The effluent generated from a thermal power plant waste is a mixture of several chemicals and to identify the effect of these chemicals on soil, a case study on naturally contaminated sites at Al-Musayyib region, Hilla city in Iraq has been carried out. Soil and water samples were collected from the sites and analyzed to identify the pollutants and their effect on soil characteristics. Laborato...

Solidification and stabilization (S/S) by agents stabilizers is an effective way to treat heavy metal-contaminated sediments. Optimization of curing condition crucial minimize the consumption reagents on base S/S. In this work, synergistic effects cement stabilizer mechanical strength leaching toxicity contaminated sediments were investigated, S/S conditions optimized using response surface met...

As with the consolidation time, the cooling rate applied during the solidification stage of the composite processing cycle influences the total processing cycle time, as well as the mechanical performance. By controlling the solidification rate, changes in the matrix morphology and crystallinity can be achieved, and hence different mechanical properties may be obtained. Control of the solidific...

Microcasting Shape-Deposition-Manufacturing is an approach to Solid-Freeform-Fabrication (SFF) process which is a novel method for rapid automated manufacturing of near-net-shape multi-material parts with complex geometries. By this method, objects are made by sequentially depositing molten metal droplets on a substrate and shaping by a CNC tool, layer by layer. Important issues are concerned w...

In string theory, the brane world scenario, where the Standard Model gauge and matter fields live inside some branes while gravitons live in the bulk, can be a viable description of our universe. In this note we argue that the brane world actually is a likely description of nature. Our discussion includes a revisit of certain issues, namely, coupling unification, dilaton stabilization and super...

Solidification/stabilization technology is commonly used in the remediation of heavy-metal-contaminated sites, which reduces leaching capacity heavy metals, but total amount metals soil not reduced, there still a risk metal re-release and contamination groundwater, groundwater solidified/stabilized sites needs to be assessed. Through analysis system structure combined with integration method po...

This paper presents an eddy-current-based technique for imaging the solidification of molten metal inside a metal pipe. This technique is motivated by the fact that the ac (alternating current) impedance seen from a solenoid placed outside the pipe is dependent on the distribution of the solidification inside the pipe provided that the ac frequency is properly chosen and the overall thickness o...
