    Effect of pressure on the electronic structure of hcp Titanium

    Full text link
    The effect of pressure on the hexagonal close-packed structure of titanium is investigated. The lattice parameters of the equilibrium structure were determined in terms of the Gibbs free energy using the Epitaxial Bain Path method. When this process was repeated for several pressures, the effect of pressure on the lattice parameters was revealed. The calculated lattice parameters were in good agreement with the experimental and theoretical results. The effects of pressure on parameters depending on the electronic structure such as conductivity and resistivity in the ground state were also investigated up to 30 GPa using density functional theory.Comment: 7 pages, 7 figure

    Axial anomaly of QED in a strong magnetic field and noncommutative anomaly

    Get PDF
    The Adler-Bell-Jackiw (ABJ) anomaly of a 3+1 dimensional QED is calculated in the presence of a strong magnetic field. It is shown that in the regime with the lowest Landau level (LLL) dominance a dimensional reduction from D=4 to D=2 dimensions occurs in the longitudinal sector of the low energy effective field theory. In the chiral limit, the resulting anomaly is therefore comparable with the axial anomaly of a two dimensional massless Schwinger model. It is further shown that the U(1) axial anomaly of QED in a strong magnetic field is closely related to the ``nonplanar'' axial anomaly of a conventional noncommutative QED.Comment: 18 pp, no figure. v2: The version accepted to be publidhed in PR

    Risk Factors in Cause and Course of Multiple Sclerosis

    Multiple sclerosis (MS) is a leading non-traumatic cause of disability in young adults. It is a chronic neurological disorder characterized primarily by central nervous system (CNS) inflammation, myelin loss, and axonal pathology, resulting in progressive neurological dysfunction. Initially, inflammation is transient and partial remyelination occurs. MS is presumed to be an autoimmune disorder arising from complex interactions of both environmental and genetic factors

    Red blood cell morphology and plasma proteins electrophoresis of the European pond terrapin Emys orbicularis

    The European pond terrapin(Emys orbicularis) is a turtle found in southern and central Europe, West Asia and North Africa. In this study, we used juvenile E. orbicularis (females of 4 - 5 years old) which was captured from the different area of the Mazandaran province in April 2006. Blood was collected from the dorsal sinus into EDTA-coated vacutainer tubes. Plasma proteins were quantified and diluted to different ratios. SDS-PAGE was able to resolve 17 bands at minimum concentration of 51.0 mg/wellwhich contain high and low band with molecular weight of 130.0- 132.0 and 20.0-23.0 kDa
