In this paper, a new paradigm for coherent microwave polarimetric remote sensing observation of man-made metallic targets at sea is presented and demonstrated over real synthetic aperture radar (SAR) data. It based on the different symmetry properties targets. The rationale relies physical principles instead standard image processing. Hence, simple very effective filter to observe by full-resolution dual-polarized SAR data developed. technique compared classic approach, namely cross-entropy...
Alberta oil sands are known to contain the world's largest reserves of bitumen. The rapid growth in their production could result a significant environmental impact. Fingerprinting bitumen and petroleum products from is essential order better understand chemical compositions sands, prepare for potential spills, address associated problems. This study presents an integrated quantitative characterization other related oils using gas chromatography-flame ionization detection (GC-FID)...
Perfluorinated compounds (PFCs) are emerging environmental pollutants. Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) the two primary PFC contaminants that widely found in water, particularly groundwater. This study compared adsorption behaviors of PFOS PFOA on several commercially available adsorbents water. The tested include granular activated carbon (GAC: Filtrasorb 400), powdered carbon, multi-walled nanotube (MCN), double-walled nanotube, anion-exchange resin (AER:...
Polycyclic aromatic hydrocarbons (PAHs) are compounds of concern because most these toxic, carcinogenic, or mutagenic and relatively persistent in the environment. Reliable quantitative information PAHs is important to evaluate acute chronic harmful effects on ecosystem. Crude oils refined petroleum products contain many highly abundant heterocyclic PAHs, particular alkylated homologues naphthalene, phenanthrene, dibenzothiophene, fluorene chrysene (APAH). The PAH usually occur significantly...

A number of acyl radicals, RĊ=O, have been generated in hexane or di -t-butyl peroxide as solvent at room temperature by 308 nm laser flash photolysis, and their spectroscopic kinetic properties examined time-resolved infrared spectroscopy. The C=O stretching frequencies for the RĊ=O radicals are found to be higher than those corresponding aldehydes, RCHO, between 108 128 cm-1, an effect attributed a bond order radicals. For some typical values vC =O are: CH3Ċ=O, 1864 cm-1; (CH3)3CĊ=O, 1848...
