Rubber protein aggregation

We must rather look for a growth-like process, during which the individual constituents slowly aggregate to build a long chain, i.e. a gradual process of propagation similar to that by which the chain polymers occurring in nature, e.g. rubber, cellulose, proteins, chitin, etc. are produced. 

Particle contamination of a ready to administer injection or infusion solutions can result from cracking glass ampoules and from piercing rubber stoppers. Particles can also originate from not fully dissolved powders or aggregation of protein substances. In general drip chambers of the administration systems are equipped with 15 pm filters which ensure particle removal and allow a sufficient flow even when gravity infusion is performed. Filters with smaller pore... 

Instead, the viscosity dependsonshear stress and/or time. Non-Newtonian fluids areclas-sifled as being time-independent, time-dependent, and viscoelastic. They exhibit characteristics where the apparent viscosity either increases as the rate of shear increases, such as polymer melts, paper pulp, wall paper paste, printing inks, tomato pur, mustard, rubber solutions, protein concentrations, and are known as pseudoplastic, or decreases as the rate of shear increases. Examples of the latter are comparatively rare but include TtOj suspensions, comflour/sugar suspensions, cement aggregates, starch solutions, and certain honeys.
