A hollow cylinder apparatus was used to study some engineering properties of hollow cylindrical sand specimens prepared using the wet-pluviation technique. The refined specimen preparation method displayed good repeatability. Wet pluviation produced inherently cross-anisotropic specimens, with the level of initial anisotropy reducing with decreasing initial void ratio. The variation in the init...

Pseudosasa amabilis (McClure) (Poales: Gramineae) is a typical bamboo species naturally distributed in large area of south China and famous for its culm strength. Although bamboos were found to share the same development rule, the detailed internode morphology of bamboo culm was actually not fully expressed. We explored internode morphology of P. amabilis using 11 different physical parameters ...

Hemocyanin of the snail helix pomatia was studied by small angle X-ray scattering in 0.15 M phosphate buffer pH 6. The outer portion of the scattering curve showed minima, which indicated that the hemocyanin molecule is composed of a large number of identical (or very similar) nearly spherical subunits. From the position of the minima the radius of gyration R u of the subunit was calculated to ...

This paper aims to develop semi-analytical results of the poromechanical fields in a hollow cylinder subjected an asymmetric loading condition. The poroelastic properties vary radial direction. heterogeneous is approximated by multilayer structure which each cylindrical layer assumed be homogeneous. analytical field are first established transformed Laplace space, and then ones time space obtai...

We determine the unsteady temperature field depending on radial coordinate and thermoelastic state caused in a two-layer hollow thermally sensitive cylinder both by this action of external force loads. The nonlinear boundary-value problem heat conduction with discontinuous coefficients is reduced integro-interpolation method to Cauchy for system ordinary differential equations, which solved num...
