The electromagnetic propagation through a homogeneous magnetized plasma slab is studied using the finite-difference timedomain method based on Z transforms. The reflection and transmission coefficients of the magnetized plasma layer for the right-hand circularly polarized wave are computed. The comparison of the numerical results of the Z transform and(More)
In an effort to design cyclic anhydride copolymers that have biodegradable characteristics and are derived from renewable resources, the copolymerization of itaconic anhydride and methacrylate-terminated poly-(L-lactic acid) (PLLA) was studied. Polymers with anhydride concentrations from 85 to 15 mol% have been synthesized successfully with retention of the(More)
Ultrasonic slurry sampling electrothermal atomic absorption spectrometry (USS-ETAAS) was been applied to the determination of lead in several fish samples. The influences of instrument operating conditions and slurry preparation on the signal were examined. Palladium and ammonium nitrate were used as the modifier to improve the signal. Since the sensitivity(More)
