    Notizen: Abstract A (sulfonylbisphenoxy)-containing cyclotriphosphazene polymer system has been prepared by polycondensation of (phenoxy)chlorocyclotriphosphazene and 4,4′-sulfonylbisphenol. The syntheses by polycondensation using sodium salt of 4,4′-sulfonylbisphenol and by interfacial polycondensation were carried out for comparison. The characterization, thermal stability, and fire resistance of the synthesized polymers were studied. Thermogravimetric analysis showed that the polymers prepared were stable to above 400°C in nitrogen and exhibited high char contents at elevated temperature. The result indicated that the presence of a sulfonyl group was helpful for enhancing thermal stability and the presence of a phosphphazene ring was the cause of the high char residue at elevated temperature.

    Allotetraploid hybrids between citrus and seven related genera produced by somatic hybridization (1996)

    Schlagwort(e): Key words  Citrus cultivar improvement ; Germ plasm expansion ; Protoplast fusion
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract   We have developed an efficient protoplast-fusion method to produce somatic hybrid allopolyploid plants that combine Citrus with seven related genera, including four that are sexually incompatible. In this paper we report the creation of 18 new allotetraploid hybrids of Citrus, including ten among sexually incompatible related genera, that may have direct cultivar potential as improved citrus rootstocks. All hybrids were confirmed by cytological and RAPD analyses. If fertile, the attributes of these hybrids may be amenable to further genetic manipulation by breeding at the tetraploid level. Wide somatic hybridization of Citrus via protoplast fusion bypasses biological barriers to the natural allopolyploidization of Citrus, and creates new evolutionary opportunities that would be difficult or impossible to achieve by natural or conventional hybridization.

    A super element model for non-linear analysis of stiffened box structures (1993)

    Notizen: A numerical model for non-linear static and dynamic analysis of stiffened box structures is presented. The model is based on a new super element formulation which provides complete C1 continuity for both plate and beam elements. Geometric and material non-linearities are included and the temporal equations are solved by the implicit Newmark-β method with Newton-Raphson subiteration. The new formulation has been applied to the static, vibration and transient analysis of various structures such as flat plates, folded plates and rectangular boxes. Both isotropic and beam stiffened structures are considered and the results obtained are compared with other available solutions. It is observed that the new super element formulation can provide reasonable solutions to both linear and non-linear problems of stiffened box structures. The mathematical formulation of the model is presented in this paper, while the numerical verifications are given in the companion paper.1

    Notizen: Numerical investigations are carried out to verify the new super element model developed in Reference 1 for non-linear analysis of stiffened box structures. The results presented here are obtained from a variety of examples which are chosen to illustrate the accuracy and convergence of the model in various applications. Good agreement is obtained for most of the problems considered and the present formulation is found to be accurate and economical for preliminary engineering design.

    Modelling of concrete response to fluctuating load (1989)

    Notizen: An elastoplastic constitutive model for concrete subjected to cyclic loading conditions is presented. The model is an extension of a recently proposed constitutive concept.7 An initial active loading process is described, using the conventional framework of the rate independent theory of plasticity. An appropriate hardening/softening parameter is introduced which allows one to model the sensitivity of material characteristics to varying confining pressure, including a smooth transition from stable to unstable response. For stress histories that include stress reversals, the formulation invokes a set of neutral loading loci defining the conditions of the neutral state.8 The field of hardening moduli is specified through an appropriate interpolation rule which enables one to simulate adequately the effect of cyclic degradation of the material. The performance of the model is verified for some typical cyclic loading histories, and the results are compared with existing experimental data.

    Dynamic response of an elastic and viscoelastic full-space to a spherical source (1995)
    New York, NY [u.a.] : Wiley-Blackwell

    Notizen: The dynamic response due to a spherical source of radius a embedded in an elastic and viscoelastic full-space is investigated at a distance R from the source. Previous solutions to the elastic case are extended to incorporate realistic source pressure functions. The elastic solution is then cast in a scale independent form in order to generalize the application. The results show that the near-field of the spherical source may be defined by R/a 〈 5. For this region the particle velocity and displacement decrease as R-2, and the risetime decreases as R-1. However. in the far-field region (R/a 〉 5) the particle velocity and displacement decrease as R-1, and the risetime is independent of R. A non-constant Q model is developed to model viscoelastic attenuation and a complete analytical solution for wave propagation is obtained by cascading the separate mechanisms of geometric attenuation and viscoelastic attenuation. A comparison of our analytical model with the results of dynamic finite element modelling shows excellent agreement. This suggests that the method of cascading the separate transfer functions is a valid approach for wave propagation in viscoelastic media.

    Beschreibung: Author(s): M. B. Jungfleisch, W. Zhang, J. Sklenar, W. Jiang, J. E. Pearson, J. B. Ketterson, and A. Hoffmann The Rashba-Edelstein effect stems from the interaction between the electron's spin and its momentum induced by spin-orbit interaction at an interface or a surface. It was shown that the inverse Rashba-Edelstein effect can be used to convert a spin current into a charge current. Here, we demonstrate … [Phys. Rev. B 93, 224419] Published Mon Jun 20, 2016
