Abstract This article aims to investigate a unique path in the reception and translation of Antonio Gramsci’s ideas in Brazil. This work attempts to reconstruct Fernando Henrique Cardoso’s political thought during the Brazilian military dictatorship and democratic transition (1964-1988), focusing on his interpretation and use of Antonio Gramsci’s ideas to analyze state formation, social classes and politics in Brazil. The paper argues that the Gramscian concepts are central to Cardoso’s political thought in three phases of Gramscian refraction: (i) between 1964 and 1974, in the thesis of the Brazilian bourgeoisie’s dependent hegemony; (ii) between 1974 and 1983, in the argument of the Brazilian state as the “Modern Prince” as a concept for the analysis of the agrarian-industrial-military coalition in the post-1964 period; and (iii) from 1983 to 1988, in the definition of the Brazilian economic and military elites’ behavior as a authoritarian-scletortic transformism in the face of the pressures for the democratization of the political regime. Cardoso’s uses of Gramscian concepts are creative at all these moments. That is, the Brazilian thinker draws on Gramscian concepts to create his own lexicon to employ in the analysis of Brazilian politics. The article therefore explores not only the reception, but also the translation of Gramsci’s ideas in Fernando Henrique Cardoso.

Abstract While early studies on electoral strategies argue that Brazilian system encourages “personal vote” and the creation of geographically located electoral strongholds, latest studies show that the most effective electoral strategy is vote dispersion. According to the contextual perspective, people vote for candidates whose political messages they have access to and who correspond to the demands of the places where they live. Based on the construction of a database regarding the legislative elections from 2010 to 2018 we seek to interpret the results found using this perspective. Starting from the hypothesis of a vote ruled by the way information is diffused in space, we find that most candidates have their strongest vote in their municipality’s electoral domicile, that those with only municipal experience show a voting pattern consistent with the “friends and neighbors” effect, and that there is a party coordination in the formation of candidate lists.Keywords: localism; electoral concentration; electoral strategies; electoral behaviour; electoral geography. personal strongholds dispersion perspective live 201 space municipalitys municipality s domicile friends neighbors effect lists.Keywords listsKeywords lists Keywords localism concentration behaviour geography 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

The Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

RESUMO: O objetivo deste trabalho foi extrair lignina de Eucalyptus sp. licor negro kraft e avaliar a influência de sua adição nas propriedades do adesivo lignina-fenol-formaldeído. Os adesivos foram sintetizados em diferentes porcentagens de massa de fenol por lignina, denominados adesivos lignina-fenol-formaldeído nas proporções de 25, 30, 50, 75 e 80%. Os parâmetros avaliados nos adesivos foram pH, teor de sólidos totais, teor de compostos orgânicos, teor de compostos inorgânicos, tempo de gelatinização e comportamento do adesivo na linha de cola. O pH variou de 10,63 a 11,65. Para o teor de sólidos totais foi encontrado o valor de 53 a 69%. Os teores de compostos orgânicos variaram de 51 a 75% e de inorgânicos de 25 a 49%. Observou-se que com a adição da macromolécula na formulação do adesivo, o teor de sólidos totais e orgânicos foi reduzido proporcionalmente enquanto o de sólidos inorgânicos foi elevado. O tempo de gelatinização foi reduzido devido à adição de lignina. As menores proporções de adição apresentaram melhor penetração e fluidez na interface com a madeira. A lignina kraft extraída do licor negro kraft de eucalipto é um ótimo adesivo com potencial para substituir parcialmente o fenol derivado do petróleo, com grande potencial para uso e aplicação nos setores aeronáutico e automotivo, no processo de colagem de peças estruturais.

ABSTRACT: The objective of this research was to extract lignin from Eucalyptus sp. kraft black liquor and to evaluate the influence of its addition on the properties of the lignin-phenol-formaldehyde adhesive. The adhesives were synthesized at different phenol mass percentages by lignin, called lignin-phenol-formaldehyde adhesives in the proportions of 25, 30, 50, 75 and 80%. The parameters evaluated in the adhesives were pH, total solid content, organic compound content, inorganic compound content, gelatinization time and adhesive behavior in the glue line. The pH ranged from 10.63 to 11.65. For the total solid content was found the value of 53 to 69 %. The contents of organic compounds ranged from 51 to 75% and inorganic from 25 to 49%. It was observed that with the addition of macromolecule in the adhesive formulation, the total and organic solid content was reduced proportionally while the inorganic solid was high. The gelatinization time was reduced due to the addition of lignin. The lower proportions of addition presented better penetration and fluidity in interface with the wood. The kraft lignin extracted from eucalyptus kraft black liquor is a great adhesive with potential to partially replace petroleum-derived phenol, with great potential for use and application in the aeronautical and automotive sectors, in the bonding process of structural parts.

This study evaluated the potential of naphthoxazoles derived from lapachol as fluorescent deoxyribonucleic acid (DNA) probes. We synthesized three 2-substituted naphthoxazoles: one with a phenyl group (LOX1), and two with 2-hydroxyphenyl (LOX2) and 4-fluorophenyl (LOX3) groups, respectively. The compounds were synthesized using the Debus-Radziszewski reaction between the lapachol and aldehydes. The quantum yield (Φf) was determined using the classical relative method with 4’,6-diamidino-2-phenylindole (DAPI) as the standard, and the fluorescence lifetime (τf) was measured with a lifetime fluorescence spectrometer. The naphthoxazoles exhibited low fluorescence emission and consequently low values of Φf in their free form, demonstrating behavior similar to that of DAPI. These compounds displayed notably large Stokes shifts (approximately 340 nm) and the τf in the nanosecond range. DNA binding studies were conducted by monitoring changes in the absorption properties of naphthoxazoles in the absence and presence of calf thymus DNA at different concentrations. The results indicated that naphthoxazoles interacted with DNA through groove binding. LOX2 exhibited a binding constant (Kb) of 2.70 × 104 M-1, indicating strong binding to the biomolecule. These findings underscore the potential of LOX1, LOX2, and LOX3 as candidates for use as fluorescent DNA probes.

In this study, it was investigated chitosan (CHIT) films in the presence or absence of cellulose nanofibers (CNF) and silver nanoparticles (AgNP), whose chemical interactions involving metallic surfaces were characterized by surface-enhanced Raman scattering (SERS) spectroscopy. Changes in the morphology were analyzed through atomic force microscopy (AFM) and scanning electron microscopy (SEM). SEM and AFM micrographs revealed that the incorporation of CNF significantly altered CHIT films, leading to changes in the polymer topography and surface texture due to intimal interactions between CNF and the CHIT matrix. Raman spectra of CHIT and CNF/CHIT films showed similar profiles, reflecting comparable molecular structures of both modified biopolymers. However, SERS spectra of both films, after recovering with AgNP, demonstrated distinct spectral profiles. Innovatively, density functional theory (DFT) calculations of an oligomer model for CHIT were employed to assign the vibrational modes observed in the SERS spectra, which allowed identify key interactions between CHIT moieties and AgNP surfaces. SERS results revealed that chemical adsorption of CHIT on AgNP surfaces occurs through interactions of glycosidic oxygen and amino groups. Such findings provide insights into the structural and chemical behavior of this nanocomposite, highlighting its potential for advanced biological applications. study (CHIT (CNF , (AgNP) surfaceenhanced enhanced (SERS spectroscopy (AFM SEM. .

Computational predictive approaches present themselves as an attractive alternative in the search for new compounds that may present toxic or growth regulatory activity in Aedes aegypti. Aspergillus species is a producer of secondary metabolites with diverse biological activities. In this study, it was possible to evaluate the pharmacokinetic and toxicological properties in silico, as well as the prediction of the insecticidal biological activities of the juvenile hormone of natural substances produced by the genus Aspergillus. Initially, 187 molecules were cataloged from various species of Aspergillus spp., and only seven molecules of indole alkaloids were found to exhibit a toxic dose 50% (TD50) after conducting toxicity predictions. The molecular dynamic simulation trajectories were utilized to study parameters such as root mean square deviation, root mean square fluctuation, radius of gyration and intermolecular hydrogen bond to understand the behavior and stability of proposed compounds in the binding pocket of the target protein. The N-β-acetyltryptamine molecule showed a binding affinity value of –8.100 ± 0.200 kcal mol-1, which classifies the compound as a potential insecticidal agent against the Aedes aegypti vector. silico Initially 18 spp spp. 50 TD50 TD (TD50 predictions deviation fluctuation protein Nβacetyltryptamine N β acetyltryptamine 8100 8 100 –8.10 0200 0 200 0.20 mol1, mol1 mol 1, 1 mol-1 vector 5 TD5 (TD5 810 10 –8.1 020 20 0.2 mol- (TD 81 –8. 02 2 0. –8 –

RESUMO Objetivo: Examinar a associação entre o tempo de tela autorreportado e os sintomas de estresse, ansiedade e depressão em adolescentes. Métodos: Foi realizado estudo com delineamento transversal com 982 adolescentes entre 12-15 anos, matriculados na rede pública de ensino da cidade de Jacarezinho (PR). Para mensurar o tempo de tela, os adolescentes responderam à pergunta: “Considerando um dia típico, quanto tempo você passa assistindo TV, jogando videogame, usando computador ou smartphone?”. O questionário DASS-21 (versão curta) foi utilizado para avaliar os sintomas de depressão, ansiedade e estresse. Análises brutas e ajustadas (idade, sexo e nível de escolaridade materna) entre tempo de tela e indicadores de saúde mental foram realizadas por meio do modelo de regressão linear generalizado, com distribuição de Poisson, adotando a significância de p<0,05. Resultados: Maiores sintomas depressivos foram observados em adolescentes com tempo de tela de 4–6 horas/dia (RP 1,35, IC95% 1,13–1,61) e ≥6 horas/dia (RP 1,88, IC95% 1,62–2,19) quando comparados com seus pares com ≤2 horas/dia. O mesmo foi observado para os sintomas de ansiedade com tempo de tela de 4–6 horas/dia (RP 1,23, IC95% 1,04–1,46) e ≥6 horas/dia (RP 1,50, IC95% 1,28–1,77); e estresse, com 4–6 horas/dia (RP 1,25, IC95% 1,08–1,44) e ≥6 horas/dia (RP 1,49, IC95% 1,30–1,71), também comparados com seus pares com ≤2 horas/dia. Conclusões: O tempo de tela foi associado positivamente com os sintomas de depressão, ansiedade e estresse em adolescentes. Atenção especial deve ser dada àqueles que passam mais de quatro horas por dia em frente a uma tela. Objetivo Métodos 98 1215 12 15 12-1 anos PR. PR .

ABSTRACT Objective: To examine the associations between self-reported screen time and symptoms of stress, anxiety, and depression in adolescents. Methods: A cross-sectional study was conducted with 982 adolescents aged between 12 and 15 years, enrolled in public schools in Jacarezinho (PR), Brazil. Screen time was assessed by the question “Considering a typical day, how much time do you spend watching TV, playing videogame, using computer or smartphone?” The DASS-21 questionnaire (short form) was used to assess symptoms of depression, anxiety, and stress. Crude and adjusted analyses (age, sex, and maternal level of education) between screen time and mental disorders symptoms were performed using general linear regression models, with Poisson distribution, with significance level at p<0.05. Results: Higher depressive symptoms were observed in adolescents who reported screen time of 4–6 hours/day (PR 1.35, 95%CI 1.13–1.61) and ≥6 hours/day (PR 1.88, 95%CI 1.62–2.19), compared with their pairs with <2 hours/day. The same was observed for anxiety symptoms with screen time of 4–6 hours/day (PR 1.23, 95%CI 1.04–1.46) and ≥6 hours/day (PR 1.50, 95%CI 1.28–1.77); and stress, with 4–6 hours/day (PR 1.25, 95%CI 1.08–1.44) and ≥6 hours/day (PR 1.49, 95%CI 1.30–1.71), also compared with their pairs with <2 hours/day. Conclusions: Screen time was positively associated with depressive, anxiety, and stress symptoms in adolescents.

ABSTRACT The purpose of this study was to analyze the influence of attention and skepticism in the evaluation of false market discourse with an environmental appeal (greenwashing). The theoretical support for the research was based on the study of the attention process (understood in terms of pre-attention and attention), as well as the practice of greenwashing and consumer skepticism. The methodological procedure adopted a hypothetical-deductive approach, carried out through two face-to-face experiments (n=129 and n=159) with a 2 factorial design (attention/pre-attention) x 2 (present/absent skepticism), with the measurement of four interest metrics (attribute evaluation, judgment about the practice of greenwashing, emotional reaction to the advertisement, and environmental purchase behavior), added to eye tracking. One-way ANOVA was used for one-dimensional analyzes and general linear model (GLM) ANOVA for multivariate analyses, with Tukey's post hoc test. As a result, it was possible to observe a better evaluation of the practice of greenwashing when pre-attentiveness and the absence of skepticism were combined, which sets up a potential scenario for the influence of this false marketing discourse on consumer behavior. greenwashing. .

RESUMO O trabalho teve como objetivo analisar a influência da atenção e do ceticismo na avaliação do falso discurso mercadológico com apelo ambiental (greenwashing). O suporte teórico da pesquisa assentou-se no estudo do processo da atenção (compreendido em termos de pré-atenção e atenção), assim como da prática de greenwashing e o ceticismo do consumidor. O procedimento metodológico adotou uma abordagem hipotético-dedutiva, realizada por meio de dois experimentos presenciais (n=129 e n=159) com desenho fatorial 2 (atenção/pré-atenção) x 2 (ceticismo presente/ausente), com a mensuração de quatro métricas de interesse (avaliação dos atributos, julgamento acerca da prática de greenwashing, reação emocional ao anúncio e comportamento ambiental de compra), somada ao monitoramento ocular (eyetracker). Foram empregadas a ANOVA one-way para as análises unidimensionais e a ANOVA pelo modelo linear geral (GLM) para as análises multivariadas, com o teste post hoc de Tukey. Como resultado, foi possível observar uma melhor avaliação da prática de greenwashing quando da junção da pré-atenção e da ausência do ceticismo, o que configura um cenário de potencialidade da capacidade de influência desse falso discurso mercadológico no comportamento do consumidor. greenwashing. .

ABSTRACT: China is the biggest muskmelon producing country across the world. Extreme application of fertilizer during planting of muskmelon poses a serious threat to the environment and food safety, so how to promote farmers to use organic fertilizer has become an important topic. This study creatively introduced green awareness into the extended framework of theory of planned behavior to explore the decisive factors of muskmelon farmers’ behavior intention to apply green organic fertilizer. The structural equation model is used for investigating behavior intention of 543 muskmelon farmers in Leting County, China. The results suggested that both subjective norm and green awareness can affect muskmelon farmers’ behavior intention positively and significantly. When the subjective norm increases by 1 standard deviation, the farmers’ intention increases by 1.028 standard deviation; for every 1 standard deviation increase in green awareness, the farmers’ intention increased by 0.703 standard deviation.

RESUMO: A China é o maior país produtor de melão em todo o mundo. A aplicação extrema de fertilizantes durante o plantio de melão representa uma séria ameaça ao meio ambiente e à segurança alimentar, portanto, como promover os agricultores a usar fertilizante orgânico verde tornou-se um tópico importante. Este estudo introduziu criativamente a consciência verde no quadro estendido da teoria do comportamento, planejado para explorar os fatores decisivos da intenção dos agricultores de melão de aplicar fertilizante orgânico verde. O modelo de equações estruturais é usado para investigar a intenção de comportamento de 543 agricultores de melão no Condado de Leting, China. Os resultados sugerem que tanto a norma subjetiva quanto a consciência verde podem afetar positiva e significativamente o comportamento dos produtores de melão. Quando a norma subjetiva aumenta em 1, o desvio padrão, a intenção do agricultor aumenta em 1,028 desvio padrão. Para cada aumento de 1 desvio padrão na consciência verde, a intenção dos agricultores aumentou em 0,703 desvio padrão.

ABSTRACT Deformation intensity analysis for mechanical parts are very important data for machine design. For farm machines, these parameters present difficulties for determination due to its particularities. The Machinery industry searches for advanced technologies to determine the mechanical behavior of parts. This article shows the analysis of the reliability in the application of the laser triangulation technique (LTT) to determine the deformation of the mechanical elements of farm machines. A flat cutting disc with standardized dimension was selected as the object of study, as it is commonly used in farm machines, exhibiting a simple geometry made of steel, making the analysis procedure easier both for experimental execution and for data validation. Displacements of 1.0 mm to 10 mm were applied on the specimen. The theoretical behavior of specimen displacement was defined by finite element modelling with same condition of loading and dimension to compare the generated data by the experimental tests. Results indicated a displacement with maximum variation of 2.56% between experimental data and theoretical results and were considered satisfactory. LTT was able to determine deformation curve behavior of machine elements. It was concluded that Laser Triangulation Technique (LTT) was satisfactory to determine the deformation of a specimen. design machines particularities (LTT study steel validation 1 0 1. tests 256 2 56 2.56 25 5 2.5 2.

Silver film is commonly used to examine the structure and composition of molecules due to its surface-enhanced Raman scattering (SERS) effect. A simple method for preparing SERS silver films is proposed in this paper by electrodeposition in an amide-based liquid mixture (urea-acetamide-LiBr). The electrochemical behavior of silver in urea-acetamide-LiBr mixture was studied by cyclic voltammetry (CV) and chronoamperometry. It was found that the nucleation mechanism of silver shifts to instantaneous nucleation under diffusion control with increasing overpotential and temperature. The energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) investigations confirmed that the obtained deposits are pure silver. Scanning electron microscopy (SEM) analysis showed that the morphology of the silver deposits depends on the deposition potential and temperature. Rhodamine 6G was used as probe molecules for SERS experiments, showing that these new active substrates have high sensitivity to SERS response with high enhancement factors, of approximately 107, and enable Raman scattering even for diluted solutions. surfaceenhanced surface enhanced (SERS effect amidebased amide based ureaacetamideLiBr. ureaacetamideLiBr urea acetamide LiBr .

ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28–2.40), consume alcohol (OR1.43; 95%CI 1.05–1.94), have worse sleep quality (OR 1.94; 95%CI 1.28–2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08–1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22–2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

Even though ammonia is a natural component of aquatic environments, elevated concentrations indicate pollution and environmental degradation. Consequently, efficient analytical methods for monitoring ammonia levels are crucial for preserving water quality. Voltammetry offers a sustainable approach for NH3 quantification, combining good analytical performance with low sample and reagent consumption, minimizing waste generation. However, despite these advantages, the voltammetric determination of ammonia remains relatively unexplored. Therefore, this study investigated the electrochemical behavior of NH3 in alkaline solutions using a non-modified Pt electrode and evaluated the performance of differential pulse voltammetry (DPV) and square wave voltammetry (SWV) for NH3 determination. DPV provided superior performance, with limits of detection and quantification of 0.79 µmol L-1 (0.011 ppmN) and 2.6 µmol L-1 (0.036 ppmN), respectively, which comply with the maximum allowable ammonia concentration in natural waters according to Brazilian and European regulations. The voltammetric method successfully quantified ammonia in tap and river water samples, providing results concordant with the established Berthelot spectrophotometric method, at a 95% confidence level. Additionally, it is simple and fully accessible to non-electrochemist since no sophisticated procedures for electrode modification are needed. Finally, the high analytical performance of the proposed method makes it valuable for pollution monitoring in aquatic environments. environments degradation Consequently quality NH consumption generation However advantages unexplored Therefore nonmodified non modified (DPV SWV (SWV 079 0 79 0.7 L1 L 1 L- 0.011 0011 011 (0.01 ppmN 26 2 6 2. 0.036 0036 036 (0.03 ppmN, , respectively regulations samples 95 level Additionally nonelectrochemist electrochemist needed Finally 07 7 0. 0.01 001 01 (0.0 0.03 003 03 9 0.0 00 (0.
