Assorbimento, trasformazione e lisciviazione dell'urea in alcuni terreni toscani
No full textThe behaviour of urea in some representative soils of Tuscany was examined. The urea sorption was found to be directly proportional to organic matter content and C.E.C., and inversely to pH.
The values of the urea transformation rate were in agreement with the ones found by other Authors in similar conditions.
Notable amounts of the leaching losses were solely found in sandy soils when exposed to high precipitations
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
