Duality, the Methodology of Shooting a Documentary as a One-Man Crew

This thesis will discuss Duality, a long-form documentary about artistic nude models who also create art involving the nude female form. This thesis will discuss the inspiration for the film, as well as the deciding factors that made me choose this as the topic for my thesis documentary. This thesis will also cover the process and methodology of shooting a documentary as a one-man crew, beginning with the process of preproduction, then the principal photography of the documentary, followed by the editing and postproduction process, and finally premiering the final film

Novel Polyfluorinated Compounds Identified Using High Resolution Mass Spectrometry Downstream of Manufacturing Facilities near Decatur, Alabama

Concern over persistence, bioaccumulation, and toxicity has led to international regulation and phase-outs of certain perfluorinated compounds and little is known about their replacement products. High resolution mass spectrometry was used to investigate the occurrence and identity of replacement fluorinated compounds in surface water and sediment of the Tennessee River near Decatur, Alabama. Analysis of legacy Per- and polyfluoroalkyl substances (PFASs) revealed a marked increase in concentrations downstream of manufacturing facilities, with the most abundant compounds being perfluorooctanesulfonate (PFOS), perfluorobutanesulfonate (PFBS), and perfluorooctanoic acid (PFOA) as high as 220 ng L^–1, 160 ng L^–1, and 120 ng L^–1, respectively. A series of nine polyfluorinated carboxylic acids was discovered, each differing by CF₂CH₂. These acids are likely products or byproducts of a manufacturing process that uses 1,1-difluoroethene, which is registered to a manufacturing facility in the area. Two other predominant compounds discovered have structures consistent with perfluorobutanesulfonate and perfluoroheptanoic acid but have a single hydrogen substituted for a fluorine someplace in their structure. A polyfluoroalkyl sulfate with differing mixes of hydrogen and fluorine substitution was also observed. <i>N</i>-methyl perfluorobutane sulfonamidoacetic acid (MeFBSAA) was observed at high concentrations and several other perfluorobutane sulfonamido substances were present as well
