an attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic poiseuille flow of phan-thein-tanner (ptt). series solution of magneto hydrodynamic (mhd) flow is developed by using homotopy perturbation method (hpm). results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. the results obtained reveals ma...

Free vibration of a simply-supported magneto-electro-elastic doubly-curved nano-shell is studied based on the first-order shear deformation theory in the presence of the rotary inertia effect. To model the electric and magnetic behaviors of the nano-shell, Gauss’s laws for electrostatics and magneto statics are used. By using Navier’s method, the partial differential equations of motion are red...

We experimentally studied the magneto-photocurrents generated by direct interband transition in InAs/GaSb type II superlattice. By varying the magnetic field direction, we observed that an in-plane magnetic field induces a photocurrent linearly proportional to the magnetic field; however, a magnetic field tilted to the sample plane induces a photocurrent presenting quadratic magnetic field depe...

The magnetic nanoparticle composite NiFe2O4 has traditionally been studied for high-frequency microwave absorption with marginal performance towards low-frequency radar bands (particularly L and S bands). Here, NiFe2O4 nanoparticles and nanohybrids using large-diameter graphene oxide (GO) sheets are prepared via solvothermal synthesis for low-frequency wide bandwidth shielding (L and S radar ba...

Magneto-plasmonics is a designation generally associated with ferromagnetic-plasmonic materials because such optical responses from nonmagnetic materials alone are considered weak. Here, we show that there exists a switching transition between linear and nonlinear magneto-optical behaviors in noble-metal nanocolloids that is observable at ultralow illumination intensities and direct current mag...

There is a growing experimental interest in coupling cavity photons to the cyclotron resonance excitations of electron liquids in high-mobility semiconductor quantum wells or graphene sheets. These media offer unique platforms to carry out fundamental studies of exciton-polariton condensation and cavity quantum electrodynamics in a regime, in which electron-electron interactions are expected to...

A chromosomal translocation uniquely associated with chronic myeloid leukemia leads to the formation of a chimeric gene, bcr-abl, on the Phil adelphia chromosome. The BRC-ABL protein displays an uncontrolled tyrosine kinase activity similar to that seen with the transforming onco gene of the Abelson murine leukemia (ABL) virus (\-abl). An interleukin 3 dependent cell line, IC.DP, has been trans...

introduction: the information recorded in medical sheets can help us facilitate the treatment process, recognize the quality of performance of the medical staff, plan health care programs and make accurate and appropriate decisions. this study intends to compare the quality of recording information in admission and summary sheets of three hospitals in isfahan in the first six months of 1381. ma...

The structure and evolution of protoplanetary disks (PPDs) are largely governed by disk angular momentum transport, mediated magnetic fields. In the most observable outer disk, PPD gas dynamics is primarily controlled ambipolar diffusion as dominant non-ideal magnetohydrodynamic (MHD) effect. this work, we study in PPDs conducting a set global 3D MHD simulations with net poloidal flux, using At...

In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...
