Eco-efficient criteria : sustainability
(3S Media, 2014-04)
There is an urgent need to apply cost-effective technologies and methods that deliver better and more sustainable performances.
Visual assessments of current pavement conditions in the stack areas of Berth 203-205 at the Durban Container Terminal-Pier 2
(Emerald Group, 2014-04)
The Durban Container Terminal is currently the biggest and busiest container terminal in Africa and handles about 2.7-million TEUs a year. DCT handles approx. 70% of South Africa’s containers and generates 60% of South ...
Difference of hydrodynamics for a VPE with and without mass transfer and effect of agitation level on extent of mass transfer
(The South African Journal of Chemical Engineers (SAJChE), 2013-12-29)
Liquid-liquid extraction offers an alternative separation technique, other than distillation, that uses a solvent for the separation of liquid constituents (Pratt, 1983). The vibrating plate extractor (VPE) is a mechanically ...
Capacity challenges facing civil engineering contractors in Kwazulu-Natal, South Africa
Insolvency maybe broadly defined as an inability of business entity to meet pending financial commitments. For a construction firm, such a situation creates conditions whereby a business entity is unable to fulfill its ...
Infrared heating assisted thermoforming of polypropylene clay nanocomposites
The objective of this work is to study the influence of nanoclay addition in PP sheet during infrared (IR) heating assisted thermoforming process. The effect of nanoclay on viscoelastic, friction and dimensional characteristics ...
Determining the best BRT for eThekwini
(3S Media, 2014-06)
BRT systems are fast becoming part of the South African urban landscape. In the first part of this two-part article, the authors set about defining BRT systems, looking at their history and examining configurations, factors ...
Melt blend studies of nanoclay-filled polypropylene (PP)–high- density polyethylene (HDPE) composites
The objective of this work is to study how the rheological factors of unfilled and nanoclay-filled HDPE– PP blend series influence the structure, morphology, and mixing characteristics. For this study, a series of HDPE–PP ...
Markers of hydration status in a 3-day trail running event
(Lippincott, Williams & Wilkins, 2013)
Objective: To examine the relationships between changes in static prestage and poststage measures of commonly used hematological and urinary markers of hydration status and body mass (BM) in participants in a 3-day trail ...
Design optimization of anisotropic pressure vessels with manufacturing uncertainties accounted for
Accurate optimal design solutions for most engineering structures present considerable difficulties due to the complexity and multi-modality of the functional design space. The situation is made even more complex when ...
Buckling and sensitivity analysis of nonlocal orthotropic nanoplates with uncertain material properties
Accurate estimates of the orthotropic properties of nano-materials are usually not available due to the difficulties in making measurements at nano-scale. However the values of the elastic constants may be known with some ...
