Diseño e integración de energía geotérmica de baja entalpía aplicada a proyectos de construcción residencial
(Universidad de Chile, 2013)
estudios económicos en Santiago y Puerto Montt, comparando los costos de calefaccionar, logrando el confort térmico, en tres viviendas distintas por medio de la geotermia de baja entalpía y sistemas convencionales de calefacción más representativos en las...

Evaluación económica de reprocesamiento de relaves en tranques abandonados incorporando incertidumbre de precios de commodities y valor en riesgo
(Universidad de Chile, 2021)
Los tranques de relaves abandonados conforman un riesgo tanto para el ambiente como para las comunidades aledañas a estos, debido a los potenciales minerales dañinos contenidos en el relave y a la posibilidad de un colapso del muro de la represa...
Filosofía sin menos : el pensamiento de Carlos Vaz Ferreira como posible estética del modernismo
(Universidad de Chile, 2013)
terquedad de quien escribe, pues han sido múltiples las instancias para discutirlo. No puedo más que agradecer a los distintos organizadores y contertulios, por la paciencia y lucidez de interrogaciones que, de una u otra forma, fueron fundamentales para...
Aplicación de una batería de marcadores microsatélite para evaluar la diversidad genética, estructura poblacional y su estabilidad temporal, en mytilus chilensis del sur de chile
(Universidad de Chile, 2018)
Chile es el segundo productor y el primer exportador de mundial de mejillones del género Mytilus. El comercio internacional de alimentos requiere de sistemas de trazabilidad “del mar a la mesa” que permitan asegurar su calidad, inocuidad y...
Chile is the second producer and the world's leading exporter of mussels of the genus Mytilus. The international food trade requires traceability systems "from the sea to the table" to ensure its quality, safety and authenticity. To verify the administrative traceability systems, methods based on DNA analysis have been used, studying the genetic diversity, population structure and its temporal stability. This baseline allows the application of algorithms to assign individuals to their place of origin, verifying the information contained in the labeling. Our objective was to evaluate the genetic diversity, population structure and temporal stability of Mytilus chilensis in 6 localities of southern Chile, between 2009 and 2013, using 14 SSR loci. The 14 loci analyzed were polymorphic and on average 13.49 and 13.64 alleles were found per locus in 2009 and 2013 respectively. Significant deviations from the HWE were observed in 133 of the 165 tests performed. Slight population structure was found, the global fixation index (FST) values in 2009 and 2013 were low (0.014 and 0.009, respectively) but significantly different from zero (P <0.01) and genetic differentiation (FST) between pairs of localities was significant in 11 of the 15 comparisons made in 2009 and in 7 of the 15 comparisons made in 2013. The hierarchical space-time AMOVA analysis showed that there was no difference between the years, but the greatest variation of allele frequencies is found within the localities (97.77% in 2009 and 98.37% in 2009), the rest of the variation was due to differences between the localities. The total panel of 14 loci correctly assigned over 61% of the individuals to zones, while to locations it was only 36%. Although the correct allocation percentage was more than double that expected by chance, it is not sufficient for traceability purposes, so it is recommended to improve the marker panel with loci with greater allocation power or with SNP-type markers...
