role of labor induction has increased in the last decade due to the ‎early detection of fetal jeopardy. although very useful, oxytocin alone is not always successful for induction of ‎labor. in a randomized clinical ‎trial we compared vaginal dinoprostone plus oxytocin with oxytocin alone for ‎induction of labor in 91 ‎pregnant women at 40 weeks or greater gestation with bishop scores ≤ 4. fort...

The fluid flow in the runner of a hydraulic turbine has serious uncertainties. sealing failure magnetorheological (MR) device main shaft hydroturbine, caused by sudden change speed, always been difficult topic to research. This study first derives MR seal pressure and unbalanced curl equations hydroturbine shaft, then analyzes friction heat under different rotational speed mutation conditions t...

to evaluate the maternal serum dehydroepiandrosterone (dhea) sulfate levels as a factor influencing labor ‘efficiency’ at term and unsuccessful labor induction. this is a prospective study. in this study the mean (± standard error) maternal serum dhea sulfate levels of 90 singleton pregnant women in 3 groups with spontaneous labor, need for augmentation and need for induction were compared.preg...

Induction machines are the working horses in a lot of industries. Inter-turn short-circuit (ITSC) fault is one most common failure modes taking place them. It can generate large currents that lead to local temperature rise faulty stator slot, which deteriorates performance machine or even cascades complete breakdown. This article focuses on developing transient thermal models for an induction u...

BACKGROUND The Infectious Diseases Society of America published in 2000 practical guidelines for the management of cryptococcosis. However, treatment strategies have not been fully validated in the various clinical settings due to exclusion criteria during therapeutic trials. We assessed here the optimal therapeutic strategies for severe cryptococcosis using the observational prospective Crypto...

We analyze a system-level model for lytic repression of phage in E. coli using reliability theory, showing that the repressor circuit comprises four redundant components whose failure mode is prophage induction. Our model reflects the specific biochemical mechanisms involved in regulation, including long-range cooperative binding, and its detailed predictions for prophage induction in E. coli u...

This work presents, demonstrates and analyzes a property that relates the transient response of stator and rotor currents to the speed of induction motors and their parameters. The straightforward application of this property allows determining the rotation speed of the motor and detecting a failure or variation of its parameters. This property is demonstrated analyzing the induction motor mode...
