[en] Due to their outstanding properties, e.g., good contrast, wide viewing angle, low power consumption, and self-emission organic light-emitting (OLE) displays on the basis of conjugated polymers are on the verge of commercialization. Two major disadvantages of the current processing technique for the polymersemdashspin coatingemdashare the material waste and the difficulties involved in patterning multichrome or even full-color displays. Therefore, we investigated the screen-printing technique for the production of OLE displays. In this letter, we present performance data and images of screen-printed OLE diodes. They are already comparable to spin-coated ones. We observed luminance of 10000 cd/m2 at 8 V and peak efficiencies exceeding 10 cd/A for green diodes. These data indicate that printed organic displays have the potential to replace 'classical' spin-coated devices. [copyright] 2001 American Institute of Physics

[en] The paper summarizes the results of studies carried out on the occurrence and physical state of Pseudorabies virus (PRV; Suid herpes virus 1) DNA in latently infected swine. During latency (between 7 and 52 weeks post-infection) 0.05 to 0.3 genome copies per cell were detected in different neural areas and extraneural cells of swine. During the latent state the predominant form of the PRV genome was found to represent linear, unit-length DNA. In some cases, two types of viral DNA alteration were found in the latently infected organ cells: (a) deletion of about 750 base pairs had occurred in the unique short region of PRV DNA, and (b) the abundant presence of limited portions of the viral genome. Results are also presented on the influence of a PRV glycoprotein (gI) in possibly controlling viral virulence. Avirulent PRV vaccine strains were shown not to express gI or its precursor protein. Analysis of the gI expression was further extended to other virus isolates obtained in vitro and in vivo. These data show a highly variable expression of gI in PRV, both qualitatively and quantitatively, leading to a loss of in vitro neutralization, with anti-gI monoclonal antibodies in some cases.

[en] Complete text of publication follows. In 2005 (Taylor et al., 2005-Earth Observation with CHAMP Results from Three Years in Orbit) computed and interpreted a CHAMP satellite magnetic anomaly map, at 400 km altitude, over the Pannonian Basin and surrounding region using the method of Alsdorf et al. (1994). This area was chosen since it has one of the thinnest continental crusts in Europe and is the region of complex tectonic structures. The future SWARM satellite constellation of three spacecraft, with one at a high altitude and the other two lower, will initially be at the same altitude as CHAMP but eventually they will descent to a lower altitude. We recomputed our most recent satellite magnetic anomaly map, using the spherical-cap method of Haines (1985), the technique of Alsdorf et al. (1994) and from spherical harmonic coefficients of MF6 (Maus et al., 2008) employing the latest and lowest altitude CHAMP data, in order to evaluate and reinterpret these newer data to determine the advantage of lower altitude satellite data. The SWARM constellation will have the two lowest altitude satellites flying abreast, with a separation of between ca. 150 to 200 km. to record the horizontal magnetic gradient. Since the CHAMP satellite has been in orbit for eight years and has obtained an extensive range of data, both vertically and horizontally there is a large enough data base to compute the magnetic gradients over the Pannonian Basin region using the many orbits. We computed the magnetic anomaly gradients in order to determine how these component data will improve our interpretation and to preview what the SWARM mission will reveal with reference to the horizontal gradient anomalies.
