Hemicellulose hydrolysates of the agricultural residues bagasse, corn stover, and corn hulls plus fibers were readily fermented to ethanol by recombinantEscherichia coli strain KO11. Corn steep liquor and crude yeast autolysate served as excellent nutrients. Fermentations were substantially complete within 48 h, often achieving over 40 g ethanol L−1.(More)
This study presents a new empirical model to estimate the base shear of plane steel structures subjected to earthquake load using a hybrid method integrating genetic programming (GP) and simulated annealing (SA), called GP/SA. The base shear of steel frames was formulated in terms of the number of bays, number of storey, soil type, and situation of braced(More)
Karyological study of four Agropyron species (A. desertorum, A. cristatum, A. pectinoforum and A. imbricatum) showed that these species were tetraploid (2n = 4x = 28) with the base number, x=7. In the studied cells ofA. desertrum, 28 chromosomes with 1 B chromosome and satellite on chromosomes 2 and 4 were exist. The number of chromosomes in studied cells(More)
This paper presents a new nonlinear model for the prediction of hysteretic energy demand in steel moment resisting frames using an innovative genetic-based simulated annealing method called GSA. The hysteretic energy demand was formulated in terms of several effective parameters such as earthquake intensity, number of stories, soil type, period, strength(More)
