PRODUÇÃO DE PÓ DE VIDRO MOÍDO A PARTIR DE RESÍDUOS PARA APLICAÇÃO EM OBRAS DE INFRAESTUTURA
Authors: DORNELLES LUCAS EDUARDO , CORREA BETHANIA
Published: October 2024

Em um contexto de desenvolvimento sustentável, a utilização de materiais alternativos para o melhoramento de solos em obras de infraestrutura tem se mostrado uma excelente alternativa. Neste panorama, este trabalho teve como objetivo a produção de pó de vidro moído obtido a partir de resíduos, visando a sua aplicação como material cimentante em camadas de solos de obras de infraestrutura. O pó de vidro pode ser obtido a partir dos processos de moagem, trituração e peneiramento de vidro de descartes, como garrafas não-retornáveis e vidros planos. No estudo, optou-se pela avaliação da estabilização de um solo residual argiloso com o uso de pó de vidro moído e adição de cal de carbureto, resíduo gerado na produção industrial do gás acetileno. O pó de vidro foi produzido a partir de vidro de garrafas não retornáveis. Em laboratório, corpos-de-prova foram moldados com as adições e posteriormente ensaiados no ensaio de compressão diametral. A partir dos resultados obtidos, foi possível identificar que a utilização do pó de vidro, aliado a adição de cal de carbureto, permite a obtenção de materiais mais resistentes. Assim, conclui-se que a estabilização de solos com resíduos, como o pó de vidro moído, é uma alternativa viável para diversas obras de infraestrutura, como camadas de suporte para fundações de obras de arte especiais, proteção de taludes rodoviários e em camadas de pavimentos rodoviários e ferroviários.

Visando o uso de práticas sustentáveis, o material fresado de pavimento, ou RAP (Reclaimed Asphalt Pavement), pode ser reutilizado na produção de materiais estabilizados com emulsão de asfalto (Bitumen Stabilized Materials – BSM), possibilitando seu retorno à rodovia. A BSM vem ganhando espaço no Brasil e auxilia na redução da pegada ambiental por ser um material de aplicação a frio e com possibilidade de incorporação de elevados valores de RAP. Este trabalho objetiva quantificar os impactos ambientais oriundos da produção de BSM, a partir de uma análise de ciclo de vida, visando identificar oportunidades de melhoria do desempenho ambiental de seu processo produtivo. Para tanto, utilizou-se o software OpenLCA e a base de dados Ecoinvent 3.7.1, estando o escopo restrito aos módulos A1, A2 e A3, correspondente à fase de produção dos materiais, conforme proposto pela norma ISO 21930 (2017). O método utilizado foi o ReCiPe endpoint (H, A), cujos indicadores apresentam os impactos ambientais agregados nas categorias de saúde humana, biodiversidade e escassez de recursos. Os resultados demonstraram que o esgotamento de combustíveis fósseis, devido majoritariamente ao transporte de materiais, é o principal impacto ambiental da BSM analisada. Assim, verifica-se também que os impactos estão diretamente relacionados à emissão de CO2. Portanto, uma oportunidade de melhorar o desempenho ambiental da produção de BSM é a alternância para combustíveis oriundos de fontes renováveis, utilização de bioligantes ou a substituição da frota de veículos antigos por novos menos poluentes.

O transporte rodoviário é o principal modo de transporte utilizado no Brasil e evolui em conjunto com o desenvolvimento do país. Com isso, é importante que as rodovias estejam adequadas para oferecer conforto e segurança aos usuários. Uma das formas de avaliar se determinada via está com as condições satisfatórias de rolamento é por meio do Índice de Gravidade Global - IGG. Diante do exposto, o presente trabalho tem como objetivo caracterizar a condição da superfície de um trecho de pavimento flexível de uma rodovia localizada no município de Quixadá-CE. Realizou-se um levantamento dos defeitos em 50 estações, obtendo-se um conceito ruim para toda a sua extensão. Esse resultado é devido à grande quantidade de defeitos, principalmente remendos, que foram encontrados em 66% das amostras. Além disso, foram verificadas panelas, fissuras, trincas longitudinais longas e curtas, trincas transversais longas e curtas, trincas do tipo couro de jacaré com e sem erosão, do tipo bloco com erosão, afundamentos plásticos e consolidados locais. Concluiu-se que a rodovia necessita de um reforço ou reconstrução, sendo necessária uma avaliação estrutural para complementar a sua análise completa.

A esporotricose é uma micose cutânea causada pelo fungo Sporothrix schenckii o qual pode infectar diferentes espécies animais e os seres humanos podem ser incluídos no ciclo do parasita. Os gatos do presente estudo tinham acima de um ano de idade, SRD, machos inteiros e castrados, domiciliado e também com acesso à rua. Apresentavam histórico de lesões cutânea ulcerativa aproximadamente de três meses a mais em várias regiões do corpo. O tratamento de escolha foi o intraconazol na dose de l0 mg/Kg, por via oral, administrado por um período de 30 dias ou mais, sendo muito bem tolerado por esses animais. Diante do risco de transmissão aos seres humanos, somente o primeiro animal foi tratado com o medicamento de escolha, sendo os demais eutanasiados. Considerando o potencial de transmissão da zoonose, a letalidade e o contato humano com animais de estimação são imprescindíveis que o médico veterinário esteja preparado para diagnosticar a doença e repassar informações à população sobre a forma de transmissão, profilaxia, sintomas e ações a serem tomadas.

Situações estressantes e dolorosas podem alterar a secreção dos hormônios hipofisários que regulam diretamente as funções relacionadas ao bem-estar do animal. Os efeitos terapêuticos do sangue têm sido atribuídos em parte às plaquetas, importante na reparação tecidual. Para diminuir o estresse fisiológico, a utilização do tramadol na prática hospitalar tem sido importante em animais, que tornam relevantes o uso desse fármaco em pesquisas. Foram selecionadas 30 fêmeas adultas da espécie canina, clinicamente hígidas, distribuídos aleatoriamente em três grupos. Foi mensurada temperatura retal, frequência cardíaca, frequência respiratória e dosagem do cortisol sérico em cinco momentos. A técnica cirúrgica adotada foi a ovariosalpingohisterectomia. Os níveis de cortisol sérico foram semelhantes em todos os momentos entre os grupos não havendo elevação. A aplicação do tramadol em cadelas submetidas à cirurgia não alterou as variáveis fisiológicas, no pré e pós-operatório, assim como o uso de células sanguíneas, podendo ainda ser usada como alternativa terapêutica na reparação tecidual.

Revision and the Politics of Truth-Telling in the Autobiography of Juan Francisco Manzano
Authors: Carroll Ryan
Published: October 2024

Abstract: This essay examines a text that is a site of complex revisional practice: the Cuban poet Juan Francisco Manzano's Autobiografía del esclavo poeta , first published in English as Poems by a Slave (1840). The text seems to attest to the way that truth-telling practices figured into abolitionist political networks in and beyond Britain—seeming to mesh with the truth-telling impulse to undiscipline Victorian studies. But its formal variations, from Manzano's storytelling to Madden's editorialization, problematize the very possibility of truth-telling under slavocracy. Ultimately, reading this text's variable form can shed light on Manzano's critical activity and allow us, as scholars, to consider the problematics of telling truth under white supremacy.

Published: October 2024

Although digital technology and democracy through digital learning environments are gaining attention in applied linguistics, the lack of a measurement scale with robust psychometric properties hinders progress towards education quality   and learning opportunities. To address this gap, this study is a report on designing, constructing, and validating the practicality of critical digital pedagogy (CDP) scale. To undertake the study, a quantitative research following a survey design was adopted to (a) develop and validate the scale, and (b) to screen English as a foreign language (EFL) teachers’ perceptions. To gauge teachers’ perspectives, this study aimed to conceptualize the construct of CDP through the development and validation of a scale specifically designed for use in online classrooms. Utilizing both data-driven and theoretical approaches among 412 EFL teachers has resulted in the development of a 27-item CDP scale. Notably, the findings indicated a high level of internal consistency and satisfactory construct validity of the of the newly developed scale. Such scale can bridge the gap between critical pedagogy and digital instruction.

Authors: Yifan Pang  , Hashim Harwati , Said Nur Ehsan Mohd
Published: October 2024

Embarking on the journey of learning Chinese as a foreign language in college entails grappling with a myriad of distinctive challenges, ranging from navigating its intricate writing system to mastering its tonal pronunciation and unraveling its rich cultural nuances. In this complex landscape of language acquisition, comprehending the nuanced learning strategies wielded by Chinese foreign language learners becomes paramount. These strategies not only illuminate the pathways to effective teaching but also hold the key to enhancing student outcomes. Despite the burgeoning interest in Chinese language education, there exists a conspicuous dearth of qualitative studies delving into the intricacies of learning strategies within college settings. To address this gap, this study adopts a qualitative research paradigm, employing semi-structured interviews as its methodological backbone. Through these interviews, the study endeavors to excavate profound insights into the diverse repertoire of learning strategies embraced by Chinese foreign language learners in the collegiate milieu. At its core, the study's primary objective is twofold: to meticulously explore and rigorously analyze the spectrum of learning strategies woven into the fabric of Chinese foreign language learning at the college level. By peering into the multifaceted approaches employed by students, the study aspires to engender a nuanced comprehension of effective pedagogical methodologies. Moreover, the findings are poised to serve as a compass, guiding the design and implementation of tailored language learning interventions tailored to the unique needs and aspirations of Chinese language learners in college environments.
Trend Analysis of Fluency-Related Research Articles: Using Data Mining
Authors: Park Shinjae
Published: October 2024

This research seeks to identify recent research trends in analysing fluency in English language studies since 2010. The importance of studying corpora that compile registered research in linguistics is growing; thus, it is time to consider the significance of data mining analysis on the corpora. Considering this emerging research topic, this analysis intends to generate and compare word clouds and word metric charts from speaking and writing abstract corpora in linguistics research centred on the keyword ‘Fluency’. This comparison is minimally addressed in extant research; hence, this investigation aims to fill this gap. The corpus contains 50 speaking and 15 writing abstracts from linguistics journals. To create the word cloud, AntConc4.1.4 software was used to analyse the corpora, while TF-IDF and matrix analysis were conducted using R. As a result, in spoken English, ‘fluency’ studies were largely related to 'teaching' and tended to be dominated by studies focusing on ‘fluency’ alone. In contrast, writing studies were mostly related to learner proficiency and assessment, and many studies analysed the relationship between linguistic abilities by expanding the scope of ‘fluency’ to include ‘accuracy’ and ‘complexity’. This study will benefit researchers in deciding on topics as it provides research directions and trends in analysing fluency in the two interconnected but differently expressed fields (i.e., speaking and writing).
Cardioprotective effects of novel antioxidants post-myocardial infarction: An integrative review of preclinical and clinical data
Authors: Soufia Elmahroug  , Yussef Elmahroug
Published: October 2024

Myocardial infarction (MI), is still a major public health problem, and oxidative stress contributes to the degree of myocardial damage after MI. Oxygen-derived free radicals (ODFR) worsen myocardial injury and result in chronic heart failure in many patients. These harms have led to interest in antioxidant treatment to reduce these adverse effects; new antioxidants with the potential for cardioprotection are the subject of significant interest. This review summarizes basic and clinical research comparing the effectiveness of newly synthesized antioxidants in attenuating oxidative stress and enhancing recovery after myocardial infarction. The review synthesizes evidence of a reduction in infarct size, enhancement of cardiac function, and repression of apoptosis in myocardial cells by the use of antioxidants from animal models. Melatonin, N-acetylcysteine, edaravone, and coenzyme Q10 demonstrated a wide range of preclinical positive effects by acting as ROS free radicals scavengers, modulating mitochondria dysfunction, and reducing inflammation. These findings are extrapolated from humans, although advances in antioxidant therapy are beginning to be viewed in initial clinical trials. From human data, although clinical trials are scarce, the evidence of new antioxidants can improve point and long-term outcomes in patients undergoing MI, help to increase the contractility of the injured myocardium, and decrease the mortality level. However, some issues are still there, such as high inter- and intra-individual variability in patient response and dosing schedule, as well as adverse effects such as pro-oxidant activity at high Oral administered doses of melatonin. The limitations of the current research discussed in this review include the general lack of large-scale, well-controlled clinical trials and the need for long-term follow-up studies. This review also proposed future research directions for improving antioxidant applications in post-MI management.

Gold price fluctuations have a significant impact because gold is a haven asset. When financial markets are volatile, investors tend to turn to safer instruments such as gold, so gold price forecasting becomes important in economic uncertainty. The novelty of this research is the comparative analysis of time series forecasting models using ARIMA and the NNAR methods to predict gold price movements specifically applied to gold price data with non-stationary and non-linear characteristics. The aim is to identify the strengths and limitations of ARIMA and NNAR on such data. ARIMA can only be applied to time series data that are already stationary or have been converted to stationary form through differentiation. However, ARIMA may struggle to capture complex non-linear patterns in non-stationary data. Instead, NNAR can handle non-stationary data more effectively by modeling the complex non-linear relationships between input and output variables. In the NNAR model, the lag values of the time series are used as input variables for the neural network. The dataset used is the closing price of gold with 1449 periods from January 2, 2018, to October 5, 2023. The augmented Dickey-Fuller test dataset obtained a p-value = 0.6746, meaning the data is not stationary. The ARIMA(1, 1, 1) model was selected as the gold price forecasting model and outperformed other candidate ARIMA models based on parameter identification and model diagnosis tests. Model performance is evaluated based on the RMSE and MAE values. In this study, the ARIMA(1, 1, 1) model obtained RMSE = 16.20431 and MAE = 11.13958. The NNAR(1, 10) model produces RMSE = 16.10002 and MAE = 11.09360. Based on the RMSE and MAE values, the NNAR(1, 10) model produces better accuracy than the ARIMA(1, 1, 1) model.

Published: October 2024

Gymnostoma sumatranum, a member of the Casuarinaceae family, is a resilient tree species well-adapted to nutrient-deficient soils. In Sabah, it stands out among the three widely distributed Casuarinaceae species, holding promise for land reclamation initiatives in degraded ultramafic forests. This comprehensive study addresses three primary objectives for effective G. sumatranum propagation, 1) sprig selection for rooted cutting, 2) impact of commercial rooting hormones on growth and nodulation, and 3) identification of suitable potting media for seedling development. The results indicated that the middle-part sprig is preferable for rooted cutting, with a higher rooting percentage (75.9%) compared to the upper-part sprig (57.5%). Additionally, the use of Seradix-3 as a growth hormone treatment yields significant improvements in explant length and root production. However, variations in root nodulation, influenced by different treatments, suggested limitations in commercial rooting hormones, with only 31% of rooted explants exhibiting nodulation. This underscores the need for further research to comprehend factors influencing nodulation in this context. In terms of potting media, river sand (R-sand) emerges as the most effective for G. sumatranum seedling development in the nursery stage based on S-index (healthy seedlings = 31.5%) and growth index (Height = 51.14±14.82 mm; N-Branch = 51.14±14.82), emphasising the critical role of proper potting medium selection for optimal seedling growth and survival. The study also highlights previous restoration efforts by the Sabah Forestry Department, utilising G. sumatranum and other pioneer species to restore degraded ultramafic areas in Sabah. Overall, these results contribute to the long-term goal of restoring the functioning capacity of valuable ultramafic ecosystems and promoting sustainable reforestation practices.

This study investigated heavy metal contamination around an industrial district in Obajana, Southwest Nigeria. The study region lies between latitudes 7°54′N to 7°56′N and longitudes 6°24′E to 6°27′E. Thirty samples each for groundwater and soil and twelve plant samples were collected from the study area. All samples were collected in triplicate. The physical and chemical parameters of the groundwater, soil, and plant samples were measured. The average pH level of the groundwater samples is 7.2 which falls within the Nigerian Standards for Drinking Water Quality (NSDWQ). The ranges of the other physical parameterssuch as electrical conductivity (EC), total dissolved solids (TDS) and total hardness (TH) are also within the acceptable limits. The mean concentrations of heavy metals in groundwater samples for Mn (0.020 mg/L), Zn (0.010 mg/L), Ni (0.010 mg/L), Cr (0.130 mg/L), Cu (0.020 mg/L), and Fe (0.090 mg/L) are within the allowable limit, with the exception of Pb (0.090 mg/L) that is above the recommended level. According to the index of geo-accumulation (Igeo), the soil and plant samples are not polluted with respect to the heavy metals tested. The analysis of the human risk assessment reveals that the values for the carcinogenic risk are within acceptable bounds; however, the values for the non-carcinogenic risk are substantially above the acceptable bounds. This demonstrates that non-carcinogenic health impacts are a threat to the broader population. This study suggests continuous monitoring of groundwater, soil, and plant in the study area.

Published: October 2024

Commercial rabbit farming is primarily focused on the production of rabbit meat, although the presence of gastrointestinal disorders can impede their productivity. Endoparasites significantly contribute to the development of several diseases in rabbits, leading to higher rates of illness and death. Passalurus ambiguus is a widely distributed nematode that commonly infects the intestines of rabbits and hares. Parasitic disease can have a substantial economic impact on the industry by reducing the commercial value of rabbit meat and skins, impeding growth and development, and leading to mortality. This study aims to examine the frequency of gastrointestinal parasites in domestic rabbits that are bred in Karbala province, Iraq. Throughout the trial, fecal samples were collected from a randomly selected group of 48 live rabbits. The feces are collected directly from the anus of each living animal. The samples were tested and the presence of eggs and nematodes was detected in the infected samples. Analysis of samples was carried out at the Parasitology Laboratory, college of Veterinary Medicine, Kerbala university, using the flotation technique. Feces from 48 rabbits (ages 1-2) years. The feces are taken out of each animal directly from the anus. Upon testing, it was found that 16 out of 48 fecal samples, accounting for a prevalence of 33.33 %, were infected with at least one nematode. Chi-square (χ2) statistics. Age and genders are not statistically significant at P values ≥ 0.05. This study identified the presence of Passalurus ambiguus in rabbits of varying ages residing in Karbala region, Iraq, including both male and female domestic rabbits. Determining the age and gender of rabbits affected by passalurosis would enable the management of the infection level in these animals. Regular use of a consistent and dependable diagnostic method is essential in industrial rabbit farms to detect and monitor gastrointestinal parasite illnesses. Gastrointestinal parasites continue to be significant health issues that lead to the mortality of rabbit litters in production. Stress and a reduction in immune response may be crucial factors driving this phenomenon.
Bioelectric Characterization of Senescing Human Keratinocytes
Authors: Sediqi Hamid , Levin Michael
Published: October 2024

Aging, a ubiquitous process that affects almost all multicellular organisms, is accompanied by the accumulation of senescent cells, leading to a decline of morphology and function. The ‘loss of morphostatic information’ theory posits that aging occurs due to gradual breakdown of order initially established during embryo development. Spatial differences in cellular resting potential have many roles in organizing cell activity into complex anatomical structures during embryogenesis and regeneration. Thus, while bioelectric patterns are a good candidate for the information that degrades during aging, long-term changes in bioelectrical state in adult cells are not well-understood. Here, we sought to characterize the temporal and spatial bioelectric dynamics of human epidermal keratinocytes undergoing replicative senescence. We stained keratinocytes of varying ages using the voltage sensitive dye – BeRST – and characterized p16 expression levels and senescence associated β-galactosidase activity. Our results revealed senescence-associated membrane depolarization – consistent change of bioelectrical potential over the lifespan of cells. Moreover, we found increased levels of Vmem heterogeneity, reduced cellular responsiveness to hyperpolarizing treatments, diminished resilience (ability to quickly and effectively achieve equilibrium post-perturbation), and degradation of bioelectricspatial organization. These results reveal a breakdown of bioelectric patterning and regulation with senescence consistent with the loss of morphostatic information theory of aging.
Can Generative AI Chatbots Emulate Human Connection? A Relationship Science Perspective
Authors: Smith Molly Grace , Bradbury Thomas , Karney Benjamin R.
Published: October 2024

The development of generative AI capable of sustaining complex conversations has created a burgeoning market for companion chatbots promising social and emotional connection. The appeal of these products raises questions about whether chatbots can fulfill the functions of close relationships. Proponents argue that relationships with chatbots can be as meaningful as relationships between humans, whereas critics argue they are a dangerous distraction from genuine connections. This analysis applies theoretical tools from over 50 years of research on close relationships to evaluate the extent to which human-chatbot interactions meet the definition of and fulfill the functions of close relationships. Interactions between humans and chatbots possess some characteristic features of close relationships: humans and chatbots can influence each other, and engage in frequent and diverse conversations over time. Chatbots can be responsive in ways humans perceive as supportive, generating feelings of connection and opportunities for growth. Yet because chatbots make only superficial requests of their users, relationships with them cannot provide the benefits of negotiating with and sacrificing for a partner, and may reinforce undesirable behaviors. Research that attends to characteristics of users, chatbots, and their interactions will be crucial for identifying for whom these relationships will be beneficial or harmful.
I Perceive, Therefore I Strive? Unraveling the Relation Between Situation Perception and Achievement Motivation States
Authors: Witte Katja , Spinath Birgit , Ziegler Matthias
Published: October 2024

Empirical evidence shows that achievement motivation is related to academic outcomeslike performance. In the last decades, research followed a more dynamic approach toexplain such connections and has shifted from using stable traits to investigatingmomentarily fluctuating states. Achievement motivation has been shown to 1) fluctuate atstate level and 2) be linked to specific situation perception variables, like Duty or Intellect,but the direction of this relation is yet unclear. Being interested in whether situationperception has an effect on achievement motivation or vice versa, we obtained state selfreportsof those variables from N = 248 students that participated in an online learningtask with three successive measurement occasions, including a quiz. Using randomintercept cross-lagged panel models, we examined the directionality of the relationbetween situation perception and achievement motivation states. Cross-lagged parameterswere mainly substantial from situation perception to motivation. There were no significantpaths for Intellect, but directional effects from Duty to achievement motivation states withpositive valence. Findings of the study highlight the importance of Duty in shapingachievement motivation states, widening our understanding of the role of situationalcontext in academic settings, and provide first insights into causal relations between thesevariables.

Pancytopenia as a result of hemophagocytosis in a middle-aged man presenting with high-grade fever of unknown etiology could be a rare consequence of Histoplasmosis infection. In the past, many cases of patients with human immunodeficiency virus infection contracting histoplasmosis-induced hemophagocytosis have been well documented, however, little data has been entered in the setting of HIV non-reactive status. Interestingly, we report a case of histoplasmosis in an immunocompetent male with the presence of yeast forms of H. capsulatum in the bone marrow smears. The patient was subsequently placed on Amphotericin B and corticosteroids but lost to the infectious disease. Cases like this, highlight the importance of taking into account the early decision for bone marrow sampling with careful attention to microscopic details as incidental pathologies may be elicited which could have significant effects on patient’s prognosis.

تتناول هذه الدراسة قراءة نقدية من خلال زاوية نظر تيار الديكولونيالية للتحولات السياسية والثقافية للإسلام السياسي في مرحلة ما بعد الأسلمة، وذلك من خلال تناول ظاهرة إسلام السوق، كما عالجها من زاوية نقدية، في البدء، الباحث في علم اجتماع الدين باتريك هايني. وترصد الاستتباعات الإبستيمولوجية لهذا النقد بناءً على منهجية العلوم الاجتماعية والإنسانية، وتبيّن أنّ هذا النقد يفرض تصوّرًا جديدًا للعلاقة بين الأخلاق الإسلامية والأخلاق الحداثية وما بعد الحداثية، التي ترتبط ارتباطًا قويًّا بقيم "المناجمنت". وهي علاقة يتضمّنها موقف إبستيمولوجي طريف، أشار إليها على نحو عميق براين تورنار في نصه النقدي لموقف ماكس فيبر Max Weber (1864–1920)، تجاه الأخلاق الإسلامية، ولموقف حركة الإصلاح الديني (الإسلامية) أيضًا التي دشّنها جمال الدين الأفغاني (1838–1897) ومحمد عبده (1849–1905). يقرّ هذا الموقف بالأهمية القصوى لفهم التحوّلات على مستوى القيم والممارسة والخطاب من خلال فهم العلاقة بين هذه التحوّلات والجانب الكولونيالي الهيمني الذي تفرضه منظومة قيم الحداثة، سواء تعلّق الأمر بقيم إبستيمية أو إيتيقية. ويفرض هذا الموقف مراجعة التصوّر الضمني الذي يُقرّ بالتطابق، أو عدم التصادم، بين الأخلاق الإسلامية والأخلاق الحداثية، لكنها مراجعة تقف على النقيض من الموقف الاستشراقي الذي يميّز بين المنظومتين ويُسقط أحكامه المعيارية الأورو-مركزية، فيوظّفها حجّةً لإثبات تخلّف الأخلاق الإسلامية. وتحاول الدراسة أيضًا رصد الصعوبات المنهجية التي تحول دون تدارك العلوم الإنسانية في العالم العربي للمواقف الأورو-مركزية تجاه القيم الأخلاقية الإسلامية. وتحاول تسليط الضوء على التحدي الفلسفي على مستوى القيم الأخلاقية الدينية، حيث يتجلّى هذا التحدي في الكيفية التي يمكن أن يقترحها النموذج الإسلامي في الأخلاق في عصر أصبح سمةً للسيولة (وهي حالة يوصّفها تيار ما بعد الحداثة) والفردانية وتحقيق الذات خارج أشكال التذوّت كلها التي تخلق حدودًا صلبة.
What Does Spirituality Look Like?
Authors: Sarracino Robert
Published: October 2024

The concept of spirituality defies a rigorous definition, much like some fundamental concepts in mathematics and physics. However, we may gain an understanding of this vital religious concept by asking what spirituality “looks like.” In this paper, following a brief overview of the concepts of spirit and spirituality in the Bahá’í writings, we examine a letter of the Universal House of Justice that gives us a picture of what spirituality should look like today, as the Bahá’í community pursues its work of creating vibrant communities. We then explore the question of whether, and to what degree, the social sciences can investigate the phenomenon of spirituality as central to human nature, arguing that they can productively adopt spiritual reality as a background assumption, whose validity can then be evaluated.
Lógica difusa como instrumento alternativo de evaluación en la educación superior en México

Published: October 2024

Introducción: La educación en México debe atender las necesidades cambiantes de la economía, debido a que casi la mitad de los empleadores alertan que en el sistema educativo existe una falta de competencias. Ante el vacío de herramientas de evaluación, este trabajo tiene el objetivo de implementar un modelo de evaluación basado en la teoría de los subconjuntos borrosos. Metodología: Fue a partir de las aportaciones de Carbal et al. (2020), quienes diseñaron un instrumento de evaluación ex post de impactos sociales. Resultados: Consistieron en adaptar los algoritmos en el ámbito educativo con los mismos principios del citado autor. Discusión: Los hallazgos están alineados con los postulados de autores relevantes, porque muestran un prototipo funcional del sistema de evaluación por valoración borrosa a la dimensión actitudinal de estudiantes universitarios. Conclusiones: El modelo propuesto responde a la falta de interés institucional en el diseño de nuevas herramientas metodológicas de evaluación que reflejen de forma más aproximada el nivel actitudinal y aptitudinal de los evaluados, debido a que las evaluaciones contienen información subjetiva. La utilización de la escala permite manejar un criterio más amplio sobre los niveles de desempeño, lo que es positivo en el aspecto motivacional del alumnado, al recibir evaluaciones integrales.

Short information on computational materials science is given, with the methodology of material properties fields, in composition and process coordinates, as the part of it and as the background of the study presented in this paper. One of the main means of the methodology is random scanning the whole and local fields. These tools were developed and used to solve many problems in materials science related to the properties defined by mutually independent factors. The purpose of the study presented in this paper has been to develop the tool for random scanning the fields of properties effected by "mixtures" of q components, linearly related portions of components in rangers from 0 to 1, with their sum equal to 1. In these cases, the factors domain (or subregion of it) presents the simplex. The special designs of experiments to get reduced polynomials describing the fields in simplex coordinates are used. Two procedures for generating any number of uniformly distributed points on the simplex have been developed. These points define the virtual mixtures simulated in computational experiments. The procedures were tested by scanning the fields of two rheological characteristics of lime suspension filled with "short", “medium", and "long" cellulose fibers. Experimental-statistical models in the form of reduced polynomials for effective viscosity at shear rate equal to1 s-1 and for the rate of destruction of liquid structure (parameters of power-law model of flow, K = η1 and m) obtained in previous study are used to determine the levels of these characteristic for each of simulated mixture. Computational experiments were carried out, in which the fields of η1 and m in whole simplex domain and in some of its zones were scanned, allowing the generalizing indices of the fields and different correlations between η1 and m in different zones of mixture triangle to be estimated. The developed tools, the procedures of generating random points, which would define the simulated compositions of the "mixtures", make significant contribution to the progress of the methodology of recipe-technological fields of properties and to computational materials science.

Solving the problem of ensuring the reliable functioning of drainage systems is important not only for Ukraine, but also for scientists around the world. Since these systems are critically important for life support, their uninterrupted operation is of strategic national importance. The issue of preservation and restoration of existing underground communications is gaining particular relevance due to increased environmental requirements. To protect groundwater from contamination with aggressive reagents, it is important to understand the reasons for the destruction of underground communications structures and effective methods of their repair. The article analyzes scientific works related to the problems of ensuring the trouble-free operation of objects that are part of the complex of constructions of sewer tunnels of the city. Grouped according to the direction of research work: research on the corrosion process in water drainage networks; analysis of modern ones; materials, laboratory tests; technologies for restoring drainage networks. Analysis of studies of the condition of structures of objects; research of materials and methods of repair and restoration of sewage tunnels and inspection shafts, which are currently used with high efficiency in domestic and foreign practice; development of technological and organizational solutions and restoration of destroyed sewage structures of drainage networks. The analysis of the researches of domestic scientists showed that the sewer tunnels of large cities of Ukraine are worn out as a result of long-term operation, ineffective solutions to protect structures from the influence of an aggressive environment, low-quality materials and structures used during construction. Restoring normative operational characteristics, increasing the durability of sewage tunnels is a costly and technically complex task, the solution of which is urgently needed to prevent accidents, including those with serious environmental consequences. Existing modern technologies of work performance, materials and structures used for repair and restoration works with different efficiency solve these problems, at the same time, the need to reduce costs for repair and restoration works requires the search for cost-effective materials, structures and methods of work performance. The analysis of the conducted studies shows that the problem of increasing the durability of sewage network structures should be solved comprehensively, taking into account the current situation.
