Direct and indirect nitrous oxide emissions from controlled release and conventional fertilizers applied to potatoes in coarse textures soil.
… grown. Polymer coated controlled-release ureas (PCU) have shown promise in reducing NO3 - leaching, a groundwater quality concern, and may potentially also reduce emissions of N2O, a greenhouse gas with nearly 300 times the warming potential of carbon dioxide. However, comparisons of multiple …

Baeyer-Villiger Oxidation of 1,7- & 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione
… (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction …

The cognitive function of the DMN and its role in consciousness
… on a core region of the DMN the precuneus (PCu), which was found to be functionally divided into distinct subregions during cognitive control task execution. The results support the hypothesis that the PCu mediates the interaction between the internally-oriented DMN and externally-oriented …

Energy based visualisation of a Brayton cycle power conversion unit for the purpose of condition monitoring
… a basic Brayton cycle power conversion unit (PCU) is used as a case study to determine the suitability of an energy-based approach to FDI. The PCU is completely characterised by an attributed graph matrix in terms of energy and exergy. Exergy was identified as being part of the energy …

Studies in regiospecific oxidation reactions of 1-methyl-pentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione.
… dilactone, was synthesized by reacting 1-methyl-PCU-8,11-dione with m-chloroperbenzoic acid in 1:2 molar ratio. 6-Methyl-1,4,4a,8a-tetrahydro-1,4-methanonaphthalene-5,8-dione was converted into the corresponding exo-6,7-monoepoxide via treatment with 30% aqueous hydrogen peroxide. Epoxidation of …

The relationship between cupric ion activity and the toxicity of copper to phytoplankton
… pseudonana (clone 3H) copper was inhibitory at pCu values below 10.7 (i.e. cupric ion activities above 10-10.7) with total growth inhibition occurring at pCu values below 8.3. The relationship between growth rate inhibition and cupric ion activity was not a simple hyperbolic relationship as was …
