Alternatives: "a comparative study of" or "a similar study regarding".
"Transit has a huge amount to do with New York's showing," said Roy Kienitz, executive director of the Surface Transportation Policy Project, a research group that put out a parallel study on Monday estimating that New York City's congestion level was actually 68th in the nation, behind even Albany's.
The conditions of gel synthesis were optimized with respect to cross-linker loading and monomer concentration using the results of a parallel study on the synthesis of star polymers of DMAEMA.
In this paper, we carried out a parallel study on Nb- and Ta-doped TiO2 anatase films both theoretically by first principles calculation and experimentally by sputtering deposition and optical/electrical characterizations.
A parallel study on high strength concrete (HSC), that was carried out earlier, was described in a previous paper (International Journal of Impact Engineering, Elsevier Ltd. 2003; 28: 1001–1016).
We conducted a parallel study, on a subset of the genes in Ethiopian highlanders.
During the course of submitting this paper, a parallel study on KIR haplotypes was published where 72 haplotype structures were reported [ 45].
By systematic variation of the amount of zinc, the deposition time and by a parallel study of electrodeposition on aluminium or zinc sheets it could be established that the growth reactions in the electroless or electrodeposition processes are identical.
A parallel study of genetic variation on human chromosome 22 [ 36] suggested that humans harbour similar levels of indel variation: indels represented 22% of the total polymorphic events, which is somewhat more than the 18% reported earlier, but within the predicted range estimate of 16%to25%5% of all sequence polymorphisms in humans [ 10].
Currently, his research centers on a parallel study of antisemitism and Islamophobia from the mid-nineteenth century onwards.
A parallel study of the effects of PEEP on carbon dioxide kinetics in anesthetized patients [ 52] demonstrated less marked changes, presumably because the intact thorax in patients blunted the increase in FRC and VDana and the intact pleural pressure gradient limited the generation of high V̇A/ lung units.
Three scenarios were developed by reflecting on the findings of a parallel study focused on the difficulties doctors face in their communication with chronic pain patients [ 46].
