We report a diphtheria outbreak which occurred in the 1st 6 months of 1989 in the Quthing district of Lesotho in Southern Africa. Sixty-eight clinical cases were identified in patients with ages ranging from 14 months to 51 years. The 10-15-year age

The enhanced Raman effect is undetectable for pyridine adsorbed on smooth silver electrodes. It does appear, however, in a narrow range of the angle of incidence (5*), when less than a monolayer of Ag has been dissolved and redeposited electrochemica

Surface-enhanced Raman scattering (SERS) from ethylenediaminetetraacetic-disodium salt adsorbed on silver electrodes has been obtained for the 913, 935 and 1408 cm −1 modes. Addition of this salt to NaNO 3 solutions leads to an enhancement of the N

Solar selective absorbing Cr/SiO cermets were produced by rf-sputtering onto Cu substrates. The optical properties of the cermets depend on the volume fraction of Cr in SiO and on the layer's thickness. The influence of these parameters on the sputte

The temperature dependence of the energy and the linewidth of thek=0 optical phonons in Bi and Sb has been measured by Raman Scattering. The decrease in energy with increasing temperature is determined by the thermal expansion of the crystal whereas

The surface enhanced Raman scattering from pyridine molecules adsorbed on smooth copper or gold electrodes exhibits a similar strong enhancement as for pyridine on Ag. The intensity is very sensitive to the angle of incidence, and the signal is detec

Extremely intense Raman signals from pyridine adsorbed on single crystals with (111) and (100) orientation and polycrystalline silver electrodes are reported. To obtain these intense Raman signals with an enhancement factor of 10 5 only one carefully

Molecules in certain excited states can be forced to predissociate in an external electric field. This effect will be shown to occur with H2 and D2. The molecular dissociation is made possible by an altered coupling mechanism as compared to the mecha

Molecular hydrogen was excited by selective absorption of ultraviolet radiation of appropriate wavelength into the vibrational levels ν′ 3, 4, and 5 of the electronic D (1IIu)-state. For the radiation bandwidth chosen the molecule was only formed
