Introduction: Many vegetables are eaten raw which can lead to the prevalence of food borne diseases if not properly sanitized. The aim of this study was to compare the effect of chlorine, bleach and multioxidant solution in disinfection of edible vegetables. Materials and Methods: In this experimental study, 100 g of vegetables (lettuce, basil and mint) was disinfected by sodium hypochlorite, ...

In developing wastewater treatment regulations and guidelines for potable reuse, the reduction of pathogens is critical importance. draft regulations, state California has proposed overall process log values (LRVs) 20, 14, 15 respectively viruses, Giardia cysts, Cryptosporidium oocysts, direct reuse. meeting requirements, agencies have sought to obtain credit LRVs achieved consistently through ...

We prove that the modular communication complexity of the undi-rected graph connectivity problem UCONN equals (n), in contrast to the well{ known (n log n) bound in the deterministic case, and to the (n log log n) lower bound in the nondeterministic case, recently proved by Raz and Spieker. We obtain our result by combining MM obius function techniques due to Lovasz and Saxe with rank and proje...

We consider the problem of generating hard instances for the Satisfying Assignment Search Problem (in short, SAT). It is not known whether SAT is di cult on average, while it has been believed that the Factorization Problem (in short, FACT) is hard on average. Thus, one can expect to generate hard-on-average instances by using a reduction from FACT to SAT. Although the asymptotically best reduc...
