A series of experiments are reported which serve as milestones in the development of the MPFD technology. Each test involved reactor pulsing, a controlled power excursion that results from rapid removal of control rods. During a reactor pulse, the po

An updated method of preparing thin, uranium-coated, 0.25-mm diameter platinum electrodes using the cyclic potential sweep method is described. Sixty-four samples were prepared using a 0.2 M UO2(NO3)2 solution with 19.695% enriched uranium. Improveme

Rate coefficients (\ensuremath{\alpha}${}_{\mathrm{D}}$) for the dissociative recombination of ${\mathrm{Ar}}_{2}$${}^{+}$ and N${}_{4}$${}^{+}$ in low-temperature plasmas have been determined by multiphoton ionization of the parent gas (Ar or N${}_{

Lasing at both 589.0 nm and 589.6 nm in Na has been realized by photoassociating Na-rare gas pairs.

Pumping the Cs 852.1nm laser by photoassociating Cs-rare gas atomic pairs allows one to observe a four-level system morph into a two-level system. This occurs when the state 3-state 2 energy defect falls below ∼2kT/3.

As part of ongoing studies regarding the genetic basis of quantitative variation in phenotype, we have determined the chromosomal locations of quantitative trait loci (QTLs) affecting fruit size, soluble solids concentration, and pH, in a cross betwe
