The new IMX formulations are replacing old formulations at a rapid pace, but IMX has a relatively unknown fate and ecosystem toxicity.The proposed research will examine IMX fate in poplar trees, poplar tissue cultures, and poplar endophytic bacteria.To date, it is unclear how nutritional deprivation during development affects disease resistance and immunocompe-tence at later stages.
The performance of new hypothesis tests for stationarity and space-time separability based on these new Torgegrams will be investigated.
The combined effect of these efforts will be to make statistically sound spatiotemporal prediction and trend estimation possible on stream networks.
One or two sequences will be sampled intensively for radiometric age and isotopic climatic indicators.
,000 Fate Studies of Insensitive Munitions Explosives in Poplar and Methlyobacteria: Dr. Just, Department of Civil & Environmental Engineering, The University of Iowa The environmental fate of 2,4-dinitroanisole (DNAN), 3-nitro-1,2,4-triazole-5-one (NTO), and 1-nitroguanidine (NQ) in new insensitive munitions explosives (IMX) formulations is an emerging global issue.
Full-scale remediation will be necessary for military training and testing sites around the world, and this research will confirm the viability of the energy-efficient and economical technique of tertiary treatment by poplar trees, as opposed to costly techniques such as incineration or landfilling of contaminated soils.
,896 Seeing the urban forest for the trees: An assessment of the relationships between urban forests and biodiversity, carbon storage, and carbon sequestration: Dr.The proposed research will develop new models for nonstationary and spatio-temporal processes on stream networks.It will also modify or extend the Torgegram — a graphical tool for characterizing spatial dependence on stream networks — for use with nonstationary spatio-temporal data.The results of this work will help us better understand how the effects of poor nutrition during development is translated into health effects later in life, and will pave the way for more in-depth investigations of honey bee health and immunity.,000 Modeling Nonstationary Spatio-temporal Data on Stream Networks: Dale L. Hogg Professor of Statistics, Department of Statistics and Actuarial Sciences, The University of Iowa Statistical methods for spatio-temporal prediction and temporal trend estimation have long been available for environmental variables on Euclidean domains, but are not yet available for variables on stream networks.In Iowa, as around the world, impacts of intense anthropogenic land-use on native habitats underscore a need for sustainability efforts to be informed with truly integrative biological knowledge.
