Artificial impregnated

These problems can be dealt with by usiag artificial test cloths impregnated with various approximations of natural soils such as vacuum cleaner dust, dirt from air conditioner filters, clays, carbon black, fatty acids, dirty motor oil, and artificial sebum, either alone or ia combination (37,94—98). The soils are appHed by sprayiag, immersion, or padding. If the soils are carefully appHed, reproducible results can be obtained. Soil test cloths can be of great help ia detergency studies, when used with an understanding of their limitations.

The terms embalming and mummification are often employed as synonyms to refer to the deliberate preservation of corpses so that they keep, as much as possible, their lifelike appearance. To embalm or mummify a dead body is to preserve it by artificial, chemical means. Dehydratation, the removal of water, for example, provides suitable conditions for the preservation of organic mater in general and of corpses in particular many ancient corpses have been mummified by dehydration. In some ancient societies, after the corpse was dry it was impregnated or filled with aromatic substances, usually known as balms, such as molten resin, pitch, or tar, preventing it from becoming unsightly. 

Chemical lures, based on feeding stimuli, are now on the market as odor-impregnated artificial bait. They are specific for certain predatoiy fish and are extremely effective (Schisler and Bergesen, 1996). Efforts to imderstand improving of feeding attractants and stimulants for economically soimd mariculture started early (Bardach and Villars, 1974). Another obvious application of fish odors is the use of waterborne male and female pheromones to improve spawning in fish in aquaculture. 

One decade has passed since the parallel artificial membrane permeation assay (PAM PA) was first introduced in 1998 [47]. Since then, PAM PA rapidly gained wide popularity in drug discovery [3, 48-51]. Today, PAMPA is the most widely used physicochemical membrane permeation model. The term PAMPA is nowusedas the general name for a plate-based (HTS enabled), biter-supported (filter immobilized) artificial membrane. Typically, phospholipids dissolved in an organic solvent are impregnated into the filter to construct a PAMPA membrane. 

A cumulative success of artificial ion-channel functions by simple molecules may disclose a wide gate for the design of ion channels and possible applications to ionics devices. Incorporation of these channels into bilayer lipid membrane systems may trigger the developments towards ionics devices. The conventional BLM system, however, is not very stable, one major drawback for the practical applications, and some stabilization methods, such as impregnating the material in micro-porous polycarbonate or polyester filters, are required. On the other hand,... 

It was Priestley who, in 1772, proposed to impregnate water direct with carbonic acid, and In 1774 prescriptions for the artificial production of Belters and I yrmont waters, founded on an accurate analysis of the same, were published by Bergmann.

Two main components were used in the model catalysts described in this paper. One component was a europium exchanged ammonium Y zeolite (EuNH-Y). The other component was an amorphous aluminosilicate containing about 75% Si 0 and 25% Al203 (AAA-alumina). All materials were artificially V-contaminated by impregnation with vanadyl naphthenate solutions in benzene. Tetraphenyl tin (in hot toluene) was the passivating agent used. It was added either before or after loading vanadium on the zeolite (EuNH-Y), on the gel or on a gel-zeolite mixture. 

Chemical lures impregnated with prey scent have been developed for different species of carnivorous fish. Lures for different game fish species are supposed to contain different chemicals, although usually not revealed on the labels of the products. The artificial lures are made of cellulose ether, a polyalkylene glycol, plasticizers, and other chemicals, and are impregnated with amino acids. 

The biomimetic membranes represent a special group of carrier membranes. They are artificial membranes based on biomembrane mimicking, i.e., imitation of the essential features bio membranes use for separation. Nitrocellulose filters impregnated with fatty acids, their esters, and other lipid-like substances may be used— in other words, an imitation of many nonspecific barrier properties of biomembranes. The transport of gas through these membranes will essentially be according to facilitated transport (see Section 4.2). Biomimetic membranes for CO2 capture will transport the gas as HCO3. Development of these materials may be expected for selected applications.
