Boron Enrichment in Martian Clay
We have detected a concentration of boron in martian clay far in excess of that in any previously reported extra-terrestrial object. This enrichment indicates that the chemistry necessary for the formation of ribose, a key component of RNA, could have existed on Mars since the formation of early clay deposits, contemporary to the emergence of life on Earth. Given the greater similarity of Earth...

15 صفحه اولMechanical interaction between swelling compacted clay and fractured rock, and the leaching of clay colloids
We consider the interaction between a saturated clay buffer layer and a fractured crystalline rock engineered disturbed zone. Once saturated, the clay extrudes into the available rock fractures, behaving as a compressible nonNewtonian fluid. We discuss the modelling implications of published experiments carried out in Sweden and more recently in Japan. Extrusion is halted either when the advanc...
متن کاملClay-shoveler's fracture during indoor rock climbing.
Indoor rock climbing is becoming more popular for people of all ages. Despite the tremendous interest in this competitive sport, participants are made aware of the dangers associated with participating. The authors present the first reported case of a clay-shoveler's fracture at the T1 spinous process during indoor rock climbing. They describe the management and natural history of this fracture...
متن کاملDesorption of arsenic from clay and humic acid-coated clay by dissolved phosphate and silicate.
Arsenic (As) contaminated aquifers contain iron minerals and clays that strongly bind As at their surfaces. It was suggested that As mobilization is driven by natural organic matter (including fulvic acids (FA) and humic acids (HA)) present in the aquifers either via providing reducing equivalents for reductive dissolution of Fe(III) (hydr)oxides or via competitive desorption of As from the min...
