Stopping power of palladium for protons in the energy range 0.300-3.100 MeV
(2013)The stopping power of palladium for protons has been measured using the transmission method with an overall uncertainty of around 5% over the energy range Ep=(0.300–3.100) MeV. These stopping power data are then compared ... -
Strictly positive solutions for one dimensional nonlinear elliptic problems
(2014)We study the existence and nonexistence of strictly positive solutions for the elliptic problems -- in a bounded open interval, with zero boundary conditions, where -- is a strongly uniformly elliptic differential operator, ... -
Study of Kb X-ray emission spectroscopy applied to Mn(2x)V(1-x)O4 (x=0 and1/3) oxyspinel and comparison with XANES
(2014-03)Oxidation state and coordination of transition metal cations seems to be hard to assess when considering multiple cations, each one with different possible oxidation states. In fact, this is the case of the spinel-type ... -
Study of lead levels in soils by weathering of metallic Pb bullets used in dove hunting in Córdoba, Argentina
(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
(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
(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
(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
(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
(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
(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
(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
(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 ...
