In the present work microstructural evolution of A356 Aluminum alloy using an inclined cooling plate casting process for thixoforming feedstock production is investigated. The resultant microstructure was evaluated and compared with those of the same alloy produced by the conventional casting process, i.e. directly cast in the same mold without using an inclined cooling plate. It was found that...

[Purpose] The present study assessed the effects of using an unstable inclined board on the active and passive ankle range of motion in patients with ankle stiffness. [Subjects] The study included 10 young female patients with ankle stiffness. [Methods] The patients were divided into the following two groups: a group that performed ankle dorsiflexion stretching exercises using a wooden inclined...

Natural convection of Bingham plastics in a cavity with differentially heated walls and an internal heat source is investigated numerically. The governing dimensional non-dimensional macroscopic equations are presented, the constitutive equation written based on exact model. implemented lattice Boltzmann method explained showed how to derive presented equations. code validated verified against ...

CT scans of the type braincase Limaysaurus tessonei (MUCPv-205) allowed first study endocranial cavities (brain and inner ear) for this South American taxon. Comparisons cranial endocast L. with other sauropods indicate that 1) rebbachisaurids are more similar to each than Nigersaurus, 2) certain association traits present in all known rebbachisaurid endocasts, such as lack an enlarged dorsal e...

The cross-sectional echocardiographic demonstration of the "goose-neck" deformity is described in four patients with endocardial cushion defect. The diagnosis was confirmed in each patient by left ventricular angiocardiogram. The subxiphoid approach of cross-sectional echocardiography in diastole allowed visualization of an elongated, narrowed, and somewhat horizontally inclined configuration o...

A variational formulation of the standard MAC scheme for the approximation of the Navier-Stokes problem yields an extension of the scheme to general 2D and 3D domains and more general meshes. An original discretization of the trilinear form of the nonlinear convection term is proposed; it is designed so as to vanish for discrete divergence free functions. This property allows us to give a mathe...

Oral malignant melanoma (OMM) is a rare tumor of the oral cavity with very poor prognosis. This paper aims to present a rare case and a comprehensive review of clinical feature and treating methods. We report a case of a giant gingival malignant melanoma with mandible invasion and regional lymph node metastases. The tumor was dissected 1.5 cm beyond the tumor margins and hemimandibulectomy with...

A new approach based on the finite-difference technique has been developed to study the steady incompressible Navier-Stokes equations in the laminar region, where the domain is partially bounded by a free surface. The nonstaggered fractional step method is used to solve the flow equations written in terms of primitive variables. The physical domain is transformed to a rectangle by means of a nu...
