The use of a European coinage alloy to compare the detection limits of mobile XRF systems. A feasibility study
2007
The investigation of archaeological and historical materials makes use of techniques that, though borrowed from other fields of research and industrial production, frequently have to be 're-invented' because of peculiar characteristics of the analysed objects. Artistic relevance, limited movability, compositional and structural heterogeneity radically change the experimental approach and often require ad hoc designed equipment. These considerations also apply to x-ray fluorescence, especially regarding mobile systems. The extensive development and use of mobile spectrometers has produced an extremely diversified context and created the need for common criteria to evaluate their performances…
COVID-19, A new challenge in the dental practice
2021
Background This review was conducted in order to learn the latest information about how to prevent cross-infection of COVID-19 in dentistry. The aim of this study is offer a clinical protocol to reduce the risk of infection of COVID-19 in dental settings. Material and methods We carried out a review based on the PRISMA guide (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We used the following three databases: PubMed, Embase and Scopus. The search strategy was performed in the three databases applying the search terms "COVID-19 AND dental", "COVID-19 AND dentistry", selecting human studies published from November 2019 to May 2020. English publications regarding COVID-1…
Mise en évidence de corps d'origine cosmique probable au sein de la formation de Carnot (République Centrafricaine)
1992
Resume Deux etudes realisees independamment l'une de l'autre, ont permis de mettre en evidence, au sein de la Formation de Carnot, formation fluviatile mesozoique, d'une part des spherules magnetiques recuperees dans les residus d'un forage (zone de Boyali), d'autre part une anomalie magnetique tres localisee (sur 270 metres de long) traduisant la presence d'un corps decametrique a forte magnetisation remanente (zone de Gambondo). Ces deux elements magnetiques ont une origine cosmique probable. Ils correspondent a des micrometeorites et a une meteorite ayant atteint l'ouest de la Republique Centrafricaine entre l'Albien et le Maastrichtien.

Evaluación criterial: determinación de estándares de interpretación (EE) para pruebas de rendimiento educativo
2009
En este trabajo se presenta una revisión del estado de la cuestión acerca de los métodos para determinar estándares en pruebas de referencia criterial. Se analiza el concepto de estándar, sus componentes y los problemas implicados en las tareas de juicio en estos métodos. Se revisan los procedimientos para diseñar descriptores de estándares y los métodos para identificar puntuaciones de corte.
The concept of major depression. I. Descriptive comparison of six competing operational definitions including ICD-10 and DSM-III-R.
1991
All operationalized diagnostic systems contain a diagnostic category, which corresponds to the concept of major depression. Yet, these corresponding definitions are not identical. Up to now, no comprehensive comparisons of the competing diagnoses have been published. We will therefore present a series of studies, describing six different operational definitions of major depression according to their content and construction and empirically comparing them in large inpatient and outpatient samples. This first paper presents a descriptive comparison of the definitions given in the Feighner Diagnostic Criteria, the Research Diagnostic Criteria, the Diagnostic and Statistical Manual of Mental Di…
Systematic review and critical appraisal of Childhood Trauma Questionnaire - Short Form (CTQ-SF).
2021
Abstract Background Child maltreatment is a complex and multidimensional construct that encompasses a great number of risk factors. The Childhood Trauma Questionnaire — Short Form, one of the most widely used and validated instruments to assess childhood maltreatment in the past ten years, is a retrospective instrument that assesses several types of childhood abuse and maltreatment which is divided into five dimensions. Objective The objectives of this systematic review are to critically appraise, compare, and summarize the methodological quality and psychometric properties of published research articles validating the Childhood Trauma Questionnaire — Short Form utilizing the COSMIN checkli…
Phytochemical Studies on Ptilostemon greuteri Raimondo & Domina (Compositae)
2012
Ptilostemon greuteri Raimondo & Domina is described as a new species and its growth is limited to the area of the province of Trapani. Essential oils of aerial parts of P. greuteri were analized by gas chromatography-mass spectrometry (GC-MS). The analysis of acetonic extract of aerial parts led to identification of triterpenes components: α-amyrin, β-amyrin, α-amyrin acetate, β-amyrin acetate, lupeol, lupeol acetate and taraxasterol. CC and preparative TLC of acetonic extracts has yielded lignan lactone and a sesquiterpene lactone that have been isolated previously from other Ptilostemon species.
Supporting public decision process in buildings energy retrofitting operations: the application of a Multiple Criteria Decision Aiding model to a cas…
2020
Abstract The challenge of promoting sustainable cities and reaching the objectives developed by the European Green Deal includes the renovation of the building sector, as it is responsible for 40% of energy consumption in Europe. Regional or local public administrations have to allocate their financial resources for improving the energy performances of their building stock and to face a multidimensional problem, where different aspects – such as energy efficiency, financial-economic feasibility and environmental protection – have to be harmonized. The present study proposes a Multiple Criteria Decision Aiding model, which includes the ELECTRE TRI-nC method, for supporting the public decisio…
