An interspecific Gossypium hirsutum x Gossypium barbadense backcross population of 75 BC1 plants was evaluated for 1014 markers. The map consists of 888 loci, including 465 AFLPs, 229 SSRs, 192 RFLPs, and 2 morphological markers, ordered in 37 linkage groups that represent most if not all of the 26 chromosomes, altogether spanning 4400 cM. Loci were not(More)
Microsatellite markers or simple sequence repeats (SSRs) represent a new class of genetic markers for cotton (Gossypium sp.). Sixty-five SSR primer pairs were used to amplify 71 marker loci and genotype 13 monosomic and 27 monotelodisomic cotton cytogenetic stocks. Forty-two SSR loci were assigned to cotton chromosomes or chromosome arms. Thirty SSRs were(More)
Lime (calcium hydroxide) was used as a pretreatment agent to enhance the enzymatic digestibility of switchgrass. After studying many conditions, the recommended pretreatment conditions are: time = 2 h, temperature = 100 degrees C and 120 degrees C, lime loading = 0.1 g Ca(OH)(2)/g dry biomass, water loading = 9 mL/g dry biomass. Studies on the effect of(More)
Physical solvents such as DEPG (SelexolTM or Coastal AGR), NMP or N-Methyl-2Pyrrolidone (Purisol), Methanol (Rectisol), and Propylene Carbonate (Fluor SolventTM) are becoming increasingly popular as gas treating solvents, especially for coal gasification applications. Physical solvents tend to be favored over chemical solvents when the concentration of acid(More)
Simultaneous saccharification and fermentation (SSF) was performed on lime-treated switchgrass and corn stover, and oxidatively lime-treated poplar wood to determine their compatibility with Saccharomyces cerevisiae. Cellulose-derived glucose was extensively utilized by the yeast during SSF. The ethanol yields from pretreated switchgrass, pretreated corn(More)
We demonstrate the hohlraum radiation temperature and symmetry required for ignition-scale inertial confinement fusion capsule implosions. Cryogenic gas-filled hohlraums with 2.2 mm-diameter capsules are heated with unprecedented laser energies of 1.2 MJ delivered by 192 ultraviolet laser beams on the National Ignition Facility. Laser backscatter(More)
Ignition implosions on the National Ignition Facility [J. D. Lindl et al., Phys. Plasmas 11, 339 (2004)] are underway with the goal of compressing deuterium-tritium fuel to a sufficiently high areal density (ρR) to sustain a self-propagating burn wave required for fusion power gain greater than unity. These implosions are driven with a very carefully(More)
