Published: January 2025

The increasing development of car modification and the lack of understanding on the function of using spoilers or rear wings on vehicles, underlies the research on the aerodynamic forces acting on cars. The influence of this aerodynamic device will produce a compressive force to the bottom of the vehicle or called downforce, where this force is greatly influenced by the CL (lift coefficient) value. The purpose of this study was to determine the effect of variations in the tapper ratio on the value of downforce and drag force on on single-element type spoilers made using a NACA 6412 airfoil. The research was conducted using the Computational Fluid Dynamic method using ANSYS Fluent software with steady state pressure based solver. In this study five variations of the tapper ratio were used, namely: 1:1; 1:0.5; 1:0.7; 0.5:1; and 0.7:1. The fluid properties used are adjusted to the climate and weather in general air conditions and at air flow speeds of 100 km/h. Based on the research conducted, it can be concluded that the highest lift coefficient value was achieved in the 1:1 tapper ratio variation which was equal to CL = -0.2275 and CD = 0.0195. The highest downforce value is achieved in the 1:1 tapper ratio variation that is equal to L = -107,529 N and the largest drag force value is also achieved in the 1: 1 tapper ratio variation that is equal to D = 9.2269 N. The best CL/CD results are obtained at the 1:05 tapper ratio variation with a value of 12.82.

The study was conducted on GE 1.5 XLE wind turbine blades with a blade length of 4.32 m. This study uses a numerical simulation method with the help of ANSYS Workbench 19 software. Simulation is carried out at wind speeds of 3 m/s, 5 m/s, and 8 m/s. The DAWT (Difuser Augmented Wind Turbines) research model uses the same wind turbine blade as a conventional wind turbine model which is the same GE 1.5 XLE model. The size of the diffuser added to the construction of the wind turbine is 9 m in addition to flanged on the side of the inlet and outlet diffuser.Based on numerical simulations carried out, for wind speeds of 3 m/s, the highest increase in DAWT performance is 115.6%. For wind speeds of 5 m/s, the highest increase in DAWT performance is 99.2%. For wind speeds of 7 m/s, the highest increase in DAWT performance is 91.8%. Based on the simulation results it can be said that the addition of diffuser in the construction of wind turbines will produce effective performance at wind speeds of 3 m/s. The increase in DAWT performance is relatively small on TSR 1-4, and some even experience a decrease in performance. So that it can be said that DAWT is not suggested to be operated on a low TSR, DAWT is recommended to operate above TSR 5.

Published: January 2025

Heat treatable Al-Zn-Mg-Cu alloys are widely used in automobile industries, aerospace and military applications. This study investigates the effects of different amounts of copper and magnesium on microstructure and mechanical properties. The as-cast alloys prepared in a permanent mould showed a dendritic microstructure and the intermetallic phase surrounded by secondary phases. As-cast microstructure was refined substantially during hot rolling processes. The ultimate tensile strength and hardness values both in hot-rolled and aged conditions along longitudinal and transverse directions were found greater for the alloy containing 1.33 wt.% copper and 1.01 wt.% magnesium, whereas strain to fracture values for alloy 01 with 1.09 wt.% copper and 1.8 wt.% magnesium. The fracture surface of the tensile sample having relatively lower amount of copper content revealed dimple rupture behaviour, while higher 4.32 wt.% copper content indicated transgranular and cleavage fracture. A similar pattern was also observed along the transverse direction. Overall, copper appeared to be more effective in strengthening of the studied alloys.

Published: January 2025

The heat exchanger is an intermediary for two or more fluids that flow both inside and outside of the heat exchanger to distribute heat. This process was aimed to increase efficiency levels in the process industry. One of the suitable materials for the tube is UNS C44500, also known as admiralty brass consists of 70Cu-30Zn, which has high thermal conductivity and good corrosion resistance. However, admiralty brass was susceptible to stress corrosion cracking (SCC) when faced with nitrate since the tube was also loaded by internal stress. Moreover, SCC was also exacerbated by dezincification. The C-ring test method examined the effect of nitrate compounds and dezincification on SCC in C44500 Tube components.  Tensile stresses varied between 15, 45, and 85% of yield strength, which were immersed into nitrate solutions consisting of NaNO3 and Cu(NO3)2. Some specimens were washed using 20% ​​HCl to bring up dezincification. The results obtained that SCC occurred at the highest Cu(NO3)2 concentration, identified by longitudinal crack and passivity breakdown. All of the dezincified specimens were found cracked due to SCC after immersion into 1 M Cu (NO3)2, while un-dezincified were failed when given tensile stress between 45% to 85% of maximum yield strength.

Fish serves as the primary income source for the majority of fishermen in Indonesia. In order to preserve the freshness of the fish, fishermen commonly use styrofoam cool boxes. However, the use of styrofoam results in a significant quantity of waste that doesn't naturally break down. As a solution, a study was conducted to develop an alternative thermal insulation material for cool boxes. This material takes the form of a biocomposite, made from epoxy resin combined with water hyacinth and sugarcane bagasse fibers. The research’s results are A1 type had the lowest density value (0,795 g/cm3) and the lowest thermal conductivity value (0,1987 W/mK). The B3 type had the highest bending strength value (395,224 kg/cm2). All type of ratio variations’ density and bending strength test results are met the requirements of SNI 03-2105-2006. It can be concluded that A1 type is the best choice as a thermal insulation material purpose. After a cool box from composite (A1) manufactured, a comparison test between styrofoam cool box and composite cool box is being held. The 24-hour test result shows that styrofoam cool box still outperformed the composite cool box in terms of temperature maintenance.

The use of sand for metal molds is often found in various places; this research will focus on the type of sand used, namely sand from Lumajang Regency, which is known to be strong for concrete mixes or the like. So the purpose of this research is to find out how Lumajang sand molds will be used as metal casting molds. Testing will be carried out by making three variations of bentonite mixtures: 10%, 15%, and 20%. Later, after knowing the tensile and compressive strengths of each sand mold, casting will be carried out with three variations. For testing, casting objects will use the dye penetration test method. So that a description of the surface smoothness of the casting objects made from the three molds will be obtained and it will be known which variation is good to know about the sand mold and the appropriate metal casting results. From the results of the research conducted, it shows that the bentonite mixture with a percentage of 20% gets the highest compressive value with a value of 26.3 N/cm2 when compared to other bentonite mixture variations. From the tensile testing results, a high tensile strength value was obtained in the 15% bentonite mixture variation with a value of 0.7 N/cm2. While the results of the dye penetrant test were obtained, the results of the variation of the sand mold mixture with 20% bentonite into a mold produced the smoothest workpiece results with a few red spots caused during testing.

Authors: Irawan Yosua Heru , Nugraha Aditya Sukma , Lin Po Ting
Published: January 2025

This research focuses on optimizing the arrangement of Darrieus wind turbines through an adjustable R array, which represents the spacing between the turbine rotors. The ANSYS Fluent solver, employing the k-epsilon turbulent model and sliding mesh technique, is utilized to predict turbine performance. Additionally, a grid independence test is conducted to validate the solver's effectiveness. The optimization of the R array is achieved using the conjugate gradient method. Simulation results indicate that a blade grid size of 1 mm results in an error under 1%. A smaller R array yields a lower average coefficient of power (Cpaverage) due to the wake interactions between the rotors. The optimal spacing for each turbine to achieve a Cpaverage value of 0.4088 is determined to be 1.772 meters.
Al-Ṭayyibât and Al-Khâbisât in QS. al-Nur: 26: Comparative Insights from Ibn Jarir and Quraish Shihab
Authors: Djuned Muslim
Published: January 2025

The terms al-Ṭayyibât and al-Khâbisât in QS. al-Nur: 26 have long been central to discussions on Islamic marital ethics, particularly the principle of compatibility (kafa’ah) in moral and spiritual values. This study examines the interpretations of these terms by two prominent scholars: Ibn Jarir al-Thabari, representing classical exegesis, and Muhammad Quraish Shihab, offering a contemporary perspective. Using a comparative and descriptive-analytical approach, the research highlights key differences in their methodologies and contextual applications. Al-Thabari’s interpretation, rooted in asbab al-nuzul and linguistic precision, confines the meaning of al-Ṭayyibât and al-Khâbisât to speech, primarily defending the moral purity of Aisha RA against slander. In contrast, Quraish Shihab broadens the scope to include actions, behaviors, and character, emphasizing the principle of compatibility in relationships. This study finds that while Al-Thabari’s approach focuses on historical textuality, Shihab integrates socio-ethical considerations to address the practical challenges of modern marriage. The findings bridge classical scholarship and contemporary application, contributing to a nuanced understanding of QS. al-Nur: 26 and its relevance to marital ethics.

Published: January 2025

The river, a vital resource for agricultural, industrial, and domestic use, faces pollution pressures from anthropogenic activities. This study examines the water quality parameters of the Kemambang River in Sidoarjo, East Java, within the context of the One-Health Framework, emphasizing the interconnectedness of environmental, human, and animal health. Sampling conducted at three distinct points along the river revealed spatial variability in key parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), temperature, and oil and grease content. Analysis showed that while pH remained within acceptable limits, BOD and oil and grease levels exceeded regulatory standards, particularly downstream, where domestic and agricultural runoff contributed to oxygen depletion. Spearman correlation analysis highlighted strong positive correlations between TSS, COD, and oil and grease, while BOD and COD were negatively correlated with DO, underscoring the impact of pollutants on oxygen dynamics. These findings demonstrate how industrial and domestic activities compromise the river's ecological health, impacting human and aquatic systems. By adopting the One-Health Framework, this study provides a holistic perspective on water quality challenges, offering insights for targeted interventions and sustainable management practices.

Analisar a variabilidade da precipitação é essencial para o planejamento urbano e ambiental dos municípios e regiões do Brasil. Com isso, a pesquisa teve como objetivo avaliar a variabilidade da precipitação anual e da quadra chuvosa para o município de São Luís (MA). Foram utilizados os dados mensais de precipitação da série histórica de 1974 a 2022 obtidos no banco de dados do Instituto Nacional de Meteorologia (INMET). Assim, foi aplicado a técnica do Índice de Anomalia de Chuva (IAC) desenvolvida por Rooy (1965) e adaptada por Freitas (2004; 2005) para avaliar anomalias negativas e positivas de precipitação na região Nordeste do Brasil (NEB). O estudo demonstrou que a precipitação de São Luís tem baixa variabilidade na escala anual, contudo, ao analisar o IAC foi possível observar maior quantidade de anos com anomalias positivas. Assim, os anos de 1974 e 1985 foram classificados como anos extremamente chuvosos, enquanto a classe de extremamente seco foi verificada apenas em 1983. Além disso, na análise do período chuvoso março e abril se destacaram com as maiores quantidades de anomalias negativas, principalmente o mês de março. Entretanto, abril apresentou 8 anos com anomalias negativas nos últimos 10 anos, enquanto fevereiro e maio apresentaram equilíbrio entre as anomalias positivas e negativas durante toda a série histórica.
SUSTENTABILIDADE SOCIOAMBIENTAL COMO PROCESSO LUGARIZANTE EM ALVORADA (RS)
Authors: Da Silva Soares Karen , Marques Strohaecker Tânia
Published: January 2025

Resumo:
Os fluxos e usos que imprimimos na cidade transformam, ressignificam e possibilitam um novo olhar, ao longo do tempo, das rupturas e descontinuidades socioespaciais.  Esta pesquisa volta-se para a perspectiva da sustentabilidade socioambiental, selecionando como elemento de análise a economia municipal. Analisamos as marcas impressas pelos processos socioespaciais no sentimento de pertencimento dos cidadãos, na perspectiva do trabalho, consumo e permanência do capital no território, pensando que a população possa voltar-se para a cidade, como espaço de vivência, convivência e afetividade em razão dos efetivos e constantes usos e apropriações espaciais. Alvorada foi escolhida para este estudo por compor uma nova centralidade a partir de sua emancipação do município de Viamão, o maior da região metropolitana leste de Porto Alegre/RS. Na leitura desses processos socioespaciais que proporcionam ou não a sustentabilidade socioambiental e o sentimento de pertencimento, tecemos recortes espaciais, a partir de um estudo  com base no desenvolvimento dos setores da economia municipal, para compreender suas contribuições para que o capital permaneça no município, em termos de consumo,  empregabilidade e  consequente ou não pertencimento pela permanência dos cidadãos em Alvorada, o que consideramos como processos lugarizantes. Para isso, analisamos índices relacionados ao desenvolvimento humano e econômico do município, entrevistamos empreendedores locais e propusemos questionário, respondido por cidadãos alvoradenses. Os dados obtidos possibilitam algumas considerações que não se esgotam neste trabalho, mas que reforçam a necessidade premente da gestão pública municipal de Alvorada investir em políticas, planos, programas e ações que promovam uma relação de pertencimento da população ao território municipal e de sustentabilidade socioambiental local.

ANÁLISE DA “ESCREVIVÊNCIA” NA LITERATURA NEGRA FRONTEIRIÇA DE ALICE LIMA E BENEDITO C. G. LIMA
Authors: Ferreira Brizon Bezerra Caroline , Machado Garcia Arf Lucilene
Published: January 2025

Este trabalho propõe uma análise do conceito de negritude (CÉSAIRE, 2012) e de escrevivência nos poemas “Negra” (2020), de Alice Lima, e “Quem disse que sou negro?” (2005), de Benedito C.G. Lima, poetas negros corumbaenses. O estudo qualitativo e interdisciplinar propõe um foco na literatura a partir do seu viés social (CANDIDO, 2006), considerando autor, obra e aspecto social em que estão inseridos. A noção de identidade fluida também é utilizada no estudo, bem como a de Identidade Negra (MUNANGA, 1999). A análise apresentou a constatação de uma identidade negra por meio da escrita, a importância da literatura como forma de reconhecimento e afirmação de si e a retratação da fronteira Brasil-Bolívia como espaço em que se ressaltam os contrastes sociais e raciais.
ACOLHIMENTO DE ALUNOS PENDULARES EM PROJETOS ESPORTIVOS NA FRONTEIRA BRASIL-BOLÍVIA: BARREIRAS (IN)VISÍVEIS NOS DISCURSOS DOCENTES
Authors: Pacola Gilson , Henrique Golin Carlo
Published: January 2025

Unidades educacionais situadas em regiões fronteiriças usualmente lidam com situações peculiares. Em escolas localizadas na cidade brasileira de Corumbá, em Mato Grosso do Sul (MS), que faz fronteira com a Bolívia, analisou-se a percepção dos profissionais de Educação Física que atuaram em projetos esportivos em escolas públicas (estaduais e municipais), especificamente quanto à participação de discentes que moram na Bolívia e estudam no Brasil, intitulados academicamente como “alunos pendulares”. O estudo, de natureza qualitativa, adaptou a metodologia adotada por Moreira, Simões e Porto (2005). A pesquisa objetivou responder se existem “barreiras” para a participação de alunos pendulares nas práticas de Esporte Escolar (extracurricular) oferecidas como política pública gratuita no Brasil. Para definir a amostragem de docentes, utilizou-se o cruzamento de informações disponíveis em documentos públicos de ambas as redes de ensino. Selecionaram-se aqueles que integraram, no período de 2017 a 2022, o Programa MS Desporto Escolar (Prodesc), desenvolvido nas escolas da Rede Estadual de Ensino (REE) de MS e o Projeto de Iniciação e Treinamento Esportivo das escolas da Rede Municipal de Ensino (Reme), todas em Corumbá-MS. Os resultados indicaram que os maiores obstáculos dos alunos pendulares são a falta de transporte escolar e a deficiência da formação acadêmica complementar e continuada dos professores, além da dificuldade de comunicação entre os docentes brasileiros e os alunos oriundos da Bolívia.

O Instituto Moinho Cultural Sul-Americano é uma iniciativa social que atende crianças e jovens da região fronteiriça, envolvendo quatro municípios entre a Bolívia e o Brasil com a oferta de atividades de formação artística, complementada com a prática nas línguas de comunicação da região: o português e o espanhol. Este artigo trata sobre a implementação dos princípios da translinguagem nas práticas linguísticas realizadas nesse ambiente de educação não escolar, mediante um projeto de extensão aprovado pela Universidade Federal de Mato Grosso do Sul e conta com o apoio de pesquisadores da Universidade Estadual de MS, especialistas na área. A pesquisa qualitativa, de cunho etnográfico, objetiva desenvolver e registrar as atividades realizadas no transcorrer do projeto de extensão para sua posterior análise e reflexão. A ação prevê a participação de acadêmicos do curso de Letras do Campus do Pantanal da UFMS, na função de colaboradores auxiliares. O projeto em andamento tem propiciado a sensibilidade e reflexão dos participantes quanto ao repertório linguístico próprio e dos seus companheiros, com atitudes de reconhecimento da diversidade em um exercício que busca promover a justiça social.
How to Make Someone Important
Authors: Jewellery witch Seraphita
Published: January 2025

How to Make Someone Important is a performative video piece centred around the Importance Booster Medal, created for the Tactilite exhibition at Hobusepea Gallery in 2021.

The work delves into pseudomagic through symbolic rituals and sensory interactions. Seraphita intentionally trivialises the act of recognition: a person’s sense of importance is heightened when presented with a medal of merit.

Employing Haptic Visuality, this multisensory approach weaves together emotional resonance and speculative ritual, reimagining connection within a pseudomagical framework.

Over the past two decades, numerous studies have emphasised the
importance of including organic matter (OM) in land surface models
(LSMs) to accurately represent soil thermal and hydrological properties.
This is particularly relevant in Arctic regions, where organic-rich
soils are widespread. Consequently, most LSMs incorporate
parameterisations that account for OM effects, although these
implementations are often simplified. Recent advancements in global soil
datasets now enable more precise modelling of soil properties by
providing detailed inputs for soil composition and physical
characteristics. This study enhances the ORCHIDEE LSM by refining the
representation of soil organic and mineral content, as well as improving
parameterisations of heat capacity, thermal conductivity, and porosity,
using data from the SoilGrids 250m v2.0 database. The updated model is
evaluated across multiple Arctic sites and compared against two earlier
versions: (1) a Bulk version that neglects OM effects and (2) a
simplified version with a basic OM prescription. Results show that
incorporating OM into thermal process modelling significantly improves
soil temperature simulations, particularly at greater depths. For some
sites, root mean square errors (RMSE) are reduced by up to 25% compared
to the Bulk version, especially during the snow-free summer months.
These findings highlight the value of high-resolution soil datasets,
such as SoilGrids, for improving simulations of thermal dynamics in
carbon-rich Arctic soils.

Coralliform kidney stones represent a severe form of nephrolithiasis, posing significant challenges due to their size and associated complications, such as recurrent infections and renal impairment. We present the case of a 34-year-old female with chronic venous disease, anemia, and recurrent Escherichia coli urinary tract infections, who was diagnosed with a right-sided coralliform renal calculus and a ureteral pelvic stone. The management included semi-rigid ureteroscopy with laser lithotripsy for the ureteral stone, percutaneous nephrolithotomy (PCNL) for the coralliform stone, and placement of a ureteral stent. Despite anatomical challenges during PCNL, residual stones were addressed via staged extracorporeal shock wave lithotripsy. This case highlights the complexity of surgical management in advanced nephrolithiasis and the necessity for a multidisciplinary approach.

U radu se promatra i analizira uloga, mobilnost i umreženost mletačkih rektora u istarskim gradovima i posjedima tijekom druge polovine 15. i početkom16. stoljeća. Na temelju duždevih naputaka rad donosi pregled ovlasti, dužnosti i naknada rektora istarskih gradskih općina. Na temelju baza podataka The Rulers of Venice i TOPOS promatra se na kojim su pozicijama bili podestati pojedinih istarskih gradova prije i poslije stupanja u službu. U radu se promatra jesu li se oni uglavnom izmjenjivali na pozicijama u istarskim gradovima ili su imali i druge službe unutar mletačkog posjeda Stato da mar ili na kopnenom posjedu (Terraferma). Analizira se je li postojala kakva pravilnost i shema u dodjeljivanju podestatskih službi za istarske gradove, na koje su pozicije nakon istarskih oni odlazili, jesu li i članovi njihovih obitelji u pojedinim gradovima također bili na pojedinim pozicijama, te zašto su se u nekim mjestima službe podestata često odbijale.
