tannase has several important applications in food, feed, chemical and pharmaceutical industries. in the present study, production of tannase by mutant strain, penicillium sp. ez-zh390, was optimized in submerged fermentation utilizing two statistical approaches. at first step, a one factor at a time design was employed to screen the preferable nutriments (carbon and nitrogen sources of the med...

incorporation of functional foods and nutraceuticals such as carotenoids which suffer from poor water solubility and low bioavailability into nano-sized delivery systems can improve their solubility, stability and oral bioavailability. the aim of this study was to prepare β-carotene nanodispersion and investigate the effects of preparation parameters by means of response surface methodology usi...

conclusions we found ccd and rsm very effective in optimizing hib culture conditions, and hib biomass production was greatly influenced by ph and incubation temperature. therefore, optimization of the growth factors to maximize hib production can lead to 1) an increase in bacterial biomass and prp productions, 2) lower vaccine prices, 3) vaccination of more susceptible populations, and 4) lower...

Methodolog...

The application of formal techniques can contribute much to the quality of software, which is of utmost importance for safety-critical embedded systems. These techniques, however, are not easy to apply. In particular, methodolog-ical guidance is often unsatisfactory. We address this problem by the concept of an agenda. An agenda is a list of activities to be performed for solving a task in soft...

|This paper presents a statistical approach to developing multimodal recognition systems and, in particular, to integrating the posterior probabilities of parallel input signals involved in the multimodal system. We rst identify the primary factors that innuence multimodal recognition performance by evaluating the multimodal recognition probabilities. We then develop two techniques, an estimate...

Any organization that intends to use component-based software development, like outsourcing software, must first evaluate existing components against system requirements find the best fit among many alternatives. As a result, there should be mechanism help with decision-making. Our proposed methodology tries select alternative available components, using decision-making approach. an integrated ...
