More recent studies challenge this view and indicate that the role of an extensive sea ice cover may have been as important in promoting abrupt climate change as reorganisations of the North Atlantic Ocean [Gildor, H., Tziperman, E., 2003. Sea-ice switches and abrupt climate change.
Addition of native and surface-functionalized siliceous nanoparticles varying in hydrophobicity and inherent aggregation to a nanostructured block copolymer melt has little effect on the rheological properties at low nanoparticle concentrations, but promotes an abrupt increase in G′ and a corresponding decrease in tanδ (below unity) at high nanoparticle loading levels.
The process promoted stacking by abrupt depletion of ionic compounds in the sample zone (Fig. 2c).
Mr. Waitt, who founded Gateway in 1985 and resumed his former job of chief executive on Monday after the abrupt resignation of Jeffrey Weitzen, promoted Joseph Burke, above, who had been vice president for global business development to the chief financial post.
There are many reasons for deploring the money-mad practice, beloved of certain producers, of promoting wholly inexperienced film stars to abrupt centre-stage status in order to make a fast, dishonest buck in the West End.
The experience of an abrupt fall in light intensity promotes rapid turning ('well' condition), whereas runs are elongated by constant light stimulation or by a linear rise in light intensity ('mesa' and 'linear' landscapes).
The abrupt junction between germanium and silicon promotes the formation of misfit dislocations at the interface and threading dislocation that run across the whole germanium layer with an estimated density of about 109 cm−2.
Compared to previous acoustic wave velocity data on SiO2 and MgSiO3 glasses, Al2O3 appears to promote a lowering of the pressure at which the abrupt increase of dV S /dP is observed.
Abrupt dissociation of TRPC3 from NCX may promote arrhythmic events.
The abrupt topography of the island must also have promoted isolated settlements of the Spanish colonizers in historical times that, after mixing with the local aborigines, kept relatively segregated until recent times.
