To investigate the effect of discontinuity of 1-D pinning centers on the flux pinning in a wide range of magnetic field directions, discontinuous columnar defects (CDs) and continuous CDs were formed in GdBCO coated conductors using Xe-ion irradiations with 80 and 270 MeV, respectively. An overall shift upward in J<sub>c</sub>, for the 80-MeV-irradiated(More)
To investigate whether one-dimensional pinning centers can attain the isotropic critical current density <formula formulatype="inline"><tex Notation="TeX">$(J_{\rm c})$</tex></formula> properties, columnar defects (CDs) crossing at widespread angles were installed by heavy-ion irradiation into YBCO thin films. For the sample containing the CDs crossing at(More)
Kaolin induced a clear and reproducible writhing reaction when intraperitoneally injected into mice. A simultaneous injection (i.p.) of soybean trypsin inhibitor (SBTI) significantly suppressed the kaolininduced writhing reaction. This writhing reaction was markedly potentiated by a simultaneous injection (i.p.) of captopril. In anin vitro experiment kaolin(More)
We have surveyed a ∼0.9-square-degree area of the W3 giant molecular cloud and star-forming region in the 850-μm continuum, using the SCUBA bolometer array on the James Clerk Maxwell Telescope. A complete sample of 316 dense clumps was detected with a mass range from around 13 to 2500M⊙. Part of the W3 GMC is subject to an interaction with the Hii region(More)
The metal Al is lighter in weight than other substrate materials for MgB<sub>2</sub> filmssuch as Si and Ni. This property inspires MgB<sub>2</sub> fabrication on a large-scale Al substrate as a new route to MgB<sub>2</sub> tapes. Here we report microstructural factors influencing critical current density, <i>J</i><sub>c</sub>, in MgB<sub>2</sub>/Al films.(More)
We present the results of a series of observations of the near-and mid-infrared polarisa-tion properties of the Seyfert 2 galaxy NGC1068. Our data agree well with previously published results in showing the need for a separate polarisation mechanism in the near infrared apart from scattering. We find that the predictions of a simple model in which this(More)
