USE OF COPPER SLAG AS FINE AGGREGATE AND PARTIAL REPLACEMENT OF CEMENT

Holos, 2018
Estuda-se o uso de escória de cobre (CS) como agregado fino e substituto parcial do cimento na preparação de argamassas. Os resultados mostraram um aumento na resistência à compressão e à flexão em 3, 7 e 28 dias usando CS como agregado fino.

Optical modeling and polarization calibration for CMB measurements with ACTPol and Advanced ACTPol

, 2016
The Atacama Cosmology Telescope Polarimeter (ACTPol) is a polarization sensitive upgrade to the Atacama Cosmology Telescope. Located at an elevation of 5190 m, ACTPol measures the Cosmic Microwave Background (CMB) temperature and polarization with ...

Empirical Scaling Relationships Between Fault Length and Throw‐Rates Modulated by Fault Interactions in Extensional Regimes

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Throw rates of active faults are expected to scale with fault length because the geometric moment of a fault is directly related to its dimensions. However, empirical data sets commonly display substantial scatter, which limits the use of fault scaling relationships for seismic hazard assessment and for understanding the mechanics of ...

The effect of terrestrial weathering on the mineralogy and petrologic (sub)types of CM chondrites explored by kinetic modeling and laboratory experiments

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 874-897, May 2026.
Abstract Terrestrial weathering alters the chemical and isotopic composition, and mineralogy, of meteorites; its effects on ordinary chondrites are well‐studied, but relatively little is known about the susceptibility of carbonaceous chondrites. We combined laboratory experiments, whereby Chwichiya 002 (C3‐ung find), Murchison (CM2 fall) and Kolang ...

THE BOUNCING BOULDERS OF THE ATACAMA

, 2020
124 pages ; In the heart of Chile’s Atacama Desert thousands of boulders, some exceeding 5 m in diameter, lie at the bases of steep escarpments. The rapid and forceful descents of the boulders are commonly recorded by the trails of small impact craters the boulders left as they bounced down the escarpments.

Evaporation in the Atacama Desert

, 2022
Understanding evaporation in arid regions is essential for climate change assessment and optimizing water resources management under a changing climate. This thesis analyses the physical processes that govern local evaporation in a representative salt flat setting at the Altiplano region of the Atacama Desert.

Atacama. Ocupación actual del desierto y del semidesierto de Chile

Estudios Geográficos, 2009
Estos espacios representan el 40% del territorio nacional, pero sólo un 12% de la población; aportan 15% del PIB. El desierto es de una aridez extrema y sus principales riquezas económicas están en la minería; estos factores inciden en la ocupación ...
