Abstract (Introduction): Bycatch and discards are a socio-environmental concern that threatens the sustainability of marine life and fishing grounds. Approaches to this problem have focused on biological and/or ecological aspects. We considered it necessary to explore the problem from the social dimension and for this purpose we explored social representations. (Objective): The aim of this study is to explore the social representations of bycatch and discards in a group of businessmen and workers in the capture stage of the Argentine industrial fishing activity. We ask how they evaluate bycatch and fishing discards, what are their causes and if they observe possible solutions. (Methodology): Within the framework of a project of the Federal Fishing Council, we conducted focus groups with businessmen, business chambers, SOMU workers and captains of the industrial fishing activity. (Results): The results of the focus groups conducted in 2021 reveal three main causes of this problem. First, the lack of reliable data on actual discard levels raises concerns about sustainability and overfishing. Second, the low utilization of selectivity devices is attributed to their operational inefficiency and possible labour barriers. Finally, economic and organizational pressures, such as company profitability and workers’ salaries, justify the discard of non-target species, exacerbating the problem. (Conclusions): The work contributes to an understanding of the main reasons for bycatch and discards, which is essential to advance solutions. We understand that solutions are not simple and involve a sincere debate among stakeholders.

Resumen (Introducción): Las capturas incidentales y los descartes pesqueros son una preocupación socioambiental que amenaza la sostenibilidad de la vida marina y de los caladeros. Los abordajes a esta problemática estuvieron centrados en aspectos biológicos y ecológicos. Consideramos necesario explorar la problemática desde la dimensión social y para ello, exploramos las representaciones sociales. (Objetivo): El objetivo de este estudio fue explorar las representaciones sobre capturas incidentales y descartes pesqueros en un grupo de empresarios y trabajadores de la etapa de captura de la actividad pesquera industrial argentina, específicamente, cómo evalúan este problema, sus causas y posibles soluciones. (Metodología): En el marco de un proyecto del Consejo Federal Pesquero, se realizaron grupos focales con seis cámaras empresariales y personal jerárquico de empresas asociadas, así como trabajadores del SOMU y capitanes que operan en alta mar. (Resultados): Los resultados de los grupos focales realizados en 2021 revelaron tres principales causas de dicha problemática. Primero, la falta de datos confiables sobre los niveles reales de descarte genera preocupaciones sobre la sostenibilidad y la sobreexplotación. Segundo, la escasa utilización de dispositivos de selectividad se atribuye a su ineficacia operativa y a posibles barreras laborales. Finalmente, las presiones económicas y organizacionales, como la rentabilidad de las empresas y los salarios de los trabajadores, justifican el descarte, exacerbando el problema. (Conclusiones): El trabajo aporta a un entendimiento sobre las razones de la captura incidental y los descarte, esencial para avanzar en soluciones. Entendemos que las soluciones no son simples e implican un sincero debate entre actores.

Abstract The literature on the relationship between public policies, political parties, and presidential voting strongly focuses on analyses of income transfer programs, which limits the understanding of how different aspects of policy design and implementation relate to the partisan-electoral game. Through linear regressions applied to all Brazilian municipalities, this article analyzes the electoral dynamics of the Minha Casa Minha Vida (My House My Life) housing policy program. From the program’s inception to the 2014 elections, it details results by policy modalities, implementation phases, and adherence to the housing deficit. The results show that municipalities governed by parties belonging to the federal government’s coalition did not receive more housing units, except for the modality targeted at the poorest electorate. Moreover, the Worker’s Party’s (PT) electoral return was positive where the program’s implementation was related to the housing deficit, particularly in 2010. policies programs partisanelectoral partisan game Life program s 201 elections modalities phases deficit governments government units electorate Moreover Workers Worker Partys Party PT (PT 2010 20 2

In recent years, the field of coordination chemistry has experienced a surge in interest regarding the synthesis and characterization of coordination complexes for diverse applications. This study is dedicated to investigating coordination compounds resulting from the interaction of nonsteroidal anti-inflammatory drugs (NSAIDs) with metal ions. The study research places significant emphasis on understanding the stability and thermal behavior of these coordination compounds. The utilization of thermoanalytical techniques is crucial in achieving this goal. Thermal analysis and thermokinetics provide valuable insights into the underlying mechanisms, kinetics, and energetics of these reactions, thereby facilitating the optimization of synthesis procedures. The research employs concurrent techniques, namely thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), to explore the thermal stability and decomposition pathways of these coordination compounds. Thermokinetic models and optimization methodologies are subsequently applied to identify key reaction parameters. The primary aim of this research is to unveil the thermal behavior, stability, and reaction kinetics of aceclofenac coordination compounds, thus contributing significantly to the understanding of thermokinetics and thermal analysis in the domain of coordination chemistry. Specifically, this study is focused on aceclofenac coordination complexes involving lanthanum and gadolinium, with the ultimate goal of advancing the field of coordination chemistry. years applications antiinflammatory anti inflammatory NSAIDs (NSAIDs ions mechanisms reactions procedures TG (TG DSC, DSC , (DSC) parameters Specifically gadolinium (DSC

Gold and platinum bimetallic nanoparticles, Au@PtNPs, have gained attention due to their plasmonic properties. The controlled synthesis of Au@PtNPs involves complex parameters, and the resulting synergy between Au and Pt introduces possibilities for tailoring their properties. This study explores the effects of key-parameters of synthesis (gold core diameters, reaction time, and Pt concentration) on the final properties of Au@PtNPs. Gold nanoparticles of varying diameters were synthesized and used as cores for the reduction of hexachloroplatinic acid, forming a surrounding shell of Pt nanoparticles. The parameters were systematically tuned to understand their impact on morphology, dimension, stability, and plasmonic properties of Au@PtNPs. Increasing Pt precursor concentration resulted in thicker and denser Pt shells, broadening the localized surface plasmon resonance (LSPR) band and improving Au@PtNPs stability. These properties are essential for applications such as photothermal treatment. The synthesis achieved satisfactory products within just 1 h of Pt4+ reduction at mild temperature without using surfactants. Only limited changes in plasmonic properties were observed after 4 h of synthesis, suggesting an optimal reaction period. Manipulating Au core diameter provided LSPR band control, with smaller cores exhibiting greater broadening towards the infrared region. This systematic exploration provided valuable insights for understanding key-parameters governing the synthesis and properties of Au@PtNPs.

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stands for being the most serious epidemic (so far) of the 21st century. However, only a few computational studies have investigated the molecular mechanisms underlying the neutralization of the spike protein by antibodies of different classes. Hence, bioinformatic methods were employed to unravel the factors contributing to the remarkable neutralization capacity exhibited by specific antibodies. Initially, crystallographic structures of IgA monomeric / dimeric, IgG, and IgM antibodies binding with the receptor-binding domain region of the SARS-CoV-2 spike protein were retrieved. Subsequently, rigid molecular docking and molecular dynamic simulations were performed over 100 ns with explicit water solvation. Lastly, an energy decomposition was conducted to estimate the binding affinity using the last frames from molecular dynamics. The results revealed a higher binding affinity for both monomeric and dimeric forms of IgA antibodies against the spike protein. Additionally, a greater number of hydrogen bonds were observed during their interaction with the spike protein, as well as greater structural instability along the time and especially a more thermodynamically favorable interaction affinity. In this way, the research contributes a small piece to the complex puzzle of understanding the humoral immune response induced by the SARS-CoV-2 virus.

ABSTRACT Grain production is steadily increasing; however, the static storage capacity remains inadequate in Brazil. The lack of proper facilities and the precarious and inadequate storage conditions lead to post-harvest losses due to factors interacting with the grains, causing their deterioration. Chemical treatments are commonly used to reverse these effects; however, their replacement with natural substances has been sought due to environmental and human health concerns. The objective of this review was to discuss a sustainable strategy for treating stored grains, focusing on the use of natural compounds with bioactive properties, such as antifungal, antioxidant, and insecticidal activities, with potential for further studies. Natural compounds with useful properties for application in grain storage were outlined. Research on the use of natural compounds in grain treatment is still in its early stages, requiring progress in identifying new promising compounds, understanding the mechanisms of action, and developing and optimizing effective extraction, application, and formulation processes to make the use of these substances viable. increasing however Brazil postharvest post harvest grains deterioration effects concerns antifungal antioxidant activities studies outlined stages action extraction viable

RESUMO Este estudo foca no desempenho de vacas para produção de carne, criadas nos pântanos do Paraguai, examinando cinco genótipos bovinos; Brahman, Brangus, Nelore, bem como duas raças locais em risco de extinção. O principal objetivo é identificar e classificar variáveis fenotípicas que incluem variáveis sanguíneas, clínicas, de pelagem e saúde, demonstrando ligação causal com o peso vivo das vacas analisadas. Inicialmente, foram identificadas correlações elevadas entre diferentes variáveis incluídas neste estudo, e, então, utilizando técnicas avançadas de aprendizado de máquina e a aplicação de explicações aditivas de Shapley (SHAP), foi proporcionado um entendimento mais profundo dos fatores fortemente associados à adaptabilidade nestes ambientes, e, portanto, o respectivo desempenho zootécnico. A associação entre o componente genotípico bovino ligado à estação do ano mostrou ser o fator influente mais predominante sobre o peso vivo bovino. Variáveis como comprimento do pelo, hematócrito, fosfatase, fósforo, creatina phosphokinase, creatinina, proteína, cortisol, cálcio e a presença de endoparasitas foram destacadas, demonstrando sua importância hierárquica para a seleção animal. Os modelos de ML são ferramentas eficazes para estabelecer hierarquias de relevância em multivariáveis fenotípicas complexas, o que é crucial em programas de melhoramento genético em diferentes espécies zootécnicas, bem como em ambientes especiais e específicos, como os pântanos. carne Paraguai bovinos Brahman Brangus Nelore extinção sanguíneas clínicas saúde analisadas Inicialmente então SHAP, SHAP , (SHAP) portanto zootécnico pelo hematócrito fosfatase fósforo phosphokinase creatinina proteína cortisol destacadas animal complexas zootécnicas específicos (SHAP

ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands.

Selenium-containing compounds exhibit diverse biological activities, such as antioxidative, anti-inflammatory, and cancer preventive effects. Using Caenorhabditis elegans as a model organism, we assessed the toxicity, neuroprotective, antioxidant properties, and impact on longevity of 11 selenoacetylenes. Their toxicity and bioactivities varied based on molecular structure. Selenoacetylenes with butyl substituents were toxic to Galleria mellonella larvae. The presence of but-3-in-2-ol radical increased antiprotozoal activity against Tetrahymena pyriformis. Compared to the positive control (Nimitz® EC), selenoacetylenes were less toxic to nematode worms and eggs. Selenoacetylenes significantly reduced amyloid beta (Aβ) paralysis in C. elegans CL4176 worms, increased longevity by 18 to 22%, along with improving survival after oxidative or thermal stress. Galantamine, showed inferior results. These findings enhance our understanding of selenoacetylenes on neuroprotection, antioxidant activity, and longevity in C. elegans. Future mammalian studies will further elucidate mechanisms and explore the potential therapeutic use of selenoacetylenes in treating Alzheimer’s disease and longevity.

High-density polyethylene (HDPE) geomembranes are commonly used as an environmental protection liner due to their good chemical and mechanical resistances and low cost. Ultraviolet (UV) radiation is an essential issue in durability studies for pond applications. This study evaluated a 1.5-mm thick HDPE geomembrane exposed to ultraviolet fluorescent radiation for 8760 h in a laboratory and thermoanalytical and physical analyses were conducted towards the understanding of its performance after exposure. According to the results, although the geomembrane maintained the ductile behavior, it showed a 52.48% final decrease in stress crack resistance (SCR) compared to virgin SCR. Moreover, a considerable antioxidant depletion occurred after 8760 h exposure shown by the Std. OIT (standard oxidative-induction time) results, demonstrating a Std. OIT value decrease of 89.19% compared to the virgin Std. OIT. Such a behavior contributed to the susceptibility of thermal effects in the DSC (differential scanning calorimetry) curves and the losses observed in the SCR values, attesting the geomembrane’s oxidative degradation mechanism occurred and changed the polymer’s structure.

In the present article, the scientific journey that led to the development of the Nernst equation, a cornerstone in modern electrochemistry, is discussed. The paper not only explores historical achievements but also traces the evolution of scientific ideas and highlights the key figures who laid the conceptual and experimental groundwork for the seminal contributions of Nernst to the understanding of electrochemical systems. In this exploration, particular attention is paid to the examination of the first three articles published by Nernst between 1888 and 1889. These essential works marked the inception of the engagement of Nernst with the Leipzig Physical Chemistry circle, comprising the distinguished quartet: van’t Hoff, Arrhenius, Ostwald, and Nernst himself. Furthermore, the present study examines the intricate relationship between the Nernst equation and the four basic laws of Thermodynamics, all in an approach accessible to undergraduate students. A concise review elucidates the interpretation and significance of these foundational thermodynamic principles and explain how they hold the formulation of the Nernst equation. article electrochemistry discussed systems exploration 188 1889 circle quartet vant van t Hoff Arrhenius Ostwald himself Furthermore Thermodynamics students 18 1

Chemometrics is gaining more and more space in universities and industry. To contribute to the development and expansion of principal component analysis (PCA) teaching proposals, this work evaluated the answers of the students to a questionnaire and presented a didactic-pedagogical proposal that can contribute to solving the principal doubts achieved by students in the PCA interpretation. Based on data collected in a semi-open questionnaire, the proposal was developed based on methodological principles of historical-critical pedagogy, containing the objectives, the problems surrounding the topic, and the cultural instruments necessary for understanding and interpreting PCA in the discipline of chemometrics by using new resources and instruments, especially free software, Chemostat. This proposal covers topics related to the concept of chemometrics and PCA, the explanation of the data set, pre-processing, use of Chemostat software, and analysis of principal components. It is hoped that this proposal can promote a better understanding concerning PCA on the part of students, as well as effective incorporation of the phenomena that involve this tool and its applications, and interpretation. Likewise, it is expected that this didactic-pedagogical proposal can support new teaching practices in chemometrics subjects in higher education. industry (PCA proposals didacticpedagogical didactic pedagogical interpretation semiopen semi open historicalcritical historical critical pedagogy objectives topic software set preprocessing, preprocessing pre processing, processing pre-processing components applications Likewise education

RESUMO: A osteologia desempenha um papel indispensável para o conhecimento dos padrões de normalidade das diversas espécies, sendo a base para o entendimento zoológico. Mazama nana é bastante conhecido no Brasil, porém descrições morfológicas básicas acerca da espécie são escassas, enquanto Subulo gouazoubira, revalidação atual de Mazama gouazoubira, também é incidente no Brasil e, atualmente, tem sido alvo de diversos estudos filogenéticos. Nesse escopo, no presente estudo, foram preparadas, osteologicamente, 19 cabeças de cervídeos (16 Subulo gouazoubira e três Mazama nana) e, em seguida, tomografias computadorizadas (TCs) foram realizadas a fim de aprimorar as formas de avaliação de acidentes ósseos, além de estruturas internas e forames mediante técnicas de reconstrução em três dimensões (3D) devido a difícil visibilidade em peças intactas. Posteriormente, realizou-se um comparativo entre as reconstruções, fotografias digitais e secções tomográficas transversais do crânio, o qual possibilitou a visualização de peculiaridades e exclusividades anatômicas, como a presença da fenestra nasolacrimomaxilar, detalhamento dos seios paranasais e arquitetura de ossos finos, além do formato exclusivo dos ossos cranianos, em comparação a outras espécies, que apresentam um fenótipo único e genuíno.

ABSTRACT: Osteology plays an indispensable role in understanding the normal patterns of different species, serving as the foundation for zoological understanding. Mazama nana is well-known in Brazil; however, basic morphological descriptions of the species are scarce, while Subulo gouazoubira, currently revalidated as Mazama gouazoubira, is also prevalent in Brazil and has recently been the subject of various phylogenetic studies. In this respect, in the present study, 19 cervid heads (16 Subulo gouazoubira and three Mazama nana) were osteologically prepared. Next, computed tomographies (CTs) were performed to enhance the assessment of bone accidents, as well as internal structures and foramina through three-dimensional (3D) reconstruction techniques due to the difficult visibility in intact specimens. A comparison was then made between the reconstructions, digital photographs, and CT cross-sections of the skull, which enabled the visualization of anatomical peculiarities and exclusivities, such as nasolacrimal-maxillary fenestra, paranasal sinuses, and thin bone architecture, as well as the unique shape of cranial bones, compared to other species that exhibit a unique and genuine phenotype.

RESUMO Este artigo propõe um modelo conceitual para avaliar como a motivação materialista dos consumidores impacta as características sociais (prestígio e conspicuidade) que geram Status para produtos tecnológicos inovadores, que podem levar à intenção de consumo. O estudo utilizou uma abordagem quantitativa para testar um modelo conceitual utilizando a modelagem de equações estruturais com o uso do PLS - SEM. Os resultados indicam que o prestígio do produto e a percepção de conspicuidade do produto medeiam a motivação materialista dos consumidores, o que afeta o status social proporcionado pelo produto ao indivíduo. Da mesma forma, a percepção de inovação e o status do produto medeiam a relação entre conspicuidade e prestígio percebido em relação à intenção de consumo. Esta pesquisa fornece insights importantes sobre as fortes relações entre as características sociais do produto tecnológico que levam em conta os valores dos indivíduos. Como consequência, este estudo contribui diretamente na compreensão de status e valores sociais influenciando a intenção de consumo de produtos tecnológicos, demonstrando o quanto a inovação traz elementos de valoração do indivíduo que a possui. inovadores SEM forma indivíduos consequência possui

ABSTRACT This article proposes a conceptual model to assess how consumers' materialistic motivations impact social characteristics (prestige and conspicuity) that generate status for innovative technological products, which can lead to consumption intention. The study used a quantitative approach to test a conceptual model using structural equation modeling through PLS - SEM. The results indicate that product prestige and perception of product conspicuity mediate consumers’ materialistic motivations, which affects the social status provided to the individual by the product. Likewise, perception of innovation and product status mediate the relationship between conspicuity and perceived prestige in relation to consumption intention. This research yields important insights regarding the strong relations between the social characteristics of technological products that take into account individuals’ values. Consequently, this study enhances understanding of how status and social value influence the intention to consume technological products, demonstrating the extent to which innovation brings elements of value to individuals who own the product in question. consumers SEM Likewise values Consequently question
