    Terra, legno e materiali deperibili nell’architettura antica

    No full text
    Il Convegno internazionale promosso dal Dipartimento dei Beni Culturali dell’Università di Padova ha approfondito il tema dell’uso dei materiali deperibili (terra, legno ed altri elementi vegetali) nell’architettura antica, con particolare riferimento agli edifici del mondo greco, magnogreco, fenicio-punico, etrusco e romano. L’idea di dedicare un convegno a questa tematica nota dalla consapevolezza che l’ampio panorama di studi sull’architettura antica ha rivolto finora un modesto interesse all’impiego di materiali deperibili a scopo edilizio, sia a causa dell’ampia diffusione negli edifici antichi di altre tipologie di materiali da costruzione, quali in primis la pietra e il laterizio, sia per il minor livello di conservazione di strutture in terra cruda e/o legno, sia infine per la maggiore difficoltà di riconoscimento e di analisi di tali strutture in fase di scavo. Gli Atti del Convegno raccolgono nuovi dati sulla diffusione delle tecniche costruttive in materiali deperibili, col fine ultimo di definire un quadro aggiornato sull’impiego di legno e terra in epoca antica in strutture ed edifici delle regioni del Mediterraneo e dell’Europa continentale, tra la Preistoria e la tarda antichità

    Abstract The aim of the study was to estimate the frequency of pneumonia and to determine the risk factors for this complication in poststroke patients with oropharyngeal dysphagia (OD). We prospectively followed up 67 patients (mean age 72.9+/-12.2 years) in the first 6 months after stroke, during which time we recorded gender, stroke side, type of lesion, diabetes, history of chronic obstructive pulmonary disease (COPD), smoking, level of consciousness, functional outcome, dietary history, occurrence of chest infection, and death. Degree of OD and presence/absence of reflex cough was assessed by Fiberoptic Endoscopic Evaluation of Swallowing. Sixty patients showed complete recovery of prestroke swallowing; 9 (13.4% IC 95%=5-20%) developed pneumonia, two of whom died. The first episode of pneumonia occurred in all nine patients within the first month after stroke onset. The pneumonia was associated with absence of reflex cough after swallow, COPD, and severe impairment of consciousness and poor functional outcome

    Con questo studio ci siamo proposti di valutare in un campione di soggetti disfagici in esiti di primo ictus cerebrale per un periodo di 3 mesi i seguenti aspetti: a) l’incidenza di infezioni polmonari, b) l’epoca di comparsa dell’infezione rispetto all’evento acuto, c) i segni clinici maggiormente predittivi di aspirazione e di complicanze polmonari, d) tempi di recupero dell’autonomia deglutitoria

    Dysphagia in post-carotid endarterectomy: a prospective study

    Dysphagia can be a debilitating complication in carotid endarterectomy. This study describes our experience in the management of this complication. We prospectively assembled an inception cohort of 19 consecutive, hospital-referred patients with dysphagia post-carotid endarterectomy. We performed swallowing evaluation in all the recruited patients both at the bedside and by fiberoptic endoscopic evaluation of swallowing (FEES) 5 days and 3 months after the operation, using standardized methods and diagnostic criteria. The degree of dysphagia was scored using the Penetration-Aspiration Scale (PAS). All patients were undergoing early rehabilitation treatment and were followed up prospectively for 3 months, during which time recovery of swallowing function and any occurrence of pneumonia were recorded. At baseline, 15 patients presented dysphagia for liquid and solid food and four for solid food only, eight were on parenteral nutrition, and six presented bronchial aspiration (by FEES). The mean PAS score at the first evaluation was 5.2. Ten patients completely recovered swallowing function and returned to their preoperative diet within 1 month, and six did so within 3 months; the other three patients did not complete the follow-up. No patient presented pneumonia. At the 3-month follow-up, one patient presented bronchial aspiration and the mean PAS score was 1.2. This preliminary experience suggests that careful evaluation of swallowing and early rehabilitation may be advisable in these patients

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Tecnologia edilizia e determinazione dei resti lignei da una struttura produttiva della seconda età del Ferro al Bostel di Rotzo (VI)

    The contribution summarizes the data regarding the excavation and the archaeobotanical investigations carried out on an abundant set of charred wooden remains found within the productive structure C1 of the Bostel di Rotzo site, dated to the 3rd-2nd century BC; the anthracological material, mostly found in connection, offered the chance to investigate the construction techniques and the raw materials used for the realization of a wooden floor and of an internal door, exceptionally preserved with its handle still in situ
