1. Mycotoxin contamination of diets for beef cattle finishing in feedlot
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin usi

5. Good Manufacturing Practices, Hazard Analysis and Critical Control Point plan proposal for distilleries of cachaça
ABSTRACT: Cachaça poses many quality (appearance, taste, consumer acceptability) and safety hazards (chemical, metal, and microbiological contaminations during the process). In this work, an effort is made for the quality and safety analysis of cachaça, by describing and outlining the potential hazards in every step of the process. This study revealed that

6. MEASURING THE CONDUCTIVITY OF VERY DILUTE ELECTROLYTE SOLUTIONS, DROP BY DROP
Undergraduate experiments on ionic conductivity are common practice in general chemistry and advanced physical chemistry laboratories. Often, the conductivities are measured for solutions prepared for various salts, in a range of concentrations, and the relationship between solution conductivity and concentration is interpreted in terms of the Kohlrausch law

7. Efficiency of treatments for controlling Trichoderma spp during spawning in cultivation of lignicolous mushrooms
Trichoderma spp is the cause of the green mold disease in mushroom cultivation production. Many disinfection treatments are commonly applied to lignocellulose substrates to prevent contamination. Mushroom growers are usually worried about the contaminations that may occur after these treatments during handling or spawning. The aim of this paper is to estimat

8. Abrasive blasting contamination in Super Duplex and carbon steels - a quantification approach by rietveld analysis
A methodology for quantifying the contamination after abrasive blasting by Aluminum Oxide and Martensitic Carbon Steel particles in Super Duplex and Carbon Steel substrates has been developed. The method consisted of performing x-ray diffraction in the blasted steel substrates and calculating the particle contamination using Rietveld Quantitative Method. In

9. Sulfur sources in protein supplements for ruminants
The present study evaluates the efficiency of different sulfur sources for ruminant nutrition. The fiber digestibility and the amino acid profile were analyzed in the duodenal digesta of crossbred steers fed Brachiaria dictyoneurahay. The sources utilized were elemental sulfur (ES70S), elemental sulfur (ES98S); calcium sulfate in hydrated (HCS), CaSO4.2H2O,

10. Ardra profiles of bacteria and archaea in mangrove sediments with different levels of contamination in the estuarine complex of Paranaguá, Brazil
The mangrove's sediments from the coastal areas under human activities may contain significant contaminations by hydrocarbons, even when there are no visual evidences of it. The microorganisms are essential to these ecosystems, especially in the control of their chemical environment. Sediment samples were collected in two regions under different environment

12. Monitoramento temporal e espacial de contaminações bacterianas na produção de bioetanol: caracterização molecular por T-RFLP e detecção quantitativa por qPCRde comunidades formadoras de biofilmes / Temporal and spatial monitoring of bacterial contamination in bioethanol production: a molecular characterization by T-RFLP and quantitative detection by qPCR of community-formers biofilms
Bacterial contamination by Lactobacillus, Bacillus and Leuconostoc and other lactic acid bacteria is one of the main factors that affects the yield in alcoholic fermentation process. Biofilm formation protects the bacteria community and it is a permanent source of contamination. For characterization of these contaminations in (1) biofilms from centrifuge, ta
