Rotational CARS thermometry at high temperature (1800 K) and high pressure (0.1-1.55 MPa)
2007
International audience; Dual-broadband rotational CARS (DB-RCARS) thermometry has been investigated at high temperature and high pressure. Single-shot measurements were performed at 1800 K, in air and nitrogen at pressures up to 1.55 MPa and in oxygen at pressures up to 0.5 MPa. For all conditions, the resonant signal contribution to the spectra clearly dominated over the non-resonant one, implying the high potential for DB-RCARS for temperature and concentration measurements also at the high temperatures and pressures used in the present investigation. The relative standard deviation was generally similar to 2% for single-shot data at pressures from 0.5 to 1.55 MPa. At the investigated tem…
Verifiche Diagnostiche nell'ex Chiesa Madre di Santa Margherita di Belice
2011
La relazione presenta in modo dettagliato gli esiti della seconda campagna di indagini diagnostiche, svolta nella fabbrica architettonica a cantiere di restauro in corso d'opera. L'obiettivo delle valutazioni non distruttive e minimamente invasive è valutare la corretta esecuzione degli interventi attraverso il confronto tra la diagnosi preliminare e quella post-intervento. The report presents in detail the results of the second campaign of diagnostic investigations, carried out in the architectural restoration site. The goal of minimally invasive and non-destructive evaluation is to assess the proper execution of consolidation through the comparison between the preliminary and post-interve…
Sistema integrato di metodiche diagnostiche per il restauro della chiesa di Sant’Anna La Misericordia a Palermo
2010
E' mostrata l'applicazione di un sistema combinato di letture strumentali finalizzate all'ottenimento di una diagnosi attraverso un approccio dall'elevato rigore scientifico. Le analisi strumentali sono svolte nella chiesa di Sant'Anna a Palermo. The graphs show the application of a combined system of instrumental readings aimed to obtain a diagnosis through a high scientific and rigorous approach.

DIAGNOSIS FOR ARCHITECTURAL CONSERVATION. A synthetic report of a campaign of non-destructive and minimally invasive diagnostic tests performed in th…
2014
The paper presents the results of a campaign of non-destructive and minimally invasive tests that were conducted in the church of Santa Maria delle Stelle in Comiso (Ragusa, Sicily), which is the larger church in the Diocese of Ragusa. It includes a summary of the reflections that arose during the preliminary surveys and instrumental tests, and reasons that supported the choice of investigations to be performed and methods to be specifically applied for the consolidation of the architectural structures and plaster layers.
THE ROLE OF THERMOGRAPHY IN THE NON-DESTRUCTIVE EVALUATION OF HISTORICAL ARCHITECTURAL SURFACES. Some observation about the method and its purpose
2014
Infrared-Thermography (IRT) has become a supporting tool for the investigation of historical structures and facades. Using the non-destructive testing method for the detection can give a profound knowledge about the current status of the object and the state of decay, about different kinds of discontinuities at historical facades, of construction details and of thermal bridges in the facades. Different case studies of thermographic surveys on some Sicilian monuments are presented and discussed to illustrate how the method can offer applicable information about the investigated objects and demonstrate its reasonable integration into conservation projects.

Salivary inflammatory proteins in patients with oral potentially malignant disorders
2019
Cytokines are a group of small proteins involved in the regulation of infection, immune responses and inflammation. Since altered cytokine responsiveness has been linked to Oral Squamous Cell Carcinoma (OSCC), research to date indicates the possibility of using salivary pro- and anti-inflammatory proteins for screening of oral disorders. OSCC is a multistep neoplasia in which many genetic and epigenetic changes have been correlated to cancerous transformation of oral potentially malignant disorders (OPMD) such as oral leukoplakia, erythroplakia and lichen planus. The goal of the innovative salivary diagnostics is the identification of a single or multiple biomarkers that will serve as a cli…
Skin cancer screening – better safe than sorry
2020
Skin cancer is the most common type of cancers. In Latvia, on average there are approximately 200 new melanoma and 1300 non-melanoma cancer cases per year. Non-melanoma cancers are: Basal Cell Carcinoma, Squamous Cell Carcinoma and others. It is essential to discover skin cancer at an early stage when it is treatable. For this reason, a reliable, non-invasive and quantitative skin cancer screening method is necessary in order to discover skin cancer as early as possible and to help physicians such as general practitioners and dermatologists assign patients to the best treatment as soon as possible. In this article, the current skin cancer incidence as well as the screening situation in Latv…
