Ein Wassermolekül besitzt keine Gesamtladung. Es besteht jedoch eine geringfügige negative Ladung im Bereich des Sauerstoffatoms und eine geringfügige positive Ladung in der Nähe der Wasserstoffatome. Dies
Because the mean value of the current is null, the mean value of the electric field is also null. The quantity that is then needed is the correlation function of the current density which is given by the fluctuation- dissipation theorem derived in 1948. The full treatment has been first ...

The thrust of the helicon thruster will be measured with a null-type inverted pendulum thrust stand. The ion exit velocity will be measured with a retarding potential analyzer. Moreover CISAS is also conducting experimental tests in its own facility. Test results will be compared with results ...
In practice with PyHole light rays are traced backwards in time, starting at the camera, along null geodesics of the black hole metric. Each pixel on the camera image corresponds to a light ray with a different initial momentum vector, which will, as a result, follow a different trajectory...
Aufgrund der sehr niedrigen Oberflächentemperaturen, die etwa 50 °C unter Null betragen, würde das Wasser gefrieren, noch bevor es an die Oberfläche gelangt. Weitere Untersuchungen werden notwendig sein, um den Zusammenhang zwischen dem Grundeisspiegel und dem Vorkommen bzw. der...
