Caracterização físico-química e microbiológica de diferentes amostras de uma precipitação coletada e armazenada após passagem por telhado

The decreasing availability of drinking water is a problem that has existed for a long time and continues to be aggravated, especially by the increase in population and pollution of water resources. Due to the need to find alternatives in order to ensure water supplies in sufficient quantity and quality for consumption by populations, rainwater collection arises as an alternative. The present study was developed in Ipeúna-SP, consisting of an experimental system of collection and storage of rainwater on the roofs of buildings. Samples of the same precipitation, differentiated through the initial disposal and treatment of the collected water, were stored during a period of six months and monitored through physical, chemical and microbiological analyses. With the results, the qualitative characteristics of the stored precipitation were found, the main differences among the samples were identified and the needs of treatment were studied.

Histórico e aspectos tecnológicos do processamento da linguiça cuiabana

This paper reports the data on the cuiabana sausage historical aspect, and from the study performed on its technical/sensory characteristics. Four formulations of cuiabana-type sausage were prepared, varying the basic raw material (bovine, chicken and swine meats). For processing these sausages, the raw meats (beef, chicken and pork) were cut into cubes and together with the other ingredients (garlic, cheese, pepper and chives) they were weighed and homogenized. The resulting mixture was refrigerated for 24 hours for intensifying the flavor. Thereafter, it was stuffed into natural casings. These prepared samples were characterized on the physical-chemical profile and on the shelf life under refrigeration for over a seven day-storage in order to assess the microbiological contamination (total coliforms and fecal thermotolerant bacteria), sulphite-reducing clostridium, Salmonella spp., coagulase-positive Staphylococcus), and pH. The sensory evaluation and statistics analysis were carried out on the different types of laboratory- processed cuiabana sausage. Introducing over time changes in the cuiabana sausages formulation are positive factors; therefore, variations in the formulations it is feasible to get a better final product than that original one, and it might be resulted from the market demand.

Production and Characterization of Composite Material Useful as a Protective Barrier in Electronic Applications

This work describes the production and characterization of a selective membrane useful for electronic devices. The membrane was a composite made by a thin film of plasma-polymerized HFE (methyl nonafluoro(iso)butyl ether) immersed in plasma-polymerized HMDS (hexamethyldisilazane) film, a third phase being 5 µm starch particles included in this matrix. The film was deposited on silicon substrates and its physical, chemical and adsorption characteristics were determined. Infrared and x-ray photoelectron spectroscopy analyses showed fluorine and carboxyl groups on the bulk and the surface, respectively. SEM results indicate the film is conformal even if starch is present. Optical microscopy analysis showed good resistance toward acid and base solutions. Quartz crystal microbalance indicated adsorption of polar organic compounds on ppm range. This thin film is environment-friendly and can be used as a protective layer or in electronic devices due to adsorption of volatile organic compounds.
