S+Au interactions at 200,4 GeV were observed using emulsion chambers, permitting measurement of pseudorapidities in the central region with precision --0.01 unit. Scaled-factorial-moment analyses are extended to bin sizes smaller than those accessible to other fixed-target experimental techniques. For a sample of 151 central collisions, moments are calculated using both "horizontal" and "vertical" analysis techniques. While the moments are found to rise (in a log-log plot) with decreasing pseudorapidity bin size 8rf, their slopes roll off to approximately zero for 8rj < 0.1.
Densities, F, and viscosities, η, of glycine, DL-R-alanine, DL-R-amino-n-butyric acid, and L-leucine in 1.0, 2.0, 4.0, and 6.0 mol‚kg -1 aqueous 1,2-propanadiol solutions have been determined at 298.15 K. The partial molar volumes, V 2 ∞ , obtained from densities have been used to calculate the corresponding volumes of transfer, ∆ t V ∞ , at infinite dilution from water to different concentrations of aqueous 1,2propanediol solutions for rationalizing various interations. The Jones-Dole equation has been fitted to the viscosity data to calculate B-coefficients. Results show that in the case of glycine and DL-R-alanine the ion-dipolar interactions are dominating while hydrophobic-hydrophobic and hydrophilic-hydrophobic interactions are also showing their predominant role in other cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
