Seismic performance of steel-reinforced concrete composite columns of older and modern construction
Published 2018“…Retrofitting shear deficient SRC columns under high axial loads (>40%) and flexure deficient columns under high axial loads (higher than the balanced load, i.e. compression controlled failure) experiencing moderate to strong ground shaking seems inevitable.…”

Mechanical Structure Design and Analysis of Focal Plane Unit (Fpu) for Earth Observation (Eo) Payload
Published 2023“…In this dissertation we perform the design of a focal plane unit using Solid Works 3D CAD modelling software. To validate the mechanical performance of our design Finite Element Analysis (FEM) analysis needs to be performed on every mechanical element with application of launch and environmental loads. …”

A study on ground improvement using a combination of stone and concrete columns
Published 2019“…This technique mainly uses naturally occurring materials as its load transferring medium. However, stone columns have some constraints because of the loose interactions between their aggregates which can lead to uncontrolled settlements, especially in soft soils. …”

Patterns of mobility, and the effect of mobility on viral suppression and retention among postpartum women living with HIV in South Africa
Published 2021“…Patterns of self-reported mobility between delivery and the 4 year measurement visit were examined. Logbinomial models were used to explore the association between mobility (moving in the 3, 6 or 12 months prior to the study visit) and i) viral suppression (viral load (VL) ≤50 and ≤1000 copies/mL measured at the 12 month and 4 year measurement visit) and ii) retention in care (based on routine medical record data at approximately 12 months and 4 years postpartum). …”

Characterization of and risk factors for HIV-1 resistance mutations following first line antiretroviral failure in the southern African private sector
Published 2017“…Variables included in analyses were age, gender, province, WHO stage at time of resistance testing (HIVDR), duration of ART at HIVDR, prior monotherapy or dual therapy, viral load and CD4 count prior to starting ART, viral load and CD4 count at HIVDR, duration that the viral load was >400 copies/ml prior to HIVDR and HIV subtype. …”
