    Description / Table of Contents: Summary Question concerning the bifilar gravimeter: How have we to choose the constants of the apparatus and the dimensions of the instrument in order to promote the function of sensibility (that is to say sensibility depending upon deflection) as far as possible. The function of sensibility should have the most even flowing possible, as high as possible above the abcissa. The theoretical conditions for the best dimesions are derived and the possibility of a practical realisation is demonstrated.
    Notes: Zusammenfassung Es wird die Frage behandelt: Wie sind beim Bifilargravimeter die Apparatkonstanten und die Abmessungen des Instruments zu wählen, damit die Empfindlichkeitsfunktion (Abhängigkeit der Empfindlichkeit vom Ausschlag) besonders günstig wird? Die Empfindlichkeitsfunktion soll möglichst hoch über der Abszisse möglichst flach verlaufen. Die theoretischen Bedingungen für die beste Dimensionierung werden abgeleitet und die Möglichkeiten für eine praktische Verwirklichung aufgewiesen.

    Über Unterschiede in der Phase bei berechneten und beobachteten Tiden (1950)

    Description / Table of Contents: Summary An influence of the velocity of gravitation on the tides could not be detected. Phase differences between observed and theoretical tides (κ) may only be related to the local elastic behavior of the earth crust and the tidal friction. Peculiarly big values of κ are often observed, but greater accuracy of measurement and a more thorough elimination of disturbing influences will be required to account for them. Under certain circumstances it would seem possible to reduce the average phase deviations to ±0.7 minutes with regard to the half-day termsM 2 andS 2.
    Notes: Zusammenfassung Die Fortpflanzungsgeschwindigkeit der Gravitation macht sich auf die Erscheinung der Gezeiten nicht bemerkbar. Unterschiede in der Phase zwischen beobachteten und theoretischen Tiden lassen nur Schlüsse auf das örtliche elastische Verhalten der Erdrinde und auf die Gezeitenreibung zu. Zur Klärung von vielfach beobachteten ungewöhnlich grossen κ-Werten (Differenzen von theoretischen und gemessenen Tidenphasen) ist eine höhere Genauigkeit und eine gründlichere Elimination störender Einflüsse als bisher bei der Ermittlung der Tidenphasen anzustreben. Unter entsprechenden Voraussetzungen erscheint eine Reduktion der mittleren Streuung bei der Phase auf ± 0.7 Zeitminuten hinsichtlich der halbtägigen GliederM 2 undS 2 durchaus möglich.

    Deduktion einer allgemein gültigen erkenntnis (1950)

    Description / Table of Contents: Summary Starting from the general comprehensive conception that exists for us human beings, a deduction of fundamental intuition is produced. The knowledge resulting from it may be designated as short of any hypothesis, as absolute. A continuation of the specialisation is supposed to lead to branches of knowledge existing already, e. g. mathematics or physics.
    Notes: Zusammenfassung Ausgehend von dem allgemeinsten, umfassendsten Begriff, den es für uns Menschen geben kann, wird eine Deduktion fundamentaler Erkenntnisse erbracht. Das sich dabei ergebende Wissen ist als Voraussetzungslos, als absolut zu bezeichnen. Eine Fortsetzung der Spezialisierung kann auf bestehende Disziplinen wie z. B. Mathematik oder Physik hinauslaufen.

    Production of a microbial lipase by Staphylococcus carnosus (pLipMut2) in a bubble column reactor and a centrifugal field bioreactor (1991)

    Notes: Abstract Extracellular lipase production by the recombinant strain Staphylococcus carnosus (pLipMut2) has been studied. First substrate optimization was carried out in shaken cultures. As a result, the best substrate yield of 20 units/g (peptone + yeast extract) and maximum lipase activity in the culture supernatant of 1.7 units/cm3 could be obtained by a nutrient rich complex medium consisting of 75 kg/m3 yeast extract, 15 kg/m3 tryptone, 5 kg/m3 glucose and 0.5 kg/m3 K2HPO4. Higher initial substrate concentration caused inhibition of growth. Antifoam agent at higher levels than 1 cm3/ dm3 resulted in a negative influence on lipase yield. Comparative fermentation studies have been carried out in a bubble column reactor and in a centrifugal field bioreactor. Direct proportionality between growth, lipase production and oxygen consumption was observed. In the bubble column reactor usual superficial air velocities (4 cm/s) caused intensive foam generation, thus fermentation was only possible after installation of a broader column head to allow coalescence. In the centrifugal field bioreactor higher productivities were obtained without foam problems at superficial gas velocities which were one order of magnitude lower than in the bubble column. Fermentations have been performed batchwise and without holding pH constant. Neither pH control nor glucose feeding could improve the substrate yield further. Compared to former fermentation studies with the strain S. carnosus (pLipPS1) lipase yield (lipase activity/cell density) could be improved by 300% and substrate yield (lipase activity/substrate concentration) by 600%.

    Preparation of ultrathin metal-oxide layers by means of Langmuir-Blodgett films (1994)

    Notes: Abstract Langmuir-Blodgett (LB) films of fatty acid salts (Y-stearate, Y-arachidate, Cu-arachidate, Ba-stearate) were thermally oxidized. As a result one obtains ultrathin (a few Å thick) metal-oxide films at the substrate. The surface of the metal-oxide films was found to be rather inhomogeneous. Y and Cu ions remain quantitatively at the substrate despite the heating procedure. A linear dependence between area density of the metal ions in the oxidized films and the number of monolayers of the LB films was observed. The preparation of a mixed metal-oxide film containing Y, Ba, Cu with a given stoichiometry was found to be difficult due to the effect of counter ion exchange. The samples were investigated by means of plasma-desorption and spontaneous-desorption mass spectrometry, by Rutherford back-scattering and electron microscopy.

    Notes: Summary The composition of differently prepared Langmuir-Blodgett multilayers of ferric arachidate has been investigated by means of absorption Mössbauer spectroscopy and heavy-ion-induced mass spectrometry. We found that the iron concentration in qualitatively good films is 3.5 times higher than the stoichiometric value. Antiferromagnetic ordering in this two-dimensional model substance can be observed when the Fe−Fe distance in the layers is about 0.3 nm or below. The area density of the iron atoms in the planes decreases with decreasingpH values of the subphase which also leads to a disappearance of the long-range magnetic ordering and to a decrease of the Debye temperature of the films which is linearly dependent on the iron concentration in the films.
