Oil spills of unknown origin, so-called “mystery” spills, occur routinely in rivers, open water, and navigable coastal waterways. The natural resources damage (NRD) liability associated with even a small volume of oil released into the environment warrants that a thorough chemical characterization of the spilled oil be conducted by agencies and potentially responsible parties (PRPs). Chemical fingerprinting methods have played an important role in the identification of mystery oil spills. These methods fall into two categories, viz., qualitative and quantitative. The qualitative approach relies upon visual comparison of various chromatographic fingerprints obtained by GC/FID and GC/MS analysis of spill and candidate source oils and are represented ASTM methods. The quantitative approach relies upon measurements of the concentrations (relative or absolute) of dozens of diagnostic chemicals, typically PAHs and biomarkers, and a subsequent statistical or numerical analysis of various diagnostic parameters calculated from these concentrations. The quantitative approach is represented by the revised Nordtest methodology. The quantitative approach is preferable for most oil spill investigations since the means of interpretation are objective, whereas the ASTM methods are subjective. Quantitative fingerprinting data are particularly important when the mystery spill and source oils are qualitatively similar and are required when mystery spills may include mixed sources or prespill oil signatures. 相似文献

Abstract This article notes the virtual exclusion of women from accounts of the ‘Renaissance’ within late nineteenth-century British Quakerism. A focus upon a hitherto neglected figure, Matilda Sturge (1829-1903), author and Quaker minister, reveals her long-standing involvement in the aspects of Quakerism crucial to the Quaker Renaissance and as an active participant in the debates which preceded it. But Matilda Sturge also was active in the Home Mission movement, a project of Evangelical Friends, which has generally been represented as antithetical to the liberals of the Quaker Renaissance. Foregrounding women's experience introduces new perspectives on late nineteenth-century British Quakerism. 相似文献

Abstract. This article attempts to explore the relationships between Canadian provinces and American states in a systematic, empirical fashion. The constitutional context within which provinces and states may legitimately interact is far from definitive, particularly on the Canadian side. However, the relative lack of precise constitutional guidance has not prevented the development of a complex mélange of official relations between provinces and states. These trans-border relationships may be classified according to their degree of formality and their function. Oddly enough, there appears to be a larger number of formal as opposed to informal relations. Functionally, province-state contacts may be categorized as regulatory, third-party, protective-environmental, public works, and public service. In addition, the impact of geography and time are considered as conditioning factors. A number of illustrative examples are given, particularly province-state co-operation in pollution control and in the suppression of forest fires. In conclusion, the article finds that province-state trans-border co-operation is natural and involves no challenge to the primacy of the respective federal governments in their conduct of foreign relations. However, the broader significance of these subnational official ties remains to be assessed. Sommaire. Cet article tente d'examiner, dune façon empirique et systématique, les relations entre les provinces canadiennes et les Etats américains. Le contexte constitutionnel à l'intérieur duquel les provinces et les Etats peuvent entretenir des relations officielles est loin d'être définitif, surtout au Canada. Néamoins, ce manque relatif d'un régime juridique précis n'a pas empêché les Etats et les provinces de développer un mélange complexe de liens officiels. On peut classifier ces relations province-état selon leur degré de formalité et selon leur fonction. Singulièrement, il semble y avoir un nombre plus grand de relations formelles que de relations informelles. D'un point de vue fonctionnel, on peut catégoriser les liens province-état comme étant régulatoires, de tiers parti, reliés à l'environnement, aux travaux publics et à la fonction publique. De plus, l'auteur constate le rôle important que jouent la géographie et le temps dam les contacts province-état. Quelques exemples illustratifs sont donnés, particulièrement touchant la coopération province-état dam les domaines de la protection de l'environnement et de la suppression des feux, de forêts. Pour conclure, l'article constate que les relations province-état sont naturelles et qu'elles n'impliquent aucun déft à la primauté du gouvernement fédéral de chaque pays concernant les relations étrangères. Cependant il faut attendre les événements pour analyser les contacts province-état dans une plus grande perspective. 相似文献

Middle distillate fuels are used in civilian and military jet engines, on-road (truck and bus) and off-road diesel (diesel-electric locomotives, heavy equipment, and farm machinery) engines, marine diesel engines, nonaviation gas turbines, and domestic and commercial furnaces. As such, these fuels are common environmental contaminants that may arise from multiple sources. The considerable liability associated with these fugitive fuels requires that their source(s) be defensibly determined. In this paper we describe the “chemical fingerprinting” features of middle distillate fuels that can be used in assessments of their source(s) in the environment. A case study in which railroad (off-road) diesel fuel #2 could be distinguished from nonrailroad fuels (e.g., on-road diesel fuel #2, fuel oil #2, and/or fuel oil #1) in Mandan, North Dakota, is presented. 相似文献

The study of diplomacy has traditionally focused on relationships and interactions between the governments of nation-states, empires, principalities, and similar politicies. This state-centric view has been challenged in recent times by scholars who have sought to take into account the proliferation of different types of actors in the international arena. This paper address diplomacy between governments and non-state economic entities, a broad category of bodies extending from multilateral economic institutions such as the World Bank, International Monetary Fund, and GATT/World Trade Organization to consultative and knowledge-generating bodies such as the World Economic Forum and International Chamber of Commerce. 相似文献
