Recuperare e conservare. il complesso San Pancrazio a Taormina
2015
Il Complesso denominato di San Pancrazio si trova nel centro storico di Taormina, è di proprietà privata ed è costituito da una Domus ellenistico-romana con peristilio rettangolare, da una Villa costruita in periodo liberty e da un piccolo parco che presenta significativi elementi di arredo. Con approccio congiunto tra discipline diverse e sulla scorta degli obiettivi di ricerca del Dottorato in Recupero e Fruizione dei Contesti Antichi, attivato dal 1990 all’Università degli Studi di Palermo, l’intervento propone il recupero, la conservazione, la messa in valore e la musealizzazione delle due costruzioni antiche e dell’area circostante. Così, dopo un profilo storico-topografico e il riliev…
The role, the goal and the soul of professional public relations : developing a holistic model of PR professionalism
2016
This doctoral dissertation investigates PR professionalism and PR as a strategic expert function. The approach is phenomenographic and the research progresses through four phases: (1) building a conceptual framework, (2) conducting an interpretative study of concepts, (3) conducting semi-structured in-depth interviews among 37 Finnish PR experts, and (4) constructing a holistic model of PR professionalism. The interpretative study of concepts concludes that PR professionalism consists of expertise in management of identity, management of public sphere, and management of relationships, and its core values are respect, responsibility and reflexivity. The interview study outlines five differen…
Four-dimensional representation of scattering amplitudes and physical observables through the application of the Loop-Tree Duality theorem
2019
Las últimas dos décadas han sido testigo de un tremendo progreso en la física teórica de alta precisión. Muchos avances han sido hechos, en particular, en la evaluación de diagramas multi-loop, pero el principal desafío yace en el tratamiento de las divergencias IR a través de eficientes esquemas de substracción. Con la complejidad del procedimiento incrementándose exponencialmente con el número de escalas, se ha hecho necesario tratar la cuestión desde un ángulo diferente, invocando así al desarrollo de nuevas técnicas. La Dualidad Lazo-Árbol (LTD, por sus siglas en inglés) provee de un nuevo marco para el cómputo de amplitudes con loops. A través de la modificación de la prescripción está…
FRP reinforcement for concrete structures: state-of-the-art review of application and design
2014
Fiber reinforced polymers (FRPs) are considered to be a promising alternative to steel reinforcement, especially in concrete structures subjected to an aggressive environment or to the effects of electromagnetic fields. Although attempts to develop effective reinforcement have been followed, the application of FRPs remains limited by the solution to simple structural problems that mainly appear due to the absence of design codes, significant variation in the material properties of FRP composites and limited knowledge gained by engineers as regards the application aspects of FRP composites and structural mechanics of concrete elements reinforced with FRPs. To fill the latter gap, the current…
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
HYPERBLEND: SIMULATING SPECTRAL REFLECTANCE AND TRANSMITTANCE OF LEAF TISSUE WITH BLENDER
2022
Abstract. Remotely sensing vegetation condition and health hazards requires modeling the connection of plants’ biophysical and biochemical parameters to their spectral response. Even though many models exist already, the field suffers from lack of access to program code. In this study, we will assess the feasibility of open-source 3D-modeling and rendering software Blender in simulating hyperspectral reflectance and transmittance of leaf tissue to serve as a base for a more advanced large-scale simulator. This is the first phase of a larger HyperBlend project, which will provide a fully open-source, canopy scale leaf optical properties model for simulating remotely sensed hyperspectral imag…
Medium-term effects of bisoprolol administration on renal hemodynamics and function in mild to moderate essential hypertension
2007
Arterial hypertension is a significant cause of end-stage renal failure; effective treatment of hypertensive patients reduces the rate of progression of this disorder. ss-Blockers, particularly nonselective agents, are associated with deterioration of renal function in patients with chronic renal failure. Previous studies on the interaction of the beta1-selective adrenergic antagonist bisoprolol with kidney function have been performed only acutely and over the short term. This study was designed to evaluate the antihypertensive efficacy and effects on renal hemodynamics and function of bisoprolol during medium-term (6 mo) treatment of patients with mild to moderate essential hypertension. …

La incorporación de las preferencias musicales de los estudiantes como aproximación a una educación crítica. Análisis curricular y desarrollo didácti…
2021
Una de las finalidades planteadas por la educación formal es que los estudiantes, además de alcanzar una adecuada formación académica, adquieran una competencia cívica y democrática que les permita desarrollarse como ciudadanos críticos dentro de su contemporaneidad. Entre las dimensiones educativas que entran en juego desde esta perspectiva, destacan el reconocimiento de sus identidades culturales, la participación en el diseño curricular y la construcción de un pensamiento crítico que incorpore una base ética. En este sentido, el objetivo de esta tesis es el de contribuir al desarrollo de un enfoque crítico en educación musical primaria mediante la utilización de un repertorio musical que…
