Structural as well magnetization studies have been carried out on graphite samples irradiated by neutrons for over 50 years in the CIRUS research reactor at Trombay, India. Neutron diffraction reveal that defects are not annealed and remain significant up to high temperatures much greater than 653 K where Wigner energy is completely released. We infer remnant may be intralayer Frenkel defects, ...
The 4-d SU(2) lattice gauge theory is simulated in the minimal Coulomb gauge which aims to maximize the traces of all links in three directions. Fourth-direction links are interpreted as spins in a Heisenberg-like model with varying interactions. These spins magnetize in 3-d hyperlayers at weak coupling, breaking a remnant gauge symmetry, as well as the Polyakov-loop symmetry. They demagnetize ...
Although the basic question of ablative threshold dose for ablation of thyroid remnant after surgery yet remains unanswered. But radioiodine therapy is being used as a standard method of treatment. In present research, treatment responces for 100 patients with thyroid cancer treated with 3660 MBq of ¹³¹I were studied. Significant response differences between female group (66%) and male group (3...
Samarium doped BiFeO3 compounds having nano-size crystallites were prepared by the ethylene glycol assisted sol-gel synthesis method. X-ray diffraction and SEM measurements as well Raman spectroscopy FTIR experiments used to clarify an evolution of crystal structure on microscopic local scale levels in formula Bi1-xSmxFeO3, where 0 = x ≤ 1. Magnetization along with structural data determine a c...
Molecule-specific noncovalent bonding on cell surfaces is the foundation for cellular recognition and functioning. A major challenge in probing these bonds is to resolve the specific bonds quantitatively and efficiently from the nonspecific interactions in a complex environment. Using force-induced remnant magnetization spectroscopy (FIRMS), we were able to resolve quantitatively three differen...
bond failure of brackets during orthodontic treatment is a common problem; which results in treatment interference, increased treatment time and prolonged clinical time for rebonding of failed brackets. the purpose of this study was to evaluate the effects of coca-cola and a non-alcoholic beer on the shear bond strength and adhesive remnant index (ari) of orthodontic metal brackets in vitro.eig...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
We report the detailed structural characterization and magnetic investigation of nanocrystalline zinc ferrite nanoparticles supported on a silica aerogel porous matrix which differ in size (in the range 4-11 nm) and the inversion degree (from 0.4 to 0.2) as compared to bulk zinc ferrite which has a normal spinel structure. The samples were investigated by zero-field-cooling-field-cooling, therm...
The clear understanding of exchange interactions between magnetic ions in substituted BiFeO3 is the prerequisite for the comprehensive studies on magnetic properties. BiFe0.5Mn0.5O3 films and BiFeO3/BiMnO3 superlattices have been fabricated by pulsed laser deposition on (001) SrTiO3 substrates. Using piezoresponse force microscopy (PFM), the ferroelectricity at room temperature has been inferre...
