severe plastic deformation (spd) methods were developed for producing of metals and alloys with ultrafine grained (ufg) microstructures having high strength. parallel tabular channel angular pressing (ptcap) as a noble severe plastic deformation (spd) method was used to produce ultrafine grained (ufg) and nanostructured cu-30%zn tubes. in this paper, the effect of ptcap process temperature on t...

When comparing rocketsonde and balloonsonde (radiosonde) temperature data, one notes systematic differences at levels of 25 km and above that increase with height. During the past 10 yr, systematic errors in the rocketsonde have been largely eliminated (at least for the region from 20 to 45 km), but little attention has been paid to the balloonsonde sensor. A study of temperature data for June ...

In India, most of the pavement is laid by bituminous road and the consumption of binder is high for pavement construction and also modified binders are used to satisfy any specific pavement requirement. Since the binders are visco-elastic material which is having the mechanical properties of binder transition from viscoelastic solid to visco-elastic fluid. In this paper, two different protocols...
