Optical waveguides fabricated in Cr:LiSAF by femtosecond laser micromachining
(Elsevier Science, 2017-11)
In this work we present the fabrication of double-track type II waveguides written in 1% doped Cr:LiSrAlF6 (Cr:LiSAF) crystal by femtosecond laser micromachining. We studied waveguides fabricated at energies from 1 to 7 ...
Actividad coagulante de la semilla annona muricata (guanábana) en aguas de la cuenca media del Río Bogotá
(Ingeniería AmbientalUniversidad El BosqueFacultad de Ingeniería, 2021)
High turbidity concentrations in water bodies are responsible for limiting crop irrigation, which are located in some zones of the country, as in the case of Bogotá, Colombia. There are some methods for the removal of the ...
Ambient noise tomography across the Central Andes
(Oxford University Press, 2013-09)
The Central Andes of southern Peru, Bolivia, Argentina and Chile (between 12°S and 42°S) comprise the largest orogenic plateau in the world associated with abundant arc volcanism, the Central Andean Plateau, as well as ...
Subsurface architecture of Las Bombas volcano circular structure (Southern Mendoza, Argentina) from geophysical studies
(Pergamon-Elsevier Science Ltd, 2017-08)
The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large ...
Observed auroral ovals secular variation inferred from auroral boundary data
(MDPI, 2021-08)
We analyze the auroral boundary corrected geomagnetic latitude provided by the Auroral Boundary Index (ABI) database to estimate long-term changes of core origin in the area enclosed by this boundary during 1983–2016. We ...
MtCRE1-dependent cytokinin signaling integrates bacterial and plant cues to coordinate symbiotic nodule organogenesis in Medicago truncatula
(Wiley Blackwell Publishing, Inc, 2011-02)
Phytohormonal interactions are essential to regulate plant organogenesis. In response to the presence of signals from symbiotic bacteria, the Nod factors, legume roots generate a new organ: the nitrogen-fixing nodule. ...
