1. Estudo do desempenho do processo de microfiltração tangencial com membranas cerâmicas aplicado à retenção de bactérias e redução de sólidos suspensos de uma bebida à base de açaí / Performance study of the crossflow microfiltration process with ceramic membranes applied to the bacteria retention and suspended solids reduction of the beverage based on açai
In this doctoral research, the crossflow microfiltration process utilizing ceramic membranes was investigated aiming at the bacteria retention (Escherichia coli) and reduction of suspended solids of beverage based on açai (Euterpe oleracea Mart.). The selected commercial membranes of alfa-alumina (AL IND.2O IND.3) had nominal pore sizes of 0.8 and 1.2 müm

2. A study of the porosity of gas filtration cakes
The purpose of this work was to determine the porosity of gas filtration cakes composed of powdery organic and inorganic materials, employing a technique whereby an optical microscope generates images of the powdery layer deposited on the surface of the filtering medium. To this end, experimental cake filtration porosity data were obtained as a function of t

3. Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes.
The particle retention inside a filter medium, after cleaning, significantly improves the initial pressure drop during the subsequent cycle, that is, the residual pressure drop. However, the way as these particles accommodate inside the filter isnt still very clear, as well as, its impact on filtering performance. This work aims to verify the spatial disposa

4. Modificação quimica da borracha natural pela tecnica de polimerização em emulsão poe semente : propriedades coloidais, estrutura quimica e comportamento viscoelastico
The chemical modification of natural rubber (NR) by grafting of copolymers in the backbone of the hydrophobic substrate, poly-cis-isoprene, by free radical polymerization, using a seeded emulsion polymerization system, has been demonstrated. Two copolymers were grafted, a hydrophilic of dimethylaminoethylmethacrylate (DMAEMA) or a hydrophobic of methyl metha

5. Effect of Inoculation Techniques and Relative Humidity on the Growth of Molds on the Surfaces of Yellow Layer Cakes
Four inoculation techniques were compared for initiation of growth on cake surfaces: spot, air cabinet, spray (atomizer), and talc addition methods. Molds were isolated from commercial cakes and were identified as Aspergillus sydowii, Aspergillus ochraceus, Penicillium funiculosum, and Eurotium herbariorum. Cake surfaces were inoculated with mold spores and

6. Heat and mass transfer scale-up issues during freeze drying: II. Control and characterization of the degree of supercooling
This study aims to investigate the effect of the ice nucleation temperature on the primary drying process using an ice fog technique for temperature-controlled nucleation. In order to facilitate scale up of the freeze-drying process, this research seeks to find a correlation of the product resistance and the degree of supercooling with the specific surface a
