We report here the complete amino acid sequence of a pathogen-induced putative peroxidase from wheat (Triticum aestivum L.) as deduced from cDNA clones representing mRNA from leaves infected with the powdery mildew fungus Erysiphe graminis. The protein consists of 312 amino acids, of which the first 22 form a putative signal sequence, and has a calculated(More)
We have used a cDNA clone encoding a pathogen-induced putative wheat peroxidase to screen a genomic libary of wheat (Triticum aestivum L. cv. Cheyenne) and isolated one positive clone, lambda POX1. Sequence analysis revealed that this clone contains a gene encoding a putative peroxidase with a calculated pI of 8.1 which exhibits 58% and 83% sequence(More)
This paper describes a generic neural flight control and autopilot system, which can be applied to a wide range of vehicle classes. A neural flight control system is used to provide adaptive flight control, without requiring extensive gain-scheduling or explicit system identification. The neural flight control system uses reference models to specify desired(More)
Normally, the damage that results in a total loss of the primary flight controls of a jet transport airplane, including all engines on one side, would be catastrophic. In response, NASA Dryden has conceived an emergency flight control system that uses only the thrust of a wing-mounted engine along with a lateral center-of-gravity (CGY) offset from fuel(More)
Knowledge of the sources and distribution of ammonia (NH3) emissions underpins our understanding of the nitrogen budget. Research has focused on quantifying NH3 emissions from anthropogenic sources, whilst those from natural sources have received little attention internationally. Seabirds excrete large quantities of nitrogen, making seabird colonies a major(More)
This paper describes an authentication protocol that is suited to modern, object-based, client-server systems. Each object in a chain, whether acting in a client or server role, handles authentication with its neighbours, without any need to be aware of the resultant global behaviour. Session keys are returned by an authentication server which services a(More)
