  • Development of a computational model of abscess formation 

    Pigozzo, Alexandre B.; Missiakas, Dominique; Alonso Muñoz, Sergio; Weber dos Santos, Rodrigo; Lobosco, Marcelo (2018-06-26)
    Article
    Accés obert
    In some bacterial infections, the immune system cannot eliminate the invading pathogen. In these cases, the invading pathogen is successful in establishing a favorable environment to survive and persist in the host organism. ...

  • Experimental study of a microchannel bubble injector for microgravity applications 

    Arias Calderón, Santiago; Ruiz, X; Casademunt Viader, Jaume; Ramírez de la Piscina Millán, Laureano; González Cinca, Ricardo (2009-01)
    Article
    Accés restringit per política de l'editorial
    We perform a quantitative characterization of a microbubble injector in conditions relevant to microgravity. The injector pregenerates a slug flow by using a capillary T-junction, whose operation is robust to changes in ...

  • Pattern forming instabilities of the nematic smectic-B interface 

    Toth-Katona, T; Börzsönyi, T; Buka, A; González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume; Hernández-Manchado, A; Kramer, L (2000-10)
    Article
    Accés restringit per política de l'editorial
    Free growth properties of the smectic B liquid crystalline phase into the supercooled nematic have been investigated in quasi-two-dimensional geometry. Different orientation combinations of the two phases have been achieved ...

  • Heat diffusion anisotropy in dendritic growth: phase field simulations and experiments in liquid crystals 

    González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume; Hernández Machado, Aurora; Toth-Katona, T; Börzsönyi, T; Buka, A (1998-10)
    Article
    Accés restringit per política de l'editorial
    An anisotropic heat diffusion coefficient is introduced in order to study some interfacial growth phenomena. This anisotropy has been incorporated in a phase field model which has been studied numerically to reproduce some ...

  • Modeling random crawling, membrane deformation and intracellular polarity of motile amoeboid cells 

    Alonso Muñoz, Sergio; Stange, Maike; Beta, Carsten (Public Library of Science (PLOS), 2018-08-01)
    Article
    Accés obert
    Amoeboid movement is one of the most widespread forms of cell motility that plays a key role in numerous biological contexts. While many aspects of this process are well investigated, the large cell-to-cell variability ...

  • Bubble dynamics in turbulent duct flows: Lattice-Boltzmann simulations and drop tower experiments 

    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-23)
    Article
    Accés obert
    Lattice-Boltzmann simulations of a turbulent duct flow have been carried out to obtain trajectories of passive tracers in the conditions of a series of microgravity experiments of turbulent bubble suspensions. The statistics ...

  • Generation and control of monodisperse bubble suspensions in microgravity 

    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-01)
    Article
    Accés obert
    A new experimental setup for the generation of homogeneous, monodisperse bubble suspensions in turbulent duct flows in microgravity has been designed and tested in drop tower experiments. The setup provides independent ...

  • Periodic spiking by a pair of ionic channels 

    Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María (2018-09-01)
    Article
    Accés obert
    Neuronal cells present periodic trains of localized voltage spikes involving a large amount of different ionic channels. A relevant question is whether this is a cooperative effect or it could also be an intrinsic property ...

  • Fixed-density boundary conditions in overdamped Langevin simulations of diffusion in channels 

    Ramírez de la Piscina Millán, Laureano (2018-07)
    Article
    Accés obert
    We consider the numerical integration of Langevin equations for particles in a channel, in the presence of boundary conditions fixing the concentration values at the ends. This kind of boundary condition appears for instance ...

  • Using archaeomagnetism to improve the dating of three sites in Catalonia (NE Spain) 

    Casas, Lluís; Auguet Sangrá, Carlota E.; Cantoni, Gerard; López Vilar, Jordi; Guasch Ferré, Núria; Prevosti Monclús, Marta (2018)
    Article
    Accés obert
    Archaeomagnetic dating was performed on four archaeological structures in Catalonia (NE Spain) using magnetic inclination and declination values from three reference curves: the Iberian SVC and two curves computed using ...

  • Seedling emergence through soil surface seals under laboratory conditions: effect of mechanical impedance and seal moisture 

    Mas Serra, Maite; Verdú González, Antoni Maria Claret; Ginovart Gisbert, Marta; Josa March, Ramon (2017)
    Article
    Accés obert
    It is well known that soil sealing strongly affects seedling emergence. The effect of soil sealing on the emergence of flax and turnip seedlings was studied in the laboratory. Seeds were sown in pots, watered, then covered ...

  • How to deal with the modelling of epidemics? Some ideas and examples to be implemented in the classroom! 

    Ginovart Gisbert, Marta (2017)
    Article
    Accés restringit per política de l'editorial
    The general objective of this work is to deal with different approaches for the representation of an epidemic considering the state of the individuals in the population, Susceptible, Infected or Recovered (SIR), which ...
