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 ...

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.

Study of Water Absorption Properties of Water Absorption Core Made of Pulp Mold
Journal of Korea Technical Association of The Pulp and Paper Industry, 2020The water absorption properties of the water absorption core made of pulp mold were investigated in this study. The pulp mold samples were modified using various natural non-wood fibers such as cotton linter, kapok, abaca, Tencel and through the high bulk-forming process with the low polarity solvent in order to find main factors for improving the ...

Absorption of sound in sea water
Ultrasonics, 1963Laboratory and field data on the absorption of sound in sea- water are reviewed in the light of modern theory, including effects of pressure, temperature and salinity. The effects of temperature and MgSO4 salt concentration appear to be compatible from one investigator to another.

Spin-dependent absorption of water molecules
Biophysical Chemistry, 2005The effects of spin state of water molecules on its absorption on lyophilized DNA, lysozyme and some inorganic sorbents were studied. It was shown that the absorption rates of ortho and para water from vapor differ noticeably. The para isomer binding with preparations is distinctly faster than that of the ortho isomer in all cases.

Intestinal absorption of water and electrolytes
Clinical Biochemistry, 19761. Recent advances in knowledge of intestinal physiology have provided some insight into disturbed mechanisms and their clinical effects; for example, diarrhoea can now be defined biochemically as excessive fluid and electrolyte loss due to their malabsorption or excessive secretion. 2.

One of the most intriguing aspects of water balance in land arthropods concerns the mechanisms by which water vapour is absorbed from unsaturated air. The process has been recognized for a long time, but an explanation in physiological terms is still lacking.

Optical absorption coefficients of water
Nature, 1979THE absorption spectrum of water in the visible region has been widely investigated1–9 because of the basic, technological and environmental importance of liquid water. Despite these efforts, there are significant disagreements between experimental results: discrepancies of factors of ∼2 in the absorption coefficients are not uncommon between various ...

The Botanical Review, 1945
This review is concerned primarily with the nature and origin of the forces bringing about movement of water from soil or other media surrounding roots into the conducting elements of the xylem, and with those internal and external factors which affect the rate of such movement.
