Abstract

The “non-Darcian” behaviour of water in soils is discussed considering the coupling that can arise between the different transport phenomena. In general, it is shown that there is a reason to expect that a difference in osmotic pressure will arise when solutions flow through porous media, and that due to that difference the resulting flow be related in a non-linear fashion to the applied pressure difference. Several numerical examples are presented illustrating this behaviour.     

P. G.-Seismographen und ihre Eichung

Zusammenfassung Es wird die Theorie der Pendel-Galvanometer-Seismographen (P. G.-Seismographen) ergänzt, eine neue Eicheinrichtung beschrieben und als Beispiel einHiller-Askania-Seismograph geeicht.

Summary A contribution to the theory of the galvanometric seismographs is given. Two new shaking tables are described and as an example aHiller-Askaniaseismograph is calibrated.
