Appropriate length of artery was then undermined.
Simplification of our system is reached using non-dimensional quantities (9), very small Reynolds number, (R_{e}), and R_{ 0}ll l where l is the finite length of artery.
In the present model, a length of artery was studied; thus, we assumed that only 6000 magnetic nanoparticles were inserted into the arterial flow (domain 2 in Fig. 2).
The capture efficiency for a length of artery is defined as the fraction of magnetic nanoparticles attracted by the magnetic field towards the vessel wall, varepsilon=left(frac{varepsilon_{text{in}}-varepsilon_{text{out}}}{varepsilon_{text{in}}}right times 100,%, (25).
They found that when a length of artery is excised from a body, the artery contracts.
The existence of these residual stresses may be demonstrated by the so-called opening angle experiment, first proposed by Chuong and Fung (1986), in which a short length of artery in the form of a ring is cut radially.
At a pullback rate of 1.0 mm/s (or 1.5 mm/s) and 15 frames/s, a video sequence of cross-sectional OCT images over a 3 cm (or 4.5 cm) length of artery was obtained.
The justification for such models typically arise due to the significantly long wavelength associated with the system in comparison to the lengths of arteries in the networks.
10– 15, 16, 18, 18 All segments were analyzed at 1-mm intervals along the length of the arteries.
The compliance of the peripheral circulation and the length of the arteries were not changed, as 1) previous studies have shown that these parameters do not change the pressure and flow waveforms significantly (28, 54); and 2) Sugawara et al. (44) showed that aortic tortuosity is mainly due to an elongation of the ascending aorta and has little impact on PWV measurements.
