Removal of nitrogen and phosphorus is known to be somewhat problematic in vertical subsurface flow (VSSF)constructed wetlands. In this pilot-scale study, two planted (Typha latifolia L. [cattail]) VSSF-constructed wetlands A (with polypropylene pellets) and B (without polypropylene pellets) and one unplanted control C (without polypropylene pellets) were designed to test the contribution of pol...

In this work, the percentage of polyethylene (PE) and polypropylene (PP) blend is controlled at 50:50 to make composite by forming a co-continuous structure with hexagonal boron nitride (h-BN). The h-BN wrapped thermoplastic elastomer styrene-ethylene-propylene-styrene (SEPS). This approach enables localized distribution interface PE/PP SEPS phases, allowing construction heat conduction path in...

Semi-automatic wrapper generation tools aim to ease the task of building structured views over semi-structured web sources. But the wrapper generation techniques presented up to date are unable to properly deal with sources requiring complex navigational sequences for accessing data. In this paper, we present Wargo, a semi-automatic wrapper generation tool, which has been used by non-programmer...

In this work, post-consumer polypropylene and wood flour from Pinus elliottii were used to produce wood plastic composites. The effect of polypropylene grafted with itaconic acid used as a coupling agent on mechanical properties, thermal stability and morphology of the composites was investigated and compared with the composite developed with polypropylene grafted with maleic anhydride, commonl...

Image denoising as a pre-processing stage is a used to preserve details, edges and global contrast without blurring the corrupted image. Among state-of-the-art algorithms, block shrinkage denoising is an effective and compatible method to suppress additive white Gaussian noise (AWGN). Traditional NeighShrink algorithm can remove the Gaussian noise significantly, but loses the edge information i...

Polypropylene is extensively used for varied applications due to its low cost, low density, high thermal stability and resistance to corrosion. Enhanced mechanical properties of Polypropylene can be achieved by mixing it with clays to form nanocomposites which increases its utility. Polypropylene Nano composites are formed by mixing polypropylene with calcium carbonate nano particles. This resu...

The following paper reviews the possibilities of encapsulating existing legacy software for reuse in new distributed architectures. It suggests wrapping as an alternative strategy to reengineering and redevelopment. It then defines the levels of granularity at which software can be encapsulated before going on to describe how to construct a wrapper and how to adapt host programs for wrapping. S...

polypropylene / polystyrene blends containing montmorillonite (mmt) were prepared using a twin screw extruder followed by fiber spinning. the melt intercalation of pp and ps alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (mpp). the crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (pp/ps) nan...
