| With the collisional history of Mars, you're dealing with a history of billions of years. |
|
| It has a sinuous outcrop caused by collisional indentation of one block into another. |
|
| Such excitation leads not only to collisional de-excitation of excited atoms but also to additional excitation of excited atoms. |
|
| The collisional thermalization between electrons and ions is very slow, due to the large difference in their masses, and it occurs on a millisecond timescale. |
|
| The theoretical difficulty lies in the fact that the plasma is weakly collisional, a field of plasma physics that is still not well understood. |
|
| The uncertainty budget is nearly complete, with work progressing on the collisional frequency shift. |
|
| We also introduce collisional phenomena such as thermal diffusion and heat-exchange between ions and electrons. |
|
| Almost all meteorites are collisional fragments of asteroids, and can be dated radiometrically to about 4.6 billion years, which represents the birth of the Solar System. |
|
| This in turn is followed by the development of collisional environments that become increasingly important with time. |
|
| A universal collisional activation ion trap for use in mass spectrometry comprising an ion trapping means having connected thereto a random noise signal generator, said ion trapping means containing a bath gas. |
|
| Thanks to the calculations already made, it appeared that it was necessary to make numerous simulations of the movement of the Solar System over 5 Gyr, because the estimated probability of collisional events was low. |
|
| Regional relationships and fieldwork near the mining district, along with geomechanical reasoning, are the basis for making a detailed reconstruction of the events leading up to, and during, collisional orogenesis. |
|
| We report on new level-resolved calculations for the dielectronic recombination and collisional excitation of the low charge states of argon. |
|
| Case studies on the anatomy, textures and magmatichydrothermal evolution of ore-bearing granitic systems in rare-metal provinces of Eurasia that are related to collisional orogens have been continued towards their completion. |
|
| The nebular temperature can be estimated directly from collisional lines alone by comparing emission lines from high-energy levels, populated by collisions, with lines from lower levels. |
|
| In addition, new collisional events led to the formation of Gondwana, a supercontinent composed of what would become Australia, Antarctica, India, Africa, and South America. |
|
| This collisional event is particularly important because welding the cratons together provided the core of Laurentia, the continent that was ultimately to become North America. |
|
| Study of the collage and collisional tectonics in the Red Indian Line, central Newfoundland, a segment of the Iapetus suture zone, the fundamental tectonic boundary of the Appalachian-Caledonide orogen. |
|
| Since then he has been involved in over 100 publications on Namibian geology, most notably editing a publication and map on the Pan African collisional Damara Orogen. |
