The peak current, peak voltage, charge transfer and energy dissipation necessary for equivalent stimulation were measured for several pulse durations in the range from 0.01 to 1.0 msec. The unidirectional, regulated current, rectangular waveform was studied for subcutaneous nerve and intramuscular stimulation in animals and for surface stimulation in(More)
2014 Experimental values are reported for the distortion viscoelastic and elastic ratios for a homologous series of nematic Schiff’s bases : APAPAm (m = 1-5, 9) and OHMBBA as a function of temperature. In the experiments the homodyne photoelectric self-beat technique was used to detect noise intensity spectra and to determine the angular distribution of(More)
Die direkte elektrische Reizung eines Masseter fiihrt zur I t emmung desselben und des kontralateralen Muskels, sowie des M. temporalis beidseits. Nach ])urchschneiden der portio major liil~ sich yon dieser Seite aus die t t emmung nich~ mehr auslSsen, wohl aber yon der Gegenseite. Eine antidrome I t emmung ist anatomisch ausgeschlossen, da die motorischen(More)
Durch afferente Tetanisierung der beiden durchschnittenen Gastrocnemiusnerven einer Hinterextremität wurden an decerebrierten und zugleich de-efferentierten Katzen tonische Entladungen in funktionell isolierten Motoneuronen des unteren Lumbalmarks ausgelöst. Die Inhibition dieser Entladungen durch antidrome Reizung der entsprechenden Ventralwurzel kann(More)
2014 We report a study of the viscoelastic and elastic properties of a nematic liquid crystal as measured by static and dynamic light scattering. Experimental values are reported for the splay/twist/bend elastic and viscoelastic ratio as well as for the Mi0119sowicz viscosity ratio ~1/~3 of APAPA in the nematic region as a function of temperature.

2014 Experimental values are reported for the splay/twist viscoelastic ratios of OHMBBA in the nematic region as a function of temperature. In the experiments the homodyne self-beat technique was used to detect noise intensity spectra of laser light scattered by the nematic liquid crystal. The measured rotational viscosity can be described as a function of(More)
