Designed especially for capillary electrochromatography (CEC), silicate-entrapped columns are made by trapping particles of chromatographic packing material in a network of silica. Once entrapped, the capillary no longer requires frits. This renders a more homogeneous and stable packed bed. Accidental breakage of the fragile frits is not an issue with these robust columns. Columns packed with r...

A mainshock is usually accompanied by a group of ground motions. In many design codes, the effects seismic sequences have been neglected or underestimated. Aftershocks can increase structural damage even cause failure. The current study evaluated behavior rehabilitated and as-built reinforced concrete (RC) structure under real scaled mainshock-aftershocks using nonlinear analysis. Verification ...

Motivation: It has recently become possible to build reliable de novo models of proteins if a multiple sequence alignment (MSA) of at least 1000 homologous sequences can be built. Methods of global statistical network analysis can explain the observed correlations between columns in the MSA by a small set of directly coupled pairs of columns. Strong couplings are indicative of residue-residue c...

the simulation of distillation columns is an essential step in design, optimization, and rating. in this paper, a new procedure has been proposed for the initial estimation of column profiles based on modified kremser’s group method for simple and/or complex columns. the effect of this initialization algorithm on simulation procedure has been studied through two examples. the results show signi...

this paper deals with the solution of a column with balcony loads. it is intended to determine the expressions for deflections and bending moments of the sections of a column under the action of transmitted loads from a balcony loaded at its free end by a force «p» and rigidly connected to the column somewhere between its ends. the action of this load on the column is equivalent to that of the ...

in this paper a simple model of a three story building with inclined first-story columns has presented. the stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. the considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...
