1. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning

2. Analysis of the efficiency of flood control methods for the attenuation of peak flow using the SWMM - Storm water management model / Análise da eficiência de métodos de controle de Enchentes na atenuação de picos de cheias utilizando o modelo computacional SWMM Storm Water managemente model
This research presents an evaluation of the eficiency of four flood control measures applied to an urban basin in the city of Goiânia, State of Goiás, Brazil. Goiânia shows frequent flooding problems. The following factors have been identified as causes of the floodings: (1) significant number of impervious areas (2) lack of green areas, (3) insuficient c

3. Structural and non-structural actions for flood control Fragoso River basin at Olinda city (Brazil) / Medidas estruturais e nÃo-estruturais de controle de escoamento superficial aplicÃveis na Bacia do Rio Fragoso na cidade de Olinda
A crescente ocupaÃÃo urbana, em alguns casos de forma desordenada, sem grandes atenÃÃes ao controle do escoamento superficial existente, resultou em problemas de drenagem cada vez maiores para muitas cidades brasileiras. Na maioria dos casos, as bacias urbanas possuem Ãreas que sÃo assoladas por inundaÃÃes e alagamentos freqÃentes e que trazem todo

4. Implementation of stormwater storage facilities for low income dwelling: the CDHU experiences. / Implantação de reservatórios de detenção em conjuntos habitacionais: a experiência da CDHU.
New stormwater control techniques have emerged during last years, trying to mimic and keep the natural conditions of hydrologic cycle. One of these measures, known as storage facility, detains part of the rainfall runoff to release it at controlled rates downstream, attenuating the hydrograph peak and redistributing the volume over a certain period of time.

5. Cenários de reúso de água pluvial e controle da drenagem visando a recuperação ambiental da micro-bacia do alto Tijuco Preto, São Carlos-SP / Scenarios of rain water reuse and control of urban drainage to environmental recovering the Alto Tijuco Preto micro basin, São Carlos-SP, Brazil
The research aims to compose planning scenarios for Master Plan using measures of environmental recovering to control of urban drainage at the scale of an ungauged basin selected. Hydrologic simulations are assessed by the implementation of several measures as: a) indirect impacts of rain water use system in the urban lot, b) urban arborization, c) detention

6. Continuous Oxidative Assimilation of Acetic Acid and Endogenous Protein Synthesis Applicable to Treatment of Nitrogen-Deficient Waste Waters
A previous study indicated that the oxidative assimilation capacity of a heterogeneous microbial population for acetic acid did not return to the initial value after a period of endogenous respiration in the presence of ammonium sulfate. In view of this finding it was not possible to recommend fully the use of a continuous oxidative assimilation process for

7. Application of ribotyping for differentiating aeromonads isolated from clinical and environmental sources.
We have investigated the usefulness of ribotyping for the differentiation of aeromonads isolated from five patients with gastroenteritis and from the source water, treatment plant, and distribution system of a small public water supply. Aeromonas hydrophila and Aeromonas caviae were isolated from fecal specimens preserved in Cary-Blair transport medium by us
