Selenium adsorption on Mo(110): A first-principles investigation
2013
Selenium adsorption on molybdenum surfaces is a relevant process in the production of thin-film solar cells, in particular as far as the formation of the layered compound MoSe${}_{2}$ is concerned. In this paper we investigate the energetics of Se adsorption on the (110) surface of molybdenum using first-principles calculations in the two limiting cases of low and high coverage, and we establish a comparison with the more extensively investigated case of sulfur adsorption at submonolayer coverage. The studied system provides the opportunity for testing the most crucial approximations, namely, the choice of the exchange-correlation functional and the pseudopotential generation. We find that …
Effectiveness of an educational intervention on seasonal influenza vaccination campaign adherence among healthcare workers of the Palermo University …
2018
Introduction. Healthcare workers are continuously exposed to the risk of being infected by influenza viruses during their work, thus representing a threat especially for fragile patients. Although the Italian Ministry of Health strongly recommends influenza vaccination for all HCWs, coverage levels in Italy are still far from the expected. Several studies report that one of the preferred strategies to improve vaccination coverage among Healthcare Workers is improving vaccination knowledge through specific multidisciplinary courses. To assess the effectiveness of an educational intervention on influenza vaccination coverage among Healthcare Workers a study was conducted at "Paolo Giaccone" U…
Prove di controllo di Ceratitis capitata (Wiedemann) in pescheti, aranceti e clementineti biologici
2011
Tests to control Ceratitis capitata (Wiedemann) in organic peach, orange and clementine orchards. The Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann), is considered the key pest of several fruit species in organic farming. Experiments for the control of this pest have been carried out in organic peach orchards (in 2009 on a medium-late ripening cultivar, ‘Bella di Bivona’; in 2011 on a very early ripening one, ‘San Pedro’) testing nets, spinosad and pyrethrum (year 2009), in orange citrus groves (cv. Navelina, early ripening period), comparing spinosad, kaolin and bentonite (years 2009 and 2010) and in a clementine grove (cv. Monreal), using kaolin and bentonite. The very early ripe…
Can influenza vaccination coverage among healthcare workers influence the risk of nosocomial influenza-like illness in hospitalized patients?
2013
Background Approximately 20% of healthcare workers are infected with influenza each year, causing nosocomial outbreaks and staff shortages. Despite influenza vaccination of healthcare workers representing the most effective preventive strategy, coverage remains low. Aim To analyse the risk of nosocomial influenza-like illness (NILI) among patients admitted to an acute care hospital in relation to influenza vaccination coverage among healthcare workers. Methods Data collected over seven consecutive influenza seasons (2005–2012) in an Italian acute care hospital were analysed retrospectively. Three different sources of data were used: hospital discharge records; influenza vaccination coverage…
The impact of media and NGOs on four European Parliament discourses about conflicts in the Middle East
2017
There is empirical evidence of media influence on parliamentary agenda, especially when media coverage privileges conflict framing of reality and negativity. This article addresses the impact of me...
Shear bond strength of partial coverage restorations to dentin
2015
BACKGROUND: When partial coverage restorations (veneers, inlays, onlays…) must be cemented to dentin, bond strength may not reach the same predictable values as to enamel. The purpose of this study was: 1. To compare, with a shear bond test, the bond strength to dentin of a total-etch and a self-etching bonding agent. 2. To determine whether creating microretention improves the bond strength to dentin. MATERIAL AND METHODS: Two bonding agents were assayed, Optibond FL® (Kerr), two-bottle adhesive requiring acid etching, and Clearfil SE Bond® (Kuraray), two-bottle self-etching adhesive. The vestibular, lingual, distal and mesial surfaces of ten molars (n=10) were ground to remove all enamel …
Assessment of non-carious root surface defects in areas of gingival recession: A descriptive study.
2015
BACKGROUND The purpose of this descriptive study was to observe the distribution of four different classes of non-carious cervical root surface discrepancies in teeth with gingival recession. Additionally to explore the different treatment modalities in the literature for each of these defects. MATERIAL AND METHODS A total of 150 subjects with at least one labial gingival recession were included in the study. 1400 teeth were evaluated using 2.5 X magnification loupes and UNC -15 probe for the presence of the cemento-enamel junction and step like defects according to Pini-Prato's classification: A-, identifiable CEJ without defect; A+, identifiable CEJ with defect; B-, unidentifiable CEJ wit…
Third molar autotransplant planning with a tooth replica. A year of follow-up case report
2021
The advantages of dental autotransplantation and its high level of clinical success mean that it should be considered as a therapeutic option when replacing a lost tooth. In order to achieve optimum results, it is necessary to know the technique of dental autotransplantation, promoting its use whenever the clinical conditions to perform it are present. The objective of this article is to describe the technique in detail by means of a clinical case of a dental autotransplant whose donor tooth was a third unerupted molar. A 39-year-old male patient with no medical history of interest. On clinical examination, tooth 2.6 shows vertical fracture with indication of exodontia. A compatibility stud…
La información sobre la monarquía española en los nuevos medios digitales: ElDiario.es y VozPópuli.com
2013
Los contenidos mediáticos relativos a la Familia Real española han estado tradicionalmente restringidos a un tratamiento muy respetuoso, positivo, y complaciente. Esta tendencia, como es notorio, ha cambiado vertiginosamente en los últimos meses, por efecto de una serie de informaciones negativas que afectan a distintos miembros de la Casa Real, a su vez potenciadas por la grave crisis económica que afecta al país y por la acción de nuevos medios y espacios de comunicación desarrollados en Internet. El objetivo del presente estudio es analizar las informaciones periodísticas publicadas en dos nuevos medios digitales, Eldiario.es y Vozpopuli.com, referidas a la Monarquía, con el propósito de…
Seawater carbonate chemistry and biogenic habitat shifts under long-term ocean acidification
2023
Experiments have shown that increasing dissolved CO2 concentrations (i.e. Ocean Acidification, OA) in marine ecosystems may act as nutrient for primary producers (e.g. fleshy algae) or a stressor for calcifying species (e.g., coralline algae, corals, molluscs). For the first time, rapid habitat dominance shifts and altered competitive replacement from a reef-forming to a non-reef-forming biogenic habitat were documented over one-year exposure to low pH/high CO2 through a transplant experiment off Vulcano Island CO2 seeps (NE Sicily, Italy). Ocean acidification decreased vermetid reefs complexity via a reduction in the reef-building species density, boosted canopy macroalgae and led to chang…
