    Notes: An error controlled finite element method (FEM) for solving stationary Schrödinger equations in three space dimensions is proposed. The method is based on an adaptive space discretization into tetrahedra and local polynomial basis functions of order p=1–5 defined on these tetrahedra. According to a local error estimator, the triangulation is automatically adapted to the solution. Numerical results for standard problems appearing in vibrational motion and molecular structure calculations are presented and discussed. Relative precisions better than 1e-8 are obtained. For equilateral H++3, the adaptive FEM turns out to be superior to global basis set expansions in the literature. Our precise FEM results exclude in a definite manner the stability or metastability of equilateral H++3 in its ground state.

    Notes: Zusammenfassung Es wird der Verlauf einer Tularämie-Epidemie im Spätsommer 1942 mit rund 100 Erkrankungen in der Dnjepr-Tjasmin-Niederung beschrieben. Die Tularämie trat hauptsächlich in der ulcero-glandulären Form in Erscheinung. Nach kurzer Wiedergabe mehrerer Krankengeschichten werden die klinischen, serologischen und mikroskopischen Untersuchungsergebnisse aufgeführt, sowie die geomedizinischen Verhältnisse dargestellt. Überträger waren hauptsächlich Mäuse — Hausmaus (Mus musculus), Brandmaus (Apodemus agrarius), Feldwühlmaus (Microtus arvalis) —und Wasserratten (Arvicula terrestris), daneben auch Hamster (Cricetus cricetus). Die Übertragung geschah vorwiegend durch mit Bact. tularensehaltigen Exkreten der erkrankten Nager infiziertes Wasser (Tjasminfluß) und Lebensmittel.

    Notes: Abstract The transient heating in an unsymmetrical, coated, hot-strip sensor was simulated with a self-adaptive finite-element method (SAFEM). The first tests of this model show that it can be used to determine, with a small error, the thermal conductivity of liquids, from the transient temperature rise in the hot strip, which is deposited in a substrate and coated by an alumina spray.

    Notes: Abstract Localization of a mammary-derived growth inhibitor (MDGI) in the bovine mammary gland was verified by light-and electron-microscopic methods. Expression of MDGI, which is known to inhibit the growth of mammary epithelial cell lines in vitro, was found to be highest in the late pregnant and in the lactating state. A combination of immunohistochemical and immunocytochemical methods with semi- and ultrathin resin sections revealed marked variations in MDGI staining. High MDGI levels were predominantly detectable in epithelial cells with large milk fat droplets. Distinct cell types that were almost free of label could be identified among bovine mammary epithelial cells that always exhibited high MDGI levels. Similar results were obtained when using a serum-free organ culture system in which MDGI was hormonally induced in cell types of comparable differentiation state. The specific occurrence of the growth inhibitor in developing alveoli and certain cell types points to the association between MDGI expression and functional differentiation in the normal mammary gland.

    Notes: Abstract. Mammary-derived growth inhibitor (MDGI) has previously been localized in the mammary parenchyma, dependent on the stage of differentiation of the mammary gland. Here, we have elucidated the distribution of MDGI in the mammary stroma by a combined immunohisto- and cytochemical analysis with antibodies raised against MDGI. Distinct staining of capillary endothelial cells has been revealed. Although its subcellular distribution resembles former observations in secretory epithelial cells, the expression of MDGI in capillary endothelial cells clearly precedes that in secretory epithelial cells. On the other hand, no endothelial MDGI staining has been detected in bovine heart, which contains a fatty acid-binding protein almost identical to MDGI. The localization of MDGI in the mammary capillary endothelium is discussed in terms of its possible involvement in the intracellular transport of hydrophobic ligands or in the regulation of endothelial cell proliferation.
