Kaolin is often used as an excipient in pharmaceutical and cosmetic industries well anticaking, bulking, absorbent, opacifying agent. It also required some with a limited number of microbial contaminations, but no study has explored the reduction these contaminant microbes based on requirements. Therefore, this aims to produce kaolin that complies contamination specifications. Several methods w...
For the long term successful operation of the superconducting TESLA accelerator it is essential to avoid any accidental contamination of the accelerating cavities. We discuss several failure scenarios of the beam vacuum system that could potentially result in such contaminations. The risk of individual failure situations is evaluated as well as preventive measures to avoid them.
The objective of this study was to determine the level of preservatives and microbiological loads in various brands of commercially available chili bo (paste). Fifteen different brands of chili bo obtained from the local market and hypermarkets were analyzed for pH, moisture and benzoic acid content, microbiological loads (aerobic, anaerobic, aerobic spores, and fungi), and thermophilic microor...
This work presents a demonstrator for online monitoring of pesticides or water contaminants which is robust, fast, specific and low cost. The system is designed for continuous monitoring in water matrices (sourceand surface water, treated waste water), and is thus completed with an automated fluidics. The main characteristics of the system are: (a) Detection based on competitive immunoassay; (b...
This work analyzes the impact of some kind of contaminants and wrong model assumptions on concentration graph models. The impact is measured in terms of model selection as the correct identification of the conditional independence structure of a vector of gaussian variables. Four different kinds of source of contamination were investigated, in order to consider both the case of occurrence of gr...
