Cells that adhered to 625 µm fibronectin islands adopted a round, unspread cell shape, while the cells on the larger fibronectin patterns were able to spread out to a surface area of 10000 µm (Fig. 5A).
However, under certain conditions, in particular, when exponential decay of the replicators is included into the model and/or spatial structures is incorporated, e.g. by allowing the replicators to spread on a surface, selection appears to be possible even under parabolic growth [ 15, 16, 18, 19].
The physical properties of mucus include spinability, which describes its thread-forming capacity and its internal cohesive force; adhesivity, its ability to bind a solid surface; and wetability, its ability to spread on a surface.
The virus can also spread to surfaces, such as a keyboard, and be transmitted to other individuals if they touch the contaminated surface and then touch their eyes, Schaffner said.
Pour your mixture into the lined tray and gently spread to level the surface.
Once the liquid tip touches the surface, it spreads to a contact face of diameter, wc, and subsequently collapses (retracts) to a sessile droplet on the tip of diameter woa and height hsa, with a residue droplet on the surface of diameter wr and height hr (refer to Figure 1C).
Mutation measurements are complicated by a process called 'field cancerisation', by which carcinogen exposure of a larger field of cells (e.g. oral or bronchial epithelium) leads to groups of related, but histologically normal, cells that spread to cover a large epithelial surface (Slaughter et al, 1953).
Ten μl aliquots of the organisms were inoculated onto bench top surfaces and spread to cover a 1 cm2 area.
The blastomeres divide and spread to eventually cover the surface of the egg, forming a blastoderm.
It will be more energetically favorable for an air bubble to spread on a glass surface than the hydrophilic retinal surface.
