We 1 present a method for controlling autonomous agents in un-predictible environments. For this, the agent's architecture of Hayes-Roth et al. (1995) is extended regarding spontaneous goal generation and goal selection. This method seems psychologically plausible under the term motivation. In addition, its implementation exhibits attractive real-time characteristics, relating environment, agen...

Spontaneous histamine release from isolarted Mastcells was found to be independent of cal­cium in the concentration range up to 1 m. mole/lit. Phosphatidyl serine do not change the effect of calcium on spontaneous release. The activation of anaphyla.ctic histamine release by calcium is potentiated by phosphatidyl serine but the laitter can't do so w1th strontium.  Mastcells, pretreated with AT...
