Plain wire fencing for pastoral lands

The need to fence for efficient livestock control was recognised early in the history of the pastoral industry in Western Australia. Fence design, materials and layout have all undergone many changes since the 1880s. Modern fences have 4 or 5 strands of high tensile light gauge wires with post spacings up to 50m, and strains up to 4000m. These modern fences contain less material and are faster to erect than traditional fences, yet they provide an equally good, if not superior, barrier. The happy coincidence of strength and cost effectiveness will be apparent through this manual

Response by Stylosanthes hamata and S. scabra to phosphate on three soils in the north-Kimberley of Western Australia

Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years

Discrete derived categories I: homomorphisms, autoequivalences and t-structures

Discrete derived categories were studied initially by Vossieck (J Algebra 243:168–176, 2001) and later by Bobiński et al. (Cent Eur J Math 2:19–49, 2004). In this article, we describe the homomorphism hammocks and autoequivalences on these categories. We classify silting objects and bounded t-structures
