influences of the wood fiber acetylation as well as the compatibilizer mapp on water absorption, thickness swelling and dimensional stability of acetylated wood/ polypropylene composites (wpcs) were the main concerns of this research. wood fibers were acetylated with acetic anhydride without using any catalyst to achieve weight percent gains (wpgs) of 4.5, 7.5 and 17.6%. the acetylated fibers w...

Problem of water vapor absorption continuum in atmospheric windows. Return of dimer hypothesis. Abstract Two alternative hypotheses try to explain the origin of the continuum. The present communication gives new argument in favor of the dimer hypothesis. This argument is based on the existence of the wide component of line in absorption spectrum of polyatomic molecules. The continuum of water v...

despite a highly beneficial role of water soluble arabinoxylans, the information about the effect of their addition on the properties of rye dough is lacking. the aim of this study was to check the influence of their modification methods and properties on water binding capacity of rye flour and suggest some possible explanations for the action of various fractions of arabinoxylans. three modifi...

Near-infrared absorption of water and water-benzene mixtures has been measured at temperatures and pressures in the range of subcritical and supercritical condition of water. The molar absorption intensity of the OH stretching overtone transition of neat water was obtained. It decreases linearly with increasing pressure in the region of gas and gaslike density. Enthalpy for dimerization has bee...

Degradation of underwater images is different from normal images. In underwater imaging light interact with water in two ways, scattering and absorption. The scattering and absorption together is called attenuation of light in water. This attenuation is wavelength dependent. Because of scattering and absorption, underwater images are affected by back scattering, forward scattering and absorptio...

The purpose of this study was to determine the locus of interaction of angiotensin peptides with the sympathetic nervous system leading to alterations in jejunal sodium and water transport. At low physiological doses, angiotensin II (AII) stimulates jejunal sodium and water absorption, while at high doses peptide inhibits absorption and/or stimulates secretion. Both the stimulation of jejunal t...

Measurements of the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) on ENVISAT have been used to derive global water vapour total column amounts over ocean and land. For this purpose, the Air Mass Corrected Differential Optical Absorption Spectroscopy (AMC-DOAS) approach, which has already been successfully used with GOME data, has been applied to SCIAMACHY’s n...

the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g...

Interrelationships between metabolism, NaCl transport, and water transport have been studied in an in vitro preparation of rat ileum. When glucose is present in the mucosal solution, Na and Cl both appear to be actively transported from mucosa to serosa while water absorption is passive and dependent on net solute transport. Removal of glucose from the mucosal solution or treatment with dinitro...
