Effects of rainfall on Culex mosquito population dynamics
(2017)The dynamics of a mosquito population depends heavily on climatic variables such as temperature and precipitation. Since climate change models predict that global warming will impact on the frequency and intensity of ... -
Very fast dissolving acid carboxymethylcellulose-rifampicin matrix : development and solid-state characterization
(2017)One of the main obstacles to the successful treatment of tuberculosis is the poor and variable oral bioavailability of rifampicin (RIF), which is mainly due to its low hydrophilicity and dissolution rate. The aim of this ... -
Selección de parcelas control para estudios de la dinámica post-incendio : desempeño de rutinas no paramétricas y autorregresivas
(2017)Los regímenes naturales de incendios han sufrido modificaciones; consecuentemente, es indispensable disponer de herramientas robustas para el seguimiento post-fuego de la vegetación. Los satélites de alta resolución temporal ... -
Estudio experimental del efecto de la turbulencia sobre el espectro de tamaño de gotas de nube
(2017)El propósito de este trabajo es estudiar empíricamente el efecto sobre el espectro de tamaños de gotas en una nube cálida, sometida a perturbaciones que afectan el movimiento de la parcela de aire en donde se encuentra. ... -
Una mirada sobre el operativo aprender
(2017)El artículo presenta algunas reflexiones en torno al operativo de evaluación "Aprender". -
Problem of quantifying quantum correlations with non-commutative discord
(2017)In this work we analyze a non-commutativity measure of quantum correlations recently proposed by Y. Guo [Sci. Rep. 6, 25241 (2016)]. By resorting to a systematic survey of a two-qubit system, we detected an undesirable ... -
Structure constrained by metadata in networks of chess players
(2017)Chess is an emblematic sport that stands out because of its age, popularity and complexity. It has served to study human behavior from the perspective of a wide number of disciplines, from cognitive skills such as memory ... -
Unified framework to determine Gaussian states in continuous-variable systems
(2017)Gaussian states are the backbone of quantum information protocols with continuous-variable systems whose power relies fundamentally on the entanglement between the different modes. In the case of global pure states, knowledge ... -
Spherical analysis on homogeneous vector bundles of the 3-dimensional euclidean motion group
(2018)We consider R3 as a homogeneous manifold for the action of the motion group given by rotations and translations. For an arbitrary τ∈SO(3)ˆ, let Eτ be the homogeneous vector bundle over R3 associated with τ. An interesting ... -
Una experiencia vivida en aula : enseñar y aprender a trabajar con estadística desde una perspectiva crítica
(2015)En este artículo se presenta una descripción de una experiencia escolar realizada en una escuela secundaria de una localidad de la provincia de Córdoba donde la segunda autora se desempeña como profesora de matemática. La ... -
Dynamic heterogeneity in the monoclinic phase of CCl4
(2016)Carbon tetrachloride (CCl4) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuclear quadrupolar resonance (NQR) experiments ... -
Maximal totally geodesic submanifolds and index of symmetric spaces
(2016)Let M be an irreducible Riemannian symmetric space. The index i(M ) of M is the minimal codimension of a totally geodesic submanifold of M. In [1] we proved that i(M ) is bounded from below by the rank rk(M) of M, that is, ... -
Non-strongly isospectral spherical space forms
(2016)In this paper we describe recent results on explicit construction of lens spaces that are not strongly isospectral, yet they are isospectral on p-forms for every p. Such examples cannot be obtained by the Sunada method. ... -
Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams
(2016)The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ... -
Layered double hydroxides-indomethacin nanohybrids : intercalation, pH influence, stability and release properties
(2016)In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage ... -
Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
(2016)Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ... -
Construction of a quartz spherical analyzer : application to high-resolution analysis of the Ni Ka emission spectrum
(2016)The construction and characterization of a focusing X-ray spherical analyzer based on α-quartz 4404 are presented. The performance of the analyzer was demonstrated by applying it to a high-resolution X-ray spectroscopy ... -
ICME international survey on teachers working and learning through collaboration : June 2016
(2016)This article presents preliminary results from a survey commissioned for ICME 13 (2016) focusing on “Teachers Working and Learning Through Collaboration”. It takes as a starting point a previous survey, commissioned for ... -
Matrix Gegenbauer polynomials : the 2×2 fundamental cases
(2016)In this paper, we exhibit explicitly a sequence of 2 × 2 matrix valued orthogonal polynomials with respect to a weight W p,n , for any pair of real numbers p and n such that 0 < p < n. The entries of these polynomiales ... -
Gadolinium substitution effect on the thermomagnetic properties of Ni ferrite ferrofluids
(2016)This work is focused on the characterization of Ni-ferrite nanocrystals and their subsequent doping with Gd, in an attempt to explore Gd inclusion in the thermomagnetic properties of prepared ferrofluids. Spinel ferritesNiFe2O4, ...
