Spatial and temporal variability of soil freeze-thaw cycling across Southern Alberta, Canada
Freeze-Thaw Soil Temperature Agro-Ecosystem Modeling Regional Climate Soil Science
2013/3/5
Soil freeze-thaw cycles play an important role in all aspects of agro-ecosystems, such as crop productivity, the evolution of the soil matrix, including trace-gas emissions. In regions that experience...
Changes in the near-surface soil freeze-thaw cycle on the Qinghai-Tibetan Plateau
Freeze–thaw cycle Permafrost Qinghai-Tibetan Plateau Mountain cryosphere Climate warming Microwave remote sensing Trend analysis
2013/9/2
Changes in the near-surface soil freeze–thaw cycle on the Qinghai-Tibetan Plateau (QTP) were detected using daily soil freeze/thaw states derived from Special Sensor Microwave/Im...
A new soil freeze/thaw discriminant algorithm using AMSR-E passive microwave imagery
soil freeze/thaw status microwave radiometer discrimination analysis AMSR-E
2013/9/2
The soil freeze–thaw controls the hydrological and carbon cycling and thus affects water and energy exchanges at land surface. This article reported a newly developed algorithm for distinguishing the ...
Post-thaw bovine spermatozoal quality estimated from fresh samples
Post-thaw bovine spermatozoal quality fresh samples
2009/2/12
Comparisons were made among flow cytometrically quantified populations of fresh and cryopreserved bovine spermatozoa, tri-stained with fluorophores rhodamine 123 (R123), 5- (and 6-) carboxy-4',5'-di...
