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 article, an exact levy solution is presented for bending analysis of a functionally graded (FG) annular sector plate. The governing equilibrium equations are obtained based on the classical plate theory. Introducing an analytical method for the first time, the three coupled governing equilibrium equations are replaced by an independent equation in term of transverse deflection. This equ...

This paper is the first of a two-part study concerning measurement and prediction of saturated flow boiling heat transfer in a water-cooled micro-channel heat sink. In this paper, new experimental results are discussed which provide new physical insight into the unique nature of flow boiling in narrow rectangular micro-channels. The micro-channel heat sink contained 21 parallel channels having ...

BACKGROUND Tissue Doppler imaging enables qualitative and quantitative assessment of myocardial function of the left and right ventricles. AIM To compare systolic longitudinal mitral and tricuspid annular velocities in a congestive heart failure (CHF) patient group with clinical suspicion of pulmonary embolism (PE). METHODS Fifty-five consecutive CHF patients with a history of abrupt onset ...

where the expression following the first equality is the force in the spring and that following the second is the frictional resistance to sliding of the block (both expressed for a block of unit area). The load point velocity vo is the product of the imposed rate of tectonic strain rate γ̇ in the crustal block and the characteristic length of the block. The effective spring stiffness k is the s...

The pathophysiology of reduced maximum expiratory flow in a canine model of pulmonary emphysema was studied, and the results interpreted in terms of the wave-speed theory of flow limitation. According to this theory, maximum expiratory flow is related both to the cross-sectional area and compliance at an airway site where a critical gas velocity is first reached ("choke-point") and to gas densi...

FIG. 1. EOF of the zonal-mean surface pressure in the CKV model (solid), zonal mean of the nonzonally averaged surface pressure in the CKV model (dashed), and zonal mean of the sector EOF shown in CKV’s Fig. 11a (dotted–dashed). We thank Dr. Robinson for his comments (Robinson 2004). Robinson argues that the results of Cash et al. (2002, hereafter CKV) are not inconsistent with the presence of ...
