    Eight crude oils (Southern Louisiana Petroleum, H Coal Syncrude, H Coal Fuel Oil, SRC II, Exxon Donor Solvent Liquid, Occidental in situ Shale Oil, Paraho Shale Oil and Geokinetics in situ Shale Oil) were distilled into, or have been received, as four fractions for analysis and screening for biological (mutagenicity and tumor initiating) activity. Results of selected analytical tests have been obtained on the undistilled crude oils and the fractions. Salmonella typhimurium mutation assay and an accelerated tumor initiation-promotion test have been run on the undistilled crude oils and the fractions. Low boiling (naphtha) fractions of all eight materials showed little or no mutagenicity or skin tumor initiating activity by the two tests used. The higher boiling fractions (gas oils and residues) and the crude oils themselves were mutagenic and exhibited tumor initiation activity. The coal derived fractions were more active by both tests than the shale oil samples, the latter were similar to the petroleum controls. Few differences were apparent in biological activity between coal derived samples of equivalent boiling range among the various coal liquefaction processes, except that the SRC II naphtha sample showed a degree of acute toxicity through skin absorption not exhibited by the other samples. Generally the results agreed closely for the various samples between the salmonella mutation assay with activation and the skin tumor initiation test

    Four crude oils (H Coal-Fuel Oil Mode, Occidental in situ Shale Oil, Exxon Donor Solvent Liquid, and SRC II) which were distilled into four fractions (naphtha, mid-distillate, gas oil and residue) for analysis and biological screening testing during the last report period were tested for mutagenicity by the Ames test and for tumor initiating activity by an initiation/promotion (skin painting) test. Substantial agreement exists between Ames and skin painting results. Low boiling naphtha fractions of the 4 crude oils showed little or no mutagenicity or tumor initiating activity by the two tests used. The higher boiling fractions (gas oils and residues) and the crude oils themselves were mutagenic and exhibited tumor initiation activity. The coal derived fractions were more active by both tests than the shale oil fractions

    Four crude oils (Southern Louisiana Crude Petroleum, H. Coal Syncrude, Paraho Crude Shale Oil, and Geokinetics in situ Shale Oil) have been distilled into four fractions (naphtha, mid-distillate, gas oil, and residue) for analysis and biological (mutagenicity and carcinogenicity) screening testing. Results of selected analytical tests have been obtained on the original crude oils and the fractions. Ames tests and initiation/promotion tests have been started on the original crude oils and the fractions. Four additional synthetic crude oils (Exxon EDS, SRC II, H Coal Fuel Oil, and Occidental In Situ Shale Oil) are being obtained for a second similar series of tests to be started in approximately four months

    Four crude oils (Southern Louisiana Crude Petroleum, H Coal Syncrude, Paraho Crude Shale Oil and Geokinetics in situ Shale Oil) which were distilled into four fractions (naphtha, mid-distillate, gas oil and residue) for analysis and biological screening testing during the first report period were tested for mutagenicity by the Ames test and for tumor initiating activity by an initiation/promotion (skin painting) test. Substantial agreement exists between Ames and skin painting results. Low boiling fractions of the 4 crude oils showed little or no mutagenicity or tumor activity by the two tests used. The higher boiling fractions (mid gas oils and residues) and the crude oils themselves showed positive mutagenicity and tumor initiation activity. The coal derived fractions were more potent by both tests while the shale oil fractions showed greater activity than the petroleum fractions but considerably less than the coal syncrude

    Geographies of postsecular rapprochement in the city

    No full text
    <p>This paper explores the emergence of urban spaces of partnership between people of faith and those of no religious faith who come together to offer care, welfare and justice to socially excluded people. The activities of such groups are understood in terms of adjustments to the secularization thesis pointing to the possibilities of a series of emerging geographies relating to postsecular rapprochement and different forms of reterritorialization in the city. In particular, the accounts of postsecularism by Klaus Eder and Jurgen Habermas are used to explain both how the hushed-up voice of religion is being released back into the public sphere in some settings, and how the assimilation and mutually reflexive transformation of secular and theological ideas may represent crossover narratives around which postsecular partnerships can converge around particular ethical precepts and practical needs. Taking the particular example of Christian religion in western Europe, the paper traces both how a critique of secularism has led to some instances of contemporary political expression underpinned by theological precepts that are converted into practical ethics, and how a greater propensity among the Christian faith to explore faith-by-praxis has fuelled increased activity in the public sphere. Not all such activity can be regarded as postsecular, but emergent spaces of postsecular partnership in the city offer possibilities for new, perhaps liminal, geographies of resistance that cannot be explained away as simply the incorporation of religious capital into neoliberal governance. The possibilities of mutually transformative possibilities in these partnerships open both politics and faith up to processes of poststructural reterritorializing as part of the faith-in-practice of postsecularism.</p>
