Dinâmica ressonante de alguns satélites artificiais terrestres no sistema Terra-Lua-Sol
(Universidade Estadual Paulista (UNESP), 2014)
Post space cleaning using a new nickel titanium endodontic drill combined with different cleaning regimens
(ELSEVIER SCIENCE INC, 2008)
This study compared the effect of two drills and five cleaning regimens on post space debridement. One hundred extracted premolars were instrumented and obturated with warm vertical compaction of gutta percha. The teeth ...
Dynamic implications of ridges on a debris avalanche deposit at Tutupaca volcano (southern Peru)
(Springer Berlin HeidelbergDE, 2016-02)
Catastrophic volcanic landslides can involve different parts of a volcano that can be incorporated into any resulting debris avalanche. The different material properties may influence the mechanical behaviour and, hence, ...
A Dusty Component to the Gaseous Debris Disk Around the White Dwarf SDSS J1228+1040
(2009)
We present ISAAC spectroscopy and ISAAC, UKIDSS and Spitzer Space Telescope broad-band photometry of SDSS J1228+1040 -- a white dwarf for which evidence of a gaseous metal-rich circumstellar disk has previously been found ...
A direct imaging survey of spitzer-detected debris disks: occurrence of giant planets in dusty systems
(IOP Publishing Ltd., 2017)
We describe a joint high-contrast imaging survey for planets at the Keck and Very Large Telescope of the last large sample of debris disks identified by the Spitzer Space Telescope. No new substellar companions were ...
Stellar multiplicity and debris discs: an unbiased sample
(Oxford University Press, 2015)
Circumstellar dust discs have been observed around many nearby stars. However, many
stars are part of binary or multiple stellar systems. A natural question arises regarding the
presence and properties of such discs in ...
Modelling the inner debris disc of HR 8799
(2016-11-21)
In many ways, the HR 8799 planetary system strongly resembles our own. It features four giant planets and two debris belts, analogues to the Asteroid and Edgeworth-Kuiper belts. Here, we present the results of dynamical ...
Seasonal flooding, topography, and organic debris interact to influence the emergence and distribution of seedlings in a tropical grassland
(Wiley-Blackwell, 2018-07-01)
In seasonally flooded wetlands, inundation and associated organic debris deposition followed by a drawdown period can promote plant community diversity across space and time. Post-flood regeneration might be influenced by ...
Modeling of debris disks in single and binary stars
(Universidad Nacional Autónoma de México, 2016-10)
Infrared space observatories such as Spitzer and Herschel have allowed the detection of likely analogs to the Kuiper Belt in single as well as binary systems. The aim of this work is to characterize debris disks in single ...
