    The Microstructure of Pure Copper after Stepwise Change of Irradiation Temperature (2005)
    s.l. ; Stafa-Zurich, Switzerland
    Materials science forum Vol. 475-479 (Jan. 2005), p. 1479-1482 
    Details
    ISSN: 1662-9752
    Source: Scientific.Net: Materials Science & Technology / Trans Tech Publications Archiv 1984-2008
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: In order to investigate the effect of stepwise change of irradiation temperature on pure copper, heavy ion irradiations under constant temperature and varying temperature conditions were performed. Specimens were irradiated up to 10dpa. In the temperature region of 473K ~ 673K, one-step temperature variation and periodic temperature variations were performed during irradiation. The resulting microstructures were compared with those induced by the irradiation at the constant temperature of 673K

    Molecular analysis of the gene cluster involved in cephalosporin biosynthesis from Lysobacter lactamgenus YK90 (1996)
    Springer
    Applied microbiology and biotechnology 44 (1996), S. 589-596 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Determination of the nucleotide sequence downstream from the Lysobacter lactamgenus pcbC gene encoding isopenicillin N synthase revealed that five open-reading frames (ORF) including the pcbC gene were tightly linked in the same orientation. Each ORF has the remarkable feature of the protein-coding frame in the DNA sequence with a high G + C content. Expression in Escherichia coli and a comparison of the deduced amino acid sequences with published sequences showed that the gene cluster contained a deacetoxycephalosporin C synthetase (DAOCS) gene (cefE), an ORF having homology with the Cephalosporium acremonium DAOCS/deacetylcephalosporin C synthetase gene (cefEF), an isopenicillin N epimerase gene(cefD), and a β-lactamase gene. The gene order was pcbC-cefE-ORF3-cefD-β-lactamase.

    Organization and expression in Pseudomonas putida of the gene cluster involved in cephalosporin biosynthesis from Lysobacter lactamgenus YK90 (1996)
    Springer
    Applied microbiology and biotechnology 45 (1996), S. 490-501

    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract  The Lysobacter lactamgenus YK90 pcbAB gene encoding δ-(L-α-aminoadipyl)-L-cysteinyl-D-valine (ACV) synthetase is located immediately upstream of the pcbC gene in the same orientation in the gene cluster involved in cephalosporin biosynthesis. The pcbAB gene encodes a large polypeptide composed of 3722 amino acid residues with a molecular mass of 411593 Da. The predicted amino acid sequence has a high degree of similarity with those of known ACV synthetases from fungi and actinomycetes. Within the pcbAB amino acid sequence, three conserved and repeated domains of about 600 amino acids were identified. The domains also share a high degree of similarity with non-ribosomal peptide synthetases such as gramicidin synthetase 2 of Bacillus brevis. The pcbAB gene was expressed under the control of the lac promoter in Pseudomonas putida. Expression of the gene cluster involved in cephalosporin biosynthesis in P. putida led to the accumulation of β-lactam antibiotics. Deletion analysis of an open-reading frame located between the cefE and cefD genes from the gene cluster revealed that it encoded deacetylcephalosporin C synthetase (cefF). From the results presented here and those of previous studies, the genes involved in cephalosporin biosynthesis in L. lactamgenus appear to be clustered in the order pcbAB-pcbC-cefE-cefF-cefD-bla in the same orientation within a 17-kb region of DNA.

    Top-Antitop Pair Production Close to Threshold Synopsis of Recent NNLO Results (2000)

    Notes: Abstract Using non-relativistic effective theories, new next-to-next-to-leading order (NNLO) QCD corrections to the total $$t{\bar t}$$ production cross section at the Linear Collider have been calculated recently. In this article the NNLO calculations of several groups are compared and the remaining uncertainties are discussed. The theoretical prospects for an accurate determination of top quark mass parameters are discussed in detail. An outlook on possible future improvements is given.

    Comparing the QCD potential in perturbative QCD and lattice QCD at large distances (2003)
    Springer
    The European physical journal 31 (2003), S. 187-196

    Notes: Abstract. We compare the perturbatively calculated QCD potential to that obtained from lattice calculations in the theory without light quark flavours. We examine E tot(r) = 2 m pole + V QCD(r) by re-expressing it in the $\overline{\mathrm {MS}}$ mass $\overline{m} \equiv m^{\raisebox{-1pt}{$\scriptstyle\overline{\mathrm{MS}}$}}(m^{\raisebox{-1pt}{$\scriptstyle\overline{\mathrm{MS}}$}})$ and by choosing specific prescriptions for fixing the scale μ (dependent on r and $\overline{m}$ ). By adjusting $\overline{m}$ so as to maximise the range of convergence, we show that perturbative and lattice calculations agree up to $3 r_0\simeq 7.5 {\mathrm {GeV}}^{-1}$ (r 0 is the Sommer scale) within the uncertainty of order $\Lambda_{\mathrm{QCD}}^3 r^2$ .
