1. IDENTIFICAÇÃO DE UM SISTEMA DE LODO ATIVADO DE PEQUENA ESCALA DESENVOLVIDO EM LABORATÓRIO / IDENTIFICATION OF A ACTIVATED SLUDGE SYSTEM ON SCALE SMALL DEVELOPED IN THE LABORATORY
In activated sludge systems, the dissolved oxygen is used by microorganisms to decompose organic matter and treatment of wastewater. In these systems the dynamics of dissolved oxygen has been seen as the main source of information to obtain online information about the treatment process. Thus, the development of an appropriate model for the dynamics of disso

2. ESTIMAÇÃO DA TAXA DE CONSUMO DE OXIGÊNIO EM SISTEMAS DE LODO ATIVADO USANDO FILTRO DE KALMAN E CONTROLE PWM DA CONCENTRAÇÃO DE OXIGÊNIO DISSOLVIDO / ESTIMATION OF THE RATE OF OXYGEN CONSUMPTION IN ACTIVATED SLUDGE SYSTEMS USING KALMAN FILTER AND PWM CONTROL OF THE CONCENTRATION OF DISSOLVED OXYGEN
A medição e a utilização da taxa de consumo de oxigênio (TCO), ou taxa de respiração, é muito importante para os processos biológicos de tratamento de águas residuais. A TCO fornece informações a respeito da atividade biológica e pode indicar a presença de elementos tóxicos capazes de comprometer a unidade de tratamento. Devido à carência de

5. EFEITOS DO ASSOREAMENTO SOBRE AS COMUNIDADES DE PEIXES DE IGARAPÉS DA BACIA DO RIO URUCU, COARI, AMAZONAS, BRASIL.
The siltation and the soil use effects on the fish assemblages were evaluated in Província Petrolífera de Urucu streams, between the months of September and December of 2004. The fish were collected in open water and in litter benches located in meanders. Fishnests, dipnets (rapiché) and traps were utilized to sample 27 streams with a total of 108 collect

6. Avaliação da produção de odor na estação de tratamento de esgoto Paranoá e seus problemas associados
The Federal District of Brazil has been suffering problems of emanations of odors proceeding from sewage treatment plants (STP). For this reason, this work has the objective of evaluating the production of odor in the Paranoá sewage treatment plant (Paranoá STP), in Federal District, and its associated problems, employing hydrogen sulfide (H2S) as an indic

7. Oxido misto de SiO2/SnO2,SiO2/SnO2/Fosfato : propriedades e aplicações / The SiO2/SnO2, SiO2/SnO2/fosfato mixed oxide : properties and applications
The present work describes the preparation of SiO2/SnO2 mixed oxide obtained by the sol-gel processing method with Sn compositions (in wt %) of 4, 13 and 18%. The high specific surface and the presence of Lewis and Brfnsted acid sites, constitutes an interesting substrate for preparing new classes of chemically modified electrodes. In a specific application,
