Organización del conocimiento y arquitectura de la información: tendencias y tensiones

Revista Ibero-Americana de Ciência da Informação, 2011
Las nociones de “conocimiento” e “información” siguen siendo tan polisémicas y de naturaleza tan abierta, que cada vez que se refiere a ellas, debería hacerse explícita la significación particular que adquieren en un contexto determinado.

Modern approaches to barium ore benefication

Записки Горного института
Barite is one of the critically important minerals in several industries, including the fuel and energy, nuclear, and medical sectors. For decades, its extraction did not require any complex techniques; however, with the depletion of rich barite-bearing ...

Flow-through experiments on the interaction of sandstone with Ba-rich fluids at geothermal conditions

Geothermal Energy, 2017
It is commonly known that heat extraction and decompression can lead to mineral precipitation and reservoir clogging in geothermal systems. In the Upper Rhine Graben, the precipitating minerals are mainly barite and calcite.
