1. SEWAGE PERFORMANCE OF A NEW TYPE OF FLAP FILTER
ABSTRACT The drainage performance of a mesh filter determines the water consumption degree of the filter and the efficiency of the next work cycle. Through analysis, we found that the influent flow rate and the sediment content of the influent were important influencing factors. This experiment focused on the drainage time, pressure difference, and cleanline

2. Obtaining and characterization of anthocyanins from Euterpe oleracea (açaí) dry extract for nutraceutical and food preparations
Abstract The main constituents of the Euterpe oleracea Mart., Arecaceae, fruits (açaí) are anthocyanins. This paper aimed to standardize the extraction process and characterize an anthocyanin-rich dry extract obtained from this fruit. A 23 full factorial design was used. The volumes of ethanol 92% and acetic acid and the extraction time were used as factor

7. Análise comparativa dos fatores influentes na tensão última de protensão em cabos aderentes e não aderentes / Comparative analysis on the influent factors in the ultimate stress in bonded and unbonded tendons
A protensão não-aderente caracteriza-se pela liberdade de deslocamento relativo entre o cabo de protensão e a fibra de concreto adjacente. A tensão na armadura de protensão no estado limite último é de difícil obtenção, não sendo dependente apenas das deformações em uma determinada seção transversal, mas sendo função de todas as deformaçõe

8. Assessment of the dye removal capability of submersed aquatic plants in a laboratory-scale wetland system using anova
The textile dye (Basic Blue 41(BB41)) removal capability of a laboratory-scale wetland system was presented in this study. Twenty glass aquaria were used to establish the wetland. Myriophyllum spicatum and Ceratophyllum demersum were planted in the aquaria and acclimated. After establishing flow conditions, the aquaria were fed with synthetic wastewaters con

10. VariaÃÃo sazonal da atividade da rubisco e das enzimas de sÃntese e hidrÃlise da sacarose em plantas de seringueira [Hevea brasiliensis (Willd ex. Adr de Juss.) Muell.-Arg], em Lavras/MG / Seasonal variation of Rubisco and sucrose synthesis and hydrolisys enzymes activities in rubber trees [Hevea brasiliensis (Willd ex. Adr. de Juss.) Muell.-Arg], in Lavras, MG.
The growth of rubber tree cultivation in Brazil has happened because of growing of natural rubber market. With aim to escape of âSouth American leaf blightâ â a common disease in amazonian region â the rubber tree expansion has privileged no traditional regions in Brazil. In Minas Gerais, where rubber tree cultivation is still incipient, new researches a
