Section 5: Other Test Guidelines; Guidelines are numbered with three digit numbers, the section number being the first number. Sometimes guidelines are suffixed with a letter. Guidelines are under constant review, with guidelines being periodically updated, new guidelines being adopted, and guidelines being withdrawn.
With stability testing, pharmaceutical industry inspects the quality of drug substances and drug products as per the guidelines outlined by US Food and Drug Administration and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use to make sure that they retained the quality over the period of time.
Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [2] Natural fibers can also be matted into sheets to make paper or felt. [3 ...
Synthetic: rayon, cellulose acetate, triacetate, natural rubber, nylon, polyester, polyurethanes; Metal: gold, silver, copper alloys; Decisions about appropriate textile stabilization are most effective when the fibers are identified. The primary method of determining a fiber type is through polarized light microscopy.
Bast fiber from oak trees forms the oldest preserved woven fabrics in the world. It was unearthed at the archeological site at Çatalhöyük in Turkey and dates to 8000-9000 years ago.

A study commissioned by UPOV examined the socioeconomic benefits of plant variety protection, 10 years after the accession of Viet Nam to UPOV 91. [46] The study found that the productivity of 3 major staple crops increased during this period: Yield gains were 18% for rice, 30% for corn and 43% for sweet potato.
Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, facilitating the separation of the fibre from the stem. [1] It is used in the production of linen from flax stalks and coir from coconut husks.
