The rate of absorption of water by roots of transpiring plants is in general closely dependent upon the rate of transpiration, and a change in the rate of transpiration is soon followed by a corresponding change in the rate of absorption (3). Since the rate of absorption lags behind and apparently is dependent on the rate of transpiration it is usually considered that under conditions such that...

Macroscopic structure of paper influences how paper behaves in many ways. In this research, the relationship between macroscopic paper structure and water absorption behavior was investigated. The structure of the handsheets made from commercial hardwood pulp was modified by varying basis weight, beating levels and wet press levels. The structural properties as well as the water absorption prop...

Infrared measurements have been used to profile or image biological tissue, including human skin. Usually, analysis of such measurements has assumed that infrared absorption is due to water and collagen. Such an assumption may be reasonable for soft tissue, but introduction of exogenous agents into skin or the measurement of tissue phantoms has raised the question of their infrared absorption s...

farinograph is the most frequently used equipment for empirical rheological measurements of dough. it’suseful to illustrate quality of flour, behavior of dough during mechanical handling and texturalcharacteristics of finished products. the percentage of water absorption and the development time of doughare the most important parameters of farinography for bakery industries during production. h...

We have developed a terahertz absorption spectrometer suitable for strongly absorbing liquids such as water, and have precisely measured the absorption spectrum of water between 0.3 and 3.72 THz (10-124 cm(-1)). We have also examined the absorption spectra of aqueous 50 mM potassium phosphate buffers at pH 3 and 8, and find that they do not differ significantly from pure distilled de-ionized wa...

Mechanism of the absorption of drugs from oil in water emulsions was studied in the rat large intestine. Synthesized esters of fatty acids and phthalic acid-0.1% Polysorbate 80 was chosen as the emulsion system, the oil/water volume ratio was varied from 0 to 1, and the absorption from emulsions of sulfapyridine, salicylamide, and of acetanilide was investigated using in situ recirculation and ...

Nectarivores face a constant challenge in terms of water balance, experiencing water loading or dehydration when switching between food plants or between feeding and fasting. To understand how whitebellied sunbirds and New Holland honeyeaters meet the challenges of varying preformed water load, we used the elimination of intramuscular-injected [(14)C]-l-glucose and (3)H2O to quantify intestinal...
