A series of novel multithioether derivatives were synthesized by the combination of thiazoline and thiazine with dibromides and their structures were characterized by IR, H NMR, MS and elemental analysis. The synthesized derivatives were tested for antitumor activity.

Uncertainty in pressure sensitive paint (PSP) measurement is investigated from a standpoint of system modeling. A functional relation between the imaging system output and luminescent emission from PSP is obtained based on studies of radiative energy transports in PSP and photodetector response to luminescence. This relation provides insights into physical origins of various elemental error sou...

Ecological stoichiometry generally assumes that heterotrophs have a higher degree of elemental homeostasis than autotrophs. Differences between fixed consumer nutrient requirements and nutrients available in resources allow prediction of the intensity of nutrient recycling ensured by heterotrophs. Despite their fundamental role in detritus decomposition, extremely fewdata are currently availabl...

The disilylphosphido iron complexes (//5-C5R5)(CO)2Fe-P(SiMe3)2 ( lb -d ) result from the reaction o f the corresponding bromo compounds (//5-C5R5)(CO)2FeBr with LiP(SiM e,)2-2T H F. The complexes 2 b -d are cleanly converted into the diphosphenyl com ­ plexes (?75-C5R5)(CO)2Fe-P=P-M es* (2b-d) by treatment with equimolar amounts o f Mes*PCl2. The products l b d and 2 b -d have been characteriz...
