Stubble : Friend And Foe, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Several articles in this issue of the Journal of Agriculture discuss some of the important issues of stubble management. The articles are condensed from some of the papers presented at a stubble workshop at Geraldton in 1991.

Stubble Handling Machinery, Greg Haydon
Journal of the Department of Agriculture, Western Australia, Series 4
Farming in Western Australia, and in Australia, has undergone a revolution over the past 15 to 20 years. Two significant changes have been the cessation of ploughing to kill weeds, that is, the change from discs to tines, and the reduction in tillage through the use of agricultural chemicals. These have been important changes that have had conservation benefits. However, to handle stubble to best effect, further changes in machinery, newer machinery and combinations of machines will be needed. In this article, the author discusses current and possible future practces.
Stubble Handling Begins At Harvest, Ed Blanchard
Stubble Handling Begins At Harvest, Ed Blanchard
Journal of the Department of Agriculture, Western Australia, Series 4
Long stubble left in the paddock after harvest causes major difficulties at seeding time. To demonstrate the benefits of having short stubble at seeding, the Trayning Land Conservation District Committee created four stubble treatments at harvest in 1988 and sowed into these stubble treatments in 1989.
Measurement Of The Coefficient Of Thermal Expansion Of Superconducting Thin Films Using Powder X-Ray Diffraction, Biju Chandran, R. Calvin Goforth, S. Nasrazadani
Measurement Of The Coefficient Of Thermal Expansion Of Superconducting Thin Films Using Powder X-Ray Diffraction, Biju Chandran, R. Calvin Goforth, S. Nasrazadani
Journal of the Arkansas Academy of Science
The High Density Electronics Center (HiDEC) at the University of Arkansas, Fayetteville is developing the technology for High Temperature Superconductor Multi-Chip Modules (HTSC-MCM's). As part of this work, we are looking at the mechanical properties of HTSC materials. An important mechanical property which influences the mechanical integrity of the hybrid MCMis the coefficient of thermal expansion (CTE) of the HTSC films. As a first step in developing a procedure for the determination of the CTE of HTSC materials, the lattice parameters and the CTE of an alpha-alumina substrate have been determined by powder x-ray diffraction technique. An extension of this …

Journal of the Department of Agriculture, Western Australia, Series 4
To increase the rate of adoption of stubble retention farming systems the Grains Research and Development Corporation is funding a three-year project with the Farm Machinery Unit to develop low cost, stubble handling systems from harvest to seeding
