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 (Introduction): Within the framework of the present capitalist system, human beings have become an important polluting agent. Current production and consumption processes do not consider the existence of finite natural resources and a planet incapable of treating the waste that the prevailing way of life generates. Given these circumstances, the study of non-linear models is of interest, which make a more rational use of the waste that the productive activity generates, favoring recycling mechanisms. The phenomenon of recycling becomes particularly relevant in the case of electrical and electronic devices, whose ability to be degraded and metabolized by planet Earth is extremely difficult. (Objective): Evaluate the feasibility of installing and starting a recycling plant for electrical and electronics items in the town of Bahía Blanca (Argentina), during 2021. (Methodology): The conventional method for evaluating investment projects was used, considering technical, legal and economic aspects. (Results): The project is not acceptable according to the profitability intended by the investor. The possibility of financing was also included, which made the project even less profitable, and the sensitivity of the results was measured, finding that the price should be 1.48 % higher than that used in the analysis. (Conclusions): Other alternatives must be explored to make this proposal profitable from an economic and financial point of view.

Resumen (Introducción): En el marco del sistema capitalista vigente, el ser humano se ha transformado en un agente significativo de contaminación. Las dinámicas productivas y de consumo actuales no contemplan la existencia de recursos naturales finitos y de un planeta incapaz de procesar los desperdicios que el modo de vida habitual genera. Dadas estas circunstancias, cobra interés el estudio de modelos no lineales, que hagan un uso más racional de los residuos derivados de la actividad productiva, los cuales favorezcan mecanismos de reciclaje. El fenómeno del reciclaje se vuelve, en particular, relevante para el caso de los artefactos eléctricos y electrónicos; la capacidad del planeta Tierra para degradarlos y metabolizarlos resulta sumamente difícil. (Objetivo): Evaluar la factibilidad de la instalación y puesta en marcha de una planta recicladora de artículos eléctricos y electrónicos en la localidad de Bahía Blanca (Argentina), durante el 2021. (Metodología): Se utilizó la metodología convencional de evaluación de proyectos de inversión, considerando aspectos técnicos, legales y económicos. (Resultados): El proyecto no es aceptable según la rentabilidad pretendida por el inversor. También se incluyó la posibilidad de un financiamiento, lo que hizo que el plan fuera menos rentable aún, y se midió la sensibilidad de los resultados: se halló que el precio debiera ser 1.48 % superior al utilizado en el análisis. (Conclusiones): Se deben explorar otras alternativas para lograr que el proyecto sea rentable desde el punto de vista económico-financiero.

Abstract (Introduction): The current cultivation of trees is insufficient to cover the national demand for wood, in this way small producers become an alternative solution to this situation, since despite having small areas, in the country there are abundant farms with these conditions; However, the current forest management scheme does not meet adequate standards for the incorporation of these small producers. (Objective): To present an adaptive forest management scheme (AFMS) to the needs of the small farmer, in addition, to demonstrate the institutional availability to change according to expert criteria. (Methodology): 1) the factors that influence the decision to adopt an agricultural or forestry production system were identified; 2) a profile of an ideal productive system that met the interests and preferences of the small producer was made, which was compared with the characteristics of agricultural and forestry production; 3) the proposal of an EMFA adjusted to the preferences and interest of the producer was made, which was also compared with the ideal profile; 4) three proposed change actions were presented to experts, obtaining different degrees of possibility of changes in the EMFA. (Results): The discrepancy of the forest management scheme for the cultivation of trees with the perspective that a small producer has on an ideal production system was evidenced, as well as the substantial improvement that an EMFA would have in the valuation of the small producer and the institutional availability to change the EMFA according to the perspective of the small producers. (Conclusions): The adjustment of the forest management scheme allows a greater adoption of the activity by the small producer, but it was recognized that any proposal that is made would be successful only if forest governance makes it more flexible and allows change.

Resumen (Introducción): El cultivo actual de árboles es insuficiente para cubrir la demanda nacional de madera, de este modo, los pequeños productores se tornan como una alternativa de solución ante esta situación, ya que pese a contar con áreas pequeñas, en el país son abundantes las fincas con estas condiciones; sin embargo, el esquema actual de manejo forestal no cumple con estándares adecuados para la incorporación de estos pequeños productores. (Objetivo): Presentar un esquema de manejo forestal adaptativo (EMFA) a las necesidades del pequeño productor, además de evidenciar la disponibilidad institucional al cambio, según el criterio experto. (Metodología): 1) se identificaron los factores que influyen en la decisión de adopción de un sistema productivo agrícola o forestal; 2) se realizó un perfil de un sistema productivo ideal que cumpliera con los intereses y preferencias del pequeño productor, el cual se confrontó con las características de la producción agrícola y forestal; 3) se efectuó la propuesta de un EMFA ajustado a las preferencias e interés del productor, que fue también confrontada con el perfil ideal; 4) se expusieron tres acciones de cambio propuestas ante expertos, obteniendo diferentes grados de posibilidad de cambios en el EMFA. (Resultados): Se evidenció la discrepancia del esquema de manejo forestal para el cultivo de árboles con la perspectiva que un pequeño productor tiene sobre un sistema de producción ideal, asimismo la mejora sustancial que un EMFA tendría en la valoración del pequeño productor y la disponibilidad institucional al cambio del EMFA, según la perspectiva de los pequeños productores. (Conclusiones): El ajuste del esquema de manejo forestal permite una mayor adopción del cultivo de árboles por parte del pequeño productor, pero se reconoció que cualquier propuesta que se realice lograría ser exitosa si la gobernanza forestal flexibiliza y posibilita el cambio.

Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

Resumen (Introducción): La vinaza se genera como residuo en la producción de etanol por fermentación-destilación de melazas/jugos de caña de azúcar, a razón de 13 L/L de etanol. Es un efluente líquido, ácido caracterizado por una elevada mineralización y valores de demanda química de oxígeno (DQO) de hasta 150 000 mg/L, siendo altamente contaminante. (Objetivo): Ealuar un proceso de tratamiento de vinazas con peróxido de hidrógeno, como fuente de radicales hidroxilos, en escala laboratorio. (Metodología): Las muestras de vinazas, de destilerías de la provincia de Tucumán, se caracterizaron según técnicas normalizadas de Standard Methods. Los ensayos de oxidación se realizaron con distintas relaciones de peróxido/vinaza, en un reactor semibatch, en condiciones ambientales, midiendo DQO como parámetro indicador del tratamiento. (Resultados): Al cabo de cinco días se logró una disminución de DQO del 85 % y un aumento del Índice de Biodegradabilidad. La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

Abstract (Introduction): The search for techniques and methods for managing sludge generated during wastewater treatment is necessary to ensure sustainable sanitation in the medium term in Latin America. An interesting approach involves converting sludge into a biosolid usable in agriculture through alkaline sanitization. (Objective): We evaluated this technique’s efficacy and economic and environmental viability for obtaining an agriculturally usable type A biosolid from municipal wastewater treatment plant (WWTP) sludge. (Methodology): To this end, the efficacy in reducing microbiological parameters was experimentally tested at the laboratory scale using quicklime, for anaerobic and aerobic WWTP sludge. The experimental results fed a benefit/cost analysis model and a life cycle assessment. (Results): It was confirmed that applying a 40 % lime dose allowed the obtention of a type A biosolid with non-detectable concentrations of pathogenic microorganisms, which remained in that condition for more than 30 days. Additionally, the benefit/cost and life cycle analyses concluded that this option would be more attractive than sludge disposal in a landfill, due to the corresponding savings in chemical compounds (fertilizers, agricultural lime). (Conclusions): Therefore, alkaline sanitization can be considered suitable for WWTP sludge management. Its application on a larger scale should be further investigated in the country and the Latin-American region, considering the risk associated to the presence of heavy metals too.

Resumen (Introducción): La búsqueda de técnicas y modelos de gestión del lodo generado durante el tratamiento de las aguas residuales es necesaria para garantizar un saneamiento sostenible a mediano plazo en América Latina. Una vía interesante consiste en convertir el lodo en un biosólido aprovechable en la agricultura por medio de la higienización alcalina. (Objetivo): Se evaluó la eficacia y la viabilidad económica y ambiental de esta técnica para la obtención de un biosólido tipo A aprovechable en la agricultura a partir de lodo de planta de tratamiento de aguas residuales (PTAR) ordinaria. (Metodología): Para ello se probó experimentalmente en escala de laboratorio la eficacia en el decaimiento de parámetros microbiológicos higienizados con cal viva, usando lodo anaeróbico y aeróbico de PTAR. Los resultados experimentales alimentaron un modelo de análisis de beneficio/costo y de ciclo de vida. (Resultados): Pudo corroborarse que la aplicación de dosis de cal de 40 % permitió obtener un biosólido tipo A con concentraciones de microorganismos patógenos no detectables, lo cual se mantuvo en esa condición por más de 30 días. Además, el análisis de beneficio/costo y de ciclo de vida permitieron concluir que esta opción sería más atractiva que la disposición del lodo en un relleno sanitario, debido al ahorro correspondiente en compuestos químicos (fertilizantes o cal agrícola) derivado de su aprovechamiento. (Conclusiones): Por lo tanto, la técnica de higienización alcalina puede considerarse como adecuada para la gestión del lodo de PTAR y su aplicación a mayor escala debe investigarse en mayor detalle en el país y la región latinoamericana, considerando también el riesgo de presencia de metales pesados en este subproducto.

Abstract This article intends to propose a methodology to characterize the Financial (In)Sustainability of Brazilian municipalities − materialized through the Municipal Financial Sustainability Index (ISFM) − as opposed to the methodology suggested by the Proposed Amendment to the Constitution (PEC) No. 188, whose agenda is to incorporate small municipalities considered unsustainable. Regarding the methods, we used quantitative, applied, descriptive and explanatory research, of the bibliographical and documentary type, in addition to descriptive statistics and correlation/linear regression. The results demonstrate that the ISFM is more robust compared to the methodology proposed by the PEC. The Index was applied to 5,570 Brazilian municipalities and the national average resulted in 56%. Most Brazilian municipalities classified themselves as “Sustainable” and the statistical analysis significantly demonstrated the existence of a positive correlation between the variables ISFM and Local Development.

Bisphenol A (BPA), an endocrine disruptor used in different commercial polymers, is a persistent pollutant commonly found in effluents. Conventional wastewater treatment processes have low chemical removal efficiency and are expensive. This work evaluated BPA removal using laccase enzyme produced from white rot fungus Pleurotus ostreatus. For the enzymatic production, residues of acai berry and pineapple were used as laccase inducers. The use of natural inducers led to a high enzyme production (1139 and 1031 U mL−1 to acai and pineapple, respectively). Bisphenol A was removed to a concentration lower than LOD (limit of detection) after 4 h. The degradation mechanism of BPA occurred by oxidation of methyl to hydroxymethyl group in a propane portion, with breakdown of the aromatic ring. The developed technology brought to the scene a new green, viable methodology, using vegetable waste, adding value to these residues and bringing an alternative to the BPA treatment.

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,

With the increase in life expectancy and the significant incidence of lesions of the musculoskeletal system, both the public and private sectors seek improvements in their products and processes in order to contribute to the health of the population. Every year tons of chicken eggshell (CES) from domestic consumption are released in environment and the present work aims the production of a synthetic ceramic bone substitute using the eggshell as a source of calcium ions. According to the methodology, 5, 10, 15 and 20 mol% of iron ions were used and the characterization assays demonstrated the formation of a double calcium iron phosphate - Ca9Fe(PO4)7. MG63 cells were cultured on test specimens to cell viability assay and to each doped group analyzed, verifying cell compatibility with the studied compounds, as well as a good adhesion profile. Scanning electron microscopy (SEM) of the cells showed that material surface favored cell adhesion and the results demonstrated that the production of the compounds were viable to Ca9Fe(PO4)7 phase. So, in the future, it will be possible to have a final comprehensive biological compatibility of the prototype for further in vitro and in vivo assays. system population CES (CES methodology 5 10 1 2 mol Ca9FePO47.

RESUMO: O ensino de anatomia vem se modificando ao longo dos anos, introduzindo métodos tecnológicos, principalmente após o período pandêmico. Questiona-se o uso exclusivo da tecnologia em comparação aos métodos tradicionais de dissecação e aulas teóricas presenciais no que diz respeito à aquisição de conhecimento. Este artigo analisou a percepção de conhecimento de alunos de diversos semestres do curso de Medicina Veterinária, comparando alunos que tiveram aulas apenas online com aqueles que tiveram aulas presenciais de Anatomia Descritiva dos Animais Domésticos. Para tanto, questões foram enviadas por meio de formulário, com preenchimento voluntário e anônimo, e posteriormente analisadas estatisticamente. Os resultados indicam que 11,5% dos alunos que cursaram a disciplina remotamente falharam na aplicação dos conhecimentos em outras disciplinas, enquanto nenhum aluno do ensino presencial relatou o mesmo. A maioria dos alunos, tanto dos grupos remotos quanto dos presenciais, lembram-se do assunto, mas revisam o conteúdo com frequência. Em relação ao conhecimento teórico, o grupo online (80,8%) compreendeu melhor à medida que o curso avançava, comparado a 59,6% do grupo presencial. A ligação entre Anatomia e outras disciplinas foi mais destacada pelo grupo presencial (30,8%) em comparação ao online (15,4%). Ambos os grupos concordam que o contacto físico com peças anatômicas é essencial, mas alguns consideram possível ter um primeiro contacto com imagens ou fotografias 3D. Baseado nesse estudo preliminar, conclui-se que as interações iniciais com a área de Anatomia devem incluir técnicas pedagógicas diversificadas com comunicação empática. A utilização de recursos tecnológicos modernos é um aliado do processo de ensino-aprendizagem, e após a abstração dos conteúdos é possível o uso singular da tecnologia na manutenção e atualização do conhecimento anatômico.

ABSTRACT: Anatomy teaching has been changing over the years, introducing technological methods especially after the pandemic period. An ongoing debate revolves around whether exclusive reliance on technology for anatomy classes, as opposed to traditional methods and face-to-face instruction, enhances knowledge acquisition. This study analyzed the knowledge perception of students from various semesters throughout the Veterinary Medicine course, comparing students who only had online classes with those who had face-to-face classes in Gross Anatomy of Domestic Animals. For this purpose, a questionnaire was distributed for voluntary and anonymous completion, and the responses were subsequently analyzed statistically. The results indicated that 11.5% of the students who took Anatomy remotely failed to apply the knowledge in other subjects, while no face-to-face learning student reported the same. Most students, both remote and face-to-face groups, remember the subject but review the content frequently. Regarding theoretical knowledge, the online group (80.8%) understood better as the course progressed, compared to 59.6% of the face-to-face group. The connection between Anatomy and other subjects was more highlighted by the face-to-face group (30.8%) compared to the online group (15.4%). Both groups agree that physical contact with anatomical specimens is essential; however, some believe that initial exposure through 3D images or photographs is feasible. We concluded based on this preliminary study that the initial interactions with the Anatomy field should include diversified pedagogical techniques with empathetic communication. The use of modern technological resources are allies in the teaching-learning process. Furthermore, after abstracting the contents, technology alone can effectively maintain and update anatomical knowledge.

Pinacolone and benzopinacolone derivatives are an important class of organic compounds due to their uses in polymer synthesis and more recently as biologically active compounds. The conventional synthesis of such molecules is generally done in two steps, the pinacol coupling followed by the pinacol/pinacolone rearrangement. Aiming to prepare benzopinacolone derivatives in a greener fashion, we present here a one-step synthesis from acetophenones in the presence of zinc and tert-butyl chloride. To develop the methodology, conditions to prepare 3,3-diphenyl-2-butanone from acetophenone were optimized. To assess the scope, different substituted acetophenones were tested, resulting in the corresponding benzopinacolones at moderate yields (20-50%) with high purity. Structural elucidations were performed by 1H and 13C NMR (nuclear magnetic resonance spectroscopy) and GC-MS (gas chromatography-mass spectrometry). steps pinacolpinacolone pinacolone rearrangement fashion onestep one step tertbutyl tert butyl chloride methodology 3,3diphenyl2butanone 33diphenyl2butanone diphenylbutanone 3,3 diphenyl 2 butanone 3 optimized scope tested 2050% 2050 20 50% 50 (20-50% purity H C nuclear spectroscopy GCMS GC MS gas chromatographymass chromatography mass spectrometry. spectrometry . spectrometry) 3diphenyl2butanone 33 3, 205 5 (20-50 (20-5 (20- (20 (2 (

Microparticulated whey protein can be used as a fat substitute in foods to enhance their nutritional value and improve their sensory and rheological characteristics. Microparticulation denatures whey proteins through heat treatment, followed by shear rate control to determine the aggregate sizes formed. The processing method used during microparticulation can modify the protein denaturation rate, which may enable the application of new proteins. This study sought to develop a methodology for quantifying whey protein fractions in commercial samples before and after microparticulation at different concentrations and physical states. The developed methodology proved to be applicable because of its selectivity, quantification, detection limits, and precision. The analyzed samples exhibited a higher denaturation rate for β-lactoglobulin than α-lactoalbumin; the denaturation rate varied among samples due to differences in the microparticulation process. characteristics treatment formed states selectivity quantification limits precision βlactoglobulin β lactoglobulin αlactoalbumin α lactoalbumin α-lactoalbumin process

Acetylsalicylic acid (ASA) synthesized in the practical classes of experimental organic chemistry is generally discarded after the classes. Thus, the objective of this work is to find an alternative application for ASA and to promote awareness about the recycling of chemicals in educational and research environments. In addition, it explores the subsequent application of this synthesized ASA in the creation of powdered developers for latent fingerprints. The adopted methodology included the recrystallization of the previously synthesized ASA, followed by the development of three distinct formulations of powdered developers, which include ASA, lignin, and methylene blue. Subsequently, these powders were used to identify latent fingerprints, demonstrating that they are promising substances for such applications.

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.

Citronellyl esters present broad applications in the cosmetic, pharmaceutical, and food industries due to their organoleptic and biological properties. Lipase-catalyzed acylation of citronellol has been a suitable way to obtain these natural esters on a high scale. This work describes the lipase-catalyzed acylation of citronellol through esterification and transesterification with linear acylating agents (C3-C18) using Novozym®435 as a biocatalyst. The results show that all esters achieved not less than 91% conversion from an esterification model, showing a good reaction profile. Citronellyl propionate and laurate were selected for study in a transesterification reaction model, and it resulted in a lower reaction time for ester conversions. As an example, we highlight citronellyl propionate production, which approximately 10 g L-1 of the product was obtained after 1.5 h of esterification compared to 2 min by transesterification. The final esters were purified with high purity (≥ 90%) and identified by gas chromatography-mass spectrometry (GC-MS), and their structures were elucidated by 1H and 13C nuclear magnetic resonance (NMR). Enzyme recycling was evaluated and Novozym®435 was able to be applied for at least 20 cycles. Results demonstrated the efficiency of acylation reactions catalyzed by this enzyme and showed the potential of the methodology for the production and purification of flavor esters. cosmetic pharmaceutical properties Lipasecatalyzed Lipase scale lipasecatalyzed lipase C3C18 CC C3 C18 C (C3-C18 Novozym435 Novozym 435 Novozym®43 biocatalyst 91 model profile conversions example 1 L1 L L- 15 5 1. ≥ ( 90% 90 chromatographymass chromatography mass GCMS, GCMS GC MS , (GC-MS) H NMR.
