I have been told that my folliwers have not heard from me for some time. However, I do not think I have any followers. I am not seeking employment, as I retired in 2009 from my position as lecturer in Inorganic Chemistry at what was then AIT (now part of TUS). Recently, I was invited to join GainRep, so I accepted, though I do not really need it. But if my experience may be of any use to anyone, I am willing to help.
