1. Caracterização microbiana e remoção do alquilbenzeno linear sulfonado em reator EGSB / Microbial characterization and removal of linear alkylbenzene sulfonate in EGSB reactor
O presente trabalho teve por objetivo avaliar a eficiência de remoção do surfactante aniônico alquilbenzeno linear sulfonado (LAS) em reator anaeróbio de leito granular expandido - EGSB (1,5 litros) com recirculação e alimentação com meio mineral. Além de caracterizar filogeneticamente a diversidade de bactérias na presença do surfactante. O sist

2. In vitro evaluation of the Nd:YAG and Er:YAG lasers irradiation on the root sealing with different root canal filling cement / Avaliação In vitro da irradiação com laser de Nd:YAG e Er:YAG no selamento radicular, variando-se o cimento obturador do sistemas de canais radiculares
The aim of this in vitro study was to analyze two high power lasers irradiation effects before the root canal filling procedure with resin endodontic cements on the lateral sealing. Thirty-six permanent human molars were endodontically treated and randomly assigned in nine experimental groups (n=4) according with the subsequent dentin treatment. The groups w

3. Uso de águas residuárias tratadas na cultura de hortaliças: avaliação de enteroparasitas e metais pesados / The use of treated residuary water to grow vegetables: assessment of enteroparasites and heavy metals.
Water shortage is a worldwide problem, and the use of residuary water is an important theme regarding the preservation of water bodies and conscious use of the resources available. This study aimed to evaluate the viability of using treated residuary water from the Biological Wastewater Treatment Plant of Ribeirão Preto (ETE-RP) to grow vegetables, through

5. In vitro evaluation of the precision of working casts for implant-supported restoration with multiple abutments
OBJECTIVE: The purpose of this study was to compare the accuracy of two working cast fabrication techniques using strain-gauge analysis. METHODS: Two working cast fabrication methods were evaluated. Based on a master model, 20 working casts were fabricated by means of an indirect impression technique using polyether after splinting the square transfer coping

6. Água e saúde dos povos indígenas Yanomami (Região do Toototobi, Balawaú, Demini e Paapiú) e Wapishana (Maloca da Malacacheta) - Brasil
The present work is a result of the interest in studying the quality of water consumed by Yanomami and Wapishana Indians, as well as its influence on these people health. It was carried through a search among health professionals who care for Indian patients aiming to get socio environmental data and list the principal diseases associated with quality of wat

7. Evaluation of the Autoanalysis Colilert test for detection and enumeration of total coliforms.
The Autoanalysis Colilert (AC) test was compared with the membrane filter (MF), 10-tube multiple-tube fermentation (MTF) technique, and the presence-absence test as described in Standard Methods for the Examination of Water and Wastewater for the detection and enumeration of total coliforms in water. The methods were evaluated with 31 samples from seven diff

8. Comparison of EC broth and medium A-1 for the recovery of Escherichia coli from frozen shucked snow crab.
Two variations of the multiple-tube fermentation technique were used to enumerate fecal coliforms in commercially processed, frozen crab meat. These were the EC confirmation test and a more rapid method that requires medium A-1. The method with medium A-1 was more specific than the EC confirmation test for detecting Escherichia coli type 1. E. coli was isola

9. COMPARISON OF THE DEVELOPMENTAL CYCLES OF SOME MEMBERS OF THE GENUS NOCARDIA1
Adams, James N. (University of Georgia, Athens) and Norvel M. McClung. Comparison of the developmental cycles of some members of the genus Nocardia. J. Bacteriol. 84:206–216. 1962.—A staining technique specific for cell walls was used to determine the characteristic development of Nocardia rubra, N. erythropolis, N. asteroides, and N. canicruria comb. no

10. Evaluation of commercial presence-absence test kits for detection of total coliforms, Escherichia coli, and other indicator bacteria.
Evaluations of several commercial presence-absence (P-A) test kits were performed over a 6-month period in 1990 by using the Ontario Ministry of the Environment (MOE) P-A test for comparison. The general principles of the multiple-tube fermentation technique formed the basis for conducting the product evaluations. Each week, a surface water sample was dilute

11. Human beta-defensin-1: an antimicrobial peptide of urogenital tissues.
Antimicrobial peptides are widely distributed mediators of innate host defense in animals and plants. A 36 amino acid antimicrobial peptide belonging to the defensin family, and named human beta-defensin-1 (HBD-1), was purified recently from hemodialysate fluid, but its tissue sources were not identified. By Northern blotting, we found the highest concentrat
