Conducting randomized trials in general practice : methodological and practical issues
Ward, E.; King, M.; Lloyd, M.; Bower, P.; Friedli, K. (1999-11)The evaluation of the outcome of health services technologies is a requirement for their efficient provision in clinical practice. The most reliable evidence for treatment efficacy comes from randomized trials. Randomized ... -
Development and Application of Molecular Methods for the Study of Polymyxa betae
Mutasa-Gottgens, Euphemia; Chwarszczynska, D. M.; Williams, G.; Ward, E.; Adams, M. J.; Asher, M. J. C. (American Society of Sugar Beet Technologists, 1996)A simple method for cloning Polymyxa betae DNA from infected sugar-beet roots has been developed and used to isolate a multi-copy genomic DNA fragment, pPbKES-1, located on at least four different P. betae chromosomes. ... -
Generation of a ribosomal DNA probe by PCR and its use in identification of fungi within the Gaeumannomyces-Phialophora complex
Ward, E.; Gray, R. M. (1992-12)The polymerase chain reaction (PCR) was used to amplify a ribosomal DNA fragment from Gaewnannomyces graminis. This fragment was labelled and tested for its usefulness as a probe in restriction fragment length polymorphism ... -
Identification of Gaeumannomyces-Graminis var. tritici and G-graminis var avenae using a DNA probe and nonmolecular methods
Bateman, Geoffrey L.; Ward, E.; Antoniw, J.F. (1992-09)Fungi in the Gaeumannomyces-Phialophora complex were compared using a DNA probe and by pathogenicity and other biological tests. Isolates from cereal and grass hosts which were pathogenic on cereals were differentiated as ... -
The role of seeds and airborne inoculum in the initiation of leaf blotch (Rhynchosporium secalis) epidemics in winter barley
Fountaine, J. M.; Shaw, M. W.; Ward, E.; Fraaije, B. A. (2010-04)Both airborne spores of Rhynchosporium secalis and seed infection have been implied as major sources of primary inoculum for barley leaf blotch (scald) epidemics in fields without previous history of barley cropping. ...
