Finite difference methods for the volume conductor problem have used a single coordinate system for the mesh and made approximations of Laplace's equation. This method is simple but has two major problems. Firstly, to deal with boundary conditions pr

This paper presents a new vector interpolation method for Phong shading, referred to as binary interpolation. It can calculate the reflection model by a scalar method. A pre-defined table is used to convert scan lines into segments, each of which is

A description is given of a new microprocessor-based device for EEG analysis. The Cerebral Function Analysing Monitor (CFAM) analyses the EEG amplitude and frequency dittribution. It produces a detailed plot of amplitude trends and separate traces of

The continuous infusion of Althesin under electroencephalographic (e.e.g.) control provided a constant level of light anaesthesia for periods of 1--5.5 h during experimental brain hypoxia in spontaneously breathing baboons and Rhesus monkeys. Polygra

When cultured on a medium containing d -[ 14 C 6 ]glucose and dl -tartrate, Penicillium charlesii G. Smith synthesizes a polygalactofuranoside containing 14 C. Isotope from dl -[1, 4- 14 C 2 ]tartrate is also incorporated under identical growth condi

Nitric-perchloride acid, 0.5 M hydrochloric acid, 0.05 M EDTA and neutral ammonium acetate were investigated as extractants for copper in peat samples. Greatest contrast between anomalous and background samples was found with nitric-perchloric acid (

A novel method is described of recording EEG by means of electrodes in de-ionised water in which the scalp is immersed. It permits large numbers of closely packed electrodes to be connected quickly both in the plane of the scalp and three-dimensional

A device, the cerebral function monitor, provides a continuous record of the electrical activity of the brain occurring at frequencies from 2 to 15 Hz. It is relatively cheap, portable, and easy to use and interpret. The apparatus has proved of value

Cerebral function monitor (CFM) recordings were obtained from 107 neonates, considered by pediatricians to be neurologically normal on discharge from hospital. Maturational changes in sleep patterns for the tracings over the conceptional age range 30
