  • Relationship between climate variability indices and airborne pollination in Catalonia (NE Iberian Peninsula) 

    Alarcón Jordán, Marta; Belmonte, Jordina; Majeed, Husam Tareq; Periago Oliver, M. Cristina; Izquierdo Miguel, Rebeca (2014)
    Conference report
    Open Access
    Here we explore the effect of climatic variability on the airborne pollen series recorded in Catalonia (NE Iberian Peninsula) considered of high interest due to abundance, landscape importance and/or allergenic significance. ...
  • Homothetic motions and Newtonian cosmology 

    Jaen Herbera, Javier; Molina Compte, Alfred (2014-05-07)
    Article
    Restricted access - publisher's policy
    We construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is achieved through an equivalence principle based on a local homothetic frame of ...
  • A conceptual discussion on electromagnetic units - Extending mechanical units towards a global system of units 

    Jaen Herbera, Javier; Bohigas Janoher, Xavier; Pejuan Alcobé, Arcadi (2014-05)
    Article
    Restricted access - publisher's policy
    A comparative review of the different systems of units that are most usual in electromagnetism leads to the proposal of a new system of units. In this system, the gravitational constant acquires the role of an interaction ...

  • Rigid motions and generalized Newtonian gravitation 

    Jaen Herbera, Javier; Molina Compte, Alfred (2013-08-01)
    Article
    Restricted access - publisher's policy
    In an effort to contribute to a better understanding of General Relativity, here we lay the foundations of generalized Newtonian gravity, which unifies inertial forces and gravitational fields. We also formulate a kind ...
  • Comparative study of three audio processors as environments for laboratory activities on wave physics and acoustics 

    Pejuan Alcobé, Arcadi; Bohigas Janoher, Xavier; Jaen Herbera, Javier; Periago Oliver, M. Cristina (2013-08)
    Article
    Restricted access - publisher's policy
    Audio processors allow to implement laboratory activities specially on acoustics. We have evaluated three audio processors (Audacity, WaveLab, and Adobe Audition). Although an overall grade was also calculated as a ...
  • Misconceptions about sound among engineering students 

    Pejuan Alcobé, Arcadi; Bohigas Janoher, Xavier; Jaen Herbera, Javier; Periago Oliver, M. Cristina (2012)
    Article
    Open Access
    Our first objective was to detect misconceptions about the microscopic nature of sound among senior university students enrolled in different engineering programmes (from chemistry to telecommunications). We sought to ...
  • Refredament magnètic: ordre i desordre d'imants atòmics 

    Bohigas Janoher, Xavier (2011)
    Article
    Open Access
    S’ha comprovat que la refrigeració magnètica que utilitza un sistema magnètic és energèticament eficient i competitiva amb la tecnologia refrigerant basada en la compressió de gasos en el rang de temperatures proper a ...
  • Entorn virtual d’aprenentatge autònom 

    Periago Oliver, M. Cristina; Jaen Herbera, Javier; Bohigas Janoher, Xavier; Pejuan Alcobé, Arcadi (2010)
    Conference lecture
    Open Access
    En aquesta ponència presentem un Entorn Virtual d’Aprenentatge (EVA) dissenyat per fomentar l’aprenentatge autònom [1,2,3]. Es tracta d’una activitat dirigida en la qual se suggereixen les accions que l’estudiant ha de ...
