Are Uterine and Ovarian Artery Doppler Velocimetry Values Good Pregnancy Predictors in Clomiphene Citrate Cycles?
Background We conducted this prospective study to evaluate the prognostic significance of uterine and ovarian artery Doppler velocimetry in clomiphene citrate (CC) cycles. MaterialsAndMethods A total of 80 patients with unexplained infertility were given 100 mg/day of CC from day 3 to day 7 of their cycles in this current prospective study. On cycle day 3, before administration of CC, each pati...
متن کاملMicron-Resolution Velocimetry Techniques
This paper examines various techniques that have been developed to measure flow fields in microfluidic devices with 10 – 10 micron-scale spatial resolution. These techniques include Scalar Image Velocimetry (SIV), Laser Doppler Velocimetry (LDV), and Particle Image Velocimetry (PIV). Advantages and disadvantages of these techniques are presented. PIV results are presented for a liquid flow thro...
متن کاملAnalysis of Pseudo-Turbulence Flow Induced by Bubble Periodic Formation in Non-Newtonian Fluids
Laser Doppler Velocimetry (LDV) has been employed to determine pseudo-turbulence characteristics of the flow field around bubble train forming in non-Newtonian caboxymethylcellulose (CMC) aqueous solution at low gas flow rate condition. The Reynolds stress and turbulent intensity of the liquid were investigated by means of Reynolds time-averaged method. The experimental results show that ax...
متن کاملReactivity of the human retinal circulation to darkness: a laser Doppler velocimetry study.
Bidirectional laser Doppler velocimetry (LDV) and fundus photography were applied to investigate the effects of light and darkness on retinal blood flow. Blood flow had increased by an average of 67% after 5 min of darkness. This increase persisted for periods of darkness as long as 80 min (the longest period tested). The magnitude of this elevation, its time course, and its neutralization by t...
متن کاملPreliminary experiences with laser Doppler velocimetry for the determination of amputation levels.
Laser Doppler velocimetry is a newly available technique for the continuous and non-invasive measurement of capillary perfusion. The technique is presented and preliminary results of its use in the evaluation of amputation levels in 16 patients discussed.
متن کامل8th Aiaa Aerospace Ground Testing Conference Development of Doppler Global Velocimetry for Wind Tunnel Testing Development of Doppler Global Velocimetry for Wind Tunnel Testing Introduction
The development of Doppler global velocimetry is described. Emphasis is placed on the modifications necessary to advance this nonintrusive laser based measurement technique from a laboratory prototype to a viable wind tunnel flow diagnostics tool. Several example wind tunnel flow field investigations are described to illustrate the versatility of the technique. Flow conditions ranged from incom...
