Fade to black : picturing mortality in contemporary popular film /

This thesis attempts to understand representations of death in contemporary popular film within a framework that posits mortality as a category of particular social and political importance for the way we understand both individual subjectivity and social responsibility in the postmodern cultural moment. It addresses concerns over the social organizing categories of time and space, and performs a sustained consideration of predominant themes related to the popular representation of death, such as contingency, existential.meaning, and temporal finitude. Death consciousness and social consciousness are shown to be not just intertwined, but also vitally dependent on one another, and the analyses undertaken are ultimately aimed at making these intersections explicit in order • l to think through their potential implications for challenging consumer capitalist hegemony and envisioning the possibility of progressive social change through the lens of our mortality.

Studies on the insecticide - nematicide-oxamyl and its quantitative determination by gas chromatographic method

Ox amyl , an insecticide/nematicide with the chemical name; methyl ~'. ~·-dimethyl-~-(methylcarbamoyl)oxy-l-thiooxamimidate, and its major degradation compound; oxime or oximino compound, methyl ~',~'-dimethyl-~-hydroxy-l-thiooxamimidate were studied in this work. NMR and mass spectrometry were utilized in the structural studies. An attempt was made to explain the fragmentation patterns of some major peaks in the mass spectra of oxamyl and oxime. A new gas chromatographic method for the detection and determination of submicrogram levels of intact oxamyl using a electron-capture detector was developed. The principle of this method is to produce a derivative which is highly sensitive to an electron-capture detector. The derivative described is dinitrophenyl methylamine( DNPMA ) • Experimental conditions such as pH , reaction temperature , reaction time, the amount of reagent ( Dinitrofluaro benzene) etc. were thoroughly investigated and optimized. This method was successfully applied to the determination of oxamyl residues in tobacco leaves and soil. Throughout this J9D:oject , thin layer chromatography was also used in the separation:and clean up of oxamyl and oxime samples.
