Metaheuristic-based optimal energy assessment of hybrid multi-effect evaporator with synergy of solar and wind energy sources
No full textThis study emphasizes a multi-pronged approach to improving the energy efficiency of Multi-Effect Evaporator (MEE) in the paper industry. By incorporating traditional Energy-Saving Schemes (ESSs) and innovative renewable energy sources, the study demonstrates significant potential for reducing energy consumption and environmental impact, making it a decisive pathway for industrial sustainability. Key ESS strategies include Thermo-Vapor Compressors, Feed Preheaters, and Steam- and Feed-Split, which are employed to enhance Steam Economy (SE) to evaluate MEE efficiency. This integration results in a 67.93% enhancement in SE, reducing energy consumption significantly. Further, SE enhancement is achieved by integrating flash tanks that capture and reuse excess heat, which boosts SE by an additional 5.89%, leading to a total improvement of 73% without additional energy consumption. A significant innovation in the study is the integration of Linear Fresnel Reflectors (LFRs) based solar collectors and turbine-based wind energy sources to power the MEE and reduce reliance on conventional energy. This hybrid system decreases energy dependence by 62% for the base MEE and 34% for the hybrid MEE. The results are validated by comparing them with existing studies, confirming the effectiveness of the proposed method and offering significant energy and environment savings
Detecting hate in diversity: a survey of multilingual code-mixed image and video analysis
Full text linkThe proliferation of damaging content on social media in today’s digital environment has increased the need for efficient hate speech identification systems. A thorough examination of hate speech detection methods in a variety of settings, such as code-mixed, multilingual, visual, audio, and textual scenarios, is presented in this paper. Unlike previous research focusing on single modalities, our study thoroughly examines hate speech identification across multiple forms. We classify the numerous types of hate speech, showing how it appears on different platforms and emphasizing the unique difficulties in multi-modal and multilingual settings. We fill research gaps by assessing a variety of methods, including deep learning, machine learning, and natural language processing, especially for complicated data like code-mixed and cross-lingual text. Additionally, we offer key technique comparisons, suggesting future research avenues that prioritize multi-modal analysis and ethical data handling, while acknowledging its benefits and drawbacks. This study attempts to promote scholarly research and real-world applications on social media platforms by acting as an essential resource for improving hate speech identification across various data sources

Los resultados mostraron una correlación prácticamente perfecta (R > 0,9) entre los encoders ADR e Ivolution en todas las intensidades, con un sesgo sistemático bajo (<0,05 m/s) según los gráficos de Bland-Altman. Además, el encoder Ivolution demostró una alta fiabilidad, con un coeficiente de correlación intraclase (ICC) por encima de 0,8 en todas las intensidades, siendo mayor a intensidades más bajas. En conclusión, el encoder Ivolution es un dispositivo válido y fiable para medir la velocidad media de la barra durante el press de banca en máquina Smith
What works in financial education? Experimental evidence on program impact
Full text linkFinancial education is increasingly essential for safeguarding both individual and corporate well-being. This study systematically reviews global financial education experiments using a dual-method framework that integrates a deep learning classifier with advanced multivariate statistical techniques. Our analysis indicates that while short-term improvements in financial literacy are common, such gains tend to diminish over time without ongoing reinforcement. Moreover, the limited impact of digital innovations and monetary incentives suggests that successful financial education depends on more than simply deploying technological solutions or extrinsic rewards. Overall, this review provides valuable insights into the evolving landscape of financial education in a dynamic economic context and underscores the need for sustainable strategies that secure lasting improvements in financial literacy
Exploring the nexus: Hausman test application in tourism, globalization, and environmental sustainability- evidence of top 10 visited countries
Full text linkEconometric analysis has long been integral to measuring sustainable environmental quality, with panel data methods, such as fixed and random effects models, becoming the focal point of modern research. Initially, such methods were used to simply investigate environmental issues, but recent years have seen a shift toward the study of random effects models, focusing on hypothesis testing and policy debates. However, several important aspects of the Hausman test have not been sufficiently investigated in the literature. This study seeks to evaluate the utility of the Hausman test using a real dataset from tourism and globalization, exploring their effects on sustainable environmental quality. Additionally, the study examines key factors contributing to environmental issues including economic growth and energy consumption, as critical explanatory variables. By investigating the relationship between tourism, globalization, economic growth, and energy use, the research focuses on the top 10 most visited economies: France, the USA, Spain, China, Turkey, Italy, Mexico, Germany, Thailand, and the UK. Using panel data and the cross-sectional random effects model for the period of 1998 to 2024, the study produces reliable estimations of these relationships. The empirical findings suggest that while the Hausman test favors the fixed effect model, the real-world characteristics of these countries point to the random effect model, highlighting the negative impact of economic growth, energy consumption, and globalization on sustainable environmental quality. It is also suggested that socio-environmental factors should be considered for each destination for sustainable environmental quality

Análise da aplicação do Direito penal na repressão de crimes por danos materiais em manifestações populares: um estudo no contexto de Luanda (2019 – 2024) no âmbito do sistema de justiça criminal angolano.
No full textO presente trabalho, intitulado “Análise da Aplicação do Direito Penal na Repressão
de Crimes por Danos Materiais em Manifestações Populares: Um Estudo do
Contexto de Luanda (2019–2024) no Âmbito do Sistema de Justiça Criminal
Angolano”, tem como objetivo examinar a forma como o sistema de justiça penal
angolano tem respondido juridicamente aos episódios de manifestações populares
ocorridos em Luanda, nos quais se verificaram danos materiais. A pesquisa
fundamenta-se numa abordagem mista, descritiva, analítica e exploratória,
combinando análise teórica das normas penais e processuais com observações
empíricas sobre a atuação das autoridades policiais e judiciais no período em
estudo. Pretende-se compreender se a aplicação do Direito Penal, nesses casos,
tem respeitado os princípios da proporcionalidade, legalidade, seletividade e tutela
efetiva dos bens jurídicos, especialmente o património público e privado. Os
resultados apontam para uma tendência de repressão penal seletiva, onde a
resposta do Estado, por meio das instituições de justiça criminal, revela tensões
entre a defesa da ordem pública e a salvaguarda dos direitos fundamentais dos
cidadãos. A análise demonstra que, embora a proteção do património seja um dever
jurídico legítimo, a instrumentalização do Direito Penal em contextos de protesto
pode fragilizar o Estado Democrático de Direito, quando aplicada de modo
desproporcional ou politizado. Conclui-se que a consolidação de uma justiça penal
verdadeiramente democrática em Angola exige o fortalecimento das garantias
processuais, a formação ética dos operadores do Direito e a promoção de uma
cultura jurídica voltada para o equilíbrio entre segurança pública e liberdade cívica
External Load Variability in Elite Futsal: Positional Demands and Microcycle Structuring for Player Well-Being and Performance
No full textThe aim of this study was to compare the external load of each session along competitive microcycles on an elite futsal team, considering the positions and relationships of the players. The external load of 10 elite players from a First Division team in the Spanish Futsal League (age 27.5 ± 7 years, height 1.73 ± 0.05 m, weight 70.1 ± 3.8 kg) were recorded across 30 microcycles. The players’ external loads were monitored using OLIVER devices. To analyse the external load, Levene’s test was conducted to assess the homogeneity of variances, followed by one-way analysis of variance (ANOVA) to identify differences in dependent variables across the different microcycle days and player positions. Regarding external load during the microcycle, the day with the lowest external load was MD-1, and the days with the highest external load were MD-3 and MD-4. In addition, considering playing positions, pivots exhibited the lowest loads throughout the microcycle, whereas wingers and defenders exhibited the highest loads, depending on the variables analysed. By providing reference values from elite contexts, this study offers practical insights for S&C coaches to optimize microcycles. Furthermore, it contributes to workload management strategies within sport science and public health frameworks, promoting sustainable performance and athlete wellness in futsal
Antimicrobial resistant enteric bacteria are widely distributed among environmental water sources in Dhaka, Bangladesh
No full textDisposal of antibiotics and antimicrobial-resistant enteric bacteria (ARB) into water from various sources is responsible for maintaining ARB in the environment. Relative prevalence and circulation of ARB may vary across water sources. We hypothesized that these ARBs with different resistance genes are distributed in various freshwater sources and are related to each other. We screened 155 enteric bacterial isolates from eight different water sources in Dhaka. The prevalence of ARB and MDR enteric bacteria in water was significantly associated (p value < 0.05) with the sources. The genotypic analysis of blaTEM, qnrB, tetA, mcr-1, and sul-1 revealed higher similarity of the isolates from freshwater with previously reported isolates from clinical samples. Water sources with direct exposure to antibiotics had a significantly higher frequency of genotypic and phenotypic resistance. This study calls for continuous monitoring of water sources and strengthening the treatment of antibiotic and ARB-containing effluents in Bangladesh
