    Notes: Advantages of a hollow-fiber hemodialyzer have been well described. The goal of this program was to provide a working model of a noncellulosic hollow fiber artificial kidney with nonthrombogenic blood-contacting surfaces, low blood-priming volume and low pressure drop, a satisfactory rate of urea transport, and high rate of ultrafiltration of water. Also, the reliability and utility of these devices was to be demonstrated through clinical evaluation.

    Description / Table of Contents: Die Copolymerisation von Acrylnitril und Acrylaten wurde in Dimethylformamid bei hohem Acrylnitril/Acrylat-Verhältnis im Temperaturbereich von -50 bis +10°C durch Lithiumalkoxide initiiert. Die Bedingungen zur direkten Präparation von Spinnlösungen der Copolymere wurden erarbeitet. Das Lösungsspinnen dieser Copolymere durch Orientierungsfällung ergab Fasern mit hohen Festigkeitswerten.
    Notes: The copolymerization of acrylonitrile with acrylates has been initiated by lithium alkoxides in dimethylformamide at a high acrylonitrile/acrylate ratio over the temperature range from -50 to 10°C. The conditions for a direct preparation of spinning solutions of the copolymers were determined. The solution-spinning of these copolymers by orientational precipitation yielded fibres exhibiting high strength properties.

    BUCLAP2: A computer program for instability analysis of laminated long plates subjected to combined inplane loads (1973)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: This program description document describes the program structure and the design details of a CDC 6600 FORTRAN 4 digital computer program, BUCLAP2, which uses minimum energy principles to do an elastic stability analysis of curved and flat laminated rectangular long plates subjected to combined inplane normal and shear loads. Given the geometry, the material properties, and slected boundary conditions for the plate element, the program calculates the minimum buckling load for various wave lengths. The two parallel ends of the program calculates the minimum buckling load for various wave lengths. The two parallel ends of the long plate must be simply supported and arbitrary elastic boundary conditions may be imposed along either one or both external longitudinal sides. For guide to program use, see

    Storage hardening and “abnormal” groups in guayule rubberThis article was presented at the 27th IUPAC Congress, Helsinki, Finland, August 1979. (1981)

    Notes: The hardening process of natural (Hevea brasiliensis) rubber, that takes place when this rubber is stored in dry conditions over long periods of time, has been correlated with the presence of reactive “abnormal” groups directly grafted on the polymeric chain and in the serum of the latex. In the present work, natural Hevea (HR) and Guayule (Parthenium argentatum) rubber (GR) were stored under accelerated conditions and the changes in Mooney viscosity and molecular weight measured. The results showed that while HR undergoes hardening, GR keeps its Mooney viscosity constant, as does a constant viscosity (CV) Hevea rubber. These results are explained by the absence of functional “abnormal” groups that sustain the hardening reactions.

    Effect of fibronectin on the adhesion of an established cell line to a surface reactive biomaterial (1982)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 16 (1982), S. 195-207

    Notes: We have demonstrated that an established hamster cell line (NIL 8 M-2) will adhere to the bioceramic bioglass. The rate at which the NIL 8 M-2 cells assume a spread morphology on bioglass is density dependent and the morphology displayed by NIL 8 M-2 cells attached to bioglass is much more elongated than that displayed by NIL 8 M-2 cells attached to nonreactive glass. Precoating the bioglass with the plasma form of human fibronectin significantly reduces the density dependent nature of cell spreading. Coating the bioglass with fibronectin also reduces the time required for cell spreading and changes the morphology of the attached cells from an elongated to an extremely flattened shape. Our work raises the possibility that bone-implant adhesion might be improved by introducing molecules relevant to cell-substrate attachment into the biomaterial prior to implantation.

    Low energy electron loss studies of cuInSe2 surfaces (1982)
    Chichester [u.a.] : Wiley-Blackwell

    Topics: Physics
    Notes: The low energy loss spectra (LELS) of clean and oxygen contaminated (111) p-type CuInSe 2 single crystals are reported. Losses due to interband transitions and plasmon excitations are observed. By varying the primary electron energy (100-500 eV) both surface and bulk features of the conduction bands are probed. As oxygen is adsorbed on the surface of the CuInSe 2 (at room temperature), the In and Se atoms seem to associate with themselves and with oxygen, whereas the Cu atoms do not seem to play a direct role in the oxidation process. LELS Spectra are presented as a function of primary beam energy and oxygen absorption.

    Surface structure and NiO dispersion for NiO/γ-Al2O3 catalysts (1982)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 4 (1982), S. 234-239

    ISSN: 0142-2421

    Topics: Physics
    Notes: Chemisorption of CO at temperatures below 100°C has been used to evaluate the dispersion of NiO in a series of NiO/γ-Al2O3 catalysts. CO adsorption measurements were supplemented by i.r. spectroscopy to establish the CO/NiO stoichiometry. From monolayer coverage data derived from Freundlich's equation, the percentage of NiO dispersion and the average NiO crystallite size were calculated. The crystallite size of supported NiO was found to be practically constant for NiO loadings from 1 to 8 wt%, experimenting an abrupt increase for higher NiO contents. These results were consistent with additional information on the surface structure of the catalysts obtained by IR spectroscopy, X-ray diffraction, magnetic susceptibility, and reduction with H2.

Infrared and polarized Raman data are used in the force constant refinement routine. The assignments of the vibrational frequencies are discussed in terms of the potential energy distribution.
