%% Abstract:
%% use of unnumbered sections and two-column page layout
%% makes the abstract just another section
%\renewenvironment{abstract}{\section{Abstract}}{}

%% Page headings
%%  The first page contains the heading
%%    "12th Australasian Heat and Mass Transfer Conference
%%     The University of Sydney
%%     8--9 July 2021"
%%  So we define a new page style called afmchead and
%%  invoke it in the \maketitle.  The incantation is
%%  a modification of that found in Kopka & Daly, Appendix C.3.2
%%  The other pages contain no heading.
