Aufnahme-fahigkeit, /. absorbability, absorptivity, absorbing power capacity. -ge-Bchwindigkeit, /. absorption rate, -kolbeu, m. absorption flask, -pipette,/, a pipet calibrated to take up a definite volume. Cf. Ausflusspipette. -vermogen, n. absorptive power. 

Osmotic laxative effects are also produced by the polyhydric alcohols, mannitol and sorbitol, which unlike glucose cannot be transported through the intestinal mucosa, as well as by the non-hydrolyzable disaccharide, lactubse. Fermentation of lactulose by colon bacteria results in acidification of bowel contents and microfloral damage. Lactulose is used in hepatic failure in order to prevent bacterial production of ammonia and its subsequent absorption (absorbable NH3 nonabsorbable NH4+), so as to forestall hepatic coma.

In another direction, words ending in -tion, such as absorption, reflection, radiation, transmission, and diffraction, are process terms. As such, they should not be used for the entity absorbed, radiated, or transmitted, nor for the corresponding measured values, such as absorptance, absorbance, reflectance, and transmittance. 

The limestone dual alkali technology consists of four distinct operations SO2 absorption, absorbent regeneration, waste solids dewatering, and raw materials storage and feed preparation. A typical process flow diagram is shown in Figure 1.

Finally we mention some patents which have been delivered since 1990 on applications of conductive polymers in the field of microwave absorption. Absorbers containing polyaniline have been patented [100 103]. Some types of polypyrrole based absorbers have also been patented [104-106]. 

The physical appearance of pure gum and its complexes were often found to exhibit colour therefore their optical absorption characteristics in the UV-VIS region were studied in order to investigate their optical absorption, absorbance region, and the photo-charge separation therein. The optical absorption in the UV-VIS region was measured for coloured complex of gum Arabica, and when and where it was important.

Absorptivity, absorbance index, absorption cor i-cient the proportionality constant e, in Beer s law for light absorption A = elc, where A is absorbance, / the length of the light path, and c the concentration. If concentration is expressed on a molar basis, e becomes the molar absorptivity, molar absorption coefficient or molar extinction coefficient, i.e. e = A/lc, where I is the length of the light path in cm, and c is the molar concentration.

As already described, superabsorbency criteria depend on the absorbent s properties, the absorption measurement method and use method, and the conditions under which it is used with other materials. Therefore in this section we will not define superabsorbency as the maximum absorption of water with respect to the weight of the absorbent. Rather, it will be defined as optimum water absorption based on the purpose of the application. Employing this definition, we will discuss the synthesis of superabsorbent polymers, measurement of water absorption, absorbency and its water absorption characteristics, change of the required properties for superabsorbency in the main areas of, health applications, other superabsorbency of industrial materials, and moisture absorption of general superabsorbent polymers. 

In turn, the absorptivity of (3) in the copolymer has been determined using the monomer itself as a model [16]. The amount of 3 in the copolymer is calculated after correction for low level acrylamide absorption. Absorbance vs. concentration plots for both 3 and 4 followed Beer s Law. 

Commercial hop extracts are analytically evaluated on the basis of the major alpha acids content as revealed by LC. This obviously excludes the iso-alpha acids, the minor alpha acids and the deoxy-alpha acids which are all present in an ethanol hop extract and which can all contribute to some extent to the beer bittering capacity of the extract. The total amount of these compounds, expressed as peak area in Fig.115 of the corresponding peaks 6,7,8,9,10,11,14,17,18,19, is 7.3 %. With specific absorptivities (absorbances for 1% solutions) at 270 nm of 295 for the iso-alpha acids, 200 for the alpha acids and 300 for the deoxy-alpha acids the total extract content for these peaks is 5.6 %. 

Fig.118 shows that the specific absorptivities (absorbance for 1% solutions) for the cis and trans isohumulones are indeed practically the same at 270 nm (293 and 296 respectively) but that they are markedly different at other wavelengths. In the context of this result, it should be mentioned that some of the published methods for iso-alpha acids analysis do measure the iso-alpha acids chromatographic peaks at decidedly different wavelength than 270 nm. Fig.118 is for the cis and trans isohumulones. We believe that the same situation applies to the cis and trans isocohumulones.
