the impacts of perennial vegetation practices and soil depth on soil water dynamics as compared to row crop system; (iv) to evaluate the effects of long-term perennial management and cropping systems, landscape positions, and the distance from the base of a...
Membrane interactions with membrane type 1 matrix metalloproteinase
(University of Missouri--Columbia, 2018)
Membrane type 1 matrix metalloproteinase (MT1-MMP) is essential to a myriad of extracellular activities including tumor cell migration and angiogenesis. At the cell surface, MT1-MMP is a major factor in the proteolysis of receptors, growth factors...

Determination of the scale of fluctuation of cone penetration test data obtained from an alluvial site in Missouri
(University of Missouri--Columbia, 2018)
To account for uncertainty in geotechnical projects, knowledge of the uncertainties should be understood. Many sources of uncertainties can be reduced with increased sampling and good practices, but due to the nature of geomaterials, inherent...
