The prevailing Western model of near-death experiences was defined by Moody's description of the phenomenon in 1975. To explore the influence of this cultural model, we compared near-death experience accounts collected before(More)
1. Control of enzyme formation has been examined in the pathways degrading mandelate and p-hydroxymandelate in Pseudomonas fluorescens. 2. The first three enzymes form a group which is common to both pathways and which is co-ordinately induced or repressed. The genes controlling these enzymes are assumed to form a ;regulon'. This group of enzymes is induced(More)
Preface Ian Stevenson is a man extraordinary in his intellectual and scientific accomplishments and even more extraordinary in his possession of a quality of mind which resists and never allows itself to be dominated by assumption. And so, against a powerful scientific ethos, which generally looks askance upon matters such as religions and more specifically(More)
This chapter focuses on digital technologies and geometry education, a combination of topics that provides a suitable avenue for analysing closely the issues and challenges involved in designing and utilizing digital technologies for learning mathematics. In revealing these issues and challenges, the chapter examines the design of digital technologies and(More)
Transmission of mitogenic and developmental signals to intracellular targets is often mediated by inositol derivatives. Here we present the cloning and characterization of a gene from Saccharomyces cerevisiae, PIK1, encoding the enzyme that catalyses the first committed step in the production of the second messenger inositol-1,4,5-trisphosphate. PIK1(More)
