Effect of pressure on the electronic structure of hcp Titanium
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
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
