We feel, for instance, that we understand entangled actin solutions although ignoring or coarse-graining the filaments' detailed molecular structure.
Monolayer cultures of transformed kidney cells showed strong staining of coarse, randomly-orientated cytoplasmic filaments, whilst fibroblasts cultured from normal rat kidney demonstrated an ordered array of fine, parallel filaments.
The uneven tan filaments are coarser, stronger and shorter than the normal cultivated silk and it is used in fabrics such as pongee and shantung.
Compared to modern mammals the filaments were quite coarse, with each individual strand much larger and thicker than the corresponding hairs of similarly sized mammals.
Coarse in appearance, with regular-branching filaments that have cross walls separating multinucleate segments, Cladophora grows in the form of a tuft or ball with filaments that may range up to 13 cm (5 inches) in length.
The chromatin filaments thicken and become coarse forming a dense chromatin mass which eventually further condenses to form a homogeneous chromatin mass (Oko and Clermont, 1999).
From each section, the filaments were gently separated out from coarse sediment particles as a tuft and split with one half or quarter going to immediate enumeration and the rest being preserved with ethanol.
Even silk, a fine natural-fiber filament, is coarser, a full denier or more, and a human hair might be 100 times as thick as a single microfiber filament.
Utilizing a coarse-grained model, a filament network is prescribed within a two-dimensional circular space through nodal connections.
At the coarsest section of cocoon filament from 200 to 300 meters, the denier increases.
