When interpreting data from more common commercial particle size analysis techniques, care must be taken in extrapolating particle number distributions from methods that do not inherently count particles.
This creates a particle with an inverted aspect ratio as compared with the more common rod-like particles.
STEM-EDS and XPS analyses reveal that bimetallic RuRe particles are more common than monometallic Ru or Re particles in the VC- and MWCNT-supported catalysts, and hexavalent rhenium species are more easily reduced to tetravalent rhenium during the HDO reactions in these catalysts, suggesting that Ru and Re in close proximity are required for the efficient hydrogenolysis of phenols.
"It's a very elusive decay," says Laurence Littenberg, a spokesman for the international group of 50 researchers, "because you can't detect the neutrinos," and the pi meson is easy to mistake for particles from more common events.
Elevated LDL levels are associated with increased CVD risk, and small, dense LDL particles, relatively more common in diabetes, have a high susceptibility to oxidation.
As the separate particles approached one another, the strands knitted themselves into the more common form of double-stranded DNA, holding the particles together.
Moreover, of the two mechanisms that govern the concentration of LDL in plasma, these studies and others [ 7– 9, 12] demonstrate that overproduction of LDL particles is a much more common cause of elevated LDL-cholesterol and -apoB than impaired clearance.
The more common types of ionizing radiation are characterized by particle or quantum energies measured in thousands or millions of electron volts (keV or MeV, respectively).
In the second decade, when more wear particles may have accumulated, osteolysis is more common and rates of femoral osteolysis from 32 70% have been described (Räber et al 2001, Iwase et al. 2002).
The niobium cavity, which is more efficient than the more common copper cavities, can be used to build a particle accelerator producing 10 megawatts of beam power, which in turn could convert thorium into nuclear fuel.
