Responsiveness Of High Screenings And Commercial Cereal Grains To A Blend Of Xylanase And Phytase Enzyme Products, R J. Hughes, M S. Geier, J L. Black, A M. Tredrea, S Diffey, S G. Nielsen

Two experiments evaluated the apparent metabolisable energy (AME) values for cereal grains fed with and without a blend of xylanase and phytase enzyme products to broiler chickens. The first experiment involved 30 high screenings grains (10 wheats, 11 barleys, 3 triticales, and 6 sorghums). The second experiment involved 50 grains (20 wheats, 13 barleys, 3 triticales and 14 sorghums) donated by commercial companies throughout Australia. Each experiment included "connectivity" grains used in previous experiments that contributed to the AusScan near infrared reflectance (NIR) calibration database. The inclusion of "connectivity" grains (15 in Experiment 1 and 17 in Experiment 2) enabled ...


Research To Establish A Systematic Approach To Safe Welding Procedure Development Using Austenitic Filler Material For Fabrication Of High Strength Steel, Lenka Kuzmikova, John Norrish, Huijun Li, Mark Callaghan Jan 2011

Research To Establish A Systematic Approach To Safe Welding Procedure Development Using Austenitic Filler Material For Fabrication Of High Strength Steel, Lenka Kuzmikova, John Norrish, Huijun Li, Mark Callaghan

Faculty of Engineering and Information Sciences - Papers: Part A

High strength, thermo-mechanically treated steels often require very careful control of welding procedures to ensure freedom from hydrogen assisted cold cracking (HACC) in the weld metal and heat affected zone (HAZ) whilst avoiding undue loss of heat affected zone strength. In practice this leads to restricted operating envelopes and the requirement for rigorous procedure management. An alternative approach is the use of austenitic welding consumables but whilst this may be expected to expand the process parameter envelope its use is often restricted by adherence to procedures previously developed for ferritic consumables. The current paper describes the research undertaken to establish ...


Can Australia High Speed Rail Overcome It's Bumpy History?, Philip Laird Jan 2011

Can Australia High Speed Rail Overcome It's Bumpy History?, Philip Laird

Faculty of Engineering and Information Sciences - Papers: Part A

The Australian Government has released an "implementation" study for high speed rail (or HSR) on the east coast with a further study to follow. The proposal looks at corridors between Melbourne, Sydney and Brisbane. It includes the option of three-hour travel times between Sydney and Melbourne, with tickets costing around $100. With the projected price of the project starting at around $60 billion, and Australia's chequered history with HSR, it is not unreasonable to ask whether the project will commence. In this case, would Sydney to Newcastle take preference over Sydney to Melbourne?
