Hodson, M E, Brailey-Jones, P, Burn, W L, Harper, A L, Hartley, S E, Helgason, T & Walker, H F 2023, ' Enhanced plant growth in the presence of earthworms correlates with changes in soil microbiota but not nutrient availability ', Geoderma, vol. 433, 116426 . https://doi.org/10.1016/j.geoderma.2023.116426
Earthworms enhance plant growth but the precise mechanism by which this occurs is not known. An understanding of the mechanism could potentially support changes in agricultural management reducing fertiliser usage and therefore costs and the carbon f

The major goal of this research has been to develop improved numerical methods for the solution of large-scale systems of linear and nonlinear equations, such as occur almost ubiquitously in the computational modeling of physical phenomena. The numer

Newton iterative methods, also known as truncated Newton methods, are implementations of Newton`s method in which an iterative linear solver is used to solve approximately the linear systems that characterize Newton steps. These methods are particula

Objective is to develop robust, efficient Newton iterative methods for general large scale problems well suited for discretizations of partial differential equations, integral equations, and other continuous problems. A concomitant objective is to de

During the 1986--1989 project period, two major areas of research developed into which most of the work fell: ``matrix-free`` methods for solving linear systems, by which we mean iterative methods that require only the action of the coefficient matri

The relative efficacy of thiamine supplementation to sheep by injection, subcutaneous implant and orally administered protected thiamine bolus was compared in two experiments using a grass and hay ration and a ration containing bracken rhizomes to in
