Social Learning in European River-Basin Management: Barriers and Fostering Mechanisms from 10 River Basins

We present and analyze 10 case studies of participatory river-basin management that were conducted as part of the European HarmoniCOP project. The main theme was social learning, which emphasizes the importance of collaboration, organization, and learning. The case studies show that social learning in river-basin management is not an unrealistic...

The decrease in upper-atmosphere density between 1957 and 1963, as revealed by satellite orbits

The density of the upper atmosphere at heights of 200-750 km is calculated from the rate of decrease of orbital period for 38 satellites at dates between October 1957 and January 1963. The air density at these heights is strongly linked with solar activity, and as solar activity declined between 1958 and 1962, the density decreased greatly, by a...

Table of the artificial earth satellites launched in 1957-62

A Table is given of all known artificial satellites launched before 1st January, 1963, with lifetimes, weights, dimensions and details of the orbits, whenever known, for all instrumented satellites and their rockets. Other fragments from the satellites are listed without these details. The methods used in compiling the Table and the difficulties...
