Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
A fabric modifier or fabric treatment sheet can replace the fabric softening agent. Fabric modifier is made up of a selection of the group that consists of anti-creasing agents, anti-soil agents, anti-static agents, bacteriostatic agents, brightening agents, bodying agents, dyes, odor masking agents, fragrances, fiber emollients, finishing ...
In many cells these pits and complexes begin to concentrate in one area of a cell. Cytochemically, this appears as patches of label on the cell surface (patching). Eventually, the patches coalesce to form a cap at one pole of the cell (capping). Not all cells form caps, but most do form patches.
A mordant or dye fixative is a substance used to set (i.e., bind) dyes on fabrics. It does this by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). [1] It may be used for dyeing fabrics or for intensifying stains in cell or tissue preparations.
Capping may refer to: the creation of five-prime (5') caps in a cell nucleus Capping enzyme; Cap (sport), making an appearance in a game at international level; Ambulance chasing, the practice of lawyers seeking clients at a disaster site; Jakugo, or capping phrase, a response to a Zen kōan; Capping stunt, a New Zealand university student prank
Polydimethylsiloxane (PDMS) is a typical release agent. A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [1]
The "front" of a piece of fabric having a distinct front and back; same as right side. facing A facing is fabric used to finish the raw edges of a garment such as at neckline and armhole. Shaped facings are cut to match the edge they will face, and bias facings are strips of fabric cut on the bias or cross-grain and shaped to fit edge.
One of the earliest agent-based models in concept was Thomas Schelling's segregation model, [6] which was discussed in his paper "Dynamic Models of Segregation" in 1971. . Though Schelling originally used coins and graph paper rather than computers, his models embodied the basic concept of agent-based models as autonomous agents interacting in a shared environment with an observed aggregate ...
