This paper presents the effect of centrifugal load in functionally graded (FG) hollow sphere subjected to uniform magnetic field. Analytical solution for stresses and perturbation of the magnetic field vector are determined using the direct method and the power series method. The material stiffness, the magnetic permeability and the density vary continuously across the thickness direction accor...

introduction: orthogonal radial fields are those in which the central axes are perpendicular to each other. an example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. the m...

Introduction: The use of two arterial conduits for CABG is rapidly increasing. The second arterial conduit to LITA is usually RITA or radial artery. We sought to compare outcomes when either RITA or radial artery is exclusively used as a Y composite graft to LITA for total arterial revascularization. Material and methods:  We retrospectively analyzed 231 ...

Background: The radial artery is an essential artery supplying the structures in the forearm. Variations in the radial artery concerning its origin, course, branching pattern, and mode of termination have been commonly reported. The high origin of the radial artery from either brachial or axillary artery was detected in numerous studies. Clinically-radial artery is used in cardiac catheterizati...

The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

Nickel-titanium alloy (Nitinol) is an excellent shape memory (SMA) for microelectro-mechanical systems (MEMS) particularly in biomedical applications owing to its three features effect (SME), superelasticity, and biocompatibility. The temperature-dependent material transformation properties of Nitinol SMAs make conventional machining difficult. Micro-ECM, a non-conventional process conductive m...

Background: Some of the Mason type I fractures cannot be detected on early radiographic images. These occultfractures are considered as a diagnostic challenge for physicians. Our aim was to determine the value of bedsideultrasonography for the detection of Mason I radial head fractures that are non-visible in early X-ray’s.Methods: A prospective blind single-center diagnostic study was conducte...

Background: Transradial access is one of the main access techniques in angiography. This method is technically more difficult as it is associated with radial artery occlusion. Radial artery cannulation from the dorsal surface of the hand in the snuffbox area has been introduced as a suitable solution to overcome some of the disadvantages of the standard radial artery method. This study was cond...

In this paper, ultrasonic vibration–assisted electrical discharge machining (UEDM) is used to process SiCp/Al composite materials in order achieve a higher material removal rate (MRR) and lower surface roughness, width overcut, relative tool wear (RTWR). On the basis of studying erosion mechanism EDM material, flow field simulation study was carried out using FLUENT software. The results gap sh...
