Rotation-electronic interaction in the 3p-complex Rydberg state of water
… rotational energy levels in a p-complex Rydberg state of an asymmetric top molecule of symmetry C2v. The effective Hamiltonian used consists of the usual rigid rotor Hamiltonian augmented with terms representing electronic spin and orbital angular momentum effects. Criteria for assigning symmetry …

The Water to Which We Belong: Aqua nullius and Frames of Wara in a Black Oceania
… barriers modernity presents to the prospect of a new Oceania. Anchoring itself in the work of Epeli Hau’ofa it blends critical theory from the radical Black, Oceanian, French, and Indigenous traditions together to demonstrate the persistence of two structural logics of modernity – aqua …

Reflection of Debussy: A Comparative Analysis of Solo Marimba Works by Jacob Druckman and Richard Rodney Bennett
Jacob Druckman's Reflections' on the Nature of Water (1986) and Richard Rodney Bennett's After Syrinx II (1984) are two works for solo marimba that involve direct quotation and indirect stylistic appropriation from the music of Claude Debussy. Bennett composes a theme and variations using the flute …

The effectiveness of the water supply system at Chavani Village, South Africa
Most countries of the world are experiencing water crises because water as a natural resource is no longer as freely available as it used to be. The main contributing factor is technological advancement and associated economic expansion that have put a lot of pressure on water resources. The demand …

Biological Water: Properties and Role in Muscle Function and Development
Water is the most abundant substance on planet Earth and present in large part of our daily lives. Despite such abundance, liquid water still remains mysterious for we do not understand its structure. Similarly, biological systems are largely composed of water and life is believed to have …

Shock compression of water and solutions of ammonium nitrate
Modern mining explosives employ solutions of ammonium nitrate, where the solution is the oxidising component of a fuel/oxidiser mixture. This thesis is primarily concerned with the shock response of water and of aqueous solutions of ammonium nitrate. Of particular interest are the temperatures …

Transport and Structure in Fuel Cell Proton Exchange Membranes
Transport properties of novel sulfonated wholly aromatic copolymers and the state-of-the-art poly(perfluorosulfonic acid) copolymer membrane for fuel cells, Nafion, were compared. Species transport (protons, methanol, water) in hydrated membranes was found to correspond with the water-self …

Structure Property Relationships of Proton Exchange Membranes
The major challenge of the research was to characterize and develop concepts for establishing structure/property relationships between the functionality of the polymer backbone, the states of water and the membrane transport properties. Most of the hydrocarbon based random copolymers reported in …
