Star formation is fundamental for the processes of planet formation and galaxy evolution. Here we present an analysis of the gas kinematics of the ISF, a massive filament hosting a young embedded cluster, in the Orion A cloud through observations of different molecular transitions. We derive kine...

La formación estelar es fundamental para los procesos de formación planetaria y evolución de galaxias. Aquí presentamos un análisis cinemático del gas molecular del filamento ISF, un filamento masivo que contiene un cúmulo joven, en la nube de Orión A, a través de observaciones de distintas trans...

In this thesis, the vulnerability and capacity of acclimation to environmental stress related to Climate change mainly in Cystoseira tamariscifolia and other species as Ellisolandia elongata, Cystoseira compressa and Padina pavonica are evaluated. The effects of physical stressors as elevated irr...

En la presente tesis desarrollo una cronología de cambios en la vegetación y paleofuegos que abarca los últimos 17.000 años a partir de testigos de sedimentos lacustres obtenido de Laguna Churrasco (45°41’S, 71°49’O, 798 msnm), región de Aysén. El objetivo es documentar la historia de la vegetaci...

In this thesis I present a record of changes in vegetation and paleofires over the last 17,000 years from sediment cores obtained from Laguna Churrasco (45 ° 41'S, 71 ° 49'W, 798 masl), Aysén region. The objective is to document the history of vegetation and paleofires, their reciprocal relations...

Viruses are ubiquitous in all environments and hot-springs are not the exception even though its extreme conditions. Phototrophic mats of terrestrial hot-springs have been used for decades as models for understanding the composition, structure, and function of microbial communities in nature. The...

Los virus son ubicuos en todos los entornos y las fuentes termales no son la excepción a pesar de sus condiciones extremas. Los tapetes fototróficoss de las fuentes termales terrestres se han utilizado durante décadas como modelos para comprender la composición, estructura y función de las comuni...

Discarding Antarctic and sub Antarctic regions, the Andes concentrate almost 90% of glacier cover in the Southern Hemisphere. Large data gaps exist here, preventing detailed knowledge on how climate determines glacier behavior. As Andean glaciers are distributed in a latitudinal transect spanning...

Los biotensoactivos son moléculas anfipáticas compuestas por dos regiones, una hidrofílica y otra hidrofóbica. Son excretados extracelularmente por diferentes microorganismos, tales como bacterias, hongos y levaduras. Dentro de estos existen los biosurfactantes que disminuyen la tensión superfici...

Heap bioleaching technology has been successfully applied at an industrial scale for over 30 years, and is generally considered to be the most effective engineering option to bio-process low-grade copper sulfide ores. Heap bioleaching was established at the Escondida mine in Chile in 2006, and cu...
