1. Remoção de óleo da água de produção por flotação em coluna utilizando tensoativos de origem vegetal
Na indústria petrolífera, a água está associada ao petróleo e ao gás natural, formando a água de produção e gerando um grande impacto ambiental. Existem diversos métodos de tratamento para as águas oleosas, tais como: vasos gravitacionais, sistemas de filtração em meio granular, flotação, centrifugação e utilização de hidrociclones, podend

2. The Cohesive Population Genetics of Molecular Drive
The long-term population genetics of multigene families is influenced by several biased and unbiased mechanisms of nonreciprocal exchanges (gene conversion, unequal exchanges, transposition) between member genes, often distributed on several chromosomes. These mechanisms cause fluctuations in the copy number of variant genes in an individual and lead to a gr

3. Diffusion of injected macromolecules within the cytoplasm of living cells.
The diffusion of macromolecules introduced into the cytoplasm of human fibroblasts by erythrocyte-mediated microinjection was measured by the fluorescence recovery after photobleaching technique. The apparent diffusion coefficients for fluorescein-labeled IgG and fluorescein-labeled bovine serum albumin were approximately 10(-8) cm2/sec at 22 degrees C, cons

4. Specific antibody-dependent interactions between macrophages and lipid haptens in planar lipid monolayers.
The binding of guinea pig peritoneal macrophages to planar lipid monolayers on alkylated glass is shown to be highly specific, requiring lipid hapten in the monolayer and specific anti-hapten IgG antibody. This is true for both "fluid" and "solid" monolayer membranes, in which the lateral diffusion coefficients of fluorescent lipid probes and bound fluoresce
