1. Pós-tratamento de efluente têxtil usando coagulação/floculação combinado com processos de separação por membranas
The textile industry uses large volumes of water in their processes, especially in the dyeing step, which are also used large quantities of coloring agents and textile auxiliaries. The presence of these products in the effluent generates a harmful effect and clearly visible to the environment because they cause changes in the parameters of the receiving body

2. Estudos de simulação computacional do processo de redução de UF4 a Urânio metálico / computational simulation studies of the reduction process of UF4 to metallic uranium
The production of metallic uranium is essential for production of fuel elements for using in nuclear reactors manufacturing of radioisotopes and radiopharmaceuticals. In IPEN, metallic uranium is produced by magnesiothermical reduction of UF4. This reaction is performed in a closed graphite crucible inserted in a sealed metal reactor and no contact with the

3. AvaliaÃÃo dos efeitos renais da fraÃÃo L-aminoÃcido Oxidase isolada do veneno da serpente Bothrops marajoensis. / Assessment of renal effects of L-amino acid oxidase fraction isolated from snake Bothrops marajoensis venom.
There are about 3.000 species of snakes worldwide, but only 10 to 14% are venomous. Among South American countries, Brazil is the one with the largest number of accidents, with approximately 20.000 snakebites each year. According to the Department of Health of Brazil, the genus Bothrops are the main involved in snakebites in the country. Acute renal failure

4. Estudo dos efeitos renais do veneno da serpente Lachesis muta muta. / Study of renal effects of Lachesis muta muta venom.
The accident caused by the snake Lachesis muta muta is serious and its venom is responsible for many systemic changes, such as hypotension. In this work, the renal effects of the total venom of this snake in the renal perfusion system and in cultured renal tubular cells of the type MDCK (Madin-Darby Canine Kidney) are investigated. Isolated kidneys from Wist

5. Produção de agua de coco (cocus nucifera) utilizando membranas de micro e ultrafiltração de celulose, PES e PVDF / Coconut water processing using micro and ultrafiltration membranes of cellulose, PES and PVDF
Coconut water is a natural drink. Lately, its consumption has been growing in both natural form and processed form, because of the coconut water health benefits. Processing methods are used, essentially, to inhibit the enzymes actions (polyphenoloxidase and peroxidase) that are responsible for coconut water color chage to rose and ensure its microbiological

6. Low ethanol consumption increases insulin sensitivity in Wistar rats
Several human studies suggest that light-to-moderate alcohol consumption is associated with enhanced insulin sensitivity, but these studies are not free of conflicting results. To determine if ethanol-enhanced insulin sensitivity could be demonstrated in an animal model, male Wistar rats were fed a standard chow diet and received drinking water without (cont

7. Ultrafiltration of cheese whey from fresh pre-mines treaty and microfiltered: effects of the flow volume and pressure in the transmembrane flow of permeate / Ultrafiltração do soro de queijo minas frescal pre-tratado e microfiltrado : efeitos da vazão volumetrica e da pressão transmembrana no fluxo de permeado
Pre-treatments of whey to improve the permeate flux in ultra filtration (UF) membrane processes are important for economic viability of whey protein concentrate (WPC) production. Moreover, pre-treatments can also be used to improve functional properties of whey proteins. Nevertheless, membrane fouling is the main technological problem concerned to dairy indu
