    Thermodynamic studies of dilute aqueous solutions of cyclic ethers and simple carbohydrates (1972)

    Notizen: Abstract Apparent molal volumes and compressibilities are reported for dilute aqueous solutions of cyclic ethers, simple carbohydrates, and related polyhydroxy compounds. The results for carbohydrates are considered in the light of two theoretical descriptions of such systems, i.e., the semiideal solution approach of Stokes and Robinson, and the McMillan-Mayer theory ty[e of approach as employed by Kozak, Knight, and Kauzmann. It is concluded that neither model is satisfactory, and that for these solutions a specific hydration model, described in more detail in another paper, is more satisfactory.

    Conformation and hydration of sugars and related compounds in dilute aqueous solution (1973)
    Springer
    Journal of solution chemistry 2 (1973), S. 99-118 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Heats of solution ; heat capacity ; dipole moments ; static permittivity ; carbohydrates ; dielectric relaxation ; sugar conformation ; alcohols
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract The effect of hydroxyl substitution on the nature of the hydration of an alkane chain has been studied by calorimetric techniques. Static permittivities (ɛ0) of a range of monosaccharides and related compounds in aqueous solution have also been determined. The (ɛ0) data, suitably processed, have provided information about the solute dipole moments. In conjunction with earlier results from volumetric, compressibility, and relaxation studies, the specific hydration model is further developed and the relationships between solute molecular conformations and solute-water interactions are discussed.

    Ti:Sapphire-pumped femtosecond optical parametric oscillators based on KTiOPO4 and RTiOAsO4 (1995)
    Springer
    Applied physics 60 (1995), S. 437-442 
    Details
    ISSN: 1432-0649
    Schlagwort(e): 42.55 ; 42.65 ; 42.60
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract The design, configuration and operation of Ti:Sapphire-laser-pumped femtosecond Optical Parametric Oscillators (OPOs) using KTP and RTA are described. The results presented include configurations capable of producing transform-limited pulses shorter than 40 fs and operating with pump powers as low as 50 mW. Tunability within the 1–3 µn spectral region is demonstrated using pump-tuning alone.

    The effect of drought on levels of abscisic acid, cytokinins, gibberellins and ethylene in aeroponically-grown sunflower plants (1986)
    Springer
    Plant growth regulation 4 (1986), S. 139-151 
    Details
    ISSN: 1573-5087
    Schlagwort(e): Abscisic acid ; cytokinins ; drought ; ethylene ; gibberellins ; sunflower ; water stress ; aeroponics ; roots ; shoots

    Notizen: Abstract Abscisic acid (ABA), cytokinins and gibberellin-like substances (GAs) were extracted from the roots and shoots of 17-day-old sunflower seedlings which had been droughted or were unstressed. Plants were grown in an aeroponic chamber which allowed for good control over degree of water stress and easy access to roots. Following methanolic extraction of lyophilized material, cytokinins were separated from the acidic growth-regulators on a cellulose PO4 cationic exchange column. The cytokinins were analysed by paper chromatography and HPLC and the soybean hypocotyl section assay. Semipurified acidic regulators were chromatographed on SiO2 columns and HPLC and aliquots assayed with the dwarf rice cv. Tan-ginbozu bioassay for GAs. Fractions known to contain ABA were purified by sequential reverse-phase HPLC of the acid and then of the methyl ester forms followed by quantitation as Me-ABA on GLC-EC. ABA losses were measured by using an internal standard [3H]-ABA). Ethylene production was also monitored in stressed and unstressed seedlings. The effect of drought on GAs and ethylene was minimal. The ABA levels were markedly higher in droughted plants. Stressed roots had 32 times more ABA than controls. The levels of cytokinins in the shoots of droughted plants were about half those in unstressed shoots, and qualitative differences occurred in the roots. Under stress a large peak of activity was present similar to zeatin glucoside which was not present in the unstressed condition. The results are discussed in relation to drought-effects on metabolism.
