A case report of a patient who presents as chief complaint presence of stained restorations in the anterior teeth. After analysis and discussion of the clinical therapeutic approaches to be adopted, it was observed the presence of type class IV restorations on teeth 11 and 21, due to an oblique coronal fracture in the past. But the patient was not satisfied with the aesthetic result, then where was planned the realization of the removal of the restorations, for subsequently be used direct restorative materials for the correction of form, function and esthetics. The final result showed that the restorations were able to return the form, function and aesthetic dental, thereby evidencing the proven development of restorative dentistry in the solution of aesthetic problems.

The aim of this study was to determine the antioxidant activity of Moringa (Moringa oleifera Lam.) leaves flour in beef burger during storage for 120 days. Six hamburger formulations were processed: one control (without the use of additives), four with addition of Moringa leaves flour (0.10, 0.15, 0.20, and 0.25 g/100 g aggregate), and one with addition of synthetic antioxidant Propyl Gallate (0.01 g/100 g aggregate). The products were analyzed for their chemical composition with determinations of moisture, protein, dietary fiber, lipids, ash, carbohydrate, and caloric value after preparation. Microbiological and acceptance testing were performed at the beginning and after 120 days of storage. Determination of pH, instrumental color and lipid oxidation (TBARS) were performed at 1, 30, 60, 90 and 120 days of storage. All samples showed physical-chemical and microbiological tests in accordance with the Brazilian legislation. pH measurements were between 5.48 and 5.90; however, the intensity of red has changed according to the treatments and storage periods. The addition of Moringa leaves flour had no antioxidant effect on burgers, but its inclusion not only contributed to the improvement of nutritional quality, but also did not harm product acceptance.

Este trabalho teve como objetivo estudar o tratamento da manipueira pelo processo de flotação, visando estabelecer os melhores parâmetros operacionais a serem adotados, sem o uso de agentes químicos. Foram realizados os tratamentos em dois tipos de processo de flotação: por ar dissolvido e ar induzido, sendo as colunas desenvolvidas em acrílico e PVC para operação contínua em uma planta piloto. Os dois sistemas de flotação não demonstraram diferenças em relação à recuperção de proteínas, amidos e matéria graxa, porém, o processo de flotação por ar dissolvido torna a manipueira diluída devido ao volume de água utilizada, o que acaba gerando um volume de resíduo ainda maior e aumentando o custo do processo. Utilizando o processo por ar induzido, foram realizados ensaios variando vazão e temperatura, sendo os melhores resultados obtidos nas seguintes condições: vazão na faixa entre 120 e 420 mL/min e temperatura na faixa de 33 a 36 °C. Foi observada uma redução nos percentuais de remoção de matéria graxa e proteínas de 44,4% e 32,8%, respectivamente.

The biomass resulting from processing sugarcane bagasse has been considered a source of cellulose with the potential production of bio-fuels. This lignocellulose can be processed into ethanol since is hydrolyzed by chemical processes (acids) or biotechnology (enzymes) which generate sugars suit for fermentation. This study had the objective to utilize physical and chemical pre-treatment processes for prehydrolysis of sugarcane bagasse. The experimental treatment was adjusted at a factor of 4 X 2, by the combination of pre-hydrolysis timing (15, 30, 45 and 60 minutes) and sulfuric acid concentrations (7.0% and 9.0%) which was incubated at a temperature of 121° C in an autoclave. The treatment data was subjected to analysis of the variance and averages which were compared using the Tukey test with a probability of 5%. The results obtained showed that through pretreatment acid applied on the lignocellulose material, there was a significant break from the substrate fibers like cellulose, hemicellulose and lignin.
