Integrating vitrinite reflectance, rock-eval pyrolysis, flourescence microscopy and palynology of the Athabasca oil sands, Kearl Lake area, northeastern Alberta

Three cores from the Kearl Lake Oil Sands area within the Athabasca deposit of northeastern Alberta have been analyzed to understand the thermal history of the McMurray and Clearwater formations of the Lower Cretaceous Mannville Group. The approach involves the integration of vitrinite reflectance (VR), Rock-Eval pyrolysis, fluorescence microscopy, and palynology. Mean VR varies between 0.21 and 0.43% Ro and indicates thermally immature levels equivalent to the rank of lignite to sub-bituminous coal. Although differing lithologies have influenced VR to some extent (i.e., coals and bitumen-rich zones), groundwater influence and oxidation seem not to have measurably altered YR. Rock-Eval analysis points to Type III/IV kerogen, and samples rich in amorphous organic matter (ADM) show little to no fluorescence characteristics, implying a terrestrial source of origin. Palynology reveals the presence of some delicate macerals but lack of fluorescence and abundant ADM suggests some degradation and partial oxidation of the samples.

Investigating Microbial Trace-fossils and Abiotic Alteration in Hydrovolcanic Tuffs of the Fort Rock Volcanic Field, Oregon

Microbial ichnofossils in volcanic rocks provide a significant record of subsurface microbes and potentially extraterrestrial biosignatures. Here, the textures, mineralogy, and geochemistry of two continental basaltic hydrovolcanic deposits - Reed Rocks and Black Hills - in the Fort Rock Volcanic Field (FRVF) are investigated. Methods include petrographic microscopy, micro and powder X-ray diffraction, SEM/BSE/EDF imaging, energy dispersive spectroscopy, stable isotopes, and X-ray fluorescence. Petrographic analysis revealed granular and tubular textures with biogenic morphologies that include terminal enlargements, septate divisions, branching forms, spiral filaments, and ovoid bodies resembling endolithic microborings described in ocean basalts. They display evidence of behaviour and a geologic context expressing their relative age and syngenicity. Differences in abiotic alteration and the abundance/morphotype assemblage of putative microborings between the sites indicate that water/rock ratio, fluid composition and flux, temperature and secondary phase formation are influences on microboring formation. This study is the first report of reputed endolithic microborings in basalts erupted in a continental lacustrine setting.

Indenture of deed of bargain and sale between Samuel Rock of Crowland Township and Samuel Street of the Town of Niagara

Indenture of deed of bargain and sale between Samuel Rock of Crowland Township and Samuel Street of the Town of Niagara for 1 acre in Lot no. 179 in the Town of Niagara – instrument no. 13070. A memorial of this record was made on Feb. 21, 1856, List B, Folio 169. An envelope addressed to Joseph Woodruff, Clerk of the Peace and postmarked Jan. 1857 was included with this document, July 17, 1840.

La Bible coulée dans le rock. Fragmentation et reconstruction du texte biblique dans la musique rock

Dans ses entretiens, George Steiner considère la musique rock et le heavy metal comme l’espéranto international des jeunes de notre époque (Steiner, Entretiens, p. 91). Or, cet espéranto porte une dimension religieuse manifeste, entre autres à travers l’usage fréquent d’images et de textes bibliques souvent passés au broyeur des guitares et des voix vociférantes. On peut se demander quelles figures construisent les fragments qui en résultent, souvent irrévérencieux voire scandaleux pour plusieurs. À travers les violences que le rock et surtout le métal infligent au texte biblique, faut-il voir des attaques contre la Bible et contre Dieu, comme le croient plusieurs chrétiens, ou, au contraire, un respect profond de la dynamique de ce texte et un usage légitime de celui-ci ? Davantage portée par la seconde hypothèse, ce texte vise à identifier les usages et les fonctions religieuses de la Bible dans la musique rock.

Brooklyn, capitale du rock indépendant : médiations, réseaux et le train « L »

Brooklyn est depuis quelques années un épicentre de la musique indépendante aux États-Unis. En utilisant la démarche ethnographique, l’auteur s’intéresse au rôle des médiateurs dans la définition du réseau socio-musical de la scène « indie » de Brooklyn à New York. Il met en relief la façon dont historiquement, le quartier brooklynois de Williamsburg est devenu un lieu important d’établissement des Brooklyn est depuis quelques années un épicentre de la musique indépendante aux États-Unis. En utilisant la démarche ethnographique, l’auteur s’intéresse au rôle des médiateurs dans la définition du réseau socio-musical de la scène « indie » de Brooklyn à New York. Il met en relief la façon dont historiquement, le quartier brooklynois de Williamsburg est devenu un lieu important d’établissement des musiciens alternatifs. Il aborde la façon dont les hipsters, comme communauté, font appel à différentes pratiques pour contourner le rapport d’infériorité avec les étiquettes majors. Il s’intéresse aussi au « do it yourself » ainsi qu’au rôle de New York dans le milieu musical mondial. Finalement, il s’intéresse aux médias qui définissent et structurent le milieu de la musique indépendante de Brooklyn.

Age-Dependent Properties of Acid & Alkaline DNases in Chick Brain

Acid and alkaline DNase activities in partially purified preparations from young and old chick brain were measured. The specific activity of acid DNase from old brain was lower by about 50% than that of enzyme from young brain , whereas alkaline DNase exhibited only marginal difference in activity of the two preparations . Study of various properties, viz. heat-stability and effect of exogenous compounds like Mg=', Hgl', Zn=', PHM B , on these enzymes revealed that while acid DNase in old brain is more susceptible to heat and heavy metal ion inhibition , alkaline DNase is devoid of any age-dependent variation in its properties.

Alkaline protease production by marine fungus engyodontium BTMFS 10

The thesis entitled “Alkaline Protease Production by Marine Fungus Engyodontium BTMFS 10”.Proteases are the single class of enzymes, which occupy a pivotal position with respect to their application in both physiological and commercial filed. Protease in the industrial market is expected to increase further in the coming year. The current trend is to use microbial enzymes since they provide a greater diversity of catalytic activities and can be produced more economically. Main objective of theses studies are the optimization of various physicochemical factors in the solid state fermentation for the production of alkaline protease enzyme, characterization of the enzyme, evaluation of the enzyme for various industrial application. The result obtained the during the course of theses study indicate the scope for the utilization of this study Marine Fungus E.
