Increased implantation and pregnancy rates obtained by placing the tip of the transfer catheter in the central area of the endometrial cavity
(2004-10-01)
The influence of endometrial cavity length (ECL) on implantation and pregnancy rates after 400 embryo transfers was studied prospectively in a population with the indication of IVF/intracytoplasmic sperm injection (ICSI). ...

A genetic neuro-model reference adaptive controller for petroleum wells drilling operations
(2007-12-01)
Motivated by rising drilling operation costs, the oil industry has shown a trend towards real-time measurements and control. In this scenario, drilling control becomes a challenging problem for the industry, especially due ...

Autonomic control of heart rate is virtually independent of temperature but seems related to the neuroanatomy of the efferent vagal supply to the heart in the bullfrog, Lithobathes catesbeianus
(Pergamon-Elsevier B.V. Ltd, 2012-04-01)
Bullfrogs, Lithobathes catesbeianus, bearing a femoral artery cannula were held at 3 temperatures (10,20 and 30 degrees C) for 24 h. Changes in heart rate were recorded before and after injection of cholinergic and adrenergic ...

Systemic risk, dollarization, and interest rates in emerging markets: a panel-based approach
(Oxford Univ Press, 2009)
This study investigates the impact of systemic risks and financial dollarization on real interest rates in emerging economies. Higher systemic risks induce both higher real interest rates and increased dollarization. Using ...
