Bosek and Krawczyk exhibited an on-line algorithm for partitioning an on-line poset of width w into w lgw chains. They also observed that the problem of on-line chain partitioning of general posets of width w could be reduced to First-Fit chain partitioning of (2w + 1)-ladder-free posets of width w, where an m-ladder is the transitive closure of the union of two incomparable chains x1 6 . . . 6...

The Bio-Breeding/Worcester (BB/W) rat develops spontaneous autoimmune diabetes similar to human insulin-dependent diabetes mellitus. Transfusions of whole blood from the nondiabetic W-line of BB/W rats prevent the syndrome in diabetes-prone recipients. We report three experiments designed to determine which blood component is protective. In all experiments, diabetes-prone BB/W rats 23 to 35 d o...

objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...

bhw = half width of the line broadening, Å Eabs = integrated absorption energy,W=cm Eabs;p = absorption energy per particle, W Eemis = integrated emission energy,W=cm Eemis;p = emission energy per particle, W Eray = energy of a ray, photon bundle, W Fnum = Number of particles represented by a simulated particle i = cell index in the x direction j = cell index in the r direction k = line index k...

aqueous two-phase systems (atps) have  emerged as a powerful extraction method for the downstream processing of bio-molecules. the aim of this work was to investigate the possibility of utilizing atps for the separation of recombinant bacillus sphaericus phenylalanine dehydrogenase (phedh). polyethylene glycol (peg) and ammonium sulfate systems were selected for our experiment. the effect of di...

in this experiment 240 hy-line (w-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. the amounts of watermelon skin meal (wsm) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. the results showed that using wsm up to 2% significantly improved the performance and...

For arbitrary w : R → [0, 1] the general form of the continuous linear functionals on the space C 0 w of all functions f continuous on the real line, lim |x|→+∞ w(x)f (x) = 0 , equipped with seminorm ||f || w := sup x∈R w(x)|f (x)| , is found. The weighted analog of the Weierstrass polynomial approximation theorem and a new version of M.G. Krein's theorem about partial fraction decomposition of...
