A perfusion system was designed whereby the oral cavity of the rabbit under urethane anesthesia could be exposed to water in isolation from the remaining gastrointestinal system and the nasal cavity. Tritiated water was recovered from one external jugular vein within 40 s of the commencement of oral perfusion.

ABSORPTION OF WATER-SOLUBLE VITAMINS
British Medical Bulletin, 1967An account of the absorption of water-soluble vitamins must deal with the intestinal transport of a group of structurally unrelated compounds with widely different properties. The characteristics of absorption of several members of the group have not yet been adequately investigated. It is therefore difficult to make many valid generalizations.

Water vapor absorption in insects
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1983In common with other animals the principal examples of water transport in insects are to be found in processing food and in excretion. Some insects and other arthropods are able to absorb water vapor using preexisting buccal or rectal structures. This unique exploitation of atmospheric water depends on adequate areas for condensing water vapor and the

Absorption of water-soluble vitamins
Current Opinion in Gastroenterology, 2003Water-soluble vitamins are required as enzyme cofactors in a wide variety of metabolic reactions. Riboflavin, niacin, and vitamin C are essential in redox reactions; thiamine and biotin are involved in macronutrient metabolism; and folate, vitamin B12, pyridoxine, and riboflavin play important roles in the regulation of S-adenosylmethionine production ...

Ultrasonic Absorption in Water
The Journal of the Acoustical Society of America, 1941The coefficient of absorption (2αν−2) of ultrasonic waves was measured by a radiation pressure method at frequencies from 7 to 50 Mc. The average value is given for each frequency. These cluster closely around 43.1 × 10−17, and there is no indication of a drop in 2αν−2. Errors entering into absorption measurements are discussed.

We have measured the spectral absorption of water from 340-640 nm using a laser photothermal technique. Transmissive techniques have generally been used to measure the spectral absorption of water but such measurements require corrections for scattering.

AbstractThe rate of water absorption of U.S. and Japanese soybeans has been measured at 10° and 25°C. and at initial moisture levels ranging from 7.5 to 14.0%. The principal controlling factor in absorption of water is the seed coat. However the rate of water absorption of sound whole beans is also influenced by the initial moisture level in the beans;

[Water absorption by composite resins].
Archivio stomatologico, 1990A literature review about water absorption in dental composites has led to a number of hypotheses made for the variables affecting the experimental behaviour. It follows a discussion about the possible advantages and disadvantages of the fenomenon.

Atomic Absorption Spectrophotometry in Water Analysis
American Industrial Hygiene Association Journal, 1969Abstract The application of AAS to the analysis of major and certain trace elements in fresh and natural waters has been discussed. Sodium, potassium, calcium and magnesium were determined either directly or after dilution with deionized water. Pre-concentration of trace elements by simple evaporation was found to be satisfactory and compared favorably

Water Absorption of Elastomers
Rubber Chemistry and Technology, 1963Abstract This study considers high temperature (160° C) water absorption in the absence of oxygen. Examination of the freezing behavior of water-swollen butyl gum vulcanizates shows the water to be disposed as discrete droplets of the order of 3µ diameter, corresponding in this case with soluble residues based on zinc.
