Caraibi: un "archipel inachevé"
2018
L’etichetta “Letterature franco-caraibica” utilizzata, per convenzione, dalla critica per indicare unitariamente la produzione letteraria in lingua francese della regione centrale del Continente americano è assai impropria. La regione dei Caraibi abbraccia, infatti, sia alcune delle isole dell’arcipelago delle Piccole Antille (Martinica, Guadalupa), sia l’isola di Haïti, che fa parte delle Grandi Antille, che la Guiana incastonata sulla costa orientale dell’America meridionale. Pur nella diversità dei movimenti ideologici e degli avvenimenti storici che si sono succeduti nella regione, le opere letterarie degli scrittori caraibici francofoni, nel loro insieme, hanno oscillato, e continuano …
Una tabla inédita de Fernando Yáñez y nueva luz sobre su estancia en Almedina (1518-1525)
2020
The contribution presents a new acquisition for the catalog of Fernando Yáñez, a Holy Family dating back to 1523, shedding new light on the artist?s production in the third decade of the sixteenth century during his return to Almedina, his birthplace, in a time frame that divides the works for Valencia, like the retablo mayor for the city?s cathedral, from his altarpieces for Cuenca.
Measurement of t ¯ t production with a veto on additional central jet activity in pp collisions at √ s = 7 TeV using the ATLAS detector
2012
A measurement of the jet activity in t[bar over t] events produced in proton–proton collisions at a centre-of-mass energy of 7 TeV is presented, using 2.05 fb[superscript −1] of integrated luminosity collected by the ATLAS detector at the Large Hadron Collider. The t[bar over t] events are selected in the dilepton decay channel with two identified b-jets from the top quark decays. Events are vetoed if they contain an additional jet with transverse momentum above a threshold in a central rapidity interval. The fraction of events surviving the jet veto is presented as a function of this threshold for four different central rapidity interval definitions. An alternate measurement is also perfor…
Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting
2016
We measure the top quark mass in dilepton final states of top-antitop events in proton-antiproton collisions at sqrt(s) = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb^-1 at the Fermilab Tevatron Collider. The analysis features a comprehensive optimization of the neutrino weighting method to minimize the statistical uncertainties. We also improve the calibration of jet energies using the calibration determined in top-antitop to lepton+jets events, which reduces the otherwise limiting systematic uncertainty from the jet energy scale. The measured top quark mass is mt = 173.32 +/- 1.36(stat) +/- 0.85(syst) GeV.
Study of archaeological ceramics from northern Bactria in Late Antiquity and Early Middle Ages (3rd-7th centuries AD)
2023
Esta tesis se centra en el análisis arqueológico y arqueométrico de cerámicas kusháno-sasánidas (ss. III-IV d.C.) y altomedievales (ss. V-VIII d.C.) procedentes de diferentes yacimientos localizados en el sector septentrional de la antigua Bactriana (Asia Central). Bactriana, o Tokharistán, como fue llamada desde finales del siglo IV d.C. (Litvinsky, 1998), fue una de las satrapías del Imperio Aqueménida que incluía los territorios al norte y al sur del antiguo río Oxus (ahora Amu Darya), actualmente correspondientes al sur de Uzbekistán, sur de Tayikistán y norte de Afganistán. La región se caracterizó por contactos continuos entre pueblos, debidos a migraciones, invasiones y comercio. Des…

The design is based on a new modelling approach under the assumption of normbounded…
On a stochastic disease model with vaccination
2006
We propose a stochastic disease model where vaccination is included and such that the immunity isn’t permanent. The existence, uniqueness and positivity of the solution and the stability of disease free equilibrium is studied. The numerical simulation is done.
Fatty Acids as Biomarkers of the Production Season of Caciocavallo Palermitano Cheese
2021
Simple Summary In the Mediterranean environment, climatic variability determines a discontinuity in the forage availability of pastures. Caciocavallo Palermitano is a cheese obtained from the milk of the Cinisara cattle breed, mainly raised on pasture. The present study investigated the fatty acid profile of cheeses produced in two typical farms in the four seasons of the year, with the aim of identifying specific fatty acids that can be used as biomarkers to discriminate the productions obtained in the different seasons, in order to economically enhance those seasonal productions that have better health characteristics. The results revealed the possibility of distinguishing spring producti…
Measurement methodology for greenhouse gas emissions from storage of forest chips–A review
2015
Abstract Research on greenhouse gas emission related to solid biofuels has focused mainly on the emissions from end use and the production chain. GHG emissions from the storage of forest chips have not received much attention in recent literature. In order for EU emission reduction targets to be fully understood, emissions from solid biofuel storage needs to be better described. Usually emissions from chip piles have been modelled using studies from organic waste composting but these two materials can differ appreciably; for example the C/N-ratio and moisture content. Herein, previous studies on greenhouse gas emissions from forest chips piles during storage are reviewed. The objective is t…
