Description:This training programme is directed towards the provision of a basic course that instructs in an easy to understand manner those concepts that are absolutely necessary in order to comprehend and make a contribution in the work place. All theoretical aspects of the learning process will be supported by specially designed low power experiments. Reports of experimentation would form the bulk of the assessment procedure.

Course Duration:10.0 Days
