    Article
    Accés obert
    This work presents the Monte Carlo simulations performed with the MCNPX and GEANT4 codes for the design of a BEta deLayEd Neutron detector, BELEN-20. This detector will be used for the study of beta delayed neutron emission ...
  • Development and assessment of fire-related risk unavailability matrices to support the application of the maintenance rule in a PWR nuclear power plant 

    Díaz Bayona, Pedro; Estruch Traveria, Enric; Dies Llovera, Javier; Tapia Fernández, Carlos; Blas Del Hoyo, Alfredo de; Asamoah, Matthew (2016-06-17)
    Article
    Accés restringit per política de l'editorial
    Two methods are presented which serve to incorporate the fire-related risk into the current practices in nuclear power plants with respect to the assessment of configurations. The development of these methods is restricted ...
  • Characterization of a neutron-beta counting system with beta-delayed neutron emitters 

    Agramunt Ros, Jorge; Taín, J.L.; Gómez Hornillos, María Belén; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Pretel Sánchez, Carme; Riego Pérez, Albert; Tarifeño Saldivia, Ariel Esteban (2016-01-21)
    Article
    Accés restringit per política de l'editorial
    A new detection system for the measurement of beta-delayed neutron emission probabilities has been characterized using fission products with well known ß-delayed neutron emission properties. The setup consists of BELEN-20, ...
  • Fractal structure and predictive strategy of the daily extreme temperature residuals at Fabra Observatory (NE Spain, years 1917-2005) 

    Lana Pons, Francisco Javier; Burgueño, August; Serra de Larrocha, Carina; Martínez Santafé, Maria Dolors (2015-07-01)
    Article

    A compilation of daily extreme temperatures recorded at the Fabra Observatory (Catalonia, NE Spain) since 1917 up to 2005 has permitted an exhaustive analysis of the fractal behaviour of the daily extreme temperature ...
  • Aftershock sequences of three seismic crises at southern California, USA, simulated by a cellular automata model based on self-organized criticality 

    Monterrubio Velasco, Marisol; Lana Pons, Francisco Javier; Martínez Santafé, Maria Dolors (2015-03-01)
    Article
    Accés restringit per acord de confidencialitat
    Several properties of aftershock series related to the main shocks of Landers, Northridge and Hector Mine (southern California, USA) are reproduced by the Dynamic Fiber Bundle Model, DFBM. Optimum values for the three ...
  • Criticality in the slowed-down boiling crisis at zero gravity 

    Charignon, Thomas; Lloveras Muntané, Pol Marcel; Chatain, Denis; Truskinovsky, Lev; Vives, Eduard; Beysens, Daniel; Nikolayev, Vadim (2015-05-12)
    Article
    Accés restringit per política de l'editorial
    Boiling crisis is a transition between nucleate and film boiling. It occurs at a threshold value of the heat flux from the heater called CHF (critical heat flux). Usually, boiling crisis studies are hindered by the high ...
  • Slow relaxation dynamics and aging in random walks on activity driven temporal networks 

    Sousa da Mata, Angelica; Pastor Satorras, Romualdo (Springer, 2015-02-04)
    Article
    Accés obert
    We investigate the dynamic relaxation of random walks on temporal networks by focusing in the recently proposed activity driven model [N. Perra, B. Gon, calves, R. Pastor-Satorras, A. Vespignani, Sci. Rep. 2, 469 (2012)]. ...
  • Insights into Q2Qbar2 states from an effective perspective 

    Ametller Congost, Lluís; Talavera Sánchez, Pedro (American Physical Society, 2015-10-07)
    Article
    Accés obert
    We discuss the two-photon coupling of the lightest scalar meson on the basis of an extension of χPT. Using low-energy data on the pion form factor and the γγ→π+π−(π0π0) cross sections as inputs, we find Γ(σ→γγ)≅0.126  keV. ...
  • Is long range transport of pollen in the NW Mediterranean basin influenced by Northern Hemisphere teleconnection patterns? 

    Izquierdo Miguel, Rebeca; Alarcón Jordán, Marta; Periago Oliver, M. Cristina; Belmonte Soler, Jordina (2015-11-01)
    Article
    Accés obert
    Climatic oscillations triggered by the atmospheric modes of the Northern Hemisphere teleconnection patterns have an important influence on the atmospheric circulation at synoptic scale in Western Mediterranean Basin. ...
  • Phase transition in hydrogen-bonded 1-adamantane-methanol 

    Ben Hassine, Bacem; Negrier, Philippe; Barrio Casado, María del; Mondieig, Denise; Massip, Stephane; Tamarit Mur, José Luis (2015-08-01)
    Article
    Accés obert
    The polymorphism of 1-adarnantane-methanol C11H18O has been investigated by differential thermal analysis and single-crystal and powder X-ray diffraction. Below the melting temperature (389.5 +/- 0.4 K), this compound ...
