In this paper, a semi-analytical solution for magneto-thermo-elastic problem in an axisymmetric functionally graded (FG) hollow rotating disk with constant thickness placed in uniform magnetic and thermal fields with heat convection from disk’s surfaces is presented. Solution for stresses and perturbation of magnetic field vector in a thin FG rotating disk is determined using infinitesimal theo...

Fe3O4 nanofluid fully developed forced convection inside a copper tube is empirically investigated under the effect of a magnetic field. All of the investigations are performed under laminar flow regime (670≤Re≤1700) and thermal boundary conditions of the tube with uniform thermal flux. The tube is under the effect of a magnetic field in certain points. This research aims to study the effect of...

In this research, Effect of thermal treatment on beneficiation of low-grade laterite nickel by calcination-magnetic separation method was studied. In order to determine the components and elements of the sample, to recognize the main and minor minerals and their bond, and phase transformation caused by thermal treatment, Chemical analysis (XRF and ICP), microscopic studies and XRD analysis ...

Novel magnetic biochar has been successfully synthesized by using microwave technique, using discarded materials such as Empty Fruit Bunch (EFB). The optimized conditions for the best novel magnetic biochar synthesis are at 900 w reaction power, 20 min reaction time, and impregnation ratio 0.5 (biomas:FeCl3) The details physical and chemical analyses of novel magnetic biochar wer...

The entanglement at zero-temperature is studied in a two-qubit XZ spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. We have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. It is shown that the ground state of thesystem depends on the strength of exchange coupling. We have shown that the analytical relation oft...

The microtubes are important structures in nano electromechanical system .in this study a nonlocal model is presented to investigate the static torsion behavior of microtubes made of bi-directional factionally graded material (BDFGM) subjected to a longitudinal magnetic field. Mechanical properties of BDFGM microtube varies in the radial and longitudinal direction according to an arbitrary func...

background: hydatidosis it is a zoonotic disease which is caused by the larval stages of different species of the tapeworms (cestoda) of genus echinococcus. currently, the surgery is most definitive method of treatment for hydatid cyst, but always there is the risk of leakage or rupture during the surgery, therefore it is considered unreliable method. methods: protoscoleces of hydatid cysts wer...

background: so far, non-invasive diagnostic approaches such as ultrasound, magnetic resonance imaging, or blood tests do not have sufficient diagnostic power for endometriosis disease. lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. objective: the present study focuses on the identification of predictive biomarkers i...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...
