    Notes: [Auszug] We have investigated hyaluronidase activity in urine, in serum, and in various kinds of tissue extracts by a somewhat modified viscometric method2. One essential feature of this method is that flow-time is read every 1 or 2 min. A plot of flow-time against reaction time gave, for most urine ...

    Notes: Abstract The computation of mean sea surface heights from a set of collinear Geosat ERM altimeter data tracks was carried out in a collinear adjustment, where 1 cy/rev cosine and sine coefficients for each track are estimated, so the differences between the collinear tracks are minimized. Then bias/tilt cross-over adjustments of stacked Geosat and Seasat altimetry were carried out. The problems with the free surface in the cross-over adjusted altimetric surface were treated using the absolute sea surface heights relative to the geoid model OSU89B. In a combined adjustment of the two altimeter data sets using cross-over and height informations simultaneously a RMS of the cross-overs of 0.080 m and a RMS of the sea surface heights relative to OSU89B of 0.611 m were obtained.
