We derive a new set of equations to give successive positions of slowly moving and slowly turning curved shock front in a transonic flow. The equations are in conservation form two of these are kinematical conservation laws. keywords Curved shock propagation, shock dynamics, ray theory, transonic flow.

The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...

In recent months a bumper crop of genomes has been completed, including the fission yeast (Schizosaccharomyces pombe) and rice (Oryza sativa). Two large-scale studies of Saccharomyces cerevisiae protein complexes provided a picture of the eukaryotic proteome as a network of complexes. Amongst the other stories of interest was a demonstration that proteomic analysis of blood samples can be used ...

Since our last issue, several important genomes have been completely or 'almost completely' sequenced. The debate over the number of human genes has flared up once more, with one computational and one experimental study into the annotation of the human genome. The mouse genome project has a clone fingerprint map to aid their sequencing effort. The SAGE technique has been applied to Drosophila a...

This report on the literature spans from May to July, highlighting breakthroughs on several important genomes, including mouse, zebrafish, Fugu and Plasmodium. Recent papers have reported on a mechanism for genome size reduction in Arabidopsis, comparisons and verifications of large-scale protein-protein interaction datasets, developments in RNA interference approaches for mammalian systems and...

We examine multilateral bargaining in vertical supply relationships which involve an upstream manufacturer who sells through two competing retailers to end consumers. In these relationships the negotiations are inter-dependent and a bargaining externality may arise across the retailers. In addition, the timing by which the manufacturer negotiates with the retailers becomes important. The manufa...

The McGurk effect demonstrates the existence of a fusion process in audiovisual speech perception. We consider here the assumption that fusion is controlled by an upstream conditional binding process, which can block fusion in the case of strong audiovisual inconsistencies, as in the case of a dubbed film. To test this hypothesis, we designed two experiments in which a consistent or inconsisten...

This article considers the role of the four Ps marketing mix model in social marketing, arguing that given reconfiguration of the marketing mix in the mainstream marketing discipline, and the characteristics of social marketing, a re-thought and re-tooled social marketing mix is required. A brief review of the four Ps marketing mix model in the mainstreammarketing and social marketing fields is...
