    Notes: The investigated material comprises rocks of the Palaeozoic ophiolitic assemblage exposed around the Sowie Góry Mountains Massif in the Sudetes in the form of the three units: ślza, Zαbkowice and Nowa Ruda. The radiometric age (U-Pb) of the rocks, stated as 420 ± 20 Ma, places them in the Silurian. A palaeomagnetic study reveals the presence of four groups of palaeomagnetic poles. One of these is derived from an isolated component representing Permian overprinting. The second remanence component fits with the Silurian results from Baltica and may therefore be regarded as being of Silurian age. According to this interpretation, the ophiolitic complex would not have been involved in tectonic action after Silurian times. On the other hand, this component does not agree with the results of the neighbouring Bohemian Massif but is consistent with Late Carboniferous data of the European Variscans. In this case the other two components should be interpreted as Early- to Mid-Carboniferous overprints. This interpretation implies important strike-slip movements. In order to exclude one of these hypotheses, more data are still needed.

    Receiver functions at the stations of the German Regional Seismic Network (GRSN) (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 121 (1995), S. 0

    Topics: Geosciences
    Notes: Several years of broad-band teleseismic data from the GRSN stations have been analysed for crustal structure using P-to-S converted waves at the crustal discontinuities. An inversion technique was developed which applies the Thomson-Haskell formalism for plane waves without slowness integration. The main phases observed are Moho conversions, their multiples in the crust, and conversions at the base of the sediments. The crustal thickness derived from these data is in good agreement with results from other studies. For the Gräfenberg stations, we have made a more detailed comparison of our model with a previously published model obtained from refraction seismic experiments. The refraction seismic model contains boundaries with strong velocity contrasts and a significant low-velocity zone, resulting in teleseismic waveforms that are too complicated as compared to the observed simple waveforms. The comparison suggests that a significant low-velocity zone is not required and that internal crustal boundaries are rather smooth.

    Comment on ‘The use of velocity spectrum for stacking receiver functions and imaging upper mantle discontinuities’ by H. Gurrola, J. B. Minster and T. Owens (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 124 (1996), S. 0

    Topics: Geosciences
    Notes: In a recent paper, Gurrola, Minster & Owens (1994; hereafter referred to as GMO) introduced a technique for the analysis of seismic data and applied it to the records of station OBN in Russia. GMO claimed that this was a new technique in earthquake seismology, and that their results for OBN provided a new insight into the deep structure of the Russian platform. We have some comments on their techniques and results.

    Notes: Abstract Excitation to the 1s 2 2s 2 2p 5 3p configuration in Mg III has been studied with optical spectrometry in the Mg+-He collision from 15 to 75 keV. The results are discussed and compared with the theory of Barat and Lichten, which predicts no such excitation. A possible explanation by Coulomb excitation is given.

    Release of microbial contamination from fractured solids (1969)

    Notes: Abstract Estimation of the probability of release of microbial contamination from the interior of solids upon fracture due to impact is essential to the formulation of planetary quarantine and spacecraft sterilization requirements. A model system was designed in which known concentrations of bacterial spores were incorporated in methyl methacrylate plastic. Pieces of plastic were fractured in a uniform manner exposing interior surface areas of consistent and measurable size. Known surface areas were incubated in sets of 20 culture tubes containing liquid growth medium. The subsequent occurrence of visible growth expressed as percent of tubes positive was interpreted as an estimate of the probability of release of at least one viable micro-organism. From these experiments probability of release as a function of microbial concentration in plastic was estimated for exposed interior surface areas of 30.6, 61.2, 91.8 or 122.4 mm2. Good agreement of the empirical results with a theoretical mathematical model of the probability of release of contamination from solids was demonstrated. Analysis of the data using the maximum likelihood procedure provided a means of calculating a proportionality constant representing the effective thickness of the exposed area and the characteristics of the recovery procedure.

    A sensitive method for determining nitrogen-15 isotope in urea (1997)

    Topics: Biology
    Notes: Abstract A method is presented in which the 15N at.% of urea is determined with high precision on liquid samples containing as little as 10 nmol of urea. The method involves removal of interference from NH4 + initially present in the sample by cation exchange. Urea in the sample is subsequently hydrolyzed to NH4 + by the enzyme urease. Liberated NH4 + is separated from the alkaline sample by diffusion as NH3 through a helium gas phase where it is finally oxidized to N2 by reaction with hypobromite iodine. The isotopically labeled N2 thus formed is mixed with the N2 initially present in the sample, and the 15N at.% of urea is calculated from the relative amounts of 14N15N and 15N15N by means of the isotope pairing principle. The presented method for 15N-urea analysis proved to be precise (SE 〈 0.4 at.%, n = 5), when applied on both marine and freshwater samples with an 15N enrichment 〉1 at.%, and interference was found only from volatile methyl amines.
