Topical Fluoride for Preventing Dental Caries in Children and Adolescents
2012
The use of topically applied fluoride has been widely researched as a means to reduce the risk of dental caries in conjunction with other treatment modalities (mechanical oral hygiene, dietary control, antimicrobial intervention, pit and fissure sealants). There is overwhelming evidence that reports not only the significance and importance of the use of fluoride as a caries-preventive agent, but also how safe fluoride application is when used appropriately, particularly in higher risk individuals and populations. This paper reviews the caries-protective benefits of topical fluoride application in children and adolescents, with an emphasis on the clinical efficacy and safety of the vehicles …
Low-Cost Sensor Based on SDR Platforms for TETRA Signals Monitoring
2021
The paper presents the design and implementation of an electromagnetic field monitoring sensor for the measurement of the Terrestrial Truncked Radio (TETRA) signals using low-cost software defined radio (SDR) platforms. The sensor includes: an SDR platform, a Global Positioning System (GPS) module and a hardware control module. Several SDR platforms having different resolutions of the analog–digital converters were tested in the first phase. The control module was implemented in two variants: a fixed one, using a laptop, and a mobile one, using a Raspberry Pi. The tests demonstrate the following achieved performances: instantaneous acquisition band of 5.12 MHz
Experimental analysis of "bovedas tabicadas"
2012
A particular type of vaulted structures, known as bóvedas tabicadas (Catalan vaults), made with alternate layers of bricks and mortar and characterized by a very low thickness in comparison to the other two dimensions, are studied. The research has been faced under the historical aspect as well as under the mechanical one, developing experimental and numerical analysis regarding real existing structures. In particular, the experimental analysis, performed by effecting compression and bending tests on samples taken from a real structure, has been devoted to the constitutive material identification and the characterization is made by considering the material as an ideal homogeneous; further e…
Economic Robustness Analysis of Adaptive Chart Schemes for Monitoring the Total Nonconformities Number in Inspection Units
2015
In recent years, a variety of enhanced schemes for the c chart have been developed aimed at the effectiveness improving of the related statistical process control (SPC) procedures. However, the performance of such chart schemes can be very sensitive to values assumed for some operating and cost parameters, in particular to the considered process shift magnitude arising from out-of-control conditions. In such a circumstance, the effectiveness of such chart schemes can be subjected to substantial reductions when they are implemented in operative contexts given that, in practice, such value is unknown and it can be very difficult to accurately estimate. For this reason, in the present paper i…

Efectos de la auditoría sobre la credibilidad y la calidad de la información contable de las pymes
2014
La presente tesis doctoral examina dos objetivos básicos: i) si la auditoría contribuye a la reducción del coste de financiación de las pymes, por la credibilidad que ésta otorga a la información contable; y ii) si, con independencia de la credibilidad que le otorga la auditoría, la información contable es de mayor calidad. Las motivaciones para este análisis surgen por la relación mostrada en la literatura previa entre el coste de financiación y la calidad de la información contable. En este sentido, la auditoría, como actividad consistente en la revisión de la información financiera, desempeña un papel muy relevante en un doble sentido: i) como instrumento que contribuye a la calidad de l…
The role of patient specific morphology and contractility of the left atrial appendage on the thromboembolic risk in atrial fibrillation
2022
The vast majority of thrombi that cause ischemic complications in atrial fibrillation originate in the left atrial appendage. The left atrial appendage is an anatomical structure that starts from the left atrium, characterized by a wide morphological variability between individuals. This work analyses simulated hemodynamic for different patient-specific models of the left atrial appendage, using computational fluid-structure interaction studies, modelling the effect of changes in contractility and shape resulting from atrial fibrillation. Three operating conditions were analysed: sinus rhythm, acute atrial fibrillation, and chronic atrial fibrillation. These were simulated on four patient-s…
PREVALENCE OF ARTERIAL HYPERTENSION AND CHARACTERISTICS OF NOCTURNAL BLOOD PRESSURE PROFILE OF ASTHMA PATIENTS ACCORDING TO THERAPY AND SEVERITY OF T…
2020
Background: several studies report an increased risk for asthmatic subjects to develop arterial hypertension and the relationship between these two diseases, frequently co-existing, still has some unclear aspects. Methods: The BADA (blood pressure levels, clinical features and markers of subclinical cardiovascular damage of asthma patients) study is aimed to evaluate the prevalence of the cardiovascular comorbidities of asthma and their impact on the clinical outcome. The main exclusion criteria were the presence of other respiratory diseases, current smoking, any contraindication to ambulatory blood pressure monitoring (ABPM). Results: The overall percentage of asthmatics having also hyper…
Carta dei diritti fondamentali dell’Unione europea tra controllo accentrato di legittimità costituzionale e disapplicazione: la Corte di giustizia di…
2014
Con la sentenza A c. B e altri (CGUE 11 settembre 2014 C-112-13) la Corte di giustizia si è pronunciata sulla compatibilità con il diritto dell’Unione dei meccanismi procedurali, vigenti in Austria, volti a risolvere le antinomie tra fonti interne e diritti garantiti dalla Carta dei diritti fondamentali dell’Unione europea. Il problema, in particolare, si è posto per via di una recente sentenza del Verfassungsgerichtshof (Tribunale costituzionale federale austriaco, in prosieguo “VFGH”), nella quale si afferma che la Carta dei diritti fondamentali integra il parametro nazionale di costituzionalità. In un contesto, come quello austriaco, nel quale vige un sistema di controllo accentrato di l…
