The Antrim Coast Road – a civil engineering legacy
Autor: D. M. Orr
Publikováno v: Proceedings of the Institution of Civil Engineers - Engineering History and Heritage. 163:65-69
In the early 1800s, the Commissioners of Public Works in Ireland conceived the idea of building the Antrim Coast Road to open up the Glens of Antrim, to give better access for the military, and to give work to the unemployed. Their civil engineer, Wi

Condition-based capital valuation of a road network
Autor: M. S. Snaith, D. M. Orr
Publikováno v: Proceedings of the Institution of Civil Engineers - Municipal Engineer. 159:91-95
The introduction of resource accounting for public assets in the United Kingdom and elsewhere has brought with it the need to determine the capital value of road networks, including the loss of value due to deterioration in service. Various methods h

Corrigendum to: Impacts of level of utilisation by grazing on an Astrebla (Mitchell grass) grassland in north-western Queensland between 1984 and 2010. 1. Herbage mass and population dynamics of Astrebla spp
Autor: D. M. Orr, David Phelps
Publikováno v: The Rangeland Journal. 36:309
Managing large variations in herbage production, resulting from highly variable seasonal rainfall, provides a major challenge for the sustainable management of Astrebla (Mitchell grass) grasslands in Australia. A grazing study with sheep was conducte

Corrigendum to: Impacts of level of utilisation by grazing on an Astrebla (Mitchell grass) grassland in north-western Queensland between 1984 and 2010. 2. Plant species richness and abundance
Autor: David Phelps, D. M. Orr
Publikováno v: The Rangeland Journal. 36:309
The occurrence of interstitial species in Astrebla grasslands in Australia are influenced by grazing and seasonal rainfall but the interactions of these two influences are complex. This paper describes three studies aimed at determining and explainin

Managing for rainfall variability: impacts of grazing strategies on perennial grass dynamics in a dry tropical savanna
Autor: D. M. Orr, Peter J. O'Reagain
Publikováno v: The Rangeland Journal. 33:209
Rainfall variability remains a major challenge to sustainable grazing management in northern Australia with perennial grasses the key to the stability of the resources that maintain a sustainable grazing industry. This paper describes the dynamics of

Publikováno v: Animal Production Science. 50:284
Steer liveweight gains were measured in an extensive grazing study conducted in a Heteropogon contortus (black speargrass) pasture in central Queensland between 1988 and 2001. Treatments included a range of stocking rates in native pastures, legume-o
