Measurement of the 238 U ( n , gamma ) cross section up to 80 keV with the Total Absorption Calorimeter at the CERN n_TOF facility
(AMER PHYSICAL SOC, 2017-12-01)
Article
Open AccessThe radiative capture cross section of a highly pure (99.999%), 6.125(2) grams and 9.56(5) 10-4 atoms/barn areal density 238-U sample has been measured with the Total Absorption Calorimeter (TAC) in the 185 m flight path ... -
Monte Carlo simulations for the study of a moderated neutron detector
(2011-08-12)
Article
Open AccessThis 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
(2016-06-17)
Article
Open AccessTwo 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
(2016-01-21)
Article
Open AccessA 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)
(2015-07-01)
Article
Restricted access - author's decisionA 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
(2015-03-01)
Article
Restricted access - confidentiality agreementSeveral 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
(2015-05-12)
Article
Restricted access - publisher's policyBoiling 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
(Springer, 2015-02-04)
Article
Open AccessWe 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
(American Physical Society, 2015-10-07)
Article
Open AccessWe 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?
(2015-11-01)
Article
Open AccessClimatic 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
(2015-08-01)
Article
Open AccessThe 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 ... -
Epidemic processes in complex networks
(2015-08-31)
Article
Open AccessIn recent years the research community has accumulated overwhelming evidence for the emergence of complex and heterogeneous connectivity patterns in a wide range of biological and sociotechnical systems. The complex ...
