262+ \begin{itemize}
263+\item \textcolor{red}{Diesel-generated nanoparticles} raise concerns
264+ about their effects on human health and
265+ environment.
266+\item \textcolor{red}{Legislation} regulating diesel-vehicle particulate \textcolor{red}{mass}
267+ emissions (EURO1,2,3,4,\emph{etc}\dots), but particle number
268+ distributions may be a better metric (especially for health effects).
269+\item Evaluate \textcolor{red}{effect of sampling and experimental conditions}
270+ on measured particle number distributions emitted from light/heavy duty vehicles $\Rightarrow$ \textcolor{red}{PMP}.
271+\item Exploratory research as an experimental and theoretical study of the
272+ \textcolor{red}{dynamics of non-volatile (\textcolor{red}{PMP}) particles emitted from diesel
273+ light-duty vehicles} (emphasis on nanoparticle agglomeration).
274+ \item Experiments performed at the \textcolor{red}{Vehicle Emission LAboratories}
275+ (VELA) at Ispra.
276+% \item Investigation of diesel-nanoparticle aggregate structure, collisions and
277+% mobility via \textcolor{red}{Langevin} simulations.
278+% \item Aerosol processes: \textcolor{red}{convection, agglomeration, thermophoretic and
279+% diffusional transport}
280+% \item Emitted agglomerates are \textcolor{red}{fractal} objects. How
281+% to estimate their fractal dimension from limited experimental information?
