Raschig Super-Pak is a novel development in structured packing product technology that is fundamentally different to the well known corrugated perforated or nonperforated, textured sheet metal structured packings. It comprises of a systematic sequence of smooth sinusoidal waves above and below the plain of the metal sheet. Total reflux distillation tests with Raschig Super-Pak 300 were conducte...

This paper is concerned with the analysis of peristaltic motion of a Jeffrey fluid in a tube with sinusoidal wave travelling down its wall. The effect of rotation, porous medium, and magnetic field on peristaltic transport of a Jeffrey fluid in tube is studied. The fluid is electrically conducting in the presence of rotation and a uniform magnetic field. An analytic solution is carried out for ...

In this review paper the sound propagation in a human vocal tract is analyzed. The sound pressure and the volume velocity in the tract are evaluated when a unit-amplitude, monochromatic, sinusoidal volume velocity is sent from the glottis towards the lips. The unique solution to the inverse problem is outlined, where the cross-sectional area of the vocal tract as a function of the distance from...

We analyze experimentally and theoretically mechanical oscillation within an optical cavity stimulated by the pressure of circulating optical radiation. The resulting radio frequency cavity vibrations (phonon mode) cause modulation of the incident, continuous-wave (cw) input pump beam. Furthermore, with increasing cw pump power, an evolution from sinusoidal modulation to random oscillations is ...

Pharmacological therapy of portal hypertensión can be accomplished according to different objectives. Among them, pre-primary prophylaxis aims to avoid / delay esophageal varices development while the target of primary prophylaxis is protection against first variceal bleeding. Hepatic venous pressure gradient (HVPG) measurement closely reflects portal pressure in most liver diseases whith predo...

ABSTRACT. Probability theory is applied to the problem of estimating the ratio of the amplitudes of two sinusoids in nuclear magnetic resonance data. The posterior probability-density for the amplitude ratio is derived independent of the phase, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability-density function is then applied in ...

Sound morphing is one of the successful synthesis technologies for recent computer music, and several studies have been reported on this subject. We have proposed a sound morphing algorithm based on a sinusoidal model. In this paper, a correspondence search algorithm is improved, which is core technology of morphing based on a sinusoidal model. Then wider applications of the algorithm are intro...

Probability theory is applied to the problem of estimating the amplitudes of the sinusoids in nuclear magnetic resonance data containing two exponentially decaying sinusoids. The posterior probability-density of one of the amplitudes is derived independent of the phases, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability-density f...

1. Normal liver anatomy and function The normal liver is constituted by 2 lobes, with a weight of approximately 1400-2100 g and holds approximately 13% of the body's blood supply, with a dual blood perfusion via the hepatic artery (25%) and portal vein (75%). The liver parenchyma is organized into small units (acini) that are characterized by an incoming blood supply from portal tracts (branche...
