The distribution of organic bases in reverse phase liquid chromatography : a study of mechanisms

Creator:

Jayasinghe, Dudley Shelton

Abstract:

The distribution of hydrophobic ionogenic organic compounds (HIOC's) between aqueous and nonaqueous phases has been investigated. The HIOC's are aniline and methyl substituted anilines. The aqueous phases are methanol-water mixed solvents with varying pH and ionic strength. The nonaqueous phases are silica and alkyl derivatized silica with ethyl- (C-2), octyl-...

Spatio-temporal pattern analysis of managed forest landscapes : a simulation approach

Creator:

Li, Habin

Abstract:

This study dealt with research problems at the landscape level. The objectives of this thesis were to develop tools to study and characterize landscapes and to interface with a geographic information system (GIS), to evaluate landscape indices, and to examine development of forest cutting patterns under different cutting methods and...
