Resposta fisiológica à infestação experimental com Ichthyophthirius multifiliis (Fouquet, 1876) em alevinos de jundiá (Rhamdia quelen Quoy e Gaimard, 1824) previamente alimentados com diferentes fontes lipídicas

Feeding activity and influence of intraspecific competition on zooplankton communities by jundiá (Rhamdia quelen Quoy and Gaimard, 1824) in laboratory.

Experiments were designed to determine if the juvenile forms of jundia (Rhamdia quelen) exhibit selectivity feeding on zooplanktonic organisms and the influence of intraspecific competition on the diet. The fish were maintained in 5000-L containers, and after seven days from birth, they were acclimated in experimental units with different densities and supplied with water containing plankton (n...

Developing Strategies for the Control of Ichthyophthirius Multifiliis Fouquet , 1876 ( Ciliophora )

Life cycle and settlement of an Australian isolate of Ichthyophthirius multifiliis Fouquet, 1876 from rainbow trout.

Ichthyophthirius multifiliis Fouquet, 1876, a ciliate parasite, is a cosmopolitan and problematic parasite of cultured freshwater fish. Each geographical isolate of I. multifiliis has variations in life cycle timing under different abiotic water conditions, such as temperature and salinity. We assessed the effects of salinity and temperature on the development and the preferred settlement site ...

Qualidade afetiva em sistemas computacionais: design de interação para e com crianças em contexto de aprendizado

As tecnologias digitais cada vez mais fazem parte do nosso cotidiano, estando presentes em todos os lugares. As abordagens tradicionais de design faziam sentido quando a computação era direcionada e centrada em atividades bem específicas. As bases que designers antes seguiam para direcionar seus esforços tinham por referência os conceitos de usabilidade e acessibilidade. Mais recentemente, esse...

Disseminacao de mensagens DTN com base em grupos de interesses

Recent works explore social characteristics of nodes to improve message delivery rate in Delay Tolerant Networks (DTN). This work uses machine learning techniques to create node groups organized by common interests. Messages are sent to target groups, and from there to the final destination. Simulation results using The ONE simulator show that the larger the group size the higher the message de...
