Influence Diagrams ( I D S ) are a graphic formal ism able to provide a compact representation of decision problems. IDs are based on the axioms of probabi l i ty and decision theory, and they define a normat ive framework to model decision mak ing . Unfor tunate ly , IDs require a large amount of in fo rmat ion that is not always available to the decision maker. Th is paper in troduces a new c...

introduction: the aim of this in vitro study was to evaluate the dissolving efficacy of eucalyptol and orange oil solvents associated with passive ultrasonic activation (pua) in zinc oxide-eugenol (zoe) based and epoxy resin-based root canal sealers. methods and materials: seventy samples of each sealer were prepared and then randomized according to the solvent and the time of the ultrasonic ac...

Poly(vinylidene fluoride-trifluoethylene), P(VDF-TrFE), electrospun membranes were obtained from a mixture of dimethylformamide (DMF) and methylethylketone (MEK) solvents. The inclusion of MEK to the solvent system promotes a faster solvent evaporation allowing complete polymer crystallization during the jet travelling between the tip and the grounded collector. The main electrospinning process...

Eight male subjects were experimentally exposed to toluene, p-xylene, and a combination of toluene and p-xylene in order to study the influence of coexposure and exposure to different levels of each solvent on their uptake and elimination. The exposures were performed for four hours at exposure levels equivalent to or lower than the Swedish threshold limit value for toluene, 300 mg/m3 (3.2 mmol...

the equilibrium constant of adduct formation between some triorganotin chloride of the type r3sncl (r=c6h5, p-ch3c6h4, n-ch3)ch2)3, c6h5-ch2 and lewis bases cl¯, br¯, and i¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. the average equilibrium constant values for the systems studied shows the following acceptor trend of tin(iv) in the triorganotin chlorides: p-tolyl > ...
