    Notes: Abstract Purpose. This work was carried out to determine the surface tension of block copolymer micelles of 14C labelled ABA poly (oxyethylene-bi-isoprene-b-oxyethylene) which have a long circulating half life in animals. Methods. The method used was that of phagocytosis. The percentage of micelles phagocytosed by human mononuclear cells was determined in solutions of different surface tension. Results. The values obtained were 72 mN/m which may be predicted for a particle with a long circulating half life in animals. The method also gave an estimate of the surface tension for the mononuclear cells. Conclusions. This technique has the advantage of determining the surface tension of highly hydrated small particles including stable micelles in an environment similar to that in which they normally exist.

    Description: Nearly complete mosaics of winter ice surface velocities for the 1990's over the Eastern Arctic (Novaya Zemlya, Franz-Josef-Land, Severnaya Zemlya and Svalbard) were compiled based on historical SAR data. Offset-tracking to JERS-1 SAR data of the time period 1992-1998 was mainly applied. Data gaps were complemented using SAR interferometry and offset-tracking of ERS-1/2 SAR data of the time period 1991-1997. Knowledge on ice surface velocity of glaciers and ice caps contributes to a better understanding of a wide range of processes related to glacier dynamics, mass change and response to climate. In order to study long-term variability of winter ice surface velocity from the 1990's to present, velocity maps computed with offset-tracking from 2008-2011 ALOS-1 PALSAR-1 and 2020-2021 Sentinel-1 data are also provided.
