    • With an effective telescope area of order 104 m2 for TeV neutrinos, a threshold near ∼50 GeV and a pointing accuracy of 2.5 degrees per muon track, the AMANDA detector represents the first of a new generation of high energy neutrino telescopes, reaching a scale envisaged over 25 years ago. We describe early results on the calibration of natural deep ice as a particle detector as well as on AMANDA's performance as a neutrino telescope.

    • We review the status of the AMANDA neutrino telescope. We present resultsobtained from the four-string prototype array AMANDA-B4 and describe themethods of track reconstruction and neutrino event separation. We give also firstresults of the analysis of the 10-string detector AMANDA-B10, in particular onatmospheric neutrinos and the search for magnetic monopoles. We sketch thefuture schedule on the way to a cube kilometer telescope at the South Pole,ICECUBE.

    • The first stage of the AMANDA High Energy Neutrino Detector at the South Pole, the 302 PMT array AMANDA-B with an expected effective area for TeV neutrinos of ∼ 104 m2, has been taking data since 1997. Progress with calibration, investigation of ice properties, as well as muon and neutrino data analysis are described. The next stage 20-string detector AMANDA-II with ∼800 PMTs will be completed in spring 2000.

  • Interactions of intercalative and minor groove binding ligands with triplex poly(dA)•[poly(dT)]2and with duplex poly(dA)•poly(dT) and poly[d(A-T)]2studied by CD, LD, and normal absorption
  • 1996
  • Ingår i: Biochemistry. - : American Chemical Society (ACS). - 1520-4995 .- 0006-2960. ; 35:4, s. 1187-1194
  • Tidskriftsartikel (refereegranskat)abstract
    • The binding of 9-aminoacridine and one bis-acridine compound to double helical poly(dA). poly(dT) and poly[d(A-T)](2) and triple helical poly(dA).[poly(dT)](2) has been investigated using linear dichroism (LD) and circular dichroism (CD). A close examination of the negative reduced LD and the induced CD for the first pi --> pi* transition absorption region leads us to conclude that the acridine moiety of the 9-aminoacridine and bis-acridine molecule intercalates with both duplex and tripler DNA. Binding geometries of the acridine moieties in the examined polynucleotides are similar to those found for the ligands with DNA (Hansen et al. (1984) J. Chem. Sec., Chern. Commun., 509-511). It is also found that both 9-aminoacridine and bis-acridine effectively enhance the thermal stability of the tripler DNA. The corresponding spectra for the complexes of the minor groove binders DAPI and Hoechst with poly(dA).[poly(dT)](2) were studied for comparison. They both show a positive LD and a mixing ratio dependent positive CD in the ligand absorption region, similar to those of their duplex complexes. This indicates that these ligands bind in the grooves of the tripler, probably to the one corresponding to the minor groove of the template duplex.

  • Atomic force microscopy of rubbed polyimide aligning films for liquid crystal displays
  • 1995
  • Ingår i: 15th International Liquid Crystal ConferenceBUDAPEST, HUNGARY, JUL 03-08, 1994. ; , s. 89-98
  • Konferensbidrag (refereegranskat)abstract
    • The surface of polyimide (PI) films for aligning liquid crystals were studied by means of atomic force microscopy (AFM). The surface of the unrubbed PI films consisted of polymer clusters of different sizes which are randomly distributed over the film area. After rubbing, however, these polymer clusters formed long chains along the rubbing direction. The cluster chains were separated with periodicity about 100 nm for weak rubbing strength. Deeper grooves are also present, separated with periodicity about 2 mu m that could be related to the microstructure of the fibres from the rubbing cloth. On increasing the rubbing strength further on, the cluster chains coalesce into wider ones. The rubbed PI films show optical retardation, which was increased rapidly with increased the rubbing strength and reached a constant value of about 1.4nm.
