Polyaniline And Its Derivatives For Environmental Analysis., Atogho Jude Abia
Electronic Theses and Dissertations
Electrooxidation has been used to deposit thin film polyaniline as well as its derivative - thin film poly (ortho-phenylenediamine) (POPD) and poly (meta-phenylenediamine) (PMPD) on carbon electrodes, which are subsequently used to monitor the environmental heavy metal ions (Hg2+, Pb2+ ,Cd2+) through a rather unusual "blocking" of anodic stripping for these metals. Using Hg2+ as a model, its cyclic voltammogram for a modified glassy carbon electrode with the resultant polymer shows an enhanced cathodic peak that increases linearly with the analyte ion concentration. POPD also exhibits unique selective detection for organic species. Acetaminophen and …
An Examination Of The Prison Environment: An Analysis Of Inmate Concerns Across Eight Environmental Dimensions., Andrew Ryan Bradford
An Examination Of The Prison Environment: An Analysis Of Inmate Concerns Across Eight Environmental Dimensions., Andrew Ryan Bradford
Electronic Theses and Dissertations
This study was undertaken to better understand inmate concerns of the prison environment across 8 dimensions. The 8 dimensions examined in this study were activity, emotional feedback, freedom, privacy, safety, social, structure, and support. To determine the importance of these dimensions among inmates, secondary data were used in an attempt to replicate and validate the findings from Wright's (1985) study which used a prison environment inventory instrument to assess inmate concerns. The secondary data consisted of an inmate sample of 1,054 taken from 30 prisons of minimum, medium, maximum and close security across the states of Tennessee, Kentucky, and Ohio. …
