    • Anion Exclusion in PFLOTRAN: Development and Reactive Transport Simulations 

      Bruch Molist, Paula (Universitat Politècnica de Catalunya, 2021-11-01)
      Master thesis
      Restricted access - author's decision
      The Swedish Nuclear Fuel and Waste Management Company (SKB) [1] is in charge of dealing safely with all the radioactive waste from nuclear power plants in Sweden. In 2009 Forsmark (Sweden) was selected to build the spent ...

    • Cylindrical geometry: a further step in active microwave tomography 

      Broquetas Ibars, Antoni; Jofre Roca, Lluís; Cardama Aznar, Ángel; Elias Fusté, Antoni; Rius Casals, Juan Manuel; Romeu Robert, Jordi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1991-05-01)
      Article
      Open Access
      A prototype imaging system for active microwave tomography using cylindrical geometry has been developed, making it possible to obtain images of the dielectric properties of biological targets at 2.45 GHz. This configuration ...

      Restricted access - publisher's policy
      This paper presents measurements of the effect of the atmospheric radioactive release from the Fukushima Dai-ichi nuclear power station at three sites belonging to the Spanish environmental monitoring system. Measured ...

    • Inter-islands optical link tests 

      Comerón Tejero, Adolfo; Bará Temes, Francisco Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1990-05-01)
      Article
      Open Access
      Free-space optical communication systems between satellites and also between a satellite and a ground station foreseen in Europe in the mid-1990's require far-field on-ground experimentation prior to launch. To identify ...

    • Neutron capture cross section measurements for nuclear astrophysics at CERN n TOF 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (Elsevier Science Publishers B.V. NORTH HOLLAND, 2004)
      Article
      Restricted access - publisher's policy
      A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton ...

    • Quantitative images of large biological bodies in microwave tomography by using numerical and real data 

      Mallorquí Franquet, Jordi Joan; Joachimowicz, N.; Broquetas Ibars, Antoni; Bolomey, J. C. (Jean-Charles) (IEE-INST ELEC ENG, 1996-11-01)
      Article
      Open Access
      A new inverse microwave imaging algorithm is presented which has the ability to obtain quantitative dielectric maps of large biological bodies. By using a priori information, obtained with a first order algorithm, the final ...

    • The presence of radionuclides in wastewater treatment plants in spain and their effect on human health 

      Montaña Gurrera, Montserrat; Camacho García, Antonia; Devesa, Ricard; Valles Murciano, M. Isabel; Cespedes, R.; Serrano Carreño, M. Isabel; Blázquez Pérez, Sonia M.; Barjola Molina, Vanessa (2013-12-01)
      Article
