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
Generalized papular-purpuric eruption due to Solenopsis fugax bites
Full text linkA 59-year-old atopic man referred to for the onset of a diffused itching papular-purpuric eruption involving his trunk and legs but without systemic symptoms. History revealed that he started feeling itching after spending few hours in his basement. Direct examination of the environmental dust (www.edpa.it) showed high level of infestation of Solenopsis fugax, a small Myrmicinae ant. The skin eruption completely healed without scarring in 2 weeks. Specific disinfestation measures were performed and the patient did not comply of any recurrence during a 6-months follow-up

Full text linkWithin the framework of EUROfusion FP8 and FP9 research activities, an important work was carried out to optimize the DEMO Breeding Blanket (BB) layout. The blanket concept selected to be investigated in this work is the Water-Cooled Lead-Lithium (WCLL). The reference cell design for this activity is the WCLL2018.v0.6_B, associated with the component located at the equatorial plane of the Central Outboard Blanket (COB). During the last years, the Department of Astronautical, Electrical and Energy Engineering of Sapienza University of Rome, in collaboration with ENEA, has supported the optimization of the WCLL BB layout. One of the key design issues is evaluating the component thermal-hydraulic performances during operational and accidental conditions. Indeed, the aim of this work is to develop a RELAP5/Mod3.3 model of the COB equatorial cell suitable to investigate the component behavior during selected operational scenarios. To assess the system code modelling capabilities, due to the lack of experimental data, a benchmark activity was performed by comparing the RELAP5 outcomes with the results obtained with a Computational Fluid Dynamic (CFD) tool. The comparison demonstrates the capability of RELAP5 to properly simulate the cell thermal inertia, as well as to qualitatively reproduce the fluid and structural thermal fields
