Cross-sectional associations of objectively-measured sleep characteristics with obesity and type 2 diabetes in the PREDIMED-Plus trial.
2018
Study Objectives: To examine independent and combined associations of sleep duration and sleep variability with body composition, obesity and type 2 diabetes (T2D) in elders at high cardiovascular risk. Methods: Cross-sectional analysis of 1986 community-dwelling elders with overweight/obesity and metabolic syndrome from PREDIMEDPlus trial. Associations of accelerometry-derived sleep duration and sleep variability with body mass index (BMI), waist circumference (WC) and body composition were assessed fitting multivariable-adjusted linear regression models. Prevalence ratios (PR) and 95% confidence intervals (CI) for obesity and T2D were obtained using multivariable-adjusted Cox regression w…
The efficacy of BCG TICE and BCG Connaught in a cohort of 2,099 patients with T1G3 non–muscle-invasive bladder cancer
2016
BACKGROUND Potential differences in efficacy of different bacillus Calmette-Guerin (BCG) strains are of importance for daily practice, especially in the era of BCG shortage. OBJECTIVE To retrospectively compare the outcome with BCG Connaught and BCG TICE in a large study cohort of pT1 high-grade non-muscle-invasive bladder cancer patients. DESIGN, SETTING, AND PARTICIPANTS Individual patient data were collected for 2,451 patients with primary T1G3 tumors from 23 centers who were treated with BCG for the first time between 1990 and 2011. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Using Cox multivariable regression and adjusting for the most important prognostic factors in this nonrandomiz…
Anesthesia protocols in laboratory animals used for scientific purposes
2018
Background: A suitable, effective and free of complications anesthetic protocol is very important in experimental studies on animal models since it could bias the outcome of a trial. To date there is no universally accepted protocol for induction, maintenance and recovery from anesthesia. The endotracheal intubation with the use of inhalation anesthesia is used very especially in the from of large size laboratory animals, because it is a secure and easy control mode. However, it is not common for small laboratory animals because of the high technical skills required. Aim: The aim of this paper is a review of the main methods of induction of anesthesia in laboratory animals. Materials and me…
Suitability of some existing damage indexes for assessing agreements in maintenance and management of museum climatization systems
2020
Heating, Ventilating and Air-Conditioning systems in museums are called to properly control important microclimate parameters, not only for visitors’ wellbeing, but mostly for the preservation of works of art. Accordingly, in case of interruptions to Heating, Ventilating and Air-Conditioning systems, due to maintenance interventions or drawbacks, it is essential to guarantee the acceptable break from service to which possible damages for the works of art are related. In this regard, the aim of this work is to introduce a simple indicator to support curators in regulating the stipulation of contracts with external companies, a more effective management and maintenance of the Heating, V…
Proposition du Project APER pour un entretien programé du Quartier hellénistique-romain d’Agrigente / Proposta del Progetto APER per la manutenzione …
2014
The article puts forward a proposal for the planned maintenance of the Sicilian study case chosen by the APER Project: House IA-B in Agrigento’s Hellenistic-Roman Quarter. After a few brief considerations regarding maintenance work on buildings and on architectural heritage, specific details concerning the maintenance of archaeological sites are illustrated. The article proposes a coding system specially applied to domestic Punic, Hellenistic and Roman architecture, designed to identify maintenance units, meaning parts of the archaeological built environment that can be the object of effectively planned maintenance work because they feature similar shapes and materials. This proposal should…
A Survey of Current Measurement Methods for eGovernment User-Satisfaction
2011
A survey on eGovernment user-satisfaction measurement methods was conducted to enable a comparison among them and to facilitate a discussion on good practices. The collected information is related to the methodology properties, tools, followed practices, implementation stage and challenges. The main findings are that the surveyed methods rarely refer to any established relevant standards, they are not regularly updated, and most of them do not have an open process for maintenance. We also note that software vendors are mostly not included in the intended group of users of the measurement results. A revision of methods and their maintenance processes can increase their accountability and ena…
Towards farm-level health management of offshore wind farms for maintenance improvements
2015
This paper studies a conceptual architecture for health management of offshore wind farms. To this aim, various necessary enablers of a health management sys- tem are presented to improve reliability and availability while optimizing maintenance costs. The main focus lies on improving existing condition monitoring systems based on concepts of condition-based maintenance and relia- bility centered maintenance. A brief review of the rel- evant state-of-the-art is presented and gaps to be filled towards realization of such health management system are discussed.
Seminars on Software Maintenance and Evolution: An Empirical Study of the Background Factors Affecting Student Success
2013
Software maintenance and evolution (SME) is an important but challenging topic area for university-level computer science education. Seminars can be used to provide students with versatile and up-to-date knowledge on scien- tifically relevant issues. We organized three systematic university-level seminars on SME. In these seminars 127 groups have each been assigned the task of analyzing one scientific SME article. The main results concern background factors re- lating to the students, groups and articles as these affect student success in the seminars. This paper presents a strict statis- tical analysis and a discussion of these factors. Fourteen hypotheses were set and tested regarding the…
Il monastero di Santa Caterina d’Alessandria di Palermo: conoscere per conservare

Il saggio indaga il complesso monumentale di Santa Caterina d’Alessandria, di Palermo, che costituisce uno dei più antichi monasteri di clausura della città. Il contributo è il frutto della ricerca condotta da Renata Prescia e Rosario Scaduto e presentata nel catalogo della mostra Sacra et preziosa Orificeria dai monasteri di Palermo capitale, tenutasi nel Monastero di Santa Caterina d’Alessandria di Palermo, 28.12.2018-31.05.2019. Grazie alla convenzione sottoscritta dal Dipartimento di Architettura e la Soprintendenza per i Beni Culturali e Ambientali di Palermo è stato possibile effettuare un particolareggiato rilievo dello stato di conservazione del monumento e presentare dei progetti p…
Clustering-Based Algorithm for Connectivity Maintenance in Vehicular Ad-Hoc Networks
2014
International audience; Among recent advances in wireless communication technologies' field, Vehicular Ad-hoc Networks (VANETs) have drawn the attention of both academic and industry researchers due to their potential applications including driving safety, entertainment, emergency applications, and content sharing. VANET networks are characterized by their high mobile topology changes. Clustering is one of the control schemes used to make this global topology less dynamic. It allows the formation of dynamic virtual backbone used to organize the medium access, to support quality of service and to simplify routing. Mainly, nodes are organized into clusters with at least one cluster head (CH) …
