    Numerical Simulation of Fluid-Structure Interaction of LNG Prestressed Storage Tank under Seismic Influence

    X. H. Du1, X. P. Shen1

    CMC-Computers, Materials & Continua, Vol.20, No.3, pp. 225-242, 2010, DOI:10.3970/cmc.2010.020.225

    Abstract Aim of this paper is to estimate the integrity of liquefied natural gas (LNG) prestressed storage tank under seismic influence. The coupled Eulerian-Lagrangian (CEL) analysis technique is used to simulate the fluid-structure interaction between LNG and the cylinder of LNG prestressed storage tank. The 3-D model of LNG has been dispersed by Eulerian mesh that is different from traditional analysis method which is called the added mass method. Meanwhile, both of the 3-D models of prestressed rebar and concrete structure are dispersed by Lagrangian mesh. Following conclusions are obtained: 1) Natural frequency of the whole… More >

    Storage lipids and proteins of Euterpe edulis seeds

    VÍCTOR PANZA1,2, DARIO PIGHIN3, VERÓNICA LÁINEZ2, RICARDO J. POLLERO4, SARA MALDONADO1,2,*

    BIOCELL, Vol.33, No.2, pp. 99-106, 2009, DOI:10.32604/biocell.2009.33.099

    Abstract Comparative studies on fatty acid and protein composition of the endosperm and embryo of palmito (Euterpe edulis Martius) were conducted using gas-liquid chromatography and sodium dodecyl sulfate–polyacrylamide gel electrophoresis. On a dry weight basis, the embryo contained extremely lower amounts of lipids and proteins than did the endosperm, which was associated with the scarce lipid and protein bodies previously reported in axis and cotyledon. The fatty acid composition also exhibited differences between both tissues: (I) the fatty acid diversity was greater in embryo than in endosperm; (II) embryo and endosperm contained predominantly linoleic, palmitic, oleic and More >

    ABSTRACT

    Structural Stability of Hydrogen Storage Materials

    M. Katagiri, H. Onodera1, H. Ogawa2, N. Nishikawa3

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.6, No.1, pp. 72-80, 2008, DOI:10.3970/icces.2008.006.072

    Abstract The microscopic mechanism of Hydrogen-Induced Amorphization (HIA) in C15 Laves phases of AB$_2$ compounds is studied. Experimentally, compounds in which the AA internuclear distance is reduced and BB internuclear distance expanded compared to pure crystals show Hydrogen-Induced Amorphization which suggests that the relative atomic size is the controlling factor. We investigate the role of the size effect by static and Molecular Dynamics methods using Lennard-Jones potentials. Our simulations show that in such a compound, the bulk modulus is remarkably reduced by hydrogenation compared to the isotropic tensile load, so that elastic instability is facilitated. This More >

    Effect of sugars on the association between cowpea vicilin (7S storage proteins) and fungal cells

    T.L. Rose*, V.M. Gomes*, M. Da Cunha**, K.V.S. Fernandes***, J. Xavier-Filho***

    BIOCELL, Vol.27, No.2, pp. 173-179, 2003, DOI:10.32604/biocell.2003.27.173

    Abstract Vicilins (7S storage proteins) found in various legume seeds have been previously shown to interfere with the germination of spores or conidia of phytopathogenic fungi and inhibit yeast growth and glucose stimulated acidification of the medium by yeast cells. In the present work vicilins from cowpea (Vigna unguiculata) seeds were added to the growth medium of Saccharomyces cerevisiae cells and Fusarium oxysporum conidia. Helix pomatia lectin, wheat germ agglutinin and Ulex europaeus lectin were used to identify differences in the binding of the vicilins to the surface of cells of S. cerevisiae and F. oxysporum treated with this protein. After the growth More >

    Atomic Modeling of Carbon-Based Nanostructures as a Tool for Developing New Materials and Technologies

    D.W. Brenner, O.A. Shenderova, D.A. Areshkin, J.D. Schall1, S.-J. V. Frankland2

    CMES-Computer Modeling in Engineering & Sciences, Vol.3, No.5, pp. 643-674, 2002, DOI:10.3970/cmes.2002.003.643

    Abstract The derivation of a bond-order potential energy function and a self-consistent tight-binding scheme is presented, followed by a survey of the application of these methods to calculating properties of carbon nanostructures. The modeling studies discussed include properties of functionalized and kinked carbon nanotubes, Raman shifts for hydrogen stored in nanotubes, nanotubes in a composite, properties of nanotubes in applied potential (electrical) fields, and structures and properties of nanocones, nanodiamond clusters and rods, and hybrid diamond-nanotube structures.
