In 1994, an outbreak of E. coli O157:H7 infection was linked to dry, fermented, pork and beef salami. In response to this first implication of a dry fermented sausage product, the United States Department of Agriculture/Food Safety Inspection Service developed guidelines requiring sausage manufacturers to validate that their processes achieve a five-log reduction of E. coli O157:H7. Various val...

this study investigated the effectiveness of heat treatment (50°c, 60°c and 70°c for 1 h and 2h at 75-80% rh) and cold treatment (0°c and-5°c for 24h and 48h) in the control of storage pests in zahedi and piyarom dates. before and after each treatment, the number of surviving adults, larvae, pupae and eggs were recorded and the percentage of infestation was calculated. the dates were treated at...

We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical antiinvariant lightlike hypersurfaces. We consider lightlike hypersurfaces with respect to a quartersymmetric nonmetric connection which is determined by the product structure. We give some equivalent conditions ...
