The exploration of carbon steel corrosion inhibition in 0.5 mol L-1 H2SO4 using extracts from Hymenaea courbaril (HC) has resulted in significant findings. Extracts from the bark, leaves, fruit pulp, and fruit shell have all proven to be effective corrosion inhibitors, as demonstrated through surface studies and electrochemical methods. Infrared spectroscopy and high-performance liquid chromatography have identified the presence of phenolic compounds, which are known to have corrosion-inhibiting potential. UV-Vis spectroscopy has further revealed the adsorption of extract species on the steel surface. Electrochemical studies have confirmed the inhibition of corrosion, allowing to propose mechanisms of both chemisorption and physisorption. X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) have provided evidence of the formation of an inhibitory layer, further supporting the inhibition of corrosion. Langmuir isotherms have indicated favorable adsorption of the extracts, while reduced surface roughness suggests improved protection of the steel surface. Activation energy calculations have demonstrated an increase in energy barriers, resulting in slower corrosion rates. These findings suggest that extracts from Hymenaea courbaril show promise as eco-friendly corrosion inhibitors, with potential industrial applications. Further research is needed to optimize the extraction process and fully understand the inhibition mechanisms. 05 0 5 0.

RESUMO: Entender aspectos da germinação de sementes de espécies nativas do Cerrado pode auxiliar na escolha de espécies a serem utilizadas na restauração de ecossistemas degradados. Portanto, o estudo teve como objetivo verificar o efeito de cápsulas biodegradáveis na germinação de sementes de três espécies arbóreas típicas de fisionomias florestais do Cerrado (Enterolobium contortisiliquum, Anadenanthera colubrina e Dipteryx alata). O experimento foi conduzido em casa de vegetação, com dois tratamentos: semeadura no interior de cápsulas biodegradáveis e semeadura direta na superfície do substrato. Duas sementes de cada espécie foram utilizadas por tratamento, as quais foram acomodadas em sacos plásticos com substrato arenoso oriundo da classe Neossolo Quartzarênico. Para cada tratamento, foram utilizados cinco blocos (repetições), com 20 sacos plásticos cada. A casa de vegetação teve condições controladas de temperatura e umidade relativa. Dentro das cápsulas, os resultados mostraram que as sementes de baru, angico-branco e tamboril apresentaram germinação de 97%, 42% e 12%, respectivamente. Por outro lado, na semeadura direta, a germinação foi de 15% para baru, 21% para angico-branco e 8% para tamboril. Os resultados indicam que o uso de cápsulas biodegradáveis favorece a germinação das espécies do Cerrado estudadas. Assim, tanto a utilização das cápsulas quanto as espécies elencadas são recomendadas em projetos de restauração ecológica.

ABSTRACT: A good grasp of the different facets of seed germination of the plant species native to the Cerrado will facilitate the selection of species that can be used to restore degraded ecosystems. Hence, the objective of the current study was to confirm the ways biodegradable capsules affect the germination of the seeds of three tree species typical of the physiognomies of the Cerrado forest (Enterolobium contortisiliquum, Anadenanthera colubrina and Dipteryx alata). The experiments, conducted in a greenhouse, included two treatments: seeding performed inside biodegradable capsules and direct seeding on the substrate surface. Two seeds from each of the species were sown in plastic bags containing the Quartzarenic Neosol class of substrates. Using five replicates for each treatment resulted in 20 plastic bags for each. The greenhouse conditions included controlled temperature and relative humidity. Inside the capsules, the findings revealed that the baru, angico-branco and tamboril seeds germinated at the rates of 97%, 42%, and 12%, respectively. However, during direct seeding, germination rates for baru, angico-branco and tamboril were 15%, 21% and 8%. From the findings, it is evident that when biodegradable capsules are used, the germination of all three Cerrado species investigated is favoured. Thus, both capsules and the cited species can be recommended for projects of ecological restoration.

ABSTRACT Purpose: To evaluate the predictive value of initial intraocular pressure difference of the detached and fellow eyes of patients with complex rhegmatogenous retinal detachment on postoperative persistent ocular hypotony. Methods: This retrospective observational study included 538 eyes of 538 unilateral complex rhegmatogenous retinal detachment patients with a proliferative vitreoretinopathy grade of C-1 or higher, treated with silicone oil endotamponade following pars plana vitrectomy. The patients were divided into Group A (patients having silicone oil removal without ocular hypotony; n=504) and Group B (patients with persistent ocular hypotony following silicone oil removal [n=8, 23.5%] and with retained silicone oil [n=26, 76.5%] due to the risk of persistent ocular hypotony; total n=34). Ocular hypotony was defined as an intraocular pressure of <6 mmHg on two or more occasions. Patients’ demographics, including age, sex, and follow-up time, and ocular characteristics, including ocular surgical and trauma history, initial and final best-corrected visual acuity, intraocular pressure and initial intraocular pressure difference of the detached and fellow eyes, and anatomical success rates and postoperative complications, were retrospectively collected from the electronic patient files. Results: The initial intraocular pressure was significantly lower in the detached eyes of Group B than in Group A (8.3 ± 3.5 vs. 12.9 ± 3.3, p<0.001). Also, the initial intraocular pressure difference was significantly higher in Group B than in Group A (8.9 ± 3.2 vs. 2.2 ± 2.7mmHg, p<0.001). The receiver operating characteristic curve analysis showed that the cutoff value of the initial intraocular pressure difference was 7.5mmHg for the risk of persistent ocular hypotony. The most influential factors on postoperative persistent ocular hypotony in the binary logistic regression analysis were the initial intraocular pressure difference and the need for a retinectomy. Conclusion: In eyes with complex rhegmatogenous retinal detachment treated with pars plana vitrectomy and silicone oil tamponade, the initial intraocular pressure difference could be of value in predicting postoperative persistent ocular hypotony and could guide surgeons on the decision of silicone oil removal.

ABSTRACT: Based on the data of China’s overseas arable land investment in 47 countries along the “Belt and Road”, the Tobit model is used to analyze the effects of cultural distance and friendship cities on the production rates of contracted arable land in China’s overseas arable land investment. This study provided theoretical basis and empirical support for promoting China’s agricultural “going abroad” and improving the production rates of contracted arable land in China’s overseas arable land investment. The results show that differences in cultural distance, power distance and the degree of uncertainty avoidance have significant positive effects on the production rates of contracted arable land in China’s overseas arable land investment, and differences in individualism have a significant negative effect on the production rates. Friendship city has a positive but insignificant effect on the production rates, meanwhile, it also weaken the positive impact of cultural distance on production rates of contracted arable land in China’s overseas arable land investment. The proportion of joint ventures with host country, the economic level and institutional environment of the host country will all have an impact on the production rates. Finally, recommendations are proposed to promote the production rates of contracted arable land, such as focusing on the positive role of cultural distance, establishing friendship cities, and investing host countries with high potential precisely.

RESUMO: Com base nos dados do investimento da China em terras aráveis no exterior em 47 países ao longo do “Cinturão e Rota”, o modelo Tobit é utilizado para analisar os efeitos da distância cultural e das cidades amigas nas taxas de produção de terras aráveis contratadas no investimento da China em terras aráveis no exterior. Os resultados mostram que as diferenças na distância cultural, na distância de poder e no grau de prevenção de incertezas têm efeitos positivos significativos sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China, e as diferenças no individualismo têm um efeito negativo significativo sobre as taxas de produção. As cidades amigas têm um efeito positivo, mas insignificante, sobre as taxas de produção, enquanto estas podem enfraquecer o impacto positivo da distância cultural sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China. A proporção de investimento cooperativo entre a China e o país anfitrião, o nível econômico e o ambiente institucional do país anfitrião terão um impacto sobre as taxas de produção. Por fim, são propostas recomendações para promover as taxas de produção das terras aráveis contratadas, tais como a concentração no papel positivo da distância cultural, a criação de cidades da amizade e o investimento em países de acolhimento com elevado potencial.

RESUMO A aplicação de esgoto sanitário utilizando o gotejamento subsuperficial contribui para mitigar os problemas atuais de disponibilidade de água e produção de alimento. Objetivou-se avaliar o feijão-caupi recebendo esgoto sanitário por gotejadores operando com diferentes vazões e profundidades. Os gotejadores operaram com as vazões de 1,6 e 3,8 L h-1 e foram instalados nas profundidades de 0, 5, 10, 15, 20, 25 e 30 cm. O feijão-caupi foi cultivado em vasos de 65 L preenchidos com solo argiloso em casa de vegetação. Utilizou-se esgoto sanitário sintético e a quantidade aplicada nos vasos foi baseada no elemento limitante, que no caso foi o nitrogênio, para o cultivo do feijão-caupi. O manejo da irrigação foi realizado com sondas de TDR. Avaliou-se a germinação e as respostas fisiológicas e morfologia das raízes do feijão-caupi. A ascensão capilar, quando a água foi aplicada em profundidade, não foi suficiente para umedecer de maneira uniforme a superfície do solo. As variáveis de germinação apresentaram um decréscimo em função do aumento das profundidades de instalação dos gotejadores. A distribuição da água com o aumento da profundidade dos emissores foi responsável pelos prejuízos nas respostas fisiológicas e morfológicas das raízes feijão-caupi. As vazões dos gotejadores não afetaram a germinação do feijão-caupi. Utilizar o sistema de irrigação por gotejamento subsuperficial não foi apropriado para o feijão-caupi nas condições deste estudo. alimento Objetivouse Objetivou se feijãocaupi feijão caupi 16 1 6 1, 38 3 8 3, h1 h h- 0 5 10 15 20 2 cm vegetação Utilizouse Utilizou limitante nitrogênio feijãocaupi. caupi.

ABSTRACT The application of sanitary sewage using subsurface drip irrigation contributes to mitigating the current problems of water availability and food production. The aim in this study was to evaluate cowpea receiving sanitary sewage through drippers operating at different flow rates and depths. The drippers operated at flow rates of 1.6 and 3.8 L h-1 and were installed at depths of 0, 5, 10, 15, 20, 25, and 30 cm. Cowpea was grown in 65 L pots filled with sandy clay soil in a greenhouse. Synthetic sanitary sewage was used and the amount applied to the pots was based on the limiting element, which in this case was nitrogen, for growing cowpea. Irrigation was managed using TDR probes. Germination and the physiological responses and morphology of cowpea roots were assessed. Capillary rise, when water was applied in subsurface, was not sufficient to evenly moisten the soil surface. The germination variables decreased as a result of the increase in drip installation depths. The distribution of water as the depth of the emitters increased was responsible for the damage to the physiological and morphological responses of cowpea roots. The flow rates of the drippers did not affect the germination of cowpea. Using the subsurface drip irrigation system was not appropriate for growing cowpea under the conditions of this study. production 16 1 6 1. 38 3 8 3. h1 h h- 0 5 10 15 20 25 cm greenhouse element nitrogen probes assessed rise surface 2

RESUMO: Objetivou-se avaliar a eficácia do sulfato de magnésio e cetamina em reduzir o requerimento de propofol, remifentanil e o resgate analgésico pós-operatório de gatas submetidas à ovariohisterectomia eletiva. Trinta gatas foram pré-medicadas com acepromazina (0,05 mg/kg) e morfina (0,3 mg/kg), intramuscular, e induzidas a inconsciência com propofol para intubação orotraqueal. As infusões contínuas (IC) de propofol e remifentanil foram iniciadas e os animais foram aleatoriamente alocados em três grupos: grupo sulfato de magnésio (MG) que recebeu bolus (50 mg/kg) e IC (80 mg/kg) de sulfato de magnésio; grupo cetamina (KG) que recebeu bolus (0,5 mg/kg) e IC (1,8 mg/kg/h) de cetamina; grupo controle (CG) que recebeu bolus e IC de solução salina 0,9%. As funções cardiovasculares e respiratórias, o tempo de extubação e a pontuação de resgate pós-operatório foram registrados e descritos com nível de significância de 95% (P < 0.05). O tempo de infusão dos tratamentos foi de 21,5 ± 3,4 e 21,0 ± 2,4 minutos no KG e MG, respectivamente (P = 0.194). As taxas de infusões de remifentanil (P = 0.336) e propofol (P = 0.716) foram similares entre grupos. Na análise de dor pós-operatória as escalas não demonstraram diferenças entre grupos quanto a número de resgates, pontuação de resgate ou tempo para o primeiro resgate. Em conclusão, os protocolos propostos foram seguros e efetivos. Contudo, o sulfato de magnésio e cetamina não demonstraram analgesia pós-operatória adicional ou efeitos adjuvantes anestésicos significativos.

ABSTRACT: This study assessed the efficacy of magnesium sulfate and ketamine hydrochloride in reducing the demand for propofol, remifentanil, and postoperative rescue analgesia in cats undergoing elective ovariohysterectomy. Thirty cats were premedicated with acepromazine (0.05 mg/kg) and morphine (0.3 mg/kg) intramuscularly and induced to unconsciousness with propofol for orotracheal intubation. The continuous infusion (CI) of propofol and remifentanil were started and animals and were randomly allocated into three groups: the magnesium sulfate group (MG) received one bolus (50 mg/kg) and CI (80 mg/kg/h) of magnesium sulfate; the ketamine group (KG) received bolus (0.5 mg/kg) and CI (1.8 mg/kg/h) of ketamine hydrochloride; the control group (CG) received bolus and CI of 0.9% saline solution. Cardiovascular and respiratory functions, extubation time, and rescue postoperative scores were assessed and data were described with a significance level of 95% (P < 0.05). The infusion period of treatments was 21.5 ± 3.4 and 21.0 ± 2.4 minutes in the KG and MG, respectively (P = 0.194). The infusion rates of remifentanil (P = 0.336) and propofol (P = 0.716) were similar between groups. Analysis of the postoperative pain scales revealed no significant intergroup differences in rescue frequency, rescue score, and time to the first rescue analgesia. In conclusion, the proposed protocols were safe and effective, yet it is noteworthy that both magnesium sulfate and ketamine failed to demonstrate significant additional postoperative analgesic or adjuvant anesthetic effects.

ABSTRACT The correct use of tyres on agricultural tractors, in respect of the terrain and the type and internal pressure of the tyre, are factors that influence the performance of the tractor. The aim of the present study was to evaluate the operating performance of an agricultural tractor fitted with two types of traction device (radial and diagonal tyres) at different pressures, and operating on soil with two levels of moisture. The experiment was conducted on a dystrophic Red Yellow Argisol, with tests to evaluate the performance of the tyres under specific working conditions. Tractive power and tractive force, wheel slip and fuel consumption were evaluated. For each of the conditions under evaluation, the radial configuration showed better performance than the diagonal configuration, the effect being more significant at the lower pressure and under low soil moisture. The use of radial tyres led to an increase in traction capacity and drawbar power, with a reduction in fuel consumption, especially at higher slip rates. tractors tyre pressures moisture Argisol force evaluated evaluation rates

This research aims to develop a precise and efficient dispersive solid-phase microextraction (DSPE) technique using third-generation polyamidoamine (PAMAM) dendrimer-grafted nanoparticles to quantify benzoylurea pesticides in green tea, black tea, and oolong tea infusions. The extraction efficiency is optimized through single-factor adjustments of key parameters, including adsorbent quantity (5-20 mg), adsorption duration (5-20 min), desorbent identity (methanol, acetonitrile), volume (100-600 μL), sodium chloride concentration (0-10%, m/v), and sample solution pH (3-8). The optimized method demonstrates linearity in the range of 2-500 μg L-1, with limits of detection (LODs) ranging from 0.6-1.5 μg L-1 and limits of quantification (LOQs) from 2.0 5.0 μg L-1. Recovery rates of 81.2-96.0% are achieved, with intra-day relative standard deviations (RSDs) of 1.4-2.8% and inter-day relative standard deviations of 2.0-3.9%, indicating high accuracy and repeatability. The successful application of detecting residues in commercial tea samples underscores the strong potential of the technique to determine benzoylurea analyte levels. solidphase solid phase DSPE (DSPE thirdgeneration third generation PAMAM (PAMAM dendrimergrafted dendrimer grafted infusions singlefactor single factor parameters 520 5 20 (5-2 mg, mg , mg) min, min min) methanol, methanol (methanol acetonitrile, acetonitrile acetonitrile) 100600 100 600 (100-60 μL, μL μL) 010%, 010 0 10%, 10 (0-10% m/v, mv m/v m v m/v) 38. 38 3 8 .

RESUMO Santa Catarina é um importante produtor de banana, responsável por 722 toneladas anuais. Para cada 1.000 kg de banana colhida, são gerados aproximadamente 3.000 kg de pseudocaule, 650 kg de cascas e 350 kg de frutos rejeitados. Estudos avaliaram a utilização de resíduos de banana para produção de bioetanol. Resíduos sólidos como bagaço de pseudocaule de banana, cascas de banana e vinhaça (resíduo de caldo fermentado) são produzidos nesse processo. Este estudo teve como objetivo quantificar e caracterizar esses resíduos para produção de biogás e metano. Cascas de banana e vinhaça foram melhores por conterem menor teor de sólidos totais e relações C:N (carbono:nitrogênio) favoráveis (10 - 30:1), proporcionando maior potencial bioquímico de metano (260 mLCH4 gvs -1) em comparação ao pseudocaule de bananeira bagaço (201 mLCH4 gvs -1). No entanto, a vinhaça apresentou alto teor de sulfeto de hidrogênio (0,0783%), necessitando de dessulfurização do biogás gerado para seu uso seguro. No geral, os resultados indicam que o bagaço do pseudocaule da banana, as cascas de banana e a vinhaça têm potencial substancial para a produção de biogás e metano devido às suas altas taxas de degradação. A composição do biogás atende aos critérios de utilização, com concentrações adequadas de metano e dióxido de carbono, destacando a viabilidade desses resíduos para geração de energia e contribuindo para a sustentabilidade no cultivo da banana. 72 anuais 1000 1 000 1.00 colhida 3000 3 3.00 65 35 rejeitados bioetanol resíduo fermentado processo CN C N carbononitrogênio carbono nitrogênio (carbono:nitrogênio 10 (1 301, 301 30 , 30:1) 260 (26 mLCH -1 201 (20 1. . entanto 0,0783%, 00783 0,0783% 0 0783 (0,0783%) seguro geral degradação 7 100 00 1.0 300 3.0 6 ( 30:1 26 (2 20 0078 0,0783 078 (0,0783% 3. 30: 2 007 0,078 07 (0,0783 0,07 (0,078 0,0 (0,07 0, (0,0 (0, (0

ABSTRACT Santa Catarina is a significant banana producer, responsible for 722 tons annually. For every 1,000 kg of bananas harvested, approximately 3,000 kg of pseudostem, 650 kg of peels, and 350 kg of rejected fruit are generated. Studies have evaluated the use of banana residues for bioethanol production. Solid residues like banana pseudostem bagasse, banana peels, and vinasse (fermented broth residue) are produced during this process. This study aimed to quantify and characterize these residues for biogas and methane production. Banana peels and vinasse were more suitable for containing lower total solids content and favorable C:N (carbon:nitrogen) ratios (10-30:1), yielding higher biochemical potential of methane (260 mLCH4 gvs -1) compared to banana pseudostem bagasse (201 mLCH4 gvs -1). However, vinasse had a high hydrogen sulfide content (0.0783%), necessitating desulphurization for safe biogas use. The results indicate that banana pseudostem bagasse, banana peels, and vinasse have substantial potential for biogas and methane production due to their high degradation rates. The biogas composition meets the criteria for use, with adequate methane and carbon dioxide concentrations, highlighting the viability of these residues for energy generation and contributing to sustainability in banana cultivation. producer 72 annually 1000 1 000 1,00 harvested 3000 3 3,00 65 35 generated fermented residue process CN C N carbonnitrogen nitrogen (carbon:nitrogen 10301, 10301 10 30 , (10-30:1) 260 (26 mLCH -1 201 (20 1. .

RESUMO Embora os separadores espirais estáticos sejam eficientes na remoção de partículas de formas e densidades variadas, eles frequentemente descartam sementes de alta qualidade fisiológica. Isso levou ao surgimento de dispositivos que possibilitam a rotação, permitindo assim um controle mais preciso sobre a separação das frações de sementes. O objetivo deste trabalho foi avaliar a qualidade física e fisiológica de sementes de soja separadas em frações qualificadas e descartadas por um separador espiral rotativo. O equipamento utilizado para os testes operou em diferentes velocidades de rotação, processando até 1,2 Mg h-1. Foram utilizados 27 sacos de 30 kg de sementes. Os tratamentos foram constituídos por dois fatores: velocidades de rotação (nula, 5 e 10 rpm) e fluxos de alimentação (0,3, 0,6 e 1,2 Mg h-1), com três repetições. Foram utilizadas sementes de soja da cultivar CZ 37B51 IPRO (safra 2022-2023) com 13% de umidade. A velocidade nula resultou nos maiores descartes de sementes (até 40%), especialmente na maior taxa de fluxo de alimentação. Uma velocidade de 5 rpm também resultou em grandes decartes.

ABSTRACT Although static spiral separators are efficient in removing particles of varying shapes and densities, they often discard seeds of high physiological quality. This has led to the emergence of devices that enables rotation, thus allowing more precise control over separation of seed fractions. The objective of this work was to assess the physical and physiological quality of soybean seeds separated into qualified and discarded fractions by a rotary spiral separator. The device used for the tests operated at different rotation speeds, processing up to 1.2 Mg h-1. Twenty-seven 30 kg seed bags were used. Treatments consisted of two factors: rotation speeds (null, 5, and 10 rpm) and feed flow rates (0.3, 0.6, and 1.2 Mg h-1), with three replicates. Soybean seeds of the CZ 37B51 IPRO cultivar (2022-2023 crop season) with 13% moisture content were used. The null speed resulted in the highest seed discards (up to 40%), especially at the highest feed flow rate. A speed of 5 rpm also resulted in high discards. A speed of 10 rpm with feed flows of 0.3 and 0.6 Mg h-1 resulted in better performance, reducing discard and improving the fraction of qualified seeds, although it may compromise the quality of these seeds. A speed of 10 rpm reduced the discard of high-quality seeds, and a flow of 1.2 Mg h-1 was less efficient, resulting in a higher discard of high-quality seeds compared to lower flows. densities separator 12 1 2 1. h1. h1 h Twentyseven Twenty seven 3 factors null, (null 0.3, 03 0 (0.3 06 6 h1, , h-1) replicates B 37B5 20222023 2022 2023 (2022-202 season 13 40%, 40 40% 40%) rate 0. h- performance highquality (0. 37B 2022202 202 (2022-20 4 (0 202220 20 (2022-2 ( 20222 (2022- (2022 (202 (20 (2

This study investigated the removal of contaminants in water by adsorption on thermoplastic starch (TPS) and kraft lignin (KL) composites. A study on the desorption of methylene blue (MB) and methyl orange (MO) dyes in water was also carried out, followed by the photodegradation of solutions containing dissolved dyes. Initially, the surface morphology of the TPS and TPS-KL films was analyzed by scanning electron microscopy, revealing advantageous characteristics for efficient adsorption of contaminants. Fourier transform infrared spectroscopy (FTIR) analysis made it possible to characterize the TPS and TPS-KL composites. The results demonstrate the reversibility of the process and confirm the lack of permanent chemical modification in the polymer matrix, indicating that the adsorption/desorption process is physical rather than chemical. This suggests that the adsorbent material can be reused without losing its fundamental structural properties. Furthermore, the study allows for verification of the chemical changes on the surfaces of the materials involved. Ultraviolet-visible spectroscopy (UV-Vis) results show that for MO, both substrates exhibited low adsorption capacity, with efficiency values close to 20%. In contrast, for MB, both composite materials displayed excellent dye adsorption rates, achieving efficiencies of 78% or higher. The photodegradation of adsorbed dyes revealed promising results.

Résumé L’augmentation de la participation des femmes en tant que représentantes élues à la législature rend plus fréquentes également les interactions entre législateurs - hommes et femmes - imprégnées de questions de genre. Selon certains sondages, même une fois élues, les femmes ont moins de capacité à exercer un pouvoir symbolique, étant limitées dans leur capacité à présenter et à diriger les agendas (setting agenda). De ce point de vue, nous avons observé les désaccords avec près de 70000 discours prononcés par des sénatrices et sénateurs brésiliens entre 1995 et 2018, pour analyser comment - et si - les dynamiques de genre se produisaient dans le cadre des discours, en mettant l’accent sur les interruptions. En fin de compte, nous avons conclu qu’au Sénat, le manterrupting n’avait pas lieu de manière générale. Les femmes, dans une large mesure, contrairement à ce qu’on peut lire dans la littérature, ne sont pas plus interrompues que les hommes. En même temps, nos conclusions montrent que les femmes leaders sont plus perturbées que les hommes leaders. De plus, surtout par des hommes appartenant au même parti. Cette donnée suggère que s’il existe des obstacles quant au pouvoir exercé par les femmes en plénière, elles se trouvent à l’intérieur de leurs partis.

Resumo O aumento da participação de mulheres como representantes eleitas para o Legislativo faz com que sejam mais frequentes também as interações entre legisladores – homens e mulheres – permeadas por questões de gênero. De acordo com algumas pesquisas, mesmo uma vez eleitas, mulheres detêm menos capacidade de exercer poder simbólico, sendo limitadas na sua capacidade de apresentar e liderar as agendas (agenda setting). A partir dessa perspectiva, observamos os apartes feitos a quase 70 mil discursos proferidos por senadores e senadoras brasileiros entre 1995 e 2018, para analisar como – e se – dinâmicas de gênero se davam no âmbito dos discursos, com foco nas interrupções. Ao final, concluímos que, no Senado, o manterrupting não acontecia de forma genérica. Mulheres, de forma ampla, diferentemente do que prevê parte da literatura, não são mais interrompidas que homens. Ao mesmo tempo, nossos achados mostram que mulheres líderes são mais interrompidas que homens líderes. Mais que isso: sobretudo por homens integrantes do mesmo partido.

Abstract The increased participation of women as elected representatives in Congress has brought gender issues to the forefront, which resulted in more frequent interactions between male and female legislators. According to some research, women still often face limitations in exerting power and agenda-setting. In order to explore this phenomenon, we analyzed approximately 70,000 speeches that Brazilian senators delivered between 1995 and 2018, with focus on gender dynamics within the speeches, particularly interruptions. Our findings indicate that manterrupting, or the act of men interrupting women, did not prevail in the Senate as a whole. Contrary to the predictions in existing literature, women were not interrupted more often than men in general. However, our research reveals that female leaders experience higher rates of interruption as compared to their male counterparts, mainly from male members within the same political party. These results suggest that barriers that hinder the influence of women in plenary sessions are likely rooted within their own parties. forefront legislators agendasetting. agendasetting agenda setting. setting agenda-setting phenomenon 70000 70 000 70,00 199 2018 interruptions manterrupting whole literature general However counterparts party parties 7000 7 00 70,0 19 201 700 0 70, 1 20 2

ABSTRACT Introduction/framework/objectives Salt production, especially using artisanal methods, does not exist in all countries, given the climatic and logistical requirements. Portugal has some tradition in this sector, but even so, most professionals working in Occupational Health and Safety have no experience in the area. The aim of this review was to summarize the most relevant and recent publications, to improve their performance capacity and enhance the productivity, satisfaction and well-being of the workers involved. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content Salt pans can be inland (far from the sea, using groundwater with a high salt content) or coastal. The former are scarcer in Portugal and only exist between Lisbon and Coimbra. Over time, in our country, evaporation was carried out by fire and sun. The latter is believed to have been developed by the Romans who created the first version of salt flats. At national level there is evidence of salt production since the end of the Neolithic, but here more frequently with the use of fire. Throughout Europe there has been a decline in artisanal versus industrial salt production, even in sea salt pans (especially on the northwest coast of France and, in Portugal, on the western coasts). Artisanal production in our country is more prevalent in the Figueira da Foz area. The product obtained via artisanal production has better quality, particularly in terms of flavor and nutritionally (via industrial production the taste is more metallic). Portugal is a large producer and consumer of traditional salt. The climatic characteristics suit production, due to summers with frequent high temperatures and strong, hot winds. National salt was and is consumed in other European countries; for presenting superior quality, even though it is more expensive. Production depends on the climate, namely insolation (number of hours in the sun), precipitation, temperature, cloudiness and winds (which affect evaporation). In other words, this is more intense and faster if the air temperature is higher, such as with more dry winds (which are generally more frequent in summer); low precipitation is also favorable. Salt production has been increasing, due to growing industrial needs. To be used in this last situation, it must be at 100% purity. Discussion and Conclusions No bibliography was found that referred the dimension of occupational health and safety in this professional sector. Based on the authors' theoretical and practical experience, the most relevant risk factors and risks in the sector are described: ultraviolet radiation and possible skin cancer, cataracts and other associated injuries; thermal discomfort and eventual higher accident rates associated with motor incoordination, worse cardiovascular adjustment, as well as disorientation and ability to make decisions; forced/maintained loads and/or postures and possible musculoskeletal injuries, emergence/worsening of hernia pathology and falling objects at the same level and possible bruises, skin lacerations and/or fractures. It would be interesting to learn more about the national panorama of this sector, through studies that hierarchically stratify the risk, also accurately describing occupational illnesses and associated accidents, as well as more effective measures to mitigate these issues.

RESUMO Introdução/enquadramento/objetivos A produção de sal, sobretudo com métodos artesanais, não existe em todos os países, dadas as exigências climáticas e logísticas. Portugal apresenta alguma tradição nesse setor mas, ainda assim, a maioria dos profissionais a exercer na Saúde e Segurança Ocupacionais não tem experiência na área. Pretendeu-se com esta revisão resumir o que mais relevante e recente se publicou, de forma a melhorar a capacidade de atuação destes e a potenciar a produtividade, satisfação e bem-estar dos trabalhadores afetos. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo As salinas podem ser interiores (afastadas do mar, usando água subterrânea com elevado conteúdo em sal) ou litorais. As primeiras são mais escassas em Portugal e apenas existem entre Lisboa e Coimbra. Ao longo do tempo, no nosso país, a evaporação era realizada pelo fogo e sol. Esta última acredita-se que foi desenvolvida pelos romanos que, de certa forma, criaram a primeira versão das salinas. A nível nacional há evidência de produção de sal desde o final do Neolítico, mas aqui mais frequente com a utilização do fogo. Por toda a Europa tem existido um declínio da produção artesanal de sal, versus industrial, mesmo em salinas marítimas (sobretudo na costa noroeste de França e, em Portugal, na costa ocidental). A produção artesanal no nosso país é mais prevalente na zona da Figueira da Foz. O produto obtido via artesanal tem mais qualidade, nomeadamente a nível de sabor e nutricionalmente (via industrial o paladar é um pouco mais metálico). Portugal é um grande produtor e consumidor de sal tradicional. As caraterísticas climáticas adequam-se à produção, devido aos verões com temperaturas elevadas frequentes e ventos fortes e quentes. O sal nacional era e é consumido noutros países europeus, por apresentar qualidade superior, mesmo tendo um preço mais elevado. A produção depende do clima, nomeadamente a insolação (número de horas ao sol), precipitação, temperatura, nebulosidade e ventos (que condicionam a evaporação). Ou seja, esta é mais intensa e rápida se a temperatura do ar for mais elevada, tal como com mais ventos secos (que geralmente são mais frequentes no Verão); a baixa precipitação também é favorável. A produção de sal tem vindo a aumentar, até pelas crescentes necessidades industriais. Para ser usado nesta última situação, deverá estar no patamar de 100% de pureza. Discussão e Conclusões Não se encontrou bibliografia que fizesse referência à dimensão da saúde e segurança ocupacionais neste setor profissional. Em função de experiência teórica e prática dos autores, descrevem-se os fatores de riscos e riscos mais relevantes do setor: radiação ultravioleta e eventual cancro de pele, cataratas e outras lesões associadas; desconforto térmico e eventual maior sinistralidade associada a descoordenação motora, pior ajuste cardiovascular, bem como desorientação e capacidade de tomar decisões; cargas e/ou posturas forçadas/mantidas e eventuais lesões músculo-esqueléticas, surgimento/agravamento de patologia herniária e queda de objetos e ao mesmo nível e eventuais equimoses, lacerações cutâneas e/ou fraturas. Seria interessante conhecer melhor o panorama nacional deste setor, através de estudos que estratificassem hierarquicamente o risco, descrevendo ainda com rigor as doenças profissionais e acidentes associados, bem como medidas mais eficazes para atenuar essas questões.

Abstract Introduction: The limited availability of data in Chile on the use of diagnostic images (DI) poses a challenge in the efficient management of resources. Objective: To quantify and characterize the use of DI in hospitalized subjects in Chile for 1 year. Method: Descriptive population based study on the use of DI in Chile during 2019 in hospitalized subjects using an official national database recorded with the diagnosis-related groups (DRG) system. Demographic variables related to hospitalization and derived from the DRG were analyzed. Results: 55.5% of hospital events involved at least one DI (n = 466,306). The most used imaging technique was radiography/X-ray (36.4%), followed by computed tomography (35%). The Magallanes and Aysén regions exhibited the highest DI rates. Hospitalized patients who required some DI had an average of days of hospitalization and mortality rate that were 3.4 and 5.5 times greater than those who did not require DI (p < 0.01). Conclusions: There are important geographical differences in the use of DI in Chile. Our description will facilitate future studies that delve deeper and explore access or socioeconomic differences.

Objetivo: Cuantificar y caracterizar el uso de ID en sujetos hospitalizados en Chile durante 1 año. Método: Estudio poblacional descriptivo sobre el uso de ID en Chile durante el año 2019 en sujetos hospitalizados utilizando una base de datos nacional oficial consignada con la herramienta de grupos relacionados a diagnósticos (GRD). Se analizaron variables demográficas, relativas a la hospitalización y derivadas de los GRD. Resultados: El 55,5% de los eventos hospitalarios involucró al menos una ID (n = 466.306). La modalidad de imagen más utilizada fue la radiografía (36,4%), seguida por la tomografía computada (35%). Las regiones de Magallanes y Aysén exhibieron las tasas de ID más altas. Los pacientes hospitalizados que requirieron alguna ID obtuvieron unos promedios de días de hospitalización y letalidad 3,4 y 5,5 veces mayores que los que no requirieron ID (p < 0,01). Conclusiones: Existen importantes diferencias geográficas en la utilización de ID en Chile. Nuestra descripción facilitará la realización de futuros estudios que profundicen y exploren las diferencias en el acceso o socioeconómicas.

ABSTRACT Ginger (Zingiber officinale Roscoe) waste is a residue from industrial factories that has potential for utilization in the production of bio-extract for pest control. Therefore, this study aimed to investigate the toxicity of fermented ginger waste extract through contact toxicity and oral toxicity methods in controlling the common cutworm (Spodoptera litura Fabricius) and the beet armyworm (Spodoptera exigua Hübner). The experiment was a completely randomized design (CRD) with 10 replicates. Mortality rates were recorded at 48, 72, and 96 h after treatment under laboratory conditions. Fermented ginger waste extract at concentrations of 0%, 5%, 25%, 50%, and 100% (w/v) was used. The results showed that for the contact toxicity method at 100% concentration after 96 h, the common cutworm had the highest mortality rate of 76.00 ± 1.29% (LC50 = 14.450 μg larva-1), while the beet armyworm had the highest mortality rate of 66.00 ± 0.95% (LC50 = 68.426 μg larva-1). For the oral toxicity method, the common cutworm had the highest mortality rate of 52.00 ± 1.70% at 100% concentration after 96 h (LC50 = 91.275 μg larva-1), and the beet armyworm had the highest mortality rate of 58.00 ± 1.02% at 100% concentration after 96 h (LC50 = 88.400 μg larva-1). Therefore, the results of this study demonstrate the efficacy of fermented ginger waste extract in controlling common cutworm and beet armyworm under laboratory conditions, and it has the potential for further application in field conditions.
