Ion acoustic instability triggered by finite amplitude polarized waves in the solar wind
(Blackwell Publishing Ltd, 2005)
[1] It is shown that ion-acoustic waves propagating along an external magnetic field and
generated by parametric decays of circularly polarized finite amplitude waves have the
properties of ion-acoustic waves observed ...
Ion acoustic damping effects on parametric decays of Alfvén waves: Right-hand polarization
(Blackwell Publishing Ltd, 2001)
We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
Geodynamic conditions resulting from the 2010 earthquake and tsunami in the coast of central Chile. The case of Pichilemu Condiciones geodinámicas derivadas del terremoto y tsunami de 2010 en la costa de Chile central. El caso de Pichilemu
(Revista de Geografia Norte GrandeAvda.Vicuna Mackenna 4860Macul-Santiago, 2015)
© 2015, Revista de Geografia Norte Grande, All rights reserved.The earthquake and tsunami of 2010, triggered changes in the geomorphological and sedimentary dynamics along the coast of Pichilemu, in central Chile. These ...
Observed and predicted climate variability and climate change in the Altiplano of northern Chile Variabilidad y cambios climáticos observados y esperados en el altiplano del norte de Chile

© 2015, Revista de Geografia Norte Grande. All rights reserved.This study analyses temperature, rainfall irregularity and droughts in the Altiplano of Northern Chile at different temporal and spatial scales using data from ...
Seasonal variation in some reproductive parameters of male vicunña in the high andes of northern chile
(1994)
Experiments were undertaken to obtain information on the effects of season on endocrine function and testicular morphology in male vicunña. Serial blood samples were taken every 15 min over 4-8 h in February and August: ...

©2016. American Geophysical Union. All Rights Reserved. The Unsolved Problems of Magnetospheric Physics Workshop was held in September 2015 in Scarborough, UK. In contrast to most other meetings, people were specifically ...
Pollen limitation and spatial variation of reproductive success in the insect-pollinated shrub Chuquiraga opposotifolia (Asteraceae) in the Chilian Andes
(2006)
Low temperatures, short growing seasons, and strong winds, which constrain the abundance and activity of insect pollinators, characterize alpine ecosystems. In northern hemisphere alpine environments, the reproductive ...
Luminescent nano-composites generated from a spray
(Elsevier B.V., 2008-11-01)
The spray-pyrolysis (SP) synthesis technique has been employed to obtain SiO2:Eu3+ and gamma-AlOOH:Eu3+, It was possible to obtain sub-micrometric spherical particles of SiO2 with luminescent Eu3+ ions bonded to the silica ...
Frequency upconversion properties of Tm3+ doped TeO2-ZnO glasses containing silver nanoparticles
(Elsevier B.V. Sa, 2012-09-25)
Frequency upconversion (UC) properties of Tm3+ doped TeO2-ZnO glasses containing silver nanoparticles (NPs) were investigated. Infrared-to-visible and infrared-to-infrared UC processes associated to the Tm3+ ions were ...
Nanocompósitos cerâmicos a partir do processo de moagem mecânica de alta energia
(Sociedade Brasileira de Química, 2008-01-01)
Pb/Ti, Sn and Mg-based nanocomposite materials were prepared by the high-energy mechanical milling of commercial powders. The surface of these ceramic compounds was strongly influenced by the doping, diameter of the milling ...
