In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...

introdouction: dentinal hypersensitivity (dh) is one of the most painful chronic problems reported in dental offices. various methods have been applied for the treatment of dh. however, majority of them are either ineffective or last for a short period of time. it has been reported that lasers, particularly neodymium- doped: yttrium aluminum garnet laser (nd: yag), can be helpful in the treatme...

This paper extends the Integrated Conditional Moment (ICM) test for the functional form of nonlinear regression models to tests for parametric conditional distributions. This test is formed on the basis of the integrated squared difference between the empirical characteristic function of the actual data and the characteristic function implied by the model. This test is consistent, and has nontr...

This paper identifies that academic staff need to be suitably prepared to deliver wholly online courses, and outlines the steps taken towards achieving this, at one Higher Education institution in the UK. E-learning, whether partially (blended) or wholly online, is not simply about the technology, but also requires an understanding of the pedagogical considerations, and the skills that are need...
