Avaliação do comportamento de vigas de concreto armado reforçadas à flexão com CFRP quando expostas ao intemperismo de distintas regiões climáticas brasileiras e a degradação acelerada

Gláucia Dalfré
Atualmente, vários trabalhos abordam a aplicação de sistemas de reforço com o uso de FRPs (Fiber Reinforced Polymers) em elementos de concreto armado. Entretanto, a grande maioria dos trabalhos são compostos por ensaios de elementos reforçados logo após a cura do adesivo (a qual ocorre com aproximadamente 14 dias), desprezando-se ou negligenciando-se o comportamento a longo prazo desses sistemas de reforço. Além disso, a maioria dos ensaios são realizados em um único ambiente e não...

The individual-based network structure of palm-seed dispersers is explained by a rainforest gradient

Pâmela Friedemann, Marina Côrtes, Everaldo Castro, Mauro Galetti, Pedro Jordano &
How species interactions change in space and time is a major question in ecology. In tropical forests, plant individuals share mutualistic partners (pollinators or seed dispersers), yet we have little understanding of the factors affecting these individual interaction patterns. We used a seed dispersal individual-based network describing interactions between individuals of a palm species with bird species to investigate how intrinsic and extrinsic characteristics of individual plants influence the network structure. In our work we...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...
