Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO

2019

We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino beams on nuclear targets. In addition, a set of proton baseline PDFs is fitted within the same framework with the same theoretical assumptions. The results of this global QCD analysis are compared to existing nPDF sets and to the fitted cross sections. Also, the uncertainties resulting from the limited constraining power of the included experimental data are presented. The published work is based on an open-source tool, xFitter, which has been modified to be ap…

Hexagonal Microparticles from Hierarchical Self-Organization of Chiral Trigonal Pd3L6 Macrotetracycles

2021

Construction of structurally complex architectures using inherently chiral, asymmetric, or multi-heterotopic ligands is a major challenge in metallosupramolecular chemistry. Moreover, the hierarchical self-organization of such complexes is unique. Here, we introduce a water-soluble, facially amphiphilic, amphoteric, chiral, asymmetric, and hetero-tritopic ligand derived from natural bile acid, ursodeoxycholic acid. We show that via the supramolecular transmetalation reaction, using nitrates of Cu(II) or Fe(III), and subsequently Pd(II), a superchiral Pd3L6 complex can be obtained. Even though several possible constitutional isomers of Pd3L6 could be formed, because of the ligand asymmetry a…

Intensified job demands in healthcare and their consequences for employee well-being and patient satisfaction: A multilevel approach

2021

Contains fulltext : 234355.pdf (Publisher’s version ) (Open Access) Aims: Intensified job demands (IJDs) and their effects on employee burnout, work engagement and patient satisfaction were investigated across different work units and occupational groups in a healthcare setting. Design: A multilevel study. Methods One thousand twenty-four healthcare employees responded to a survey in 2019 and rated their experiences of IJDs, burnout and work engagement. Nine hundred fifty-one patients rated their satisfaction with care received from healthcare staff. Results: Work units and occupational groups who shared more experiences of increased time pressure and multitasking reported higher exhaustion…

Stratificazioni e progetto nel centro storico di Palermo. Una esperienza didattica in fieri

2019

Al Dipartimento di Architettura dell’Università degli Studi di Palermo, il Direttore – il professore Andrea Sciascia – ha proposto di sperimentare una didattica intensiva per i laboratori di progettazione architettonica di terzo anno a partire dall’anno accademico 2019 – 2020 (i laboratori sono condotti dai docenti Gianfranco Tuzzolino, Adriana Sarro e Luciana Macaluso). Il primo periodo di attività, di nove giorni, è stato dedicato al progetto di una piccola moschea (per circa trenta fedeli) nel centro storico di Palermo, a piazza Sant’Eligio. Il luogo è il palinsesto di numerose stratificazioni che si sono sovrapposte nel tempo divenendo da più o meno labili tracce, strutture solide. Nell…

Attraversamento trasversale Torre dell'Orsa-Aeroporto-Statale

2014

Il progetto si inserisce all’interno del tema della città in estensione, e si propone di determinare una nuova continuità nel territorio agricolo di Cinisi. A partire dalla scelta di interrare la linea ferrata, eliminando così il passaggio a livello in località Bosco Tagliato, il parco agricolo diventa un’occasione per irrorare di una più densa continuità il tessuto sfrangiato delle piccole residenze di villeggiatura. Il rapporto tra la viabilità lenta e la grande scala degli assi di percorrenza veloce è risolto attraverso il progetto di suolo, che consente una permeabilità est-ovest e nord-sud, cioè mare-monte, mettendo in relazione due belvedere con la costa e la tonnara Orsa attraverso p…

The lived experience of rescuing people who have driven into floodwater: Understanding challenges and identifying areas for providing support.

2018

Background: Drowning is a major public health issue, with risk increasing during times of flood. Driving into floodwater is a major risk factor for flood-related drowning and injury, and despite widespread public health campaigns, many people continue to undertake this risky behaviour and require rescue. Purpose: We aimed to identify key challenges faced by emergency services personnel when rescuing those who have driven into floodwater, and to identify strategies for supporting rescuers in this important role. Methods: Australian flood rescue operators (N = 8) who had previously rescued a driver who had driven into floodwater participated in semi-structured interviews. Data were analysed u…

SICILY: THE OVERWHELMING FLUXES OF MASS TOURISM, IMMIGRATION AND STREET MARKETS

2016

Tre progetti sono sviluppati nello stupendo, sebbene in parte distrutto, centro storico di Palermo, il quarto si trova invece ad Agrigento sulla costa sud ovest della Sicilia, un sito archeologico di rinomanza mondiale. Lo scenario di questi progetti è la Sicilia dei prossimi anni nella quale enormi masse di persone arriveranno. - Da un lato il turismo di massa con il suo straripante sviluppo porterà gente al Nord - principalmente Palermo – e loro molto spesso si dirigeranno a Sud a vedere le rovine greche. - similmente una latrettanto enorme massa di gente disperata sbarcherà avventurosamente sulla costa sud e farà lo stesso percorso ma in verso opposto verso Palermo, tappa intermedia vers…

The importance of psychological variables in the perceived exertion of young football players

2017

Las escalas para medir la percepción del esfuerzo están entre los métodos que han sido utilizados para el control y la evaluación de la carga interna del entrenamiento en deportes de equipo como el fútbol. Debido a su naturaleza psicofisiológica, su registro proporciona información proveniente tanto de indicadores fisiológicos como psicológicos del deportista. Dentro del marco de la Teoría de la Autodeterminación (SDT, Self Determination Theory; Deci & Ryan, 1985; Ryan & Deci, 2017) y de la Teoría de las Metas de Logro (AGT, Achievement Goal Theory; Ames, 1992; Nicholls, 1989), en esta tesis doctoral se estudian tanto las variables contextuales desadaptativas (dimensiones del clima motivaci…
