Bert Allard,Hans Borén,Anders Grimvalltion constraints to coordinate points, the geometric primitives point, line, incidence and equality are interpreted as fuzzy predicates of a first order language. An additional predicate for the “distinctness” of point like objects is also used. Fuzzy Logic [.] is discussed as a reasoning system for作者: 小卒 時間: 2025-3-22 02:41 作者: 我要沮喪 時間: 2025-3-22 04:57

Factors to be considered in the isolation and characterization of aquatic humic substances,sure filtration to remove suspended sediment, sorption of humic substances onto XAD-8 resin at pH 2, desorption of humic substances in base, fulvic/humic separation at pH 1, desalting on XAD-8 resin, hydrogen saturation on cation exchange resin, and freeze-drying.

Structural features of aquatic fulvic acids by analytical and preparative HPLC followed by spectrosrray UV-Vis, and fluorescence detectors were used to monitor the HPLC separation. Preparative FA fractions were subjected to .H and .C solid state NMR, FT-IR, and ESR. The preparative and analytical RP-HPLC separations have shown that the FA macromolecule consists of at least two polymeric fractions作者: Medicare 時間: 2025-3-25 12:18
Fluorescence spectroscopy as a means of distinguishing fulvic and humic acids from dissolved and seinvestigated by fluorescence spectroscopy in the emission, excitation and, partly, synchronous scan excitation modes.

Characterization of organic materials by means of electrofocusing,nds that localize mainly in the acid region of the pH gradient, whereas after some months of incubation a much more complex pattern of bands develops, characteristically, in the neutral region of the gradient.

Nature of humic substances of Mollisol and Luvisol in the Canadian Prairies,The amount of humic acid (HA) was higher in the Mollisol than in the Luvisol. The opposite trend was observed for fulvic acid (FA). There was no great difference in elemental composition of HAs between the Mollisol and Luvisol.

Characterization of organic materials by means of electrofocusing,hose of organic matter in the soil.
