticles on plants. The complete shape and size of the synthesized nanoparticles were analyzed by UV-visible spectroscopy (UV-Vis), Particle Size Analysis (PSA), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) modern instruments. The absorption peak at 310 nm wavelength obtained from UV–Visible spectroscopy analysis confirmed the synthesis of TiO2 nanoparticles (NPs). The presence of strong and broad peaks in FTIR indicated the presence of phytochemicals functional groups and the presence of NPs. SEM result showed that most of the synthesized nanoparticles had spherical angular structure and their size was 75 nm. The effects of TiO2 NPs on Swietenia macrophylla L. an endangered plant species listed in IUCN (International Union for Conservation of Nature) showed that seed germination and plant survival rates were higher than control plants and there was also significant variation in root and shoot development and growth of leaves. The growth rate of the plants was significant compared to control and the chlorophyll pigments content was also recorded significant in the treated plants. The 21 phytochemicals were identified in the plant leaves analyzed with GC-MS. The ISSR analysis result showed polymorphic DNA a band which was as mutants in phenotypic characters of plants. Flow cytometric results had shown that DNA replicate content was increased due to TiO2 NPs effect in plants treated with 200 mgL-1 showed the higher plant growth efficiency.

OBJECTIVES: To explore the extent of functional improvement following primary total knee arthroplasty for knee osteoarthritis and to compare the trajectories of self-reported and performance-based measures of physical function.

DESIGN: Longitudinal systematic review with meta-analysis

METHODS: We searched 3 electronic databases from January 2005 to February 2023 for longitudinal cohort studies involving adults with knee osteoarthritis undergoing primary total knee arthroplasty. Estimates of self-reported and performance-based physical function were extracted presurgery and up to 5 years postsurgery. Risk of bias was assessed using a 6-item checklist. Self-reported function scores were converted to a 0-100 scale (higher scores indicate worse function). Mixed models provided pooled estimates after excluding low-quality studies.

RESULTS: Out of 230 relevant studies, 72 (n = 19 063) of high quality were included in meta-analyses. Self-reported function significantly improved from presurgery (55.6/100; 95% confidence interval [CI], 53.1 to 58.1) to 3-6 months postsurgery (21.1; 95% CI, 17.9 to 24.3; P<.001). A small decline in self-reported function occurred at 6-12 months (31.0; 95% CI, 25.8 to 36.2; P<.001), with no further change at 12-24 months (30.9; 95% CI, 23.2 to 38.6; P = .919). Performance-based measures exhibited variable trajectories, with most estimates indicating no clinically meaningful improvement following total knee arthroplasty.

CONCLUSION: Total knee arthroplasty resulted in clinically meaningful improvements in self-reported function at 3-6 months postoperatively. There was some deterioration in function after 6 months, and at no other time point did the estimate reach a clinically important change. There was limited evidence of clinically meaningful improvements in performance-based measures of physical function at any time point. J Orthop Sports Phys Ther 2025;55(1):1-11.

The Weber Controversy: the Problem of Periodization of the Emergence of Capitalism
Authors: Trubitsyn O. K.
Published: November 2024

Many contemporary researchers suggest rejecting Weber’s approach, linking the formation of modern capitalism to Protestantism, as completely false. In particular, they point out the complexity of periodization: in their opinion, capitalism did not arise in the Reformation era, but much earlier. The article substantiates the thesis that the attempt to refute the Weber thesis by pointing out the incorrectness of its periodization seems unconvincing. Rational capitalism really emerged after the Reformation and exactly where it achieved success, which gives certain grounds for the hypothesis of the connection between the Reformation and the formation of rational capitalism. Of course, this in itself does not prove the truth of the Weber hypothesis, but in any case we cannot consider it to be obviously incorrect.

Lighting plays a key role in the perception of works of art. This is a really important issue, which for a long time was not interested in, because there were strict regulations on how to light, formulated back in the USSR, but time flies forward and recommendations and requirements should keep up and keep up with modern trends and technological capabilities. For effective perception of works of art it is important to choose the right lighting. It should accentuate the shape, texture and color of the object, as well as create natural shadows and atmosphere to help the viewer better understand and appreciate the artwork. However, traditional lighting methods can result in unnatural shadows and glare, which negatively affects the perception of the artwork. Current technologies allow for virtual displays that are accessible to a wide audience, but they require realistic visualization of synthetic images of the sculptures. Modulation of lighting in global calculation programs and the use of color perception models will make it possible to analyze and test different approaches to lighting, taking into account a variety of parameters, and, having conducted a number of experiments, to identify with sufficient accuracy the positive and negative sides of solutions and recommend the necessary ones in different situations and circumstances.

Recently, situations have increasingly arisen when the customer needs to conduct optical modeling or rendering of scenes that represent a trade secret. Therefore, the customer is not ready to share scene data with the owners of software for realistic rendering systems, and he is also not ready to purchase expensive software. Thus, a problem arises when the customer of the rendering service is afraid of data leaks, and the software developer is worried about the pirated use of an expensive realistic rendering system. As a result, a task arises when it is required to render scenes without transferring the software to the customer and without providing the scene to the software owners. In this paper, we consider the solution to this dilemma through the use of federated rendering methods, when all the data remains completely on the side of the rendering customer, and the entire rendering process is managed by the owners of the realistic rendering system. As part of the study, federated rendering using forward and reverse ray tracing methods was implemented, and the results of rendering and their comparison with the results of using a traditional realistic rendering system were presented.
A SIMPLIFIED METHOD FOR CALCULATING METALLIC PAINT COLOR
Authors: ERSHOV S.V. , VOLOBOY A.G.
Published: November 2024

Modern automotive paints have a complex structure and consist of many pigments of different nature. Modeling metallic paints which contain both coloring pigments and reflective particles, is a complex task. In these paints, aluminum particles are mainly responsible for the texture, and coloring diffuse pigments are responsible for the color. This allows us to divide the paint matching task into two stages: separately find the type of aluminum particles, and then model the color change using coloring pigments. In this paper, we focus on the second stage and propose a simplified method for calculating the color of metallic paint. Comparisons with the baseline exact method which uses stochastic ray tracing in the paint structure, and with measured data demonstrated acceptable accuracy of the proposed method. At the same time, our method is significantly faster. This allows us to use it in the optimization problem of color matching, where the color calculation is performed multiple times.

Published: November 2024

The use of differentiable rendering methods is a relevant solution to the problem of reconstructing real-world geometry. The main issues with such methods are the geometric distortions that occur during optimization and the high computational complexity. The article considers the possibility of using three-dimensional visual hulls as a primary representation for optimizing geometry using differentiable rendering methods. An algorithm for forming the primary geometry of an object for further optimization of this geometry by differentiable rendering methods is proposed. The introduction of an additional stage of geometry formation allows not only to increase the accuracy of geometry reconstruction but also to create a homeomorphic form for the possibility of correct reconstruction of the object's geometry through continuous transformations of the model parameters, which increases the versatility of the mentioned methods.

Displaying points of a multidimensional information text array on an elastic map to assess the relative position of semantic proximity areas
Authors: BONDAREV A.E.
Published: November 2024

The article presents the results of computational experiments on displaying the points of the original multidimensional information array on the elastic map scan to assess the relative positions of semantic proximity areas in order to improve the processing of text information. Elastic maps are considered as a tool for providing analytical work with text information. As previous works show, in order to obtain the required distances corresponding to the cluster picture of the studied multidimensional volume, it is necessary to use the distances on the elastic map, which reflects the cluster portrait of the studied multidimensional data volume. The paper presents the cluster structures of points of the studied multidimensional volume obtained in this way on the elastic map scan in the plane of the first two principal components. An analysis of the relative positions of clusters of different configurations at different points in time is presented.
