A Digital Twin predictive maintenance framework of air handling units based on automatic fault detection and diagnostics
2022
The building industry consumes the most energy globally, making it a priority in energy efficiency initiatives. Heating, ventilation, and air conditioning (HVAC) systems create the heart of buildings. Stable air handling unit (AHU) functioning is vital to ensuring high efficiency and extending the life of HVAC systems. This research proposes a Digital Twin predictive maintenance framework of AHU to overcome the limitations of facility maintenance management (FMM) systems now in use in buildings. Digital Twin technology, which is still at an initial stage in the facility management industry, use Building Information Modeling (BIM), Internet of things (IoT) and semantic technologies to create…
On the hyperbolic limit points of groups acting on hyperbolic spaces
1998
We study the hyperbolic limit points of a groupG acting on a hyperbolic metric space, and consider the question of whether any attractive limit point corresponds to a unique repulsive limit point. In the special case whereG is a (non-elementary) finitely generated hyperbolic group acting on its Cayley graph, the answer is affirmative, and the resulting mapg +↦g −, is discontinuous everywhere on the hyperbolic boundary. We also provide a direct, combinatorial proof in the special case whereG is a (non-abelian) free group of finite type, by characterizing algebraically the hyperbolic ends ofG.
The double uterus associated with an obstructed hemivagina: Clinical management
1991
Abstract The clinical management of It) patients, 9 with uterus didelphys and 1 with complete septate uterus associated with an obstructed hemivagina, is described. The diagnostic evaluation revealed a complete unilateral obstruction in four patients, and an anomalous communication between the two uterovaginal channels in six. In all such patients, the presence of regular menses is frequently misleading, perhaps resulting in unnecessary laparotomy and inadequate or extirpative surgery with negative reproductive consequences. However, diagnosis is simplified if the gynecologist is aware of the malformation. Recommended treatment consists of evacuation of the retained menstruum and excision o…
The Association of Intraoperative driving pressure with postoperative pulmonary complications in open versus closed abdominal surgery patients – a po…
2021
Abstract Background It is uncertain whether the association of the intraoperative driving pressure (ΔP) with postoperative pulmonary complications (PPCs) depends on the surgical approach during abdominal surgery. Our primary objective was to determine and compare the association of time–weighted average ΔP (ΔPTW) with PPCs. We also tested the association of ΔPTW with intraoperative adverse events. Methods Posthoc retrospective propensity score–weighted cohort analysis of patients undergoing open or closed abdominal surgery in the ‘Local ASsessment of Ventilatory management during General Anaesthesia for Surgery’ (LAS VEGAS) study, that included patients in 146 hospitals across 29 countries.…
SAFER et sociétés : trois mariages et un enterrement
2017
International audience; La loi n° 2017-348 du 20 mars 2017 relative à la lutte contre l’accaparement des terres agricoles renforce le pouvoir de surveillance des SAFER sur les appropriations réalisées par les sociétés, mais échoue à étendre leur droit de préemption aux mutations partielles de parts sociales.
L’EBPM nella profilassi del paziente oncologico
2014
Premesse e Scopo dello studio: Valutare il beneficio dell’uso del- l’EBMP nella profilassi del paziente oncologico poiché questi presen- tano un rischio tromboembolico elevato. Metodi e Risultati: Nell’ultimo triennio presso il Dipartimento di Chi- rurgia Generale e di Urgenza dell'Az. Ospedali riuniti Villa Sofia - Cervello sono stati operati per cancro al retto sigma e sottoposti ad intervento di emicolectomia sx e resezione anteriore del retto 87 pazienti di cui 34 uomini e 53 donne, di questi 13 donne e 5 uomini hanno sviluppato durante il follow-up terapeutico oncologico complicanze a carico di sto- mie cutanee. In tutti i pazienti venuti alla nostra osservazione si sono evidenziati a …
Spontaneous bilateral tubal pregnancy in a nulliparous woman. Laparoscopic diagnosis and treatment
2015
A 34 year-old nulliparous woman was referred to our Department, complaining of vaginal bleeding and intermittent lower abdominal cramping. serum level of β-hCG was 4954 IU/L. Transvaginal ultrasound examination revealed no gestational sac in the uterine cavity and a right adnexal mass, suggestive of ectopic pregnancy; left adnexal area appeared regular. At laparoscopy, the presence of an ectopic pregnancy was confirmed in the right tube; on the left side, surprisingly, there was an intact infundibular ectopic pregnancy. Right tuba was removed; considering the condition of nulliparous of the patient, we decided to perform a linear salpingostomy. Histologic exam confirmed the diagnosis of spo…
Educational value of surgical videos on YouTube: quality assessment of laparoscopic appendectomy videos by senior surgeons vs. novice trainees
2019
Background To prepare for surgery, surgeons often recur to surgical videos, with YouTube being reported as the preferred source. This study aimed to compare the evaluation of three surgical trainees and three senior surgeons of the 25 most viewed laparoscopic appendectomy videos listed on YouTube. Additionally, we assessed the video conformity to the published guidelines on how to report laparoscopic surgery videos (LAP-VEGaS). Methods Based on the number of visualization, the 25 most viewed videos on laparoscopic appendectomy uploaded on YouTube between 2010 and 2018 were selected. Videos were evaluated on the surgical technical performance (GOALS score), critical view of safety (CVS), and…

Hysterectomy for Non-Prolapsed Uterus in Elderly Patients: Predictors of Prolonged Hospital Stay
2022
<b><i>Objective:</i></b> The objective of this study was to investigate surgical outcomes and complications of hysterectomy for benign conditions other than prolapse in elderly patients and to define predictors of prolonged hospitalization. <b><i>Design:</i></b> Retrospective analysis of prospectively collected data. <b><i>Setting:</i></b> This study was conducted in an academic research center. <b><i>Patients:</i></b> We utilized our institution surgical database to identify patients aged 60 years or more (“elderly”) who underwent hysterectomy for benign conditions other than pelvic organ prolap…
