The effectiveness factors of partially wetteb slab, cylindric shell, cubic and cylindric catalyst pellets in trickle-bed reactors are numerically computed at different wetting geometries for the generalized catalytic reaction A + B → P1, where A is a gaseous component and B is a nonvolatile liquid component.
A previously developed numerical model for nonlinear static and dynamic analysis of reinforced and prestressed concrete slabs and shells is presented.
The validity of four different grid beam configurations, as depicted in Fig. 13, was verified by comparing their responses with the so-called "exact" solution (the response obtained with a model that simulates the slab using layered shell elements with nonlinear material properties).
Contributions of various nozzle port angles and port widths and heights on the free surface fluctuation and the thickness of solidifying shell in slab mold were particularly investigated, based on which the structure of submerged entry nozzle was optimized.
The components in the form of cylinder for seed and seed stalk and slab for seed coat, shell and flesh were dried in thin layers at the air temperatures of 50, 60, 70 and 80 °C and relative humidity in the range of 10 25%.
The thickest layer contained a grid of concrete beams and was fastened to prefabricated concrete slabs, forming the hard shell of the island and acting as a protection against waves.
Herzog & de Meuron's Blavatnik School of Government in Oxford comes second, with its teetering stack of glass cylinders between wafer-thin concrete slabs, but whose glitzy shell encloses a grand gestural atrium of uncertain usefulness.
In the SAP2000 and ETABS programs, the R/C slabs are modeled as thick shell elements at the centerline of the slab thickness, and three cases are considered for modeling column-SW, namely (1) beam-beam, (2) beam-shell/wall, and (3) shell/wall-shell/wall; where beam and shell/wall refer to the type of elements used to model the columns and SWs, respectively.
The chapter elaborates the basic concepts related to a building's shell and frame, slab on grade, and interior construction.
We have used several transport codes to calculate dose and dose equivalent values as well as the particle spectra behind a slab or inside a spherical shell shielding in typical space radiation environments.
