Org NC 45 60-80 microgram kg-1 was administered to 20 pregnant women undergoing general anaesthesia for Caesarean section. Org NC 45 plasma concentrations were measured fluorimetrically in samples of maternal, venous and arterial cord blood obtained at delivery. The venous cord to maternal concentration ratio averaged 11% and was not influenced by the interval between induction and delivery. Th...

About 20% of the electricity produced in the world is consumed in rotary equipment for conveying fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study is to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stati...

The averaged switch modeling technique unifies the modeling of PWM and resonant dc-dc converters, low-harmonic rectifiers, and inverters in a simple manner. This technique is briefly reviewed, and recent results in modeling current-programmed dc-dc converters, integrated single-phase low-harmonic rectifier-regulators, and single-switch three-phase lowharmonic rectifiers are described. A circuit...

We study a simple learning algorithm for binary classification. Instead of predicting with the best hypothesis in the hypothesis class, that is, the hypothesis that minimizes the training error, our algorithm predicts with a weighted average of all hypotheses, weighted exponentially with respect to their training error. We show that the prediction of this algorithm is much more stable than the ...

rabbits following continuous intrayenous infusion of 20rnglkg oyer a 60 minute period, and the results were compared in a cressover test. 2} The concentration of CLDM phosphate in the oral tissues of rabbits following continuous intravenous drip infusion of 20mg/kg over a 60 minute period was found to be a maximum in the submaxillary gland {21.1nglg), followed br the liver, submaxillary lymph n...

sedimentation is one of the most important problems in harbors that results in considerable economic costs. harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. in the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...
