Polycyclic Aromatic Hydrocarbon Degradation By Novel Bacteria Isolated From Burrow Sediments Of Marine Benthic Macrofauna, Wai Ki Chung
Polycyclic Aromatic Hydrocarbon Degradation By Novel Bacteria Isolated From Burrow Sediments Of Marine Benthic Macrofauna, Wai Ki Chung
Electronic Theses and Dissertations
Polycyclic aromatic hydrocarbons (PAH) are significant environmental pollutants and represent a severe health threat. Many cosmopolitan areas including coastal environments are heavily impacted by PAH. This research investigates the isolation of PAH-degrading bacteria from burrow sediment of marine benthic macrofauna and their potential in bioremediation. Macrofaunal burrow sediment is biogeochemically distinct from bulk sediment and has high microbial activities. Samples were collected from a local uncontaminated cove and PAH degradation potential was measured by incubating sediment slurries with exogenous PAH. Burrow sediments from two polychaetes and a mollusc showed significantly higher PAH degradation potential than the bulk sediment. The degradation …
The Production Of Emotional Prosdy In Varying Severities Of Apraxia Of Speech, Steffany M. Van Putten
The Production Of Emotional Prosdy In Varying Severities Of Apraxia Of Speech, Steffany M. Van Putten
Electronic Theses and Dissertations
One mild AOS, one moderate AOS and one control speaker were asked to produce utterances with different emotional intent. In Experiment 1, the three subjects were asked to produce sentences with a happy, sad, or neutral intent through a repetition task. In Experiment 2, the three subjects were asked to produce sentences with either a happy or sad intent through a picture elicitation task. Paired t-tests comparing data from the acoustic analyses of each subject's utterances revealed significant differences between FO, duration, and intensity characteristics between the happy and sad sentences of the control speaker. There were no significant differences …
