We report theoretical derivations and experimental results on the volume averaging effect of nonlinear processes in focused laser fields. This effect is considered detrimental in revealing the intensity dependence of a nonlinear process, caused by th

We present experimental results of electron diffraction of superfluid helium droplets and droplets doped with phthalocyanine gallium chloride and discuss the possibility of performing the same experiment with a laser aligned sample. The diffraction p

We present two facile time-of-flight (TOF) methods of detecting superfluid helium droplets and droplets with neutral dopants. Without an electron gun and with only a heated filament and pulsed electrodes, the electron impact ionization TOF mass spect

We report a facile method of doping cations from an electrospray ionization (ESI) source into superfluid helium droplets. By decelerating and stopping the ion pulse of reserpine and substance P from an ESI source in the path of the droplet beam, abou

The study of migrant labour in Africa has tended to emphasize social form rather than historical context. This study of the immense migrant labour force that worked the Northern Nigerian tin mines is placed in the context of the ongoing subsumption o

At the opening of the nineteenth century, the colonial order in South Africa was most seriously challenged on the eastern frontier, dramatized in white rebellions and the successful Xhosa-Khoi war of 1799–1802. The colonial government of the Batavi
