Quantifier elimination and other model-theoretic properties of BL-algebras

This work presents a model-theoretic approach to the study of firstorder theories of classes of BL-chains. Among other facts, we present several classes of BL-algebras, generating the whole variety of BL-algebras whose firstorder theory has quantifier elimination. Model-completeness and decision problems are also investigated. Then we investigate classes of BL-algebras having (or not having) the amalgamation property or the joint embedding property and we relate the above properties to the existence of ultrahomogeneous models. © 2011 by University of Notre Dame.Peer Reviewe

Agricoltura e allevamento nell’Italia medievale. Contributo bibliografico, 1950-2010

The bibliography proposed takes into account the historiographical works on Middle Ages (VI-XV centuries) of the years 1950-2010: these are years particularly significant for the development and consolidation of studies relating to Italian (and more generally European) agricultural history. In order to facilitate the consultation, the work is organized into chapters and thematic sections, preceded by a brief explanatory note which gives an account of the criteria used to identify the listed works. The Introduction presents thoughts on the salient moments of the historiographical history at the heart of the contemporary discussion

Preoperative smoking cessation program in patients undergoing intermediate to high-risk surgery: a randomized, single-blinded, controlled, superiority trial

BACKGROUND At present, effectively implementing smoking cessation programs in the health care system constitutes a major challenge. A unique opportunity to initiate smoking cessation focuses on smokers scheduled for surgery. These patients are not only highly motivated to quit smoking but also likely to benefit from a reduction in postoperative complications which may translate into a decrease of costs. Nevertheless, surgical patients are not routinely informed about the benefits of preoperative smoking cessation. Potential reasons for this missed opportunity may be the lack of time and training of surgeons and anaesthesiologists. We therefore aim to analyse the impact of a preoperative high-intensity smoking cessation intervention on surgical complications up to a 90-day postoperative period in patients of various surgical disciplines. The hypothesis is that a preoperative smoking cessation program improves outcomes in smokers undergoing intermediate to high-risk surgery. METHODS The present study is a single-centre, randomized trial with two parallel groups of smokers scheduled for surgery comparing surgery alone and surgery with preoperative smoking cessation. We plan to randomize 251 patients. The primary objective is to compare complications between patients with an institutional multifaceted smoking cessation intervention starting 4 weeks before surgery compared to patients in the advice-only group (control group) within a 90-day postoperative period. The primary endpoint is the Comprehensive Complication Index (CCI®) within 90 days of surgery. Secondary outcomes include the length of hospital stay, cost of care, quality of life, smoking abstinence, and reduction in nicotine consumption. DISCUSSION The hypothesis is that a preoperative smoking cessation program improves outcomes in smokers undergoing surgery. TRIAL REGISTRATION BASEC #2021-02004; ClinicalTrials.gov: NCT05192837 .

Agricoltura e allevamento nell'Italia medievale. Contributo bibliografico, 1950-2010

ITALIANO: Il contributo bibliografico proposto considera la produzione storiografica di riferimento medievale (secoli VI-XV) degli anni 1950-2010: sessant’anni particolarmente significativi per lo sviluppo e il consolidamento degli studi relativi alla storia agraria italiana (e più generalmente europea). Al fine di agevolare la ricerca, è organizzato in capitoli e sezioni tematiche, preceduti da una breve nota esplicativa che rende conto dei criteri utilizzati per l’individuazione delle opere in elenco. Nell’Introduzione si sviluppano riflessioni sui momenti salienti della vicenda storiografica al centro dell’attenzione. / ENGLISH: This proposed bibliographical contribution considers the historiographical output pertaining to the Middle Ages (VI-XV centuries) of the years spanning from 1950 to 2010: sixty years which were particularly important for the development and cementing of studies into Italian agrarian history (and more broadly-speaking European). For the purpose of facilitating research, this work has been divided into chapters and theme-based sections, preceded by a brief explanation of the criteria adopted in identifying the listed works. In the Introduction, an analysis is undertaken of the historiographical highlights of the issues at the very core of this study
