Highly active natural pandanus-extracted cellulose-supported poly(hydroxamic acid)–Cu(II) complex 4 was synthesized. The surface of pandanus cellulose was modified through graft copolymerization using purified methyl acrylate as a monomer. Then, copolymer methyl acrylate was converted into a bidentate chelating ligand poly(hydroxamic acid) via a Loosen rearrangement in the presence of an aqueous solution of hydroxylamine. Finally, copper species were incorporated into poly(hydroxamic acid) via the ...

Ion-imprinting polymers (IIPs) materials draw the great awareness because of the powerful selectivity to the desired metal ions. Thus, the IIPs were prepared by using metals such as Co, Cd and Pb ions with modified curcumin as a functional monomer used for a complexing agent, in addition, ethylene glycol dimethacrylate (EGDMA) and 2,2-azobisisobutyronitrile (AIBN) are crosslinking agent and free radical generator, respectively. Aqueous HCl was used to leach the metal ions from the imprinted polymer ...

Segmentation of MR brain scans has received an enormous amount of attention in the medical imaging community over the past several years. In this paper we propose a new and general segmentation algorithm involving 3D adaptive K-Means clustering in a multiresolution wavelet basis. The voxel image of the brain is segmented into five classes namely, cerebrospinal fluid, gray matter, white matter, bone and background (remaining pixels). The segmentation problem is formulated as a maximum a posteriori ( ...

Load management is now a widely practiced option among electric utilities in the United States. As the capital cost for power plant construction has skyrocketed, and the load growth has slowed, the utility industry has found inexpensive capacity through load management. Now, as the load growth is slowly picking up, and the incremental benefit from additional load management activities is diminishing, the capacity (MW) for bulk power purchase is getting more and more expensive. This situation has ...
