(MDPI, 2020)Biodegradable polymer scaffolds filled with bioactive glass particles doped with therapeutic metal ions are a novel and promising strategy to repair critical-sized bone defects. In this study, scaffolds based on a poly (D, ...
-
(Springer, 2020)We show, in Hilbert space setting, that any two convex proper lower semicontinuous functions bounded from below, for which the norm of their minimal subgradients coincide, they coincide up to a constant. Moreover, under ...
-
(MDPI, 2020)The results of an experimental study on the condition of incipient transport of non-cohesive particles due to the flow of a power-law fluid in a rectangular pipe are presented in this article. The pipe can change its ...
-
(MDPI, 2020)Speech enhancement is one of the most important fields in audio and speech signal processing. The speech enhancement methods are divided into the single and multi-channel algorithms. The multi-channel methods increase the ...
-
(American Institute of Mathematical Sciences, 2020)The centralizer (automorphism group) and normalizer (extended symmetry group) of the shift action inside the group of self-homeomorphisms are studied, in the context of certain Z(d) subshifts with a hierarchical supertile ...
-
(Wiley, 2020)Production of biomass and lipids in batch cultures of the Antarctic thraustochytridOblongichytriumsp. RT2316-13, is reported. The microorganism proved capable of producing nearly 67% docosahexaenoic acid (DHA) and 15% ...

(Universidad de Chile, 2020)Los eventos de vientos extremos representan una amenaza a los sistemas eléctricos de distribución. Para mitigar este tipo de amenazas, cada vez más frecuentes e intensas debido a los efectos del cambio climático, se requiere ...
-
(Universidad de Chile, 2020)El proyecto de rediseñar el proceso de estimación de la demanda, se lleva a cabo en Comercializadora Novaverde S.A, Guallarauco, proceso que impacta principalmente al área comercial y marketing, abastecimiento, producción, ...
-
(Universidad de Chile, 2020)El presente trabajo se enfoca en la modelación numérica de medios porosos que poseen aguas con una diferencia de densidad considerable, donde se genera una interfaz salina la cual es estudiada y analizada, determinado su ...
-
(Universidad de Chile, 2020)A lo largo de su desarrollo la implementación de Lean en la industria de la construcción se ha caracterizado por esfuerzos centrados mayormente en el uso de herramientas del tipo Last Planner System, sin dar mayor énfasis ...

(Springer, 2020)The ordinary differential equation x˙ (t) = f(x(t)), t ≥ 0, for f measurable, is not sufficiently regular to guarantee existence of solutions. To remedy this we may relax the problem by replacing the function f with its ...
-
(Wiley, 2020)This paper identifies four attentional processes that increase efficiency and accuracy in repeated lexicographic tasks using an instructed strategy approach. We propose a framework to decompose attentional effort used to ...
-
(Copernicus Gesellschaft, 2020)Over the past decades, several numerical models have been developed to understand, simulate and predict debris flow events. Typically, these models simplify the complex interactions between water and solids using a ...
-
(Oxford University Press, 2020)Despite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H-0) in the Hubble-Lemaitre law remain unknown. To break the current ...
-
(Universidad de Chile, 2020)La relación entre las precipitaciones en Chile y el fenómeno de El Niño en la escala interanual ha sido estudiada desde principios de los 1980s. Las teleconexiones tropicales, mediadas por las ondas de Rossby que se propagan ...
