An empirical test of neighbourhood effect and safe-site effect in abandoned Mediterranean vineyards
2011
The importance of both neighbourhood effect and safe-site effect for the colonization of Mediterranean old fields by woody plants was investigated. Using a transect approach, we recorded colonization of 21 species of woody plants on abandoned, terraced vineyards on Pantelleria Island (Sicily) in dependence from neighbouring terraces in older succession stages (Maquis) and available safe sites for seedling establishment (former crop plant, terrace wall). With a paired design of four treatments, including presence/absence of adjacent older successional stages, and North-/South-facing slopes, a neighbourhood effect could be shown for both expositions if the transect started from an adjacent fi…
A chronosequence study of vegetation dynamics on vine and caper terraces of Pantelleria Island (Sicily)
2006
The vegetation of fallow fields of different age in the terraced agricultural landscape of Pantelleria Island (Sicily) was analysed via vegetation relevés. Five age classes in N-facing as well as in S-facing slopes of both vine and caper fallows were differentiated. The main questions were to determine the sequence of plant communities in time and to test some environmental factors for their influence on the course and the speed of succession. The results show that undisturbed abandoned terraces are subject to rapid renaturation: 50 to 80 years old fallows are now covered by dense maquis communities. Both N- and S-facing slopes seem to converge to a Quercus ilex woodland as the climax commu…
Detection of Candidatus Neoehrlichia mikurensis in Norway up to the northern limit of Ixodes ricinus distribution using a novel real time PCR test ta…

Background Candidatus Neoehrlichia mikurensis is an emerging tick-borne pathogen. It is widely distributed in Ixodes ricinus ticks in Europe, but knowledge of its distribution in Norway, where I. ricinus reaches its northern limit, is limited. In this study we have developed a real time PCR test for Ca. N. mikurensis and used it to invest…
Drug Resistance in Salmonella enterica ser. Typhimurium Bloodstream Infection, Malawi
2014
To the Editor: Salmonella enterica serotype Typhimurium is one of the most common causes of bloodstream infection in sub-Saharan Africa (1). Among adults, the principal risk factor for invasive nontyphoidal Salmonella (iNTS) disease is advanced HIV infection; up to 44% of HIV-infected patients experience bacteremic recurrence through recrudescence of the original infection (2,3). Epidemics of iNTS disease in sub-Saharan Africa have been associated with a novel genotype of S. enterica ser. Typhimurium of multilocus sequence type (ST) 313 that is rarely seen outside the region and is associated with multidrug resistance (MDR) to chloramphenicol, cotrimoxazole, and ampicillin (4,5). As a conse…
Il ruolo delle amministrazioni coinvolte nel passaggio diretto di personale
2022
Il contributo, a partire dall’inquadramento della natura dell’istituto della mobilità individuale volontaria di cui all’art. 30 D. Lgs. n. 165/2001, mette in evidenza i compiti delle amministrazioni coinvolte nella procedura del passaggio diretto di personale e i limiti alla loro discrezionalità. Ciò implica alcune inevitabili considerazioni sugli effetti dei più recenti interventi di riforma in materia, in particolare ad opera del cosiddetto “Decreto Reclutamento”. Starting from the framework of the nature of the institution of individual voluntary mobility under the article 30 of Legislative Decree No. 165/2001, this paper highlights the tasks and discretionary powers of the administratio…
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…
Prevalence of Dentine Hypersensitivity in a General Dental Practice in Greece
2011
Objectives: The aim of this study was to estimate the prevalence of dentine hypersensitivity in a sample of patients visiting a general dental practice. Study design: The study population consisted of 1,450 patients, 690 males and 760 females, aged 18-69 years. All individuals were clinically examined and answered questions regarding variables such as gender, age, educational level, occupation status, teeth affected and any factor that initiated the sensitivity. The clinical examination involved assessment of sensitive teeth per patient, while the amount of buccal gingival recession associated with the sensitive teeth was also recorded. Statistical analysis performed by using methods of des…
Prospective study of monolithic zirconia crowns: clinical behavior and survival rate at a 5-year follow-up
2020
Purpose To evaluate the clinical behavior and survival of full coverage monolithic zirconia crowns on posterior teeth over a 5-year follow-up. Methods Fifty patients were recruited and underwent restoration with a Lava Plus monolithic zirconia crown (Lava™ Frame Zirconia, 3M Espe, Germany) on premolars or molars. Patients were monitored over a 5-year follow-up (2014-19), recording any biological and/or mechanical complications; these data were used to estimate the crowns' success rate. Periodontal clinical parameters were recorded (pocket probing depth (PPD), plaque index (PLI), bleeding on probing (BOP), and gingival recession (GR)). Wear to the zirconia crowns and antagonist teeth were al…
la noblesse dans la monarchie espagnole des Habsbourg aux Bourbons. Langages et pratiques de fidélités anciennes et nouvelles
2018
Lo scopo del saggio è di offrire una riflessione sulla nobiltà spagnola, siciliana e napoletana nel complesso quadro della crisi dinastica verificatasi nella monarchia spagnola alla morte di Carlo II. A partire dall'analisi delle dinamiche che hanno iniziato a modificare il ruolo delle Grandes alla corte di Madrid durante la reggenza di Mariana de Austria, l'attenzione si concentra principalmente sui decenni tra la fine del XVII e l'inizio del XVIII secolo. La ricerca evidenzia strategie personali e legali, nuove pratiche e linguaggi di negoziazione tra nobiltà e sovrano, al fine di comprendere le motivazioni che hanno costituito la base per l'adesione della nobiltà mediterranea al partito …
Avoiding patterns in irreducible permutations
2016
We explore the classical pattern avoidance question in the case of irreducible permutations, <i>i.e.</i>, those in which there is no index $i$ such that $\sigma (i+1) - \sigma (i)=1$. The problem is addressed completely in the case of avoiding one or two patterns of length three, and several well known sequences are encountered in the process, such as Catalan, Motzkin, Fibonacci, Tribonacci, Padovan and Binary numbers. Also, we present constructive bijections between the set of Motzkin paths of length $n-1$ and the sets of irreducible permutations of length $n$ (respectively fixed point free irreducible involutions of length $2n$) avoiding a pattern $\alpha$ for $\alpha \in \{13…
