Potential carbon losses from peat profiles: effects of temperature, drought cycles and fire
Download1992
Wein, R. W., Hogg, E. H., Lieffers, V. J.
Abstract: Global warming and the resultant increase in evapotranspiration might lead to lowered water tables in peatlands and an increase in fire frequency. The objective of this study was to investigate some of the potential effects of these changes on peat decomposition. Dry mass losses and...

Principal components of super-high dimensional statistical features and support vector machine for improving identification accuracies of different gear crack levels under different working conditions
Download2015
Tsui, Kwok Leung, Zuo, Ming J., Tse, Peter W., Wang, Dong
Gears are widely used in gearbox to transmit power from one shaft to another. Gear crack is one of the most frequent gear fault modes found in industry. Identification of different gear crack levels is beneficial in preventing any unexpected machine breakdown and reducing economic loss because...

Regulation of cold shock-induced RNA helicase gene expression in the cyanobacterium Anabaena sptrain PCC 7120
Download2000
Owttrim, George W., Chamot, Danuta
Expression of the Anabaena sp. strain PCC 7120 RNA helicase gene crhC is induced by cold shock.crhC transcripts are not detectable at 30°C but accumulate at 20°C, and levels remain elevated for the duration of the cold stress. Light-derived metabolic capability, and not light per se, is required...

The biosphere as an increasing sink for atmospheric carbon: estimates from increased nitrogen deposition
Download1993
Estimates of carbon uptake and storage based on global nitrogen deposition, C:N ratios for typical terrestrial ecosystems, and recent ecosystem-scale nutrient studies indicate that 1.0- 2.3 Gt C yr-1 of carbon storage may be stimulated by anthropogenically caused increases in nitrogen deposition...

Landon, Stuart, Smith, Constance E.
The growth of debt and deficits in developed countries has led many states to consider the adoption of fiscal rules. There is little evidence on the benefits of different types of rules. This study uses Monte Carlo techniques to examine the impact on welfare and government spending stabilization...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...
