    Notes: Abstract —Geological investigations of coastal sediments indicate that prehistoric tsunamis can be identified. Their characterisation has altered our knowledge of the past frequency and magnitude of tsunamis for different areas of the world. Yet there have been relatively few geological studies of modern tsunamis with virtually no direct observations of the processes associated with tsunami sediment transport and deposition. This paper discusses these issues and draws on the results of recent research to summarise our current knowledge on the nature of tsunami deposits.

    Notes: Abstract  N2O emission from a wetland rice soil as affected by the application of three controlled-availability fertilizers (CAFs) and urea was investigated through a pot experiment. N2O fluxes from the N fertilized paddy soil averaged 44.8–69.3 μg N m–2 h–1 during the rice growing season, accounting for 0.28–0.51% of the applied N. The emission primarily occurred during the mid-season aeration (MSA) and the subsequent re-flooding period. Fluxes were highly correlated with the NO3 – and N2O concentrations in the soil water. As there were relatively large amounts of NH4 +-N present in the soil of the CAF treatments at the beginning of MSA, leading to large amounts of NO3 –-N during the MSA and the subsequent re-flooding period, the tested CAFs were not effective in reducing N2O emission from this paddy soil. The potential of applied CAFs to reduce N2O emissions from paddy soil is discussed.

    Phylogenetic relationships of the Magnoliaceae inferred from cpDNA matK sequences (2000)
    Springer
    Theoretical and applied genetics 101 (2000), S. 925-930 
    Details
    ISSN: 1432-2242
    Keywords: Key words Magnoliaceae ; Molecular phylogeny ; Chloroplast DNA ; matK gene
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract  The coding region of the matK gene was sequenced to infer the phylogeny of the family Magnoliaceae. Phylogenetic analyses of 21 matK sequences representing ten genera of Magnoliaceae and three outgroups suggest relationships among both subfamilies and genera. Monophyly of the subfamily Liriodendroideae (the genus Liriodendron) and the subfamily Magnolioideae is strongly supported, respectively. Within the subfamily Magnolioideae, three clades are formed: (1) the genus Magnlietia, (2) the subgenus Magnolia, and (3) the subgenus Yulania, with the genera Michelia, Paramichelia, Tsoongiodendron, Alcimandra, Kmeria, Parakmeria and Manglietiastrum. However, the genus Magnolia is shown to be a polyphyletic group, and the genus Michelia a paraphyletic group. Relatively low sequence divergences are detected among genera of the the subfamily Magnolioideae, ranging from 0.14% to 1.70%, especially in the tribe Micheliinae (0.14–0.98%). Molecular evidence from matK sequence data suggests that the phylogenetic positions and the delimitation of the eight genera Magnolia, Michelia, Tsoongiodendron, Paramichelia, Alcimandra, Kmeria, Parakmeria and Manglietiastrum need to be reconsidered.

    Simulation of Sub-harmonic SIS Mixers with a Full Five-Port Model (2000)
    Springer
    International journal of infrared and millimeter waves 21 (2000), S. 921-929 
    Details
    ISSN: 1572-9559
    Keywords: sub-harmonic SIS mixer ; full five-port model ; quasi five-port model
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The performance of superconductor-insulator-superconductor (SIS) sub-harmonic mixers is thoroughly investigated in this paper. On account of the importance of the harmonic effect, a full five-port model combined with an enhanced Newton solution is applied to calculate the local oscillator (LO) waveform. The mixer performance is studied as functions of principal parameters including the embedding admittances, LO power and bias voltage. The results are compared with those from the quasi five-port model.

    Advanced primary treatment of waste water using a bio-flocculation-adsorption sedimentation process (2000)
    Berlin : Wiley-Blackwell
    Acta Biotechnologica 20 (2000), S. 53-64

    Notes: An advanced primary treatment process for a municipal waste water was systematically studied, using a bio-flocculation-adsorption, sedimentation and stabilzation process (BSS). It was shown that the organic removal efficiency was higher than that of the traditional primary treatment processes but lower than that of the traditional secondary treatment processes. Both adsorption and bio-flocculation played an important role in the removal of pollutants. The activated sludge within the bio-flocculation-adsorption tank could be considered a bio-flocculent which improved the quality of the effluent from the primary treatment process. As the effluent of the BSS process did not meet the requirements for a typical secondary effluent, the process may be regarded as an advanced (or enhanced) primary treatment process, suitable for waste water containing a high concentration of suspended solids and colloidal particles.
