Mercury was refluxed in countercurrent molecular stills in order to concentrate 204Hg. Two glass sti lls , with heater and cooler placed outside the distillation columns, and one still, consisting of a glass column heated externally and a stainless-steel cooler placed concentrically inside the column, were used . As compared with a lO-cell steel column described previously, these columns showed...

Abstract Composite sections are found to be a novel technique in modern day scenario of construction. This stands tall than the ordinary and conventional type constructions. Columns as structural element play vital role frame. research comments on behavior composite columns. The main objective this study is analyze steel-encased concrete columns experimentally under axial compression mode failu...

Objective. The article proposes a method for finite element analysis of pipe-concrete columns in physically nonlinear setting by reducing three-dimensional problem to twodimensional one based on the hypothesis plane sections. Method. equations theory plasticity concrete G.A. Geniev are used. technique was tested comparing solution with calculation LIRA-SAPR software package, as well experimenta...

In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...
