adrenocortical carcinoma (acc) is a rare tumor and usually a fatal disease which can develop at any age in either sex. differential diagnosis between malignant and benign adrenal mass is not easy which leads to significant clinical challenge for optimal treatment. here we report a 22-year-old woman diagnosed with primary hyper aldostronism initially but disease relapsed during six months and ma...

It has been observed that dynamo action occurs in the von-Kármán-Sodium (VKS) experiment only when the rotating disks and the blades are made of soft iron. The purpose of this paper is to numerically investigate the role of soft iron in the VKS dynamo scenario. This is done by using a mean-field model based on an axisymmetric mean flow, a localized permeability distribution, and a localized α e...

In seepage problems, the coefficients of permeability in Laplace equation are usually assumed to be constant vs. both space and time; but in reality these coefficients are variable. In this study, the effect of material deformation due to external loads (consolidation) and variation of head in the consolidation process are considered. For the first case, formulation of kx and ky can be defined ...

The development of methods and apparatus for magnetic measurements capable of an accuracy of i per cent makes it necessary to consider factors which have heretofore been considered negligible. One of these factors, the temperature coefficient of magnetic permeability, is the subject of the present paper. Many workers have studied the effects of temperature on the magnetic permeability of iron a...

During the mitochondrial permeability transition, a large channel in the inner mitochondrial membrane opens, leading to the loss of multiple mitochondrial solutes and cell death. Key triggers include excessive reactive oxygen species and mitochondrial calcium overload, factors implicated in neuronal and cardiac pathophysiology. Examining the differential behavior of mitochondrial Ca(2+) overloa...

Analytical investigation of MHD blood flow in a porous inclined stenotic artery under the influence of the inclined magnetic field has been done. Blood is considered as an electrically conducting Newtonian fluid. The physics of the problem is described by the usual MHD equations along with appropriate boundary conditions. The flow governing equations are finally transformed to nonhomogeneous se...

This study investigated the relationship between platelet (PLT) serotonin (5-HT) and intestinal permeability in children with pervasive developmental disorders (PDD). Differential sugar absorption and PLT 5-HT were determined in 23 children with PDD. PLT 5-HT (2.0-7.1 nmol/10(9) PLT) was elevated in 4/23 patients. None exhibited elevated intestinal permeability (lactulose/mannitol ratio: 0.008-...

New procedure for permittivity and permeability extraction of two composite (dielectric matrix + magnetic inclusions), isotropic and homogeneous absorbing material is presented. It calculates mentioned parameters by fitting measured transmission data with Debye relaxation model (for complex dielectric permittivity extraction) and with Lorenzian resonant model (for complex permeability extractio...
