A transient increase in the density of medium and large size intramembrane particles – and a corresponding decrease of small particles – occurred in the plasma membrane of C6BU-1 cellstimulateded for ACh release.
Total density, and density of medium- and large-sized individuals of the three predatory fishes were generally greater at the protected than at the fished breakwaters, whereas no differences were detected in the density of small-sized individuals.
Here, t is the time, x k is a coordinate (k=1,2,3), u i is a component of a displacement vector (i=1,2,3), and ρ is the density of medium.
where g is gravity acceleration, η is viscosity of medium, ϱ is density of medium, ϱ p is density of aggregating particles, d i is diameter of particle i.
"And of course the high-speed train, Shinkansen bullet train in Japan - instead of having a rounded front, it has something that looks like a beak of a kingfisher, a bird that goes from air to water, one density of medium to another," she adds.
This site was chosen because of the high density of medium spiny neurons at this level [37].
