One of the main challenges of desert rail operations is maintaining functional track and ballast. Professor Hannes Gräbe of the Chair in Railway Engineering at the University of Pretoria explains how ...

Bolted joints are among the most common structural elements in precision machinery. They are used because they are strong, serviceable and reliable. Yet, despite their prevalence, the moment stiffness ...

The rising prevalence of neck pain is believed to be associated with the sedentary trend of modern work, prolonged use of hand-held devices, and fundamentally, fatiguing mechanical loads. However, ...

There is growing interest in corneal biomechanics associated with demands for better precision in clinical diagnosis, treatment of corneal disease and corneal refractive surgery. The cornea possesses ...
