This study examined the importance of students' academic performance level and extracurricular activities as predictors of drug involvement relative to peer influence. Social development theory provided the theoretical rational for the study. Data we

Cardiac hypertrophy and function were evaluated in rats fed diets containing deficient, marginal or adequate levels of copper. The fat concentration of the diets was either 10 g/100 g corn oil, 10 g/100 g coconut oil or 10 g/100 g coconut oil + 1 g/1

The motion of vacuum arc cathode spots under the influence of the self-generated magnetic field has been investigated for copper electrodes at currents up to 6.9 kA. The spots were photographed with a high-speed framing camera. The magnetic flux dens

Measurements of the anode-cathode voltage of a high-current (>2 kA) vacuum arc are presented, attention being restricted to conditions which result in a smoothly varying voltage. It is found that under these conditions the voltage/current characteris

Reports on the preliminary results obtained with a new method of microparticle detection using forward scattering from a focused 4 W argon ion laser beam. For the first time microparticles are shown to be present in the interelectrode gap in the few

The decay of neutral copper vapour density which follows the extinction of a high current (2-11 kA) vacuum arc between copper electrodes has been measured. The results show that during the period 1-8 ms from current zero the vapour density decays at
