Aginsky v n some new ideas for dating ballpoint inks
By Nato Locktongbam Central Forensic Science Laboratory, Directorate of Forensic Science Services, Ministry of Home Affairs, Government of India, Kolkata Dr. In order to address these challenges, an attempt was made to study the rate of diffusion of inks at different time intervals using hyperspectral imaging.
One hundred pens were randomly obtained from a variety of sources and their respective ink compositions were compared with standards.
Eighty-five of the inks were determined to be suitable for comparison utilizing optical examinations and thin-layer chromatography.
Readers are invited to submit articles for publication. Books printed in Latin America make up a significant part of the holdings of U. This means that a central record of microfilmed books must be kept so that libraries will not duplicate each other's work. (3B1.4) "Analysis of Ancient Paper and Ink," by Vilia Grosso. (3B2.2) "The Applications of the Polarizing Microscope in Ceramics," by Albert B. The polarizing light microscope was one of those old favorites. (3B2.2) "Einfahrungen eines Einzelkämpfers mit dem Jenaer Papierspaltverfahren," by Johannes Sievers. Background: Paper splitting, a European technique, is like lamination on the inside of the sheet instead of the outside: strong supports are glued with a water-soluble adhesive to both sides of a sheet of deteriorated paper; the supports are pulled apart, splitting the paper through its middle layer, to within an inch or two along the end (to help with alignment later on).
Prepared by ICCROM and published by the Getty Conservation Institute, 4503 Glencoe Ave., Marina Del Rey, CA 90292-6537 (310/822-2299). It is not a journal; it is not a newspaper; it must be a newsletter. They are often on groundwood paper, and most of them need microfilming almost as soon as they are received, because they deteriorate so fast. Aging results indicate that dew point rather than relative humidity is the best predictor of chemical stability in storage--the lower the dewpoint, the better. This champion of the PLM describes how it works, how to use it, and applications; he provides color photographs of typical fibers and crystals, a summary of the history of titanium white pigments, sources of supply and a bibliography. Despite the rapid technological advances that accompanied the First World War (which at that time, not knowing that there would be a second, they called "the recent war" or "the Great War"), the author says that it had often been easier and more satisfactory to use and develop old instruments along new lines. This is a lighthearted but professional discussion (all in German) of paper splitting using enzymes.
In the masthead it says, "Articles are selected for publication by the editors in consultation with subject experts. This is what makes bibliographic control important. A thin, strong paper is glued between the two sides of the sheet, using an adhesive not soluble in water, and the outside supports are then loosened and removed in a water bath.
