Using the Hartree-Fock-Roothaan procedure the nuclear quadrupole interactions of the19F (spin 5/2) nucleus in CF4, SiF4 and GeF4 are studied. The theoretical results explain within 10% the observed experimental measurements by the time-differential p

The electric field gradient at the fluorine site of several crystalline trifluorides was measured by means of the time differential perturbed angular distribution method. The hyperfine data (vQ and η) are systematically analyzed by taking into accou

Magnetoencephalograms (MEG) from human brain were measured by means of a 37 channel SQUID magnetometer (KRENIKON). Correlation integrals were calculated from time series exhibiting strong α-rhythm in order to give estimates of correlation dimension

The K2-entropy is evaluated for experimental time series as well as for numerically simulated ones. The conventional calculation procedure leads to results that can be extrapolated to obtain a K2-value for the time series, but in the case of experime

Since many years the 19F-TDPAD method (TDPAD = time differential perturbed angular distribution) has been used to investigate electric field gradients in fluorine compounds. In these experiments always a strong reduction of the observed interaction a

The dynamical alteration between liquid phase and vapor phase was studied in a boiler system shown schematically in figure 1. The setup consists of a transport system for a liquid, which is heated up electrically at one end and cooled down by a heat
