ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Abstract Leadership theories developed since the beginning of the last century primarily represent positivist premises, strongly marked by the separation between subject and object, dichotomization, objectivism, quantification, reproduction, and validation. Based on this, we argue that the field needs epistemological approaches that challenge the mainstream of leadership studies. To this end, phenomenology can ground the possibility of understanding leadership as a world phenomenon. In theoretical terms, phenomenology is a return to the acts through which we gain knowledge of objects, thus the proposal to return to the things themselves. This article analyzes the contributions of phenomenology to leadership studies. In order to interact with such identified gaps in leadership studies, we explore the rescue of the lifeworld in the face of objectivism, the reconciliation between subject and object, the attribution of meanings, the epoché, and the change of positioning.

Resumen Las teorías del liderazgo que se han desarrollado desde principios del siglo pasado representan, en su mayoría, premisas positivistas, fuertemente marcadas por la separación entre sujeto y objeto, dicotomización, objetivismo, cuantificación, reproducción y validación. A partir de esto, argumentamos que el campo carece de enfoques epistemológicos que desafíen la corriente principal de los estudios de liderazgo. Para ello, la fenomenología puede sustentar la posibilidad de entender el liderazgo como un fenómeno en el mundo. En términos teóricos, la fenomenología es una vuelta a los actos a través de los cuales se conocen los objetos, de ahí la propuesta de volver a las cosas mismas. Así, el objetivo de este artículo es analizar las contribuciones de la fenomenología a los estudios de liderazgo. Por tanto, para interactuar con tales vacíos identificados en el campo de los estudios de liderazgo, exploramos el rescate del mundo de la vida frente al objetivismo; la reconciliación entre sujeto y objeto, atribución de significados; la epoché y el cambio de posición.

Resumo As teorias de liderança que vêm sendo desenvolvidas desde o início do século passado representam, em sua maioria, premissas positivistas, fortemente marcadas pela separação entre sujeito e objeto, dicotomização, objetivismo, quantificação, reprodução, validação. Com base nisso, argumentamos que o campo carece de abordagens epistemológicas que desafiem o mainstream dos estudos de liderança. Nesse intuito, a fenomenologia pode fundamentar a possibilidade para o entendimento da liderança enquanto um fenômeno no mundo. Em termos teóricos, a fenomenologia é um retorno aos atos por meio dos quais se tem conhecimento dos objetos: por isso a proposta de se voltar às coisas mesmas. Desse modo, o objetivo deste artigo é analisar as contribuições da fenomenologia para os estudos em liderança. Para tanto, de modo a interagir com tais lacunas identificadas no campo de estudos de liderança, exploramos o resgate do mundo-da-vida frente ao objetivismo; à reconciliação entre sujeito e objeto; à atribuição de sentidos; à epoché e à mudança de posicionamento.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Objective to understand obstetrical nursing identity in the area of its performance in a Birth Center. Method a descriptive-exploratory study with a qualitative approach. Semi-structured interviews were carried out between March and August 2022 with 09 nurse-midwives from the Centro de Parto Normal Haydeê Pereira Sena, Pará, Brazil. Content analysis and discussion based on Claude Dubar’s identity were used. Results two categories emerged: Professional identity: a matter of social construction, which portrays the social scope of identity construction through experiences as a student and as a nurse and their relationships in the work process; and The identity of obstetrical nursing in the field of its performance in a Birth Center, favoring humanization, scientific evidence for women’s autonomy, which is only provided by the birth center’s structuring policy, and coping with other professional classes, to guarantee and legitimize nurse-midwives’ work. Conclusion and implications for practice understanding nurses’ professional identity in the birth center is the central point to ensure their appreciation and their performance with respect, legitimizing their right, because, with a solid identity, greater quality and changes in the hegemonic obstetric model are guaranteed.

ABSTRACT. The objective of this study was to evaluate the the ability of foliar application of potassium nitrate (KNO3) to induce water deficit tolerance in sorghum plants (Sorghum bicolor cv. P898012) subjected to water deficit at pre-flowering. The experiment was conducted under greenhouse conditions with 4 treatments: field capacity (FC), water deficit (WD), field capacity + KNO3 (FC + KNO3), and water deficit + KNO3 (WD + KNO3). Two foliar applications of 3% (m/v) KNO3 were made, the first on day zero of stress and the second on the fifth day. All analyses were performed after 12 days of stress (end of stress). Foliar application of KNO3 to irrigated plants led to increases in relative chlorophyll content, photosynthetic rate, stomatal conductance, transpiration, and carboxylation efficiency. It also induced increases in leaf concentrations of P, Mg, S, Cu, and Fe, in addition to height growth. Under water deficit conditions, plants treated with KNO3 presented higher relative chlorophyll content, leaf area, photosynthetic rate, stomatal conductance, transpiration, carboxylation efficiency, and higher levels of P, K, Mg, S, Cu, and Fe than those not treated with KNO3. The morphometry of the root system was not altered by the treatments. In addition, plants treated with KNO3 under water deficit conditions showed higher growth and a grain yield 32.2% higher than those that did not receive KNO3. These results demonstrated that KNO3 applied to the leaves induced water deficit tolerance in sorghum plants subjected to severe water stress at pre-flowering.

RESUMO Objetivos: compreender a percepção das mulheres quanto à assistência recebida durante o parto e nascimento. Métodos: estudo descritivo-exploratório, qualitativo, realizado com 54 puérperas de hospitais da Região Metropolitana II do estado do Rio de Janeiro, de janeiro a dezembro de 2018, utilizando entrevistas semiestruturadas submetidas à análise de conteúdo. Resultados: as percepções das puérperas sobre a assistência ao parto recebida apontaram a utilização de intervenções, tais como manobras de pressão sobre o fundo uterino no período expulsivo - manobra de Kristeller, episiotomia e toque vaginal repetidos e sem consentimento. A utilização de rotinas institucionais, como a dieta zero, parto horizontal e desrespeito. Considerações Finais: apesar do incentivo das políticas públicas de humanização, o modelo tecnocrático ainda se faz presente na assistência obstétrica ao parto. A humanização da assistência obstétrica requer mudanças de atitudes e paradigmas assistenciais, a fim de garantir respeito e direito à assistência de qualidade.

ABSTRACT Objectives: to understand women’s perception regarding the care received during labor and birth. Methods: this is a descriptive-exploratory, qualitative study carried out with 54 postpartum women from hospitals in the Metropolitan Region II of the state of Rio de Janeiro, from January to December 2018, using semi-structured interviews submitted to content analysis. Results: puerperal women’s perceptions about the childbirth care they received indicated the use of interventions, such as pressure maneuvers on the uterine fundus during the expulsion period - Kristeller maneuver, episiotomy and repeated vaginal examination and without consent. The use of institutional routines, such as zero diet, horizontal birth and disrespect. Final Considerations: despite the encouragement of public humanization policies, the technocratic model is still present in obstetric care during childbirth. The humanization of obstetric care requires changes in attitudes and care paradigms, in order to guarantee respect and the right to quality care.

ABSTRACT This work analyzed different logistics structures under a sustainable perspective. It wasdeveloped a discrete event simulation model associated with optimization algorithm to evaluate the best combinations of the model. Besides, the comparison between the simulation optimization and a multicriteria method was performed. The simulation software Ururau, in which a model with optimization algorithm allowed testing different variables, was applied in order to find the best answer to the issue. Results showed that a connection of direct proportionality between variables of transport time, greenhouse gas emissions and lead time can happen. It was also checked that the solution returned by the simulation optimization was similar to the multicriteria method in most of the tests. The ones that differed were due to smallmathematical precisions between the methods.

PURPOSE:To investigate the osseointegration properties of prototyped implants with tridimensionally interconnected pores made of the Ti6Al4V alloy and the influence of a thin calcium phosphate coating.METHODS: Bilateral critical size calvarial defects were created in thirty Wistar rats and filled with coated and uncoated implants in a randomized fashion. The animals were kept for 15, 45 and 90 days. Implant mechanical integration was evaluated with a push-out test. Bone-implant interface was analyzed using scanning electron microscopy.RESULTS: The maximum force to produce initial displacement of the implants increased during the study period, reaching values around 100N for both types of implants. Intimate contact between bone and implant was present, with progressive bone growth into the pores. No significant differences were seen between coated and uncoated implants.CONCLUSION:Adequate osseointegration can be achieved in calvarial reconstructions using prototyped Ti6Al4V Implants with the described characteristics of surface and porosity.

Purpose To ensure patient safety and surgical efficiency, much emphasis has been placed on the training of laparoscopic skills using virtual reality simulators. The purpose of this study was to determine whether laparoscopic skills can be objectively quantified by measuring specific skill parameters during training in a virtual reality surgical simulator (VRSS). Materials and Methods Ten medical students (with no laparoscopic experience) and ten urology residents (PGY3-5 with limited laparoscopic experience) were recruited to participate in a ten-week training course in basic laparoscopic skills (camera, cutting, peg transfer and clipping skills) on a VRSS. Data were collected from the training sessions. The time that individuals took to complete each task and the errors that they made were analyzed independently. Results The mean time that individuals took to complete tasks was significantly different between the groups (p < 0.05), with the residents being faster than the medical students. The residents' group also completed the tasks with fewer errors. The majority of the subjects in both groups exhibited a significant improvement in their task completion time and error rate. Conclusion The findings in this study demonstrate that laparoscopic skills can be objectively measured in a VRSS based on quantified skill parameters, including the time spent to complete skill tasks and the associated error rate. We conclude that a VRSS is a feasible tool for training and assessing basic laparoscopic skills.

O trabalho avaliou a interação entre temperaturas do solo (13ºC, 15ºC, 17ºC e 19ºC), profundidades de semeadura (2,5; 5,0 e 7,5 cm) e tratamento de semente com fungicida (captan + tiabendazole) na emergência de plantas de milho. Utilizaram-se sementes do híbrido AS 1565 com 22% de incidência de Fusarium verticillioides e solo de lavoura naturalmente infestado. O ensaio foi conduzido em câmaras climatizadas por 25 dias, com contagem diária da emergência. Houve diferença significativa entre sementes tratadas e não tratadas, sendo que quanto menor a temperatura do solo e maior a profundidade de semeadura, maior a resposta ao tratamento de sementes na emergência de plantas. A estabilidade de emergência ocorreu aos 23, 18, 12 e 12 dias após a semeadura respectivamente para 13ºC, 15ºC, 17ºC e 19ºC, mostrando redução na velocidade de emergência nas temperaturas baixas.

In this study the interaction between soil temperatures (13ºC, 15ºC, 17ºC and 19ºC), depths of sowing (2.5, 5.0 and 7.5 cm) and seed treatment with fungicide (captan + thiabendazol) in the emergence of plants maize was evaluate. Seed of hybrid corn AS1565 with 22% of the incidence of Fusarium verticillioides was used and soil naturally infested. The trays were kept in conditioned chambers for 25 days, measured daily the emergence. There was significance difference between treated and untreated seeds. According to lower soil temperature and higher the depth of seedling, was largest the response of the seed treatment in the plants emergence. The emergence of plants was measured daily to obtain the stability, which occurred at 23, 18, 12 and 12 days after seedling at temperatures of 13ºC, 15ºC, 17ºC and 19ºC respectively, showing reduction in the emergence speed at low temperatures.

O objetivo desse trabalho foi avaliar a eficiência da seleção em uma população de maracujazeiro amarelo no segundo ciclo de seleção recorrente, com base em informações agronômicas e moleculares. Foram utilizadas 39 progênies de irmãos-completos, avaliadas para 11 características agronômicas e genotipadas por meio de marcadores microssatélites. As progênies foram selecionadas com base na matriz de distância genética e a eficiência da seleção foi verificada por meio das médias das características agronômicas de maior importância para a cultura. Das 25 melhores progênies selecionadas, apenas 12 foram comuns às três estratégias de seleção (agronômica, molecular e seleção combinada). Não foi observada correlação significativa entre as matrizes de distância genética com base nos dados agronômicos x moleculares. As progênies selecionadas pelos marcadores moleculares apresentaram maiores médias para produtividade e número de frutos. Os resultados indicam a possibilidade de aplicação deste procedimento de seleção combinada com base em dados agronômicos e moleculares para otimizar os ganhos genéticos para os caracteres sob seleção.

The purpose of this study was to evaluate the efficiency of selection of a population of yellow passion fruit in the second cycle of recurrent selection, based on molecular and agronomic data. In 39 full-sib progenies, genotyped using microsatellite markers, 11 agronomic traits were evaluated. The progenies were selected based on the genetic distance matrix and the selection efficiency was confirmed based on the most important agronomic traits of yellow passion fruit. Only 12 of the 25 best progenies were identified by all three selection strategies (agronomic, molecular and combined selection). No significant correlation was observed between the genetic distance matrices and the molecular x agronomic data. The progenies selected by molecular markers had the highest mean yield and fruit number. Results indicate the possibility of applying this combined selection procedure based on agronomic as well as molecular data to optimize genetic gain for the traits under selection.

JUSTIFICATIVA E OBJETIVOS: A dor é fator agravante da morbimortalidade pós-operatória, principalmente nas intervenções de grande porte. Métodos para combatê-la eficazmente esbarram em custo elevado e por isso não são acessíveis em todos os serviços. A opção seria a utilização de um opioide com meia-vida longa como a metadona. O objetivo deste trabalho foi comparar a demanda de analgesia pós-operatória em pacientes que receberam, na indução de anestesia, metadona ou morfina, ou ainda placebo, além da prevalência de náuseas e vômitos no pós-operatório. MÉTODO: 55 pacientes programados para cirurgia cardíaca foram divididos em três grupos que receberam, na indução da anestesia, 20 mg de metadona, ou 20 mg de morfina, ou ainda placebo. Ao término, eram encaminhados à UTI, onde foram avaliados os seguintes fatores: duração da anestesia, tempo até a extubação, tempo até a necessidade do primeiro analgésico, número de doses necessárias em 24 horas, avaliação da analgesia pelo paciente e prevalência de náuseas/vômitos. RESULTADOS: Não houve diferença na duração da anestesia e no prazo até a extubação. A primeira dose de analgésico naqueles que receberam metadona foi administrada mais tarde que nos outros dois grupos. A necessidade de analgésicos no grupo metadona foi menor, a qualidade da analgesia foi melhor e a prevalência de náuseas e vômitos, também menor. CONCLUSÕES: A metadona na indução da anestesia mostrou-se eficiente para a analgesia em cirurgias de grande porte. Houve menor incidência de náuseas e vômitos, tratando-se, portanto, de uma opção de baixo custo, disponível em nosso meio e que deve ser estimulada.

BACKGROUND AND OBJECTIVES: Pain is an aggravating factor in postoperative morbidity and mortality especially in large size surgeries. Methods to effectively fend pain collide with elevated costs and for this reason they are not accessible in every service. The option would be the use of an opioid with long half-life, such as methadone. The objective of the present study was to compare the requirements of postoperative analgesia in patients who received methadone, morphine, or placebo during anesthetic induction, besides the prevalence of postoperative nausea and vomiting. METHODS: Fifty-five patients scheduled for cardiac surgery were divided into three groups and they received during anesthetic induction 20 mg of methadone, 20 mg of morphine, or placebo. At the end of surgery, patients were transferred to the ICU where the following parameters were evaluated: duration of anesthesia, time until extubation, time until the need of the first analgesic, number of doses required in 24 hours, assessment of analgesia by the patient, and prevalence of nausea/vomiting. RESULTS: Differences in the duration of anesthesia and time until extubation were not observed. The first dose of analgesic in patients who received methadone was administered later than in patients in the other two groups. The need of analgesics in the methadone group was lower, quality of analgesia was better, and prevalence of nausea and vomiting was also lower. CONCLUSIONS: Methadone during anesthetic induction was effective for analgesia in large size surgeries. Lower incidence of nausea and vomiting was observed in the methadone group and therefore it is a low cost option available among us that should be stimulated.

JUSTIFICATIVA Y OBJETIVOS: El dolor es un factor agravante de la morbimortalidad postoperatoria, principalmente en las intervenciones de gran porte. Los métodos para hacerle frente eficazmente se topan con los costes elevados y por eso no son accesibles a todos los servicios. La opción sería la utilización de un opioide con vida media larga como la metadona. El objetivo de este trabajo, fue comparar la demanda de la analgesia postoperatoria en pacientes que recibieron en la inducción de anestesia, metadona o morfina, o incluso placebo, además de la prevalencia de náuseas y vómitos en el postoperatorio. MÉTODO: Cincuenta y cinco pacientes programados para la cirugía cardíaca fueron divididos en tres grupos que recibieron en la inducción de la anestesia, 20 mg de metadona, o 20 mg de morfina, o incluso placebo. Al finalizar, fueron derivados a la UCI, donde se evaluaron los siguientes factores: duración de la anestesia, tiempo hasta la desentubación, tiempo hasta la necesidad del primer analgésico, número de dosis necesarias en 24 horas, evaluación de la analgesia por el paciente y prevalencia de náuseas/vómitos. RESULTADOS: No hubo ninguna diferencia en la duración de la anestesia y en el plazo hasta la desentubación. La primera dosis de analgésico en aquellas que recibieron metadona fue administrada más tarde que en los otros dos grupos. La necesidad de analgésicos en el grupo metadona fue menor, la calidad de la analgesia fue mejor y la prevalencia de náuseas y vómitos, también fue menor. CONCLUSIONES: La metadona en la inducción de la anestesia fue eficiente para la analgesia en las cirugías de gran porte. Hubo un menor aparecimiento de náuseas y vómitos, tratándose, por tanto, de una opción de bajo coste, disponible en nuestro medio y que debe ser estimulada.

O objetivo deste trabalho foi estimar a variabilidade genética em dois ciclos de seleção recorrente do maracujazeiro-amarelo (Passiflora edulis) e avaliar o impacto da seleção nas progênies selecionadas via alterações nas frequências alélicas, detectadas com uso de marcadores microssatélites. Vinte e três pares de iniciadores microssatélites foram utilizados na genotipagem de 66 progênies de irmãos completos. Estimaram-se a frequência alélica, heterozigosidade esperada (He) e observada (Ho), conteúdo de informação polimórfica (PIC) e coeficiente de endogamia (f). Foram encontrados 32 alelos nas populações, dos quais apenas dois foram perdidos durante a seleção. O número médio de alelos por locos foi de 2,46, no primeiro ciclo, e de 2,30 no segundo ciclo. As diferenças nas frequências alélicas nos dois ciclos de seleção recorrente não foram significativas. A He média no primeiro ciclo de seleção foi de 0,20 por loco, ligeiramente maior que a Ho (0,15). No segundo ciclo de seleção, o valor médio da Ho foi menor que o da He, com média de 0,12. Os valores médios de f aumentaram no segundo ciclo seletivo, de 0,26 para 0,32. A maioria dos locos apresentou valores negativos de f, o que sugere altos índices de heterozigosidade. O valor médio do PIC decresceu de 0,18 para 0,16 no segundo ciclo. Houve pequena perda de variabilidade e alterações nas frequências alélicas; porém, esta oscilação pode ser considerada normal quando se pratica seleção.

The objective of this work was to estimate the genetic variability in two recurrent selection cycles of the yellow passion flower (Passiflora edulis), and to evaluate the impact of selection on the progenies selected via changes in allele frequency, detected by microsatellite markers. Twenty-three microsatellites were used for genotyping 66 full-siblings. Allele frequency, expected (He) and observed (Ho) heterozygosity, polymorphic information content (PIC) and inbreeding coefficient (f) were estimated. Thirty-two alleles were found in these populations, of which only two were lost during selection. The average number of alleles per locus was 2.46 in the first cycle, and 2.30 in the second. The differences in allele frequencies in the two cycles were not significant. The mean He in the first cycle was 0.20 per locus, slightly higher than Ho (0.15). In the second selection cycle, the mean value of Ho was lower than of He, with an average of 0.12. The mean values of f increased in the second selection cycle, from 0.26 to 0.32. Most of the loci showed negative values of f, which suggests high levels of heterozygosity. The mean value of PIC decreased from 0.18 to 0.16 in the second cycle. There were small losses of variability and changes in allele frequencies; however, these variations can be considered normal when selection is practiced.

Abstract: En | Text: En | PDF: En

This paper deals with the post fire behavior of hybrid nanocomposites under dynamic loadings. A series of tests were performed to investigate how nanoparticles (i.e. nanoclay and graphene nanosheets) affect the post-fire overall composite behavior. Carbon fiber/epoxy-nanoclay and carbon fiber/epoxy-graphene nanosheets were manufactured. The nanoparticles employed were Cloisite 30B nanoclay, and surface modified graphene nanosheets. The epoxy system used was RemLam M/HY956. The nanocomposites were made using ultrasonic mixer for nanoparticle dispersion in acetone followed by a shear mixing of acetone/nanoparticle/hardener. The following steps involved degassing, the addition of resin to the mixture and, the hand lay-up with vacuum assisted cure. Thermo gravimetric analysis (TGA) indicates an average decrease on peak mass loss around 41% with the addition of small amount of nanoparticles. The sample plates were exposed to a heat flux of 800 kW.m-2 for a period up to 120 seconds. The post-fire low velocity impact tests indicated the impact resistance degraded as a function of heat exposure. However, the addition of nanoclay leads to an increase on impact peak force of 11.69%. The carbon oxidation could be the main cause of the increase on impact peak load is lower than expected, only 6.72%. The model predictions are overestimated by approximately 8%. Even though, it can be a good tool for composites design.

Os carrapatos são susceptíveis à infecção por nematoides entomopatogênicos. Essa susceptibilidade diverge quanto às espécies de carrapato estudadas, à fase evolutiva, às espécies e estirpes dos nematoides e ao tempo ao qual os carrapatos ficam expostos a estes. O presente trabalho teve como objetivo avaliar os tempos de infecção in vitro de fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus pelo nematoide entomopatogênico Steinernema glaseri estirpe CCA, pela análise dos parâmetros biológicos do carrapato. Os resultados obtidos demonstraram que um período de duas horas de exposição foi suficiente para que fêmeas ingurgitadas de R. microplus fossem infectadas por S. glaseri CCA e que um período de exposição mínimo de 24h foi necessário para que houvesse infecção de fêmeas ingurgitadas de R. microplus por S. glaseri estirpe CCA, capaz de gerar, in vitro, eficácia no tratamento superior a 90%.

Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes species and strains and the time the ticks are exposed to them. Usually this period ranges from 24 to 72 hours. The aim of this study was to evaluate the infection times in vitro of engorged Rhipicephalus (Boophilus) microplus females by the entomopathogenic nematodes Steinernema glaseri CCA strain, by analysis of the ticks' biological parameters. The results show that a 2-hour exposure time was sufficient for the engorged R. microplus females to be infected by S. glaseri CCA, but that a minimum exposure time of 24 hours was necessary to generate treatment efficacy above 90%.
