steady hydromagnetic couette flow of class-ii of a viscous, incompressible and electrically conducting fluid through a porous medium in a rotating system taking hall current into account is investigated. heat transfer characteristics of the fluid flow are considered taking viscous and joule dissipations into account. it is noticed that there exists flow separation at the moving plate in the sec...
Timothy Williamson’s Knowledge and its Limits is a treasure trove of philosophical riches. By reversing the usual explanatory order and putting “knowledge first” in epistemology (p. v) Williamson reconceives the relationships between knowledge, belief, justification and evidence. While there is much to be said about Williamson’s ambitious project, I will focus on his imaginative account of evid...

An effect of activation with nanosized particles Fe 3 O 4 on structural and magnetic properties zinc-tellurite glasses 20·ZnO-(80-x)·TeO 2 -x·Fe (x=0, 1, 3, 7), prepared melt-quenching method, have been investigated. Some functional the were experimentally investigated X-ray diffraction, Energy dispersive Raman spectroscopies, SQUID magnetometry. The values average crystallite sizes calculated ...
The Hall effect is a powerful tool for investigating carrier type and density. For single-band materials, the Hall coefficient is traditionally expressed simply by , where e is the charge of the carrier, and n is the concentration. However, it is well known that in the critical region near a quantum phase transition, as it was demonstrated for cuprates and heavy fermions, the Hall coefficient e...
It is shown that if q is a prime power then there are Williamson-type matrices of order (i) 1/2q2(q + 1) when q ≡ 1 (mod 4), (ii)1/4q2(q + 1) when q ≡ 3 (mod 4) and there are Williamson-type matrices of order l/4(q + 1). This gives Williamson-type matrices for the new orders 363, 1183, 1805, 2601, 3174, 5103. The construction can be combined with known results on orthogonal designs to give an H...
Calculation of Hall coefficient in semiclassical approach requires the first and the second derivatives of the energy bands at the Fermi level. We use the Maximally Localized Wannier Function technique to determine the required band derivatives and calculate the ordinary Hall conductivity and ordinary Hall coefficient in Al,Cu, Pd, Li, Au, Ag and Pb cubic metals.
Abstract Ball-milled nanocrystalline Mg powders catalyzed by TiO 2 powder, titanate nanotubes and carbon were subjected to intense plastic deformation equal-channel angular pressing. Microstructural characteristics of these nanocomposites have been investigated X-ray diffraction. parameters, such as the average crystallite size, dislocation density distance determined modified Williamson–Hall a...
In this paper we study the integer quantum Hall effect (IQHE) on the systems with different types of impurities in delta and gaussian forms. The Landau energy levels in the presence of impurity split in two different levels,the extended and localized levels, emerging then the Hall step. Finally, we add a specified form of a quantum dot potential to a system with impurity, and observed that incr...
