    Notes: Polyethyleneglycol of molecular weight 6000 was treated with 4-phenoxy-3,5-dinitrobenzoyl chloride in warm toluene. The product of this reaction is a white crystalline solid containing 0.1-0.2 mmol of labile phenoxy groups per gram of polymer derivative. In aqueous buffers of pH 7, the phenoxydinitrobenzoyl polymer reacts rapidly with side-chain sulfhydryl groups of cysteine, but very slowly with other functional groups found in polypeptides, yielding peptide-polymer compounds in which the peptide and polymer are linked by a thiol-sensitive dinitrophenylene bridge. Both small synthetic peptides and the B-chain of bovine insulin thus linked to polyethylene glycol are soluble in water and in some organic solvents. An arginine-containing peptide bound to the polymer was hydrolyzed by trypsin at the arginyl bond, indicating that the linear polyethyleneglycol support does not restrict access of enzymes to bound peptides. Release of peptides from the polymer is rapidly accomplished by treatment with thiols at pH 7 in aqueous solutions.

    Notes: Relative response factors (molar sensitivities relative to dibutyl phthalate) for homologous series of n-alkanes (C12—C26), trimethylsilyl esters of C10—C20 fatty acids (FAs) and bistrimethylsilyl derivatives of C8—C16 ω-hydroxy fatty acids (HOF As) were determined by integration of total ion chromatograms obtained using a conventional gas chromatograph-mass spectrometer in the electron impact ionization mode. For the alkanes up to C22 and for the FA-TMS derivatives up to C18 (C21 including the TMS carbons), response factors increased linearly with total number of carbons (r2 〉 0.99). The slope of this correlation (response factor = 0.0775n - 0.338, where n is the total number of carbon atoms in each analyte) is essentially identical with those determined in earlier studies for smaller molecules not containing silicon. For the HOFA derivatives up to C14 (C20 including TMS carbons), the molar response factors also increased linearly with total number of carbons, but for reasons not yet apparent the regression line for these homologs was different (response factor = 0.0330n + 0.456; r2 〉 0.99). Response factors for higher homologs in all three series fell below the regression line for the lower homologs, the deviation increasing with increasing molecular mass and increasing GC retention time. In all three series the upper limit to the linear portion of the correlation corresponded to the homolog whose GC retention time was ca 15 min under the conditions used; a high injection port temperature was found to be the most critical factor in extending the linear range of the correlation.

    Notes: A fundamental procedure is proposed for the identification of liquefaction in saturated soils based on the instability in the material's microstructure. The disturbed state concept (DSC) provides a unified constitutive model for the characterization of entire stress-strain behaviour under cyclic loading, and the values of disturbance at threshold states in the deforming microstructure provides the basis for the identification of liquefaction. The procedure is verified with respect to laboratory behaviour of two sands, saturated Ottawa and Reid Bedford. A mathematical analysis of the DSC constitutive matrix is also performed. Procedures for the application of the DSC for simplified analysis and design, and in finite element procedures are presented. It is believed that the proposed model can provide a fundamental yet simplified procedure for liquefaction analysis, and as a result, it is considered to be an improvement over the available empirical and energy-based procedures. © 1998 John Wiley & Sons, Ltd.

    Description / Table of Contents: Die Röntgenstreuung von Amino-, Epoxy-, Alkyd- und Esterharzen wurde untersucht. Aus dem diffusen Halo wurde ein effektiver Abstand der Polymerketten berechnet. Mit Hilfe der von Boyer und Miller vorgeschlagenen empirischen Korrelationen wurde die Querschnittsfläche der Kettenmoleküle ermittelt, und daraus wurden die Zahl der Atome zwischen zwei Verknüpfungen, der Steifheitsparameter der Kette und die isotherme Kompressibilität abgeschätzt.
    Notes: The X-ray diffraction of amino, epoxy, alkyd, and ester gum resins was investigated. The diffraction halo was used to compute an effective distance value in the polymers. With the help of the empirical correlation graphs suggested by Boyer and Miller the cross-sectional area of the chain molecules was evaluated, and from that the number of chain atoms per entanglement, the stiffness parameters of the chain, and the isothermal compressibility were estimated.
