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...

We have made a line identification list and derived preliminary abundances for the extreme peculiar star HD 101065 (Przybylski’s star), based on a spectrum recorded at ESO with the CASPEC spectrograph. The line list covers the range 5445–6587 Å. We find iron to be mildly deficient, possibly not as much as an order of magnitude, while the lanthanide rare earths are enhanced by some 4 dex. Abunda...

The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...

2014 When a muon is implanted in a rare earth host the electric field gradient created by the muon charge will affect the orientation of neighbouring rare earth moments and so will lead to strong dipolar fields at the muon site. J. Physique LETTRES 45 (1984) L-27 L-29 ler 3ANVIER 1984, Classification Physics Abstracts 76.90 The hyperfine field has been measured at positive muons in a number of ...

The spin-lattice relaxation time τ SL is a key quantity both for the dynam-ical response of ferromagnets excited by laser pulses and as the speed limit of magneto-optical recording. Extending the theory for the electron param-agnetic resonance of magnetic impurities to spin-lattice relaxation in ferro-magnetic rare earths we calculate τ SL for Gd and find a value of 48 ps in very good agreement...

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...

in this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited fecu/cu thin films was investigated. the films were deposited on au2pdag/glass substrates using electrodeposition technique in potentiostatic control. the magnetic fields of 5000 and 7000 oe were applied on deposition bath during deposition. two series of thin films were prepared...
