No full textThe present study gives a useful way to optimize the operating (i.e. improving efficiency and saving energy) of a large wastewater treatment plant. The methodology was developed at the nitrogen removing activated sludge plant of “Roma-Est” (800,000 p.e.). Once design and operating data had been collected, a five-month experimentation was conducted to characterise the influent wastewater substrate fractions and to calculate the main kinetic parameters of the biomass. All data were used as parameters for a modified version of the ASM n.1 mathematical model, simulating the biological process flow, organic load and temperature variations as well as plant scheme modifications. Simulations showed the possibility of shutting down one of the three treatment lines and overloading the other two, with great operating improvement. Besides, neither the use of primary sedimentation, nor the aerated sludge internal recycle seem to be convenient.</jats:p
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
