Il monitoraggio dei consumi energetici di una città
No full textL’evoluzione delle nostre città verso modelli di Smart City e Smart Land rappresenta per i Comuni una sfida impegnativa, complessa ma anche appassionante per i grandi temi che coinvolge: innovazione, ambiente, energia. La capacità degli Enti locali di immaginare nuovi scenari, organizzare in modo nuovo servizi, spazi ed edifici delle nostre città, riconfigurandone le modalità di fruizione, determina per i cittadini un miglioramento della qualità della vita.
Di questi temi si è discusso nel Laboratorio approfondendo aspetti tecnologici e organizzativi, opportunità di accesso a finanziamenti, best practice e modalità innovative di comunicazione attraverso incontri operativi di presentazione delle esperienze e confronto aperto tra amministratori locali, funzionari della PA, esperti del settore ed aziende
Popularising midwifery and obstetrics in Martha Mears' "Pupil of Nature" (1797)
No full textBetween the seventeenth and eighteenth centuries, major sociocultural changes affected the domain of medicine as an area of expertise and praxis and paved the way for new modes of constructing and disseminating knowledge which dramatically differed from the medieval, scholastic, logocentric science derived from Galen, Hippocrates, and other ancient writers (Patha and Taavitsainen 2011). The popularisation of medicine also involved linguistic changes, which naturally need to be contextualised according to such criteria as time, place, the role of speakers/hearers or writers/readers, purpose, and the prevailing scientific ideologies (or thought-styles) of the time. Within this area, midwifery and obstetrics manuals seem to occupy a significant niche which perfectly exemplifies this process; this paper proposes an analysis of Martha Mears’ Pupil of Nature, or, Candid Advice to the Fair Sex (1797) and of the (linguistic) popularisation strategies used by the author in order to render the discipline more accessible to the (new) female audience. Mears’ sensible approach to the subject of pregnancy and childbirth was aimed at creating an alternative public sphere in which women practitioners stood at the threshold between domesticity and state and served their duty both to mothers and the community (Forman Cody 1999), in spite of the prevailing ideologies of the time and the gendered disputes between them and the so-called “men-midwives” (Fife 2004). The manual will be compared to William Smellie’s Treatise on Midwifery (1752), which is generally acknowledged among the foregrounding works on obstetrics, and the study will highlight how differences in contexts, actors, readership, language (e.g. the use of Latin and/or the “vernacular” English; technical vocabulary; repetition; metaphors, etc.) can be accounted for as displays of the ongoing developments in the popularisation of science in late eighteenth-century Britain
Univariate and bivariate symbolic analyses of cardiovascular variability differentiate general anesthesia procedures
No full textGeneral anesthesia attenuates autonomic function and baroreflex control. This side effect should be prevented as much as possible because it limits the subject's ability in responding to physiological challenges during surgery (e.g. arterial pressure and ventricular contractility drops). This study is designed to rank two of the most commonly exploited general anesthesia treatments, i.e. intravenous anesthesia (IA) based on a propofol-opioid combination and volatile anesthesia (VA) based on a sevoflurane-opioid combination, according to their ability to maintain autonomic nervous system activity and baroreflex control. Univariate and bivariate symbolic techniques were applied to spontaneous heart period (HP) and systolic arterial pressure (SAP) variability series recorded during IA and VA procedures in 19 and 18 patients undergoing elective intracranial neurosurgery. Traditional linear univariate and bivariate frequency domain markers of the autonomic nervous system state and baroreflex control were evaluated as well. We found that: (i) univariate symbolic analysis of HP series suggests a better preservation of vagal modulation in VA than in IA; (ii) bivariate symbolic markers assessing the degree of HP-SAP association differentiate IA from VA, while baroreflex sensitivity and squared coherence function cannot; (iii) bivariate symbolic analysis indicates a better preservation of the HP-SAP association at slow frequencies in IA than in VA, thus suggesting a more active baroreflex control in IA. We conclude that symbolic indexes can be fruitfully exploited to rank general anesthesia treatments, and their performance appears to be superior to that of more traditional linear markers
Impact of uncertainty in rainfall estimation on the identification of rainfall thresholds for debris flow occurrence
No full textEstimation of rainfall intensity–duration thresholds, used for the identification of debris flow/landslide triggering rainfall events, has been traditionally based on raingauge observations. The main drawback of using information from gauges is that the measurement stations are usually located far away from the debris flow initiation areas. In complex terrain where debris flows take place, the spatial variability of rainfall can be very high and this translates in large uncertainty of raingauge-based estimates of debris flow triggering rainfall. This work focuses on the assessment of the impact of rainfall estimation uncertainty on identification and use of rainfall thresholds for debris flow occurrence. The Upper Adige River basin, Northern Italy, is the area of study. A detailed database of more than 400 identified debris flow initiation points during the period 2000–2010 and a raingauge network of 100 stations comprise the database used for this work. The methodology examines the intensity–duration thresholds derived from a set of raingauges that are assumed to be located at debris flow initiation points (DFRs) and an equivalent set of raingauges assumed to have the role of the closest (to debris flow) available measurement (MRs). A set of reference rainfall thresholds is used to identify the rainfall events at DFRs that “triggered” debris flows (i.e. exceed the threshold). For these same events, the corresponding rainfall thresholds are derived from MR observations. Comparison between the rainfall thresholds derived from DFRs and MRs revealed that uncertainty in rainfall estimation has a major impact on estimated intensity–duration thresholds. Specifically, the results showed that thresholds estimated from MR observations are consistently underestimated. Evaluation of the estimated thresholds for warning procedures showed that while detection is high, the main issue is the high false alarm ratio, which limits the overall accuracy of the procedure. Overall performance on debris flow prediction was shown to be good for low rainfall thresholds and poor for high rainfall thresholds examined. Lastly, it was found that filtering out rainfall events with duration b12 h may improve bias in estimated thresholds and performance for high rainfall thresholds

No full textSymbolic analysis of heart rate variability differentiates anesthesiological procedures
No full textThe present study exploited symbolic analysis of heart period (HP) variability during three different anesthetic strategies during neurosurgical procedures. We monitored HP variability in 93 patients during elective neurosurgical procedures. Patients were randomly assigned to three anesthetic strategies: sevoflurane+fentanyl (S-F), sevoflurane+remifentanil (S-R) and propofol+remifentanil (P-R). All anesthetic strategies were characterized by a reduction of HP variability. An increased presence of stable patterns was detected in the P-R group. Conversely, an increased presence of instable patterns was present in the second hour of surgery in S-F group. Despite an important reduction of HP variability, the symbolic analysis differentiates anesthetic strategies
