O limiar da mobilidade urbana: aspectos geo-históricos dos bondes e do transporte ferroviário de passageiros em Juiz de Fora/MG
Authors: Reis Rafael Ribeiro , Machado Pedro José de Oliveira
Published: October 2024

Este artigo apresenta alguns resultados da nossa pesquisa de mestrado em Geografia, sobre mobilidade urbana em Juiz de Fora/MG. Objetiva-se apresentar a origem e evolução dos meios de transporte coletivo urbano locais, entre 1875 e 1997. O estudo fundamentou-se nos marcos regulatórios históricos do sistema de transporte municipal e em bibliografia específica sobre o tema. Os resultados estabeleceram um panorama da evolução da mobilidade urbana no transporte coletivo, desde os bondes movidos à tração animal, sua transição para os modelos elétricos, até o período de operacionalização do trem suburbano denominado “Xangai”. Conclui-se que Juiz de Fora, pioneira no Estado em introduzir o transporte urbano ferroviário de passageiros, desde o final do século XIX, rendeu-se ao rodoviarismo dos ônibus urbanos, a partir de 1970, mesmo tendo logrado, por quase um século de sua história, um grande sucesso a partir de seus trilhos.

Unravelling Exponential Growth Dynamics: A Comprehensive Review
Authors:   School of Mathematics and Computing, Kampala International University, Uganda, Arinze Echegu Darlington
Published: October 2024

Exponential growth refers to the rapid change of natural and man-made systems, characterised by unbounded growth, sensitivity to starting conditions, and self-perpetuating character. Technological developments, network effects, population changes, market dynamics, and environmental factors all contribute to exponential growth, which has economic, social, and environmental consequences in a variety of areas and businesses. Public health concerns, moral dilemmas, and economic, environmental, and social consequences arise from exponential growth, despite promoting innovation and progress. Emerging trends in exponential growth dynamics include artificial intelligence, biotechnology, healthcare, sustainable technologies, demographic changes, urbanisation trends, and digital transformation. These patterns provide insight into how exponential development can affect ecosystems, economies, and society in the future. This paper aims to provide a comprehensive understanding of the dynamics of exponential development, highlighting its broad implications and pervasive impact in a rapidly increasing world. We must implement the latest technological developments and ensure environmental sustainability to fully harness its potential. Encouraging multidisciplinary cooperation, ecologically friendly methods, and ethical issues can accelerate innovation, economic expansion, and social well-being. This growth’s collective benefit is critical for current and future generations. We utilised relevant published data (2004–2014) from diverse, reliable databases. The review suggests that to harness its exponential growth potential, we must take proactive measures, such as utilising new technology and addressing environmental sustainability. Collaborating with professionals, implementing sustainable methods, and upholding ethical standards can lead to innovation, prosperity, and societal well-being. Keywords: Dynamics, exponential, growth, comprehensive, unravelling

Understanding Autoantibody Tests in Systemic Inflammatory Diseases
Authors: Lee Soo-Young , Bae Kil Seong , Rhim Jung Woo , Jeong Dae Chul
Published: October 2024

Autoantibodies are diagnostically useful markers of systemic inflammatory diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), Sjögren’s syndrome (SjS), systemic vasculitis, and antiphospholipid syndrome (APS). Regardless of the role of autoantibodies in the pathogenesis of Kawasaki disease (KD), autoantibody testing may be performed in some KD patients due to the atypical presentation of the disease. This review describes four types of autoantibodies that KD practitioners often encounter in their practice: antibodies for RA, anti-nuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies (ANCA), and anti-phospholipid antibodies (aPL). In patients with RA, rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibody are tested. Due to differences in specificity, anti-CCP antibodies are preferred over RF in RA patients. ANA is the most frequently tested autoantibody in actual practice. If ANA is positive (≥ 1:160), additional testing for ANA subtypes is performed based on ANA staining patterns (e.g., homogenous or speckled) and suspected autoimmune diseases (e.g., SLE, SSc, or SjS). ANA subtypes include anti-dsDNA, anti-Ro/La, anti-Sm/U1-RNP, anti-Scl-70/centromere, anti-histone, anti-ribosomal P, and anti-Jo-1 antibodies. ANCA testing is performed in patients with suspected small vessel vasculitis, such as granulomatosis with polyangiitis (GPA, formerly Wegener’s granulomatosis). aPL is used to diagnose primary and secondary APS. In conclusion, various autoantibodies can be found in one disease, and one autoantibody can be found in many diseases. Some autoantibodies are also found in healthy children and adults. Clinicians, including KD practitioners, need knowledge and experience with autoantibody testing to appropriately interpret laboratory results.
Macrophage Activation Syndrome Complicating Kawasaki Disease: An Initial Presentation of Systemic Juvenile Idiopathic Arthritis
Authors: Lee Soo-Young , Rhim Jung Woo , Jeong Dae Chul , Kang Jin Han
Published: October 2024

Kawasaki disease (KD) is one of the leading causes of macrophage activation syndrome (MAS) in children, so the possibility of developing MAS should be suspected in KD patients who do not show clinical improvement despite appropriate treatment. At the same time, since MAS is a hyperinflammatory phenomenon that can occur in various medical conditions that cause severe systemic inflammation, the possibility of coexisting undiagnosed underlying diseases must also be considered in children with MAS. Here, we report the case of a 16-month-old girl with systemic juvenile idiopathic arthritis (SJIA). The patient presented with severe clinical manifestations that met the diagnostic criteria for both KD and MAS, including KD-like features, splenomegaly, cytopenia, and hyperferritinemia. She was diagnosed with MAS complicating KD (MAS-KD) and underwent 40 weeks of combination chemotherapy. No further clinical deterioration was observed during chemotherapy including etoposide and cyclosporine. However, after completing immunosuppressive therapy, the typical symptoms of SJIA finally appeared. Although KD, MAS, and SJIA are distinct diseases, they may share similar clinical phenotypes. The relationship between these three diseases will be an interesting research topic for KD and KD-like inflammatory diseases.

Published: October 2024

Within the public founded project “NanoKompakt”, the powder of initial amorphous soft magnetic alloy Vitroperm (Fe73.6Si15.5B6.9Cu1.0Nb3.0) is compacted to nanocrystalline components by FAST/SPS. The aim is to manufacture industrially relevant components such as E-cores that cannot be produced from wounded ribbon. The increased mechanical stability allows for omitting a polymer case, which increases the possible application temperature. Firstly, small toroidal cores were compacted. A high permeability of 20 000 and a low coercivity of 3 A/m are achieved. Based on the thermal and electrical properties of the compacted toroidal cores, a larger pressing tool is also designed and optimized by simulation. The simulation is necessary because the temperature range for compaction is only a few Kelvin wide and the precipitation of hard magnetic phases must be prevented. In the second step, E-cores are cut from compacted slices and analyzed.

Published: October 2024

In this study, rheology, structure and melt spinnability of thermoplastic starch TPS/PLA blend compounds as well as characteristics of melt spun fibers was studied. Thermoplastic starch is further modified with tartaric acid and blends are compatibilized using graft copolymer, maleic anhydride grafted PLA. Results from rheology analysis of compounds shows significantly reduced melt flow rate MFR and reduced viscosity as a result of tartaric acid modification and compatibilization, but the viscosity was increased as TPS_TA content in the blend increased. In addition, storage modulus (G`) and loss modulus (G``) were increased with increasing TPS_TA content in the blends. Fourier transform infrared spectroscopy FTIR analysis confirmed O-H peak shifts and peak intensity changes associated to starch thermosplasticization and further peak shifts associated with more O-H bond breakages due to tartaric acid modification, indicating acid hydrolysis action of tartaric acid which agrees with results from rheology study. Melt spinning trials show the possibility of melt spinning of biopolymer fibers from blends with up to 40%w/w TPS_TA content. The melt spun fibers have diameter in range of 12.0–124.0 μm depending on take up speed and TPS_TA content. Differential scanning calorimetry DSC analysis of melt spun fibers shows glass transition Tg shifts attributed to molecular orientation and rigid amorphous TPS phase formation as well as the occurrence of double melting peaks Tm associated to different crystals resulting from induced crystallization. The overall result from this study shows the possibility of melt spinning thermoplastic starch/PLA blend biopolymers in to fibers, revealing opportunity to utilize starch biopolymer for fiber spinning. Furthermore, the results also show the need for further research engagements to get fibers with better performance.
Dynamic Resource Allocation and Energy Optimization in Cloud Data Centers Using Deep Reinforcement Learning
Authors: Li Haoran , Wang Gaike , Li Lin , Wang Jiayi
Published: October 2024

This paper presents a new deep learning (DRL) framework for resource allocation and optimization in cloud computing. The proposed method leverages the multi-agent DRL architecture to address extensive decision-making processes in large cloud environments. We formulate the problem based on Markov's decision, creating a state space that includes the use of resources, work characteristics, and energy. The workspace comprises VM placement, migration, and physical power state determination. Careful reward work balances energy, efficiency, and resource utilization goals. We modify the Proximal Policy Optimization algorithm to handle the heterogeneous workspace and include advanced training techniques such as priority recursion and learning data. Simulations using real-world signals show that our method outperforms conventional and single-agent DRL methods, achieving a 25% reduction in the usage of electricity while maintaining a 2.5% SLA violation. The framework is adaptable to different work patterns and scales well to large data set environments. A global study further proves the proposal's validity, showing a significant improvement in energy consumption and efficiency compared to commercial management systems already there.

Authors: Zozulinskyy Andriy
Published: October 2024

The Russo-Ukrainian War, which began in February 2022, has had profound and far-reaching effects in Ukraine directly involved and the global community at large. The conflict has triggered a wide range of financial, economic and social consequences that have been the subject of extensive academic and policy-oriented research. Current bibliometric studies often focus on specific disciplines, such as finance, economics, sociology, or political science, without fully integrating findings across these fields. There is a need for more comprehensive analyses that consider the interdisciplinary nature of the war’s consequences, highlighting connections between financial, economic, and social impacts. Addressing these gaps would enhance the utility of bibliometric analysis in understanding the multifaceted consequences of the Russo-Ukrainian War, providing a more holistic view of its impact on global financial markets, society, economy, and governance. Scopus database was used for data collection. The sample documents were selected from publications released between 2022 and the first half of 2024. According to Biblioshiny, these publications involved 2860 unique authors, the number of publication is increasing ( in 2022, 159 documents were published, in 2023 – 483, and the first half of 2024 – 306). The most publications are published in scientific journals specializing in energy topics, a significant volume of publications belongs to journals with financial specialization. International co-authorships account for 27,53%, indicating that more than one in four articles is the result of collaborative research of authors from different countries. Authors from top countries (10 and more publications) published documents in the topic only in collaboration with authors from other countries. Ukraine leads in the number of publications, contributing 10,2% of the total, with China, USA, Poland, and Italy also being in the top 5, together accounting for 30,3% of all publications. There are eight Ukrainian institutions among the top affiliated institutes. The literature provides valuable insights into the immediate and long-term impacts of the conflict, highlighting the challenges faced by Ukraine and the global community. As the war continues to evolve, ongoing research will be essential to understanding its full impact and to guiding the international response in addressing the consequences of this devastating conflict.

The study uses daily price and volume data from an extensive dataset spanning from 2016 to 2023, focusing on the year 2022 to analyze trends and relationships between Ethereum’s price, market volume, and time. Employing correlation and regression analyses, the study aims to identify key patterns, with a focus on understanding how these variables interact within the volatile cryptocurrency market. The methodology centres on refining the data to ensure accuracy and integrity, including the removal of outliers and verification of variable distributions. Correlation analysis was conducted to explore the relationships between price, volume, and time. Regression analysis further assessed the impact of volume and temporal factors on Ethereum’s price, using heteroskedasticity-consistent standard errors to address market volatility. The model’s robustness was validated through statistical significance tests, and visualizations were used to present data trends and relationships effectively. The findings reveal that Ethereum experienced substantial volatility in 2022, characterized by a general downward price trend. The study identified a weak inverse correlation between price and trading volume, suggesting that periods of higher trading activity often coincide with lower prices, possibly reflecting market corrections or sell-offs. The regression analysis indicated that time is a significant factor in Ethereum’s price dynamics, with a strong positive correlation between the observation order and price, highlighting a clear downward trend over the year. The model demonstrated a high explanatory power, with an Adjusted R-squared of 83.94%, indicating that the selected variables effectively capture the variance in price. The discussion places these findings within the broader context of market developments, including technological shifts like Ethereum 2.0, regulatory changes, and macroeconomic factors that shaped the price movements. The inverse relationship between volume and price underscores the impact of trading behaviour on market sentiment, while the downward temporal trend aligns with the overall market downturn seen in 2022. Despite short-term negative trends, the analysis underscores Ethereum’s long-term potential, given its leading role in decentralized finance, non-fungible tokens, and blockchain innovation. This research remains highly relevant as it addresses the interplay of technical, market, and macroeconomic factors in shaping Ethereum’s price and market prospects, providing a framework for understanding its future trajectory within the evolving cryptocurrency landscape.

Authors: Chohra Mohamed
Published: October 2024

The management of socio-economic infrastructure projects in developing countries, including roads, bridges, tunnels, railways, ports, airports, dams and others, presents multifaceted challenges, particularly in environments marked by complexity and uncertainty. Despite the efforts of governments in these countries, these types of projects still face numerous risks, including political, technological, regulatory, financial, and market risks. The objective of the study was to examine the practices related to the problem of the decision-making process and risk assessment in the management of socio-economic infrastructure projects in developing countries, focusing on the example of the Algerian experience. This research used a qualitative analysis of the decision-making process through 15 semi-structured interviews conducted with representatives of various institutions and administrations responsible for supervising the East-West highway project in Algeria and several focus groups conducted or observations noted at the meetings where the author participated as a principal engineer at the Ministry of Public Works (project owner) during the different phases of the implementation of this mega-project. This made it possible to carry out a global assessment of current practices and to identify the major risks that can impact the decision-making process to improve the management of socio-economic infrastructure projects in Algeria and also in developing countries. The results of the study reveal the risks related to the complexity of the external and internal environment of the projects, in which among the 13 major risks identified, 61.54% have a high criticality, 30.77% have a medium criticality, and 7.69% have a low criticality. The results show that several important aspects need to be improved, including: 1) strengthening financial stability; 2) political risk mitigation; 3) implementing economic stability measures; 4) clarifying contractual aspects; 5) promoting cultural sensitivity and communication; 6) improving cost and quality control measures. This study provides valuable guidance to governments, businesses, managers, and other individuals or groups interested in promoting the management of socio-economic infrastructure projects in developing countries.
Fighting Fire with Fire: Reclaiming Social Media to Promote Healthy Eating Behaviors among Children
Authors: George Babu , Ravola Martha
Published: October 2024

Social media’s pervasive influence on children’s eating habits presents both challenges and opportunities in addressing the global childhood obesity crisis. This paper examines the complex interplay between social media exposure and children’s dietary behaviors, proposing innovative strategies to leverage these platforms to promote healthy eating. The literature review reveals that while social media often contributes to unhealthy food choices through targeted advertising and unrealistic body ideals, it also offers unique potential for positive behavior change. The paper analyzes the psychological and social vulnerabilities that make children susceptible to unhealthy food marketing on social media, as well as the long-term health consequences of poor dietary habits established in childhood. Building upon current theoretical frameworks, including the Health Belief Model, the Social Cognitive Theory, and the Transtheoretical Model, the concept “Model of Health Behavior Transformation with Social Media as the Catalyst” is proposed. This model integrates key constructs such as social media exposure, social cognitive factors, motivational elements, and behavioral outcomes to guide effective interventions. The best practices are outlined for leveraging social media to promote healthy eating, including tailored content creation, strategic use of influencers, gamification, and interactive elements. The paper emphasizes the importance of ethical considerations in implementing social media interventions for children, addressing privacy concerns, data security, and the need for age-appropriate, culturally sensitive content. This research highlights the potential of integrating social media strategies with traditional health promotion approaches, calling for collaboration among policymakers, healthcare professionals, educators, and social media platforms. By providing actionable strategies and a theoretical framework, this paper offers guidance for stakeholders seeking to combat childhood obesity and promote lifelong healthy eating habits. Key areas for future research are identified, including the long-term efficacy of social media interventions, culturally adaptive messaging strategies, and the role of emerging technologies in health promotion for children. This comprehensive approach to reclaiming social media as a tool for positive health behavior change has implications for public health policy, childhood obesity prevention, and the overall well-being of future generations.

Unraveling the Impact of Oil Price Fluctuations on Economic Growth: VAR Analysis and Causality Testing
Authors: Hadji Youssouf , Ben Abderrahmane Abdessamed
Published: October 2024

This study investigates the complex relationship between oil price fluctuations and economic growth in Algeria, using time series data from 1973 to 2023. Advanced econometric techniques, including Vector Autoregression (VAR), Impulse Response Functions (IRFs), Variance Decomposition (VD), and the Toda-Yamamoto causality test, were employed to examine both the direct and indirect effects of oil price changes on the country’s growth. The results of the VAR model indicate a strong positive relationship between oil prices and economic growth, emphasizing the critical role of hydrocarbon exports in driving Algeria’s economy. However, this connection is influenced by other macroeconomic factors, such as inflation, exchange rates, and money supply. IRF analysis shows that while oil price increases initially stimulate growth, long-term impacts are moderated by adjustments in monetary policy and exchange rates. The variance decomposition analysis further highlights that oil price volatility significantly influences short-term economic performance, but its effect diminishes over time, suggesting progress in economic diversification, policy adaptation, and the effectiveness of managing oil-related volatility. The Toda-Yamamoto causality test provides additional insights, confirming unidirectional causality from oil prices to growth and highlighting indirect effects through exchange rates and money supply. These findings underscore the importance of continued diversification efforts in oil-dependent economies like Algeria, as well as the need for adaptive monetary and exchange rate policies to ensure both short-term stability and long-term growth. This study contributes to the broader literature on oil price-growth dynamics and offers valuable guidance for policymakers in resource-rich countries.
