The present study reports normal values for peak expiratory flow rates in children from 4 1/2 to 18 1/2 years of age. A close correlation between flow rates and height was found for both sexes. Serial peak flow
Close to the wall both the mean velocity and the shear stress differ from the measurements while the agreement is very good towards the outside of the boundary layer. The last plot for the Reynolds normal stresses shows again that the modification in the pressure-strain correlation is ...
For all controls together, the averaged peak velocity was 4.2 +/- 1.5 cm/s in rostral and -7.8 +/- 4.9 cm/s in caudal direction; for the flux it was 0.16 +/- 0.10 cm3/s in rostral and -0.29 +/- 0.19 cm3/s in caudal direction. Phase-contrast measurements were significantly ...
These preliminary data indicate that TCCS and particularly contrast-enhanced TCCS permit identification and blood flow measurements within the deep and occasionally, the superficial venous system. TCCS may contribute to an assessment of hemodynamic repercussions of venous thrombosis and may indicate the ...
These guidelines now apply to all adults. Previously, people younger than age 65 had a threshold of 140/90, and 150/80 for those 65 and older. Because blood pressure tends to increase as you age, it’s important to pay close attention to your measurements, especially as you get older. ...
At the same time, the experimental conditions and instrumental parameters are consistent across all measurements. Fig. 4 The obtained LIF spectra of the normal and inflammatory classes. Note that for each spectrum, each data point on the plot represents the mean of 25 individual intensity ...

To investigate whether changes in circulating serum vascular endothelial growth factor (VEGF) concentrations during the menstrual cycle are associated with changes in blood flow within the ovaries and uterus. PATIENTS AND MEASUREMENTS Serum VEGF concentrations were measured and pulsed and colour Doppler blo...

The initial aperture can be determined by the physical measurements of the surface topography, where the upper and lower halves could be digitised with profilometer, optical, photogrammetry, or laser scanning methods. Then, the two reference planes are merged into the same coordinate system, called ...
