Molecular imaging of spatio-temporal distribution of angiogenesis in hindlimb ischemia model and diabetic milieu
In the current thesis, spatio-temporal evaluation of the endogenous angiogenic response to ischemia was perfomed. After vascular occlusion, ischemic angiogenesis is an important reparative mechanism and can ameliorate the outcome of ischemic disease. Diabetic foot ulcers affect almost 15% of …

The Spatial and Temporal Distribution and Management of Tomato Bacterial Wilt on Virginia's Eastern Shore
… ESV over three growing seasons to determine the temporal and spatial distribution of this disease in commercial tomato fields. Plants were assessed at approximately one-week intervals throughout the growing seasons and the incidence of bacterial wilt for each individual plant was recorded. A …

Using Bayesian Hierarchical Models to Study the Spatial and Temporal Distribution of Mammals in Serengeti National Park
… variables while accounting for spatial and temporal dependence. We develop a join statistic to measure the spatial dependence of data. Then we create a metric that compares the spatial clustering that exists when the data is compared at different time intervals. This shows how much the …

Assessing the Spatial and Temporal Distribution of MTBE and BTEX Compounds in Lake Lewisville, Texas February 1999 - February 2000
The spatial and temporal distribution of Methyl Tertiary-Butyl Ether (MTBE) and BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) compounds were assessed in a multipurpose reservoir, Lake Lewisville, Texas between February 1999 and February 2000. Concentrations of MTBE ranged from 0.0 - 16.7 mg/L. …

Assessing the spatial and temporal distribution of nature-based solutions benefits. Combining economic valuation, participatory GIS and stakeholder perspectives
This thesis investigates how the spatial and temporal dynamics of nature-based solutions (NBS)—in particular the distribution of their benefits across space and time—shape their economic valuation, stakeholder perceptions, and public acceptability. While NBS are known to deliver benefits that vary …
