In this paper we propose a simulation model combining two processes of different origin (the production process and the information flow of maintenance work-orders) in one model in order to investigate how the interaction between the processes affect the performance of the production system, as well as to define the optimization opportunities. The proposed approach aims to extend the capabiliti...

In the present study, Streptomyces gulbargensis and its mutant form, S.gulbargensis mu24, immobilized on polyurethane foam were investigated for the production of L-asparaginase using groundnut cake extract as medium. The medium with an initial pH of 8.5 was inoculated with free and immobilized cells separately and then subjected to fermentation by incubation at 40oC and shaking at 200 rev/min....

the present study aimed to compare academic performance and self-concept of physical education and sport sciences course between conventional and distance educational systems. the statistical population included all physical education undergraduate students at ardabil state universities in 2012-2013 academic years (n=234). using stratified random sampling method, 100 students were selected and ...

The new method of direct fermentation was applied to tarhana production. Chemical and sensory differences in samples between conventional techniques were determined. A total 72 volatile compounds mixes detected by headspace analysis during fermentation. Fifteen these from aldehyde group, 13 ketone 10 alcohol 7 alkane 5 acid ester 4 terpene group others. bilateral interactions or sampling times ...
