Noise reduction during diffusion tensor imaging of infants by Jordaan, Johannes Petrus

“…In this work, noise reduction was achieved by implementing digital low-pass filters to reduce high-frequency harmonics of the standard trapezoidal gradient waveforms, focusing on the EPI readout portion of a diffusion tensor imaging (DTI) sequence. …”

Chloride penetration in concrete: evaluation of rapid conductivity methods and development of a service life prediction model for marine conditions by Surana, Saarthak

“…On the relationship between the apparent chloride diffusivity and chloride conductivity index (CCI), it was found that the time dependent variation of microstructural penetrability could explain the time dependent reduction in apparent diffusivity. …”

The race to zero: emission reduction strategies in the sugarcane growing industry in southern Malawi by Cuff, Amy

“…Findings suggest that governance within the sugarcane growing industry's emission reduction agenda has elements of polycentricity, and is characterised by the chaos and complexity of numerous actors working through self-governance with diffusion and linkages towards the achievement of a common goal but lacks coordination or collaboration between actors. …”

The mobility of oxygen containing species (OCS*) over Pt-based catalyst surfaces: Impact on the oxygen reduction reaction (ORR) activity by Gambu, Thobani G

“…Edge sites were found to adsorb oxygen containing species strongly. Consequently, the diffusion barriers of O* and OH* from edge sites towards terrace sites were much higher than the diffusion on the terraces and even higher than the activation barrier for reaction in the ORR. …”

Synthesis, characterisation and engineering of thin films of ZSM-5 on alumina, quartz and sand supports by Msimang, Velaphi Zakhele

“…The pX activity of the alumina film (i.e., the zeolite film supported on alumina beads), increased with increasing film thickness which corresponded to deactivation caused by migration of Na + ions. Although, diffusion limitations were present, the observed ortho-xylene selectivity enhancement and activity reduction with increasing film thickness did not conform to that predicted by the reaction-diffusion model. …”

Mechanical and structural behavior of as-built and post treated Ti6Al4V lattice structures fabricated by selective laser melting (SLM) by Salem, Hala Ahmed

“…Results revealed the decomposition of α՝ depending on the heating temperature used, which was reflected in the reduction of the yield strength. Additionally, reduction in ductility was observed as well in all the treated condition due to the oxygen diffusion which reduced the strain at fracture. …”

Service life extension of reinforced concrete structures using hydrophobic impregnation by Sohawon, Haris

“…In terms of the bulk diffusion test, chloride ingress in the treated concrete mixes was suppressed and lower chloride surface concentration (Cs) and apparent chloride diffusion coefficient (Da) were recorded. …”

Assessing the influence of crack width on the durability potential of cracked concrete using the durability index approach by Kanjee, Janina Prakash

“…The cracked specimens were monitored for carbonation (accelerated carbonation) and chloride ingress (bulk diffusion), while the uncracked ones were monitored for durability parameters (OPI, WSI & CCI) after 8 and 16 weeks of exposure. …”
