    • Study of lead levels in soils by weathering of metallic Pb bullets used in dove hunting in Córdoba, Argentina 

      Rubio, Marcelo; Germanier, Alejandro; Mera, María Fernanda; Faudone, Sonia Nerina; Sbarato, Rubén Darío; Campos, José Manuel; Zampar, Vanesa; Bonzi, Edgardo Venusto; Pérez, Carlos (2014)
      A study of level of Pb in soils of the center-north of the Province of Córdoba, a worldwide recognized tourist region for dove hunting, was performed in this work. The native forest of the region has a great population ...

    • Study of the characteristic parameters of the normal voices of Argentinian speakers 

      Bonzi, Edgardo Venusto; Grad, Gabriela B.; Maggi, Alicia M.; Muñóz, Marta R. (2014)
      The voice laboratory permits to study the human voices using a method that is objective and noninvasive. In this work, we have studied the parameters of the human voice such as pitch, formant, jitter, shimmer and harmonic-noise ...

    • Swap logic 

      Areces, Carlos Eduardo; Fervari, Raúl Alberto; Hoffmann, Guillaume Emmanuel (2014)
      We investigate dynamic modal operators that can change the model during evaluation. We define the logic SL by extending the basic modal language with the ♦ modality, which is a diamond operator that in addition has the ...

    • Synthesis, structural characterization and magnetic properties of the monoclinic ordered double perovskites BaLaMSbO6, with M = Mn, Co and Ni 

      Blanco, M. Cecilia; De Paoli, Juan M.; Ceppi, Sergio; Tirao, Germán Alfredo; Nassif, Vivian M.; Guimpel, J.; Carbonio, Raúl E. (2014)
      Double perovskites BaLaMnSbO6, BaLaCoSbO6 and BaLaNiSbO6, were synthesized by conventional ceramic method in air, as polycrystalline powders. The Mn and Ni compounds belong to the I 2/m monoclinic space group, while the ...

    • Tailoring optical fields emitted by nanometric sources 

      Bustos Marún, Raúl Alberto; Dente, Axel Damián; Coronado, Eduardo Andrés; Pastawski, Horacio Miguel (2014)
      In this work we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system studied consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is ...

    • The growth of ice particles in a mixed phase environment based on laboratory observations 

      Castellano, Nesvit Edit; Ávila, Eldo Edgardo; Burgesser, Rodrigo Exequiel; Saunders, Clive P. R. (2014)
      This paper describes new laboratory observations about the size evolution of ice crystals and cloud droplets immersed in a mixed-phase cloud. The experiments were performed by using a cloud chamber facility for three ...

    • Virtual laboratory for a first experience in dynamics 

      Ré, Miguel Ángel; Giubergia, María Fernanda (2014)
      New technologies contribute to the learning process of scientific disciplines. In particular Physics learning may take advantage of these techniques by implementing experimental practices in simulation environments. Our ...

    • Water and membrane dynamics in suspensions of lipid vesicles functionalized with poly(ethylene glycol)s 

      Clop, Eduardo Matias; Chattah, Ana Karina; Perillo, María Angélica (2014-05-08)
      The present work was aimed at studying the molecular dynamics at different levels of model membranes having a simulated glycoclix, with focus on the molecular crowding conditions at the lipid–water interfacial region. Thus, ...

    • Weighted inequalities for some integral operators with rough kernels 

      Riveros, María Silvina; Urciuolo, Marta (2014)
      In this paper we study integral operators with kernels K(x, y) = k1(x − A1y)...km(x − Amy), ki(x) = Ωi(x) |x|n/qi where Ωi : Rn → R are homogeneous functions of degree zero, satisfying a size and a Dini condition, Ai are ...
