1. Soil Chemistry after Irrigation with Treated Wastewater in Semiarid Climate
ABSTRACT Soil irrigation using treated wastewater in the Brazilian semiarid region is a promising practice as this area currently faces water scarcity and pollution of water resources by domestic sewage. The aim of this study was to evaluate the use of treated wastewater in drip irrigation and its effect on the chemistry of soil cultivated with squash (Cucur

2. Evaluation of the measurement system of individual water popular in buildings located in the city of Salvador, Bahia. / Avaliação do sistema de medição individualizada de água em prédios populares situados na cidade do Salvador-Bahia
The aim of this work is to evaluate the results achieved with the introduction of an individual water consumption metering system, as opposed to an old collective metering system, installed in low cost residential buildings supplied by the EMBASA - the State water supplier.The study was carried out in 15 buildings located in Salvador, Bahia. The research cov

3. Estimativa da infiltração e do afluxo devidos à precipitação na rede de esgoto sanitário em município de pequeno porte.
The main purpose of this work was to identify and to estimate the rainfall derived infiltration and inflow (IADP) into the sewer in a small city and to do an analysis of their influence on this collection system. This work was composed by field measurements on the sewage flowrate output and volume arriving to the Sewage Pumping Plant Station, simultaneously

4. Evaluation of organic load measurement techniques in a sewage and waste stabilisation pond
A Demanda Bioquímica de Oxigênio (DBO) e a Demanda Química de Oxigênio (DQO) são os principais indicadores rotineiramente utilizados para avaliação de carga orgânica em matrizes de interesse ambiental. Nesse contexto, avaliações da possibilidade de substituição das testes de DBO e DQO por medidas de Carbono Orgânico Dissolvido (COD) são apresen

5. Muramic Acid Measurements for Bacterial Investigations in Marine Environments by High-Pressure Liquid Chromatography
Muramic acid, a constituent of procaryotic cell walls, was assayed by high-pressure liquid chromatography in samples from several marine environments (water column, surface microlayer, and sediment) and a bacterial culture. It is used as a microbial biomass indicator. The method gave a good separation of muramic acid from interfering compounds with satisfact

6. In situ measurement of methane oxidation in groundwater by using natural-gradient tracer tests.
Methane oxidation was measured in an unconfined sand and gravel aquifer (Cape Cod, Mass.) by using in situ natural-gradient tracer tests at both a pristine, oxygenated site and an anoxic, sewage-contaminated site. The tracer sites were equipped with multilevel sampling devices to create target grids of sampling points; the injectate was prepared with groundw

7. Measurement of the effects of cadmium stress on protozoan grazing of bacteria (bacterivory) in activated sludge by fluorescence microscopy.
The effect of cadmium stress on protozoan bacterivory in sewage sludge was measured by experimentally exposing sludge communities to 0 to 150 mg of Cd per liter for up to 6 h and then determining the rates of protozoan grazing on bacteria, using a double-staining technique and epifluorescence microscopy. Bacterivory was measured by incubating the sludge with
