the objective of the current study was to evaluate the reproducibility of a reverse transcriptase pcr (rt-pcr)-based technique to differentiate viable and dead salmonella cells in raw and sterilized milk. the microorganism was initially inoculated into the milk samples followed by incubating at 37°c for 4 h prior to inactivation by heat at 80°c for 10 min. the treated and non-treated samples we...

the environmental rules of reverse logistic networks have caused important economic growth in the past decades. to integrate forward logistic networks with reverse logistics networks a helpful method is to design both networks simultaneously. considering more retrieval choices in modeling reverse logistic systems can be very critical. this article contains a mixed integer linear programming mod...

In the context of Calculus Variations for non-convex, vector variational problems, natural process going from a function $$\phi $$ to its quasiconvexification $$Q\phi is quite involved, and, most time, an impossible task. We propose look at reverse process, what might be called inverse quasiconvexification: start _0$$ , and find functions which _0=Q\phi . addition establishing few general princ...

Purpose Stachybotrys atra has achieved great notoriety recently as a mould capable of producing mycotoxin, a potentially quite harmful substance. Because of news reports, patients have become quite concerned about “mould allergy” as the cause of an increasing number of symptoms. We set out to discover what percentage of patients referred to regional Allergy clinics have become sensitized to mou...
