    In order to meet the demand of the tourist activity and to provide quality service in the services, the aim of the project "Walking through the Streets of Desterro - SC" was to offer a patrimonial education activity to city workers through free cultural walks in the Historical Center of Florianópolis, with the intention of comparing and promoting a dialogical interaction of the participants with the city. As an extension project linked to teaching, it provided the improvement of professional practice of students of the technical course in tourism guide, offered by Câmpus Florianópolis Continente of the Federal Institute of Santa Catarina (IFSC),Câmpus Florianópolis Continente. Among the results, it was verified the lack of time and availability of the target public to participate in the walkPara atender a demanda da atividade turística e propiciar qualidade no atendimento nos serviços, o projeto Caminhando pelas Ruas de Desterro - SC teve como objetivo oferecer a atividade de educação patrimonial junto a trabalhadores da cidade através de caminhadas culturais gratuitas no Centro Histórico de Florianópolis, com a intenção de comparar e promover uma interação dialógica dos participantes com a cidade. Por ser um projeto de extensão vinculado ao ensino, teve como um dos seus objetivos; o aprimoramento da prática profissional das discentes do Curso Técnico em Guia de Turismo, ofertado pelo Campus Florianópolis Continente - IFSC. O delineamento metodológico se caracterizou como qualitativa, aplicada descritiva, bibliográfica e a aplicação de um opinário. Dentre os resultados, foi constatado a falta de tempo e disponibilidade do público-alvo em participar da caminhada.DOI: http://dx.doi.org/10.35700/ca.2018.ano5n8.p13-24.228

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050.

    Dentro de las principales características buscadas, las plantas utilizadas como cobertura deben proteger el suelo y mejorar sus propiedades físicas, químicas y biológicas para el cultivo subsecuente. Por tanto, el objetivo de este trabajo fue evaluar el efecto de las cantidades de cobertura y dosis de nitrógeno mineral en las propiedades físicas y en la temperatura del suelo, en el contenido de humedad del suelo y en la producción de frijol durante el ciclo del cultivo, en siembra directa. El ensayo fue implementado mediante un diseño experimental de bloques aleatorios, con tres repeticiones y esquema factorial 3x4. Las dosis de nitrógeno fueron ausencia de N, 50kg·ha-1 y 120kg·ha-1 y las cantidades de cobertura fueron ausencia, 4,0t·ha-1, 6,0t·ha-1 y 10,0t·ha-1. En los tratamientos con aplicación de residuos (4,0; 6,0 y 10,0t·ha-1) hubo mayor sustento en el contenido de agua en el suelo del ciclo del cultivo de fríjol irrigado, comparado con la condición de superficie del suelo descubierto. El tratamiento de 10,0t·ha-1 de residuos de cobertura promovió disminución de la resistencia del suelo a la penetración, aumento en la humedad del suelo y ocasionó menores diferencias de temperatura en el ciclo del cultivo de fríjol irrigado, comparado con el tratamiento testigo. El tratamiento de 10,0t·ha-1 de residuo y 120kg·ha-1 de nitrógeno proporcionó la mayor producción de fríjol.Plant residues employed as mulching material are one of the main factors that contribute to the improvement of the physical, chemical and biological soil proprieties for subsequent crops. Therefore, the objective of this study was to evaluate the effect of the combination of different amounts of residues and mineral nitrogen on soil physical attributes, soil temperature, soil water content and grain yield during the whole cycle of a bean crop under the no-tillage system. The experiments were organized in randomized blocks with three replications using a 3x4 factorial design. The nitrogen levels were zero, 50kg·ha-1 and 120kg·ha-1 and the straw mulch amounts were zero, 4.0t·ha-1, 6.0t·ha-1 and 10.0t·ha-1. The treatments that received residues applications presented greater maintenance of soil water content throughout the whole cultivation cycle when compared to the soil without mulching. The treatment of 10.0t·ha-1 amount of mulching on the surface promoted reduction in the soil penetration resistance, increase in the soil water content and minor differences of temperature throughout the cycle of the culture. The treatment of 10,0t·ha-1 of residues and nitrogen promoted an increase in the yield of beans

Laboratório Interdisciplinar de Pesquisas Médicas. Rio de Janeiro, RJ. Brasil.In the large Zika virus (ZIKV) epidemic that occurred in Brazil in 2015, the intrauterine fetal exposure to ZIKV was associated with a significant risk of developing microcephaly and neurological disorders in the infected infants. ZIKV-associated disease has since been reported in 24 countries in the Americas. At present, definitive evidence is lacking regarding the intrauterine co-exposure to ZIKV and other viral infections and whether the coinfection impacts the risk of acquiring either infection or disease severity. Here, we provide evidence of intrauterine exposure to both ZIKV and human immunodeficiency virus (HIV) infections, causing congenital Zika syndrome in an HIV-exposed uninfected infant. Clinical, imaging and laboratory examinations of the pregnant woman and the newborn were performed. Histopathology, ZIKV/HIV-specific immunoassays, and ultrastructural evaluation of the placenta were performed. The Zika-asymptomatic, HIV-positive pregnant woman underwent ultrasounds revealing fetal cerebral ventriculomegaly, microcephaly, and brain atrophy. Her baby girl was born small for gestational age and with the neurological sequelae of congenital Zika syndrome. The evaluation of the abnormally large term placenta revealed severe damage to the maternal decidua and chorionic villi, cells positive for ZIKV-specific antigens but not for HIV antigens, and intracellular membranous clusters of virus-like particles approximately 25 nm in diameter. The rapid progression and severity of the congenital Zika syndrome may be related to the uncontrolled HIV disease in the mother. The poor inflammatory response observed in the placenta may have reduced the inherent risk of mother-to-child transmission of HIV
