Osborne, Rüdiger Schack Abstract We formulate and prove a de Finetti representation theorem for finitely exchangeable states of a quantum system consisting of k infinite dimensional subsystems. The theorem is valid for states that can be written as the partial trace of a pure state chosen from a family of subsets Cn of the full symmetric subspace for n subsystems.

Addition of young C to shells during diagenesis occurs in soil solution, where the Ca 2 concentration is in equilibrium with exchangeable Ca 2 and/or weathering of Ca bearing minerals. While the exchange process takes place within seconds, the dissolution equilibrium requires longer timescales on the order of months . It has therefore been hypothesized that the dissolution and recrystallization of shell carbonate in soils with higher ...

To explore the mechanisms of stability, 3D pore characteristics were analyzed with microtomography scans. Furthermore, the contents of carbon and exchangeable polyvalent cations as well as contact angles were determined. Results: Water stability of macroaggregates was much higher in the cropped plot geometric mean diameter 0.65 2.37 mm cropped vs. 0.31 0.56 mm BF , while mechanical stability was very similar median work 17.3 cropped a...

Fresh cassava yields ranged from 3.51 8.51, 13.52 25.84, and 16.92 30.98 t ha 1 at 12, 24, and 36 MAP, respectively. For every one unit increment in exchangeable K cmol /kg soil , cassava yield increased by 435, 268, and 406 kg ha 1 at 12, 24, and 36 MAP, respectively. One unit increment of magnesium cmol /kg soil gave the highest yield increase of 525 kg ha 1 at 24 MAP. The low levels of soil organic carbon explained the deficient ni...
