Histological study of human periodontal tissue following biologically oriented preparation technique (BOPT)
2020
Background The aim of this study was to conduct histological analysis of a human tooth resected with the periodontal insertion apparatus intact following treatment using biologically oriented preparation technique (BOPT). Material and methods This descriptive histological dento-periodontal study used an anterior tooth extracted with the surrounding periodontal tissues intact, following prosthetic restoration with BOPT. The sample patient was recruited from among those attending the Department of Dental Medicine at the Faculty of Medicine and Dentistry, University of Valencia (Spain). Eight serial sections of the restored tooth were processed. The relative location and histological character…
Post-orthodontic position of lower incisors and gingival recession: A retrospective study
2017
Background To evaluate if changes in lower incisor position following orthodontic treatment are correlated with development of gingival recessions. Material and methods Pre- and post-treatment digital models and lateral cephalograms of 22 subjects were collected retrospectively. The clinical crown length, gingival scallop, and papilla height of the central lower incisor were measured along with the cephalometric incisor's inclination, the distance from the mandibular plane, and the distance between the Infradentale and Menton points. Statistical correlations between gingival and cephalometric variables were studied. In addition, two groups were defined based on the post-treatment incisor in…
La Corona d'Aragona nel Mediterraneo: precedenti e conseguenze della migrazione albanese nell'italia meridionale aragonese
2018
Political, economic and military framework of the Albanian immigration in Sicily in the 15th Century. The Crown of Aragon plays a leading role in the Western politics towards Othman expansion and conquest in the Balcans, together with the Italian merchant cities. The article describes the premises of the support given by Alfonso the Magnanimous to the Albanian resistence leaded by Giorgio Skanderbeg and to the immigration of Albanian people to Southern Italy after the Othman conquest of their land.

Badania dotyczą zmienności zawartości olejku eterycznego w igliwiu sosny zwyczajnej w zależności od wieku drzew, garnituru igieł oraz jego usytuowania w koronie. Materiał do badań stanowiło igliwie zebrane z drzewostanów sosnowych w wieku 15, 44 i 89 lat. W przeprowadzonych badaniach średnia zawartość olejków wzrastała wraz z wiekiem drzew. W igliwiu pochodzącym z 15-letniego młodnika zawartość olejku wynosiła średnio 0,46%, a w igliwiu drzewostanów 44- i 89-letnich odpowiednio 0,55 i 0,61%. Średnia zawartość olejku maleje wraz z wiekiem igliwia. Najwięcej olejku zawiera igliwie jednoroczne - 0,56%, najmniej igliwie trzyletnie - 0.48%. W drzewostanie 15-letnim stwierdzono wyraźny wzrost wyd…

Bis(hydroxyammonium) hexachloridoplatinate(IV)–18-crown-6 (1/2)
2014
In the title complex, (NH3OH)2[PtCl6]·2C12H24O6, the PtIV atom is coordinated by six chloride anions in a slightly distorted octahedral geometry. The Pt—Cl bond lengths are comparable to those reported for other hexachloridoplatinate(IV) species. The hydroxyammonium groups act as linkers between the [PtCl6]2− anion and the crown ether molecules. The anion is linked to two hydroxyammonium cations via O—H...Cl hydrogen bonds and each hydroxyammonium moiety is linked to a crown ether molecule by hydrogen bonds between ammonium H atoms and 18-crown-6 O atoms. The crown ether molecules have the classic crown shape in which all O atoms are located in the inner part of the crown ether ring and all…
Meandry politycznej kariery Andrzeja Lipskiego (1572-1631). Eksluteranin biskupem krakowskim
2018
Andrzej Lipski (1572–1631) pochodził ze średnioszlacheckiej rodziny wyznania lute- rańskiego. Studiował na uczelniach protestanckich (1582–1594 – Strasburg, Heidelberg) i katolickich (1603–1605 – Rzym), uzyskując doktorat obojga praw. Karierę Lipskiego w kancelarii koronnej przyspieszyło przejście na katolicyzm, obranie stanu duchowego i protekcja biskupa-podkanclerzego Piotra Tylickiego, wpływowego stronnika kanclerza Jana Zamoyskiego. Lipski należał wówczas do duchowieństwa państwowego, które słu- żyło królowi i Rzeczypospolitej, a dochody czerpało z beneficjów, o których uzyskanie łatwiej było przy dworze. Odejście z elity władzy Zamoyskiego jego stronników w 1605 r. oraz sympatyzowanie …
Monitoraggio e valutazione del danno degli insetti defogliatori su diverse specie di Quercus in Sicilia
Most of the insects feeding on oaks are usually ‘in balance’ with their host trees, causing occasional damage. When severe defoliations regularly occur, oak trees vulnerability to the complex of factors causing the overall decline syndrome can increase. Assessing canopy damage due to defoliating insects through the usually adopted visual methods is quite difficult, requiring highly experienced operators and a long time spent to collect field data. The present research has been carried out to investigate the different susceptibility of Sicilian oak species to defoliating insect attacks, in particular the oak moth Tortrix viridana (L.) (Lepidoptera Tortricidae), with the aim to assess the rel…

Bartomeu de Tresbens, physician and astrologer in the service of king Peter the Ceremonious and the infant John: between the service to the Crown and…
2018
Bartomeu de Tresbens was a physician, astrologer and philosopher at the service of two kings of the Crown of Aragon, Peter IV the Ceremonious and his son, Duke John, the future John I the Hunter, between 1360 and 1375, approximately. His major work of astrological content has hardly been studied, except for the Llibre de les nativitats (Book of Nativities). Similarly, most of his biography is not known. The documents, which are mainly the correspondence of its relationship with the monarchy, are preserved, but also other records that connect him to the municipalities of Barcelona and Cervera. Particularly in the latter case, Tresbens was tempted by the municipal authorities for being the ph…
