Blood Velocity ond Volumetric Flow Rote in Humon Retinal Vessels

The distributions of blood velocity and volumetric flow rate in individual vessels of the normal human retina were determined as a function of vessel diameter. The mean velocity of blood, Vmean, was calculated from the centerline velocity measured by bidirectional laser Doppler velocimetry (LDV). Volumetric flow rate was determined from Vmean and the vessel diameter, D, measured from monochroma...

Hemodynamic flow visualization of early embryonic great vessels using μPIV.

Microparticle image velocimetry (μPIV) is an evolving quantitative methodology to closely and accurately monitor the cardiac flow dynamics and mechanotransduction during vascular morphogenesis. While PIV technique has a long history, contemporary developments in advanced microscopy have significantly expanded its power. This chapter includes three new methods for μPIV acquisition in selected em...

Study of Volumetric Flow Rate of a Micropump Using a Non-classical Elasticity Theory

The purpose of this research is to study the mechanical behavior of a micropump with clamped circular diaphragm which is the main component of drug delivery systems. In this paper, the non-linear governing equations of the circular microplate using Kirchhoff thin plate theory was been extracted based on the modified couple stress (MCST) and classical (CT) theories. Then, the non-linear equation...

Transposition of the great vessels.

The vast majority of cases of transposition of the great vessels can be diagnosed in the first few weeks of life with electrocardiogram, x-ray and fluoroscope. The clinical pattern and the diagnostic features are described in detail. The degree of cyanosis, the characteristic heart shape and progressive increase in size coupled with generous hilar shadows all suggest this diagnosis. A new sugge...
