Empty sella turcica is a condition in which the pituitary gland absent completely or partially from fossa. The patient may be asymptomatic with empty as an incidental finding, have symptoms of hormones deficiency. Perioperative management these patients depends on and signs hormonal deficiencies replacement treatment.

The tunneling rate, with exact prefactor, is calculated to first order in h̄ for a closed FRW universe filled with perfect fluid violating the strong energy condition. The calculations are performed by applying the dilute-instanton approximation on the corresponding Duru-Kleinert path integral. It is shown that a closed FRW universe filled with a perfect fluid with small violation of strong ener...

Genetically resistant C3H mice have been made phenotypically susceptible to mouse hepatitis virus (MHV) by cortisone (1), cytoxan (2), and eperythrozoon infection (3). There is extensive evidence that cultured macrophages from genetically resistant or susceptible strains of mice reflect the genetic resistance or susceptibility of the host. Yet the effects of cortisone, cytoxan, and epierythrozo...

In the nanochannel flow behavior with respect to expand their applications in modern systems is of utmost importance. According to the results obtained in this study, the condition of nonslip on the wall of the nanochannel is not acceptable because in the nano dimensions, slip depends on different parameters including surface roughness. In this study, keeping the side area roughness, deformatio...

This paper considers an important model of boundary value problem with a condition at infinity namely combined free and forced convection over a plane of arbitrary shape embedded in a fluid-saturated porous medium; this model admits dual solutions, and uses a technique, which is to some extent modification of homotopy analysis method (HAM), in order to obtain dual solutions analytically with hi...

Direct numerical simulation is used to study the mixing of a passive scalar by a vortex ring issuing from a nozzle into stationary fluid. The ‘formation number’ (Gharib et al. J. Fluid Mech. vol. 360, 1998, p. 121), is found to be 3.6. Simulations are performed for a range of stroke ratios (ratio of stroke length to nozzle exit diameter) encompassing the formation number, and the effect of stro...
