    Notes: We have used transmission electron microscopy to study magnetization processes in Co/Cu multilayers with the Cu spacer layer thickness close to 9 Å. The films show giant magnetoresistance (GMR) values (approximate)25%, saturation fields of 1–2 kOe, and very little magnetoresistive hysteresis; they are of interest as position sensors. While the Cu thickness was chosen to correspond to the first antiferromagnetic maximum, magnetic images taken throughout a magnetization cycle attest to the fact that the antiferromagnetic coupling is far from complete. Detailed analysis of image sequences and the corresponding low angle diffraction patterns suggests that the coupling is dominated by a biquadratic component. This is consistent with the relatively low value of GMR. Furthermore, the well-defined and relatively simple domain processes which are observed over the low field regime (±50 Oe) explain why little hysteresis is observed. © 1999 American Institute of Physics.

    Notes: Abstract: DNA flow cytometry has been extensively studied in female breast carcinoma. However, there is limited data evaluating DNA ploidy in male breast cancer. In order to further assess the prognostic significance of DNA ploidy in male breast carcinoma, we retrospectively reviewed 55 cases (52 patients) of histologically proven male breast carcinoma treated at our institution from January 1971 through January 1992. Of the 55 cases, 32 paraffin-embedded blocks were available for DNA flow cytometry analysis. As of June 1993, median follow-up is 7.0 years. In the overall population of 55 cases, univariate analysis identified TNM stage, tumor size, and nodal status as significant prognostic indicators of overall survival and disease-free survival. In the 32 cases available for DNA flow cytometry, both local recurrences and distant metastases were more frequent in the aneuploid population. Univariate analysis revealed DNA ploidy to be a significant prognostic factor for local recurrence-free survival and distant metastasis-free survival. DNA ploidy correlated significantly with stage at diagnosis (p =.04), tumor size (p =.04) and nodal status (p =.02). In a multivariate analysis of 26 patients on whom all data were available (DNA ploidy, tumor size, clinical stage and nodal status), DNA ploidy was an independent predictor of disease-free survival (p =.05). In this retrospective analysis, we conclude that DNA ploidy has prognostic significance in male breast carcinoma.

    Continuous fabrication of high-temperature superconductor coated metal fiber and multifilamentary wire (1991)

    Notes: Long superconductor fibers have been continuously produced by electrophoretically depositing REBa2Cu3O7−x (where RE=Y or a selected rare-earth element) powder onto a metal substrate fiber and sintering, then electrophoretically depositing silver and sintering. After collecting the coated fiber on a take-up spool, the entire spool is batch-oxygenated to form the 90 K superconducting phase. Multiple fibers are then continuously unspooled and soldered into a copper channel to form the final multifilamentary high-temperature superconductor wire. Superconducting fibers over 1000 m long and multifilamentary wire 70 m long have been produced.

    Notes: The shape and crystallography of fatal electromigration voids in near-bamboo Al-2 wt % Cu thin-film conductors were studied with transmission electron microscopy. Fatal voids were typically slit shaped and intragranular. Voids formed with {111} faces and with the slit length parallel to a 〈022〉 direction. The void faces were inclined and resided in grains of varying surface crystallographic orientation. Void morphology was independent of initial precipitate condition.

    Resistance of new Belgian poplar clones to British isolates of the bacterial canker pathogen, Xanthomonas populi (1998)

    Notes: Forty-nine new poplar clones, bred in Belgium and screened there for resistance to bacterial canker caused by Xanthomonas populi, were additionally screened in southern England, using British isolates of the bacterium. Thirty-five of the test clones ranked better than the clone ‘Boelare’, which is already registered in the UK as an approved clone, and is regarded as having acceptable resistance. The registered clone ‘Ghoy’ was more susceptible, and outranked only four test clones. Preliminary measurements of canker length and stem girdling index showed differences between five bacterial isolates.

    An unusual Phytophthora associated with widespread alder mortality in Britain (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 44 (1995), S. 0 
    Details

    Notes: During 1993 and 1994 an unusual Phytophthora was consistently isolated from bark lesions at the stem bases of dying alder in Southern Britain. The Phytophthora resembles P. cambivora in both its gametangial and sporangial morphology. However, it is distinct from this species in being homothallic rather than outcrossing; in producing a significant proportion of small and sometimes partially developed oogonia; in having a high frequency of oosphere abortion; in having an appressed felty colony type with little or no aerial mycelium; and in exhibiting a lower optimum temperature for growth (c.22-5°C) and lower growth temperature maximum (c.29°C) on carrot agar than P. cambivora (c.27-5° and 33-5°C respectively). An inoculation test confirmed its pathogenicity to Alnus. The status of the alder Phytophthora is discussed. On the basis of its unusual characteristics and unusual host it is suggested that it might be a new or recently introduced organism rather than a previously unrecorded indigenous variant of P. cambivora.

    Major river systems of central and southern Britain during the Early and Middle Pleistocene (1994)

    Notes: Central and southern Britain was drained by two main river systems during the larger part of the Early and Middle Pleistocene: the Thames and Bytham rivers. Evidence for these rivers and their Quaternary history is represented by their sediments (the Kesgrave and Bytham Sands and Gravels, respectively), the geomorphological position of the sediments, biostratigraphy and amino acid geochronology. Evidence from the earlier parts of the Early Pleistocene (Tiglian C4b and earlier) indicates low-energy river systems and marine conditions over much of East Anglia. For most of the Early Pleistocene (Tiglian C4c to the Cromerian Complex) the ancestral Thames was the main river with, at its maximal extent, a catchment that extended into Wales, and across East Anglia and what is now the North Sea, to join the ancestral Rhine. During this period, glaciers in the uplands of Wales and periglacial mass movement elsewhere supplied material to the catchment and it was at this time that the bulk of the sorted Quaternary ssediments of lowland Britain were deposited. The Bytham river system has no successor because the landscape now in existence has been fundamentally altered by glacial erosion. This catchment drained most of Midland England and joined the Thames in central East Anglia. Initially, the Bytham river was a tributary of the Thames, but over time it extended its catchment and at the beginning of the ‘Cromerian Complex’it became the main river of southern Britain. With the Anglian Glaciation (01 Stage 121, the Bytham river was destroyed and the Thames was diverted to its present route through London.
