The steady two-dimensional stagnation point flow of a non-Newtonian Walters' B' fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions. 1. Introduction. Some rheologically complex fluids such as polymer solutions, blood, paints, and certain oils cannot be adequately described by the Navier-Stokes...

THE object of this paper is to show the association between initial PULHEEMS grading and eventual medical discharge from the Army, thus taking the study further than an earlier analysis (Rosenbaum, 1957) which confined itself to discharges in the first weeks of service only. These included some for nonmedical reasons, and some below the acceptance standard for service, who were not however allo...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

Cystic pancreatic neoplasms are uncommon, but are being seen more frequently due to the widespread use of crosssectional imaging. In this article, we will address the clinical and imaging features of the more commonly seen neoplasms. Points of differentiation between these neoplasms, the use of cyst fluid analysis and an approach to the incidentally discovered cystic mass will be addressed.

OBJECTIVE To investigate whether the extent of white matter lesions (WML) on fluid attenuated inversion recovery (FLAIR) MRI sequences is an independent risk factor for recurrent stroke, and to document the pattern of acute cerebral infarcts using diffusion weighted imaging (DWI) in patients with different severities of WML. METHODS In a prospective cohort study, 228 consecutive stroke patien...

OBJECTIVE This study was aimed to evaluate relationship between hyperintense vessels (HV) on fluid-attenuated inversion recovery (FLAIR) and artery steno-occlusion related intracerebral collaterals. MATERIALS AND METHODS A total of 233 patients with 260 atherosclerotic lesions in the M1 segment of the middle cerebral artery (MCA) were examined with FLAIR and digital subtraction angiography (D...

OBJECTIVE To evaluate the hydrodynamic changes occurring in cerebrospinal fluid (CSF) flow in cervical spinal stenosis using the spatial modulation of magnetization (SPAMM) technique. MATERIALS AND METHODS Using the SPAMM technique, 44 patients with cervical spinal stenosis and ten healthy volunteers were investigated. The degree of cervical spinal stenosis was rated as low-, intermediate-, o...

An analysis has been carried out for the characteristics of melting heat transfer in the boundary layer flow of third grade fluid in a region of stagnation point past a stretching sheet. The relevant partial differential equations are reduced into ordinary differential system by suitable transformations. The series solutions are developed by homotopy analysis method. It is revealed that an incr...

We establish closed form analytical solutions for the flows of a generalized fluid of complexity two which includes the Navier–Stokes fluid, power-law fluid and the second-grade fluid as special subclasses, in special geometries under the assumption that the flows meet the Navier’s slip conditions at the boundary. We also allow for different boundary conditions at different parts of the boundar...
