It was a division of the Defence Science Laboratory (DSL) which is now called Laser Science & Technology Centre. The DRDO library which had its beginning in 1948 became a division of SIB in 1959. In 1967 SIB was reorganised with augmented activities and named Defence Scientific Information and Documentation Centre (DESIDOC).
A user–responsive collection of books, periodicals and electronic databases in the field of social sciences.. The Online Public Catalogue (OPAC) is for the use of library members/readers so that subject/author or keyword based searches can be made from the holdings of library books, Ph.D. theses, research reports, and journals.
Other liquid crystal materials change color when stretched or stressed. Thus, liquid crystal sheets are often used in industry to look for hot spots, map heat flow, measure stress distribution patterns, and so on. Liquid crystal in fluid form is used to detect electrically generated hot spots for failure analysis in the semiconductor industry. [85]
Cholesteric liquid crystals comprise both classes. Both small molecules and polymers can form cholesteric liquid crystals. In nature, examples include DNA, chitin, cellulose, and collagen, among others. [2] The local ordering in both nematic and ChLCs can be characterized according to the local nematic order parameter S.
Historically, most classes of technical documentation lacked universal conformity for format, content and structure. Standards are being developed to redress this through bodies such as the International Organization for Standardization(ISO), which has published standards relating to rules for preparation of user guides, manuals, product specifications, etc. for technical product documentation.
A common form is a pair of aromatic benzene rings, with a nonpolar moiety (pentyl, heptyl, octyl, or alkyl oxy group) on one end and polar (nitrile, halogen) on the other. Sometimes the benzene rings are separated with an acetylene group, ethylene, CH=N, CH=NO, N=N, N=NO, or ester group.
