Seedling competition between native cottonwood and exotic saltcedar: implications for restoration
(2009)Altered hydrology of southwestern United States rivers has led to a decline in native cottonwood (Populus deltoides). Areas historically dominated by cottonwood have been replaced by invasive saltcedar (Tamarix chinensis). ... -
Normalizing and Converting Image DC Data Using Scatter Plot Matching
(2010)Remote sensing image data from sources such as Landsat or airborne multispectral digital cameras are typically in the form of digital count (DC) values. To compare images acquired by the same sensor system on different ... -
Using Spatial Structure Analysis of Hyperspectral Imaging Data and Fourier Transformed Infrared Analysis to Determine Bioactivity of Surface Pesticide Treatment
(2010)Many food products are subjected to quality control analyses for detection of surface residue/contaminants, and there is a trend of requiring more and more documentation and reporting by farmers regarding their use of ... -
Metal ion complexation in acetonitrile by upper-rim benzyl-substituted, di-ionized calix[4]arenes bearing two dansyl fluorophores
(2010)The influence of Li+ , Na+ , K+ , Rb+ , Cs+ , Mg2+, Ca2+, Sr2+, Ba2+, Ag+ , Cd2+, Co2+, Fe2+, Hg2+ , Mn2+, Pb2+, Zn2+ and Fe3+ on the spectroscopic properties of two dansyl (1- dimethylaminonaphthalene-5-sulfonyl) ... -
Sterically congested, geminal aryl-substituted, proton-ionizable sym-dibenzo-16-crown-5 lariat ethers: synthesis and alkali metal cation extraction
(2010)Three series of proton-ionizable sym-dibenzo-16-crown-5 ethers with sterically demanding 1- naphthyl, 2-naphthyl, and 9-phenanthryl geminal groups are synthesized and characterized. Variation of the proton-ionizable group ...
