    Notes: [Auszug] Fig. 1 Family tree showing the inheritance of the gene responsible for the production of the non-functional serum Clq. This condition appears to behave as an autosomal recessive in which both affected siblings, II 1 and II 2, are homozygous for the defective gene, and both parents and sibling II4 ...

    Notes: [Auszug] The valve mechanism can be conveniently considered as a cycle comprising four distinct phases: opening, quasi-steady, deceleration and reversed flow. The first three phases occupy about 15 per cent, 55 per cent and 30 per cent of systole respectively. The cusps present negligible obstruction to the ...

    Notes: [Auszug] If the amount of DNA in the somatic diploid cell nucleus is known, and if total tissue DNA can be extracted, cell numbers can be readily calculated, for it has been shown that the diploid amount of DNA in the cell nuclei is constant for a particular species2. This fact is the basis of a number of ...

    Regional Setting, Geology, and Paragenesis of the Centennial Unconformity-Related Uranium Deposit, Athabasca Basin, Saskatchewan, Canada (2014)

    Description: The Centennial unconformity-related uranium deposit represents the first significant uranium mineralization along the Snowbird tectonic zone in the south-central part of the Athabasca Basin. The deposit is associated with a steeply WNW-dipping contact between the Virgin Schist Group and mylonitic granite of uncertain age. Virgin Schist Group rocks in the deposit area include phyllites, impure quartzite, and quartzite. Medium- to coarse-grained microcline "augen" porphyroclasts characterize the granite. The quartzite, being resistant to weathering, forms a paleotopographic high flanked by a paleotalus which formed prior to Athabasca Group sedimentation. Diabase, petrographically and geochemically similar to the 1.27 Ga Mackenzie dikes, intrudes the mineralized trend along brittle structures in the basement rocks and Athabasca Group. A detailed paragenetic study of the deposit area reveals a protracted history that is related to the episodic reactivation of brittle structures and associated fluid movement along this significant structural corridor. Retrograde metamorphism converted biotite to chamosite at temperatures between 335° to 350°C. Weathering caused the breakdown of microcline and the dissolution of quartz prior to erosion and deposition of the Athabasca Group, which started at about 1750 Ma. Compaction and diagenesis resulted in quartz overgrowths and development of a diagenetic clay assemblage of illite and sudoite at temperatures between 150° and 200°C, which was broadly synchronous with primary mineralization. Clinochlore, euhedral quartz, carbonate, and pyrite was developed after the intrusion of the diabase under reducing conditions, primarily at temperatures between 270° to 320°C. Uranium remobilization and alteration of uraninite to coffinite appears to have taken place after the emplacement of the diabase dikes. Kaolinite and uranophane form last in the paragenetic sequence and probably form at relatively low temperatures.
