Carbon monoxide hydrogenation over alkali-promoted Rh/Al2O3, Rh/V2O3/SiO2 and Rh/ThO2/SiO2
Addition of Li, Na, K and Cs to a 1.5 wt% Rh/Al,O, catalyst resulted in a decrease of the hydrocarbon formation rate, while the methanol formation rate was almost unaffected. The overall result is an increased oxygenate selectivity at a decreased total activity. The oxo-selectivity increased in the order unpromoted < Li < Na< K < Cs. The results suggest that the main role of the alkali promoter...
متن کاملRh Incompatibility in Pregnancy
Rh incompatibility [4] occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus [5], leading to the mother?s development of Rh antibodies. These antibodies have the potential to cross the placenta [6] and attach to fetal red blood cells, resulting in hemolysis, or destruction of the fetus?s red blood cells. This causes the fetus [5] to become a...

متن کاملType IIB RH Conjectures
We propose SL(2, Z) (and SL(3, Z)) invariant conjectures for all RH couplings of Type IIB strings on R (and R8×T ), generalizing conjectures of Green and Gutperle (and Kiritsis and Pioline) for the R coupling. A strong check for our conjectures is that on T 2 at weak coupling, they reproduce the multiloop scattering amplitudes which had been previously computed using N = 2 strings in the N = 4 ...
