2. Post-treatment of landfill leachate using rice husk ash as adsorbent medium
Resumo O aterro sanitário é o método mais geral de disposição de resíduos sólidos urbanos. Porém, no processo de degradação da matéria orgânica é produzido um líquido de coloração escura de alto potencial poluente sendo necessário tratamento adequado antes de seu lançamento nos corpos de água. Diversas tecnologias podem ser utilizadas no t

3. Physico-chemical characterization of centrifuged sludge from the Tamanduá water treatment plant (Foz do Iguaçu, PR)
ABSTRACT The water treatment process generates a residue called water treatment plant (WTP) sludge, which needs to be correctly characterized to ensure appropriate disposal or reuse. This study aimed to characterize the centrifuged sludge produced at the Tamanduá WTP, Iguaçu Falls City, Brazil, and considered opportunities for its reuse in the production o

4. Incidence of hydrocolloid type on quality parameters in mango leathers (Mangifera indica L.) Yulima variety
Abstract The effect of four hydrocolloids on the physico-chemical, bioactive and rheological properties in sweetened mango leather sheets of the Yulima variety were analyzed. Parametric and non-parametric statistical tests were done to analyze the differences among samples (four of treatment against two of control). The findings show significant positive ef

5. Membranas Compuestas: propiedades superficiales y estabilidad térmica
ABSTRACT The composite membranes were manufactured with crosslinking poly(vinyl alcohol) on polyethersulfone porous membranes by coating process. PES membranes were exposed to air plasma for the purpose of surface modification. The coating of the support membrane was carried out by using a polymer matrix with a crosslinking agent. The physico-chemical proper

6. Lithium containing MgAl mixed oxides obtained from sol-gel hydrotalcite for transesterification
Abstract The innumerous advantages of heterogeneous catalysts employed in biodiesel production have stimulated the search for a solid catalyst capable of replacing the industrially used homogeneous catalysts. This paper investigates the effect of the sol-gel method in the catalytic activity and stability of Li-MgAl mixed oxides prepared by the “in situ”

7. Evaluating the Potential of Biodiesel Production through Microalgae Farming in Photobioreactor and High Rate Ponds from Wastewater Treatment
In the last decade, the research works on microbial as a potential source of lipid for biodiesel production have been growing. In this work, the potential of a sludge from high-rate lagoons in urban sewage treatment, composed mainly by Chlorella sp., as oil source for biodiesel production, was studied. The potential of Chlorella sp. growth in photobioreactor

8. Strategy for Treating a Landfill Leachate by Integration of Physico-Chemical and Photo-Fenton Processes
This study reports a protocol for the treatment of a sanitary landfill leachate through integration between a stage of coagulation-flocculation, a step of filtration of the resulting suspension, and application of the photo-Fenton process using a ferrioxalate complex and solar irradiation. The best results for turbidity removal by coagulation-flocculation we

9. Validation of a Chromatographic Analytical Method for Quantification of Benznidazole Incorporated in Nanostructured Lipid Formulations
Benznidazole (BNZ) has been employed in the treatment of Chagas disease; however, its low water solubility is a drawback, which can be overcome by incorporating BZN within nanostructured systems. The aim of this work was to validate a chromatographic method for determination of BZN incorporated in nanoemulsions (NE) and nanostructured lipid carriers (NLC). T

12. Influence of heat treatment on the sensory and physical characteristics and carbohydrate fractions of french-fried potatoes (Solanum tuberosum L.)
AbstractThe aim of this study was to analyze the impact that heat treatment with salts and freezing processes on the sensory, instrumental, and physico-chemical characteristics of fried potatoes of the Monalisa cultivar. The potatoes were blanched in distilled water (P); sodium chloride solution (B1); calcium chloride solution (B2), and a solution with both
