1. Avaliação da capacidade de remoção da camada residual dentinária com o uso do Endo PTC em diferentes formulações, associado a duas concentrações de hipoclorito de sódio, utilizando ou não irrigação final com EDTA. / Evaluation of the ability to remove the smear layer of dentin with the use of Endo PTC in different formulations, combined with two concentrations of sodium hypoclorite, with or without final irrigation with EDTA.
The action of the instruments on the walls of the root canal provides the smear layer development, which is an extract of organic and inorganic matter, with amorphous appearance, irregular and granular surface which is set down on the dentin surface in the measure that its formation occurs, and when it is not removed, can interfere on the desired sealing dur

2. Remoção de compostos orgânicos causadores de gosto e odor em águas de abastecimento em sistemas pós-filtros adsorvedores de carvão ativado granular. / Removal of taste and odor producing organic substances in water supply in post-filter granular activated carbon adsorber systems.
The main purpose of this research was to study the performance of granular activated carbon post filter adsorbers made of bituminous coal and vegetal coal (coconut), regarding, mainly, removal of 2-methylisoborneol and trans-1,10-dimethyltrans- 9-decalol. The experimental researches were conducted in the water treatment plant Alto da Boa Vista, using four pi

3. Polímeros extracelulares insolúveis (EPS) nos reatores anaeróbios operados em bateladas seqüenciais: caracterização e fatores que favorecem a produção / Insoluble exopolysaccharides (EPS) in the anaerobic sequential batch biofilm reactor: characterization and factors that enhance the production
The insoluble exopolysaccharides (EPS) produced in anaerobic treatment processes from some kinds of wastewater are unwelcome due to operational problems that it may cause, making the process unfeasible most of times. The anaerobic sequential batch biofilm reactor (ASBBR), containing immobilized biomass, is a new configuration of reactor that has been studied

4. Síntese e caracterização de substâncias semelhantes aos ácidos húmicos de carvão de eucalipto, e sua interação com diclorofenol, cálcio, manganês e alumínio / Synthesis and characterization of humic acid-like substances from eucalypt charcoal, and its interaction with diclorofenol, calcium, manganese and aluminium
A wide range of commercial products containing humic substances have been applied successfully in agricultural and environmental remediation systems. Regarding their beneficial remediation characteristics, there is a high potential to adsorb heavy metals and organic pollutants, thus reducing their bioavailability. Industrially, they are extracted from non-re

5. Evaluation of the departure of stream beds cultivated in the residuary water treatment of the banana candy processing. / Avaliação da partida de leitos cultivados no tratamento de agua residuaria do processamento de doce de banana.
The purpose of this research was to test the performance of a constructed macrophytes wetland in the reduction of organic material and solids clearance of wastewater characteristic of the banana candy processing. There are few reports about the use of constructed wetlands in the treatment of wastewater from food processing and none of them refers to its kind

6. Corantes têxteis
A dye is a colored substance used to impart permanent color to other substances. Its most important use is in coloring textile fibers and fabrics. The removal of colour from dyehouse waste waters is currently a major problem in the textile sector. This paper provides an overview of the treatment technologies that can currently be used by the textile processo
