The spatial and temporal distributions of multiple reductively dechlorinating bacteria were simultaneously assessed in a one-dimensional sand column containing a tetrachloroethene (PCE) nonaqueous phase liquid (NAPL) source and associated plume zones. The column was uniformly inoculated with a PCE-to-ethene dechlorinating microbial consortium that contained Dehalococcoides spp., Dehalobacter sp...

this paper focuses on using the recently developed extended finite element model for buckling analysis of edge cracked columns under concentric axial load. the effect of crack depth and its location on the carrying capacity of columns is studied. the effect of different boundary conditions is also investigated. numerical examples are offered to show the efficiency and effectiveness of the propo...

Data of two or more state variables are recommended for porous media flow parameter estimation by inverse modeling. In this context, it is desirable to minimize efforts and cost when measuring these variables. A method to analyze the suitability of different sampling alternatives to identify the flow parameters from transient flow experiments by inverse modeling is proposed and tested in a larg...

In CFT construction, unlike the conventional method of RC it is not possible to visually confirm launch state concrete after dismantling formwork. Therefore, in guideline, quality ensured by establishing specifications and construction regulations. we considered confirming filling status long narrow wetting sensor monitoring system. As a result experiment, was confirmed that developed system ca...
