Ballanco had been invited to be a presenter by Prof. John Swaffield, Head of the Dept. of Building Engineering at Heriot-Watt University and one of the foremost plumbing researchers in the world.
According to a conference attendee, “Julius was the only American invited to present a paper at the conference. There was a great deal of interest in his topic and his presentation was exceptionally well received.”
The paper was originally presented at the ASPE Bi-Annual Convention in Indianapolis in 1998. It was then modified and published as a feture article in the October 1998 issue of PME.
