We wish to discuss some aspects of repetends, the repeating sequence of digits in the expansion of a fraction (for illuminating introductions to the subject see [1, 2]). For the most part we restrict consideration here to fractions with a prime denom

High-frequency electrostatic waves have been observed in a two-electron-temperature plasma. Both bi-Maxwellian and Maxwellian-waterbag models were found to be inadequate in explaining the observed dispersion and damping rates. However, modelling of t

Electron energy distributions (EED) in strongly magnetized (∼0.3 T), low-pressure (∼0.2 Pa) helium plasmas of the toroidal device “Blaamann” [K. Rypdal et al., Plasma Phys. Controlled Fusion 36, 1099 (1994)] have been measured. In the analysi

In field tests we have observed year-to-year differences in the severity of the effects of soil compaction on nodulation and growth of common bean; these differences appeared to be related to the amount of rainfall during the growing season. We decid

A kinetic theory has been developed to enable electron energy distributions to be derived when a strong magnetic field is present. The computational techniques involved are emphasised and illustrated by examples taken from probes on the toroidal mach

This article is based on wave experiments performed in the toroidal plasma device Blaamann, and a comparison between experimental and theoretical values for the dispersion relation. A motorized probe, which could be moved in two axial directions, gav

In the BLAAMANN device a weakly ionized hydrogen plasma is produced by electrons accelerated from a hot, negatively biased tungsten filament and confined in a toroidal magnetic field of strength up to 0.4 T. The plasma is turbulent, with relative flu

The transplantation of human fetal ventral mesencephalic (VM) tissue for patients with advanced Parkinson's disease (PD) has now proved to be of benefit in early clinical trials (1-3). This has been clearly seen in terms of improved motor function, w

The response of a probe with varying applied potential is studied by numerical simulation. Each particle is followed in turn in its path through the test volume and leaves a space charge in its track for the next overall iteration. The space charge i
