The Effects of Covid-19 “brain Fog” on Electrophysiological Measures of Attention and Working Memory: a P300 Study
Authors: WILSON MATTHEW J. , HILL CHRISTOPER M. , THORNTON DAVID M.
Published: February 2025

COVID-19 has led to significant global health impacts, with over 776 million confirmed cases worldwide. While it is primarily known for respiratory symptoms, COVID-19 has also been linked to cognitive impairments, particularly "brain fog," which affects attention, memory, and processing speed. The long-term effects, especially in non-hospitalized individuals, remain poorly understood.
Brain fog affects the hippocampus and prefrontal cortex, regions responsible for generating the P300, an electrophysiological measure of attention and working memory. The P300 has been used to assess cognitive deficits in various neurological conditions, though rarely in COVID-19. A dual-task paradigm, such as the n-back task, can help detect subtle cognitive impairments.
This study compared P300 responses in three groups: individuals with COVID-19 and brain fog, individuals with COVID-19 but no brain fog, and a control group (pre-pandemic). We hypothesized that the brain fog group would show reduced P300 amplitudes, especially under higher n-back loads.
Results showed that the brain fog group had smaller P300 amplitudes compared to the other two groups, regardless of task load. No significant differences were found between the brain fog negative and control groups, nor in behavioral measures. These findings suggest that the P300 is a sensitive tool for detecting subtle cognitive impairments in COVID-19 brain fog, which may not be evident in behavioral tests.

Published: February 2025

The distribution and interaction of oxygen vacancies (VOs) play a crucial role in determining the properties of metal oxides, particularly ceria, which is widely used in high-temperature industrial applications. However, information about VO behavior at high temperatures is scarce in the literature due to the inherent complexity of VO interactions and the lack of accurate models to describe and predict these interactions under such conditions. Consequently, the existence of long-range ordered Vos remains elusive. Here, we reveal an unexpected periodic one-dimensional subsurface channel induced by ordered VO distributions on CeO2 (110) at high temperatures, using in-situ scanning transmission electron microscopy (STEM), first-principles calculations, and a compressed sensing-assisted cluster expansion model. The strong repulsive interactions between neighboring VOs drive their ordered distribution, which, in turn, facilitates the formation of the periodic one-dimensional subsurface channels by relieving stresses induced by VOs and polarons. The large energy gap between the occupied O 2p band center and the unoccupied Ce 4f band center was identified to underpin these processes and maintain this abnormal subsurface channel. This subsurface channel on CeO2 (110) exhibits sub-nano-level pores and an accumulation of polarons, making it well-suited for the directional transfer of protons, which provides new insights into the high catalytic activity of ceria in hydrogenation reactions. These findings offer not only a deeper understanding of VO interactions and their underlying mechanisms but also a new approach for manipulating VOs for specialized applications.

Published: February 2025

We study the heterogeneous effects of a Swedish educational reform that increased compulsory schooling from seven to nine years. Following a pre-registered Analysis Plan, we examine how the reform differentially affected 20 outcomes in various domains (education, the labor market, fertility, substance use, and health) for individuals with different genetic propensities towards these outcomes. To estimate the effects of the reform, we leverage the gradual roll-out of the reform with a differences-in-differences estimator that compares municipalities and birth cohorts before and after the reform. Among 105 pre-registered tests of heterogeneous effects as a function of genetic propensities (across outcomes, sexes, and family SES background), we find two significant interactions after correction for multiple hypothesis testing. One of these implies that, among females from high-SES families, the reform had a relatively larger effect on earnings for those with a lower genetic propensity for educational attainment. Our results suggest that sizable heterogeneous effects of educational reforms may not be ubiquitous but do exist, and highlight how careful study designs with preregistration can help uncover them.
Photocatalytic degradation of tetracycline antibiotic using nitrogen-doped reduced graphene oxide supported by titania/platinum nanoparticles
Authors: Moharrami Elham , Keshipour Sajjad
Published: February 2025

Tetracycline, a broad-spectrum antibiotic, is particularly concerning as it is resistant to degradation in water bodies, leading to its persistence in the environment. Herein, the photocatalytic degradation of tetracycline was investigated by a newly developed catalyst of TiO2/Pt nanoparticles, which were immobilized on nitrogen-doped reduced graphene oxide (NRGO). Pt/TiO2@NRGO catalyst was prepared via a convenient pyrolytic route of mixing citric acid/urea/titanium (IV) isopropoxide as the starting materials with the subsequent deposition of Pt nanoparticles by chemical reduction of Pt (IV). Photocatalytic activity of the prepared nanocomposite was evaluated in the decomposition of tetracycline. The obtained results demonstrated the exemplary performance of the prepared heterogeneous catalyst by which the antibiotic removal efficiency was calculated to be ~ 81%. In conclusion, it can be claimed that the outstretched catalyst is able to be employed in the temperature of about 45 oC and neutral pH ranges for efficient degradation of tetracycline.
Associating Attitudes towards AI and Ambiguity: The Distinction of Acceptance and Fear of AI
Authors: Hitsuwari Jimpei , Takano Ryota
Published: February 2025

Since the emergence of ChatGPT, Artificial Intelligence (AI) has become increasingly integrated into society, making it essential to understand how individuals perceive and interact with it. Given AI’s inherent ambiguity and uncertainty, this study examines the relationship between attitudes towards AI and ambiguity. A survey of 554 Japanese participants was conducted using questionnaires, including the Attitude Toward Artificial Intelligence scale (ATAI) scale, which assesses two key dimensions: acceptance and fear, along with the Multidimensional Attitudes Toward Ambiguity Scale. Findings indicate that the Japanese version of the ATAI developed for the first time in this study, demonstrated strong internal consistency, test-retest reliability, and validity. Psychometric properties were supported by AI usage, willingness to use AI, and expected correlations with personality traits, aligning with prior literature. Text-based predictions using natural language processing reinforced this finding, showing significant associations with ATAI scores. This study is the first to examine how attitudes towards AI relate to ambiguity, revealing that Need for complexity and Novelty, and Discomfort with Ambiguity predict AI acceptance and fear. Absolutism positively correlates with both. These results indicate that attitudes towards AI are inherently complex and multidimensional, offering insights for effective and sustainable AI engagement as an ambiguous agent.

Published: February 2025

Egg size determination is an important activity in the poultry industry. Traditional methods of size assessment are labour-intensive, error-prone, and time-consuming. Machine learning is proving to be a major game changer in all sectors and this has the potential to upgrade and automate egg grading as well. Considering all this, this research was undertaken to evaluate the potential of AI-driven computer vision approaches for the extraction of egg dimensions from 2D images. The images were annotated and saved as an OBB dataset and were appropriately preprocessed. Yolo11 OBB models were evaluated for their ability to detect eggs and yolo11x-obb model was found to be optimal for this study. The Mean Absolute Errors (MAE) of the two final predictive models for egg size were 0.28 for length and 0.19 for breadth, with Pearson Correlations of 0.81 for length and 0.85 for breadth for Model 1 and MAEs of 0.29 for length and 0.26 for breadth, with Pearson Correlations of 0.88 for length and 0.81 for breadth for Model 2. Science4ImpactStatement: This foundational research concludes that Machine Learning methods can predict egg dimensions with good accuracy and could potentially be used for poultry breeding, automatic egg grading, packaging, processing as well as marketing.
Optimal Cutoff for Neutrophil-to-Lymphocyte Ratio as a Tool for Pre-Chemotherapy Prognosis Stratification of Breast Cancer Patients
Authors: Zandi Armita , Qian Alyssa , Bucciol Regan , Othman Maha
Published: February 2025

Introduction: The neutrophil-to-lymphocyte ratio (NLR) is an established inflammatory marker in cancerpatients. The optimal cut-off as an independent prognostic factor for breast cancer (BC) progression in patients undergoing chemotherapy remains debatable, hindering the effective stratification. This study explored the optimal NLR cut-off by comparing various thresholds and assessing their effectiveness in stratifying BC patients according to prognosis.
Methods: Demographic, clinical, and cancer-specific data on forty-two BC patients were recorded, including complete blood counts before and after two cycles of chemotherapy. Receiver operating characteristic curve assessed discriminatory performance. Diagnostic metrics and Youden’s J index were calculated and McNemar’s test was used to compare baseline NLR cutoffs of 2.5, 3.0, and 3.5. Kaplan-Meier curves assessed the relationship between various NLR cut-offs and other cancer prognostic markers.
Results: The three NLR cutoffs demonstrated distinct diagnostic metrics and Youden’s J index values (p < 0.001), with the 3.0 cutoff providing the most balanced performance. Patients with pre-chemotherapy NLR > 3.0 were predicted to develop advanced stage BC more rapidly compared to those with pre-chemotherapy NLR < 3.0.
Conclusion: We believe that a more stringent NLR cutoff of 3.0 is the most suitable predictor of prognosis in BC patients based on the ranges evaluated in literature.

Published: February 2025

Background: Uterine fibroids can significantly impair the quality of life of women. While most fibroids remain asymptomatic, 25% of women diagnosed with uterine fibroids require medical intervention.
Methods: A systematic review and meta-analysis protocol was developed and published in PROSPERO (CRD42022346251) to explore surgical treatment outcomes linked to uterine fibroids. Data was gathered using PubMed, Web of Science and ScienceDirect. The pooled data was analysed using the meta-package (version 8.0-1 and version 4.6-0) in R software (version 4.4.2).
Results:
Five studies met the eligibility criteria, and were further analysed to report quality of life, symptom severity and complications linked to surgery. Three studies (n=520) assessed HRQoL via UFS-QoL pre- and post-uterine artery embolisation and myomectomy. The pooled mean difference was -6.99 (95% CI: [-16.49, 2.51]; I²=71.9%; P=0.03), indicating no significant difference in quality of life impact between procedures. However, the pooled mean difference for UFS-QoL symptom severity was 4.85 (95% CI: [0.50, 9.21]; I²=0.0%; P=0.52), suggesting myomectomy significantly reduces symptom severity compared to uterine artery embolisation. Most studies did not report race and ethnicity, and the study sample was not representative of the global female populous.
Conclusion:
Uterine artery embolisation and myomectomy result in comparable improvements in health-related quality of life although myomectomy appears to offer a greater reduction in symptom severity compared to uterine artery embolisation. These findings can assist clinicians and patients make improved shared decisions when selecting the most appropriate treatment for uterine fibroids. Improved research study designs and representation in sample need to be considered when conducting future research.
Tropospheric Assessment of Carbon Monoxide, Nitrogen Dioxiode, and Aerosols in Onitsha, Anambra State, Southeastern Nigeria – a Case Study of 2019–2024
Authors: Okoye Desmond
Published: February 2025

Onitsha faces severe air pollution, exposing residents to harmful levels of carbon monoxide (CO), nitrogen dioxide (NO₂), and aerosols. This study assessed Sentinel-5P satellite data using Google Earth Engine from 2019 to 2024, analyzing pollution trends and statistical differences across the years. CO and NO₂ peaked in February, with CO highest in 2024 (0.0537 mol/m²) and lowest in 2023 (0.0481 mol/m²). NO₂ levels were highest in 2021 and 2022, while aerosols peaked in 2022 and remained high in commercial areas. Statistical analysis confirmed varying significance across years. CO levels were significantly different between 2019 and 2020 (p < 0.05) and highly significantly different between 2022 and 2023 and between 2023 and 2024 (p < 0.01), with no significant differences between 2020 and 2022 (p > 0.05). NO₂ levels were significantly different between 2020 and 2021 (p < 0.05) and between 2022 and 2023 (p < 0.05), while other comparisons showed no significant differences (p > 0.05). Aerosol levels were highly significantly different between 2021 and 2022 (p < 0.01), with no significant differences in the other periods (p > 0.05). Pollution hotspots were found around Onitsha Main Market, Niger Bridge, and Ochanja Market, linked to traffic, industries, and open waste burning. Despite fluctuations, pollutant levels were high, posing health risks. Addressing this requires stricter emission controls, better transportation policies, and continuous air quality monitoring.

Background The extracellular vesicle (EV) pathway plays a critical role in cell-to-cell communication. Cancer cells release EVs into the extracellular space, where they interact with both cancerous and noncancerous cells, activating signaling pathways and remodeling the tumor microenvironment (TME). In this study, we investigated the functional role of EVs released by FGFR2-amplified cancers of unknown primary (CUPs), which generate extrachromosomal circular DNA (ecDNA) to enhance oncogenic amplification.Methods FGFR2 copy number was quantified using droplet digital PCR (ddPCR) and visualized using fluorescent in situ hybridization (FISH). EVs were isolated via ultracentrifugation, and the circular nature of FGFR2 ecDNA was assessed using Plasmid-Safe ATP-dependent DNase treatment and atomic force microscopy (AFM). Oncogene transfer through EVs was evaluated by administering isolated CUP-derived EVs to recipient NCI-N87 cells or by using a coculture system that facilitated EV transfer to THP-1, HUVEC, and fibroblast cell lines.Results CUP-derived FGFR2-containing ecDNA, which is partially circular, was packaged within EVs and exhibited functional activity upon delivery to TME cells. When cancer (NCI-N87, THP-1) and noncancer (HUVECs, fibroblasts) cells were exposed to CUP-derived EVs—either via direct administration or coculture—they internalized FGFR2 DNA, which was subsequently transcribed, leading to altered cell morphology and increased proliferation, depending on ecDNA type. CUP-derived EVs induced THP-1 polarization toward the M2 macrophage subtype and promoted HUVEC proliferation.Conclusion This mechanism of oncogene transfer can contribute to TME remodeling, potentially explaining the early metastatic potential of CUP.

Published: February 2025

X-ray Computed Tomography (CT) is widely recognized and globally utilized due to its rapid imaging capability, high spatial resolution, and excellent density resolution. However, the large volume of CT examinations, coupled with complex and repetitive operation procedures, has increased the workload of radiographers and the risk of errors. This is particularly evident in populous countries such as China and India, especially during the prevalence of respiratory infectious diseases or in high-throughout scenarios such as large-scale lung cancer screening. There is an urgent need to enhance the intelligence level of CT examinations to reduce the workload while improving efficiency and quality.
To address this challenge, we propose a CT operation agent named Agentographer, which can autonomously perform CT examinations instead of human technicians. We curated a comprehensive multimodal dataset consisting of radiographer-patient interaction videos with associated Q&A transcripts from four distinct brands and models of CT scanners. After that, the dataset was used to train LLaMA-CT, a model specifically fine-tuned for dynamic scene perception and decision-making during CT examinations.
Then, powered by the LLaMA-CT, Agentographer integrates AI-driven patient interaction, 3D-camera-based isocenter positioning, segmentation-based CT scan location, automated device control, and AI-driven diagnostic and report models into a unified system. In a subsequent clinical trial of 500 subjects undergoing chest CT for lung cancer screening, Agentographer independently completed 476 cases (95.2%), achieving a significant reduction in both effective radiation dose (7%, P<0.001) and CT examination duration (9.3%, P<0.001), facilitating radiologists to issue diagnostic reports 12 hours earlier compared to a control cohort of 510 subjects examined by Radiographers.

Authors: Wagner Marlene , Gössl Alexandra , Pishtari Gerti , Ley Tobias
Published: February 2025

In diesem Beitrag wird untersucht, welche Potenziale Künstliche Intelligenz (KI) für das Lehren und Lernen an Hochschulen bietet und welche Lehr-Lern-Prozesse durch den Einsatz von KI-Systemen sinnvoll unterstützt werden können. Dazu wurden zahlreiche Strategiepapiere zu KI, welche in den letzten Jahren im deutschsprachigen Raum sowie von EU-Institutionen und internationalen Organisationen (z. B. UNESCO, OECD) publiziert wurden, gesammelt und analysiert. Um die Potenziale von KI systematisch zu erfassen und zu bewerten, wurde das Modell der fünf Systemebenen der Lernumwelt Hochschule (Makro-, Exo-, Meso-, Mikro- und Individualebene) herangezogen. Dieses Modell ermöglicht eine strukturierte Betrachtung der verschiedenen Einflussbereiche und Ebenen, auf denen KI in der Hochschullehre wirken kann. Ein besonderer Fokus wurde dabei auf die Mikroebene gelegt, die sich direkt mit den Lehr-Lern-Prozessen befasst. Abschließend werden konkrete Handlungsempfehlungen für Lehrende und Studierende präsentiert, darunter die gezielte Integration von KI-gestützten Tools wie ChatGPT in die Lehre, die Anpassung der Prüfungsformate und Bewertungskriterien, die Förderung von kritischem und strukturiertem Denken sowie die Einhaltung ethischer Richtlinien im Umgang mit KI.

Published: February 2025

Students struggle with coding in R, often resulting in low R-associated self-efficacy. Given the rise of AI, we examined in five seminars whether AI boosted self-efficacy of 57 students compared to a prior session. However, we found no significant increase in R-associated self-efficacy. Of 11 exploratory analyses we found in one analysis an unexpected result that we interpreted as disappointed expectations. This result underlines the importance to effectively handle students’ expectations and experiences when using AI.

Published: February 2025

Путем сопоставления отдельных диалогов трагедии Еврипида «Медея» в тексте обозначаются фрагменты, в которых зафиксированы представления драматурга о современной ему педагогической реальности. В «Медее» Еврипидом представлена иерархия добродетелей, которая должна быть принята тем, кто претендует на статус образованного человека. Изменяя мифологический сюжет и высвечивая изменения целым рядом новаторских художественных приемов, Еврипид демонстрирует процесс и результат перевоспитания Медеи-дочери, Медеи-жены и Медеи-матери, которая стремится образумить других и образумиться сама в условиях деления на «своих» и «чужих».

By comparison of separate dialogues in the Medea we isolate passages where Euripides inform us about contemporary educational reality. In his Medea, Euripides presents the hierarchy of virtues, which has to be accepted by any ‘educated’ person. Having changed the mythological plot and highlighted these changes by a number of innovative artistic touches, Euripides shows process and result of re-education of Medea-daughter, Medea-wife and Medea-mother who seeks to make understand others and bring herself to reason, being placed in the circumstances which force her to divide between the «one’s own» and the «others».

В сохранившихся манускриптах Первого послания Павла к Коринфянам слова Христа в стихе 11:24 встречаются в двух разных вариантах: в одном из них есть слова «приимите, ядите», а в другом их нет. Между этими двумя вариантами есть значительное смысловое различие. Расширенный вариант подчеркивает индивидуальный аспект Евхаристии, а краткий, напротив, институциональный. Существование этих двух вариантов может послужить важным свидетельством о динамике идейных трансформаций, происходивших в древней церкви. В зависимости от того, какой вариант считать исходным, а какой исправленным, история ранней церкви будет рассматриваться либо как процесс клерикализации, либо как индивидуализации.

Available manuscripts of Paul’s First Epistle to the Corinthians have a variant reading of Jesus’ words at the Last Supper in 11:24. The longer reading contains “take, eat” while the shorter reading does not. The two readings have a noticeable difference in meaning. The longer one highlights the individual value of the Eucharist; the shorter version, however, favors its institutional significance. The existence of both readings can be interpreted as a witness to an ideological dynamics in the early church. Depending on which of the two readings is considered prior, the church history would be seen either as an increase of clerical authority, or as an increase of value of the individual.
Meaning as convention: a puzzling effect of Aristotelian theory of names
Authors: Chernyak A.
Published: February 2025

According to Aristotle spoken words are signs of impressions, and those words which are used as names have conventional meanings. This theory of meaning poses a problem because it is unclear how exactly impressions which are essentially subjective may be assigned to names conventionally, i.e. due to certain interactions between different persons. In the following article the nature of the problem as well as the most prominent notions of conventions are analyzed: it is shown that considering the ways by which conventions about meanings should be established according to them the problem cannot be eliminated. It is also claimed that this is the problem not only for the particular Aristotle's theory of names, but also a problem for a much wider set of theories of meaning and interpretation
ВИТГЕНШТЕЙН И ПЛАТОН: ВОПРОС О ДИАЛОГЕ
Authors: РОДИН К.А.
Published: February 2025

Антиплатонизм Витгенштейна в этике, философии религии и в философии математики хорошо известен. Однако подход Витгенштейна к текстам Платона и способ обращения Витгенштейна с некоторыми идеями Платона часто не обращают на себя должного внимания. В статье анализируются встречающиеся в текстах Витгенштейна ключевые цитаты и ссылки на Платона. Подробно рассматриваются соответствующие контексты цитирования. Доказывается, что единственный прямой интерес Витгенштейна к Платону касается диалоговой формы диалогов Платона и что природа языка или знания - как близкая по тематике составляющая платоновского дискурса - как таковая не интересовала Витгенштейна.

Wittgenstein’s Anti-Platonism in a field of ethics, philosophy of religion and philosophy of mathematics is a common place in Wittgenstein studies. But Wittgenstein’s approach to Plato and especially the way Wittgenstein reads Plato’s dialogues are usually dismissed. In the article, I recollect nearly all passages in Wittgenstein’s texts where Wittgenstein gives any quotations from Plato or any comments on Plato and Socrates. I analyze contexts in which these quotations and comments emerge. Then I argue that the only theme Wittgenstein was interested in Plato’s dialogues was the dialogical form itself and that the nature of language or the nature of knowledge (as a part of Platonistic discourse) appears to be of no interest for Wittgenstein.
"ЛЕКАРСТВО ДЛЯ ПРИПОМИНАНИЯ". ПЕРИПАТЕТИЧЕСКОЕ КОНСТРУИРОВАНИЕ ИНТЕЛЛЕКТУАЛЬНОЙ ИСТОРИИ ГРЕЦИИ. ДИКЕАРХ И ФИЛОСОФСКАЯ БИОГРАФИЯ
Authors: АФОНАСИН Е.В.
Published: February 2025

Перипатетику Дикеарху принадлежала серия работ, посвященных интеллектуальной истории Греции, в том числе первый опыт того, что можно называть философской биографией. В качестве этапов развития философской мысли Дикеарх выделяет семерых мудрецов, Пифагора, Сократа и Платона, причем, каждый раз его интересует эволюция образа жизни философа от одиноких размышлений «мудрецов», через социальный морализм Пифагора и Сократа до «академической» жизни ученого. К сожалению, ни одно из сочинений Дикеарха не дошло до нас. Публикуемые свидетельства переводятся на основе нового издания фрагментов Дикеарха, сравнительно недавно опубликованного Mirhady (2001).

The Peripatetic Dicaearchus composed a series of works dedicated to the intellectual history of Greece. In a sense, he was the first ancient author to write a comprehensive history of philosophy, centered on such key figures, as the Seven Sages, Pythagoras, Socrates, and Plato. The sages are known for their highly practical maxims and general rules of right conduct; Pythagoras developed a new lifestyle and promulgated it in his public and private teaching; Socrates introduced a new form of intellectual and moral pursuit; while Plato founded an institutional framework for philosophical studies having thus paved the way to a systematic research, conducted by the Peripatetics. The evidences are translated on the basis of a new edition of Dicaearchus' fragments, prepared by Mirhady (2001).

O objetivo deste estudo é analisar, por meio de um framework teórico conceitual, a produção científica brasileira, disponível na base de dados Scielo.org, relacionada a agricultura familiar e desenvolvimento rural entre os anos de 2011 e 2020. Para a seleção e análise dos artigos foi utilizada a metodologia Methodi Ordinatio. A análise foi realizada considerando as seguintes variáveis: (a) o código do artigo; (b) periódico em que foi publicado; (c) ano de publicação; (d) título do artigo; (e) palavras-chave; (f) idioma; (g) autores; (h) estudos mais relevantes; (i) abordagem metodológica; (j) região onde o estudo foi desenvolvido; (k) linha de pesquisa. Os resultados mostraram que os periódicos nacionais que se destacam com maior número de publicações sobre o tema são a Revista de Economia e Sociologia Rural e a revista Interações. Percebeu-se que não existe uma tendência linear no número de publicações por ano e que a maioria dos artigos são estudos práticos, relacionados à linha de pesquisa Políticas Públicas e Governança.  Adicionalmente, constatou-se que a maioria dos artigos são estudos práticos, que se concentram principalmente nas regiões Sul e Sudeste do país. A principal contribuição do presente estudo é que ele estabelece as bases para estudos futuros sobre o tema e revela importantes lacunas da literatura.
LÓGICA NEBULOSA PARA O CONTROLE DE EXTRUSORAS DE PARAFUSO SIMPLES APLICADA AO PROCESSO DE FABRICAÇÃO DE PNEUS
Authors: Comenale Wagner , Wiltgen Filipe , De Almeida Luis Fernando
Published: February 2025

Este artigo apresenta a pesquisa referente ao desenvolvimento de um sistema de controle inteligente baseado na técnica de lógica nebulosa para utilização em uma extrusora de borracha na fabricação de pneus automotivos. O sistema de controle atua diretamente na pressão de saída do material extrudado de uma extrusora do tipo parafuso simples. O estudo foi realizado em ambiente industrial em uma extrusora de borracha com ~200mm de diâmetro utilizada na fabricação de pneus automotivos. A análise de diferentes variáveis do processo de extrusão permitiu estabelecer diferentes regras e funções de pertinência para o controle do sistema nebuloso. O sistema de controle nebuloso garante o fluxo constante do material extrudado através do controle da velocidade do parafuso da extrusora, garantindo desta forma, a estabilização do peso final do produto extrudado. Este comportamento estável garante não só níveis aceitáveis de peso do produto extrudado, mas também, reduz significativamente a perda de matéria-prima, assim como, as variações na qualidade no processo de fabricação de pneus na indústria automotiva.

Published: February 2025

Estudos de melhorias buscando cascos mais eficientes têm-se tornado acessíveis com o avanço de técnicas numéricas e recursos computacionais nas últimas décadas. Com objetivo da redução da resistência viscosa, o presente estudo utiliza uma abordagem numérica por meio do software livre OpenFOAM como estratégia na análise da eficiência do método de injeção de ar no fundo do casco Duisburg Test Case (DTC). O Casco apresenta uma geometria genérica de porta-contentores mais modernos, pertencendo a categoria de cascos de deslocamento, e é frequentemente utilizado na validação de estudos hidrodinâmicos. Especificamente, injetando ar na parte inferior do casco, essa técnica consiste em formar uma película de ar entre o casco e a água que contribui para a redução do arrasto viscoso, talmétodo é conhecido como ALDR sigla para Air Layer Drag Reduction. Parâmetros como:velocidade do casco, disposição dos bicos injetores, vazão de ar e ângulo de injeção sãodefinidos objetivando reduzir o arrasto viscoso. A simulação numérica conta com as metodologias: Volumes Finitos para discretização das equações de conservação; velocidadesmédias, RANS (Reynolds Average Navier-Stokes), na equação do movimento; k ?? - SST no modelo turbulento. Por fim, o método atingiu uma redução de 20,32% na resistência viscosa e 19,13% de redução na resistência total do casco DTC.

Published: February 2025

Uno de los legados más importantes que nos ha ido dejando el juego del Ajedrez a lo largo de la historia es su Patrimonio Bibliográfico. El juego o deporte sobre el que más páginas se ha escrito, algunas de una singular belleza y que en muchas ocasiones trascienden el ámbito ajedrecístico para poder considerarse un tesoro de la humanidad. Dentro de este inmenso patrimonio, los Manuscritos Medievales Europeos de Ajedrez, considerados estos los que dan alguna referencia al juego, suponen los cimientos de lo que luego ha resultado, con el paso de la historia, un edificio prácticamente inabarcable. Nos dejan grabado el comienzo y los primeros pasos del juego. Su devenir histórico, su relación con la sociedad y la de esta con el ajedrez, están plasmados en estos escritos, que sus autores dejaron para la posteridad. La aparición de las nuevas tecnologías ha propiciado la digitalización de los fondos bibliográficos en todo el mundo. Esta Investigación pretende la unificación en un catálogo digital, de los manuscritos de ajedrez medievales europeos, desde el que se pueda consultar los manuscritos digitalizados, estudios sobre la obra y toda clase de referencias. Completará el estudio una Base de datos de “juegos de partido” medievales, actualizando el estudio de Murray con las nuevas herramientas digitales. La investigación se encuentra en la Fase I (Localización y primera catalogación de documentos) y en el artículo se pretende dar a conocer los pasos realizados y las próximas acciones de investigación.

Published: February 2025

O presente artigo tem por objetivo apresentar um levantamento e análise das leis no âmbito nacional sobre o jogo de xadrez no Brasil. Este estudo, de abordagem qualitativa do tipo documental com dados de fontes primárias (MARCONI e LAKATOS, 2010), realizou a busca sistematizada das leis no site leismunicipais.com.br, a partir da palavra chave “xadrez” dentro das ementas. Foram encontradas 380 leis, sendo 357 de âmbito municipal e 27 de âmbito Estadual, datadas entre 1949 e 2021, presentes em 205 municípios, dentre esses, 14 capitais, em 20 Estados e em todas as regiões do país. A partir da análise documental (CELLARD, 2008) e da análise de conteúdo (BARDIN, 1979) as leis foram organizadas em três categorias e suas respectivas subcategorias: (a) Incentivo à modalidade esportiva do xadrez (229 documentos), (b) Incentivo ao ensino e aprendizagem de Xadrez em escolas (132 documentos), e (c) fomento à prática do jogo (19 documentos). O período pós Constituição Federal (1988) concentra a maior parte das leis, tendo seu ápice no período de 2002 a 2016, Nas regiões e Estados onde há mais leis, decretos e resoluções, há maior presença de jogadores cadastrados na Confederação Brasileira de Xadrez, suscitando uma possível correlação entre uma atividade mais constante do xadrez e a presença de leis de incentivo e fomento.
ON THE NEED TO INVESTIGATE CHESS ENGINES FOR EDUCATIONAL AND PSYCHOLOGICAL PURPOSES
Authors: Bart William M
Published: February 2025

The purpose of this study was to explore why and how chess researchers should investigate chess engines for educational and psychological purposes. The motivation for the study of chess engines for educational and psychological purposes is that such study will facilitate chess training and learning.A chess engine is software that can play chess. Examples of chess engines are Stockfish 14 and AlphaZero. Chess engines tend to be used for entertainment, recreation, and sport. But chess engines have the potential to be used for educational and psychological purposes in settings such as schools, colleges, universities, senior settings, and correctional facilities. However, certain issues regarding chess engines need to be investigated to allow chess engines to be more fully used for educational and psychological purposes. For example, there are chess engines that are assumed to be at certain levels of chess skill (i.e., Elo ratings), but the assumed Elo ratings for the chess engines have not been validated. Empirical research is needed to validate the assumed Elo ratings for various chess engines. Also, some chess engines are able to identify chess blunders. The blunders committed by chess engines and by human chess players should be analyzed and interpreted. Such blunder analysis can then inform efforts to improve chess teaching and practice for human chess players at various levels of chess skill.

Apresenta-se um estudo sobre as possibilidades de utilização do jogo de xadrez para o desenvolvimento cognitivo de crianças com transtorno do espectro autista - TEA. No decorrer do texto destaca-se a importância do uso de jogos nas escolas de ensino regular que atendem crianças com TEA, especialmente utilizando o jogo de xadrez para que possam desenvolver o seu raciocínio lógico e melhorar suas competências em relacionamentos sociais, fazendo com que realmente sejam incluídos na escola. Importante que as instituições de ensino tenham essa proposta do uso dos jogos independente das síndromes, transtornos ou deficiências, pois infelizmente ainda são pouco usados. A pesquisa apresenta abordagem qualitativa, por meio de um estudo de caso com uma criança de seis anos com TEA de grau médio, com registros em um diário de bordo. A coleta de dados da pesquisa foi complementada com a aplicação de questionário dirigido para um jovem adulto com TEA leve e com um professor de xadrez que trabalhou com jovens autistas. Com a intervenção realizada pode ser observada a melhora do desenvolvimento do aluno em questão, o qual é regularmente matriculado num Centro de Educação Infantil da rede pública Municipal da cidade de Joinville, SC.

Plantas são fontes de inúmeros compostos usualmente empregados para produção de medicamentos. Frações descartadas ou subutilizadas podem conter compostos bioativos que ainda podem ser extraídos, inclusive aplicando o ultrassom, gerando erupções que facilitam a extração dos compostos desejados. Objetivou elaborar revisão bibliográfica sobre métodos de extração de biomoléculas utilizando o ultrassom de sonda, comparando de forma sucinta ao banho ultrassônico. Três bancos de dados foram pesquisados (Google Acadêmico, Periódicos Capes e Research Gate), no período entre 2014-2021. Apurou-se 12 artigos, observando distinções entre tipo e proporção do solvente, matriz vegetal e rendimento do processo de extração. Comparando-se ao uso do banho ultrassônico, em geral, obteve-se maior rendimento utilizando o ultrassom de sonda. Para o ultrassom de sonda verificou-se o emprego de ampla faixa de frequência, potência e temperaturas de extração, ajustados de acordo com a matriz utilizada e a biomolécula alvo. Por fim, água e etanol foram os solventes mais empregados.
