2. Evaluation of the quality of the water consumed by the population of the District of Sana - Macaé - RJ. / Avaliação da qualidade da água consumida pela população do distrito do Sana Macaé - RJ.
The water is vehicle of pathogenic microoganisms and noxious substances for human health, so its great importance the control of the physiochemical and microbiological characteristics. The aim of this study was to evaluate the quality of the water consumed by the population of the District of Sana - Macaé - RJ, through physiochemical, bacteriological and pa

3. SÍNTESE, ESTRUTURA E AVALIAÇÃO DA ATIVIDADE ANTIMICROBIANA DE COMPLEXOS METÁLICOS COM SULFAMETOXAZOL / SYNTHESIS, STRUCTURE AND ANTIMICROBIAL ACTIVITY EVALUATION OF METALLIC COMPLEXES WITH SULFAMETHOXAZOLE
This work presents the study of compounds obtained from interaction of sulfamethoxazole with copper, cadmium, mercury and nickel acetates, gold triphenilphosphine acetate / chloride and with silver chloride. The synthesis and the characterization of the new compounds were accomplished by the analyses of the reactivity, the coordinative behavior and to the co

4. Evaluation of filtration ditches as method of post treatment of effluent anaerobic : removal natural of pathogens and nutrients in application of high hydrauli rates / Avaliação das valas de filtração como metodo de pos-tratamento de efluente anaerobico : remoção natural de patogenos e nutrientes na aplicação de altas taxas hidraulicas
The aim of this work was to study filtration ditches as a method of low cost applicable the isolated homes and the small Brazilian municipalities for the posttreatment of anaerobic effluent from a system septic tank with anaerobic unit in the removal of natural nutrients and pathogenic microorganisms. For the research were analyzed three filtration ditches o

5. Evaluation of some physico-chemical properties biologicals of the propolis produced in Peru. / Avaliação de algumas propriedades fisico-quimicas e biologicas das propolis produzidas no Peru.
The aim of this work was to analyse the physyco-chemical properties, as well as, identify and quantify the phenolic compounds presented on the propolis collected by Apis mellifera in Perú. The ethanolic extract of propolis presented a variety from coloration of primrose to dark brown, with soluble substances that range between 56,21% to 67,35%. Using Ultrav

6. Stimulation of L-asparate beta-decarboxylase formation by L-glutamate in Pseudomonas dacunhae and Improved production of L-alanine.
The formation of L-asparate beta-decarboxylase by Pseudomonas dacunhae was compared on media containing a variety of organic acids and amino acids as a carbon source. Although the enzyme was formed constitutively when the organism was grown on basal medium or on that containing tricarboxylic acid cycle intermediates, it was induced twofold by L-glutamate and

7. New pharmacokinetic in vitro model for studies of antibiotic activity against intracellular microorganisms.
The capacity for intracellular growth is an important survival strategy for a large group of common pathogens. Helicobacter pylori, the etiological agent for gastritis and duodenal ulcer, has been shown by both in vivo and in vitro studies to have the capacity to invade epithelial cells. In vitro models are used to study the effect of antibiotics on microoga
