Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [8]
An ambiguous abbreviation that should be avoided. Some writers use it to mean lateral (transverse) chromatic aberration, TCA, while others use it to mean longitudinal (axial) chromatic aberration, LoCA. LCD: Liquid crystal display. A technology often used in the monitor screens of digital cameras, etc. [4] [11] LED: Light-emitting diode ...
The gas chromatography retention times and the mass spectrometry chromatogram are used to identify how the monosaccharides are linked to form the polysaccharides that make root mucilage. For monosaccharide analysis, which reveals the sugars that make root mucilage, scientists hydrolyse the root mucilage using acid, and put the samples directly ...
Heartfield used photomontage extensively in his innovative book dust jackets for the Berlin publishing house Malik-Verlag. [9] [10] He revolutionized the look of these book covers. Heartfield was the first to use photomontage to tell a “story” from the front cover of the book to the back cover.
The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce.The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, France, in 1826, but Niépce's process was not sensitive enough to be practical for that application: a camera ...
Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.
From January 2008 to December 2012, if you bought shares in companies when Aulana L. Peters joined the board, and sold them when she left, you would have a -8.1 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
