    Notes: We report the predicted combining site structure of the monoclonal antibody fragment. NC10.14, which is specific for the superpotent sweetener, N-(p-cyanophenyl-N′-(diphenylmethyl)guanidine acetic acid, using computer-aided molecular modeling and experimental methods, such as fluorescence spectroscopy and circular dichroism. This is the first computer-aided modeling study on a λ-chain antibody fragment. We have also identified the amino acids that are involved in ligand binding. Aromatic residues. L:91(W), L:96(W), and H:100G(Y) are predicted to make van der Waals contacts with the p-cyanophenyl moiety of the ligand. Residue H:56(K) is predicted to provide a counterion for the acetic acid moiety, and H:50(E) provides the negatively charged potential for interaction with the positive guanidinium group. We also make a comparison of the binding site architecture of NC10.14 with that of a related monoclonal antibody fragment NC6.8. © 1996 John Wiley & Sons, Inc.

    Die Konstitution des Alkaloides Juliprosopin aus Prosopisjuliflora A. Dc. 176. Mitteilung über organische Naturstoffe175. Mitt. s. [1]. (1980)

    Notes: The Structure of the Alkaloid Juliprosopine from Prosopis juliflora A. Dc.A new alkaloid, juliprosopine, has been isolated from Prosopis juliflora A. Dc. (Leguminosae), for which structure 1 is proposed. The piperidine moiety could be elucidated on the basis of spectroscopic data (MS., 1H-NMR., 13C-NMR.) of juliprosopine and the derivatives 2-4. The central hexahydroindolizine part and its substitution pattern has been determined mainly on the bases of the Hofmann-degradation product 11, which yielded the hydrogenation products 13 and 14. By ozonolysis 11 was converted to 16 and 18. It is proposed that juliprosopine was built up in nature by two ‘monomeric’ Prosopis alkaloids and one dihydropyrrol unit.

    Crystalline character of native and chemically treated egyptian cottons. II. Computation of variance of x-ray line profile and paracrystalline lattice distortions (1972)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A variance range analysis of the x-ray line profiles for seven cottons (native, ureatreated, and mercerized) has been carried out to get two estimates of the crystallite size from (1) the slope and (2) the variance intercept. Assuming the crystallite length of cellulose to be the same in ramie and native cottons under ideal conditions of growth, the relative fluctuation of the repeat length along the b-axis has been calculated for all the samples. This degree of paracrystalline lattice distortions is negatively correlated with the fiber bundle strength at zero gauge and appears to be the same as the imperfections referred to in the weak link theories of fiber strength. While the orientation parameters are also well correlated with strength, the degree of crystallinity does not seem to have any influence. Wilson's rigorous mathematical treatment of the number-average particle size, in relation to the two estimates from the variance slope and intercept as well as the particle size distribution, has been successfully applied for the first time to cotton fibers leading to a clearer understanding of crystallite size-strength relationship.

    Acyclic diene metathesis (ADMET) depolymerization of functionalized furan-based polymers (1994)

    Notes: Acyclic dience metathesis (ADMET) depolymerization of functionalized furan-based polymers prepared via aqueous ring-opening polymerization of 7-oxanobornenes has been investigated. Results indicate that while very high molecular weight poly [exo-N-methyl-7-oxabicyclo [2.2.1] hept-2,5-diene-2,3-dicarboximide] can be depolymerized to oligomers with ease, poly [2,3-dicarbomethoxy-7-oxabicyclo [2.2.1] hept-2,5-diene] is more resistant to depolymerization under similar conditions. This difference may be due to differential interaction of the carbonyls in the side chains with the metal atom of the catalyst in the proposed metallacyclobutane intermediate. ADMET depolymerization of poly [2,3-bis (trifluoromethyl)-7-oxabicyclo [2.2.1] hept-2,5-diene] was feasible, however, the extent of depolymerization was decreased due to the use of a coordinating solvent (THF) used during the depolymerization process. © 1994 John Wiley & Sons, Inc.

    Radiation resistant amorphous-all aromatic polyarylene ether sulfones: Synthesis, characterization, and mechanical properties (1986)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Notes: The synthesis and characterization of amorphous, aromatic, polyaryl ethers has been investigated. Detailed synthesis procedures are provided. The main thrust of these activities was to synthesize polymers which could serve as castable amorphous matrix resins for carbonfiber composites and which would be highly resistant to radiation degradation. It was important that these polymers not contain any aliphatic groups in order to contrast their behavior with the commercially available Bisphenol-A polysulfones. The approach taken was to synthesize a series of statistical or random copolymers derived from hydroquinone and biphenol together with 4,4′-dichlorodiphenyl sulfone. In order to produce copolymers of high molecular weight, modified techniques were developed which utilized potassium carbonate as a weak base and N-methyl-2-pyrrolidone as the aprotic dipolar solvent. Detailed procedures are provided in this paper for the synthesis of high molecular weight copolymers of this type. In addition, stress-strain, dynamic mechanical properties and preliminary electron beam (e-beam) degradation studies are reported significantly. Improved mechanical property retention after e-beam exposure was observed with the all aromatic polyether sulfones.
