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
Polarographic Investigation on Uranyl(VI) Complexes in Dimethylsulfoxide. Part IV. Ammonia and Polyamines
No full textComplex formation of uranyl(VI) ion with ammonia and some polyamines has been studied by the polarographic technique at 25 °C in 0.1 M TBAP-DMSO solutions. The polarographic data could be explained in terms of the formation of the following complexes: [UO2(L)n]2+ where L = NH3, en, dmen and n = 2, 3; L = tn, hexn and n = 1, 2; L = tmen and n = 3; L = trien and n = 2. The relative coordinating abilities of the ligands have been discussed on the basis of the calculated βOx/βRed values

No full textmonochloroacetic acid were detd. in 1.00 M NaClO4 at 25 °C. Comparison is given with literature data for the Th(IV)-acetate system. The thermodn. values for the two systems indicate a lower stability for the Th-monochloroacetate complexes as compared to the Th-acetate complexes. The lower ligand basicity results in both a weaker metal-ligand interaction and a more extensive hydration of the complexes forme
Polarographic Investigations on Uranyl(VI) Complexes in Dimethylsulfoxide. 1. Monocarboxylic Ligands.
No full textThe formation of acetate, glycolate, chloroacetate and β-chloropropionate complexes of uranium(VI) in dimethylsulfoxide has been investigated by the polarographic method. 0.1M tetrabutylammonium perchlorate was used as supporting electrolyte. The 3:1 acetate and the 1:1 glycolate complexes give distinct cathodic waves; the polarographic behaviour allows to evidentiate also the 1:1 and 2:1 acetate, the 1:1 chloroacetate and β-chloropropionate complex formation. The formed complexes are stronger in DMSO than in water and the more so the harder the ligand. The (a)-character of uranyl ion is more marked in DMSO than in aqueous media
