Encapsulação da rifampicina em matrizes poliméricas flutuantes obtidas por liofilização a partir de metilcelulose e ftalato de hidroxipropilmetilcelulose. Avaliação da liberação in vitro
(2001-12-01)
Floating multiparticles for oral administration with different compositions were studied from a matricial polymeric system to obtain sustained release. The polymers used in the multiparticles constitution were methylceullose ...
An interpretation of langmuir probe floating voltage signals in a cutting arc
(Institute of Electrical and Electronics Engineers, 2009-12)
An experimental study of the electrostatic probe floating voltage signals in a cutting arc and its physical interpretation in terms of the arc plasma structure is reported. Sweeping electrostatic probes have been used to ...
Real-time physical engine for floating objects with two-way fluid-structure coupling
(IDOSI, 2013-06)
A method to simulate graphic animations of objects floating in a water surface in real time is presented. The fluid is simulated by means of the Lattice Boltzmann method for the shallow-waters equations, and the movement ...
Temporal and spatial patterns of macroinvertebrates associated with small and medium-sized free-floating plants
(Springer, 2013-02)
Macrophytes play an important role in structuring communities in aquatic ecosystems due to their influence on ecological processes and attributes of biological aquatic assemblages. Freshwater macroinvertebrates comprise a ...
Chemical repellency and adverse effects of free-floating macrophytes on the cladoceran Ceriodaphnia dubia under two temperature levels
(Springer Tokyo, 2013-06)
Macrophytes can structure biological assemblages in subtropical lakes. Zooplankton often uses them as a refuge, but in the absence of predators many species frequently avoid them. It is hypothesized that plant exudates can ...
Governança corporativa e a relação com desempenho e o valor das empresas brasileiras
(Universidade do Vale do Rio dos Sinos, 2012-05-17)
Corporate governance can be understood as a set of incentive and controls mechanisms, internal and external, which aim to minimize the costs of the problems arising from the agency. The issue is important because it is ...

The structuring role of free-floating plants on the fish community in a tropical shallow lake: an experimental approach with natural and artificial plants
(2016-09-01)
Free-floating plants are important components of aquatic ecosystems in tropical climates, playing a key role in the structure and spatial distribution of fish communities. This study aims at elucidating the potential effects ...
