In this paper, an artificial pollution test is carried out to study the leakage current of porcelain insulators. Fractal theory is adopted to extract the characteristics hidden in leakage current waveforms. Fractal dimensions of the leakage current for the security, forecast and danger zones are analyzed under four types of degrees of contamination. The mean value and the standard deviation of ...

UNLABELLED BACKGROUND The objective of this study was to examine the potential environmental risk of tailings resulted after precious and base metal ores processing, stored in seven impoundments located in the Aries river basin, Romania. The tailings were characterized by mineralogical and elemental composition, contamination indices, acid rock drainage generation potential and water leachab...

The origin of meat products and any porcine contamination should be carefully analyzed for Halal certificaiton. Different methods are utilized for origin detection and of meat and meat products. Due to the sencitivity and selectivity, Real Time PCR is used widely in the area. In this method, even very small amounts of DNA can be determined. In this study, sausages from the most famous sausage b...

The European Commission and the Food and Drug Administration in the USA suggest that risk management and assessment methods should be used to identify and control sources of microbial contamination1,2. A risk management method has been described by Whyte3,4 that is based on the Hazard Analysis and Critical Control Point (HACCP) system but reinterpreted for use in cleanrooms, and called Risk Man...

The requirements for minimising microbial contamination in pharmaceutical cleanrooms are in regulatory documents published by authorities that include the European Commission1 and the Food and Drug Administration in the USA2. These authorities also suggest the use of risk management and assessment techniques to identify and control sources of microbial contamination3,4. The authors of this arti...
