%% Redefine \begin{abstract}...\end{abstract} and
%% define \begin{xabstract}[heading] ... \end{xabstract}
% First, we need a modified quotation environment
% with no indentation of the first line:
\newenvironment{uiom@noindent@quotation}
  {\list{}{%
     \listparindent = 1.5em\relax
     \rightmargin = \leftmargin
     \parsep \z@ \@plus\p@}%
     \item\relax}
  {\endlist}
% Then, we need an environment for formatting the abstract:
\newenvironment{uiom@abstract}[1][\abstractname]
  {\begin{center}\small\textsf{\textbf{#1}}\end{center}\uiom@noindent@quotation}
  {\enduiom@noindent@quotation}             
\renewenvironment{abstract}[1][\abstractname]
  {\cleardoublepage \pagestyle{empty}\vspace*{5\baselineskip}
    \uiom@abstract[#1]}
  {\enduiom@abstract}
% We also define an environment for a second abstract:
\newenvironment{xabstract}[1][\abstractname]
  {\par\vspace{3\baselineskip}\uiom@abstract[#1]}
  {\enduiom@abstract}


%% Define \begin{preface}
\newenvironment{preface}{%
  \chapter*{\prefacename}
  \markboth{\prefacename}{}
  }
  {}

%% Headers and footers:
