Fused Deposition Modeling (FDM) has become one of the most prevalent technologies in the field of additive manufacturing (AM). Nonetheless, polyethylene terephthalate glycol (PETG), a polymer renowned for its mechanical strength, has been significantly employed in 3D printing as an alternative to traditional materials. The incorporation of fibers renders PETG-based composites viable for a diverse range of applications. However, the tensile strength of PETG carbon fibre developed using FDM depends on multiple printing conditions. Therefore, this work aims to examine the impact of printing parameters (layer thickness, infill density, and printing speed) at three individual levels on the tensile and structural characteristics of PETG carbon fibre. A total of nine print runs were executed by manipulating the three parameters. Three samples were produced for each run to ensure consistency in the results. Tensile tests on the samples were carried out, and a scanning electron microscope (SEM) was used to examine the structure of the printed parts. Finally, L9 (33) orthogonal arrays were developed for the experiment. Following that, an analysis of variance (ANOVA) was conducted to determine the crucial factors and their ideal levels. The results showed that the infill density parameter significantly influenced the optimization of the tensile strength of PETG carbon fibre. The optimal value for this parameter was found to be 80%. Increasing the density of the infill improves the tensile strength by reducing the air gaps and decreasing deformation, leading to a solid and tightly packed structure. Thereafter, the most effective settings were identified as a layer thickness of 0.4 mm, an infill density of 80%, and a printing speed of 30 mm/s.

In many scenarios involving mechanical contacts loaded in the elastic-plastic domain, finding the pressure distribution and the related stresses without a detailed description of the plastic strains may be a sufficiently good approximation for the contact problem solution. This approach is considered in this work, which aims to achieve a rapid solution for the pressure distribution in elastic-plastic contacts without the solution of the residual part: the influence of the plastic strains on the contact geometry, i.e., the residual displacements, and on the subsurface stresses, i.e., the residual stresses, are not accounted for. Experimental works and numerical approaches from the literature prove that the pressure in elastic-plastic contacts is limited to roughly three times the yield strength of the softer material. The latter threshold is introduced in a previously developed computer code for the purely elastic contact, as an additional restriction. The elastic-plastic pressure is calculated from the solution of the purely elastic problem, but it is not allowed to exceed the aforementioned limit. Considering the iterative nature of the original elastic solver, algorithm convergence is not affected by the additional restriction. The technique is firstly applied to a Hertz-type contact to prove the solution viability. A roughness sample is then processed with the newly advanced computer program. The resulting pressure distribution is compared to the purely elastic case. Considering that the former was achieved with the same computational effort as the latter, it is clearly a more convenient solution for practical engineering purposes.

Porous Nanomaterials for Iodine Adsorption
Authors: Wu Yichao
Published: January 2025

As global environmental issues become increasingly severe, the overconsumption of traditional energy sources and the associated pollution problems have become more prominent, creating an urgent need to find cleaner and more efficient alternative energy sources. In this context, nuclear energy, as a low-carbon and high-efficiency energy option, has gradually gained widespread attention. With the continuous development of nuclear technology, the application of nuclear energy has expanded globally. However, the widespread use of nuclear energy has also brought about various environmental challenges, particularly in terms of nuclear waste disposal, radiation safety, and the risk of nuclear accidents, which have sparked extensive discussions on the sustainability of nuclear energy. Of particular concern is the radioactive iodine released during uranium fission reactions, which poses significant potential risks to human health and the ecological environment, making the removal and enrichment of iodine an urgent issue. To address this challenge, porous nanomaterials, with their excellent adsorption properties and high surface area, have become a research hotspot in recent years and shown great potential for iodine removal and enrichment. This review focuses on the application of porous nanomaterials in iodine adsorption, including metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and porous organic polymers (POPs), and discusses the synthesis methods of these materials as well as their practical applications in iodine removal. Finally, the future development trends of porous nanomaterials in iodine adsorption are also envisioned.

In this paper, we first concern the existence of solutions of the complex $m$-Hessian type equation $-\chi(u)H_{m}(u)=\mu$ where $\mu$ vanishes on all of $m$-polar sets in the class $\mathcal{E}_{m,\chi}(\Omega)$. Next, we study the existence of solutions of this equation in the class $\mathcal{E}_{m,\chi}(\Omega)$ if there exists subsolution in this class. Using the above results, we study subextension in the class $\mathcal{E}_{m,\chi}(\Omega)$.

Completely bounded approximation property of semigroup crossed products
Authors: Meng Qing
Published: January 2025

In this paper, we study the CBAP of the reduced semigroup crossed product $\mathcal{A}\rtimes_{\alpha,r}P$ for a quasi-lattice ordered group $(G,P)$. We prove that if $G$ is amenable and $\mathcal{A}$ has the CBAP, then $\mathcal{A}\rtimes_{\alpha,r}P$ has the CBAP with the same Haagerup constant. We relate the CBAP of $\mathcal{A}\rtimes_{\alpha,r}P$ with an approximation property for completely bounded kernels over $P$. When $P$ is right Ore, we introduce and characterise the weak amenability of $P$ as the CBAP of the reduced semigroup $C^*$-algebra with respect to the canonical tracial state and the linear space of finitely supported functions on $P\times P$.

On some zero-sum invariants for abelian groups of rank three
Authors: Zhang Shiwen
Published: January 2025

Let $G$ be an additive finite abelian group with exponent $\exp(G)$. For $L\subseteq\mathbb N$, let $\mathsf{s}_{L}(G)$ be the smallest integer $\ell$ such that every sequence $S$ over $G$ of length $\ell$ has a zero-sum subsequence $T$ of length $|T|\in L$. In this paper, we consider the invariants $\mathsf{s}_{[1,t]}(G)$ and $\mathsf{s}_{\{k\exp(G)\}}(G)$ (with $k\in\mathbb N$). We obtain precise values as well as upper bounds of the above invariants for some abelian groups of rank three. Some of these results improve previous results of Gao--Thangadurai and Han--Zhang.

Encryption of Biometric Traits to Avoid Privacy Attacks
Authors:   Dept of CSE  Presidency University  Bangalore, India, Karthik Tripurari Vinay
Published: January 2025

In the modern digital world, biometric systems are a significant part of personal identification and access control. The use of sensitive biometric data such as iris and facial features raises huge privacy concerns because of the possibilities of data breaches and misuse. Therefore, this project focuses on the enhancement of the security of multimodal biometric systems through encryption mechanisms. The idea is to generate a strong biometric key based on features produced from iris and face biometric systems through advanced machine learning techniques. The features are then employed to produce a strong biometric key capable of encrypting the secret value using the AES algorithm. AES is a widely adopted symmetric encryption algorithm that ensures high efficiency in its software implementation and seamless processing capabilities of image data. This provides not only the reinforcement of authentication but also maintains confidentiality of biometric characteristics and mitigates the risks of privacy attacks and unauthorized access. Thus, this multimodal biometric encryption improves reliability, robustness, and the resistance power of the system against potential attacks, making it a promising step forward in the realm of secure biometric authenticationsystems.

MOLECULES OF CONSCIOUSNESS: THE ROLE OF NEUROTRANSMITTERS IN PSYCHIATRY AND SPIRITUAL EXPERIENCES
Authors: Yeghiyan M.G. , Palyan D.A.
Published: January 2025

The human brain is a unique and complex system where neurotransmitters are not merely biological components but may serve as "divine tools" enabling higher states of consciousness. Endogenous DMT (dimethyltryptamine) emerges as a key substance capable of inducing altered states of awareness linked to profound spiritual and mystical experiences. Research suggests that DMT, produced naturally in the brain, may become active during critical life situations, facilitating a transformation in perception. Recent studies also restore the scientific significance of psychedelics, highlighting their role in psychiatry, particularly in the treatment of depression, PTSD, and addictions. This article explores how neurotransmitters and DMT can be viewed as bridges connecting the biological and spiritual dimensions of human existence.

Authors: Nurriza Sofiastuti  , Sulistyowati Sulistyowati
Published: January 2025

Telemarketing is a modern marketing strategy that relies on long-distance communication to offer products or services. This strategy offers several advantages, including cost efficiency, two-way communication, and the ability to reach consumers personally. However, telemarketing also poses ethical challenges such as privacy violations, misuse of data, and the risk of manipulation in communication. From an Islamic perspective, Shariah-compliant telemarketing should prioritize the values of honesty (ṣidq), transparency (bayān), and non-coercion (ikhtiyar). The purpose of this study is to examine how telemarketing can be ethically applied in accordance with Islamic principles to create transactions that are fair, efficient, and spiritually and socially beneficial. This study was conducted through literature analysis related to marketing strategies, Islamic business ethics, and telemarketing practices. The results show that the implementation of Islamic telemarketing has the potential not only to increase marketing effectiveness, but also to become a means of da'wah in promoting Shari'ah values. This conclusion reinforces the importance of integrating ethical values into any business strategy to ensure the achievement of maslahat for all parties involved.

Published: January 2025

Amb abundants fonts dels Archives Nationales de París, aquest text tracta, a partir del cas del Faisceau, la relació de l'emergència del feixisme francès i del veterà de guerra com un subjecte polític tenint en compte tres eixos. Primerament, que el projecte feixista forma part d'un espai contrarevolucionari que, des de la victòria del Cartel, va intentar organitzar políticament els excombatents. Segonament, quin va ser el suport dels veterans de guerra en la construcció del partit feixista. Per últim, la quin pes van tenir els excombatents com a militància en la presa de decisions de la directiva. Aquests tres aspectes porten a replantejar la narrativa de la "brutalització" com a clau explicativa de l'ascens al feixisme.

Authors:   Specialist in education and food, Doctoral student in Community Intervention and Action University of Yaoundé 1 (Cameroon), Charline TIAKOUANG Zosie
Published: January 2025

Food security refers to the availability of sufficient, accessible, stable and wisely used food. Thus, food supply is a determinant of food security and food insecurity in turn. Given the statistics on food insecurity in sub-Saharan Africa, and in Cameroon in particular, and the impact of food on school performance, this article takes stock of the food supply in the Yaoundé I university environment. An observation guide is used to identify the various foods on offer. It shows that there are two main types of catering, morning and midday. These restaurants offer a variety of foods, including cereals, starchy foods, fruit and vegetables, pulses and various drinks. Apart from these two types, other foods are available at any time of day, such as snack products (caramel, salted peanuts, etc.). However, future studies will have to assess the nutritional and health quality of these foods and also evaluate other pillars of food safety, namely access, stability and use of these foods, in order to assess the general state of food safety in this educational environment.

From Fun to Fear: Unpacking the Emotional Triggers of Cross-Border E-Commerce Repurchases
Authors:   Department of Accounting and Information Management, Da-Yeh University, Taiwan, Yang Feng-Chao
Published: January 2025

This study explores how emotional triggers—specifically the interplay between perceived fun and fear—affect repurchase intentions on cross-border e-commerce platforms through the Unified Theory of Acceptance and Use of Technology (UTAUT) model. Additional variables, including online shopping fun and online shopping risk, are incorporated to provide a comprehensive analysis.

Data were collected through an online questionnaire survey, resulting in 270 valid responses. The study employed SmartPLS 4.0 to analyze the data, utilizing descriptive statistics, reliability analysis, validity tests, and structural equation modeling (SEM) to evaluate the research hypotheses.

Effort expectancy, facilitating conditions, and online shopping fun positively influence repurchase intention and behavior. However, performance expectancy and social influence do not significantly impact repurchase intention. Online shopping risk has a negative effect on repurchase intention, indicating that consumers’ concerns about security and privacy reduce their likelihood of repurchasing.

Cross-border e-commerce platforms should prioritize improving usability and providing support features to enhance customer experiences. Incorporating engaging features and mitigating perceived risks can significantly encourage repeat purchases. These insights are critical for platform developers and marketers aiming to foster customer loyalty.

This study extends the UTAUT framework by incorporating shopping fun and risk as contextual variables, providing novel insights into consumer behavior on cross-border e-commerce platforms. The findings offer practical recommendations for enhancing user experience and addressing specific challenges in the e-commerce domain.

Isso poderá apresentar oportunidades de melhoria para setor, bem como balizar a elaboração de políticas públicas mais específicas e eficientes para a agroindustrialização da uva. Este trabalho apresenta um diagnóstico do processamento de uva no Espírito Santo. A metodologia consistiu na pesquisa de campo em agroindústrias no estado. A estimativa de processamento da uva no Estado, considerando todo o universo de agroindústrias, representou 26,16% da produção. As formas de utilização da uva nas agroindústrias do Estado são para a produção de vinhos, polpas para sucos, sucos prontos, espumantes e geleias, sendo o vinho o principal produto. Dentre as principais dificuldades enfrentadas pelas agroindústrias está a sazonalidade da matéria-prima, a adequação das instalações, assim como o capital de giro insuficiente. A comercialização dos produtos das agroindústrias para outros estados, especialmente Minas Gerais e Rio de Janeiro, é realizada por 35,7 % das agroindústrias. A pesquisa mostra que existe uma oportunidade de expansão da produção e processamento da uva no Espírito Santo, bem como expansão da comercialização para outras localidades.

A sexagem fetal é o método de avaliação do sexo do feto durante a gestação, podendo ser avaliada por diversas técnicas diferentes, sendo de fácil execução, e auxiliando no manejo reprodutivo da propriedade. São diversas as técnicas descritas na literatura para a determinação da sexagem fetal, dentre elas a que foi utilizada neste trabalho, feita através das gônadas fetais. Este método é realizado em conjunto com a identificação da genitália externa (prepúcio ou clítoris), a qual tem origem no tubérculo genital. A janela de avaliação indicada é de 110 a 140 dias de gestação e a eficácia da técnica varia de 84% a 100%. O O objetivo do presente trabalho foi descrever a biotécnica, abordando a anatomofisiologia da sexagem fetal através da ultrassonografia e expor os resultados encontrados a partir da avaliação de 24 éguas seguindo a metodologia das gônadas, através da utilização do ultrassom transretal, diferenciando as características entre os gêneros e avaliando a acurácia do método escolhido através do experimento. Para o desenvolvimento do trabalho foram avaliadas 24 éguas prenhes da raça Mangalarga Marchador, entre as idades de 4 até 18 anos, pertencentes às propriedades denominadas 1, 2 e 3, localizadas na cidade de Taubaté/SP, sendo 1 e 2 avaliadas em 2023 e a propriedade 3 em 2024. Utilizou-se um aparelho de ultrassonografia da marca Ultramedic®, modelo Infinity i3V, com um transdutor linear transretal e com frequência de 5Mhz para realização das análises. Pode-se compreender que a realização da sexagem fetal em equinos é de extrema relevância, uma vez que, de acordo com a raça e o sexo do futuro potro, o manejo e as tomadas de decisões, relacionadas a questões comerciais, podem ser planejadas de formas mais eficientes. A partir da pesquisa foi possível observar um resultado de 100% de acurácia da técnica de sexagem fetal pela gônada através da ultrassonografia entre a janela de 110 a 140 dias de gestação.
“Na minha casa não tem porta e nem janela”: a repressão policial às religiosidades afro brasileiras na Bahia da Primeira República ao Estado Novo
Authors: Ferreira Beatriz Heloiza
Published: January 2025

O presente trabalho objetiva analisar o contexto histórico e político da repressão policial às religiosidades afro-brasileiras na Bahia dos anos iniciais do republicanismo ao Estado Novo. Sustenta-se o posicionamento de que embora as Constituições ampliassem a liberdade religiosa a partir da Primeira República, em paralelo há um movimento de institucionalização da perseguição penal dessas religiosidades por meio da criminalização das práticas de curas populares e do baixo-espiritismo no Código Penal. Inicialmente, há a apresentação do que as Constituições determinam sobre liberdade religiosa. Logo em seguida, apresentam-se os dois projetos políticos nacionais: a Primeira República e o Estado Varguista, relacionando os institutos penalizantes às demandas políticas vigentes neste período. Posteriormente, discute-se a questão racial da criminalização do espiritismo e do curandeirismo e os respectivos problemas de ordem jurídica existentes na tipificação dessas práticas. Por fim, apresentam-se alguns processos penais que marcaram o tema. Conclui-se que para levar a sério o instituto da liberdade religiosa no Brasil é adequado abordar as razões históricas que mitigaram a adesão social deste direito constitucional.

The Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, Asexual, and Pansexual (LGBTQIAPN+) population is often neglected when it comes to the realization of their rights, including access to public health services, where they frequently face unpreparedness and lack of sensitivity among healthcare professionals. Increasingly, one hears, through mass media, statements by political figures that involve matters of sexuality policy, jurisdiction over bodies, sexual practices, and control over affective-sexual experiences. The National Policy for Comprehensive LGBT Health is an initiative aimed at promoting greater equity within the Unified Health System. The Ministry of Health's commitment to reducing inequalities began in 2008, forming one of the strong foundations of the "More Health - Right for All" Program. Ensuring citizenship and dignity is the fundamental basis for every individual in a democratic country. Each human being is unique, but we still live in a diverse society, and as such, each person constructs their own story. This study's main objective is to evaluate the perception of LGBTQIAPN+ users regarding the care provided by healthcare professionals in Primary Care Basic Health Units. An exploratory qualitative study was conducted, using a questionnaire administered via Google Forms, with 48 participants from an LGBTQIA+ academic league at a community university. Of these, 33 met the inclusion and exclusion criteria and remained in the study, with the predominant age group being 18 to 22 years old. All ethical aspects were respected in accordance with National Health Council Resolutions No. 466/2012 and No. 510/2016 regarding research involving human subjects. The interviewees are referred to as "E" followed by their respective number in order to maintain confidentiality. The analysis and discussion of the results were organized following the proposed content analysis.

Introdução: As doenças neurodegenerativas, como a doença de Parkinson e a doença de Alzheimer, representam um grande desafio de saúde público a nível mundial, haja vista sua crescente incidência devido ao envelhecimento populacional, o que se traduz na necessidade de se buscar meios de melhorar a condução e o tratamento dos casos. Objetivo: O presente estudo teve como objetivo avaliar a eficácia da suplementação de creatina sobre a função cognitiva em pacientes com a doença de Parkinson e a doença de Alzheimer. Materiais e Métodos: Trata-se de uma revisão integrativa de literatura sobre a eficácia da suplementação de creatina sobre a função cognitiva de pacientes com a doença de Parkinson e a doença de Alzheimer. Utilizou-se a estratégia PICO para a elaboração da pergunta norteadora. Ademais, realizou-se o cruzamento dos descritores “Doença de Parkinson”; “Creatina”; “Doença de Alzheimer”, nas bases de dados National Library of Medicine (PubMed MEDLINE), Scientific Eletronic Library Online (SCIELO), Ebscohost, Google Scholar e Biblioteca Virtual de Saúde (BVS). Resultados e Discussão: Os estudos demonstraram as principais características clínicas e fisiopatológicas das duas doenças, bem como os mecanismos celulares que resultam na patologia. Além disso, descreveram possíveis formas de atuação da creatina sobre as doenças. Conclusão: Embora existam evidências in vitro e in vivo dos benefícios da suplementação de creatina sobre a neuroproteção em pacientes com a doença de Parkinson ou com a doença de Alzheimer, ainda não foram comprovados cientificamente em humanos, o que resulta na não recomendação sistemática da suplementação nesses casos.

A hérnia inguinal é uma das patologias mais prevalentes no campo da cirurgia, com alto índice de recorrência após o tratamento. Este estudo tem como objetivo analisar as taxas de recorrência das hérnias inguinais associadas a diferentes técnicas cirúrgicas, como a abordagem aberta de Lichtenstein, a laparoscópica e a Técnica Endoscópica Total (TEP). As taxas de recidiva são influenciadas por vários fatores, como a experiência do cirurgião, as características do paciente e a técnica utilizada. A técnica de Lichtenstein, embora eficaz, apresenta uma taxa de recorrência de 1 a 3%, principalmente em casos de obesidade ou complicações pós-operatórias. A laparoscopia, por sua vez, apresenta menor taxa de recorrência, mas o risco de complicações como lesões acidentais pode afetar os resultados. A TEP, ao ser indicada para pacientes com hérnias recidivantes, também apresenta boas taxas de sucesso, embora sua eficácia dependa da experiência do cirurgião. O estudo conclui que, apesar das melhorias nas técnicas de correção, a recorrência de hérnias inguinais ainda é um desafio, exigindo um acompanhamento rigoroso e a escolha personalizada da técnica cirúrgica.
