Mexicans required the stimulus of the influenza epidemic of 1918 before they established a state board of health. He describes the efforts to eradicate malaria between 1923 and 1947, and the contemporaneous success in reducing high infant and maternal death rates. After analysing changes in physician supply and distribution since statehood, Spidle concludes with an analysis ofthe growth of boar...

Methods and results Child (aged <15 years) pedestrian death rates (ICD code E814-7) were calculated by using National Health Statistics Centre mortality data for 1967 to 1987. A traffic volume index, based on data from traffic counters on urban highways throughout New Zealand, and the number of registered vehicles were obtained from the Ministry of Transport. There was an annual average of 32 5...

Problem 198. Pi Mu Epsilon Journal 4(Fall 1967)296 A semi-regular solid is obtained by slicing off sections from the corners of a cube. It is a solid with 36 congruent edges, 24 vertices and 14 faces, 6 of which are regular octagons and 8 are equilateral triangles. If the length of an edge of this polytope is e, what is its volume?

One of the most fascinating features of the mechanism proposed by Phillips and co-workers (Blake et aI., 1967a, b; Phillips, 1966) for the cleavage of oligosaccharides by lysozyme is the distortion of the saccharide bound in subsite D into a half-chair conformation. This mechanism is based upon X-ray crystallographic studies of the non-productive complex of lysozyme with chitotriose, GlcNAc-,B(...
