    Histopathology in winter flounder (Pleuronectes americanus) living adjacent to a pulp and paper mill (1994)

    Notizen: Abstract Winter flounder were captured by scuba divers from an area adjacent to a sulfite pulp and paper mill and from a reference site and the tissues examined for lesions. Severe hyperplasia of the gills, focal vacuolation in the liver, and multifocal hemosiderosis in the spleen and liver were most pronounced in large, adult fish collected near the mill. Lesions were less severe and prevalent in smaller fish. Vacuolation in the liver represents a preneoplastic lesion. The histopathological changes appear to be the result of chronic exposure. Few or no lesions were observed in the tissues of flounder taken from the reference site. Although the specific cause of these lesions is unknown, it is likely associated with cytotoxic compounds.

    Anomalies in sculpins (Myoxocephalus spp.) sampled near a pulp and paper mill (1994)

    Notizen: Abstract This study investigated anomalies in two species of benthic sculpins (Myoxocephalus octodecemspinosus and M. scorpius) inhabiting a marine inlet in Newfoundland, Canada, where effluent from a pulp and paper mill is discharged and from two reference sites. Condition factor of both species of sculpins from the polluted and a reference site was similar. Some differences in parasite fauna were observed. Tissues from reference fish, obtained from two uncontaminated sites for comparison, were normal. Impaired vision, fin and tail necrosis, hyperplasia of the gill epithelium, depletion of energy reserves in the liver, and multifocal hemosiderosis in the spleen were observed primarily in M. octodecemspinosus captured near the paper mill. These stress-associated lesions, probably caused by undetermined xenobiotics, appear to be associated with the sediment.

    Notizen: [Auszug] SIR - Although the authors of "Bayesian reasoning in science" (Nature 350, 371; 1991) mentioned Bayes's original work, entitled "An essay towards solving a prob-lem in the doctrine of chances", they did not reference it. His original work, although rather lengthy, is available quite easily in The ...

    Flash calcines of kaolinite: Effect of process variables on physical characteristics (1992)
    Springer
    Journal of materials science 27 (1992), S. 2490-2500 
    Details
    ISSN: 1573-4803
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau
    Notizen: Abstract The physical transformation of powdered kaolinite associated with rapid dehydroxylation during flash calcination has been followed using pycnometry, thermogravimetry, electron microscopy, X-ray powder diffraction and infrared spectroscopy. 116 partially dehydroxylated kinetically-frozen calcines were produced in a laboratory flash calciner covering the following ranges of process variables: calciner temperature 700–1000 °C, rate of heating to calciner temperature 4700–15000 Ks−1, residence time at the calciner temperature 0.1–1.5 s, He or N2 calciner atmosphere. From the analyses of these calcines a picture of the changes in physical characteristics caused by flash heating of kaolinite has emerged and is described.
