To discover new bisamide compounds with insecticidal and fungicidal activities, 19 novel cyproflanilide derivatives containing 1,2,4-oxadiazole group were designed and synthesized according to the principle of biologically active factor splicing. Preliminary biological assay data indicated that the majority of target compounds demonstrated significant insecticidal activity against Lepidopteran pests. Meanwhile, compounds 5p and 5q showed 97.22 and 100% lethality against Tetranychus cinnabarinus at 400 mg L-1, which were better than cyproflanilide (41.11% at 400 mg L-1). In addition, it is exciting that we have achieved our initial goals as some of the target compounds exhibited both insecticidal and fungicidal activities. For instance, compounds 5b and 5c showed 59.26 and 74.07% fungicidal activities against Cucumber downy mildew at 400 mg L-1, as well as 100% insecticidal activity against Plutella xylostella and armyworm at 100 mg L-1. Compound 5h showed 100% insecticidal activity against armyworm at 10 mg L-1, and also displayed 66.67% fungicidal activity against Cucumber downy mildew at 400 mg L-1. The inhibition rate of compounds 5l and 5s against Cucumber downy mildew reached 88.89 and 96.30% at 400 mg L-1. This work showed the effectively fungicidal application of 1,2,4-oxadiazole group in bisamide compounds and provides insights for optimal structural design. 1 1,2,4oxadiazole 124oxadiazole oxadiazole 1,2,4 2 4 splicing pests Meanwhile p q 9722 97 22 97.2 40 L1, L1 L 1, L-1 41.11% 4111 41 11 (41.11 L1. .

Resumo Apenas na última década, a obra do engenheiro Uruguaio Eladio Dieste (1917-2000) vem ganhando disseminação acadêmica internacional, sendo que uma de suas principais contribuições para a concepção formal-estrutural na arquitetura e engenharia civil foi o desenvolvimento iterativo da tipologia estrutural das abóbadas gaussianas, cascas de dupla-curvatura estruturadas em cerâmica armada. Entretanto, não há registros de uma definição estabelecida para a geometria arquitetônica destas tipologias estruturais. Tampouco existem evidências concretas acerca da concepção e desenvolvimento projetual destas estruturas. Por conseguinte, o objetivo deste artigo é evidenciar as relações geométricas subjacentes nas abóbadas guassianas descontínuas projetadas e construídas por Eladio Dieste em cerâmica armada, a variação dominante desta tipologia estrutural. Esta análise foi conduzida através da modelagem paramétrica e da regressão polinomial de estudos de caso selecionados a partir de fontes primárias originais, justamente por estas ferramentas computacionais permitirem o correto manejo de geometrias tidas como formalmente complexas. A contribuição esperada para esta pesquisa reside em aprofundar o entendimento entre a relação do processo de projeto e a geometria resultante no objeto de estudo, assim como o entendimento da conformação geométrica desta tipologia estrutural desenvolvida por Eladio Dieste. década 19172000 1917 2000 (1917-2000 internacional formalestrutural formal gaussianas duplacurvatura dupla curvatura armada Entretanto estruturais estruturas conseguinte originais complexas estudo 1917200 191 200 (1917-200 191720 19 20 (1917-20 19172 1 2 (1917-2 (1917- (1917 (191 (19 (1 (

Abstract Only within the last decade, the works of Uruguay an Engineer Eladio Dieste (1917-2000) have been gaining international academic dissemination, one of whose main contributions in the realm of formal-structural conception within architecture and civil engineering reside in the iterative development of the structural typology of the gaussian vault shells in reinforced brickwork. However, there is not an established definition for this typology’s architectural geometry. Also, there is hardly any evidence of how such shells were designed. Therefore, the main objective, of this paper is to demonstrate the underlying geometric relationships in the discontinuous gaussian vault shells designed and built by Eladio Dieste in reinforced brickwork, the dominant typological variation within the object of study. This analysis was carried out by means of the parametric modeling and the polynomial regression of selected case studies from the primary sources, since such computational tools allow for the proper geometrical management of formally complex geometries. The expected contributions of this study reside in the deepening of the understanding of the relationship between the design process and the geometry of the object of study, as well as the understanding of the geometrical conformation of the structural typology conceived by Eladio Dieste. decade 19172000 1917 2000 (1917-2000 dissemination formalstructural formal brickwork However typologys s Also Therefore objective sources geometries 1917200 191 200 (1917-200 191720 19 20 (1917-20 19172 1 2 (1917-2 (1917- (1917 (191 (19 (1 (

Abstract The valorization and use of lignocellulosic biomass from food processing to obtain value-added products is crucial to improve sustainability and reduce waste management costs. This potential for cost reduction is a reason for optimism, as it allows agro-industrial waste to be transformed into valuable resources, contributing to the circular economy. This study focused on the compositional and structural characterization of eleven types of lignocellulosic biomass (LCB) to evaluate their potential in producing nanopolysaccharides and polyhydroxyalkanoates. Parameters such as humidity, ash, proteins, extractives, structural carbohydrates, and lignin were analyzed in passion fruit peels, artichoke bracts, asparagus peels, lemon peels, orange peels, avocado seed, potato peels, cassava peels, sugar cane bagasse, rice husk, and rice straw. The results showed that fruit peels and other waste had a high extractive content (28.05%), while the content of lignin and structural carbohydrates varied between 69.66% and 30.53% and 22.2% and 8.84%, respectively. In addition to the characterization, this BLC's potential for producing biopolymers was explored, highlighting its relevance in various industries such as food and materials engineering. These findings underline the importance of using local natural resources sustainably, opening new opportunities to develop innovative applications such as pickering emulsions, biodegradable packaging, aerogels, hydrogels, and functional foods. These applications represent promising areas for future research and technological development.

Resumen La valorización y utilización de la biomasa lignocelulósica proveniente del procesamiento de alimentos para la obtención de productos con valor añadido es crucial para mejorar la sostenibilidad y reducir costos de gestión de residuos, permitiendo transformar los desechos agroindustriales en recursos valiosos, contribuyendo a la economía circular. Este estudio se enfocó en la caracterización composicional y estructural de once tipos de biomasa lignocelulósica (BLC) con el fin de evaluar su potencial en la producción de nanopolisacáridos y polihidroxialcanoatos. Se analizaron parámetros como humedad, ceniza, proteínas, extractivos, carbohidratos estructurales y lignina en cáscaras de maracuyá, brácteas de alcachofa, cáscaras de espárrago, limón, naranja, semilla de palta, papa, yuca, bagazo de caña de azúcar, cáscara de arroz y paja de arroz. Los resultados mostraron que las cáscaras de frutas y otros residuos presentaron un alto contenido de extractivos (28,05%), mientras que el contenido de lignina y carbohidratos estructurales varió entre 69,66% y 30,53% y 22,2% y 8,84%, respectivamente. Además de la caracterización, se exploró el potencial de esta BLC para la producción de biopolímeros, destacando su relevancia en diversas industrias como la alimentaria y la ingeniería de materiales. En este sentido, estos hallazgos subrayan la importancia de utilizar recursos naturales locales de forma sostenible, abriendo nuevas oportunidades para desarrollar aplicaciones innovadoras como emulsiones pickering, envases biodegradables, aerogeles, hidrogeles y alimentos funcionales. Estas aplicaciones representan áreas prometedoras para futuras investigaciones y desarrollo tecnológico.

Adoption of automation has become the norm in the South African banking industry, owing to competition. Conventional banking institutions are uncertain of the possible adverse effects of integrating automation into banking processes to serve more customers with fewer resources. This study sought to investigate and model the extent to which the integration of automation could be the exogenous factor of the nine endogenous factors identified in this study. The five most prominent banking institutions in South Africa, were used as a case study. The study used a quantitative approach, and 223 bank employees were selected to contribute to the questionnaire survey, and the primary data were analysed using the structural equation modelling (SEM) technique to test the proposed hypotheses. The secondary information was extracted from the banks' annual integrated reports and fact sheets to generate additional insights into the primary data findings. The findings revealed that service delivery automation is a significant and direct predictor of productivity, efficiency, flexibility, operations costs, and the generation of new job opportunities (positive effects). Similarly, the adoption of bank automation was found to be significantly related to the generation of job losses, the changing nature of work, unbalanced demand for required skills, and inequality in wages of employees, which are described as adverse effects.

As gevolg van mededinging, het die aanneming van outomatisering die norm in die Suid-Afrikaanse bankbedryf geword. Konvensionele bankinstellings is onseker oor die moontlike nadelige gevolge van die integrasie van outomatisering in bankprosesse om meer kliënte met minder hulpbronne te bedien. Hierdie studie poog om die mate waarin die integrasie van outomatisering die eksogene faktor van die nege endogene faktore wat in hierdie studie geïdentifiseer is, te ondersoek en te modelleer. Die vyf mees prominente bankinstellings in Suid-Afrika, is as gevallestudie gebruik. Die studie het 'n kwantitatiewe benadering gebruik, en 223 bankwerknemers is gekies om by te dra tot die vraelysopname, en die primêre data is ontleed deur gebruik te maak van die strukturele vergelyking modellering (SEM) tegniek om die voorgestelde hipoteses te toets. Die sekondêre inligting is uit die banke se jaarlikse geïntegreerde verslae en feiteblaaie onttrek om bykomende insigte in die primêre databevindinge te genereer. Die bevindinge het aan die lig gebring dat dienslewering outomatisering 'n beduidende en direkte voorspeller is van produktiwiteit, doeltreffendheid, buigsaamheid, bedryfskoste en die generering van nuwe werksgeleenthede (positiewe effekte). Net so is gevind dat die aanvaarding van bankoutomatisering beduidend verband hou met die generering van werkverliese, die veranderende aard van werk, ongebalanseerde vraag na vereiste vaardighede en ongelykheid in lone van werknemers, wat as nadelige gevolge beskryf word.

This study delves into the dynamic interplay between GeoGebra, a prominent interactive digital tool, and science, technology, engineering, and mathematics (STEM) cognition, focusing on teachers. Anchored by the objective to unravel how GeoGebra influences conceptual understanding and visualisation, the research hypothesises that GeoGebra significantly influences cognitive outcomes in STEM cognition. Thus, aiming to assess the hypothesis that GeoGebra significantly influences cognitive outcomes, a Multi-Group Analysis (MGA) using Partial Least Squares-Structural Equation Modelling (PLS-SEM) was employed. Data was collected through a survey designed to capture the experiences and interactions of 71 teachers with GeoGebra. The significant direct pathways (Analogical Comparison Principle (ACP) and Error and Misconceptions Reflection Principle (EMR) and between Mathematical and Computational Algorithms (MCA) and Analogical Comparison Principle (ACP)) established empirical evidence to the theory that GeoGebra can facilitate conceptual understanding as well as cognitive development. Additionally, the indirect pathways with no significant effects such as Mathematical Cognition (MAS) to ACP to EMR was indicative of the fact that influence of GeoGebra operates more through direct interactions with the software as opposed to through mediated learning processes. The conclusion is that influence of GeoGebra is not uniform across all contexts, indicative of the fact that factors such as geographical location play a critical role in shaping the software's effectiveness in enhancing STEM education. In sum, while GeoGebra is a potent interactive digital tool for enhancing STEM cognition, the results call for tailored strategies in integrating digital tools like GeoGebra, by considering the specific needs of different learning context, particularly paying attention to the contrast between urban and rural educational settings.

Resumen: En el presente estudio, se analiza el desempeño sísmico de un sistema dual de hormigón armado (pórticos y muros especiales) con diferentes niveles de irregularidad torsional. Se plantean tres arquetipos, cada uno con un nivel de irregularidad torsional distinto (IT 1.0, IT 1.2 e IT 1.4) con la finalidad de evaluar el efecto de la irregularidad torsional en el desempeño sísmico. Los elementos estructurales de los arquetipos cumplen con el diseño sismorresistente. Además, se tomó en cuenta los factores de sobre-resistencia y amplificación dinámica para determinar el corte de diseño en los muros estructurales. Se realizaron análisis estático y dinámicos no lineales para cuantificar las respuestas globales y locales de cada uno de los modelos. Los modelos analíticos de muros estructurales son calibrados en función de los datos obtenidos en ensayos experimentales existentes, de esta manera se valida los elementos tipo fibra (infrmFB) usados y los parámetros de los modelos constitutivos de los materiales. Se realizan análisis dinámicos incrementales (IDA) para cada uno de los arquetipos con los once registros sísmicos seleccionados de la base del PEER. Las curvas IDA son desarrolladas con dos parámetros de demanda ingenieril: derivas de piso y deformaciones unitarias. Finalmente, se elaboran las curvas de fragilidad para los niveles de desempeño de ocupación inmediata, seguridad de vida y prevención de colapso, y se determinan los coeficientes de margen con la finalidad de cuantificar las probabilidades de alcanzar los niveles de desempeño mencionados.

Abstract: This research evaluates the seismic performance of a dual reinforced concrete system with different levels of torsional irregularity. Three archetypes are proposed, each of them with a different level of torsional irregularity (IT 1.0, IT 1.2 and IT 1.4) in order to evaluate the effect of torsional irregularity on seismic performance. The structural elements of the archetypes comply with the seismic design. In addition, the factors of overstrength and dynamic amplification were considered to determine the design shear force in the structural walls. Linear static and nonlinear dynamic analysis were performed to quantify the global and local responses of each of the models. The analytical models of structural walls are calibrated based on the data of existing experimental tests, thus validating the fiber-type elements (infrmFB) used and the parameters of the constitutive models of the materials. Incremental dynamic analysis (IDA) is performed for each of the archetypes with the eleven seismic records selected from the PEER database. IDA curves are developed with two engineering demand parameters: story drifts and strains. Finally, the fragility curves are elaborated for the immediate occupancy, life safety, and collapse prevention performance levels, and the margin ratio are determined to quantify the probabilities of reaching a certain level of performance.

ABSTRACT This research focuses on the evaluation of the structural symmetry of the Zamora-Loja bridge, a crucial infrastructure for the Loja and Zamora areas. Given the concern for excessive vibrations, meticulous geophysical tests were carried out. The main objective was to analyze the bridge's response to various loading conditions, especially its symmetry, essential for safety and efficiency. A test truck was used to drive over different areas of the bridge, recording revealing variations in its behavior. The results highlighted a 17.93% variation in structural behavior when the truck traveled through the lane equipped with the geophone, indicating an asymmetrical load distribution. In contrast, the lane without the geophone showed a variation of 8.82%, suggesting a different structural response. When traveling in the center lane, the variation was 16.30%, reflecting an intermediate response to centered loads. Complementing these findings, a finite element based computational model was used, incorporating real bridge data. The comparison between actual and computational results provides a comprehensive perspective of the bridge behavior and is an invaluable tool for future interventions. These tests not only provide a clear view of the integrity and safety of the bridge, but also set a precedent for the use of advanced technologies in the evaluation of critical infrastructure.

RESUMEN Esta investigación se centra en la evaluación de la simetría estructural del puente Zamora-Loja, una infraestructura crucial para las áreas de Loja y Zamora. Dada la preocupación por vibraciones excesivas, se llevaron a cabo ensayos geofísicos meticulosos. El objetivo principal fue analizar la respuesta del puente a diversas condiciones de carga, especialmente su simetría, esencial para la seguridad y eficiencia. Se utilizó un camión de prueba para transitar por diferentes zonas del puente, registrando variaciones reveladoras en su comportamiento. Los resultados destacaron una variación del 17.93% en el comportamiento estructural cuando el camión transitó por el carril equipado con el geófono, indicando una distribución asimétrica de la carga. En contraste, el carril sin el geófono mostró una variación del 8.82%, sugiriendo una respuesta estructural diferente. Al transitar por el carril central, la variación fue del 16.30%, reflejando una respuesta intermedia a cargas centradas. Complementando estos hallazgos, se empleó un modelo computacional basado en elementos finitos, que incorporó datos reales del puente. La comparación entre resultados reales y computacionales proporciona una perspectiva integral del comportamiento del puente, siendo una herramienta invaluable para futuras intervenciones. Estos ensayos no solo ofrecen una visión clara de la integridad y seguridad del puente, sino que también establecen un precedente para el uso de tecnologías avanzadas en la evaluación de infraestructuras críticas.

Abstract This article presents a formulation for the optimization problem that minimizes the CO2 emission of pile caps with variations of geometry and pile position. The problem is defined by the design variables: concrete pile cap dimensions, rebar ratio, concrete compressive strength, the number of piles, the diameter, and length. The environmental impact was chosen as the objective function, taking CO2 emission as the main parameter. The design procedure was based on the ABNT NBR 6118:2014 (2014), and by the formulation proposed by Blévot & Frémy (1967). Also, the soil structure interaction between the cap and the piles was considered in the optimization problem. The problem was implemented using MATLAB (2016) and solved via a Genetic Algorithm native to the program. Results obtained from numerical examples were compared with structural designs solutions located in the Grande Vitória metropolitan area, Espírito Santo, Brazil and validated with a commercial software. The analyses indicate that design optimizations of pile caps considering the compressive strength of concrete, the diameter and length of piles and the optimal geometry of the pile caps may lead to significant reductions of material consumption, and consequently, a reduction of environmental impacts.

Abstract Education moves through the adaptation of teaching-learning processes to 21st century society and the integration of Digital Educational Resources. In the History of Cuba discipline program, for the Computer Science Engineering career, teachers are guided to lead students towards scientific knowledge, human and political values, and transform their own teaching-learning process. The teacher has the responsibility of appropriating the technologies to choose and use Digital Educational Resources that support, facilitate the process and improve study habits. This work aims to present an instrument to evaluate the design and use of Digital Educational Resources in the virtual course of the History of Cuba discipline at the University of Computer Sciences. To carry it out, the historical-logical, analytical-synthetic, inductive-deductive, content analysis and systemic structural-functional methods were used as methods. The DER must adapt to the possibilities of each institution, taking advantage of the potential of the support. Your evaluation should not be limited to examining its characteristics. For them to be truly effective in the teaching process, both the context in which they will be used and their influence on student learning must be taken into account.

Abstract Universities' engagement with the community and external institutions is particularly important in the current context. Society demands from academic institutions a real commitment to developing solutions to prioritize environmental problems to achieve a genuine social and economic transformation. This research aims to analyze the influence of motivation and organizational support on the results of engagement with the community and external institutions of teachers and students of postgraduate programs. A survey was carried out on 50 participants from doctoral programs in science and engineering at a public university in Chile, selected through intentional non-probabilistic sampling. The data obtained were analyzed through a Partial Least Squares Structural Equation Modeling (PLS-SEM) approach. The findings show that motivational factors directly, strongly, and significantly influence individual engagement results with the community and external institutions and act as mediator variables for organizational support. The most relevant motivations are related to the desire to strengthen the disciplinary field, collaborate in research, and generate knowledge with an impact on society and the territory. In conclusion, the study provides valuable exploratory findings on the relationship between motivation and organizational support, as well as the effectiveness of engagement actions with the community and external institutions. These findings provide key information for higher education institutions to develop policies and strategies aimed at improving their engagement with external stakeholders.

Resumo No contexto atual, o envolvimento das universidades com a comunidade e instituições externas é particularmente importante. A sociedade exige que as instituições acadêmicas se comprometam verdadeiramente no desenvolvimento de soluções para os problemas prioritários da comunidade, visando alcançar uma transformação social e econômica real. Esta pesquisa tem como objetivo analisar a influência da motivação e do suporte organizacional nos resultados da Extensão universitária de professores e estudantes de programas de pós-graduação. Foi realizado um levantamento com 50 participantes de programas de doutorado em ciências e engenharia de uma universidade pública no Chile, selecionados por amostragem não probabilística intencional. Os dados obtidos foram analisados por meio de um Modelo de Equações Estruturais de Mínimos Quadrados Parciais (PLS-SEM). Os resultados mostram que os fatores motivacionais têm uma influência direta, forte e significativa nos resultados individuais de extensão, e também atuam como uma variável mediadora do suporte organizacional. As motivações mais relevantes estão relacionadas ao desejo de fortalecer o campo disciplinar, colaborar em pesquisas e gerar conhecimento com impacto na sociedade e no território. Em conclusão, o estudo fornece descobertas exploratórias valiosas sobre a relação entre motivação e suporte organizacional, bem como a eficácia das ações de extensão universitária. Essas descobertas fornecem informações importantes para as instituições de ensino superior desenvolverem políticas e estratégias destinadas a melhorar seu envolvimento com seus grupos de interesse externos.
