No full textEffect of rare earth elements on growth and antioxidant metabolism in Lemna minor L
No full textLemna minor is frequently used in bioremediation processes to remove nutrients and contaminants from
waste water. In this work the response of L. minor to treatments with lanthanum nitrate and with a mix of several
light rare earth elements (REE) nitrates was investigated. Preliminary results indicate that L. minor shows an overall
good tolerance to the presence of REE in the media. Toxic effects were observed after prolonged exposition to high
concentration of REE. An increase in ascorbate and glutathione content as well as in ascorbate peroxidase, dehydroascorbate
reductase and ascorbate free radical (AFR) reductase activity was observed in treated plant

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
