Lipases have been used in industrial processes as biocatalysts for transesterification reactions. The synergism between enzymes and magnetic properties may be reached by using magnetic nanoparticles (MNPs) as support to immobilize them in aggregate structures, denominated by magnetic crosslinked enzyme aggregates (MCLEA). One of the advantages of such supports is the possibility of using magnetic separation for enzyme recovery, reducing costs and allowing reuse in continuous systems. Here, porcine pancreatic lipase (PPL) was immobilized onto functionalized magnetite support (Fe3O4-APTS) with a protein binding efficiency of 78.84%. Physical and chemical properties of the nanoparticles and immobilized lipase were characterized by X-ray diffraction (XDR), transmission electron microscopy (TEM), infrared spectroscopy (FTIR), dynamic light scattering (DLS), zeta potential, vibrating sample magnetometer measurements (VSM), and 57Fe Mössbauer spectroscopy. The immobilized lipase additionally exhibited improved stability across wide pH and temperature ranges compared with free lipase. The immobilized derivate also attained good reusability, maintaining 61.37% of its initial activity after 6 reaction cycles. Through magnetic behavior and also because of its surface modification to crosslinking the enzyme, the MCLEA produced in this work has enhanced the biocatalytic activities of PPL. reactions MNPs (MNPs structures MCLEA. .

Abstract Conservation units are specially protected territorial spaces whose primary goals are to preserve biodiversity and natural resources. Thus, this paper aims to investigate the spatial-temporal dynamics of land-use and land-cover classes and hotspots in a conservation unit in the Caatinga region. We assessed land-use and land-cover classes based on Mapbiomas’s data from 2002 to 2021. Then, we analyzed the hot spots made available by Programa Queimadas database, for the rainy and dry seasons, as well as data recorded on a yearly basis between 2002 and 2021. The class of agricultural activities in the buffer zone has increased; changes in the hotspots’ distribution pattern were observed, such as displacement from the Park’s central area towards the buffer zone’s. Furthermore, 12 hotspots tended to increase in the dry season, over the 20-year assessment process. Insights into the growth of agriculture and changing hotspot patterns assist in creating more effective conservation strategies. resources Thus spatialtemporal spatial temporal landuse land use landcover cover region Mapbiomass Mapbiomas s 200 2021 Then database seasons increased observed Parks Park zones. zones s. zone’s Furthermore 1 season 20year year 20 process strategies 202 2

ABSTRACT The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups. you conserve wellknown well known biologists plans context science territory South Brazil dimensions =Mollusca Mollusca (=Mollusca taxonomists Recently unprecedented collective malacologists 3 TCBF , (TCBF) realtime real Metazoan far 5000 5 000 5,00 3552 552 3,55 follows 10 (1 spp., spp spp. 6 ( 35 (3 43 (4 92 (9 629 (62 2,737 2737 2 737 (2,73 spp.. . study groups (TCBF 500 00 5,0 355 55 3,5 1 4 9 62 2,73 273 73 (2,7 50 0 5, 3, 2,7 27 7 (2, 2, (2

Abstract The surface of Fe3O4 nanoparticles is very reactive and can oxidize to γ-Fe2O3 (maghemite) and α-Fe2O3 (hematite) structures. Based on this, the oxidation process of Fe3O4 nanoparticles must be prevented, and one of the strategies is surface functionalization with organic or inorganic molecules. Thus, this study analyzed the thermal behavior of Fe3O4 and Fe3O4-EDTA nanoparticles using X-ray diffraction (XRD), simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC). Results showed that γ- Fe2O3 was obtained as an intermediate in Fe3O4 and Fe3O4-EDTA decomposition, as confirmed by TG-DTA and DSC curves. Moreover, Fe3O4-EDTA exhibited a temperature peak (Tp = 573.5°C) of phase transformation (γ-Fe2O3 → α-Fe2O3) higher than that of Fe3O4 (Tp = 533.0°C), confirming that EDTA molecules stabilized the nanoparticles efficiently. The kinetic behavior of samples changed, and the activation energy for functionalized samples decreased.

Abstract: En | Text: En | PDF: En

The use of selective barriers as resorbable membranes has become a routine clinical procedure for guided bone regeneration. Therefore, the production of membranes with a low inflammatory potential during their resorption process has become the goal of a considerable number of researches. Aim The purpose of the present study was to evaluate the biocompatibility of poly (L- lactic acid) (PLLA) and biocelulose membranes (BC) inserted in the subcutaneous tissue on the dorsum of rats. Methods Fifteen animals underwent surgical procedures for the insertion of 4 types of membranes: COL (Collagen membrane) – Control Group; BC (Biocellulose membrane); BCAg (Biocellulose membrane impregnated with Silver); PLLA (Poly (L-lactic acid) membrane). All membrane types were inserted into each animal. Animals were euthanized after 3, 7, and 15 days of the surgical procedure. Descriptive histological analyses were carried out to investigate host tissue reaction to membrane presence by assessing the anti-inflammatory process composition associated with the membrane resorption and the presence of foreign-body reaction or encapsulation. Results The BC membranes showed a higher degree of inflammation and poor pattern of integration with the surrounding tissues than the PLLA and COL membranes. Conclusion The PLLA and COL membranes present better biocompatibility than the BC membranes.

Objective: Positive psychology interventions (PPIs) incorporate principles of personal strengths with the view that mental health recovery transcends symptom relief. Severe psychiatric conditions, such as schizophrenia, may benefit from such interventions. This study aims to gather the current evidence on the impact of PPIs on increasing well-being in patients on the schizophrenia spectrum and assess reductions in negative or positive symptoms. Methods: A systematic review of PPI studies with schizophrenia-spectrum patients was carried out following PRISMA recommendations. The PubMed, PsycINFO, Web of Science, and Scopus databases were searched for relevant publications in order to understand the possible effects of these interventions on well-being measures and psychotic symptoms in this population. Results: Nine studies (four controlled) were included. Meta-analysis of the controlled studies showed a significant effect (p = 0.04) for improvement of well-being (Z = 2.01). Overall, the reviewed evidence suggests well-being improvement. The effect on reduction of negative symptoms was unclear. Conclusion: Used as an adjunctive therapy, PPIs appear to be a promising resource for patients on the schizophrenia spectrum, with possible effects on well-being and symptom reduction.

RESUMO Nos últimos anos há um interesse crescente no uso de diversos resíduos agroindustriais. No Brasil, as indústrias de alimentos acumulam uma enorme quantidade de resíduos, principalmente as de processamento de frutos cítricos.Entre as possibilidades de valorização destes resíduos, a digestão anaeróbia é uma alternativa promissora na geração de energia renovável e controle da poluição. Nesse sentido, esse estudo avaliou a digestão anaeróbia de água residuária citrícola, visando à produção biológica de hidrogênio a partir de três inóculos: (1) Clostridium Acetobutylicum ATCC 824,(2) Clostridium Beijerinckii ATCC 10132 e (3) consórcio anaeróbio obtido da água residuária citrícola. O experimento foi realizado em 51h, em triplicatas de reatores anaeróbios em batelada, alimentados com 2 fontes distintas de carbono: glicose (10,7 g DQO L-1) e água residuária citrícola (10,0 g DQO L-1), headspace preenchido com N2 (99,99%), pH inicial 7,0 e mantidos a 37°C, sob modo estático. Nos reatores alimentados com glicose foram verificados geração de hidrogênio apenas com os inóculos 1 e 2, que foram, respectivamente, de 36,8 mmol L-1 e 64,1 mmol L-1. Nos reatores operados com água residuária citrícola foram obtidos 21,2; 15,7 e; 37,6 mmol H2 L-1 com os inóculos 1; 2 e 3, respectivamente. Além disso, foram verificadas gerações expressivas de etanol para todos os inóculos testados nos reatores alimentados com glicose. Na caracterização do consórcio anaeróbio citrícola foi verificado predomínio de bacilos Gram + e quantificados os gêneros de bactérias anaeróbias geradoras de H2 (UFC mL-1): Clostridium sp. (3x105), Bacteroides sp. (4x105), Lactobacillus sp. (4x105), Streptococcus sp. (5x104), e Veillonella sp. (3x105), revelando diversidade elevada de bactérias anaeróbias produtoras de hidrogênio presentes na água residuária agroindustrial. Tais resultados ressaltam que a geração de hidrogênio pode ocorrer em vias metabólicas distintas com consequente favorecimento na geração de biocombustíveis como etanol ou butanol.

ABSTRACT In recent years there has been a growing interest in the use of various agro-industrial wastes. In Brazil, the food industries accumulate an enormous amount of waste, especially those that process citrus fruits. Among the possibilities for valuing these residues, anaerobic digestion is a promising alternative in the generation of renewable energy and pollution control. In this sense, this study evaluated the anaerobic digestion of citrus wastewater, aiming at the biological production of hydrogen from three inocula: (1) Clostridium Acetobutylicum ATCC 824, (2) Clostridium Beijerinckii ATCC 10132 and (3) anaerobic consortium obtained from citrus wastewater. The experiment was carried out in 51h, in triplicates of anaerobic batch reactors, fed with 2 different carbon sources: glucose (10.7 g COD L-1) and citrus wastewater (10.0 g COD L-1), headspace filled with N2 (99.99%), initial pH 7.0 and maintained at 37 ° C, under static mode. In the reactors fed with glucose, hydrogen generation was verified only with the inocula 1 and 2, which were, respectively, 36.8 mmol L-1 and 64.1 mmol L-1. In the reactors operated with citrus wastewater, were obtained 21.2; 15.7 e; 37.6 mmol H2 L-1 with inocula 1; 2 and 3, respectively. In addition, expressive generations of ethanol were verified for all inocula tested in the reactors fed with glucose. In the characterization of the citrus anaerobic consortium, a predominance of Gram + bacilli was verified and the genera of anaerobic H2-generating bacteria (UFC mL-1) were quantified: Clostridium sp. (3x105), Bacteroides sp. (4x105), Lactobacillus sp. (4x105), Streptococcus sp. (5x104), and Veillonella sp. (3x105), revealing a high diversity of anaerobic hydrogen-producing bacteria present in agro-industrial wastewater. Such results emphasize that the generation of hydrogen can occur in different metabolic pathways with consequent favor in the generation of biofuels such as ethanol or butanol.

RESUMO A produção de biodiesel tem crescido e ganhado destaque no cenário energético mundial. Com isso, seu principal coproduto, o glicerol bruto (GB), tem acompanhado esse aumento, ocasionando a formação de grandes estoques deste resíduo. Uma alternativa promissora para a sua redução consiste na utilização por processos biológicos anaeróbios visando à produção de biogás, tanto hidrogênio (H2) quanto metano (CH4). Sabe-se que a eficiência dessa bioconversão aumenta por meio da codigestão com outros resíduos orgânicos. Assim, o objetivo deste estudo consistiu na codigestão do GB, proveniente da produção de biodiesel a partir de óleos residuais domésticos, com vinhaça citrícola (VC), em dois estágios sequenciais. No 1º estágio (Ensaio 1), o reator anaeróbio foi operado em batelada, alimentado com 5 g DQO L-1 GB e 5 g DQO L-1 VC, na presença de cultura mista pertencente ao gênero Clostridium sp., a 37 °C, pH 5,5, headspace com N2, gerando 4,48 mmol H2 L-1 em 112 h de experimento, sendo consumidos 93,19 % de GB e 74,00 % de glicose. Um ensaio controle (Controle 1) foi montado com apenas 5 g DQO L-1 GB, não sendo verificada produção de H2. O efluente gerado no Ensaio 1 (200 mL) foi usado como substrato no 2º estágio (Ensaio 2) por um inóculo in natura identificado por consórcio de bactérias anaeróbias fermentativas e archaeas metanogênicas, no reator anaeróbio metanogênico (500 mL), headspace com N2, pH 7,0, a 37 °C, gerando 229,08 mmol CH4 L-1 em 624 h de operação. Além disso, 87,34 % da DQO e 93,75 % do metanol proveniente do GB foram consumidos. O efluente gerado pelo Controle 1 produziu apenas 40,58 mmol CH4 L-1 (Controle 2). Dessa forma, constatou-se que a codigestão elevou a geração de biogás, com consumos de resíduos orgânicos e tóxicos presentes no GB por meio dos sistemas integrados.

ABSTRACT The biodiesel production has grown and it gained prominence in the global energy scenario. As a result, its main co-product, crude glycerol (CG), has accompanied this increase, causing the formation of large stocks of this residue. A promising alternative for its reduction is the use by anaerobic biological processes aiming at the biogas production, as hydrogen (H2) as methane (CH4). It is known that the efficiency of this bioconversion increases through co-digestion with other organic waste. Thus, the objective of this study consisted in the co-digestion of CG, from the biodiesel production through waste cooking oils, with citrus vinasse (CV), in two sequential stages. In the 1st stage (Assay 1), the anaerobic reactor was operated in batch, fed with 5 g COD L-1 CG and 5 g COD L-1 CV, in the presence of a mixed culture belonging to the genus Clostridium sp., at 37 °C, pH 5.5, headspace with N2, generating 4.48 mmol H2 L-1 in 112 h of experiment, being consumed 93.19 % of CG and 74.00 % of glucose. A control assay (Control 1) was assembled with only 5 g COD L-1 CG, without H2 production. The effluent generated in Assay 1 (200 mL) was used as a substrate in the 2nd stage (Assay 2) by an inoculum in natura identified by a consortium of anaerobic bacteria and methanogenic archaea, in the anaerobic methanogenic reactor (500 mL), headspace with N2, pH 7.0, at 37 °C, generating 229.08 mmol CH4 L-1 in 624 h of operation. In addition, 87.34 % of COD and 93.75 % of methanol from CG were consumed. The effluent generated by Control 1 produced only 40.58 mmol CH4 L-1 (Control 2). Thus, it was found that co-digestion increased the biogas generation, with consumption of organic and toxic waste present in CG through integrated systems.

ABSTRACT Introduction: In the field of information user studies, the shift from the system-centered to the user-centered information paradigm brought to the forefront individual and cognitive aspects of informational activities. This point of view was criticized by emerging social approaches for neglecting social and contextual aspects. This movement generates tensions between researchers who adopt positions focused on the centrality on the user, or on the context or some intermediate position between the two poles, which inevitably interferes with the results of their researches. Objective: The article aims to analyze the Actor-Network Theory (ANT) as an alternative to the reductionist polarities that are present in the field of user studies. Methodology: The analysis was carried out through a bibliographic review on user studies, informational behavior, and ANT. Results: The study reveals a differentiated approach to tracking informational activities, since it considers that information users, whether individual or collective, continuously exchange properties on the same plane, without the aforementioned polarization or search for intermediate positions. Conclusions: The article presents the ART as a coherent and opportune alternative for the apprehension of contemporary informational phenomena.

RESUMO Introdução: No campo dos estudos de usuários da informação, a mudança do paradigma centrado no sistema para o centrado no usuário da informação trouxe aspectos individuais e cognitivos das atividades informacionais para o primeiro plano. Esse ponto de vista foi criticado por abordagens sociais emergentes por negligenciar aspectos sociais e de contexto. Esse movimento gera tensões entre investigadores que adotam posicionamentos focados na centralidade no usuário, ou no contexto ou em alguma posição intermediária entre os dois polos, o que inevitavelmente interfere nos resultados de suas pesquisas. Objetivo: O artigo objetiva analisar a Teoria Ator-Rede (TAR) como uma alternativa às polaridades reducionistas presentes no campo de estudos de usuários. Metodologia: A análise foi realizada por meio de revisão bibliográfica sobre estudos de usuários, comportamento informacional e TAR. Resultados: O estudo revela uma abordagem diferenciada no rastreamento de atividades informacionais ao considerar que usuários da informação, sejam eles individuais ou coletivos, continuamente trocam propriedades em um mesmo plano, sem a referida polarização ou a busca por posições intermediárias. Conclusões: O artigo apresenta a TAR não apenas como uma alternativa coerente, mas oportuna para a apreensão de fenômenos informacionais contemporâneos.

Abstract Since 1998, a national assessment policy called the National High School Examination (ENEM) has been implemented in Brazil. In 2009, it underwent modifications that included the content of the exam questions related to Physical Education. The paper analyzes how Physical Education is addressed by the questions and what relationships are established with other areas of knowledge. It is characterized as a qualitative research of an exploratory nature and uses the documentary critical analysis as a methodology. The sources are: 49 questions related to Physical Education from nine editions of the test (2009 to 2017); the National Curricular Guidelines for High School; the Basic Document of ENEM, and the Reference Matrix of ENEM. The results demonstrate that the content of Physical Education is presented in the questions in two different ways: a) as a purpose, understood as the act of using them to achieve the objectives attributed to different body practices and; b) as a means of interacting with other areas of knowledge. The conclusions reveal that the attributed uses and meanings exceed its practicad dimension and reinforce the multidisciplinary character of Physical Education, interacting with the different areas of curricular knowledge in Brazil’s high schools.

Resumen Desde 1998 se ha implementado en Brasil una política nacional de evaluación llamada “Examen Nacional de la Educación Secundaria (ENEM)”. En 2009 pasa por modificaciones que incluyen los contenidos de Educación Física (EF) en las preguntas del examen. El artículo analiza la manera como la Educación Física es incluida entre las preguntas y qué relaciones establece con otras áreas de conocimiento. Se caracteriza por ser una investigación cualitativa, de naturaleza exploratoria y que utiliza como metodología el análisis documental crítico. Las fuentes consisten en 49 preguntas relacionadas con la Educación Física de nueve ediciones del examen (2009 a 2017), además de las Orientaciones Curriculares Nacionales para la Escuela Secundaria, Documento Básico de ENEM y Matriz de Referencia de ENEM. Los resultados muestran que los contenidos de Educación Física se presentan en las preguntas de dos maneras: a) como fin, entendidos como el acto de usarlos para lograr los propósitos atribuidos a las diferentes prácticas corporales, y b) como medio, entendidos como el acto de relacionarlos con otras áreas de conocimiento. Las conclusiones muestran que los usos y significados atribuidos a la Educación Física exceden su dimensión práctica y refuerzan su naturaleza multidisciplinaria, interactuando con y entre las diferentes áreas del conocimiento curricular en la escuela secundaria brasileña.
