In either case, the polymersolvent system constitutes a semi—open thermodynamic system where the solvent molecules of much smaller size may enter or leave the space pervaded by the polyme

Entwurf eines Optimierungsmodells,ely pinching it into two parts (Figure 1), Cell cleavage by constriction is one of two general strategies of cytokinesis. In most plant cells a phragmoplast directs a restructuring process that begins inside the cell, resulting in an outward-growing wall. Each mechanism of cytokinesis is coordinated

Entwicklung eines Bezugsrahmens,or example the spherical cells of fertilized sea urchin eggs, can be thought of as the division of a sphere containing cytoplasm into two equal spheres with no change in cell volume . The process is driven by a contractile ring or furrow region near, or attached to, the cell membrane and localize

The process, whereby an egg starts dividing to give rise to an embryo, i.e. ‘cleavage’, can be triggered, in different species, by a variety of different treatments: fertilization by paternal sperm, artif

This mass deforms itself into more and more complex structures, and eventually develops into a new adult organism. What mechanical processes shape a multicellular organism?
