Europa social: cuestiones para un futuro debate
2021
El presente trabajo tiene por objeto abordar determinadas cuestiones que, a juicio de la autora, deberían ser tratadas en un futuro debate sobre la Europa social. Para ello, se presentará, como punto de partida, la situación actual del denominado Modelo social europeo a partir de un recorrido por la configuración de las diferentes técnicas de creación del derecho social europeo: armonización de las legislaciones, diálogo social, método abierto de coordinación y ¿constitucionalización¿ de los derechos sociales. Una segunda parte del trabajo se dedicará a plantear ciertos temas concretos que deberían ser objeto de tratamiento en el futuro, entre ellos, los siguientes: la reformulación del art…
The genus Isoëtes L. (Lycophyta, Isoëtaceae): Synthesis of karyological data
2001
Summary A synthesis of relevant karyological data regarding the genus Isoetes is given, with an up-to-date check list of chromosome numbers including 152 records referring to 67 taxa (62 species and 5 infraspecific taxa) and 16 hybrids. Total of different chromosome counts (considering two or more cytotypes for certain taxa, excluding hybrids) is 80. Probable base number is x = 11, even though x = 10 and x = 12 have been proposed for certain species. On the basis of data here summarized, the mean percentage of polyploidy is 61.2%; 31 taxa are diploids (38.8%), 28 are tetraploids (35.0%), 8 are hexaploids (10.0%), with a few species each which are tri-, penta-, octo-, deca- and dodeca-ploids…

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the…
2013
A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb[superscript −1] of pp collision data at s√ = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of various simplified supersymmetry-inspired models where gluinos are pair produced, as well as an mSUGRA/CMSSM model.

Light-component spectrum of the primary cosmic rays in the multi-TeV region measured by the ARGO-YBJ experiment
2012
The ARGO-YBJ experiment detects extensive air showers in a wide energy range by means of a full-coverage detector which is in stable data taking in its full configuration since November 2007 at the YBJ International Cosmic Ray Observatory (4300 m a.s.l., Tibet, People's Republic of China). In this paper the measurement of the light-component spectrum of primary cosmic rays in the energy region $(5\textdiv{}200)\text{ }\text{ }\mathrm{TeV}$ is reported. The method exploited to analyze the experimental data is based on a Bayesian procedure. The measured intensities of the light component are consistent with the recent CREAM results and higher than that obtained adding the proton and helium sp…

In this work we have studied the response of alanine pellets with and without gadolinium exposed to the thermal column of the TRIGA Mark II research reactor at the University of Mainz
Search for ultrarelativistic magnetic monopoles with the Pierre Auger Observatory
2016
We present a search for ultra-relativistic magnetic monopoles with the Pierre Auger Observatory. Such particles, possibly a relic of phase transitions in the early universe, would deposit a large amount of energy along their path through the atmosphere, comparable to that of ultrahigh-energy cosmic rays (UHECRs). The air shower profile of a magnetic monopole can be effectively distinguished by the fluorescence detector from that of standard UHECRs. No candidate was found in the data collected between 2004 and 2012, with an expected background of less than 0.1 event from UHECRs. The corresponding 90% confidence level (C.L.) upper limits on the flux of ultra-relativistic magnetic monopoles ra…
The analysis of the material deprivation of foreigners in Italy.
2013
We examine the material deprivation of foreigners on a sub-sample of the 2009 Italian Survey on Income and Living Conditions. We employ two indices of material deprivation that take into account the regional level of our analysis, and rely on the assignment of weights to items. The determinants of material deprivation are investigated through a zero-inflated beta model.
