Una lettera di esortazione alla "viva fede" in Gesù Cristo nell'Istria di metà Cinquecento

La lettera è oggi conservata nella busta 4, nella quale sono raccolti in modo un po' caotico documenti e fascicoli processuali, che vanno dal gennaio del 1545 al 1568, collegati in certo modo alle vicende di Pier Paolo Vergerio, vescovo di Capodistria, processato dal nunzio apostolico Giovanni Della Casa per eresia dal 2 gennaio 1545 all'agosto del 1547, condannato definitivamente dal papa come eretico formale alla privazione del vescovato nel giugno del 1549, e a quelle di molti istriani che furono processati contemporaneamente e dopo di lui. L'ordinamento del fondo Inquisizione li considerò un blocco unico riguardante il Vergerio, ma in realtà si tratta di cause giuridicamente distinte e cronologicamente distanti. La lettera indirizzata da Ioseph da Faenza "Al pr.te (?) ser Zuane de Bertuci de ser Nicolò, suo in Christo fratello", a Pirano, si trova nel fascicolo archivistico "Pier Paolo Vergerio. Taidino Giovanni prete, Zanoni Giorgio, Greco Giorgio, Mercanzutti Giorgio, Tessaro Biagio, Castagna Marco, De Vittori Bono, Da Paderno Giuseppe, De Zanotti Giovanni, Valtollina Veronesa, Da Lesina Giovanni", secondo quanto sta scritto sulla camicia

experimental and numerical study of a parabolic trough linear cpvt system

Abstract The electric and thermal performance of a parabolic trough linear concentrating photovoltaic-thermal (CPVT) system operating in Padova (northern Italy) is experimentally investigated. The system moves about two axes and exhibits a geometrical concentration ratio around 130. The receiving module placed on the focus line displays a secondary optics made of two flat mirrors to gather some reflected radiation and to contribute to the concentrated flux on two lines of triple junction photovoltaic cells soldered on a ceramic substrate. The substrate is in thermal contact with a aluminium heat exchanger with water flow channels to cool the PV cells. During the test runs, the inlet water temperature ranges from 20 °C to 80 °C and the heat yield is obtained from mass flow rate and temperature measurements while a rheostat and a power analyzer are connected to the electric terminals of the module to assess the electrical production. The direct normal irradiation (DNI) is measured by a pyrherliometer mounted on a solar tracker. Experimental results are used to assess a numerical model of the solar receiver and the whole concentrator

DNI Estimation Procedures for the Assessment of Solar Radiation Availability in Concentrating Systems

Abstract DNI (Direct Normal Irradiance) is the resource utilized by solar concentrators. Besides, the determination of DNI is needed in the models for the estimation of global irradiance on tilted planes, which is the input to flat-plate systems. This paper describes a study of different estimation procedures for the assessment of the DNI , using experimental data with a time scale of 1 min, taken at two different latitudes. The analyzed approaches include measuring techniques and models. The results show that the different estimation methods can lead to quite different conclusions when comparing the solar radiation availability in concentrating and flat-plate systems and this can affect the energy and economic evaluations. Based on the experimental analysis, indications for reducing the uncertainty in the estimation of DNI are discussed

A New Model for the Analysis of Performance in Evacuated Tube Solar Collectors

Solar collectors can provide a useful response to the heat demand in buildings, such as heating of domestic water and spaces. Among the different types of solar collectors, the evacuated tube ones can better display their features when the temperature difference between operating fluid and ambient air is high, which are the typical operating conditions during space heating of buildings. Beside the heating application, there is also need for addressing the increasing energy consumption due to the summer air conditioning. Solar cooling can be an interesting opportunity, because the cooling demand matches the period with the higher solar radiation availability. Also in this application the evacuated collectors are an adequate type, due to the temperature level of the heat required as an input to the absorption machines. Therefore, accurate modeling and simulation of this type of collectors is highly recommended to fully assess the performance of the collectors already available in the market and propose improved designs, for example with higher concentration ratio, to get more benefits particularly at higher levels of temperature. This paper reports a new model for the performance analysis of evacuated tube solar collectors. The analyzed collectors are truncated CPC (compound parabolic collectors). An original software is developed under MATLAB environment for the simulation purposes. A novel numerical procedure is implemented to obtain the solution for the nonlinear set of equations representing the mathematical model. The length of the tube is divided into a specified number of segments. The analysis is performed for each segment along the tube length in order to obtain the variation of the different parameters. The model analyzes separately the optics and the heat transfer in the evacuated tubes and this approach allows to extend the analysis to new configurations. The model can simulate the efficiency curve under steady state conditions, according to the standard EN 12975-2 (EN 12975-2. Thermal solar systems and components - solar collectors - part 2: test methods. Brussels: CEN; 2006), but it is also able to describe the performance during the day with a quasi-dynamic approach. A comparison with experimental data shows the accuracy of the model. The results will provide a comprehensive characterization of the performance of evacuated tube collectors, discussing modeling and experimental data of efficiency and heat production at different levels of temperature. Particular attention will be paid to the applications of heating and cooling of buildings, industrial process heat generation and district heating

Modeling of dropwise condensation on flat surfaces

There are two ways for a vapor to condense on a surface: filmwise condensation (FWC) and dropwise condensation (DWC). The interest in DWC is based on the potential increase of the condensation heat transfer coefficient (HTC) by 6 to 10 times compared to the values measured during filmwise condensation. For this reason, several research groups around the world have tried to promote the dropwise condensation and to describe the underneath mechanisms. Such models describe the phenomena that take place during dropwise condensation: the nucleation of a droplet until its departure, the heat exchanged by the drop during its lifetime and the droplets population on the surface. The present paper aims at presenting some of the models developed in the past years which can be used to describe the DWC process. In particular, similarities and differences between the models are highlighted and their predictions are compared against experimental data measured at the Two-phase Heat Transfer Laboratory of the University of Padova.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers

Psychological and behavioral disease during developmental age: the importance of the alliance with parents

The aim of the study is to analyze the clinician’s alliance with parents during the diagnostic process in relation to therapeutic compliance and clinical evolution of individuals aged 0–11 years. The sample was formed by 84 individuals aged 0 to 11 years (18 < 6 years, 66 aged 6 to 11 years; 62 males and 22 females) who came to the Neuropsychiatric Unit for Children and Adolescents for a consultation regarding psychorelational and behavioral problems. Neuropsychiatric consultation took place in five diagnostic interviews with child and parents, separately. The last session was devoted to communication of psychiatric diagnosis (according to ICD 10) and therapeutic suggestions, if any. The clinician’s relationship with parents and patients’ participation were evaluated in terms of collaboration and quality of interaction, on the basis of pre-established criteria. Data about patients’ therapeutic compliance and clinical outcome were collected during a follow-up visit eight months after the last session. Results suggest that the better the alliance between parents and clinician, the higher the therapeutic compliance and the likelihood of a positive outcome for patients. Our data suggest that good communication with parents benefits child patients, both in terms of response to the parents’ need to report their children’s worrying behavior and as a response to the discomfort expressed by children when they come in for consultation

Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register

Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations

Antidiabetic Drug Prescription Pattern in Hospitalized Older Patients with Diabetes

Objective: To describe the prescription pattern of antidiabetic and cardiovascular drugs in a cohort of hospitalized older patients with diabetes. Methods: Patients with diabetes aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro POliterapuie SIMI—Società Italiana di Medicina Interna) registry from 2010 to 2019 and discharged alive were included. Results: Among 1703 patients with diabetes, 1433 (84.2%) were on treatment with at least one antidiabetic drug at hospital admission, mainly prescribed as monotherapy with insulin (28.3%) or metformin (19.2%). The proportion of treated patients decreased at discharge (N = 1309, 76.9%), with a significant reduction over time. Among those prescribed, the proportion of those with insulin alone increased over time (p = 0.0066), while the proportion of those prescribed sulfonylureas decreased (p &lt; 0.0001). Among patients receiving antidiabetic therapy at discharge, 1063 (81.2%) were also prescribed cardiovascular drugs, mainly with an antihypertensive drug alone or in combination (N = 777, 73.1%). Conclusion: The management of older patients with diabetes in a hospital setting is often sub-optimal, as shown by the increasing trend in insulin at discharge, even if an overall improvement has been highlighted by the prevalent decrease in sulfonylureas prescription

The “Diabetes Comorbidome”: A Different Way for Health Professionals to Approach the Comorbidity Burden of Diabetes

(1) Background: The disease burden related to diabetes is increasing greatly, particularly in older subjects. A more comprehensive approach towards the assessment and management of diabetes’ comorbidities is necessary. The aim of this study was to implement our previous data identifying and representing the prevalence of the comorbidities, their association with mortality, and the strength of their relationship in hospitalized elderly patients with diabetes, developing, at the same time, a new graphic representation model of the comorbidome called “Diabetes Comorbidome”. (2) Methods: Data were collected from the RePoSi register. Comorbidities, socio-demographic data, severity and comorbidity indexes (Cumulative Illness rating Scale CIRS-SI and CIRS-CI), and functional status (Barthel Index), were recorded. Mortality rates were assessed in hospital and 3 and 12 months after discharge. (3) Results: Of the 4714 hospitalized elderly patients, 1378 had diabetes. The comorbidities distribution showed that arterial hypertension (57.1%), ischemic heart disease (31.4%), chronic renal failure (28.8%), atrial fibrillation (25.6%), and COPD (22.7%), were the more frequent in subjects with diabetes. The graphic comorbidome showed that the strongest predictors of death at in hospital and at the 3-month follow-up were dementia and cancer. At the 1-year follow-up, cancer was the first comorbidity independently associated with mortality. (4) Conclusions: The “Diabetes Comorbidome” represents the perfect instrument for determining the prevalence of comorbidities and the strength of their relationship with risk of death, as well as the need for an effective treatment for improving clinical outcomes
