Metallothionein genes in the sea urchin Paracentrotus lividus
2014
Metallothioneins (MTs) constitute a heterogeneous superfamily of cysteine rich proteins, which coordinate divalent (Zn2+, Cd2+) or monovalent (Cu+) metal ions. Several functions have been proposed for these peptides, ranging from toxic metal protection to physiological metal homeostasis, free radical scavenging, oxidative stress protection, antiapoptotic defense, control of the redox status of the cell and also a role during development. Regarding the MT system in vertebrates’ nearest kin, little information is available at present. Recently MTs were also characterized in cephalochordates. Hence in order to shed some light on MT origin and functional differentiation through evolution, we st…

Advances in the endoscopic management of malignant biliary obstruction
2020
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an al…
Procedure for Safety Assessment and BIM Modelling of an Historical Complex Structure through a Macroelement Approach: The Building “Molino-Pastificio…
2022
The structural assessment of existing historical structures is a complex task due to the inner main difficulty in making up reliable models for structural analysis, able to include mechanical and geometrical nonlinearities, existing damage, complex configurations and arrangements of materials. This task becomes more difficult in mixed RC-masonry structures, which structural modelling can be particularly tough due to the different connections and interactions between structural members and materials. This paper presents the case study of a multi-storey mixed Reinforced Concrete (RC)- masonry historical structure, namely the former mill “Molino-Pastificio Soresi” building, located in Partinic…
Crystal structure and Hirshfeld surface analysis of [N(CH3)4][2,2′-Fe(1,7-closo-C2B9H11)2]
2017
Abstract This work investigates the meta -ferrabis(dicarbollide) anion that was isolated as salt of tetramethylammonium. The structure of the obtained crystal consisted of discrete [2,2′-Fe(1,7- closo -C 2 B 9 H 11 ) 2 ] − anions and disordered [N(CH 3 ) 4 ] + cations. The anion had a considerable chemical stability ensured by ionic and Van der Waals interactions. Thus, Hirshfeld surfaces and fingerprint plot were used to visualize, explore, and quantify intermolecular interactions in the crystal lattice of the title compound. This investigation proved that close contacts were dominated by H⋯H interactions.
Autorreflexión pedagógica
2019
The autobiographical reflection on school learning makes it possible to explain how personal life guidelines are loading teaching activity with experiences. Educational time does not consist only of a linear narration, but works as the evocation of temporal and spatial memories of an explanation of the present. Personal life is intertwined with school reflection to give meaning to what we decide from teaching
STUDENTS’ PERSPECTIVES ON THE IMPLEMENTATION OF MUSICAL ACTIVITIES IN PRESCHOOL EDUCATION
2018
Aim. The aim of the study is to find out students’ perspectives on the necessity, readiness and disturbing factors of implementing musical activities in preschool. The theoretical part of the paper describes the particularity of preschool teachers’ work, the children’s interest in musical activities, and the benefits of implementing musical activities in preschool. 
 Method. The empirical study involved 168 students (N=168), of which 132 students (N=132) are already working as preschool teachers in parallel with their study at the university. The study identified three questions: why do preschool teachers use musical activities? What factors prevent a preschool teacher from using music…
Effects of contextual variables on strategic investment decision-making styles: An empirical study from Pakistan.
2022
There is a gap in the literature of strategic investment decision making (SIDM) concerning the links between context variables, infrastructure and SIDM practices (or SIDM styles) in developing countries. This research aims to fill that gap. Survey data (N = 128) from the manufacturing companies listed on the Pakistan Stock Exchange was collected via an e-mailed questionnaire and visits to the companies. Data are analyzed with factor analysis and multiple regression analysis. The results reveal what we call four different SIDM styles (or emphases): managerial power-, financial analysis-, top management-, and strategy-based investing. These styles are considered to be novel perspectives on SI…
Undervisning og vurdering anno 2016 : et elevperspektiv
2016
Masteroppgave pedagogikk - Universitetet i Agder 2016 Prosjektets bakgrunn: Globalisering og internasjonale trender påvirker i økende grad Europas og Norges utdanningspolitiske avgjørelser i form av reformer og læreplaner. Vi lever i en tid med stadige endringer og dette har også innvirkning på skolen. Elevenes resultater blir i økende grad, og betydelig gjennom media, brukt som indikasjon på om skolene og lærere mestrer sitt yrke og sin profesjon. Enkelte politiske partier har, som OECD anbefaler, også fremmet ønske om lærerlønn på bakgrunn av dokumentert elevresultat. Hensikt: Hensikten med studien er å innhente kunnskap om hvordan elever selv opplever lærerrollen, undervisning og vurderi…
The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces
2020
In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…
