One-stage laser-microtextured implants immediately placed in the inter-radicular septum of molar fresh extraction sockets associated with GBR techniq…
2018
Background The outcome of one-stage trans-mucosal immediate implants with simultaneous guided bone regeneration (GBR) technique has become highly predictable. Furthermore, when this approach is performed to place one-stage implants into the inter-radicular septum of fresh extraction sockets in the molar region, the risk of incorrect emergence profile and off-angle loading is reduced. The aim of the present study was to clinically evaluate the horizontal hard and soft tissue changes, and radiographically the vertical socket walls remodeling, and the early peri-implant marginal bone loss (EMBL) following the placement of immediate one-stage implants in the inter-radicular septum of molar fres…
Phytophthora Root and Collar Rot of Paulownia, a New Disease for Europe
2021
Paulownia species are fast growing trees native to China, which are being grown in managed plantings in several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, and collapse, as a consequence of root and crown rot, were observed in around 40% of trees of a 2-year-old planting of Paulownia elongata × P. fortunei in Calabria (Southern Italy). Two species of Phytophthora were consistently recovered from roots, basal stem bark, and rhizosphere soil of symptomatic trees and were identified as Ph. nicotianae and Ph. palmivora on the basis of both morphological characteristics and phylogenetic analysis of rDNA ITS sequences. Koch’s postulates…
A novel Usher protein network at the periciliary reloading point between molecular transport machineries in vertebrate photoreceptor cells.
2008
Contains fulltext : 69178.pdf (Publisher’s version ) (Closed access) The human Usher syndrome (USH) is the most frequent cause of combined deaf-blindness. USH is genetically heterogeneous with at least 12 chromosomal loci assigned to three clinical types, USH1-3. Although these USH types exhibit similar phenotypes in human, the corresponding gene products belong to very different protein classes and families. The scaffold protein harmonin (USH1C) was shown to integrate all identified USH1 and USH2 molecules into protein networks. Here, we analyzed a protein network organized in the absence of harmonin by the scaffold proteins SANS (USH1G) and whirlin (USH2D). Immunoelectron microscopic anal…

Temporary Strengthening Technique of Marble Columns with Steel Wires and Wood Spars
2014
Granite, marble and heavy stone columns have been used in the architects from all the ages to answer to both aesthetical and structural requirements in ancient churches and historical buildings. Such materials offer great visual impact and have mechanical properties that allow their use in construction and to obtain bright and slender structures. Marble is a very high strength but brittle material. It often occur that marble or granite columns of historical building are cracked along their height due to external actions and the risk of buckling occurs. Because this kind of failure is sudden and very brittle in stone and rocks, an immediate strengthening of the columns is needed. Among e tem…
IL WHISTLE-BLOWING COME STRUMENTO DI CONTROLLO INTERNO DELLE ORGANIZZAZIONI
2009
Il Whistle-Blowing come strumento di controllo interno delle organizzazioni Nelle organizzazioni pubbliche e private si consumano abusi di vario ordine e grado. Si tratta di condotte che non sempre sono definibili come reati in senso tecnico ma che tuttavia sono censurabili, al pari dei reati, perché capaci di produrre danni gravi alla società e alle stesse organizzazioni. Gli abusi cui si fa riferimento vengono commessi nell’abituale esercizio di funzioni istituzionali, manageriali, specialistiche e, perfino, esecutive. La tradizione culturale sociologica e criminologica li ha ascritti tra i cosiddetti crimini dei colletti bianchi, sebbene la locuzione abbia assunto nel corso del tempo anc…
Dynamic behaviour of cracked granite and marble columns retrofitted with steel collars
2014
Marble and heavy stone columns are widely diffused in ancient churches and historical buildings in all the Mediterranean area. Their good mechanical properties allowed carrying great load values, while their bright colours and aesthetical characteristics have been used by a lot of ancient architects to achieve structural solutions with great visual impact. Despite their good compressive strength, marble columns could be damaged from environmental effects (e.g. longterm effects or thermal loads), which could crack the structural members. In this way, the slenderness of the column increases drastically and the presence of an imposed ground shaking could be critical, since the column will be m…
Discrepancy between individual and organizational values : occupational burnout and work engagement among white-collar workers
2013
Abstract This pilot study aimed to investigate the level of discrepancy between individual and organizational values, and assessed its impact on white-collar workers' job burnout and work engagement. The study examined the hypothesis that the better the fit between individual and organizational values, the higher the work engagement and the lower the risk of professional burnout. The modified Schwartz's typology of values, focusing on work related issues, was used as a framework for the study. Also, organizational level analysis was incorporated into the study questionnaire in order to capture the potential mismatch effect between the person and his or her work environment. A total of 480 w…
Soft tissue integration of different abutment surfaces: An experimental study with histological analysis
2021
OBJECTIVE To evaluate whether abutment surface and surface bio-activation have an effect on soft tissue morphogenesis. MATERIALS AND METHODS 36 patients (36 implants) were included. Abutments were randomly divided into 4 groups (n = 9): Smooth Surface-MAChined (MAC), Ultrathin Threaded Microsurface (UTM), MAC Plasma of Argon activated (Plasma-MAC), and UTM Plasma of Argon activated (Plasma-UTM). After 2 months of healing, soft tissue samples were collected and prepared for histological analysis. The margin of the peri-implant mucosa (PM), the apical extension of the barrier epithelium (aJE), and the apical location of the abutment (AM) were identified. Significances of differences among gro…
Il boss mafioso ieri ed oggi. Caratteristiche psicologiche e dati di ricerca
2014
L’articolo descrive le caratteristiche psicologiche dei boss di Cosa Nostra a partire dai dati di ricerca raccolti in quasi un ventennio (1994-2013). Attraverso l’utilizzo di frammenti di interviste a collaboranti di giustizia, mogli, figli, cognate, si analizza la figura del boss e il suo contesto relazionale. L’articolo riporta, inoltre, i risultati di una recente ricerca sulla relazione tra boss e colletti bianchi, realizzata attraverso l’analisi delle intercettazioni ambientali registrate a casa di un noto boss mafioso siciliano: Giuseppe Guttadauro. Da questa ricerca emerge la diversità psicologica su cui si fonda la relazione tra boss e colletto bianco. L’analisi dei trascritti delle …
