in order to evaluation of the process of genetic improvement rate and duration of grain filling among wheat cultivars, the field experiments were conducted at the agricultural and natural resource research center of golestan province in the growing seasons of 2007-2008 and 2008-2009. the 16 cultivars were sown in a randomized complete blocks design with three replications. the results showed th...

Aluminum alloys are considered a lot in the automotive and aerospace industry because of their high strength to weight ratio. In this manuscript, the gas forming process of aluminum AA6063 tubes at high temperatures up to 500°C is investigated, through experimental and numerical tests. Therefore, an experimental setup is prepared and so, tube specimens are formed in a die with square cross sect...

Using a new MBE growth technique, we fabricate a two-dimensional electron system which is bent around an atomically sharp 90 corner. In the quantum Hall regime under tilted magnetic fields, we can measure equilibration between both coand counter-propagating edge channels of arbitrary filling factor ratio. We present here 4-point magnetotransport characterization of the corner junction with fill...

A process corner monitoring circuit (PCMC) is presented in this work. The circuit generates a signal, the logical value of which depends on the process corner only. The signal can be used in both digital and analog circuits for testing and compensation of process variations (PV). The presented circuit uses only metal-oxidesemiconductor (MOS) transistors, which allow increasing its detection acc...

The success of any nanoimprint process depends upon its ability to exactly reproduce the template pattern. Thus, complete filling of recessed features in the template is an important issue that is controlled by the dynamics of the flow through these sharp structures. At these small scales, capillary forces are large and must be included in the fluid flow model. The mechanism of interface advanc...
