Fires are an inherent part of the Australian environment. They cannot be prevented, but the risks they pose — to life, health, property and infrastructure, production systems, and to environment values — can be minimised through systematic evaluation and strategic planning and management. Fires have a fundamental and irreplaceable role in sustaining many of Australia’s natural ecosystems and ecological processes, and they are a valuable tool for achieving many land management objectives. However, if they are too frequent or too infrequent, too severe or too mild, or mistimed, they can erode ecosystem ‘health’ and biodiversity and compromise other land management …

Electrooxidation has been used to deposit thin film polyaniline as well as its derivative - thin film poly (ortho-phenylenediamine) (POPD) and poly (meta-phenylenediamine) (PMPD) on carbon electrodes, which are subsequently used to monitor the environmental heavy metal ions (Hg2+, Pb2+ ,Cd2+) through a rather unusual "blocking" of anodic stripping for these metals. Using Hg2+ as a model, its cyclic voltammogram for a modified glassy carbon electrode with the resultant polymer shows an enhanced cathodic peak that increases linearly with the analyte ion concentration. POPD also exhibits unique selective detection for organic species. Acetaminophen and …

This environmental assessment I assessment of effect examines in detail two alternatives: no action and the National Park Service preferred alternative. The preferred alternative considers rehabilitation of the roadway and associated structures on either side of Route 10 (Zion-Mt. Carmel Highway) tunnel. The road work would primarily occur on the east side of the tunnel in a 0.25-mile segment beginning at the east tunnel entrance. Modifications on the east side of the tunnel would include slurry sealing the road surface and scaling rock slopes on both sides of the road; re-configuring two parking areas; creating a painted center median with …

This paper describes the creation of Microcosm, a low cost wireless sensor network test-bed within a controlled environment to facilitate WSN experiments in three dimensions, with an emphasis on executing sensing-related experiments. The design of the sensing hardware, software, support tools and the experimental environment itself are given. Issues related to the design of this configuration are discussed, with the potential pitfalls and eventual solutions alike given. Finally, current and future uses for the test-bed are listed.
