Pauly&C.-CVM nella storia della vetraria veneziana d'epoca contemporanea: un caso di studio di storia aziendale
No full textL'articolo ricostruisce la nascita di due fra le maggiori aziende di produzione e commercio vetrario del secondo Ottocento e Novecento veneziano: la CVM (Compagnia Venezia Murano) e la Pauly&C., ricostruendone le vicende e in particolare la fusione nel primo dopoguerra a opera dell'imprenditore Gaetano Ceschina
LA STORIA
No full textNel capitolo del libro si prende in esame l'evoluzione della chirurgia vascolare con la successiva nascita delle tecniche mininvasive endovascolari. Si ripercorrono le tecnologie innovative messe a punto dai pionieri di queste tecniche ed in maniera particolare si descrive la nascita e l'evoluzione della tecnica di trattamento endovascolare degli aneurismi dell'aorta addominale messa a punto da J.C. Parodi

Novel 3D distinct element limit analysis model for the seismic vulnerability evaluation of historical masonry pagodas of major importance in China
No full textA new distinct element DEM limit analysis approach is presented and applied to the seismic vulnerability evaluation of an ancient masonry pagoda in China. The numerical model relies on the assemblage of infinitely resistant hexahedral elements and rigid plastic four-nodded interfaces, where all the internal dissipation lumps, constraining cracks to spread between adjoining elements. So, it is neither an upper bound nor a lower bound, but rather a DEM limit analysis. A masonry pagoda, Huqiu pagoda located in China, was selected as a case study to benchmark the model under the application of a seismic load. It is an octagonal masonry pagoda with a total of 7 floors and a height of 48.2m. The results show that the failure mechanisms found by limit analysis are basically vertical splitting with bending at the base. The results obtained by this research method are consistent with the actual behavior of masonry pagodas, which shows its suitability in direct applications by practitioners

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Isoamylase determination by isoelectric focusing in pancreatic disorders. A potential clinical aid
No full textIsoamylase analysis by isoelectric focusing was performed in the serum of 30 healthy volunteers, 65 patients with acute or chronic pancreatic diseases, nine with acute abdomen, four with macroamylasemia, and four with duodenal duplication. In controls, up to four fractions (2 salivary, 2 pancreatic) were found; the pancreatic fractions were as a mean 44.7% (SD 8.6) of total. In chronic pancreatitis, only patients with steatorrhea showed a significant reduction of pancreatic isoamylase (p less than 0.001). In all patients with acute pancreatitis or pseudocysts, an additional fraction (similar to the so-called P3 fraction) was resolved. Moreover, additional isoenzymes were found in all patients with severe acute pancreatitis or pseudocysts, and not in controls or patients with mild forms, acute abdomen or duodenal duplication. A similar pattern was shown in a stored control serum after 10 mo at -20 degrees C. These fractions disappeared after successful surgical drainage. No specific alteration was found in pancreatic cancer. Amylase fractionation by isoelectric focusing can be used to confirm an acute pancreatitis, and to monitor patients with pancreatic pseudocysts and collections after surgical drainage
