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…
Relative reproductive success of co-infecting parasite genotypes under intensified within-host competition.
2015
In nature, host individuals are commonly simultaneously infected with more than one genotype of the same parasite species. These co-infecting parasites often interact, which can affect their fitness and shape host-parasite ecology and evolution. Many of such interactions take place through competition for limited host resources. Therefore, variation in ecological factors modifying the host resource level could be important in determining the intensity of competition and the outcome of co-infections. We tested this hypothesis by measuring the relative reproductive success of co-infecting genotypes of the trematode parasite Diplostomum pseudospathaceum in its snail host Lymnaea stagnalis whil…
Traditional endodontic surgery versus modern technique: a 5-year controlled clinical trial.
2014
In this study, we compared outcomes of traditional apicoectomy versus modern apicoectomy, by means of a controlled clinical trial with a 5-year follow-up. The study investigated 938 teeth in 843 patients. On the basis of the procedure performed, the teeth were grouped in 3 groups. Differences between the groups were the method of osteotomy (type of instruments used), type of preparation of retrograde cavity (different apicoectomy angles and instruments used for root-end preparation), and root-end filling material used (gray mineral trioxide aggregate or silver amalgam). Outcome (tooth healing) was estimated after 1 and 5 years, postoperatively. Clinical success rates after 1 year were 67% (…
Infanticide in the evolution of reproductive synchrony: effects on reproductive success.
2007
Synchronous breeding in animals and plants has stimulated both a theoretical and empirical examination of the possible benefits of active synchronization. The selective pressures of predation and infanticide are the strongest candidates proposed to explain the evolution of reproductive synchrony. Alternatively, breeding asynchronously with conspecifics may ensure a greater availability of resources per breeder. However, the possible fitness benefits resulting from active asynchronization have not yet received attention in evolutionary ecology. Here we present a hypothesis, based on a graphical model, illustrating the costs and benefits of the two modes of reproduction. We tested the hypothe…
Effect of LASER therapy Vs conventional techniques on clinical and radiographic outcomes of deciduous molar pulpotomy : a systematic review and meta-…
2020
Background To systematically review the effectiveness primary molar pulpotomy based on the clinical and radiographic outcomes using lasers over the conventional therapies. Material and methods This systematic review and meta-analysis included Randomized or Quasi-randomized trials comparing LASER with conventional pulpotomy therapies (formocresol, ferric sulphate, MTA or calcium hydroxide) with atleast 6-month follow-up period was included. Risk of bias of included studies was assessed and metanalysis was done using RevMan software. Results Of the 1383 articles that were searched, only 14 studies were included for qualitative synthesis and 10 for meta- analysis. There was no statistically si…
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 …
La Guerra de Successió i el bloqueig de Dénia del 1705
2007
Perez Aparicio, Carmen - Carmen.Perez@uv.es Dénia va ser la primera població de la Corona d’Aragó a proclamar rei l’arxiduc Carles. Ho va fer sense que s’haguera produït cap desembarcament de tropes aliades, amb l’impuls dels mateixos valencians. Aquest treball estudia l’operació que va posar en marxa el govern borbònic per tal de recuperar-la; una empresa que es considerava fàcil, però que va esdevindre impossible per la mancança de tropes i d’artilleria per a posar un setge formal. Tot va quedar reduït a només un bloqueig i a aplicar represàlies dures contra les poblacions dels voltants, una situació a què va posar final la defecció de les mateixes tropes, que van abraçar la causa austria…
Les pratiques pédagogiques en première année universitaire: description et analyse de leurs implications sur la scolarité des étudiants
2014
In France, there is little research on university teaching and focusing specifically on teaching practices. This present research aims to explore this concept in two different ways. The first part focuses on the description of the practices implemented by teachers during first-year university lectures. Using in situ observation of lecture practices of 49 teachers from five programmes, we first show that teachers’ practices mostly rely on traditional methods as defined by Bru (2006). However, we show a variety of practices among teachers. The second part of this research updates our knowledge of the implications of these practices on student studies. 734 freshmen from these sectors were inte…
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…
Patterns of successful media production
2016
While it has been acknowledged that convergence is a multidimensional phenomenon, the convergence of media production processes has received little attention from researchers so far. In this article, we address this research gap with a qualitative study of production processes in different types of media. Our starting point is that independent of the media type, common product characteristics can be identified, that promote success in the audience market. We ask whether the same is true for process characteristics; whether there are converged processes that promote audience success independent of the media type. The study is based on n = 39 interviews in the German-speaking markets. Our fi…
