Dones i ciència. Quatre pioneres en el camp de la psicologia
2012
Una carrera científica normalment és una carrera d'obstacles, però en el cas de ser una dona s’afegeixen problemes i mecanismes d'exclusió específics. Per tal de conèixer les estratègies utilitzats per superar alguns obstacles, al present article revisem les biografies de quatre psicòlogues que, entre 1890 i 1940, van intentar obtenir una formació acadèmica i van aconseguir fer una contribució pròpia a la ciència psicològica.
Computed positron lifetimes in vacancies and vacancy-iron clusters in gold
1983
Abstract Annihilation characteristics are calculated for positrons trapped in clean and impurity decorated vacancy clusters in Au. The positron lifetime depends strongly on the structure of the clusters. In a strongly relaxed vacancy cluster, the lifetime can become smaller than the lifetime in a single vacancy. The substitution of some neighbour atoms of a vacancy cluster by Fe atoms has only a minor effect on the positron lifetimes.
Positron preferential annihilation in Bi-Sb alloys
2009
We report the measurements of the positron annihilation characteristics, i.e., positron lifetime and coincidence Doppler broadening spectra performed on five Bi-Sb alloys having a Bi content between 12.5 and 81 at.%. The strong effect of the preferential annihilation of positrons with the electrons of the Bi atoms has been revealed in these alloys.

IL CANTIERE DEL COMPLESSO CARMELITANO DELL’ANNUNZIATA A TRAPANI NELLA SECONDA METÀ DEL CINQUECENTO
2016
Il complesso carmelitano dell’Annunziata a Trapani, costituito dalla chiesa e dal convento annesso (oggi sede del Museo Regionale Agostino Pepoli), appare come un’architettura fortemente stratificata, frutto di una lunga e complessa vicenda progettuale che si snoda dal XIV secolo fino alla metà del Settecento. Il presente studio intende contribuire alla conoscenza del cantiere dell’Annunziata nella seconda metà del Cinquecento, un periodo ancora poco indagato dalle ricerche finora condotte sulla fabbrica, offrendo in particolare alcune riflessioni sui maestri impegnati nella costruzione del complesso architettonico, a partire dall’esame della documentazione relativa alla gestione amministra…
Synthesis of the new ring system 6,8-dihydro-5H-pyrrolo[3,4-h]quinazoline
2009
Abstract A convenient synthesis of the pyrrolo[3,4- h ]quinazoline ring system is reported. Our synthetic approach consisted of the annelation of a pyrimidine ring to an isoindole moiety using tetrahydroisoindole-4-ones as building blocks. The antiproliferative activity of the new compounds was investigated and one of them showed antitumor activity against all the 59 tested cell lines at micromolar concentrations (1.46–18.4 μM).
Outcomes of aortic valve repair according to valve morphology and surgical techniques
2012
OBJECTIVES: The aim of this study was to assess the impact of aortic valve morphology and different surgical aortic valve repair techni- ques on long-term clinical outcomes. METHODS: Between February 2003 and May 2010, 216 patients with aortic insufficiency underwent aortic valve repair in our institu- tion. Ages ranged between 26 and 82 years (mean 53 ± 15 years). Aortic valve dysfunctions, according to functional classification, were: type I in 55 patients (25.5%), type II in 126 (58.3%) and type III in 35 (16.2%). Sixty-six patients (27.7%) had a bicuspid valve. Aortic valve repair techniques included sub-commissural plasty in 138 patients, plication in 84, free-edge reinforcement in 80,…
