We conclude that separation of chromosome arms is promoted by Rad21 cleavage and that cohesin-independent cohesive forces maintain cohesion at centromeres until anaphase.
Clay-rich soils resist erosion well because of strong cohesive forces between particles and the gluelike characteristics of humus.
Gravity, able to overcome the cohesive forces that hold soil particles together, can cause the entire soil profile to move downslope a phenomenon called mass movement.
The atoms or molecules of a liquid or solid are held together by cohesive forces, and these forces must be overcome in separating the atoms or molecules to form the vapour; the heat of vaporization is a direct measure of these cohesive forces.
In a solid or liquid, there is a dynamic balance between the cohesive forces holding the atoms or molecules together and the conditions created by temperature; higher temperatures imply greater distance between atoms.
As a physical example, consider the shapes of soap bubbles and raindrops, which are determined by the surface tension and cohesive forces tending to maintain the fixed volume while decreasing the area to a minimum.
Each case appears to be due to a set of different cohesive forces or a sequence of cohesive forces.
The cohesive forces between particles play a key role.
This is not the case for fundamental models where first principles rarely include cohesive forces.
If the bodies in contact can deform elastically and there are not cohesive forces between them, the contact is Hertzian.
For small cohesive forces, the amount of cleaning varies continuously with the applied stress, σ.
