Chronic inflammatory demyelinating polyneuroradiculopathy (CIDP) is an immune mediated disorder characterized by progressive developing or relapsing symmetrical motor or sensory symptoms in more than one limb over a period of two months. Achalasia, as a primary esophageal motility disorder, is also characterized by increasing the tone of lower esophageal sphincter, absence or incomplete sphinct...

Introduction: Noise-induced hearing loss (NIHL) is a major problem in industrialized and developing countries. Trend of industrialization and lack of proper protective equipment lead to an increased frequency of noise-related disorders especially NIHL. This study was conducted to investigate noise pollution and the frequency of NIHL in workers of one of the ceramic industries. Materials and ...

effects of three pressure reduction rates (prr) of 103 pa s-1, 197 pa s-1, and 347 pa s-1 on temperature distribution and variation, moisture content, and sensory quality of steamed stuffed buns were investigated after vacuum cooling. the distributions and variations of surface temperatures were determined by the thermal infrared imaging method. the temperature profiles presented significant di...

BACKGROUND Epidemiology of acute stroke in developing countries differs from that in the developed world, for example, the age at stroke, risk factors, subtypes of stroke and prognosis. Hypertension remains a dominant risk factor and prognostic indicator in patients with stroke in all communities. The risk of stroke is directly related to elevations of blood pressure. A number of clinical studi...

Past efforts to reduce the airfoil count in low pressure turbines have produced high lift profiles with unacceptably high endwall loss. The purpose of the current work is to suggest alternative approaches for reducing endwall losses. The effects of the fluid mechanics and high lift profile geometry are considered. Mixing effects of the mean flow and turbulence fields are decoupled to show that ...

ABSTRACT This paper studies the performance of the unrestricted estimator (UE) and preliminary test estimator (PTE) of the slope parameter of simple linear regression model under linex loss function. The risk functions of both the UE and PTE are derived. The moment generating function (MGF) of the PTE is derived which turns out to be a component of the risk function. From the MGF the first two ...

We introduce a discrete element simulation for the hydraulic fracture process in a petroleum well which takes into account the elastic behavior of the rock and the Mohr-Coulomb fracture criterium. The rock is modeled as an array of Voronoi polygons joined by elastic beams, which are submitted to tectonical stresses and the hydrostatic pressure of the fracturing fluid. The fluid pressure is trea...
