this study focuses on tracing the clearly defined elements of magic realism in toni morrison’s song of solomon as an illustrious african american example of the mode. magic realism is a fictional technique that combines fantasy with raw physical reality in a search for truth beyond that available from the surface of everyday life. toni morrison, as a distinguished african-american practitioner ...

to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...

A novel element with arbitrary domain shape by using decoupled scaled boundary finite element (DSBFEM) is proposed for eigenvalue analysis of 2D vibrating rods with different boundary conditions. Within the proposed element scheme, the mode shapes of vibrating rods with variable boundary conditions are modelled and results are plotted. All possible conditions for the rods ends are incorporated ...

Recent measurements of a 2D electron gas subjected to microwave radiation reveal a magnetoresistance with an oscillatory dependence on the ratio of radiation frequency to cyclotron frequency. We perform a diagrammatic calculation and find radiation-induced resistivity oscillations with the correct period and phase. Results are explained via a simple picture of current induced by photoexcited di...

The logarithmic temperature dependence of resistivity, commonly observed in disordered films, has generally been interpreted as evidence for electron weak localization, with its slope indicative of the inelastic scattering mechanism. In this work, we show that the two-dimensional ~2D! quantum percolation ~QP! model, pertaining to disordered metallic films, predicts a sample-size-dependent lnL c...

9.4.1. Hall effect † Consider electrons moving in a 2D plane (the system is known as a 2D electron gas or 2DEG). If we apply an in-plane electric field E, we will get some electric current j. Typically, E  J . Let’s assume they are in the x direction Ex and jx. The resistivity is rxx = Ex  jx † Apply a B field perpendicular to the 2D plane. Lorentz force leads to charge accumulation for the ...

Submitted for the MAR11 Meeting of The American Physical Society Enhancement of Kondo effect through Rashba spin-orbit interactions1 NANCY SANDLER, MEHDI ZAREA, SERGIO ULLOA, Ohio University — The role of Rashba spin-orbit (RSO) interactions on the Kondo regime has been a topic of debate since resistivity measurements on Pt doped Cu:Mn compounds were interpreted as evidence for suppression of t...
