Froth stability of coal flotation in saline water
, 2014 The objective of this study was to identify a practical solution to mitigating over-stable froth problems in fine coal flotation in saline water. The effect of coal particle size, water quality and chemical reagents which can be manipulated in flotation ...

International Journal of Urban and Regional Research, EarlyView.Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly

Journal of Forensic Sciences, EarlyView.Abstract Postmortem decomposition changes of bodies in aquatic environments may offer valuable insights into the postmortem submergence interval (PMSI) for medicolegal death investigators. However, the effects of immersion on the onset of such changes are poorly understood.

Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis
Computer Graphics Forum, EarlyView.In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40

An investigation into the role of DTP as a co-collector in the flotation of a South African PGM ore
, 2011 The primary aim of this study was to investigate, using a combination of batch flotation and ToF-SIMS experimental techniques, whether a collector-collector synergistic interaction between SIBX and diethyl DTP will result in significantly enhanced copper,

JCMS: Journal of Common Market Studies, EarlyView.Abstract Literature on policy debates often analyses cases involving either a single or two policy fields, which typically result in stable equilibria, manifesting either as outright rejection of policy proposals, successful institutional change or the entrenchment of divisions into a deadlock.
