After the Second World War, British state became interested in potential of wind as an energy source. Over a period twenty years, from mid-1930s to mid-1950s, scientific and non-scientific communities surveyed airspaces landscapes produce first national survey Britain. This work informed development siting turbine connected public electricity supply, Orkney, Scotland, 1951. Meteorologists, phys...

This paper considers two similar graph algorithms that work by repeatedly increasing “flow” along “augmenting paths”: the Ford-Fulkerson algorithm for the maximum flow problem and the Gale-Shapley algorithm for the stable allocation problem (a many-to-many generalization of the stable matching problem). Both algorithms clearly terminate when given integral input data. For real-valued input data...

We studied the UDP-glucose pyrophosphorylase (galU) and UDP-galactose epimerase (galE) genes of Lactococcus lactis MG1363 to investigate their involvement in biosynthesis of UDP-glucose and UDP-galactose, which are precursors of glucose- and galactose-containing exopolysaccharides (EPS) in L. lactis. The lactococcal galU gene was identified by a PCR approach using degenerate primers and was fou...

This work aimed to establish the role of gne (encoding UDP-GalNAc 4-epimerase activity) and galE (encoding UDP-Gal-4-epimerase activity) in the biosynthesis of surface polysaccharides, as well as in the virulence for eels and humans of the zoonotic serovar of Vibrio vulnificus biotype 2, serovar E. DNA sequence data revealed that gne and galE are quite homologous within this species (> or =90% ...

The capR (lon) product controls expression of the gal operon independently of the galR repressor. Previously, mutations of the gal operon have been isolated that are semiconstitutive and alter response to the capR and/or capT product. Such mutants imply the existence of a distinct site in the operon that responds to capR (capT) control. This mutation could be either in a site near the operator-...

SCHWINTZER, C. R. 1983. Primary productivity and nitrogen, carbon, and biomass distribution in a dense My)-ica gale stand. Can. J. Bot. 61: 2943-2948. Aboveground vascular vegetation was harvested in twenty 0.25-m' plots at the end of the growing season in a weakly minerotrophic, central Massachusetts peatland. The materials were separated by species and component and the Myrica gale fractions ...

New results on a class of distributed two-sided matching algorithms are described. In particular, these algorithms can dominate the matches produced by the Gale-Shapley algorithm in terms of both average social welfare and fairness. However, stability is not guaranteed and therefore a natural tradeoff arises between stability and social welfare. At one extreme, stability is ‘purchased’ in Gale-...

Pathogenic meningococci have acquired a 24 kb capsule synthesis island (cps) by horizontal gene transfer which consists of a synthetic locus and associated capsule transport genes flanked by repetitive Regions D and D'. Regions D and D' contain an intact gene encoding a UDP-galactose epimerase (galE1) and a truncated remnant (galE2), respectively. In this study, GalE protein alleles were shown ...
