Chromatographic Determination of the Oxalate Ion in Patinas Covering Ancient Materials
No full textA procedure employing high performance ion chromatography (HPIC) for the determination of the oxalate species on patinas covering ancient works of art is reported. The problem coming from the low solubility of CaC2O4 is overcome by using a H2SO4 aqueous solution as dissolving agent and eluent in conjunction with an amperometric detector. A comparison with the results obtained by FT-IR spectroscopy on real samples is also reported. The small amount of the sample required and the low concentrations determinable indicate that the described method is an accurate microdestructive analytical procedure
Permanenze e trasformazioni nei centri storici. Una recente analisi della morfologia urbana della città di Padova
No full textIn a town, meant as a unitary complex in an organic sense, there can be recognized some homogeneous contexts with evident morphological pproperties. The analysis of such properties has been carried out in the streets, squares and other public areas and it allows, along with urban emergencies and historical development of minor building, to differentiate the elements opposite to the site values for which proper plans of intervention are required. Accordingly, in a study on the town of Padua, the architects Luciano Pontuale (University of Gena), Camillo Bianchi and Vasco Camporese (University of Padua), entrusted by the Town Council, verified in particular the environmental value of public areas and furnished the Councillorship of the Town-planning assisted by the Data Processing Centre with the opportunity to acquire a computerized records (in course of completion) to be able to indicate possible alterations for every single building for a better formal qualification of the context
Le costanti nell'analisi dell'architettura al variare degli interessi e delle prospettive nel campo del restauro
No full textLa disciplina del restauro architettonico vive al momento una delicata fase di riflessione: posta in discussione la fiducia illimitata nell'uso prevalente di materiali e tecnologie desunti dal fare del cantiere contemporaneo delle nuove edificazioni, l'attenzione è rivolta al tentativo di associare le necessità di conoscere i manufatti tradizionali con la volontà di intervenire su di essi adeguatamente attraverso l'uso di tecniche e materiali realmente compatibili ed affini al preesistente per comportamento e durabilità. Gli Autori descrivono gli strumenti e i metodi per un approccio efficacemente filologico al restauro di manufatti architettonici meritevoli di conservazione
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
