The Wave Experiment, F4, on the Swedish/German satellite Freja, is designed to measure the electric wave fields up to 4 MHz, the magnetic wave fields up to 16 kHz and the plasma density and its relative variations up to 2 kHz. Six wave signals and four density probe signals can be measured simultaneously. The wave forms of all signals are transmitted to ground without any analysis onboard. The limited TM allocation does not allow continuous sampling of the wave signals, so normally the measurements are made in snapshots of various lengths dependent on sampling frequency, etc. Continuous sampling can be made for shorter time periods by using a 6 Mbyte memory as a buffer.

Isolierte peritoneale Mastzellen der Ratte wurden in KRG-Puffer mit Reserpin und Guanethidin inkubiert. Beide Substanzen scheinen unabhangig voneinander aufgenommen zu werden, da die gleichzeitige Inkubation mit Reserpin und Guanethidin die Aufnahme im Vergleich mit den Kontrollen nicht herabsetzt.
