M.Tech. / The field of study is of a multidisciplinary nature and involves aspects of Mechanical Engineering Design, Materials Technology and Rock Mechanics. When rock bursts occur the rock mass moves at high velocities and the resulting impulsive load often leads to brittle fracture of fully grouted steel bars. It was therefore decided to develop a new product that would combine the strength of steel and the yielding ability of polyurethane. Such a product is envisaged to play an important role in the correct design of tunnel support. In optimizing the design of a polyurethane and steel combination, three important parameters have to be optimized simultaneously...

A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Occupational Therapy. Johannesburg, 2017 / Introduction: Lycra compression garments have been documented as beneficial in affecting spasticity in children with cerebral palsy but there is little research on the use of Lycra compression garments in adults with neurological conditions. Thus, the purpose of this study was to explore the effectiveness of Lycra compression garments on motor function and functional use of the upper limb, in patients with stroke. Methods: A randomised control design with a control or intervention group was used. Both groups received routine upper limb rehabilitation while the experimental group also received a custom Lycra compression garment worn for a minimum of six hours a day. Results: Change between an initial assessment and assessment at six weeks, was measured on the Fugl-Meyer Assessment of Motor Recovery (FMA) and The Disabilities of the Arm, Shoulder and Hand Outcome Measure (DASH). While both groups had significant improvement in upper limb movement, statistically significant differences for change in total motor function, wrist and hand movement and coordination were found when the experimental group and the control group were compared. Small differences in measurements of pain, passive range of motion, sensation and functional use of the upper limb were found between the two groups. Conclusion: Results indicate that Lycra compression garments may be beneficial in facilitating the return of movement in the upper limb in individuals with stroke. / MT2017

Environmental concerns have brought about a push to replace non-biodegradable products that are made from non-renewable resources. Investigations regarding use of wood fibers and other biomass as a raw material for biodegradable foams and sponges are an example of such a replacement. Foams made at least partially of biomass can be created using cellulose from wood fibers once the cellulose is converted into a fluid form. Polyurethane foams can be made from polyols containing as much as 50% biomass by combined dissolution of wood and starch. Sponges can be made completely from cellulose regenerated from a viscose rayon solution, and the effect of using wood fibers as reinforcement material within the cellulose matrix of such sponges was studied. The effect of fiber content and fiber length on absorbance, swelling, density, air to cellulose ratios, bound water, and tensile was determined.
