      Article
      Restricted access - publisher's policy
      A method for the experimental measurement of inter-particle forces (secondary Bjerknes force) generated by the action of an acoustic field in a resonator micro-channel is presented. The acoustic radiation force created by ...
    • Chemically bonded cements formulated with by-products of magnesium oxide 

      Formosa Mitjans, Joan; Aranda, Ma; Chimenos Ribera, Josep Maria; Rosell Amigó, Juan Ramón; Ginés, O.; Fernández Renna, Ana Inés (2008-10)
      Article
      Open Access
      The casting of magnesium and potassium phosphate (KMgPO4•6H2O; K-struvite) cements becomes possible after the aqueous reaction between magnesium oxide and potassium dihydrogen phosphate. This reaction is quite exothermic ...
    • Heat storage and electricity generation in the Moon during the lunar night 

      Climent, Blai; Torroba, Oscar; González Cinca, Ricardo; Ramachandran, Narayanan; Griffin, Michael D. (2013-08-01)
      Article
      Restricted access - publisher's policy
      One of the biggest challenges of the exploration of the Moon is the survival of the crew and the lunar assets during the lunar night. The environmental conditions on the lunar surface and its cycle, with long periods of ...
    • Multilevel analysis of calcium dynamics in stimulated cultures of cardiomyocytes 

      Vallmitjana Lees, Alexander; Hove-Madsen, Leif; Barriga, Montserrat; Benítez Iglesias, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      We present an automatic method to characterize calcium activity in a culture of cardiac cells from a sequence of microscopy fluorescence images. The approach quantifies both the response of each individual cell in the ...
    • Phospholamban knockout breaks arrhythmogenic Ca2+ waves and suppresses catecholaminergic polymorphic ventricular tachycardia in mice 

      Bai, Yunlong; Jones, Peter; Guo, Jiqing; Zhong, Xiaowei; Clark, Robert; Zhou, Qiang; Wang, Ruiwu; Vallmitjana Lees, Alexander; Benítez Iglesias, Raúl; Hove-Madsen, Leif; Semeniuk, Lisa; Guo, Ang; Song, Long-Sheng; Duff, Henry J.; Chen, S.R. Wayne (2013-07-15)
      Article

      Rationale: Phospholamban (PLN) is an inhibitor of cardiac sarco(endo)plasmic reticulum Ca2+ ATPase. PLN knockout (PLN-KO) enhances sarcoplasmic reticulum Ca2+ load and Ca2+ leak. Conversely, PLN-KO accelerates Ca2+ ...
    • Speeding chemical reactions by focusing 

      Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María; Lindenberg, Katja (2013-04-11)
      Article
      Open Access
      We present numerical results for a chemical reaction of colloidal particles which are transported by a laminar fluid and are focused by periodic obstacles in such a way that the two components are well mixed and consequently ...
    • Stochastic Phase-Field simulations of symmetric alloy solidification 

      Benítez Iglesias, Raúl; Ramírez de la Piscina Millán, Laureano (2004-09)
      Article
      Open Access
      We study initial transient stages in directional solidification by means of a non-variational phase field model with fluctuations. This model applies for the symmetric solidification of dilute binary solutions and does not ...
    • Phase-field models in interfacial pattern formation out of equilibrium 

      González Cinca, Ricardo; Folch, R.; Benítez Iglesias, Raúl; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Hernández-Machado, A. (NOVA, 2004-06)

    • Dependency of calcium alternans on Ryanodine Receptor Refractoriness 

      Álvarez Lacalle, Enrique; Rodríguez Cantalapiedra, Inma; Peñaranda Ayllón, Angelina; Cinca, J.; Hove-Madsen, Leif; Echebarría Domínguez, Blas (2013-02-04)
      Article
      Open Access
      Background Rapid pacing rates induce alternations in the cytosolic calcium concentration caused by fluctuations in calcium rele However, the relationship between calcium alternans and refractoriness of the SR calcium ...
    • Experimental analysis of the bubble-slug transition in a flow generated by a T-junction in a minichannel with air/water and air/ethanol mixtures in conditions relevant to microgravity 

      Arias Calderón, Santiago; González Cinca, Ricardo (2013-01-31)
      Article
      Restricted access - publisher's policy
      We present an experimental study on the bubble–slug flow pattern transition which takes place in two-phase flows in microgravity related conditions. Two different sets of experiments were performed on ground with air/water ...
    • Study of a system to generate electricity on the Moon's surface during the lunar night
