High-resolution marine data and transient simulations support orbital forcing of ENSO amplitude since the mid-Holocene
(Elsevier, 2021)
Lack of constraint on spatial and long-term temporal variability of the El Niño southern Oscillation (ENSO) and its sensitivity to external forcing limit our ability to evaluate climate models and ENSO future projections. ...
Laboratory testing of the monotonic behavior of partially saturated sandy soil
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2010)
This paper presents a laboratory study on the influence of the saturation evaluated in term of Skempton's pore pressur coefficientBon the behavior of Chlef sand. The study is based on drained and unnonno drained compression ...

A study of the relative velocities of small particles that are orbiting the earth
(Univelt Inc, 2008-01-01)
The evolution of the velocity of the particles with respect to the circular orbits of satellites that are around the Earth that the particles will cross, suggests a range of possible velocities of impact as a function of ...
Trace elements, REEs and stable isotopes (B, Sr) in GAS groundwater, São Paulo State, Brazil
(2017-04-01)
This investigation was carried out in the Guarani Aquifer System (GAS) following a transect in São Paulo State, Brazil, and involved the analysis of trace elements, REEs and stable isotopes (B, Sr) in both rainwater and ...
Tunnelling in urban areas by epb machines: technical evaluation of the system
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2011)
The paper refers to the methods adopted for building a high-speed railway tunnel system between Bologna and Firenze (Italy), focusing attention on the Bologna node which represents the heart of the system, connecting the ...
Source mechanism of earthquake in Peru
(Springer, 2001-10)
The source mechanism of 19 earthquakes that occurred in Peru (1990–1996) is studied using broad band data. Focal mechanisms are obtained using polarities of P wave and body wave form inversion. Shallow earthquakes show ...
A new approach on the tectonometamorphic mechanisms associated with p–t paths of the barrovian-type silgará formation at the central santander massif, colombian andes
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2008)
Metamorphic pressure and temperature trajectories are generally used as tools to interpret the tectonic history ofdeformed belts of rocks that record past activity along active plate margins. The pre-Devonian metamorphic ...
