Full textMinor poet of the fifteenth-sixteenth century between boiardo and ariosto, the cieco seems to have worked principally for a gonzague's secondary court and may be for the este. His only one work which remains today is the mambriano, chivalric poem probably written between 1490 and 1502, which has had a great commercial success. In spite of an apparent difference between the first and the second part, the poem appears relatively structured, and its analysis shows both a great dependance from the rhetoric canterina and an imitation of boiardo. For a part the interest of this poem lies in the insertion in the warrior adventures of some short stories, clearly erotics and comicals, which contribute to lighten the narration with a calculated effect of variatio. In spite of the insertion of saucy metaphor and of a process of reduction for the characters in relation to the tradition, the poem is willingly moralizing; and it is one of its principals characteristics. For all that, its success during the sixteenth century is so important that, later, great poets like ariosto and tasso will draw one's inspiration from some episodes of the mambriano. For all these reasons, the cieco marks a real stage in the chivalric poem's evolution between boiardo and ariosto

Full textThe purpose of this work was the analysis and the mathematical description of energy absorption and dissipation processes in magnetorheological shock absorbers submitted to cyclic loading. The influence of control, construction and exploitation parameters, and the development of procedures allowing the optimization of the device operation have been investigated. Conducted experiments allowed to determine the performance of a magnetorheological damper as a function of basic parameters such as the crevice size inside the damper’s piston head, the electric current intensity in the magnetic coil and the oscillation speed of forced kinematical input motion function. The computer simulation of the damper’s operation has been carried out with the use of two rheological models: of Bouc-Wen and a modified version of simplified Gamot-Filisko. Results of both approaches have been compared in terms of quantity and quality. In order to identify the parameters of the model, the simulated annealing optimization method has been applied. The changes of identified parameters of the rheological model have been presented graphically as surfaces of variation. The extrapolation of these surfaces allowed extending the domain of searched solutions beyond the available range of experimental results. Characteristic izolines’ configurations of model variables have been observed. Basing on this observation, a method of analysis and a way of parameters selection have been presented. The proposed methodology can be useful during design process, comparison and optimization of magnetorheological fluid device operation parameters

Full textThis PhD thesis contains the results of systematic research, the main purpose of which was to better understand the influence of variable thermodynamic conditions on the dynamics of glass transition and the kinetics of crystallization of low-molecular substances forming the glassy state. By variable thermodynamic conditions were understood here a modification of the thermodynamic parameters of the system as a result of compression as well as the use of spatial limitations of the order of "nano". It is worth to noting that in both cases it should expect significant changes in density of molecular packing, as well as changes in the nature of molecular interactions, which can influence in a significant way (not necessarily the same) into dynamic properties of the tested materials near the transition glassy as well as their crystallization behavior. The effects associated with density fluctuations are next to temperature effects the key to understanding the glass transition and crystallization processes, because even the phase diagrams of substances are two-dimensional (T, ρ), not onedimensional. Thus, the application of such an approach to the performed research allowed to look at many issues related to the dynamics of glass transition and attempts to control/modify the tendency to crystallize/vitrify the tested materials in a completely new, more synthetically way. This work is experimental in nature and is based on the results of research obtained primarily using the dielectric spectroscopy. This method is an ideal tool for studying the molecular mobility of liquids and glasses in a wide range of relaxation times as well as monitoring the kinetics of crystallization or phase transition detection. However, in the context of the conducted research, its main advantage was the relative ease of adaptation to tests conducted in the conditions of elevated pressure reaching even 1.5 GPa (!), As well as geometry limited to the "nano" scale (liquid trapped in nanoporous matrices with a pore size a dozen or several dozens nanometers). The paper presents how the increased pressure affects the dynamics of the glass transition process and the crystallization process of two model, glass-forming substances (i) propylene carbonate and (ii) fenofibrate. The most important results that have been obtained include (i) showing, in analogy to temperature measurements carried out at atmospheric pressure, the important role of the compression/decompression rate on the tendency to form glassy state/crystallization in the isothermal conditions, and showing that (ii) through skillful controlling parameters such as temperature and pressure, or choosing the thermodynamic path is possible to directly affect on the crystallization process and the obtained products. This will be particularly important, especially in the context of fenofibrate belonging to the group of cholesterol lowering drugs, which shows a rich polymorphism, what which can have a significant impact on the therapeutic effect. In this case, favoring only one selected polymorphic form, or in general, controlling the crystallization behaviors of glassforming materials using compression techniques can have important application importance. Just an interesting experimental results were provided by research conducted in limited geometry. First of all, they confirmed the latest scientific reports suggesting that the dynamics associated with the glass transition in a nanoporous medium may be subject to the same principles as supercooled macroscopic liquids. This is especially about the idea of density scaling and isochronal superposition. Nevertheless, the results of the research that was obtained as part of this doctoral dissertation call into question grated in the literature conviction that meeting one of the above rules also means fulfilling the second rule. In turn, studies on crystallization kinetics conducted for liquids trapped in nanoporous matrices showed that with the reduction of the pore size, we observe many significant changes concerning the process of the crystallization process, e.g. changes the shape of the crystallization curve from sigmoidal to exponential, decreases the value of the crystallization rate constant and the Avrami parameter, and shifts towards lower temperatures/higher subquench the maximum of crystallization rate constant. Thus, "confined" effects can play also an important role as pressure effects when it comes to the possibility of better and more conscious controlling of the tendency to crystallize glass forming materials. The obtained results bring a very high cognitive value, especially due to the fact that in the literature there is a lack of such systematic research devoted to behavior of materials forming the glassy state in various thermodynamic conditions. This may be proved by the fact that some of them concerning the influence of spatial constraints on the course of the crystallization process were strongly emphasized in the recent review on the crystallization of amorphous materials by prof. Descamps fromFrance (Int. J. Pharm. 542 (2018) 186-195).The results collected during the preparation of the present PhD thesis allow to look at the glass transition and crystallization processes in context of changes not only in temperature/thermal energy, but also density of packing molecules (generated using two alternative strategies, twodimensional spatial limits of the "nano" and elevated pressure). It is worth noting that only through such a combination it is possible to obtain a coherent and complete description of both considered processes, as well as methods for controlling/modifying the crystallization behavior of materials depending on the application or future applications.

Full textPapayas (Carica papaya L.) of \"Sunrise solo\" variety are fruits that present gradual and uneven changes in the peel color, which goes from green to yellow. As a consequence, when using a colorimeter to quantify their color, the results are subjective because of the number of observed points, as well as because of their position on the fruit. A proposed alternative was to use scanned images of the whole fruit peel to quantify color. To assess the precision of these methods, an experiment with 20 replicates was carried out. Each replicate consisted of a papaya fruit, kept under controlled temperature and relative humidity. The fruits\' peel colors were assessed, daily, using a colorimeter and a scanner. With the scanner, both sides of the fruit were scanned and, with the colorimeter, four equidistant points at the equatorial region of the fruit were observed. As the assessment was made through time for a same fruit, the data are classified as longitudinal. Therefore, linear mixed effect models were used to study the behavior of the average fruit color tonality through time, as this technique allows usage of different random effects and error covariance structures. Model selection was made using likelihood-ratio tests and the Akaike and Bayesian information criteria, which resulted in the selection of the same linear predictor and covariance matrices for both color quantification methods. The final model presented a quadractic linear predictor with random effects for the intercept, linear and quadractic terms with an unstructured variance-covariance matrix for the random effects and a variance components with heterogeneity matrix for the residuals. The use of a scanner revealed two distinct phisiological maturation groups, which may be related to the harvesting time. This was not observed when using a colorimeter. In general, using a scanner made possible to obtain more consistent observations, which makes it a more efficient methodology to study the average fruit peel color tonality.

Full textThe aim of the present study is to define the development of the comedy of Plauto-Terencian origin after the Council of Trent. It will examine the comedies of Luigi Groto, comparing them with other comedies of the Sixteenth Century. There was a reinvention of the comedy based on the Plautian model in the first half of the Cinquecento. The model (called motoria), which was full of effects and lively with action, was adapted to the needs of the era and the public taste. Subsequently this model was enriched by patterns of the Terencian comedy called stataria. The stataria, differently from the motoria, gave more room to characters and to reflections of the comedy itself. Some playwrights, i.e. Angelo Beolco and Pietro Aretino, both fundamental for the study, followed this development in their plays. The three comedies that we are going to analyse, differ from each other. Every chapter is going to examine only one comedy and only from one point of view. In the first chapter, we are going to analyse the language of comedy that Groto proposed in the La Emilia (1579). This play is based on Ludovico Aroisto's elaboration of Plautus. In the second chapter, we are going to look at different perceptions of female characters in the Il Thesoro (1583), Groto's second comedy. We will see how the change in the importance of women on stage modified the other characters. In the last chapter we are going to interpret how the La Alteria (1587), based on Terence and Aretino, became a pure metacomedy, and how its hedonistic structure was influenced by Ariosto, Aretino and Beolco.

Full textPURPOSE. This is a prospective double blind, placebo controlled study, based on an original placebo technique, aimed to evaluate the efficacy of percutaneous tibial nerve stimulation (PTNS) in female patients with detrusor overactivity incontinence. PATIENTS AND METHODS. 35 female patients presenting with detrusor overactivity incontinence non responding to antimuscarinic therapy, were randomly assigned either to PTNS or to control group. PTNS group (18 patients) was treated with 12 PTNS sessions. Control group (17 patients) underwent an original placebo treatment, using a 34 G needle placed in the medial part of the gastrocnemius muscle. The sessions lasted for 30 minutes and were performed 3-times per week as PTNS sessions. All patients were evaluated with bladder diaries and quality of life scores (I-QoL) before and after treatment. Patients showing a reduction >50% of urge incontinence episodes were considered responders. RESULTS. 3 patients (1 in PTNS group and 2 in placebo group) did not complete the study for reasons not related to the technique. 12/17 patients (71%) in PTNS group and 0/15 in placebo group (p<0.001) were considered �responders� according to the previously reported definition. Improvement in number of incontinence episodes, number of voids, voided volume and I-QoL score were statistically significant in PTNS group but not in placebo group. CONCLUSIONS. PTNS can be considered an effective treatment of detrusor overactivity incontinence with 71% of patients considered responders, whilst none of the patients treated with placebo was considered responders. The relevance of a placebo effect seems to be negligible in this patient population.

"Studio sperimentale di fase IV monocentrico randomizzato in doppio cieco di confronto tra ketamina e remifentanil per l'analgosedazione di pazienti ventilati invasivamente in terapia intensiva."

Full textSebbene in letteratura ci siano molti studi di confronto tra l'efficacia di differenti regimi analgosedativi in ambito intensivistico e durante procedure chirurgiche in parte complesse, al momento non c'è alcun lavoro focalizzato sul paragone diretto tra ketamina e remifentanil, somministrate in infusione continua e in associazione a propofol, in termini di abilità nel garantire un'efficace sedazione e controllo del dolore in pazienti critici, ricoverati in TI e ventilati meccanicamente per più di 24h. Quando la ketamina viene utilizzata in ICU, la somministrazione è in genere a boli e nulli sono i lavori basati sul suo impiego a "lungo-termine" in associazione a propofol. Alcuni studi preliminari hanno dimostrato che la ketamina gioca anche un ruolo importante nella riduzione dell'incidenza di delirio e depressione dopo lunghi periodi di ricovero in ambito ospedaliero, o se somministrata prima dell'inizio di un intervento di chirurgia maggiore negli adulti, soprattutto di età > 65 anni, e durante chirurgia pediatrica. Abbiamo proposto quindi uno studio clinico sperimentale, monocentrico, randomizzato, basato sull'arruolamento di pazienti ricoverati in ISTAR 1 e 2, due rianimazioni polivalenti (direttore: Prof. C. Ori) dell'Azienda Ospedaliera di Padova. L'attività di ricerca si è basa su un confronto diretto tra due protocolli analgo-sedativi differenti (ketamina+propofol in infusione continua vs remifentanil+propofol) in pazienti critici ventilati meccanicamente per un periodo massimo di 7 giorni e minimo di 36 ore. Nello specifico gli obiettivi di studio sono stati di indagare ed approfondire: - l'abilità del farmaco in infusione continua di raggiungere e mantenere un valore target di RASS tra -2 and 0 durante i primi 7 gg (valore atteso: stesso livello di efficacia di ketamina vs remifentanil o di non inferiorità); - l'incidenza di delirio nei 7 gg e a lungo termine (valore atteso: superiorità di ketamina); - monitoraggio comfort o sofferenza del paziente durante ventilazione meccanica (tramite Critical Care Pain Observational Tool, CCPOT) - incidenza di delirium a breve termine (nei primi 3 gg dopo l'estubazione) (ICU-Confusion Assessment Method, ICU-CAM) - incidenza di deficit cognitivo/delirium alla dimissione dalla TI (Mini Mental Status Exam-test, MMSE) - incidenza di tolleranza/iperalgesia durante i primi 7 gg o sindrome astinenziale - incidenza di depressione cardiovascolare durante i primi 7 gg - durata della ventilazione meccanica - durata della degenza in ICU e mortalità in ICU - tollerabilità della NE ed effetti avversi durante l'analgosedazione - incidenza depressione a 3mesi (Hospital Anxiety Depression Scale,HADS). I pazienti arruolati in questi anni di dottorato, rappresentanti il campione preliminare di uno studio assai più complesso e con una numerosità campionaria presunta molto superiore, sono stati 50 (33M e 17F) così suddivisi: - 23 (46%) pazienti arruolati nel braccio ketamina+propofol - 27 (54%) nel braccio remifentanil+propofol. A sua volta ciascun paziente è stato poi distinto in MEDICO, CHIRURGICO, TRAUMA, USTIONATO. Dall'analisi dei dati preliminari, è emerso che l'infusione continua di ketamina rappresenta una valida alternativa ai più comuni protocolli analgosedativi utilizzati nelle rianimazioni di tutto il mondo. La ketamina sembra avere capacità di mantenere un RASS target tra 0 e -2 (nei pazienti critici) sovrapponibile a remifentanil, con probabilità di eventi avversi pressoché identiche (circa 13% in entrambi i gruppi). Idem per quanto riguarda i dati che riguardano il dolore e il comfort paziente-ventilazione (valutazione realizzata tramite CCPOT). Buoni risultati sono stati ottenuti dall'uso dell'antagonista-NMDA nei pazienti con iniziale sostegno inotropo. Minor utilizzo di catecolamine ed instabilità emodinamica nei pazienti chirurgici, traumatizzati ed ustionati se trattati con ketamina vs remifentanil. Dati ancora incompleti sulle eventuali differenze di canalizzazione o tollerabilità alla nutrizione enterale tra i due protocolli. Per quanto riguarda i risultati sull'incidenza di delirium nei primi 3 giorni dopo l'estubazione, trend a favore dei pazienti trattati con ketamina (34% vs 44%) ma necessario approfondimento delle eventuali correlazioni con storia clinica, gravità, età, deficit cognitivo alla dimissione (MMSE) ed incidenza di ansia/depressione a lungo termine (HADS). Nello specifico per quanto riguarda il riscontro di delirium a breve termine, cioè entro i primi 3 giorni dopo l'estubazione, e alla dimissione dalla TI, ben 4 pazienti sono risultati positivi ad entrambi i test (2 per ketamina e 2 per remifentanil) ed avevano più di 65 anni. Per concludere tale risultato lascia presupporre una possibile correlazione tra insorgenza di delirium, età e declino cognitivo/funzionale nell'adulto.

Full textThe aim of this thesis is to determine how to create new transmission spectra of sunglasses that provide good rendering of natural colors. We investigate the appearance of color surfaces seen through color filters by characterizing the effect of the color filter through the color changes it induces. Color surfaces are manufactured coated samples and natural samples. Four procedures to investigate appearance are carried out and validated: in a real environment (light booth), a virtual environment (simulator), a natural environment and by mathematical modeling (color appearance model, CIECAM02). Psychophysical methods used are two-hue color naming and appearance judgment on semantic scales. An original method of denoising results by Fourier analysis is implemented. Optimum color filters are computed and a few are manufactured

Full textThe thesis tries to reconstruct, also through archival and bibliographical unpublished material, the figure of the blind sicilian intellectual Vincenzo Tedeschi Paternò Castello (1786-1858), philosopher and professor at the University of Catania. The structure of the thesis is divided into three chapters. The first is dedicated to an overview of the life and works of Vincenzo Tedeschi Paternò Castello Tedeschi, and also of the historical context in which he lived and worked. The second chapter analyzes the troubleds steps of his academic career, from the participation tu the Call for Chair of Physics, to the nomination as Professor of Metaphysics (an event in which blindness had an important role). In the third chapter, finally, we reconstruct the involvement of Tedeschi Paternò Castello in the political and administrative activity. The thesis ends with a reasoned Bibliography in which are also indicated sources and manuscripts (mostly unpublished, found in the State Archive of Catania and the Historical Archive of the University of Catania) and books and articles of Vincenzo Tedeschi Paternò Castello

"Impatto della supplementazione con Ubiquinolo sulla funzione endoteliale in soggetti a rischio di sviluppare patologie cardiovascolari: studio clinico spontaneo, in doppio cieco, randomizzato, controllato con placebo, a gruppi paralleli." Doctoral thesis, Università Politecnica delle Marche, 2018. http://hdl.handle.net/11566/252542.
Full textMost of the major cardiovascular risk factors are characterized by an increased production of reactive oxygen species (ROS), leading to endothelial dysfunction through breakdown of the vasodilating compound nitric oxide (NO). Supplementation with Coenzyme Q10 (CoQ10) positively affects heart performance in congestive heart failure and ischemic heart disease, along with a significant blood pressure lowering effect. To understand the effects of ubiquinol supplementation on endothelial function, measured through non-invasive ultrasonographic assessment of flow-mediated dilation (FMD), a double-blind, randomized, parallel-groups clinical trial was carried out on 51 subjects with moderate cardiovascular risk and endothelial dysfunction. Subjects were randomized to receive ubiquinol, 100 or 200 mg daily, or placebo. During each visit (T0, 4-weeks, 8-weeks) blood pressure, FMD, hematologic parameters (including lipid profile), reduced/oxidized CoQ10 levels, NO and peroxynitrite plasma levels were evaluated. Ubiquinol administration strongly improved total and reduced CoQ10 plasma levels. Subjects assigned to both treatment groups showed an increased FMD compared with subjects in placebo group, with no significant difference between the two dosages. However, after CoQ10 plasma bioavailability analysis, a positive relationship between FMD increases and CoQ10 oxidative status improvements was demonstrated. No significant change in lipid profile was observed in treated subjects. A significant dose-dependent increase in NO plasma levels was observed in treated subjects after T2. NO plasma levels are positively related to FMD and, thus, to endothelial function. FMD and plasma oxidative status are significantly improved following administration of ubiquinol. Bioavailability of ubiquinol is positively correlated with FMD improvements. Positive influence of CoQ10 supplementation is independent from plasma lipid profile, suggesting a direct effect of ubiquinol on endothelial cells.

Full textIntroduction: Cirrhosis is frequently complicated by the increase of portal pressure and development of esophageal varices, ascites and upper gastrointestinal bleeding. The mechanism of action of β-blockers in reducing the value of HVPG depends on a decreased portal inflow, secondary to the reduction of the index and to splanchnic vasoconstriction. Unfortunately, intrahepatic vascular resistance is poorly influenced by the action of beta-blockers. 5-methyltetrahydrofolate (5-MTHF) can improve vascular function through its action on eNOS and vascular oxidative stress Currently it is not known whether 5-MTHF may have the same effect on liver microcirculation. Objectives: to evaluate the efficacy of 3 months treatment with 5-MTHF in combination with propranolol compared to propranolol + placebo in terms of reduction of HVPG in cirrhotic patients with portal hypertension (PI). Secondary objectives are: a) to evaluate the tolerability of 5-MTHF in cirrhotic patients with PI; b) to evaluate if there is an improvement in the intrahepatic vascular tone mediated by the decrease of oxidative stress because of greater bioavailability of NO in patients with cirrhosis and PI. Results: in both groups there was a reduction in the HVPG value compared to baseline, but the change was significantly higher in the 5-MTHF group compared to the placebo group (20.8%, SD 15.4 in the 5-MTHF vs 9.2%, SD 21.3 in the placebo group, p=0.033). A similar reduction was noted for the value of elastometry measured with FibroScan® (21.8%, SD 34.7 in the 5-MTHF group vs. 4.4%, SD 32.5 in the placebo group, p = 0.064). Discussion: the comparison analysis between the treatment group and the placebo group shows a statistically significant difference in terms of reduction of porto-systemic pressure gradient. Further multi-center studies on larger cohorts are desirable to validate the use of 5-MTHF + placebo in reducing the portal pressure value measured with HVPG

Full textThe thesis "Dynamics of liquids in confinement - the application of Nuclear Magnetic Resonance Relaxometry" describes in detail the analysis and interpretation of the spin-lattice relaxation rate dispersion of ionogels based on two ionic liquids: l-ethyl-3-methyIimidazolium thiocyanate ([EMIM][SCN]) and I-butyl-3-methylimidazolium octyl sulphate ([BMIM][0 cS0 4 ]).The ionogel is a solid system within which the ionic liquid has been immobilized. Thanks to such solidification, they can be used in a safer way as electrolytes in electronic devices, batteries, etc. From the applicational point of view, it is important to know how the confinement affects the liquid dynamics and, indirectly, the ionic conductivity of the final product. The technique used for the research was Fast Field Cycling Nuclear Magnetic Resonance (FFC NMR) Relaxometry. This is a unique experimental method that allows to identify the mechanisms and time scale of dynamic processes in molecular and ionic systems, both solid and liquid. Observation of 1H nuclear relaxation of ionic liquids in free state (bulk liquid) and in confinement (liquid entrapped in silica matrices) revealed changes in molecular dynamics depending on the type of ionic liquid and its relative content within the pores of the matrix. Analysis of 1H NMR spinlattice relaxation rate dispersion profiles in broad Larmor frequency range (4 kHz - 40 MHz) and temperature range (223 - 253 K for [EMIM][SCN] and 243 - 303 K for [BMIM][0 cS0 4 ]) allowed to distinguish and characterize different mechanisms of ion diffusion taking place in different timescales. An in-depth analysis of the frequency dependence of spin-lattice relaxation rate was based on the model with the total relaxation rate decomposed into contributions that stem from the fluctuation of the dipole-dipole interactions modulated by the translational and rotational dynamics of the ions. Due to different functional dependence on the Larmor frequency, these contributions can be separated and the correlation times characterizing the given process can be determined. Parameters describing the translational and rotational diffusion processes obtained for liquids in a free form were used as a reference point to describe the dynamics of ions altered due to geometric confinement. Two main fractions of the ionic liquid were distinguished: first one located in the center of the pore, the dynamics of which was similar to the dynamics of the pure liquid, and the fraction of liquid closer to the surface of the silica matrix. Correlation times and relative diffusion coefficients have been determined, as well as their temperature dependence according to the Vogel-Fulcher-Tammann relationship. One of the most important conclusions of the work is that despite the interaction with the silica surface and the steric effects, the translational dynamics for all studied systems retains its three-dimensional character.
