Abstract: Systems and methods are provided for rendering content for presentation in a portion of a user interface based on context-independent data and a template that is selected based on context information associated with the user interface. The template may be selected from among a number of different templates based at least in part on a template selection data structure that associates each template with one or more combinations of contextual attributes associated with the context of the user interface. The content for inclusion in at least a portion of the user interface may then be rendered using the selected template and at least a portion of the context-independent data.

Abstract: The invention concerns a process for eliminating metallic impurities from magnesium, in particular iron, silicon and manganese.For that purpose, a halogenated derivative of boron such as BCl.sub.3 is injected into the molten magnesium, in a proportion of from 0.05 to 5 kg of pure boron per tonne of magnesium. The magnesium may first be subjected to a refining operation using TiCl.sub.4 or a mixture comprising TiCl.sub.4 +FeCl.sub.3.The magnesium produced contains less than 1 ppm of residual boron, less than 20 ppm of Fe and Si and less than 30 ppm of Mn.

Abstract: This invention relates to the thermal production of magnesium, using, as source of magnesium oxide, a residual slag from the manufacture of certain carbon-containing chrome irons and, as reducing agent, a ferro-silico-aluminum for carrying out the MAGNETHERM process. Magnesium is obtained with a high degree of purity and in excellent yields, with the recovery of a residual alloy containing chromium and silicon, and the production capacity of a given furnace is increased by about 16% compared with that obtained when using calcined dolomite.
