In this paper, natural convection heat transfer of CuO-water Nanofluid within a wavy-walled cavity and subjected to a uniform magnetic field is examined by adopting the lattice Boltzmann model. The left wavy wall is heated sinusoidal, while the right flat wall is maintained at the constant temperature of Tc. The top and the bottom horizontal walls are smooth and insulated against heat and mass....

BACKGROUND Hemodynamic changes in the liver remnant following partial hepatectomy (PHx) have been suggested to be a primary stimulus in triggering liver regeneration. We hypothesized that it is the increased sinusoidal flow per se and hence the shear-stress stimulus on the endothelial surface within the liver remnant which is the main stimulus to regeneration. In order to test this hypothesis w...

To determine the role of the hepatic sinusoidal endothelium in the hepatic disposition of liposomal doxorubicin, we compared the hepatic pharmacokinetics of doxorubicin hydrochloride and the pegylated, liposomal formulation of doxorubicin (Caelyx). The multiple indicator-dilution technique and electron microscopy were used to study the disposition of doxorubicin and liposomal doxorubicin in the...

To explore the control of the peripheral circulation of a nonworking upper limb during leg cycling exercise, blood flow (BF) dynamics in the brachial artery (BA) were determined using a sinusoidal work rate (WR) exercise. Ten healthy subjects performed upright leg cycling exercise at a constant WR for 30 min, followed by 16 min of sinusoidal WR consisting of 4-min periods of WR fluctuating betw...

BACKGROUND In advanced metastatic colorectal adenocarcinoma, the addition of a neo-adjuvant systemic treatment to surgery might translate into a survival advantage, although this is yet to be confirmed by ongoing randomized trials. The objective of this study was to assess the effects of preoperative systemic chemotherapy on the morphology of non-tumoral liver. PATIENTS AND METHODS A large se...

Two families of orthonormal tapers are proposed for multitaper spectral analysis: minimum bias tapers, and sinusoidal tapers {v(k)}, where v (k) n = √ 2 N+1 sin πkn N+1 , and N is the number of points. The resulting sinusoidal multitaper spectral estimate is Ŝ(f) = 1 2K(N+1) ∑K j=1 |y(f+ j 2N+2)−y(f − j 2N+2)| 2, where y(f) is the Fourier transform of the stationary time series, S(f) is the spe...

In this study, the primary breakup of a high-speed diesel jet is investigated using CFD methodology that combines an LES model with VOF technique for free surface capture. Inner-nozzle turbulence and cavitation are simplified as sinusoidal radial velocity given amplitude frequency. The ligament droplet formation process captured, liquid disturbed by velocity, umbrella-shaped crests created. Mea...

The multilevel inverters have become more popular during the recent years. The multilevel inverters are applied in many industrial applications such as static VAR compensators, AC power supplies, drive systems, active power filters, etc. The topologies of multilevel inverter have several advantages such as low distortion in output voltage with relative low switching frequency, low harmonic and ...
