    Superconducting thin films of Y-Ba-Cu-O prepared by metalorganic chemical vapor deposition (1990)

    Notizen: High throughput, low-temperature deposition, sharp interfaces, and selective deposition with direct ion-, electron-, and photon-beam-controlled techniques are some of the key driving forces for the development of superconducting thin films by metalorganic chemical vapor deposition (MOCVD) technique. In this paper we report on the electrical and structural properties of Y-Ba-Cu-O (YBCO) films deposited by MOCVD on yttrium-stabilized zirconia (YSZ) and BaF2/YSZ substrates using a single-step in situ processing method which requires no further annealing. YBCO films deposited on BaF2/YSZ substrates have zero resistance at 80 K. The films were characterized by energy dispersive x-ray analysis, x-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The films on BaF2/YSZ substrates exhibited textured growth having both the c and a axis perpendicular to the substrate. The use of BaF2 as a buffer layer suggests three-dimensional integration of high-temperature superconducting thin film for hybrid superconductor/semiconductor devices as well as superconductor switches and other related devices.

    Notizen: [Auszug] VLF observations at high latitudes are correlated with the influx of electrons1,2. VLF outbursts are also observed at low latitude stations3, and in trying to explain the origin of these VLF waves, Gurnett3 discarded the Čerenkov process because he was not able to find any correlation with ...

    Notizen: [Auszug] It is well known that the global thunderstrom activity is at a maximum at the temperate latitude and decreases with increasing latitudes7. The parameters or mechanisms controlling the guidance of thunderstorm-generated low-frequency waves are less effective at low latitude, however, which seems to ...

    Isolation and characterization of a virus (RL 1) infective on Rhizobium leguminosarum (1978)
    Springer
    Archives of microbiology 119 (1978), S. 263-267

    ISSN: 1432-072X
    Schlagwort(e): Rhizobium ; Virus ; Morphology ; One step growth ; General characterization

    Thema: Biologie
    Notizen: Abstract A virus (RL 1) that infects Rhizobium leguminosarum was isolated and studied. The virus has phagelike morphology; it has a hexagonal head and a long, flexible, noncontractile tail with a baseplate. The edgeto-edge diameter of head is 760 Å. The tail is 1515 Å long and 115 Å wide. RL 1 is stable at 4° C in distilled water, with only 20% loss in the titer after one month storage. It does not require any ion for stability, and is stable between pH 6.0 and 8.0. The virus is composed of two components; one is thermal sensitive and the other is relatively thermal resistant. Adsorption and ‘one step growth’ experiments under normal growth conditions showed a slow adsorption rate (0.82×10-9 cm3 min-1) followed by a 90 min latent period. The burst size was approximately 100 virus particles per cell.

    Tertiary trisomics of pearl millet (Pennisetum americanum (L.) K. Schum): its cytomorphology, fertility and transmission (1982)
    Springer
    Theoretical and applied genetics 63 (1982), S. 139-144

    ISSN: 1432-2242
    Schlagwort(e): Tertiary trisomic ; Pentavalents ; Pearl millet ; Transmission of trisomics

    Thema: Biologie
    Notizen: Summary Nineteen tertiary trisomics were isolated from some translocation heterozygotes and interchange trisomics of pearl millet. Cytological analysis of these trisomics indicates that chromosome association of trivalents, univalents and pentavalents were frequent in all the trisomics. But their ratio varied from one trisomic to the next. Other associations were relatively infrequent. The relative frequencies of 6 pentavalent configurations observed in different trisomics were studied and their probable association with mode of fertility and transmission rates have been discussed.

    Cosmic ray ionization of lower Venus atmosphere (1994)

    Notizen: Abstract Cosmic ray particles passing through dense lower atmosphere of Venus decay giving rise to various charged and neutral particles. The flux and degradation of dominant cascade particles namely neutrinos and pions are computed and ionization contributions at lower altitudes are estimated. Using the height profile of pion flux, the muon flux is computed and used to estimate ionization at lower altitudes. It is shown that cosmic ray produced ionization descends to much lower altitudes intercepting the thickness of Venus cloud deck. The dynamical features of Venus cloud deck are used to allow the likely charging and charge separation processes resulting into cloud-to-cloud lightning discharges.
