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 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.

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.

Acetic acid bacteria (AAB) are versatile organisms that catalyze the conversion of a wide range of carbon sources into biomolecules of great industrial interest. In this study, we exploited the ability of Gluconobacter spp. to synthesize levans. Among the isolated strains, Gluconobacter cerinus UELBM11 produced approximately 14.0 g L−1 of levan under non-optimized conditions. Gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FTIR), and nuclear magnetic resonance (NMR) analyses confirmed that levan obtained from G. cerinus UELBM11 consisted of a β-(2→6)-D-fructose backbone with some β-(2→1) ramifications. The average molecular weight (Mw) of the purified levan was 8.78 × 105 Da. Thermogravimetric/differential thermogravimetric (TGA/DTG) analysis indicated high thermal stability, with the maximum decomposition rate observed at 227.44 °C. Scanning electron microscopy (SEM) revealed a microporous morphology, and the antioxidant activity assays demonstrated that levan had a high scavenging capacity of 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and hydroxyl radicals. Therefore, it has been demonstrated the levan produced by G. cerinus UELBM11 is a promising natural antioxidant and, owing to its microporosity and excellent thermal properties and stability, is a potential candidate as an additive in cosmetics, pharmaceuticals, and food products.

Novel nanocomposites synthesized with pollen grain, as a precursor, were tested for CO2 adsorption performance. The pollen-derived carbons were obtained by direct calcination (PC), calcination followed by KOH-chemical activation (PCKOH), and MgO incorporation using high-energy ball-milling (PC-MgO and PCKOH-MgO). All the as-prepared materials were texturally, morphologically and structurally characterized by N2 physisorption, scanning electron microscopy (SEM-EDS) and X-ray diffraction (XRD); CO2 adsorption/desorption was measured by thermogravimetry. The four materials were able to adsorb CO2 at 30 ºC and 1 bar, but PCKOH-MgO, with the high surface area (12.4 m2 g-1), total pore volume of (0.13 cm3 g-1) and microporosity, was the best (2.06 mmol g-1 and percentage of adsorption (Qad) = 9.06%, at 1 bar). This result is due to the synergic effect of both synthesis methods. Neither temperature (from 30 to 100 ºC), nor pressure (from 1 to 15 bar), improved the adsorption process of PCKOH-MgO. CO2 desorption times at 300 ºC were 47 min for PCKOH-MgO and 30 min for the other adsorbents, showing the possibility of cycling. Based on the obtained results, the PCKOH-MgO activated carbon nanocomposite stands as a promising adsorbent to be potentially used for industrial CO2 capture applications and to contribute to long-term solutions to avoid dangerous climate-change and reduce CO2 emissions. grain precursor CO performance pollenderived derived PC, PC , (PC) KOHchemical KOH chemical PCKOH, PCKOH (PCKOH) highenergy energy ballmilling ball milling PCMgO PCKOHMgO.

Abstract The Marabá Industrial District (MID) is a place connected with the transformation and processing of resources from the perspective of adding value to the iron ore of Carajás (State of Pará). However, local industries have promoted a great spatial transformation, using archaic and polluting techniques and technologies. After an increase in costs and changes in international prices, the areas of these industries were abandoned, indicating a brownfield process under formation in the MID and related areas. This was followed by a process of transhumance, accompanied by cycles of economic contraction and concentration. A mining-industrial periphery condition is perceived in the implementation and conception of the MID, as well as its formation as a brownfield, with spatial, economic, demographic, and environmental repercussions.

RESUMO A densidade de plantas e o espaçamento correto são fatores fundamentais para alcançar produtividade rentável e qualidade dos frutos em culturas agrícolas. Este estudo teve como objetivo avaliar a produtividade do tomateiro de crescimento determinado e as características físico-químicas dos frutos, em diferentes arranjos de plantio e densidades de plantas. Foram realizados dois experimentos, sendo que no primeiro experimento e no segundo experimento foram utilizados os híbridos CVR-2909 (CVR Plant Breeding) e HMX 7885 (Agristar), respectivamente. Os experimentos foram conduzidos em delineamento de blocos casualizados, com quatro repetições. Foram avaliados dez tratamentos em esquema fatorial duplo (2 × 5). No primeiro fator, foram avaliados dois arranjos de plantio: linhas simples e linhas duplas. No segundo fator, foram avaliadas cinco densidades de plantas: 15, 20, 25, 30 e 35 mil plantas ha-1. Para o híbrido CVR-2909, o cultivo em linhas simples proporcionou maior produtividade, já as maiores densidades de plantas resultaram em menor produção e número de frutos por planta. Para o híbrido HMX-7885, maiores densidades de plantas proporcionaram maior produtividade, porém com menor produção por planta, massa média e número de frutos por planta.

ABSTRACT Plant density and correct row spacing are fundamental factors for achieving profitable yield and fruit quality in crops. This study aimed to evaluate the yield of tomato plants of determinate growth and the physicochemical characteristics of the fruits in different planting arrangements and plant densities. Two experiments were conducted using the hybrids CVR-2909 (CVR Plant Breeding) and HMX 7885 (Agristar) in the first and second experiments, respectively. The experiments were conducted in a randomized block design with four replicates. Ten treatments were evaluated in a double factorial scheme (2 × 5). Two planting arrangements were evaluated in the first factor: single and double rows. The second factor comprised five plant densities: 15, 20, 25, 30, and 35 thousand plants ha-1. For the CVR-2909 hybrid, single-row cultivation resulted in the highest yield, while higher planting densities gave the lowest yield and number of fruits per plant. For the HMX-7885 hybrid, it was found that higher densities gave higher yields but caused a decreasing effect on fruit production per plant, average fruit mass, and number of fruits per plant. For this hybrid, the planting arrangement provided a higher rate of green fruits. crops CVR2909 CVR 2909 CVR-290 Breeding 788 Agristar (Agristar respectively replicates 2 ( 5. 5 . 5) rows 15 20 25 30 3 ha1. ha1 ha 1. 1 ha-1 hybrid singlerow HMX7885 HMX-788 mass CVR290 290 CVR-29 78 ha- HMX788 HMX-78 CVR29 29 CVR-2 7 HMX78 HMX-7 CVR2 CVR- HMX7 HMX-

The present work aims to extract and test cashew nut peel oil as a natural antioxidant in the oxidative stabilization of biodiesel. Therefore, determinations of the ideal time of Soxhlet and thermal extractions, Fourier transform infrared spectroscopy (FTIR) analyses, and evaluation of the oxidative stability by Rancimat method were carried out. FTIR analyses revealed that the 3rd cycle of extraction was sufficient to extract all the oil, with an average yield of 30.0%. For the thermal extraction of the laboratory technical cashew nut peel oil, the best extraction, based on statistical analysis, was 60 min, yielding 20.0%. The FTIR analysis of the extracted cashew nut peel oil showed characteristic peaks of phenolic groups and organic acids, showing differences in the intensities of the absorption bands. The oxidative stability showed induction period of 8 h 40 min for the hydraulic press extraction, 10 h 35 min for the Soxhlet extraction, and 10 h 65 min for the industrial technical extraction of the cashew nut peel oil. All values were below the 12-h limit established by the National Agency for Petroleum, Natural Gas and Biofuels (ANP). The technical cashew nut peel oil extracted in the laboratory presented an induction period of 11 h 12 min, close to that recommended by ANP, proving to be a promising natural antioxidant. Cardanol presented satisfactory results with 25 h 22 min, double that suggested by ANP. Thus, cashew nut peel oil showed important and promising results as a natural antioxidant for biodiesel. biodiesel Therefore extractions (FTIR out rd 300 30 0 30.0% 6 200 20 20.0% acids bands 4 1 3 12h Petroleum ANP .

Brazilian Savanna biodiversity is abundant in native fruits with nutritional and sensory properties with potential technological applications. However, the information available regarding the proprieties of Brazilian native fruits is still limited. This study aimed to analyze the metabolic profile of Brosimum gaudichaudii fruits (BGF) using metabolomics approaches, besides its physicochemical and nutritional proprieties. BGF exhibited protein content at least two times higher than other native fruits. Fifty-five metabolites were identified by the metabolomics approaches, mainly fatty acids (n = 22), carbohydrates (n = 13), organic acids (n = 6), and polyphenols (n = 5). The most abundant constituents were D-fructose (42.97%) for sugars, L-asparagine (6.47%) for amino acids, succinic acid (44.11%) for organic acids, and linolenic acid (3.04%) for fatty acids. Highlighted phytochemicals included chlorogenic acid, α-amyrin, and γ-tocopherol. Additionally, this study revealed that BGF is a good source of vitamin C and dietary fiber and an excellent source of vitamin A. Future studies providing nutritional information and suggesting consumption methods and potential industrial applications are essential to familiarize consumers with these foods. Additionally, clarifying the appropriate planting and harvesting seasons can revive traditional practices, especially for native fruits like BGF.

Brazil is home to a rich biodiversity of native edible fruits renowned for their health-promoting compounds and flavors. Among these, Eugenia uniflora L. (Brazilian pitanga) is particularly notable. The fruit varies in color from yellow to purple and is prized for its intense aroma and versatile taste profile. However, information about the compounds responsible for their nutritional and sensory potential is still limited. This study analyzed volatile compounds and metabolites in yellow, red and purple pitanga fruits (Eugenia uniflora) at various ripening stages, exploiting a metabolomics approach. Yellow pitanga had 30 volatile compounds, with esters (40%), terpenes (26.67%) and aldehydes (16.67%) constituting 83.34% of identified volatile compounds. Red pitanga featured 26 volatile compounds, primarily terpenes and esters (each 30.77%) and aldehydes (15.38%), making up 76.92%. Purple pitanga contained 39 volatile compounds, with terpenes and esters (each 35.90%) and aldehydes (17.95%), totaling 89.75% of identified volatile compounds. Across all pitanga types, 124 metabolites were identified, including saturated fatty acids (17.74%), terpenes (17.74%) and sugars (16.93%), constituting 52.41% of identified metabolites. Future studies should provide nutritional information, consumption methods and industrial applications for pitanga fruits, focusing on sensory analysis, health benefits, preservation and breeding to enhance bioactive compounds and flavor. healthpromoting promoting flavors these L Brazilian notable profile However limited stages approach 3 40%, 40 40% , (40%) 26.67% 2667 67 (26.67% 16.67% 1667 16 (16.67% 8334 83 34 83.34 2 each 30.77% 3077 77 15.38%, 1538 15.38% 15 38 (15.38%) 7692 76 92 76.92% 35.90% 3590 35 90 17.95%, 1795 17.95% 17 95 (17.95%) 8975 89 75 89.75 types 12 17.74%, 1774 17.74% 74 (17.74% 16.93%, 1693 16.93% 93 (16.93%) 5241 52 41 52.41 analysis benefits flavor 4 (40% 26.67 266 6 (26.67 16.67 166 1 (16.67 833 8 83.3 30.77 307 7 153 15.38 (15.38% 769 9 76.92 35.90 359 179 17.95 (17.95% 897 89.7 177 17.74 (17.74 169 16.93 (16.93% 524 5 52.4 (40 26.6 (26.6 16.6 (16.6 83. 30.7 15.3 (15.38 76.9 35.9 17.9 (17.95 89. 17.7 (17.7 16.9 (16.93 52.

ABSTRACT Adequate seed placement is essential for consistent crop emergence and initial growth. Pneumatic seed metering systems offer superior longitudinal seed distribution accuracy compared to traditional methods, yet certain factors can influence this precision. For instance, seed physical properties may be altered by phytosanitary treatments applied either on-farm or industrially. This study examined the effects of phytosanitary treatment type and graphite addition on soybean seed deposition using an electric-driven pneumatic feeder under simulated sowing conditions. Seed distribution was monitored with an optical sensor. Four treatment groups were established: untreated without graphite, untreated with graphite added, on-farm treated with graphite, and industrially treated with graphite. Parameters assessed included average spacing between seeds, coefficient of variation, precision index, multiple and failed spacings, and percentage of acceptable spacing. Results indicate that prior seed treatment does not significantly affect overall planting accuracy. However, seed spacing varied between the untreated and on-farm treated groups, with the latter demonstrating closer proximity to optimal values. Both on-farm and industrial treatments yielded more uniform seed deposition, as indicated by a lower coefficient of variation. Regardless of seed treatment, the pneumatic feeder consistently performed effectively. growth methods instance onfarm farm electricdriven electric driven conditions sensor established added seeds variation index spacings However values effectively

RESUMO A deposição adequada de sementes tem grande importância na uniformidade da emergência e no desenvolvimento inicial das culturas. Uma maior precisão na distribuição longitudinal de sementes é possível com mecanismos dosadores de sementes pneumáticos em relação aos convencionais, mas existem alguns aspectos que afetam essa precisão. Por exemplo, a qualidade física das sementes pode ser impactada pelo seu tratamento fitossanitário, que pode ser feito na propriedade ou na indústria. Nesse contexto, este estudo investigou o impacto do tipo de tratamento fitossanitário e do uso de grafite na deposição de sementes de soja por meio de dosador pneumático com acionamento elétrico em bancada estática, simulando a semeadura e monitorando a distribuição das sementes com sensor óptico. As sementes foram submetidas a quatro tratamentos distintos: sem grafite, sem tratamento com adição de grafite, tratamento on-farm com adição de grafite e tratamento industrial com adição de grafite. Foram estudados o espaçamento médio entre deposições, coeficiente de variação de semeadura, índice de precisão, espaçamentos múltiplos e falhas e percentual de espaçamento aceitável. Os resultados indicam que o espaçamento adequado no plantio não é significativamente impactado pelo método de tratamento prévio das sementes. O espaçamento entre sementes diferiu entre os tratamentos sem grafite e pelo tratamento on-farm, sendo este último mais próximo do ótimo e o tratamento sem grafite mais distante do espaçamento ideal. Um coeficiente de variação de semeadura mais baixo indica que a deposição uniforme foi alcançada com os procedimentos on-farm e industriais. Independentemente do tratamento de sementes, o dosador pneumático demonstrou eficácia. culturas convencionais exemplo indústria contexto estática óptico distintos onfarm on farm deposições aceitável onfarm, farm, ideal industriais eficácia

ABSTRACT: To improve the nutritional and functional quality of agro-industrial waste, his study established a ternary mixture of flours made from pineapple, acerola, and passion fruit waste using the simplex-centroid design, as well as to evaluate their effects on the physicochemical and sensory characteristics of edible ice cream. Using mixture planning, nine ternary flour components were applied to edible ice cream formulations to evaluate acceptance scores for taste, texture, and overall impression attributes, as well as physicochemical parameters (pH, acidity, soluble solids, and color parameters) and microbiological parameters (thermotolerant coliforms at 45 ºC, Enterobacteriaceae and Salmonella). The simplex-centroid design demonstrated that the cubic model best predicts the results for the analyzed sensory attributes. The response surface graphs indicated the area of greatest acceptance in the formulations with the maximum percentage established for the flour with acerola waste. The highest level of acceptability was given to the ternary mixture of 60%, 30%, and 10% pineapple, passion fruit, and acerola flours, respectively. The results indicated that sorbet enriched with flour composed of the ternary mixture is a product with the potential for exploitation, as well as contributing to the reduction of environmental impacts generated by the large and improper disposal of agro-industrial fruit processing residues in the ecosystem.

RESUMO: Visando a qualidade nutricional e funcional dos resíduos agroindustriais, o estudo teve como objetivo estabelecer a mistura ternária de farinhas elaboradas com resíduos de abacaxi, acerola e maracujá utilizando o delineamento simplex-centroide, assim como avaliar seus efeitos nas características físico-químicas e sensoriais em gelados comestíveis. Com o planejamento de misturas, nove componentes ternários das farinhas foram aplicados em formulações de gelados comestíveis para avaliação dos escores de aceitação para os atributos sabor, textura e impressão global, bem como os parâmetros físico-químicos (pH, acidez, sólidos solúveis e parâmetros de cor) e microbiológicos (coliformes termotolerantes a 45 ºC, Enterobacteriaceae e Salmonella). O delineamento simplex-centroide demonstrou que o modelo cúbico melhor prediz os resultados para os atributos sensoriais analisados. Os gráficos de superfície de resposta indicaram a área de maior aceitação nas formulações com o máximo percentual estabelecido para a farinha com os resíduos de acerola. O maior índice de aceitabilidade foi atribuído a mistura ternária constituída com 60%, 30% e 10% para as farinhas de abacaxi, maracujá e acerola, respectivamente. Os resultados indicaram que o sorbet enriquecido com a farinha composta pela mistura ternária é um produto com potencial para exploração, além de contribuir para a redução dos impactos ambientais gerados pelo grande e inadequado descarte de resíduos do processamento agroindustrial de frutas no ecossistema.
