Thyroid hormone and retinoic acid increase Insulin-like Growth Factor-Binding Protein-4 (IGFBP-4) mRNA expression in prepubertal pig Sertoli cells

No full textThe kinetics of H redn. of Norwegian ilmenite ore powder was investigated at 927-1280 K. The activation energy of a surface chem. reaction was 69.6 kJ/mol as calcd. from wt. loss-time measurements according to the shrinking-unreacted core model. Optical microscopy of synthetically prepd. FeTiO3 pellets at redn. degrees of 25 and 35% showed the interface between the reacted and unreacted zones. An electron probe qual. anal. of the reduced specimens indicated a segregated Fe phase present as spheroidal nodules and TiO2 phase present in vein-like arrangements
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
