La presente tesis doctoral, estudia la reducción electroquímica de dióxido de carbono en líquidos iónicos con complejos tetraazamacrociclicos de Co (III), Ni (II) del tipo cyclam (1,4,8,11-tetraazaciclo tetradecano) y la obtención de carbonatos cíclicos m
En esta tesis doctoral se presentan tres nuevas familias de soluciones analíticas que describen objetos extendidos en teorías de gravedad. La primera familia corresponde a soluciones de cuerda negra en la teor a general de la relatividad en cuatro dimensiones con constante cosmológica negativa ac...
In the present thesis, three new families of analytical solutions that describe extended objects in gravity theories are presented.The first family corresponds to black string solutions of the general theory of relativity in four dimensions with negative cosmological constant coupled to anon line...
Salmonella Typhi (S. Typhi), a Gram-negative bacterium, is an intracellular facultative pathogen that causes typhoid fever in humans, and is ingested primarily by water and contaminated food. Once in the intestine, the bacteria invade non-phagocytic cells, such as epithelial cells of the intestin...
Salmonella Typhi (S. Typhi), una bacteria Gram negativo, es un patógeno intracelular facultativo que causa fiebre tifoidea en humanos, y que es ingerida principalmente por agua y alimentos contaminados. Una vez en el intestino, la
bacteria invade células no fagocíticas, como las células epitelia...
Los microorganismos que habitan ambientes acídicos (pH < 3) están expuestos a factores ambientales altamente estresantes, como altas concentraciones de protones, metales y sulfato; tales factores colocan a los acidófilos en un alto riesgo de generar grandes cantidades de especies reactivas de oxí...
La captura eficiente de energía solar, para generar dihidrógeno a partir de la fotoelectrólisis del agua o generar corriente empleando celdas solares sigue siendo uno de los mayores desafíos a los que se enfrenta la ciencia hoy en día. Los compuestos fotoactivos actualmente disponibles para ser e...
This study addresses the interplay between strain/stress fields and paleo-fluid migration in the Southern Andean Volcanic Zone (SVZ). The SVZ coexists with the margin-parallel Liquiñe-Ofqui Fault System (LOFS) and with NW-striking Andean Transverse Faults
The bacterial division es an esential process that is executed by a complex of proteins, called
divisome. FtsW and FtsI are membrane proteins part of this machinery, that form a complex.
This complex is formed in the late phase of division after the chromosome segregation and
FtsQ/FtsB/FtsL compl...
Alzheimer's Disease (AD) is histopathologically characterized by the presence, within the brain, of lesions called senile plaques (SP) and neurofibrillary tangles (NFT). SP are fibrillar deposits mainly composed by beta-amyloid peptide. SP onset is an early event in AD pathogenesis, and for that ...

The sediment transport driven by a river or a channel flow is a phenomenon that operates at different scales. At the smallest scales, the coherent structures of the turbulent boundary layer are the mechanisms that govern the entrainment. At a greater scale, observed now from a particle ensemble p...
