Mercury exhibits more cohesion than adhesion with glass Rain water flux from a canopy. Among the forces that govern drop formation: cohesion, surface tension, Van der Waals force, Plateau–Rayleigh instability. Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral ...
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another. (Cohesion refers to the tendency of similar or identical particles and surfaces to cling to one another.)
For example, they block the metastatic cancer cells' ability to extravasate and home to secondary sites. This has been successfully demonstrated in metastatic melanoma that hones to the lungs. In mice, when antibodies directed against CAMs in the lung endothelium were used as treatment there was a significant reduction in the number of ...
Some examples of cell junctions. In vertebrates, there are three major types of cell junction: [4] Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions); Gap junctions [5] (communicating junction)
Cohesion (computer science), a measure of how well the lines of source code within a module work together; Cohesion (geology), the part of shear strength that is independent of the normal effective stress in mass movements; Cohesion (linguistics), the linguistic elements that make a discourse semantically coherent
Sister chromatid cohesion is essential for the correct distribution of genetic information between daughter cells and the repair of damaged chromosomes. Defects in this process may lead to aneuploidy and cancer, especially when checkpoints fail to detect DNA damage or when incorrectly attached mitotic spindles do not function properly.
As such, mass flow is a subject of study in both fluid dynamics and biology. Examples of mass flow include blood circulation and transport of water in vascular plant tissues. Mass flow is not to be confused with diffusion which depends on concentration gradients within a medium rather than pressure gradients of the medium itself.
