Panchromatic and multi-spectral images produced by the remote sensing satellites are fused together to provide a multi-spectral image with a high spatial resolution at the same time. The spectral quality of the fused images is very important because the quality of a large number of remote sensing products depends on it. Due to the importance of the spectral quality of the fused images, its eval...
the mode of coordination of8 manganese(fi), cobaltm, nickel(h), copper(ii), zinc(h), lead(ii) and cadmium(i1) to sodium ascorbate (nahasc) was investigated using ir, uv-visible, aas, elemental microanalyzer, conductivity, magnetic and 'm and i3c nmr spectroscopic studies, nanasc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl gro...
some n¬-acyl-n'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. the structures of synthesized compounds have been characterized by ir, 1hnmr spectral studies. the synthesized compounds 5(a-f) have been screened for antibacterial activity. the effect of the structure of the investigated compounds on the antibacterial ...
