Resumo A coruja-das-torres americana (Tyto furcata) vive em ambientes urbanos e se alimenta principalmente de pequenos roedores, sendo de grande importância no controle biológico de pragas. O objetivo deste trabalho foi descrever os hábitos alimentares, parentais e reprodutivos de um casal de corujas-das-torres americanas, naturalmente vivendo fora de uma residência na zona urbana do município de Campos dos Goytacazes, estado do Rio de Janeiro, Brasil. Uma caixa de madeira foi instalada em uma parede externa da casa, monitorada por uma câmera de vídeo. Uma planilha foi criada para manter o controle das observações registradas. A fêmea pôs quatro ovos, e após período de incubação de 30-32 dias todos os ovos eclodiram, mas apenas dois filhotes sobreviveram após o canibalismo entre os filhotes. Inicialmente, o macho fornecia a comida aos filhotes e a fêmea permanecia no ninho cuidando da ninhada. Depois de cerca de um mês, a fêmea também começou a sair do ninho e voltar com a presa, que era oferecida aos filhotes, com o macho também continuando com esse comportamento. Os filhotes deixaram o ninho em setembro de 2017. Os dados obtidos mostram a existência de cooperação e divisão de tarefas entre corujas machos e fêmeas durante o período reprodutivo.

Abstract The American Barn Owl (Tyto furcata) lives in urban, periurban and wild environments and feeds mainly on small rodents, meaning it has great importance in the biological control of pests. The aim of this work was to describe the reproductive, parental and eating habits of a pair of American barn owls naturally living outside a residence in the urban area of the municipality of Campos dos Goytacazes, Rio de Janeiro state, Brazil. A wood box was installed on an outside wall of the home, monitored by a video camera. A spreadsheet was created to keep track of the observations recorded. The female laid four eggs, and after an incubation period of 30-32 days all the eggs hatched, but only two chicks survived after cannibalism among the chicks. Initially, the male provided the food to the chicks and the female remained in the nest caring for the brood. After approximately a month, the female also began to leave the nest and return with prey, which was offered to the chicks, with the male also continuing this behavior. The chicks left the nest in September, 2017. The data obtained show the existence of cooperation and division of tasks between male and female owls during the reproductive period.

In the present work, synthetic slags (FeO-SiO2-CaO-P2O5-Al2O3-TiO2-V2O5 system) mimicking the composition of the slag inclusions of Ipanema were solidified at different cooling rates. FactSage software was used to calculate the slag’s phase equilibria from 500ºC to 1600°C to guide the microstructural characterisation. The samples solidified with slower cooling rates featured wüstite dendrites and a eutectic-like matrix, with intradendritic (Al,V,Ti)-containing iron spinel precipitates in the wüstite. The rapidly solidified slag showed refined wüstite dendrites surrounded by a Fe-O-Si-Ca-containing amorphous single-phase matrix without intradendritic (Al,V,Ti)-containing iron spinel precipitation. The comparison of the calculated phase diagram with the as-cast microstructures showed a few discrepancies. For instance, the FactSage’s database must be updated to consider the simultaneous solubility of Al, V and Ti in the thermodynamic description of the spinel phases, such as FToxid-SP-V, FToxid-SPINA, FToxid-TiSp and (FeO)2(TiO2)(s). Finally, the intradendritic precipitation of (Al,V,Ti)-containing iron spinel phases in the wüstite of the slag inclusions indicated that an Ipanema’s iron artefact was exposed to high service temperatures between 750 and 1050ºC.

Chagas disease, caused by the parasite Trypanosoma cruzi, occurs most commonly in Latin America. As the treatment is highly toxic and ineffective in the chronic phase of the disease, alternative treatments are needed. Through quantitative structure-activity relationship modeling (QSAR) analysis using ligand-based and structure-based virtual screening methods, we predicted the trypanocidal potential of 47 neolignans against three targets, the enzymes cruzain, trypanothione reductase, and sterol 14-alpha demethylase. A combined analysis allowed for the selection of potent inhibitors against Trypanosoma cruzi. Of these compounds, two were isolated and shown to inhibit the growth of epimastigotes at concentrations of 9.64 and 8.72 µM, and trypomastigote forms at 4.88 and 2.73 µM. Therefore, the compounds (2R, 3R)-2,3-dihydro-2 (4 methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (46) and ottomentosa (47) may be a good option of growth inhibitors for the parasite stages and warrant additional study.

RESUMO Considerando a relevância do cajueiro e a limitação imposta pelo estresse salino em regiões semiáridas, o uso de alternativas capazes de mitigar os efeitos deletérios em decorrência da salinidade são de grande importância ao setor produtivo. O uso de plantas enxertadas, principalmente com porta-enxertos de materiais tolerantes, influencia no acúmulo de íons tóxicos nas folhas das mudas enxertadas. Assim, o objetivo deste trabalho foi avaliar características morfofisiológicas e concentração foliar de Na+, K+, Ca+2 de combinações de copa e porta-enxerto de cajueiro anão precoce, contrastantes à salinidade. O experimento foi realizado em delineamento inteiramente casualizado, com cinco repetições, tendo os tratamentos dispostos em arranjo fatorial de 4 × 3, correspondentes a quatro combinações de mudas enxertadas (auto-enxerto CCP 09/CCP 09, CCP 09/CCP 76, auto-enxerto CCP 76/CCP 76 e CCP 76/CCP 09) e a três concentrações de NaCl (0-controle, 50 e 100 mM L-1). Foram avaliados altura, número de folhas, área foliar, massa seca, índice de tolerância e concentração foliar de Na+, K+ e Ca+2 após 30 dias da aplicação das concentrações de NaCl. A combinação copa/porta-enxerto CCP 76/09 apresentou tolerância à salinidade de 50 mM L-1, devido ao aumento da área foliar e número de folhas. A combinação copa/porta-enxerto CCP 76/09 foi mais adequada, pois manteve a concentração foliar de K+ e o menor concentração de Na+.

ABSTRACT Considering the cashew tree’s relevance and the limitations imposed by salinity stress in semi-arid regions, the use of alternatives capable of mitigating the harmful effects due to salinity is of great importance to the production sector. The use of grafted plants, especially with rootstock made of tolerant materials, influences the accumulation of toxic ions in leaves of grafted seedlings. Thus, the objective of this work was to evaluate morphophysiological characteristics and leaf concentrations of Na+, K+ and Ca+2 of combinations of scion and rootstock of early dwarf cashew, contrasting in terms of salinity tolerance. The experiment was carried out in a completely randomized design with five replicates, in a 4 × 3 factorial arrangement, corresponding to four dwarf cashew scion/rootstock combinations (self-graft CCP 09, CCP 09/CCP 76, self-graft CCP 76, and CCP 76/CCP 09) and three NaCl concentrations (0, 50, and 100 mM L-1). Height, number of leaves, leaf area, dry matter, tolerance index and leaf concentrations of Na+, K+ and Ca+2 were evaluated after 30 days of application of NaCl concentrations. The scion/rootstock combination CCP 76/09 showed tolerance to 50 mM L-1, due to the increase of leaf area and number of leaves. The scion/rootstock combination CCP 76/09 was more suitable, as it kept the leaf K+ concentration and had the lowest Na+ concentration.

Abstract Pseudomonas aeruginosa is a non-lactose fermenting Gram-negative bacteria responsible for causing numerous nosocomial infections. The present research aimed to analyze the anti-Pseudomonas aeruginosa potential of 2-Chloro-N-(4-fluoro-3-nitrophenyl)acetamide (A8). The antibacterial potential of A8 was evaluated from the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Association using the checkerboard method. MIC and MBC values were 512 µg/mL for all P. aeruginosa strains evaluated, demonstrating predominantly bactericidal activity. Furthermore, when A8 was associated with the drug ceftriaxone, pharmacological additivity and indifference were evidenced. In this sense, the synthetic amide was interesting, since it demonstrates the potential to become a possible candidate for an antimicrobial drug.

Resumo Pseudomonas aeruginosa é uma bactéria Gram-negativa não fermentadora de lactose, responsável por causar inúmeras infecções nosocomiais. A presente pesquisa teve como objetivo analisar o potencial anti-Pseudomonas aeruginosa da molécula 2-Cloro-N-(4-fluoro-3-nitrofenil)acetamida (A8). O potencial antibacteriano do A8 foi avaliado a partir da Concentração Inibitória Mínima (CIM), Concentração Bactericida Mínima (CBM) e Associação pelo método de checkboard. Os valores de CIM e CBM foram de 512 µg/mL para todas as cepas de P. aeruginosa avaliadas, demonstrando atividade predominantemente bactericida. Além disso, quando o A8 foi associado ao fármaco ceftriaxona, evidenciou-se aditividade e indiferença farmacológica. Nesse sentido, a amida sintética se mostrou interessante, pois demonstra potencial para se tornar um possível candidato a fármaco antimicrobiano.

Abstract The purpose of this in vitro study was to test the hypothesis that fluoride treatment can prevent dental erosion on fluorotic enamel of different severities. It followed a 3×2 factorial design, considering a) fluorosis severity: sound (TF0, Thylstrup-Fejerskov Index), mild (TF1-2), moderate (TF3-4); and b) fluoride treatment: 0 (negative control) and 1150ppmF. Human molars with the three fluorosis severities (n=16, each) were selected and randomly assigned to the two fluoride treatments (n=8). Enamel blocks (4×4mm) were prepared from each tooth and subjected to a dental erosion cycling model, for 10 days. The daily cycling protocol consisted of erosive challenges (1% citric acid, pH 2.4), interspersed by periods of immersion in artificial saliva, and three 2-minute treatments with either 0 or 1150ppm F. The enamel volume loss (mm3) was calculated by subtracting values obtained by microtomography before and after cycling. Two-Way ANOVA showed no significant interaction between fluorosis severity and fluoride treatment (p=0.691), and no significant effect for either fluorosis severity (TF0 mean±standard-deviation: 13.5(10-2±0.42(10-2, TF1-2: 1.50(10-2±0.52(10-2, TF3-4: 1.24(10-2±0.52(10-2, p=0.416) or treatment (0ppmF: 1.49(10-2±0.53(10-2; 1150ppmF: 1.21(10-2±0.42(10-2; p=0.093), when evaluated independently. Considering the limitations of this in vitro study, the presence and severity of fluorosis in enamel do not appear to affect its susceptibility to dental erosion. Fluoride treatment was not effective in preventing the development of dental erosion in both sound and fluorotic enamel substrates under our experimental conditions.

Resumo Este estudo in vitro foi testou a hipótese de que o tratamento com flúor pode prevenir a erosão dentária no esmalte fluorótico de diferentes severidades. O objetivo deste estudo foi: investigar o efeito protetor dos fluoretos contra a erosão e abrasão simuladas no esmalte fluorótico. Seguiu um desenho fatorial 3×2, considerando a) severidade da fluorose em 3 níveis: hígido (TF0, Índice Thylstrup-Fejerskov), suave (TF1-2), moderada (TF3-4); b) tratamento com flúor: 0 (controle negativo) e 1150ppmF. Molares humanos com as três severidades de fluorose (n=16, cada) foram selecionados e distribuídos aleatoriamente para os dois tratamentos com flúor (n=8). Blocos de esmalte (4×4mm) foram preparados a partir de cada dente e submetidos a um modelo de ciclo de erosão dentária, por 10 dias. O protocolo de ciclagem diária consistiu em seis desafios erosivos de 5 minutos (1% de ácido cítrico, pH 2,4), intercalados por seis períodos de imersão em saliva artificial e três tratamentos de 2 minutos com 0 ou 1150ppmF. O volume do esmalte perdido foi calculado subtraindo o perfil superficial 3D obtido por microtomografia antes e depois da ciclagem. A ANOVA de dois fatores não mostrou interação significativa entre a severidade da fluorose e o tratamento com flúor (p = 0,691) e nenhum efeito significativo para a severidade da fluorose (TF0 média+/desvio padrão: 13,5(10-2±0,42(10-2, TF1-2: 1,50(10-2±0,52(10-2, TF3-4: 1,24(10-2±0,52(10-2, p=0,416) ou tratamento (0: 1,49(10-2±0,53(10-2; 1150ppmF: 1,21(10-2±0,42(10-2, p=0,093), quando avaliados independentemente. Considerando as limitações deste estudo in vitro, a presença e severidade da fluorose no esmalte não parece afetar sua suscetibilidade à erosão dentária. O tratamento com flúor não foi eficaz na prevenção do desenvolvimento da erosão dentária em esmalte hígido e fluorótico, sob as condições experimentais utilizadas.

Resumo Vários estudos enfatizam o uso de pelotas de coruja em inventários de pequenos mamíferos em áreas naturais com elevada riqueza de espécies raras, mas poucas localidades da Mata Atlântica brasileira têm sido inventariadas por esse método. O presente estudo documenta a composição de espécies e abundância de pequenos mamíferos na dieta de Tyto furcata em uma área urbana do município de Campos dos Goytacazes, Rio de Janeiro, Brasil, discutindo a relevância de um novo registro de um raro marsupial do gênero Cryptonanus na Mata Atlântica. Foram analisadas 265 pelotas regurgitadas por um casal de T. furcata entre novembro de 2016 e setembro de 2017, encontradas abaixo de uma caixa de nidificação. A análise das amostras permitiu encontrar o total de 596 indivíduos de quatro espécies pequenas de mamíferos. O roedor exótico Mus musculus foi predominante entre os itens alimentares (98,3%), enquanto os roedores nativos Necromys lasiurus (1,3%) e Holochilus brasiliensis (0,17%) foram bem mais raros. Um único espécime de Cryptonanus sp. foi identificado entre os itens com base em caracteres dentários. A identificação desse gênero no presente estudo representa o segundo registro no estado do Rio de Janeiro e o sexto no bioma Mata Atlântica, sugerindo que este marsupial ocupa uma ampla faixa ecológica e biogeográfica. O presente estudo destaca a relevância dos pellets de coruja para pesquisas com pequenos mamíferos, mesmo em áreas urbanas e altamente perturbadas.

Abstract Several studies emphasize the use of owl pellets in small mammal inventories in natural areas harboring high richness of rare species, but few Brazilian Atlantic forest localities have been surveyed by this method. The present study documents the species composition and abundance of small mammals in the diet of Tyto furcata in an urban area of the municipality of Campos dos Goytacazes, Rio de Janeiro, Brazil, remarking on a new record of the dwarf mouse opossum genus Cryptonanus in the Atlantic forest. We analyzed 265 pellets regurgitated by a pair of T. furcata from November 2016 to September 2017 found in a nesting box. Analysis of the samples enabled finding a total of 596 individuals of four small mammal species. Mus musculus was predominant among the prey items (98.3%), while the native rodents Necromys lasiurus (1.3%) and Holochilus brasiliensis (0,17%) were much rarer. A single specimen of Cryptonanus sp. was identified among the diet items based on distinctive dental characters. The identification of this genus in the present study represents the second record in the state of Rio de Janeiro, and the sixth in the Atlantic Forest biome, suggesting that this marsupial occupies a wider ecological and biogeographic range. The present study underscores the relevance of owl pellets for small mammal surveys, even in urban and highly disturbed areas.

Resumo Embora atualmente exista um conjunto de estudos sobre aspectos ecológicos de algumas espécies de répteis e de anfíbios que ocorrem nas planícies costeiras arenosas brasileiras (incluindo os chamados habitats de “restinga” e de “campo nativo”), há relativamente poucas informações sobre a composição de espécies geralmente associada a esses ambientes. Durante 31 anos (1988-2019) de estudos herpetológicos realizados em restingas por nossa equipe de pesquisa do Laboratório de Ecologia de Vertebrados (Departamento de Ecologia, Universidade do Estado do Rio de Janeiro, Rio de Janeiro, Brasil) nós estudamos comunidades de répteis e de anfíbios e realizamos diferentes estudos com métodos semelhantes em 70 localidades de dez diferentes Estados ao longo da costa brasileira. Nossas pesquisas resultaram em registros de 87 espécies de répteis (cinco tartarugas, dois crocodilianos, seis anfisbênios, 36 lagartos e 39 serpentes) de 24 famílias, e 77 espécies de anfíbios anuros de nove famílias. Estudamos vários tópicos de história natural sobre anuros e répteis, que resultaram na publicação de alguns estudos ecológicos específicos, especialmente em relação a algumas espécies, abrangendo ecologia populacional e de comunidades, forrageamento e dieta, horário de atividade de espécies, termorregulação, reprodução, uso do microhabitat e parasitismo por ecto e endoparasitas. Nossos resultados ao longo dessas três décadas também contribuíram para a descrição de quatro novas espécies de lagartos (Ameivula nativo, Glaucomastix littoralis, G. abaetensis e G. itabaianensis). Nossos estudos constituem uma importante contribuição para o conhecimento da ecologia de répteis e de anfíbios anuros nesses ecossistemas, bem como para a conservação dos ecossistemas de restinga. A lista de espécies apresentada neste estudo, com base em nossos registros de herpetofauna das planícies costeiras arenosas, fornece para muitas localidades ao longo da costa brasileira o conhecimento necessário sobre a ocorrência de espécies, incluindo a presença de espécies endêmicas e/ ou ameaçadas de extinção, que podem ser úteis para muitas ações de conservação.

Abstract Although currently there is already a set of studies regarding ecological aspects of some particular reptile and amphibian species living in Brazilian sandy coastal plains (including the so-called “restinga” and “campo nativo” habitats), there is comparatively few information on the species composition usually associated to these environments. During 31 years (1988-2019) of herpetological studies carried out in sandy coastal plains environments by our research team of the Laboratory of Vertebrate Ecology (Department of Ecology, Universidade do Estado do Rio de Janeiro, in Rio de Janeiro Brazil) we have surveyed reptile and amphibian communities and performed different studies with similar methods in 70 sites from 10 different states along the Brazilian coast. Our surveys resulted in records of 87 species of reptile (five turtles, two crocodylians, six amphisbaenians, 36 lizards and 39 snakes) from 24 families, and 77 species of anuran amphibians from nine families. We have studied multiple natural history topics for anurans and reptiles which resulted in the publication of some specific ecological studies, especially regarding some species, encompassing population and community ecology, foraging and feeding habits, species activity, thermoregulation, reproduction, use of microhabitats, and parasitism by ecto and endoparasites. Our results along these three decades have also contributed for the description of four new lizard species (Ameivula nativo, Glaucomastix littoralis, G. abaetensis and G. itabaianensis). Our studies constitute an important contribution to the knowledge of the ecology of anuran amphibians and reptiles in these ecosystems, as well as to the conservation of sandy coastal plains environment. The checklist presented in this study, based on our records of sandy coastal plains herpetofauna, provides for many localities along the Brazilian coast, the needed knowledge on species occurrence, including the presence of endemic and/or endangered species, which can be of value for many conservation actions.

ABSTRACT Purpose: Patient-reported history of pads per day (PPD) is widely recognized as a fundamental element of decision-making for anti-incontinence procedures. We hypothesize that SUI severity is often underestimated among men with moderate SUI. We sought to compare patient history of incontinence severity versus objective in-office physical examination findings. Materials and Methods: We retrospectively reviewed our single-surgeon male SUI surgical database from 2007-2019. We excluded patients with incomplete preoperative or postoperative data and those who reported either mild or severe SUI, thus having more straightforward surgical counseling. For men reported to have moderate SUI, we determined the frequency of upgrading SUI severity by recording the results of an in-office standing cough test (SCT) using the Male Stress Incontinence Grading Scale (MSIGS). The correlation of MSIGS with sling success rate was calculated. Failure was defined as >1 PPD usage or need for additional incontinence procedure. Results: Among 233 patients with reported moderate SUI (2-3 PPD), 89 (38%) had MSIGS 3-4 on SCT, indicating severe SUI. Among patients with 2-3 PPD preoperatively, sling success rates were significantly higher for patients with MSIGS 0-2 (76/116, 64%) compared to MSIGS 3-4 (6/18, 33%) (p <0.01). Conclusions: Many men with self-reported history of moderate SUI actually present severe SUI observed on SCT. The SCT is a useful tool to stratify moderate SUI patients to more accurately predict sling success.

We have incorporated rhodamine into polyamide membranes by additive manufacture selective laser sintering technology. Incorporation into 0.5 cm2 membranes was conducted at different pH values and constant temperature of 25 oC. The amounts of incorporated dye were determined by a calibration curve, and analyses showed rhodamine incorporation in the order of 10-6 mol L-1. The absorption spectra of the solutions and membranes after rhodamine incorporation showed maximum absorption at 553 nm and a shoulder at 522 nm, which indicated that a dimer was formed. Photoluminescence presented maximum emission at 575 nm for the sample incorporated with rhodamine in acid pH. The membranes that were treated with acid presented shorter adsorption time and demanded 180 min to reach equilibrium, whereas the non-treated membrane and the membranes that were treated with base required 1440 min to reach equilibrium. Polyamide membrane has proven to be an excellent material for the incorporation of dyes and compounds for application as luminescent sensors.

The objective of this work was to carry out a bibliographic survey of secondary metabolites isolated from the Velloziaceae family, creating a bank of compounds. After the bank was created, four prediction models for potentially active compounds against pathogenic microorganisms (Candida albicans, Escherichia coli, Pseudomonas aeruginosa and Salmonella sp.) were obtained trying to identify which metabolites would be more active against the strains. Four sets of compounds with known activity for microorganisms were selected for the construction of predictive models from the CHEMBL database. Another bank with 163 unique molecules isolated from the Velloziaceae family was built. The Volsurf+ v.1.0.7 software obtained the molecular descriptors and Knime 3.5 generated the in silico model. The performances of the internal and external tests were also analyzed. The study contributed through the virtual screening of a bank of metabolites to select several compounds with potential antimicrobial activity, highlighting the biflavonoid amentoflavone which showed potential activity against the four strains.

Abstract In plant breeding, the dialelic models univariate have aided the selection of parents for hybridization. Multivariate analyses allow combining and associating the multiple pieces of information of the genetic relationships between traits. Therefore, multivariate analyses might refine the discrimination and selection of the parents with greater potential to meet the goals of a plant breeding program. Here, we propose a method of multivariate analysis used for stablishing mega-traits (MTs) in diallel trials. The proposed model is applied in the evaluation of a multi-environment complete diallel trial with 90 F1’s of simple maize hybrids. From a set of 14 traits, we demonstrated how establishing and interpreting MTs with agronomic implication. The diallel analyzes based on mega-traits present an important evolution in statistical procedures since the selection is based on several traits. We believe that the proposed method fills an important gap of plant breeding. In our example, three MTs were established. The first, formed by plant stature-related traits, the second by tassel size-related traits, and the third by grain yield-related traits. Individual and joint diallel analysis using the established MTs allowed identifying the best hybrid combinations for achieving F1’s with lower plant stature, tassel size, and higher grain yield.

ABSTRACT Judicial delays have been the subject of debate in the Brazilian academic community. Among the solutions discussed, jurimetrics has gained ground in seeking quantitative standards in court decisions. However, despite the relevance of this methodology, in Brazil, few researches have been conducted towards its dissemination. Therefore, the present study employs bibliometric techniques on national scientific production, articles, related to the term “jurimetry”, from 2002 to 2019, made available on the Google Scholar search tool, presenting an information panel on the characteristics found in these publications. The results show that in the period surveyed, the number of publications on the subject showed an average annual growth of 18.92%; the collaboration index indicates that there are, on average, 2.32 authors per article, some of which stand out for the number of publications, including Daniel F. N. Menezes (four) and Filipe J. Zabala (three) and, in turn, the most cited authors are Lee Loevinger (eleven citations), Filipe J. Zabala and Fabiano F. Silveira (both with six citations); the magazine that has published the most on the subject is the Revista da Faculdade de Direito of the Federal University of Minas Gerais, with a single magazine publishing four articles, seven magazines publishing two articles and 66 magazines publishing a single article; and finally, as for the keywords associated with the term, the words "adoption", "civil procedure", "invalid act", "illegal act", "partial dissolution", and "successive incidence" stand out, suggesting Civil Law as an area of law more aligned to the use of jurimetry.

RESUMO A morosidade judicial tem sido tema de debates na comunidade acadêmica brasileira. Entre as soluções discutidas, a jurimetria tem ganhado espaço ao buscar por padrões quantitativos nas decisões judiciais. Porém, em que pese a relevância desta metodologia, no Brasil, poucas pesquisas têm sido conduzidas no sentido de sua disseminação. Assim sendo, o presente estudo emprega técnicas de bibliometria sobre a produção científica nacional, artigos, relacionada ao termo “jurimetria”, de 2002 até 2019, disponibilizada na ferramenta de pesquisa do Google Acadêmico, apresentando um painel informativo sobre as características encontradas nestas publicações. Os resultados mostram que no período pesquisado, o número de publicações sobre o tema apresentou um crescimento médio anual de 18,92%; o índice de colaboração indica que existem, em média, 2,32 autores por artigo, sendo que alguns se destacam pelo número de publicações, entre eles, Daniel F. N. Menezes (quatro) e Filipe J. Zabala (três) e, por sua vez, os autores mais citados são Lee Loevinger (onze citações), Filipe J. Zabala e Fabiano F. Silveira (ambos com seis citações); já a revista que mais tem publicado sobre o tema é a Revista da Faculdade de Direito da Universidade Federal de Minas Gerais, sendo que uma única revista publicou quatro artigos, sete revistas dois artigos e 66 revistas um único artigo e, finalmente; quanto às palavras-chaves associadas ao termo, destacam-se as palavras: “adoção”, “processo civil”, “ato inválido”, “ato ilícito”, “dissolução parcial”, e, “incidência sucessiva”, sugerindo o Direito Civil como uma área do direito mais alinhada ao uso da jurimetria.

Abstract Aim: To determine how EMG, anthropometric, and psychological factors, and physical activity levels affect isokinetic peak torque performance (IPT) of multiple set exercise sessions. Methods: 20 participants (27±7 years old), classified as active (A=10) and inactive (I=10), performed 10x10:40secs of maximal unilateral knee flexions and extensions at 120o.s-1. The IPT, EMG, glucose, LDH, and lactate concentrations and perceptions of pain, effort, recovery. Results: Active volunteers showed higher muscularity (52±5 vs 47±4 cm; p<0.05), PTI (262±4 vs 185±4 Nm; p<0.05), relative lower drop in performance (14±2 vs 27±3% ; p<0.05), major MDF (83±1 vs 76±1 Hz; p<0.05), lower log -Fins5 (-12.9±0.3 vs -12.7 ± 0.3 Hz; p<0.05), smaller subjective perception of effort (14.8±0.3 vs 17.0±0.3) and higher subjective perception of recovery (14.2±0.2 vs 12.3±0.3). There was a significant interaction between relative fatigue and the number of sets (F=6.18; p<0.001). Stepwise multiple regressions revealed that subjective perception of recovery best explained the fatigue level generated in the active volunteers [fatigue level= 85.084-5255(SPR)] while for body mass was the best determinant for the inactive group [fatigue level = -21.560 +1.828(BMI)]. Conclusion: Data from the present analysis suggest that physically active individuals show higher torque development and a smaller fatigability index when compared to inactive individuals. Among the fatigue models studied, it is possible that alterations in biochemical components, psychophysiological and EMG are not sensitive to the direct influence of the fatigue dynamics protocol, both in active or inactive individuals.

Lanthanide ions have special light emission, which can occur through descending and ascending energy conversion. Ascending energy conversion is especially interesting for bioapplications because excitation in the infrared region does not excite biomolecules and therefore does not interfere in detection, not to mention that it penetrates deeper in the skin. Here, we synthesized yttrium and aluminum oxide doped with Yb3+and Er3+ions via the non-hydrolytic sol-gel methodology. The doped matrix was incorporated and dispersed over a polyamide membrane obtained by Additive Manufacturing. X-ray diffraction revealed that a mixture of yttrium aluminum monoclinic and garnet phases emerged. Upon excitation at 980 nm in the Yb3+ion, the Er3+ presented more intense emission as a function of the laser power, which favored red emission. The intensities of the bands corresponding to the 4S3/2 → 4I15/2 (563 nm) and 5F9/2 → 4I15/2 (660 nm) transitions involved the absorption of two photons. The oxide incorporated into the polyamide membrane presented the same behavior. After coating with polyetherimide, the latter system was resistant to 5.1 W laser, which paves the way for new applications.
