Measurement of activity-coefficients at infinite dilution of chlorinated solvents in commercial polyethylene-glycol ethers
No full textAmong the suggested scrubbing liquids, alkylene glycol dialkyl ethers are especially suitable because of their favorable properties. Activity coefficients at infinite dilution are reported in the literature only for single absorption liquids, but generally in industrial applications stabilized mixtures of these substances are used. In this work two commercial products were considered: Genosorb 300 and Genosorb 1843, mixtures of polyethylene glycol dimethyl ethers and of polyethylene glycol dibutyl ethers, respectively. Gas-liquid chromatography was chosen for the es:perimental determination of the activity coefficients at infinite dilution, in the temperature range between 42 and 90 degrees C, of commonly used organic solvents, belonging in particular to the halocarbon class
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
