Comparative 30‐day life cycle assessment of bladder drainage strategies
Objective To identify the most environmentally sustainable urinary drainage strategies commonly used to manage bladder outlet obstruction and also to highlight actionable levers for reducing the footprint of urinary drainage in clinical practice. Materials and Methods We conducted a comparative life cycle assessment of three urinary drainage strategies

Permian–Jurassic tectonism produced cooling ages preserved in Mesozoic strata of the Dzereg and Dariv basins. Thermal modeling indicates mid‐Cretaceous and late Cenozoic basin inversion and cooling synchronous with bounding‐range exhumation, supporting a long‐lived source‐to‐sink relationship and persistent inherited relief since the Jurassic ...

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA
New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

Cathodic deposition of uranium
Journal of Electroanalytical Chemistry, 1977Abstract Cathodic depositions of uranium were carried out at controlled pH from a number of solutions containing the metal salt, and a complexing agent. A reducing agent was also present to prevent oxidation of the element. The current density ranged from 50 to 200 mA cm−2. The purity of the deposited uranium was better than 99.7%.

The Deposition of Uranium in Bone
Health Physics, 1969Abstract Quantitative autoradiography was employed to study the distribution of two isotopes of uranium in the bones of dogs. 232U or 233U was injected intravenously as the nitrate into adult dogs, and the animals were sacrificed serially at times ranging from 2 to 72 days after injection.

Geometallurgy of uranium deposits
Minerals Engineering, 2011Mineralogical controls exert significant control over the extraction of uranium from its ores. Uranium speciation, associated mineralogy, deportment and uranium mineral availability are all factors for consideration when assessing leachability. This study presents data from laboratory uranium extractions undertaken on several contrasting uranium ores ...

The deposition of uranium-sesquicarbide
Journal of Nuclear Materials, 1974Abstract Deposition of U2C3 from an aic-melted mixture of UC + UC2 ( 7.0 ± 0.1 wt % carbon) was examined primarily by the change of electrical resistivity as a function of time at fixed temperatures: 1370, 1440, 1575 and 1650°C. The rate constant of the reaction UC + UC2 → U2C3 was investigated in detail.
