    Notes: Abstract The RT1.C region has recently been defined genetically as a third region of the rat major histocompatibility system, RT1, and has been shown to code for cell-surface antigens with restricted tissue distribution (present on lymphocytes and absent from red blood cells and liver) and for target antigens of unrestricted cytotoxic T lymphocytes. Immunoprecipitation with C-antigen-specific alioantisera and SDS-PAGE analysis, reveal that C-region products are glycoproteins composed of molecules of 40 500–43 000 and 12 500 molecular weight, respectively. Thus, the RT1.B region, which codes for class II molecules, is flanked by RT1 regions which determine class I molecules (as defined biochemically), which are either expressed ubiquitously (RT1.A antigens) or in a restricted manner (RT1.C products). The homology to H-2Qa antigens is discussed.

    A new method to measure particle turbulent dispersion using laser doppler anemometer (1984)
    Springer
    Experiments in fluids 2 (1984), S. 89-93

    ISSN: 1432-1114
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A laser doppler anemometer (LDA) was used to measure local dispersion coefficients of particles in turbulent flow. The experimental set-up is described along with the data acquisition equipment and processing procedures. Results for 5 μ particles dispersing from a point source in pipe flow are shown. A second estimate for the diffusivity was obtained from mean square dispersion measurements.

    Chromosomal evolution in serpentes; a comparison of G and C chromosome banding patterns of some colubrid and boid genera (1980)
    Springer
    Chromosoma 79 (1980), S. 53-64 
    Details
    ISSN: 1432-0886

    Topics: Biology , Medicine
    Notes: Abstract G and C-chromosome banding techniques have been used to compare the structure of the karyotype in a variety of colubrid and boid snakes. The comparison of G-band patterns indicates that while some band sequences have been conserved, either as whole chromosomes or entire arms, there is also evidence of considerable rearrangement especially in the smaller chromosomes. In the colubrid Elaphe subocularis there is also evidence that there has been a relocation of the centromere on chromosome 2 without any accompanying inversion in the sequence of G-bands. Finally, G-banding has facilitated the demonstration of a simple pericentric inversion distinguishing the Z and W chromosomes in Acrantophis dumereli. This represents the first report of differentiated sex chromosomes in a boid snake. The combined banding data thus indicates that snake chromosomes are certainly not lacking in variability. The use of C-banding to detect constitutive heterochromatin has confirmed that in some boids and colubrids macrochromosomes have been derived from microchromosomes by the additions of heterochromatin.

    Copper accumulation in primary biliary cirrhosis (1982)
    Springer
    Histochemistry and cell biology 74 (1982), S. 85-93 
    Details
    ISSN: 1432-119X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Ultrastructural and X-Ray microanalytical aspects of primary biliary cirrhosis were analysed and compared to those of normal liver. Electron microscopic studies showed a significant increase of dense lipofuscin-like granules in PBC compared to the hepatocytes of normal liver (665%). These granules (0.3–2.7 μm in diameter) were formed by the association of primary lysosomes and lipid droplets. X-Ray microanalysis of these structures showed the presence of Calcium, Phosphorus, Potassium, Chlorine, Sulphur, Aluminium and Copper. The coexistence of Sulphur with other mineral elements suggests the occurence of metalloproteins binding these elements. These findings provide evidence that intralysosomal sequestration of mineral elements, especially copper protects the hepatocytes from cytotoxic effects.

    Photofission with linearly polarized photons (1982)
    Springer
    The European physical journal 308 (1982), S. 63-71

    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The formalism for fragment angular distributions in photofission with unpolarized and linearly polarized photons is summarized. First experiments on232Th using linearly polarized bremsstrahlung are described. The results for the analyzing power show for the first time in a model independent way that the low energy photofission can be explained byelectric dipole excitation. The possibilities of this new method are discussed, in particular when using monoenergetic tagged photons, which are available soon at new high duty cycle electron accelerators.

    Pore size and properties of spherical Ca-alginate biocatalysts (1983)
    Springer
    Applied microbiology and biotechnology 18 (1983), S. 86-91 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary A method for the production of spherical alginate gels from few μm up to several mm diameter is described. Alginate beads with diameters from 0.5 to 3 mm are used to immobilize microorganisms as biocatalysts. Micro size alginate gels are used as column packing material for inverse steric exclusion chromatography to determine their pore sizes from dextran standards of known molecular weight. The results indicate that alginate gels have pores which are large enough to release catalytic acting enzymes out of the matrix.

    Traditional healers in rural Hausaland (1981)
    Springer
    GeoJournal 5 (1981), S. 363-368 
    Details
    ISSN: 1572-9893
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geography
    Notes: Abstract Hausa communities in Nigeria are served by several distinct types of traditional healers. Practitioners who utilize various secular or technical approaches in healing may be distinguished from those who claim the ability to mobilize some spiritual or supernatural force for healing purposes. Hausa healers may be either sedentary or mobile, the latter following a regular circuit within a periodic market system, or moving randomly from village to village. The paper provides a description of the practice of medicine by the major categories of Hausa healers. Alternate sources of medicine, both traditional and Western, are listed. In conclusion, the future role of traditional healers in Hausland is briefly discussed.
