Água de consumo humano como fator de risco à saúde em propriedades rurais Drinking water in rural farms as a risk factor to human health

Abstract: Objective To assess the sanitary quality of drinking water in rural farms through counts of microbiological indicators. Methods A total of 180 drinking water samples from sources, reservoirs and water from site of consumption were collected in 30 rural farms located in the northeast region of the sate of Sao Paulo. The most probable number of total coliforms, Escherichia coli and mesophilic microorganisms were determined. Also, the presence of protection measures for water supplies wase verified. Results The study results showed that 90.0% of drinking water samples from sources, 90.0%

Strong infrared spectral broadening in low-loss As-S chalcogenide suspended core microstructured optical fibers

Abstract: We report the fabrication and characterization of the first guiding chalcogenide As2S3 microstructured optical fibers (MOFs) with a suspended core. At 1.55 µm, the measured losses are approximately 0.7 dB/m or 0.35 dB/m according to the MOF core size. The fibers have been designed to present a zero dispersion wavelength (ZDW) around 2 µm. By pumping the fibers at 1.55 µm, strong spectral broadenings are obtained in both 1.8 and 45-m-long fibers by using a picosecond fiber laser.

Effects of six carbohydrate sources on dog diet digestibility and post‐prandial glucose and insulin response*

Abstract: The effects of six extruded diets with different starch sources (cassava flour, brewer's rice, corn, sorghum, peas or lentils) on dog total tract apparent digestibility and glycemic and insulinemic response were investigated. The experiment was carried out on thirty-six dogs with six dogs per diet in a completely randomized design. The diets containing brewer's rice and cassava flour presented the greatest digestibility of dry matter, organic matter and gross energy (p or = 30 min) were greater for sorghum, lentil and pea diets (p < 0.05). Variations in diet digestibility and post-prandial response can be explained by differences in chemical composition of each starch source including fibre content and starch granule structure. The nutritional particularities of each starch ingredient can be explored through diet formulations designed to modulate glycemic response. However, more studies are required to support these.
