Four screens for the rapid (4 to 6 h) biochemical detection of pathogens from enteric isolation media are described. The Salmonella screen consisted of Kligler iron agar (KIA), motility-indole-urea-tryptophan-deamination semisolid medium (MIU-TDA), and the o-nitrophenyl-beta-D-galactopyranoside (ONPG) test; the Shigella screen consisted of KIA, MIU-TDA, the ONPG test, and the lysine decarboxyla...

velocity analysis is one of the most important step in seismic data processing. it affects not only many processing steps directly and indirectly, but also is known as a primary interpretation of the data. however, it can also be assumed as one of the most time consuming processing step. the conventional velocity analysis method measures the energy amplitude along hyperbolic trajectories within...

The objective of this study was to improve the overall performance a glassy carbon electrode (GCE) for detection 2,6-diaminotoluene (TDA), possibly carcinogenic primary aromatic amines (PAAs) that poses serious risk consumer’ health because they can transfer from multilayer food packages including adhesives based on polyurethane (PU) systems, food. modification surface made by means multi-walle...
