Advances in the adsorptive particulate flotation process
(2003-09-18)
The removal of contaminants from liquid effluents by the adsorptive particulate flotation (APF) process, including new adsorbents and flotation devices, are reported. Herein, contaminants are adsorbed (and/or absorbed) ...

Numerical study of inherent deformation produced in thick plates through bending by line heating
(2006-06)
In ship building, line-heating is widely employed as an effective method to form steel plate with complex 3-dimensional carved geometries. However the plate bending by line heating is strongly dependent on skills. To ...

Influential factors affecting inherent deformation during plate forming by line hating (Report 1) - the effect of plate size and edge effect
(2007-09)
The authors aim to propose an accurate and practical method to predict the deformation of actual plates of large size such as those used in shipbuilding. This method is to be used to improve the accuracy of an automatic ...
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
(2008-08)
As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ...
Effect of phase transformation onset temperature on residual stress in welded thin steel plates
(2008-12)
The effect of solid-state phase transformation at low temperature on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solidstate ...

de um material sorvente a partir de bentonitas brasileiras
modificadas quimicamente com o objetivo de aumentar sua
capacidade de sorção de metais pesados e seu valor
agregado. ...
Adsorption of Cu ions onto a 1.10 phenanthroline-grafted Brazilian bentonite
(2003-02-01)
The grafting, by chemical adsorption, of molecular 1.10-phenanthroline (OP) onto some Brazilian bentonite (montmorillonites) was studied to improve their adsorptive capacities to remove Cu ions from synthetic wastewater. ...
