The direct current potential drop (DCPD) technique may be used in crack propagation tests to measure the growth rate (CGR). Potential probes attached specimen allow variation of length estimated. In this research, DCPD using one single probe was applied solid bar specimens (i.e., without any initial notch or crack) subjected low-cycle fatigue testing a simulated pressurized water reactor (PWR) ...

in this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. to improve the structural properties, sulfur was plasticized using dicyclopentadiene (dcpd) and methyl styrene (mst). plasticized sulfur composite was prepared by melt blending of plasticized sulfur and silica particles. the i...

Calcium phosphate cements (CPCs) with their biocompatibility, osteoconductivity and injectability plays an important role in bone defects treatment. Dual-setting cement is a promising approach to improve the physicochemical biological properties of CPCs which liquid phase contains dissolved monomers that polymerized during hardening process. In this study, series dual-setting were prepared by m...

Scheduling tasks in heterogeneous parallel and distributed computing environments continues to be a challenging problem. In this article, the authors investigate the Heterogeneous Earliest Finish Time (HEFT) algorithm, along with alternative scheduling policies for task prioritising phases and the Critical Path on a Processor (CPOP) for scheduling tasks on a heterogeneous multiprocessor system....

Abstract The formation, propagation, and detection of fatigue cracks are the key issues for life extension pressure pipelines metal welded joints. Especially in high-temperature high-pressure water environment nuclear power. Since interference measuring instruments noise would affect monitoring potential signals that characterize crack growth. Combined with relevant information various methods ...

?,?-Dienes are an important class of monomers due to their utility in the synthesis cyclopolyolefins and reactive polyolefin intermediates. In this contribution, terpolymerization two ?,?-dienes (i.e., 1,5-hexadiene 1,7-octadiene) with ethylene various cyclic olefins [i.e., norbornene (NB), 5-ethylidene-2-norbornene (ENB), dicyclopentadiene (DCPD)] catalyzed by a chelated imido vanadium complex...

Six Co-Rh/Fe3O4 catalysts with different cobalt loadings were prepared by the co-precipitation of RhCl3, Co(NO3)2, and Fe(NO3)3 using Na2CO3 as the precipitant. These catalysts were tested for dicyclopentadiene (DCPD) hydroformylation to monoformyltricyclodecenes (MFTD) and diformyltricyclodecanes (DFTD). The results showed that the MFTD formation rate increased with increasing cobalt loading, ...
