We reported, for the first time, the piezoresistance behaviors of single p-type 6H-SiC nanowires. The results suggest that present p-type 6H-SiC nanowires could be an excellent candidate for the fabrication of robust and reliable stress sensors.

Most studies on mergers and acquisitions are not sample selective. This study directly examines the motives of horizontal mergers by utilizing a sample of acquiring firms based on same SIC codes. A three factor Arbitrage pricing model was utilized, with Tobin’s q ratio as a measure of market power, to study the performance of the firms involved in the mergers. The results indicate the acquisiti...

The majority of skill-upgrading in the United States in the 1980s and early 1990s was due to within industry shifts in skill-intensity. Traditional trade theory, represented by the HeckscherOhlin model, predicts that trade affects relative employment primarily by shifting resources across industries. For this reason, many economists have concluded that international trade has played a minor rol...

After explaining the basic operation of a SiC JFET plus silicon MOSFET cascode circuit, the dynamics of cascode switching will be discussed and the use of a QRR tester to evaluate the reverse-recovery characteristics of a cascode circuit will be explained. A comparison of the cascode’s reverse recovery with that of a SiC MOSFET reveals that the JFET cascode actually performs better than the SiC...

the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...

one of the most important issues in groundwater is its contamination by heavy metals. because of chemical stability and poor degradation of heavy metals and their ability to accumulate in living organism’s bodies, they can become toxic. for this, 15 water samples were collected from the groundwater resources of the oshnavieh plain in september 2015 ,with evenly distributed, and then were analyz...
