Paper media

This brings to mind another common problem. SOPs must be readily available in areas where GLP work is conducted. Protocols also must be accessible. Even when these documents exist only in electronic form, they must still be available, especially in the laboratory and study rooms. This means that computer systems that contain these documents must be available in the laboratory and study rooms and that all personnel who conduct work according to these SOPs must have access. The same is true for protocols and protocol changes. In cases where a merged system exists, i.e., both paper and electronic media are simultaneously in use, it is perfectly acceptable that only the electronic form is available in the laboratory areas while electronic or paper documents are available in offices. The only caveat is that a process must be in place to ensure the equivalency of the electronic and paper media. 

Is copyright protection enough to protect a knowledge base Are knowledge bases significantly different from paper media Until these questions are answered, vendors will be reluctant to sell knowledge bases. 

On top of the actual cost of running the hidden factory, there are some serious disadvantages of paper media, which up until recently have been accepted without question because there were no alternatives. 

Edge (i) Stacked discs (h) Helical wound ribbon < Paper media are capable of extremely fine filtering. Metallic media have high strength and rigidity. 

Several presenters at the Electronic Notebook Conference, held in January 2005 in Atlanta, discussed the viability of collecting laboratory data and information within a fully electronic environment, versus on the traditional paper medium. The consensus was that the case law has already been established. The basis of their arguments forces us not to look specifically for electronic notebooks being used in case law, but instead look for examples where electronic evidence has been submitted.

Indicator papers frequently aid in the identification of chemicals. Strong mineral acids are acid towards methyl violet or thymol blue papers, moderately strong acids react acid towards Congo paper, and very weak acids are acid towards htmus and azolitmin paper. Strong bases show an alkaline reaction with turmeric or tropeolin 0 paper, medium strong bases with phenol-phthalein, and very weak bases with litmus or azolitmin paper. These papers are not recommended for use in quantitative analysis. ...

To hydrolyse an ester of a phenol (e.g., phenyl acetate), proceed as above but cool the alkaline reaction mixture and treat it with carbon dioxide until saturated (sohd carbon dioxide may also be used). Whether a solid phenol separates or not, remove it by extraction with ether. Acidify the aqueous bicarbonate solution with dilute sulphuric acid and isolate the acid as detailed for the ester of an alcohol. An alternative method, which is not so time-consuming, may be employed. Cool the alkaline reaction mixture in ice water, and add dilute sulphuric acid with stirring until the solution is acidic to Congo red paper and the acid, if aromatic or otherwise insoluble in the medium, commences to separate as a faint but permanent precipitate. Now add 5 per cent, sodium carbonate solution with vigorous stirring until the solution is alkaline to litmus paper and the precipitate redissolves completely. Remove the phenol by extraction with ether. Acidify the residual aqueous solution and investigate the organic acid as above. 

A common surface cartridge is the pleated paper constmction type, which allows larger filtration areas to be packed iato a small space. Oil filters ia the automobile iadustry are of this type. The paper is impregnated, for strength, with epoxy or polyurethane resia. Any other medium ia sheet form, similar to cellulose paper, such as wool, polypropylene, or glass may be used.

Nitrocellulose based lacquers often contain short or medium oil alkyds to improve flexibiUty and adhesion. The most commonly used are short oil non drying alkyds. Amino resins or urethane resins with residual isocyanate functional groups may be added to cross-link the coating film for improved solvent and chemical resistance. The principal appHcations are furniture coatings, top lacquer for printed paper, and automotive refinishing primers. 

Capstan imagesetters, the third common technology, slowly advance the film or paper across a flat surface. A single laser beam is scaimed across the width of the medium by a rotating polygon or resonant mirror.
