We survey recent results on the use of trajectories as a tool for modelling language operations and other, related objects. Many applications of the concept of trajectories have been developed since their introduction by Mateescu, Rozenberg and Salomaa in 1996. Areas which have seen activity include the theory of codes, language equations, modelling noisy channels, grammar models and DNA code-w...

Major F. W. Cragg

It is with the deepest regret that we learn of the tragic death of Major F. W. Cragg, i.m.s., from typhus fever at Lahore on the 23rd of April, 1924. Major Cragg's death adds another name to the long but brilliant list of scientific investigators who have lost their lives in the prosecution of medical enquiries for the benefit of humanity. He died as truly on active service as did any officer k...

F/W e+e- INTERACTIONS*

INTRODUCTION The field of e+e-interactions has provided a great deal of excitement in the past few years. 1-9 Primarily, interest has centered around the reaction +-ee-hadrons. This reaction is particularly attractive because we believe in electromagnetic perturbation theory, which implies that the cross section for hadron production is dominated by one photon annihilation of the electron and p...

WIND-CHILL E F F E C T F O R C A T T L E AND SHEEP t D. R. Ames and L. W. lnsley

Effective temperature is a term used to rate the cooling or heating power of the physical environment in terms of dry bulb temperature. For livestock exposed to cold, windy environments, effective temperature must now be predicted by a wind-chill index prepared for humans and designed without regard to extemal insulation_ suck~hai r or wool. The human wind-chill relationship is quadratic in nat...
