Development of advanced NO sub x control concepts for coal-fired utility boilers
CombiNO{sub x} is an integration of three technologies: modified reburning, promoted selective noncatalytic reduction (SNCR) and methanol injection. These technologies are combined to achieve high levels of NO{sub x}, emission reduction from coal fired power plants equipped with SO{sub 2} scrubbers. The first two steps, modified reburning and promoted SNCR are linked. It has been shown that, performance of the SNCR agent is dependent upon local oxidation of CO. Reburning is used to generate the optimum amount of CO to promote the SNCR agent, although lower levels of reburning are needed than are traditionally applied in the reburning process. If the reburn fuel is natural gas, the combination of reburning and SNCR may result in a significant cost savings over conventional reburning. The third step, injection of methanol into the flue gas, is used to convert NO to NO{sub 2} which may subsequently be removed in a wet scrubber.

Characterization of muntjac DNA
Sister chromatid exchange (SCE) in muntjac chromosomes is generally proportional to the chromosomal DNA content, but the SCE frequency is reduced in the heterochromatic neck region of the X chromosome. The physical properties of muntjac DNA and the kinetics of repair of UV damage in muntjac heterochromatin and euchromatin were examined and compared with the distribution of sister chromatid exchange.

Symmetry issues in a class of ion beam targets using short direct drive pulses
We address a class of modified ion beam targets where the symmetry issues are ameliorated in the regime of short bursts of direct drive pulses. Short pulses are here defined so that the fractional change in target radii of peak beam energy deposition are assumed to be small (during each such direct drive burst with a fixed beam focal radius). This requirement is actually not stringent on the temporal pulse-length. In fact we show an explicit example where this can be satisfied by a greater than or equal to 60 ns direct drive pulse-train. A new beam placement scheme is used which systematically eliminated low order spherical harmonic asymmetries. The residual asymmetries of such pulses are studied with both simple model and numerical simulations.
