    • Monares Ruiz, Andrés; Schmal Simon, Rodolfo (Universidad Alberto Hurtado, 2004)
      El trabajo ha sido concebido por el cristianismo occidental como una forma ética: la conducta para procurarse el sustento es definida como virtuosa, a la vez que un medio para glorificar a Dios. Dentro de ese enfoque ...
    • Elduque, Alberto; Labra, Alicia (Taylor and Francis Ltd., 2019)
      The affine group scheme of automorphisms of an evolution algebra ε with ε 2 is shown to lie in an exact sequence → D → Aut(E) → S, where D, diagonalizable, and S, constant, depend solely on the directed graph associated ...
    • Rojas, Pedro; Ulloa, Hugo; Niño, Yarko (Springer Netherlands, 2018)
      Gravity waves are prominent physical features that play a fundamental role in transport processes of stratified aquatic ecosystems. In a two-layer stratified basin, the equations of motion for the first vertical mode are ...

(Universidad California Press, 2018-05-03)
      Worldwide, urbanization constitutes a major and growing driver of global change and a distinctive feature of the Anthropocene. Thus, urban development paths present opportunities for technological and societal transformations ...
    • Vásquez, M.; Nieto, F.; Morata Céspedes, Diego; Droguett, B.; Carrillo Rosua, F. J.; Morales, S. (Elsevier, 2014)
      HRTEM textural evidence shows that clay minerals in the Tinguiririca geothermal field (Andean Cordillera, central Chile) are the result of direct alteration of former volcanic glass and minerals by hydrothermal fluids at ...
    • Castruccio Álvarez, Angelo; Rust, A.C.; Sparks, R.S.J. (Springer-Verlag Berlin Heidelberg, 2013)
      We present a simple tool to evaluate the dominant dynamical regime of a lava flow and to estimate the order of magnitude of the main rheological parameter (viscosity or yield strength) controlling the length of the lava ...
    • Durrett, Rick; Remenik Zisis, Daniel (Springer, 2012)
      The problem of how often to disperse in a randomly fluctuating environment has long been investigated, primarily using patch models with uniform dispersal. Here, we consider the problem of choice of seed size for plants ...
    • Fuente, Alberto de la; Shimizu, Kenji; Imberger, Jörg; Niño Campos, Yarko (AMER SOC LIMNOLOGY OCEANOGRAPHY, 2008-11)
      The evolution of internal waves in a two-layer rotating circular lake was studied under nonlinear and weak nonhydrostatic effects. Inclusion of nonlinear acceleration allowed the waves to steepen at the rear of the crest ...
    • Rodríguez, I.; Roche, O.; Moune, S.; Aguilera, F.; Campos, E.; Pizarro, M. (Elsevier, 2015)
      The Irruputuncu is an active volcano located in northern Chile within the Central Andean Volcanic Zone (CAVZ) and that has produced andesitic to trachy-andesitic magmas over the last ~258 ± 49 ka.We report petrographical ...
    • Janknecht, E.; Reimers, D.; López, S.; Tytler, D. (EDP SCIENCES S A, 2006-11)
      We investigate the evolution and the statistical properties of the Ly alpha absorbers of the intergalactic medium (IGM) in the largely unexplored redshift range z = 0.5-1.9. We use high-resolution (R = 30 000) UV (STIS) ...
    • Treister, Ezequiel; Urry, C. Megan (UNIV CHICAGO PRESS, 2006-12-01)
      In order to study the evolution of the relative fraction of obscured active galactic nuclei (AGNs), we constructed the largest sample to date of AGNs selected in hard X-rays. The full sample contains 2341 X-ray-selected ...
