A New Laboratory Fermenter for Yeast Production Investigations

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

Optimization of A Fed-Batch Fermenter Producing Baker’s Yeast Using Simulated Annealing Method

Modeling of fermentation processes is so complicated and uncertain; therefore it is necessary to provide a robust and appropriate dynamic optimization method. In order to obtain the maximum amount of yeast (Saccharomyces cerevisiae), the bioreactor must be operated under optimal conditions. To determine substrate feeding in a fed-batch bioreactor, a simulated annealing (SA) approach was examine...

Laboratory and Field Investigations with Difenacoum, a Promising New Rodenticide

Difenacoum is a new rodenticide recently introduced on the British market; it is one of the most potent of a series of hydroxycoumarin-based anticoagulants. Difenacoum is effective against laboratory rats and mice resistant to conventional anticoagulants and has a marked selectivity in favour of non-target species. Vitamin K1 is an effective antidote and the hazard of secondary poisoning is min...

Fodder Yeast Production: a New Approach for Distillery Vinasse Treatment

Online Laboratory Investigations

Critical Care Medicine www.ccmjournal.org e65 Objective: Cyclic recruitment and derecruitment of atelectasis can occur during mechanical ventilation, especially in injured lungs. Experimentally, cyclic recruitment and derecruitment can be quantified by respiration-dependent changes in Pao2 (ΔPao2), reflecting the varying intrapulmonary shunt fraction within the respiratory cycle. This study inv...
