Note di archeometallurgia sui reperti di Frattesina
No full textIndagini archeometallurgiche sono state condotte sui numerosi reperti in lega di rame di Frattesina.
Oltre a chiarire le tecniche di fabbricazione e le leghe usate, esse hanno permesso di ricostruire le sequenze operative impiegate per produrre i manufatti metallici. Inoltre da Frattesina provengono due oggetti in ferro provengono, uno dei quali è una fibula ad arco di violino frammentaria
Enteral nutrition in maxillo-facial surgery.
No full textAuthors report their experience in enteral nutrition (E.N.) on maxillo-facial surgery. From 1987 to 1989, 24 patients were subjected to enteral alimentation in the Department of Maxillo-Facial Surgery of the 2nd School of Medicine of "Federico II" University of Naples (Italy). 50\% of patients suffered from head and neck tumours, and 50\% suffered from traumatic lesions. Before treatment, patients' nutritional conditions were evaluated by anamnesis, azotic balance, hydroelectrolytic balance, anthropometric, bioumoral, and immunologic parameters. Basal energy expenditure was calculated through Harris-Benedict formula. Patients were checked every week, and E.N. allowed a rapid and adequate caloric increase
Accuracy in the diagnosis of parotid tumours.
No full textParotid lesions are often not easily classified. Important information is gathered by conventional and instrumental investigation. But these data are often insufficient to make a correct diagnosis. The authors have compared these techniques. In particular, they have evaluated their accuracy in identification of site and histology. 60 patients with parotid tumours underwent the same instrumental diagnostic techniques (echography, sialography, computed tomography and fine needle aspiration biopsy). In regard to the identification of the site, the highest percentage was achieved by computed tomography (98\%). Echotomography has shown an accuracy of 83\%, and sialography 87\%. Fine needle aspiration biopsy has allowed the definition of the histiotype in 98\% of cases. Computed tomography, echotomography and sialography have not allowed the definition of histiotype in malignant tumours, but in the case of benign tumours computed tomography has permitted a diagnosis in 29 cases (57\% of benign tumours). Echotomography and sialography in 25 (49\%) and 26 cases (51\%), respectively

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
