In this paper, we diaspore weight and shape of 78 species (23 seeds, 55 fruits) in the Horqin Steppe. Horqin Steppe, located in the semiarid agropastoral zone of northern China, has undergone severe desertification during the past decades with the formation of active dunes, degeneration of natural vegetation, and loss of biodiversity.

A review of pretreatment of diasporic bauxite ores by ...

Diaspore, along with gibbsite and boehmite, is a major component of the aluminium ore bauxite. It was first described in 1801 for an occurrence in Mramorsk Zavod, Sverdlovskaya Oblast, Middle Urals, Russia. The name, which was coined by René Just Haüy, is from the Greek for διασπείρειν, to scatter, in allusion to its decrepitation ...
