The species Oryza sativa (rice) and Musa cavendishii (banana) are sources of cellulose-rich waste biomass in the Amazon region, Tocantins State. This research investigates the nanoscale production of cellulose through the interactions between three choline amino acid ionic liquids Ch[AA]IL and the respective fibers by pretreatment. To this end, the synthesis of three ILs was carried out: choline arginate Ch[Arg], choline glycinate Ch[Gly] and choline lysinate Ch[Lys], characterized by Fourier transform infrared spectroscopy (FTIR). The samples resulting from the pretreatment were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). It was possible to infer from the SEM micrographs that Ch[Arg] caused greater fiber breakage than the other ILs. The TEM analyses identified fibers up to 16 nm in diameter. Positive effects were observed in the diffractograms, although no crystallinity was obtained in the pretreated samples. Thermogravimetry curves showed that the fibers treated with Ch[Arg] showed higher thermal stability. rice (rice banana (banana celluloserich rich region State ChAAIL Ch AA IL end out ChArg, ChArg Arg , ChGly Gly Ch[Gly ChLys, ChLys Lys Ch[Lys] FTIR.

RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

ABSTRACT Proper waste management is a major worldwide concern; waste is disposed of directly into the environment, affecting water, soil and air quality. The development and production of green energy sources is strongly encouraged in modern society. The aim of this study, in accordance with Sustainable Development Goals (SDGs) 1, 2 and 7 of the 2030 Agenda of the UN, is to combine the correct disposal of animal waste with the generation of energy to mitigate the energy insecurity of families in an extremely vulnerable semi-arid region in the north-east of the country using biodigesters. To this end, a conceptual proposal was drawn up for a low-cost, easy-to-maintain and easy-to-use biodigester. A small-scale prototype was used to assess its operation by evaluating the main factors that affect biogas production (pH, temperature and the biomass properties: total solids, fixed solids, volatile solids, concentration of volatile fatty acids and C/N ratio). Evaluation of the test prototype gave satisfactory results that corroborate other studies and make it possible to propose an economically viable and efficient full-scale biodigester for biogas production. concern environment water quality society study SDGs (SDGs 1 203 UN semiarid semi arid northeast north east biodigesters end lowcost, lowcost low cost, cost low-cost easytomaintain easy maintain easytouse use smallscale small scale pH, pH (pH properties solids CN C N ratio. ratio . ratio) fullscale full 20

This paper presents the stages of an acceleration program focused on chemical technologies. We demonstrate how this initiative contributes to the creation of new businesses, startups, and technology licensing from research developed at Brazilian universities. The case of the program Escale-se is discussed. There were 66 technologies submitted, and 14 were selected for the pre-acceleration phase. In this phase, various contents were worked on, such as creating a business model and aspects of scaling hard-science technologies. Teams were evaluated by panels with market specialists, and 6 were selected for the second phase: pre-scaling/proof of concept. Here, proponents were encouraged to validate the business model by connecting with potential clients and partners, as well as planning the development and testing of the product in a relevant environment. Finally, one team was classified for the last stage: scaling/go-to-market - where they received R$ 100,000.00 to scale up their technology and create strategies for raising investments. Four of the fourteen technologies selected for the program opened National Register of Legal Entities (CNPJ) and raised approximately R$ 4.5 M in investments from different sources. These results demonstrate that the methodology contributed to the entrepreneurial development of participating researchers and the raising of funds for the businesses created. startups universities Escalese Escale se discussed submitted 1 preacceleration pre phase hardscience hard science specialists prescaling/proof prescalingproof scaling/proof proof concept Here partners environment Finally stage scaling/gotomarket scalinggotomarket scaling/go go R 10000000 100 000 00 100,000.0 CNPJ (CNPJ 45 4 5 4. sources created prescaling scalingproof gotomarket scalinggo 1000000 10 0 100,000. 100000 100,000 10000 100,00 1000 100,0 100,

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.

RESUMO A estruvita (NH4MgPO4∙6H2O) é um fertilizante de liberação lenta obtido através da recuperação de fósforo e/ou nitrogênio de águas residuais geralmente pela adição de sais de magnésio. Neste sentido, objetivou-se avaliar a viabilidade da substituição de fontes comerciais de magnésio por fontes alternativas no processo de precipitação de estruvita, em termos de remoção de amônio e fosfato, e quantificação e caracterização do cristal precipitado. Os experimentos foram conduzidos em escala de bancada sob delineamento inteiramente casualizado a pH 9,5 através da precipitação de uma solução de efluente sintético com quatro diferentes fontes de magnésio: MgCl2∙6H2O, MgSO4∙7H2O, MgO e magnesita (MgCO3). Após pré-acidificação, soluções derivadas de fontes alternativas de baixo custo de magnésio removeram acima de 55 e 90% de nitrogênio amoniacal e fosfato em solução, respectivamente, e alcançaram por volta de 10 g L-1 de cristais precipitados. A proximidade dos resultados obtidos com soluções derivadas de fontes comerciais de magnésio (46ꟷ56% de remoção de nitrogênio amoniacal, 97% de remoção de fosfato, e mais de 6 g L-1 de precipitado formado) indicou que reagentes alternativos puderam facilmente substituir os comerciais se submetidos ao prévio processo de digestão, a fim de tornar o magnésio disponível em solução. A análise qualitativa por difratometria de raios-X confirmou a presença de estruvita e newberyita na maioria dos precipitados.

ABSTRACT Struvite (NH4MgPO4∙6H2O) is a slow-release fertilizer obtained through phosphorus and/or nitrogen recovery from wastewaters, usually by adding magnesium salts. In this sense, the aim was to evaluate the viability of replacing commercial magnesium sources with alternative ones in the struvite precipitation process regarding ammonium and phosphate removal and precipitated crystal quantification and characterization. Experiments were conducted on a bench scale in a completely randomized design at pH 9.5 by precipitation of synthetic wastewater solution with four magnesium sources: MgCl2∙6H2O, MgSO4∙7H2O, MgO, and magnesite (MgCO3). After pre-acidification, derived solutions from low-cost alternative sources of magnesium removed above 55 and 90% of ammonium nitrogen and phosphate in solution, respectively, and reached around 10 g L-1 of precipitated crystals. Results proximity obtained with solutions derived from commercial sources of magnesium (46ꟷ56% of ammonium nitrogen removal, 97% of phosphate removal, and more than 6 g L-1 of precipitate formed) indicated that alternative reagents could easily substitute commercial ones if submitted to the previous digestion process, making magnesium available in solution. Qualitative analysis by X-ray diffraction confirmed the presence of both struvite and newberyite in most precipitates.

Bulk precipitation (BP) samples were collected at two coastal urban sites and two montane Atlantic Forest (400 and 1000 m altitude) areas in southeastern Brazil from August 2008 to August 2009. These samples were analyzed for the major inorganic ions (H+, Na+, K+, Ca2+, Mg2+, Cl- and SO42-) found in rainwater. The concentrations of inorganic nitrogen species (NH4+, NO3- and NO2-) were compiled from a previous study. The volume-weighted mean (VWM) concentrations of inorganic ions differed spatially, with higher values at the coastal urban and coastal periurban sites. On a molar basis, Cl- and Na+ together comprised 60% of the total inorganic constituents at the coastal urban site and 34-42% at the other three sites, as it is the closest to the ocean. Magnesium was also primarily associated with sea-salt aerosol. Non-sea-salt (nss) fractions of K+, Ca2+ and SO42- comprised 68-93% of their VWM concentrations, indicating the contribution of natural (mostly biogenic) and anthropogenic (SO2 oxidation for the latter) sources. Finally, we found that the acidity of BP at the four sampling sites is primarily controlled by the NH4+, nss-Ca2+, nss-SO42-, and NO3- ions, resulting in VWM pH values ranging from 5.60 (lower montane forest) to 5.98 (coastal periurban site).

This study highlights the synthesis of innovative polyurethane materials derived from Moringa oleifera oils extracted from two distinct sources. The oils were converted into their respective polyols through the in situ generated performic acid method. Diverse material characteristics were observed due to different agroclimatic and cultivation conditions for the sources. Extraction yields were 45.21% (source 1) and 40.32% (source 2), with acid values of 28.70 and 26.00 mg KOH per g of oil, respectively. Oleic acid constituted 79.87 and 67.11% of the oils composition, respectively. Nuclear magnetic resonance and Fourier transform infrared spectroscopy (FTIR) confirmed the hydroxylation of the oils. FTIR also identified the isocyanate structures in the synthesized polyurethane materials. Gel permeation chromatography analysis revealed a higher oligomer content in the polyol synthesized from the oil extracted from source 2. Thermogravimetric analysis demonstrated enhanced thermal stability post-oil conversion, highlighting decomposition stages for rigid and flexible segments. Differential scanning calorimetry indicated higher unsaturation in the oil extracted from source 1, resulting in an elevated crystallization temperature. Tensile testing showed increased elasticity as the [NCO]/[OH] ratio decreased in the material, emphasizing the influence of polyol and crosslinking agent concentrations on mechanical resistance of polyurethane materials. sources method 4521 45 21 45.21 1 4032 40 32 40.32 2, 2 , 2) 2870 28 70 28.7 2600 26 00 26.0 respectively 7987 79 87 79.8 6711 67 11 67.11 composition (FTIR postoil post conversion segments temperature NCO/OH NCOOH NCO / OH [NCO]/[OH 452 4 45.2 403 3 40.3 287 7 28. 260 0 26. 798 8 79. 671 6 67.1 45. 40. 67.

ABSTRACT The search for more sustainable systems of rice cultivation, especially in relation to water use, has included the evaluation of more-efficient irrigation systems in addition to alternative water sources. The aim of this study was to conduct a phytosociological survey of weeds in rice crops irrigated by subsurface drip with different concentrations of treated dairy effluent, maintaining the soil moisture at saturation or field capacity. A pilot scale experiment was carried out in a protected environment using a randomised block design in a 5 x 2 factorial scheme, with four replications. The IAC 301 cultivar (Arborio rice) was chosen. The phytosociological surveys were carried out on four different dates, and considered the composition as well as the distribution of plant species in each of the applied treatments, using the importance value index (IVI) to evaluate the influence of each treatment. The results showed that cultivating irrigated rice, giving priority to water management, altered the ecology of invasive plants. Fourteen weed species were identified, distributed over 10 families. The effluent dose did not alter the incidence of invasive plants, and only at the final evaluation was there a reduction in the IVI value at effluent concentrations of 50% and 75%. For soil moisture, the highest IVI values occurred on the first two days of the survey under saturated conditions; this result was reversed closer to plant maturity, when the IVI values were higher at field capacity. cultivation use moreefficient efficient sources capacity scheme replications 30 Arborio chosen dates treatments (IVI treatment management plants identified 1 families 50 75 75% conditions maturity 3 7

The strategic levers of control can now be treated by organizations as possible sources of dynamic capabilities. entrepreneurship dynamism resources management learning planning related employees survey modelling method hypothesis opportunities

RESUMO: O melão de polpa alaranjada honeydew apresenta elevado potencial nutricional e econômico, sendo amplamente apreciado como fruta doce e refrescante. Portanto, avaliar amostras comerciais de produtos tão relevantes para o mercado de frutas frescas é de grande importância. O objetivo deste estudo foi investigar a capacidade antioxidante, os parâmetros de qualidade e a composição química de melões do mercado brasileiro. Os valores de pH e ºBrix determinados para as amostras de melão foram 6,5 ± 0,30 e 9,2 ± 0,80 g/100 g (peso fresco), respectivamente, o que está de acordo com os resultados esperados para melões de alta qualidade. A análise cromatográfica revelou a sacarose (49% do açúcar total) como principal açúcar, seguida pela frutose (30%) e glicose (21%). Os carotenóides, que estão diretamente ligados à cor laranja característica, apresentaram teor total de 270,59 µg/g (peso seco). Além disso, o maior valor de b* comparado ao valor de a* indica a maior contribuição da cor amarela. Quanto ao potencial antioxidante, além de apresentar capacidade antioxidante para ambos os métodos aplicados, DPPH e FRAP, níveis variando de 16,40 ± 0,21 µmol equivalente de ácido ascórbico/g a 56,98 ± 0,80 µmol equivalente de Trolox/g (peso seco) foram encontrados nos extratos de melão. Ademais, os resultados foram maiores em termos de FRAP do que em DPPH. Desta forma, os resultados destacam os melões avaliados como fontes valiosas de compostos bioativos, como carotenóides e fenólicos, que contribuem para suas propriedades antioxidantes. Além disso, análises de cor, pH e teor de sólidos solúveis totais também refletem os atributos de qualidade.

ABSTRACT: Orange-fleshed non-netted honeydew melon has high nutritional and economic potential, being widely appreciated as a refreshing sweet fruit. Therefore, evaluating commercial samples of such relevant products for the fresh fruit market is of great importance. This study investigated the antioxidant capacity, quality parameters, and chemical composition of honeydew melons from the Brazilian market. The values of pH and °Brix determined for melon samples were 6.5 ± 0.30 and 9.2 ± 0.80 g/100 g (fresh weight), respectively, which agree with the results expected for high-quality melons. The chromatography analysis revealed sucrose (49% of total sugar) as the main sugar, followed by fructose (30%) and glucose (21%). Carotenoids, which are directly linked to the characteristic orange color, showed a total level of 270.59 µg/g (dry weight). Additionally, the higher b* value compared to a* value indicates the highest yellow contribution. Regarding the antioxidant assays, in addition to presenting antioxidant capacity for both methods applied, DPPH and FRAP, levels ranging from 16.40 ± 0.21 µmol ascorbic acid equivalent/g to 56.98 ± 0.80 µmol Trolox equivalent/g (dry weight) were reported in melon extracts. Moreover, the results were higher in terms of FRAP than DPPH. Therefore, the results underscore the evaluated honeydew melons as valuable sources of bioactive compounds, such as carotenoids and phenolics, which contribute to their antioxidant properties. Besides, analyses of color, pH, and total soluble solids content also reflect the quality attributes.

RESUMO A solução fundamental para o problema do entupimento do emissor é explorar o projeto ideal da estrutura do emissor e melhorar sua capacidade anti-entupimento. O objetivo da pesquisa foi selecionar a forma estrutural ideal do caminho de fluxo do emissor em sistemas de irrigação por gotejamento utilizando fontes de água de qualidade inferior, proporcionando suporte teórico para melhorar a capacidade anti-obstrução do próprio emissor e para o projeto de novos produtos de emissores. A seleção da estrutura do caminho do fluxo do emissor não tem sido conduzida com base na determinação do modelo de simulação apropriado com a condição complexa de qualidade da água. Para tanto, determinou-se o modelo de movimento interno do fluido adequado do emissor, e avaliou-se de forma abrangente o desempenho hidráulico e o desempenho anti-entupimento das cinco estruturas representativas da trajetória de fluxo no país e no exterior, e finalmente determinou-se a estrutura ótima da trajetória de fluxo do emissor. Os resultados da pesquisa indicaram que o modelo RNG k-ε foi o mais adequado para simular a área do fluxo no emissor por meio da análise abrangente da lacuna entre os valores simulados e os valores medidos, da precisão do cálculo e da eficiência computacional. A trajetória de fluxo fractal foi relativamente ótima para o desempenho hidráulico e para o desempenho anti-entupimento.

ABSTRACT The fundamental solution to the problem of emitter clogging is to explore the optimal structure design of emitter and improve its anti-clogging ability. The research objective was to select the optimal structural form of the emitter flow path in drip irrigation systems using inferior water sources, which can provide theoretical support for improving the anti-clogging ability of the emitter itself and designing new emitter products. The selection of the flow path structure of the emitter has not been conducted on the basis of determining the appropriate simulation model with the condition of complex water quality. Therefore, the appropriate internal fluid movement model of the emitter was determined, the hydraulic performance and anti-clogging performance of the five nationally and internationally representative flow path structures were comprehensively evaluated, and finally the optimal structure of the emitter flow path was determined. The research results indicated that RNG k - ε model was the most suitable to simulate the flow field in the emitter by comprehensive analysis of the gap between simulated values and the measured values, the calculation accuracy and computational efficiency. The fractal flow path was relatively optimal for hydraulic performance and for anti-clogging performance. This study can provide theoretical support for improving the anti-clogging ability of the emitter itself and the design of the new emitter product. anticlogging anti sources products quality Therefore determined evaluated efficiency product

Abstract The objective of this paper is to problematize Ramón Grosfoguel’s statements, specifically regarding Aníbal Quijano. I claim that the accusation of “epistemic racism” that Grosfoguel made, according to which Quijano would not have recognized one of his intellectual debts, lacks foundation in authentic sources. Contextualizing the “coloniality of power” more broadly, I argue that Grosfoguel does not consider key aspects of the Peruvian author’s biography, both his political and intellectual background and the style of his work. In addition, examining the relationship between Quijano and the Peruvian and Latin American intellectual tradition will illuminate crucial paths in the trajectory of the “coloniality of power” theory. Thus, the grave accusation of “epistemic racism” that the Puerto Rican author made must be questioned since Quijano’s academic trajectory reveals that the elaboration of “coloniality” is endowed with a historicity according to which the ideas of race and racism are part of the overall theory-building process.

Résumé Cet article a pour but de problématiser les propos de Ramón Grosfoguel, en particulier à l’égard d’Aníbal Quijano. Je soutiens que l’accusation de “racisme épistémique” faite par Grosfoguel, selon laquelle Quijano n’aurait pas reconnu une de ses dettes intellectuelles, est dénuée de fondement dans des sources précises. En contextualisant plus largement la “colonialité du pouvoir”, j’argumente que Grosfoguel ne tient pas compte des aspects fondamentaux de la biographie de l’auteur péruvien, tant de sa formation politique et intellectuelle que du style de son œuvre. De même, un examen de la relation entre Quijano et la tradition intellectuelle péruvienne et latino-américaine éclairera des chemins cruciaux dans la trajectoire de la théorie de la “colonialité du pouvoir”. Ainsi, la grave accusation de “racisme épistémique” de l’auteur portoricain doit être remise en question, car la trajectoire académique de Quijano révèle que l’élaboration de la “colonialité” est dotée d’une historicité selon laquelle les idées de race et de racisme font partie du processus global de construction de la théorie. légard l égard dAníbal d Aníbal laccusation épistémique naurait n aurait intellectuelles précises colonialité pouvoir, pouvoir , pouvoir” jargumente j argumente lauteur auteur péruvien œuvre même latinoaméricaine latino américaine pouvoir. .

Resumo Este artigo pretende problematizar as afirmações de Ramón Grosfoguel, especificamente em relação a Aníbal Quijano. Sustento que a acusação de “racismo epistêmico” feita por Grosfoguel, de acordo com a qual Quijano não teria reconhecido uma de suas dívidas intelectuais, é destituída de embasamento em fontes precisas. Contextualizando de maneira mais ampla a “colonialidade do poder”, argumento que Grosfoguel não leva em conta aspectos fundamentais da biografia do autor peruano, tanto de sua formação política e intelectual quanto do estilo de sua obra. Também, um exame da relação entre Quijano e a tradição intelectual peruana e latino-americana iluminará veredas cruciais na trajetória da teoria da “colonialidade do poder”. Desse modo, a grave acusação de “racismo epistêmico” feita pelo autor porto-riquenho deve ser colocada em questão, pois a trajetória acadêmica de Quijano revela que a elaboração da “colonialidade” é dotada de uma historicidade segundo a qual as ideias de raça e racismo são parte do processo global da construção da teoria. epistêmico intelectuais precisas colonialidade poder, poder , poder” peruano obra Também latinoamericana latino americana poder. . modo portoriquenho porto riquenho questão

Resumen Este artículo pretende problematizar las afirmaciones de Ramón Grosfoguel, concretamente en relación con Aníbal Quijano.

Asimismo, un examen de la relación entre Quijano y la tradición intelectual peruana y latinoamericana iluminará caminos cruciales en la trayectoria de la teoría de la “colonialidad del poder”. De este modo, la grave acusación de “racismo epistémico” del autor puertorriqueño debe ponerse en tela de juicio, porque la trayectoria académica de Quijano revela que la elaboración de la “colonialidad” está dotada de una historicidad según la cual las ideas de raza y racismo forman parte del proceso global de construcción de la teoría. epistémico intelectuales precisas colonialidad poder, poder , poder” peruano obra Asimismo poder. . modo juicio

Résumé Cet article analyse la Banque Mondiale comme un acteur de la néo-libéralisation du capitalisme mondial, mettant l’accent sur ses fonctions de prêteur, conseiller et conseiller technique des gouvernements, agent de la société civile et producteur de recherches économiques pendant la période 1980-2023. En s’appuyant sur des sources primaires de l’institution elle-même et d’une vaste littérature spécialisée, l’étude montre comment l’action de la Banque Mondiale est devenue de plus en plus complète, politisée et intrusive, bien que présentant des variations dans la forme, le contenu et l’intensité de votre agenda politique et de vos pratiques opérationnelles. Larticle conclut que, dans un context mondial marqué par de grands changements économiques et politiques, une plus grande contestation des revenus économiques supposés universels et des incertitudes quant à l’avenir, la Banque mondiale est restée fidèle au paradigme politique néolibéral, cependant, elle a adopté une approche plus pragmatique, flexible, discrète et dépendante des circonstances et des priorités des emprunteurs (notamment ceux de grande envergure). néolibéralisation néo libéralisation laccent l accent prêteur gouvernements 19802023. 19802023 1980 2023. 2023 1980-2023 sappuyant s appuyant linstitution institution ellemême même dune d spécialisée létude étude laction action complète intrusive forme lintensité intensité opérationnelles politiques lavenir, lavenir avenir, avenir l’avenir néolibéral cependant pragmatique flexible notamment envergure. envergure . envergure) 1980202 198 202 1980-202 198020 19 20 1980-20 19802 1 2 1980-2 1980-

Abstract This article analyses the World Bank as an agent of the neoliberalization of global capitalism, with an emphasis on its functions as a lender, adviser and technical advisor to governments, civil society agent, and producer of economic research during the period from 1980 to 2023. Based on primary sources from the institution itself and extensive specialized literature, the article shows how the World Bank’s activities have become increasingly comprehensive, politicized, and intrusive, but with variations in form, content, and intensity in its political agenda and operational practices. It concludes that, in a global environment marked by major economic and political changes, greater contestation of supposedly universal economic recipes, and uncertainties about the future, the World Bank has remained faithful to the neoliberal political paradigm, but it has started to act in a more pragmatic, flexible, discreet way that depends on the circumstances and priorities of the borrowers (especially the larger ones). capitalism lender governments 198 2023 literature Banks s comprehensive politicized intrusive form content practices changes recipes future paradigm pragmatic flexible especially ones. ones . ones) 19 202 1 20 2

Resumo Este artigo analisa o Banco Mundial como agente de neoliberalização do capitalismo global, dando ênfase às suas funções de emprestador, conselheiro e assessor técnico de governos, agente da sociedade civil e produtor de pesquisas econômicas durante o período de 1980 a 2023. Com base em fontes primárias da própria instituição e ampla literatura especializada, o trabalho mostra como a atuação do Banco Mundial se tornou cada vez mais abrangente, politizada e intrusiva, porém com variações de forma, conteúdo e intensidade em sua agenda política e suas práticas operacionais. Conclui que, em um ambiente global marcado por grandes mudanças econômicas e políticas, maior contestação a receitas econômicas supostamente universais e incertezas quanto ao futuro, o Banco Mundial se manteve fiel ao paradigma político neoliberal, porém, passou a atuar de forma mais pragmática, flexível, discreta e dependente das circunstâncias e prioridades dos mutuários (especialmente os de maior volume). emprestador governos 198 2023 especializada abrangente intrusiva operacionais que políticas futuro neoliberal pragmática flexível especialmente volume. volume . volume) 19 202 1 20 2

Abstract We investigated how the FBI persecuted the Black Panther Party of the United States through the COINTELPRO program between 1968 and 1971, and verified that such practices follow a pattern similar to that of other counterintelligence activities mobilized in the repression of political organizations of the left and the black movement in the 20th Century, repeating a consolidated modus operandi at the time. In terms of methodology, we proposed a content analysis of primary sources little studied in Brazil – internal FBI memos and the final report of the US Senate Committee (“Church Committee”) dedicated to investigating government intelligence activities – and a systematization of secondary sources that have already analyzed the material in the United States. The relevance of the paper is to highlight the role of repression in studies of sociopolitical movements and mobilizations, mainly in the case of the Black Panthers – in which it occupies a specific importance to understand obstacles to develop the organization and its own dissolution process. 196 1971 th Century time methodology Church Committee” mobilizations process 19 197 1

Résumé Les recherches montrent comment le Black Panther Party des États-Unis a été persécuté par le FBI à travers le programme COINTELPRO entre 1968 et 1971. Ainsi, ces pratiques suivent un schéma similaire à celui d’autres activités de contre- renseignement mobilisées dans la répression des organisations politiques de gauche et du mouvement noir au XXe siècle, en répétant un modus operandi consolidé à l’époque. Méthodologiquement, il est proposé une analyse de contenu sur des sources primaires peu étudiées au Brésil - mémos internes du FBI et le rapport final du comité du Sénat américain (“Church Committee”) consacré à enquêter sur les activités de renseignement du gouvernement - et une systématisation des sources secondaires qui ont déjà analysé le matériel aux États-Unis. La pertinence de cet article est de souligner la place de la répression dans les études de mouvements et les mobilisations sociopolitiques, surtout dans le cas des Black Panthers - où elle revêt une importance particulière pour comprendre les obstacles au développement de l’organisation et son propre processus de dissolution.

Resumo Pesquisa-se como o Partido Pantera Negra dos Estados Unidos foi perseguido pelo FBI por meio do programa COINTELPRO entre os anos 1968 e 1971. Verifica-se, então, que tais práticas seguem um padrão similar ao de outras atividades de contrainteligência mobilizadas na repressão a organizações políticas da esquerda e do movimento negro no século XX, repetindo um modus operandi consolidado à época. Metodologicamente, propõe-se uma análise de conteúdo sobre fontes primárias pouco estudadas no Brasil – memorandos internos do FBI e o relatório final do comitê do Senado estadunidense (“Church Committee”) dedicado a investigar atividades de inteligência do governo – e uma sistematização de fontes secundárias que já analisaram o material nos Estados Unidos. A relevância do artigo consiste em destacar o lugar da repressão em estudos de movimentos e mobilizações sociopolíticas, sobretudo no caso dos Panteras Negras – no qual ela ocupa uma importância particular para compreender obstáculos ao desenvolvimento da organização e seu próprio processo de dissolução.
