Let G be a finite group of Lie type of characteristic p, and k a sufficiently large field of the same characteristic. The permutation module Y=ind,.(k) on the right cosets of a Sylow p-subgroup tJ has been studied by several authors; the fundamental results are due to Curtis and Richen (see [S], whose used the module Y to describe the irreducible kG-modules. Later their results were reinterpret...

BACKGROUND Paraquat is a herbicide with a good occupational safety record, but a high mortality after intentional ingestion that has proved refractory to treatment. For nearly three decades paraquat concentration-time data have been used to predict the outcome following ingestion. However, none of the published methods has been independently or prospectively validated. We aimed to use prospecti...
