Abstract text goes here. References should be directly marked by [1]
etc., and equations typeset in Latex. For example:
\begin{equation}
E=\hbar \omega
\end{equation}
 The whole abstract should be
contained within one Letter page with 2.5cm margin on all sides.\\
At this point you are left with just about\\
\vspace{3.9cm}

this much text space, if you include the following figure.
\begin{figure}[ht]

% \rotatebox{270}{    % use this if figure needs to be rotated. 270 is the angle.
\includegraphics[height=60mm]{Figure1.eps} % change height if needed
% }                   %use this if figure needs to be rotated.

figure will appear in black and white in the printed Book of Abstracts.}
