The Solar Tracker has been developed at the Cape Peninsula University of Technology. It is an efficient mechanism for positioning a solar collector to track the sun. This device is adept to intermittent adjustment of the position of a solar energy collection surface, ensuring that the surface

The inverse Class-F power amplifier (PA) comprises an appropriately biased GaN active device, input matching network, and output wave-shaping and matching network. The novel design of the wave-shaping and output matching network ensures minimal overlap of the drain voltage and current waveforms, and

According to the present invention, there is provided a process for extracting mucilage from succulent plants, in particular, the cladodes of the Opuntia ficus-indica or the leaves of the Aloe barbadensis or Agave Americana the process comprising the steps of: a) providing a source of cladodes or

Biofiltration is the filtration of contaminated water using organic material to capture and biologically degrade contaminants. A biofilter comprises inorganic or organic filtering media such as rock, slag, sand, glass beads, peat or wood chips on which a biofilm develops when wastewater flows over
