Ashworth, J. and Symonds, C. 2013. Simplified Microtox®bioassay for drilling waste disposal on lease soils in Alberta. Can. J. Soil Sci. 93: 109-111. The Microtox bioassay is specified in regulations ...governing drilling waste disposal in western Canada. Traditionally, four serial dilutions of waste-derived fluid are tested, to bracket the regulatory Pass threshold concentration. We find that an equally valid Pass/Fail result can be obtained from one test at the threshold concentration. The simplified method has labour and cost-saving advantages.
Abstract
This paper introduces arguments from Slavery, Capitalism, and Politics in the Antebellum Republic1 to suggest that the Civil War arose ultimately because of class-conflict between on the one ...hand, Southern slaves and their masters and, on the other, Northern workers and their employers. It does not, however, suggest that either in the North or the South these conflicts were on the point of erupting into revolution. On the contrary, they were relatively easily containable. However, harmony within each section (North and South) could be secured only at the cost of intersectional conflict, conflict which would finally erupt into civil war. The Civil War was a 'bourgeois revolution' not only because it destroyed slavery, an essentially precapitalist system of production, in the United States but also because it resulted in the enthronement of Northern values, with the normalisation of wage-labour at their core.

Ashworth, J. and Bullecer, I. 2012. A rapid bioassay to screen soils for toxicity of residual petroleum hydrocarbons. Can. J. Soil. Sci. 92: 901-904. The following 2-h procedure is proposed as a ...screen to indicate how soils contaminated with petroleum hydrocarbons (PHC) might perform in bioassays required for site remediation in Canada. Bio-available PHC in soil is extracted by aqueous cyclodextrin; a centrifuged extract portion is treated with amylase, then subjected to a standard Microtox® bioassay. Extract toxicity is correlated to available PHC content.

The Civil War should be seen as America's 'bourgeois revolution'. So argues Dr John Ashworth in this novel reinterpretation, from a Marxist perspective, of American political and economic development ...in the forty years before the Civil War. This book, the first of a two-volume treatment of slavery, capitalism and politics, locates the political struggles of the antebellum period in the international context of the dismantling of unfree labor systems. With its sequel, the volume will demonstrate that the conflict resulted from differences between capitalist and slave modes of production. With a careful synthesis of existing scholarship on the economics of slavery, the origins of abolitionism, the proslavery argument and the second party system, Ashworth maintains that the origins of the American Civil War are best understood in terms derived from Marxism.
