Lithium intercalation into double rare earth chromates was carried out. It was found that the compounds NaxLi1-xLa(CrO4)2 belong to the NaLa(CrO4)2 structural type and may be recommended as fast ionic conductors. At small ...

The campos de murundus (literally “mound fields”) are intriguing landscapes composed of earth-mounds. These microreliefs occur in transition areas between the plateau and hydromorphic areas of the Brazilian Savanna. Several ...

In an effort to calibrate assessment methods of existing earth structures, a new database with compression and bending tests on unbaked earth specimens was assembled. The data-collection database includes 2670 tests with ...

It is undeniable that earth architecture is found in all the regions and civilizations of the world, Fig. 1, strongly rooted in the culture of each town and popular knowledge of each region, being evidence of this the city ...

This contribution deals with fast Earth–Moon transfers with ballistic capture in the patched three-body model. We compute ensembles of preliminary solutions using a model that takes into account the relative inclination ...

The alkaline earth tricyanomethanides Mg(tcm)(2) center dot 2H(2)O, Ca(tcm)(2), Sr(tcm)(2) - H2O and Ba(tcm)(2) center dot 2H(2)O were prepared from aqueous solutions of the respective chlorides and silver tricyanomethanide. ...

Observations of the performance of basement walls and retaining structures in recent earthquakes show that failures of basement or deep-excavation walls in earthquakes are rare even if the structures were not designed for ...
