, was amplified by polymerase chain reaction (PCR) and submitted to a conventional glass microchip analysis with a sieving matrix of 1.75% poly(vinylpyrrolidone) (M r 1 300 000), 1.0 % poly(ethyleneoxide) (M

soil located at Metaponto (South Italy). The "eld of 23�25 m was sampled in 81 sites at the nodes of a semi-regular grid and aggregate size distribution was obtained by dry sieving the soil through a nest of sieves (sized 10, 5, 2, 1 and 0)5 mm). The estimated D values were found to vary from 2

) marsh, and a freshwater managed (impounded) marsh, located in Sabine NWR, LA, using the sieving method. For the same marshes, we also provided an estimate of the readily germinable fraction of the seed bank using the germination method. Sieving results indicated that restored marsh edges had very low

. The identity of NAD+ kinase detected in the two fractions remains equivocal. NADH kinase was highly purified 1,041-fold from the mitochondrial fraction. The £ „ values for NADH and ATP were 106 /tM and 2.1 mM, respectively. The relative molecular mass was estimated to be 160,000 by means of molecular sieve

of randomized algorithms is to get a good estimate (upper bound, lower bound, or both) of Pr ( � i∈[m] Ei), for some given events Ei. Equivalently, a good lower bound, upper bound or both, is required for Pr ( � i∈[m] Ei). As we have seen, one approach would be to use the union bound (“counting sieve”), which

sieve-based estimator that is relatively simple to implement. The asymptotic properties of this estimator are derived and its finite-sample behavior is investigated through Monte Carlo simulations. An example of application to the relationship between earnings and divorce rates is also provided. * S. M

-iV-acetylgalactosaminidase preparation contained practically no other glycosidase activities except a-galactosidase activity, which amounted to 0.8% of the a-A'-acetylgalactosaminidase activity and may be an intrinsic activity of the enzyme. The molecular weight of the enzyme was estimated to be 80,000 at pH 4.2 and 40,000 at pH 7

by sieving them. Each fraction was cultured in both media and changes in the distribution of cells in the cluster fractions were followed during culture, after which the formation and dissociation rates of cells in aggregates were estimated. There was a significant difference in the formation
