En las últimas décadas las nanoestructuras del tipo core@shell han sido ampliamente utilizadas en el campo de la Catálisis Heterogénea. Este tipo de materiales se caracterizan por poseer un núcleo (core) recubierto por una o más capas (shell), formando una estructura con diferentes componentes fu...
In the last decades, core@shell nanostructures have been widely used in heterogeneous catalysis. Characteristic features of these materials are the presence of a core covered by one or more shell forming a functional multi-component structure integrated in a single unity. Core@shell structures ha...
We prove an inequality concerning isometries of a Gromov hyperbolic metric space, which does not require the space to be proper or geodesic. It involves the joint stable length, a hyperbolic version of the joint spectral radius, and shows that sets of isometries behave like sets of 2×2 real matri...
El Altiplano chileno está representado por muchos cuerpos de agua,
entre los cuales se encuentran, el lago Chungará en el norte y Salar de
Ascotán en el sur que se encuentra a 21,5° S de latitud aproximadamente a
3720 msnm. En el salar de Ascotán se distr
The geomorphology of the Mejillones Peninsula, northern Chile, evidences a Quaternary
tectonic uplifting process. Upper plate faults located close to the peninsula show recent activity.
However, there is no consensus about the uplift rate of the Mejillones Peninsula in the millennial
timescale an...
We investigate remarkable phenomena in nonlinear systems associated with intrinsically non-linear heterogeneities, motivated by real-world situations. We study the nonlinear dynamics in parametrically driven systems and their applications in the context of hydrodynamics and magnetic materials. Us...
This thesis is dedicated to the study of the stationary Boussinesq system:
u + (u r)u + r = g in

In this thesis, I had studied the mechanisms of cell death induced by the action of visible light and flavin photosensitizers in both human HL-60 leukemia cells, and HeLa human cervix epithelioid carcinoma cells, which grow attached to the substrate forming a monolayer. It is demonstrated that th...
En esta tesis, he estudiado los mecanismos de muerte celular inducidos por acción de la luz visible y fotosensibilizadores flavínicos en células humanas de leucemia HL-60, y en células de carcinoma de útero HeLa, que crecen adheridas al sustrato formando una monocapa. Se demostró que la acción co...
En Homo sapiens, la masculinidad ha sido considerada como un conjunto de características que se correlacionan entre sí, tales como rasgos morfológicos y de comportamiento. En esta tesis se estudió la asociación entre masculinidad facial, rasgos de las manos y personalidad (entendida como las dife...
In Homo sapiens, masculinity has been considered as a set of features that correlate with each other, such as morphological and behavioral traits. In this thesis, the association between facial masculinity, hand features and personality (understood as individual differences in behavior) was analy...
