Abstract: This study has examined the design proposal for a support structure for a rainwater storage tank, utilizing CAD/CAE software with computational numerical analysis. These tools predict how elements will behave under specific conditions without physical construction. The necessity arises from the importance of developing the entire rainwater harvesting system to offer a sustainable water supply alternative. To this end, a storage capacity of 500 liters was determined based on locally available plastic tanks, considering the dimensions and weight the structure needs to support. 3D modeling utilized a 50 mm (2 in) square steel pipe discretized through meshing. Validation of this process achieved a skewness of 0.2401 with 414 651 elements and 601 334 nodes, defining the corresponding initial and boundary conditions. Von Mises stress measured 189.5 MPa, below the yield limit for structural steel, with structural element deformation not exceeding 0.83 mm. Design validation was accomplished through safety factor analysis, yielding a value of 1.746, closely aligning with recommended values for support structures.

Resumen: Esta investigación ha evaluado la viabilidad de un diseño para una estructura de soporte destinada a un tanque de almacenamiento de agua pluvial. Se utilizó software CAD/CAE para llevar a cabo un análisis numérico computacional debido a que estas herramientas permiten predecir comportamientos de elementos sometidos a condiciones específicas, sin necesidad de construcción. La necesidad de este diseño surge de la importancia de desarrollar un sistema integral para la captación de agua de lluvia, como una alternativa sostenible para el suministro de agua. Se estableció una capacidad de almacenamiento de 500 litros, considerando los tanques plásticos disponibles en el mercado local, para determinar las dimensiones y la carga que la estructura debe soportar. El modelado tridimensional se realizó utilizando una tubería cuadrada de acero estructural de 50 mm (2 plg), la cual fue discretizada mediante un mallado. Este proceso se validó alcanzando skewness de 0.2401, con un total de 414 651 elementos y 601 334 nodos, y se definieron las condiciones iniciales y de contorno correspondientes. El esfuerzo de Von Mises obtenido fue de 189.5 MPa, lo cual está por debajo del límite de fluencia para el acero estructural. Además, la deformación en los elementos estructurales no superó los 0.83 mm. El diseño se validó mediante un análisis del factor de seguridad, el cual fue de 1.746, aproximándose al valor recomendado para estructuras de soporte.

Abstract This paper analyzes the translation and validation of the instrument developed by Flores and Adlaon (2022) to apply the inductive method with the SAMR model in Spanish-speaking educational contexts. The justification for the topic lies in the need to adapt effective pedagogical tools to the Spanish language to facilitate their use in teaching and learning with technology. The main objectives were to translate the instrument and, through the judgment of experts in the educational and technological fields, to carry out its semantic validation. The methodology included the translation of the instrument “Extent of ICT Integration in Science Based on SAMR Model” into Spanish, followed by its validation. The 11 experts evaluated the relevance and clarity of the items using a Likert scale from 0 to 5. The content validity was calculated with the Aiken V methodology, obtaining a coefficient of 0.8163, which indicates a good validity index, the Cronbach’s Alpha value was 0.9682. The results showed that, although most of the items were well rated, some required reformulation to improve their clarity, relevance and comprehension in the Spanish translation. The instrument proved to be adequate for evaluating the degree of integration of ICT in education, facilitating its application in Spanish-speaking contexts and promoting the adoption of inductive methodologies supported by educational technologies.

BACKGROUND: Many serious adverse events associated with gestational diabetes mellitus (GDM) can be mitigated by timely glucose control during pregnancy, achieved through education and lifestyle choices. The aim of this study was to translate and cross-culturally adapt and test the preliminary internal consistency and test-retest reliability of the South African English, Afrikaans and isiXhosa versions of the GDM Knowledge Questionnaire (GDMKQ). METHODS: A prospective, observational study was conducted at a high-risk antenatal clinic in South Africa. Pregnant women ≥ 18 years with GDM were consecutively sampled. Semantic equivalence between the original and adapted versions was assessed. Face and content validity, internal consistency and test-retest reliability were evaluated. RESULTS: The three SA-GDMKQ versions demonstrated good face and content validity. For internal consistency, Cronbach's alpha values were 0.534 for the Afrikaans version, 0.434 for the English version and 0.621 for the isiXhosa version. Test-retest reliability found kappa (standard error [s.e.]) values ranged between −0.03 (0.18) and 0.89 (0.13) for the English version, between −0.07 (0.18) and 0.53 (0.13) for the Afrikaans version and between 0.28 (0.18) and 0.87 (0.17) for the isiXhosa version. All versions of the SA-GDMKQ had a statistically significant (p < 0.001) positive linear correlation between the total scores. CONCLUSION: The English, Afrikaans and isiXhosa SA-GDMKQ versions were found to be feasible and easy to comprehend, although lower internal consistency and test-retest reliability were displayed. Further validation of the psychometric properties of the English, Afrikaans and isiXhosa versions of the SA-GDMKQ among larger sample groups is however warranted. CONTRIBUTION: This study adds to the knowledge around developing and using culturally appropriate questionnaires and outcome measures in research and clinical practice.

Abstract Sapote gum (SG) is a new biopolymer with promissory functional properties. This study aimed to determine if SG is a suitable emulsifier for obtaining stable grape seed oil (GSO) emulsions. In the first stage, coarse emulsion concentrations of SG and grapeseed oil - GSO were evaluated, applying the Central Composite Rotational Design (0.59% to 3.41% of SG and 12.93% to 27.07% GSO). For the second stage, using a Centered Face Design - CFD, the resulting emulsion was sonicated at 90, 270, and 450 Watts at 5, 10, and 15 min. Finally, a validation was made. Emulsions were evaluated through microstructure, droplet size, kinetic stability, heat stress, and rheology. Micrographs of the first-stage emulsions showed droplets up to 3.8 μm diameter and a creaming index between 0.00% and 28.39% after 24 h. Optimization indicates that the higher the concentration of gum (3.5%) and GSO (25%), the more kinetically stable emulsions are produced. Ultrasonic emulsions showed no significant difference in droplet size and kinetic stability before 14 days of rest. Ultrasonic validation was made at 450 W for 6 min, resulting in emulsions stable for 20 days and with rheological characteristics interesting for food or cosmetic industries.

Resumo O Oxford Happiness Questionnaire-Short Form (OHQ-SF) é uma escala de 8 itens que avalia a felicidade e foi adaptada para uso com indivíduos espanhóis. No entanto, nenhum estudo examinou a sua validade estrutural e invariância de gênero em adultos jovens. Para verificar isso, as propriedades psicométricas do OHQ-SF foram analisadas em uma amostra de 625 universitários espanhóis (175 homens, 28%, e 450 mulheres, 72%), com faixa etária entre 18 e 29 anos (M = 20,80, DP = 2,40). Foram utilizadas adaptações espanholas do OHQ-SF, Purpose In Life Test-10 Items (PIL-10), Satisfaction With Life Scales (SWLS) e Seeking of Noetic Goals (SONG). O OHQ-SF apresentou consistência interna de 0,66, confiabilidade composta de 0,68, correlação média entre itens de 0,21 e correlações totais de itens variando de 0,27 a 0,52 (M = 0,36). Os procedimentos confirmatórios revelaram um ajuste excelente para o OHQ-SF (SBχ2(20) = 22,387, p = 0,320, CFI = 0,996, TLI = 0,995, RMSEA = 0,014) e invariância configural, métrica, escalar e estrita entre grupos de gênero. A diferença entre a média das mulheres (36,40, DP = 5,3) e a média dos homens (36,27, DP = 5,09) no OHQ-SF não foi significativa (t(623) = -0,285, p = 0,776). As correlações entre o OHQ-SF, o PIL-10, o SWLS e o SONG-8 foram fortes e significativas (ρ = 0,61, p < 0,001; ρ = 0,64, p < 0,001; e ρ = -. 38, p < 0,001 respectivamente). Estes resultados confirmam que a versão espanhola do OHQ-SF, utilizada com estudantes espanhóis no presente estudo, é uma escala confiável e válida.

Abstract The Oxford Happiness Questionnaire-Short Form (OHQ-SF) is an 8-item scale that assesses happiness, and it has been adapted for use with Spanish individuals. However, no study has examined its structural validity and gender invariance in young adults. To check this, the psychometric properties of the OHQ-SF were analyzed in a sample of 625 Spanish undergraduates (175 men, 28%, and 450 women, 72%), with an age range between 18 and 29 years (M = 20.80, SD = 2.40). Spanish adaptations of the OHQ-SF, Purpose In Life Test-10 Items (PIL-10), Satisfaction With Life Scales (SWLS), and Seeking of Noetic Goals (SONG) were used. The OHQ-SF showed an internal consistency of .66, a composite reliability of .68, an average inter-item correlation of .21, and total-item correlations ranging from .27 to .52 (M = .36). Confirmatory procedures revealed an excellent fit for the OHQ-SF (SBχ2(20) = 22.387, p = .320, CFI = .996, TLI = .995, RMSEA = .014), and configural, metric, scalar, and strict invariance across gender groups. The difference between the women’s mean (36.40, SD = 5.3) and the men’s mean (36.27, SD = 5.09) in the OHQ-SF was not significant (t(623) = -.285, p = .776). Correlations between the OHQ-SF, the PIL-10, the SWLS, and the SONG-8 were strong and significant (ρ = .61, p < .001; ρ = .64, p < .001; and ρ = -.38, p < .001 respectively). These results confirm that the Spanish version of the OHQ-SF, used with Spanish undergraduates in the present study, is a reliable and valid scale.

Resumo Existem problemas de cascas de concreto onde é imprescindível analisar as tensões das armaduras na fissura, como a verificação do Estado Limite Último de fadiga em lajes de tabuleiros de pontes e abertura de fissuras em reservatório de água. Em vista disso, este trabalho apresenta o modelo numérico denominado Modelo de Casca Fissurada (Cracked Shell Model – CSM), que possibilita determinar as tensões nas armaduras ortogonais de elementos de casca de concreto armado. O CSM utiliza o método lamelar, onde a espessura do elemento de casca é discretizada em lamelas de concreto sujeitas a um estado plano de tensões. As armaduras são avaliadas a partir do Modelo de Membrana Fissurada (Cracked Membrane Model - CMM), que considera o amolecimento do concreto à compressão e o efeito de enrijecimento à tração via Modelo de Banzo Tracionado (Tension Chord Model - TCM). A validação do CSM foi realizada com dados experimentais e numéricos de cascas disponíveis na literatura, no qual o modelo mostrou ser capaz de prever o comportamento completo de elementos de casca de concreto armado, com boa precisão e baixo custo computacional. Adicionalmente, foi conduzido um estudo sobre o Efeito de Membrana Comprimida em lajes de tabuleiro de pontes, o qual tende a aumentar a capacidade resistente dessas lajes. Com este estudo pode-se observar que o CSM, apesar do bom desempenho apresentado na fase de validação, por está baseado na teoria de placas finas de Kirchhoff (prática usual em muitos projetos) não conseguiu capturar esse efeito, subestimando a carga última, em média em 44%, em relação à ensaios experimentais. Esse artigo visa contribuir para o desenvolvimento de modelos numéricos de cascas de concreto armado, em problemas onde a tensão máxima da armadura é fundamental.

Abstract There are reinforced concrete problems where it is essential to analyze the reinforcement stresses at the crack, such as verifying the Fatigue Limit State in bridge deck slabs and crack opening in water tanks. In view of this, this work presents a numerical model called Cracked Shell Model (CSM), which enables the determination of stresses in the orthogonal reinforcement of concrete shell elements. The CSM uses the layered method, where the thickness of the shell element is discretized into concrete layers subjected to a plane stress state. The reinforcements are evaluated using the Cracked Membrane Model (CMM), which considers the compression softening of concrete and the tension stiffening effects via the Tension Chord Model (TCM). The validation of the CSM was carried out with experimental and numerical shell data available in the literature. It has been shown to be capable of predicting the complete behavior of reinforced concrete shell elements, with good accuracy and low computational cost. Additionally, a study was conducted on the Compressive Membrane Action (CMA) on bridge deck slabs, which tends to increase the load capacity of these slabs. With this study it can be observed that the CSM, despite the good performance presented in the validation phase, as it is based on Kirchhoff thin plate theory (usual practice in many projects) failed to capture this effect, underestimating the ultimate load by an average of 44% in relation to experimental tests. This article aims to contribute to developing numerical models of reinforced concrete shells, in problems where the maximum reinforcement stress is essential.
