Polysulfone mixed matrix membranes with biosynthesis nanoparticles: enhancement of interface compatibility and antibacterial membrane seperation process
This study investigates the effect of biosynthesis silver nanoparticles (bio-AgNPs) structure towards PSf membranes performance. The addition of bio-AgNPs in the membrane formulation was aimed to improve antibacterial properties and interface compatibility of the polymer mixed matric membrane. In …

A geochemical investigation of ground water and soils affected by evaporation pond seepage, at the Namakwa Sands Mineral Seperation Plant(MSP)
Evaporation ponds are used for treating wastewaters in arid regions worldwide. Namakwa Sands an Anglo American plc operation, mines heavy minerals along the semi arid West Coast of South Africa. An acid effluent is generated during treatment of these heavy minerals. The effluent is neutralized and …

Calculation of the axial charge of a heavy nucleon in Lattice QCD
… m[pi] = 0.450 GeV. Three different source-sink seperations were used, tsink = [12a, 14a, 16a]. For each timeslice seperation signal we perform a correlated x2 fit and obtain the following values for gA: 0.551, 0.564 and 0.556. The unrenormalized value value for gA is extracted taking the limit …

Interacting non-Abelian anyons in an exactly solvable lattice model
… spectral evolution as a function of the vortex seperation, we unambigously identify the zero modes with the fusion degrees of freedom of non-Abelian anyons. To calculate the non-Abelian statistics, we show how the vortex transport can be implemented through local manipulation of the couplings. …

The Impact of The Partition Crisis on Cavan and Monaghan,1914-1926.
… i.e. 1923-1925, witnessed the creation of fiscal seperation between North and South. The impact of this economic partition and the concurrent closure of border roads is analyized. Specific attention is given to the border towns which suffered the most from the creation of the customs posts. This …

Investigation of injection moulding for novel drug delivery systems. An investigation into the use of injection moulding to produce pharmaceutical dosage forms and to understand the relationship between materials, processing conditions and performance, in particular drug release and stability
… detailed understanding of crystal habits, phase seperation and surface crystallisation. The significant effect of the stress conditions on the rate of shrinkage was observed where, higher shrinkage tendency of a HPMCAS IM system was observed compared to Soluplus® IM systems. The extruded pellets …

Multiscale Analysis of Macromolecular Systems
… diffusion coordinates (DCs). For systems with a seperation of timescales, the first few DCs are sufficient to characterize the slow processes of the system. Reaction rates computed along the 1st DC are in remarkable agreement with the rates measured directly from simulation. LSDMap has been …

Blending of polyethylene materials for pipe applications
… levels studied, illustrating that there was no seperation of the polyethylene phases. Fracture analysis of pipe failures showed variations between the blends, except for a MDPE additive which had similar molecular characteristics to the base resin. Some of the blends fracture surfaces were found …
