The confinement property in helical toroidal plasmas is clarified. The analysis is performed by use of the one-dimensional transport equations with the effect of the radiative loss and the radial profile of the electric field. The analytical results in the edge region show the steep gradient in the electron temperature, which indicates the transport barrier formation. Because of the rapid incre...

We propose that in nanotube field effect transistors (FETs) with small effective dielectric thickness the vertical potential drop across the nanotube diameter at finite gate bias can lower or eliminate the Schottky barrier at the electrode. This effect is demonstrated in single-walled carbon nanotube FETs fabricated on top of ultra-high-κ dielectric constant SrTiO3/Si substrates. These FETs sho...

Molecular-level simulations are used to examine the suitability of boron-nitride single-walled nanotubes (SWNTs) as fluidflow conduits in the nano-valve applications based on a molecular-mono-layer functionalized silicon cantilever. The interaction between the constituent atoms in the nanotubes is modeled using the Universal Force Field inter-atomic potential. Key functional requirements (a lar...

the phenomenon of how tests influence teaching and learning is commonly described as “wash back”in language instruction. literature indicates that wash back effect is a complex concept that becomeseven more complicated under different interpretations of the wash back phenomenon in teaching andlearning. in the present study, some definitions of wash back and its two major types were introduced,a...

fasciolosis is a cosmopolitan parasitic disease with considerable economic and public health importance. fasciola hepaticais the major cause of fasciolosis in man and domestic animals. although remarkable research works have been done around the optimum temperature and time required for miracidial development, little is known aboutthe exact susceptibility of fasciola hepaticaeggs to high temper...

Objective(s):Osteoarthritis (OA) is globally one of the most common diseases from the middle age onwards. Cartilage is an avascular tissue therefore it cannot be repaired in the body. Conservative treatments have failed as a good remedy and cell therapy as a decisive cure is needed. One of the best and easily accessible cell sources for this purpose is adipose-derived stem cells which can be di...

in this paper, the effect of electric field on two-dimensional low reynolds air flow around an airfoil and variation of the forces acting on the airfoil is numerically investigated. the electric current and poisson’s equations are solved and the outcome is considered as a source term in the momentum equations. the energy equation is not considered due to its weak effect on the phenomena. the fi...
