Flux and provenance of ice-rafted debris in the earliest Pleistocene sub-polar North Atlantic Ocean comparable to the last glacial maximum
(Amsterdam, 2012-07-13)
Relatively little is known in detail about the locations of the early Pleistocene ice-sheets responsible for ice-rafted debris(IRD) inputs to the sub-polar North Atlantic Ocean during intensification of northern hemisphere ...
Estudo de manobras evasivas com perturbações orbitais

Granular fingering as a mechanism for ridge formation in debris avalanche deposits: Laboratory experiments and implications for Tutupaca volcano, Peru
(ElsevierNL, 2018-01)
The origin of subparallel, regularly-spaced longitudinal ridges often observed at the surface of volcanic and other rock avalanche deposits remains unclear. We addressed this issue through analogue laboratory experiments ...
Revitalização do ambiente construído com a utilização de resíduos de demolição: um estudo de caso
(Universidade Federal de Minas GeraisUFMG, 2011-03-02)
The economic growth and demographic expansion of cities has caused an upturn in the construction industry, producing large amounts of debris that add to municipal waste being collected and sent to landfills. With the growth ...
Efeitos do hipoclorito de cálcio sobre a interface de adesão do sistema de cimentação de pinos de fibra na dentina radicular
(Universidade Estadual Paulista (Unesp), 2018-03-13)
O objetivo do presente estudo foi avaliar os efeitos dos protocolos de irrigação com o hipoclorito de cálcio (CH) ou sódio (SH), por meio do método convencional (CI) ou através da irrigação ultrassônica passiva (PUI), sobre ...
The age structure of the Milky Way's halo
(2016)
We present a new, high-resolution chronographic (age) map of the Milky Way's halo, based on the inferred ages of similar to 130,000 field blue horizontal-branch (BHB) stars with photometry from the Sloan Digital Sky Survey. ...
Método para la predicción temporal de avenidas torrenciales a partir de datos abiertos usando aprendizaje de máquinas
(Universidad Nacional de ColombiaMedellín - Minas - Maestría en Ingeniería - AnalíticaDepartamento de la Computación y la DecisiónFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2022)
Las avenidas torrenciales son fenómenos destructivos característicos de regiones montañosas. En el departamento de Antioquia (Colombia), estos eventos ocurren con frecuencia y las pérdidas en términos económicos y de vidas ...
A semi-analytical approach to study resonances effects on the orbital motion of artificial satellites
(2013-01-01)
A semi-analytical approach is proposed to study resonances effects on the orbital motion of artificial satellites or space debris orbiting the Earth. Applying successive Mathieu transformations, the order of dynamical ...
Detritos espaciais: análise da ressonância 1:3 e a perturbação lunar
(Universidade Estadual Paulista (Unesp), 2018-11-29)
This work analyses the dynamical behavior near the 1 : 3 tesseral resonance. The system is formed by the Earth, and its gravity coefficients J2, J3 and C22, a sample of space debris and the Moon. In order to perform this ...
