In Brazil, the municipalities with sewerage system is 52,2% of the total (PNSB, 2000). Therefore, it is low figure and there are regional discrepancies, as the percentage of attendance at the southern and southeastern regions are higher then at the northern northeastern and middle western. The situation is even worse at the rural area, where most localities

14. Digital approach for the design of statistical analog data acquisition on SoCs / Uma abordagem digital para o projeto de aquisição estatística de dados analógicos em sistemas Integrados (SoCs).
With the current demand for mixed-signal SoCs, an increasing number of designers are looking for ADC architectures that can be easily implemented over digital substrates. Since ADC performance is strongly dependent upon physical and electrical features, it gets more difficult for them to benefit from more recent technologies, where these features are more va

15. Calibração de examinadores para exame epidemiologico da carie dentaria : uma avaliação mediante diferentes limiares de diagnostico / Calibration of examiners for the epidemiological examination of dental caries, an evaluation under different diagnostic thresholds
This thesis, comprising 4 studies, aimed al evaluating the examiners calibration for the dental caries epidemiological survey, under different diagnostic thresholds. Methodology of the 4 studies: Eleven examiners, having experience in epidemiological surveys, were trained for the dental caries calibration. The inclusion criteria were based on those recommend

16. Locomotion of Stramonita haemastoma (Linnaeus) (Gastropoda, Muricidae) on a mixed shore of rocks and sand
Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767) snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 days. In

17. Evaluation of methods used to estimate inhaled dose of carbon monoxide.
We have compared estimation of alveolar carbon monoxide measured either as end-expired or mixed-expired carbon monoxide tension with two spectrophotometric estimations of venous blood carboxyhaemoglobin (COHb). Estimation of mixed-expired carbon monoxide proved more convenient for patients than the end-expired method, and this estimation of carbon monoxide e

18. Lead levels on traffic-less islands.
Surveys were conducted on three traffic-less islands: Tory and Aran, off the coast of Ireland, and Sark, one of the Channel Islands off the coast of France. Identical methods were used in surveys in three other areas, all of which have heavy gasoline driven traffic. These were Jersey, another of the Channel Islands, Ebbw Vale--a mixed industrial area, and Ca

19. Pneumoconiosis in Makers of Artificial Grinding Wheels, Including a Case of Caplan's Syndrome*
Mass miniature radiography surveys in a factory producing artificial grinding wheels detected cases of pneumoconiosis, mostly of the silicotic type. All cases were traced to the department where the so-called “bond” is prepared and mixed with the abrasive grains of carborundum and artificial corundum. This ceramic-vitrified bond, similar in composition t

20. Line Probe Assay for Detection of Human Immunodeficiency Virus Type 1 Mutations Conferring Resistance to Nucleoside Inhibitors of Reverse Transcriptase: Comparison with Sequence Analysis
We compared the line probe assay (LiPA) to sequence analysis for the detection of mutations conferring resistance to nucleoside inhibitors of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT). Plasma samples from 40 patients who had received zidovudine, dideoxyinosine, and dideoxycytosine, alone or in combination, and who were enrolled i

21. Immunochemical assessment of mycotoxins in 1989 grain foods: evidence for deoxynivalenol (vomitoxin) contamination.
To assess the potential for mycotoxin contamination of the human food supply following the 1988 U.S. drought, 92 grain food samples were purchased from retail outlets in the summer of 1989 and surveyed for aflatoxin B1, zearalenone, and deoxynivalenol (DON [vomitoxin]) by monoclonal antibody-based competitive enzyme-linked immunosorbent assay (ELISA). Only o

22. Retrospective cohort mortality study of workers at an aircraft maintenance facility. II. Exposures and their assessment.
Methods are presented that were used for assessing exposures in a cohort mortality study of 15,000 employees who held 150,000 jobs at an Air Force base from 1939 to 1982. Standardisation of the word order and spelling of the job titles identified 43,000 unique job title organisation combinations. Walkthrough surveys were conducted, long term employees were i

23. Dust exposure, respiratory symptoms, and longitudinal decline of lung function in young coal miners.
OBJECTIVES: To study the role of dust exposure on incidence of respiratory symptoms and decline of lung function in young coal miners. METHODS: The loss of lung function (forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow (MEF), carbon monoxide transfer factor (TLCO)) with time and the incidence of respiratory

24. Lyme Disease Borrelia spp. in Ticks and Rodents from Northwestern China
In May 1999, field surveys of Lyme disease spirochetes were conducted around the Tianshan Mountains in Xinjiang Uygur Autonomous Region in northwestern People's Republic of China. Ixodes persulcatus ticks were obtained in a Tianchi Lake valley with primary forest, while the tick fauna was poor in the semidesert or at higher altitudes in this region. Species
