Previous research has identified Campylobacter as one of the leading causes of foodborne illness. Poultry and poultry products have been identified as a major source of Campylobacter in human infections. Although many risk factors that contribute to Campylobacter levels have been identified, precise identification of the most effective sites for intervention has not been established. Epidemiolo...

Nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. It is almost used as a first and the most applicable choice in separation methods. In this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. The study was carried out by using a 3-D...

This is the first study to examine effect of three different cultivation methods (bottom-tray culture, suspended-tray and beach/bottom culture) on growth survival rates snout otter clam, Lutraria philippinarum, after 12 months grow-out from seed commercial size. Analyses included weight, survival, shell size, total fat. Although results showed limited differences in among methods, were signific...

tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. however, there are some doubts about the effect of attachment placement i...

This contribution proposes a Mixed Integer Non Linear Programming (MINLP) formulation for optimal design of a catalytic distillation column based on a generic nonequilibrium model (NEQ). The solution strategy for the global optimization combines Simulated Annealing (SA) and Sequential Quadratic Programming (SQP) in order to minimize the objective function. The solution of this MINLP problem yie...

A rate-based simulation method is developed with the correlation for mass transfer rate, which was obtained in our experiments of the homogeneous and heterogeneous ternary distillation with a sieve tray column. The simulation method is applied to the process of ethanol dehydration with benzene, which consists of a dehydrationand an entrainer recovery column. In the simulation study, the effect ...
