In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios.

Στην παρούσα εργασία προσδιορίστηκε το περιεχόμενο λίπος με την μέθοδο εκχύλισης Soxhlet σε εξήντα (60) δείγματα επεξεργασμένων τροφίμων, εκ των οποίων τα έντεκα (11) αναλύθηκαν και ως προς τη σύσταση των λιπαρών τους οξέων με αέρια χρωματογραφία. Τα τρόφιμα συλλέχθηκαν από διάφορες περιοχές της Ελλάδας με σκοπό κυρίως την αξιολόγηση της ποσότητας των περιεχομένων trans λιπαρών οξέων. In this particular thesis, total amount of fatty acids from sixty(60) samples was determined using the Soxhlet method. Eleven(11) of all samples were further elaborated in order to determine the trans fatty acids using Gas Chromatography. Samples were randomly chosen from places all over Greece with primary purpose of specifying the content in trans fatty acids

We are just beginning a two year research project on the management of nuclear risk issues, paying particular attention to environmental, financial and safety issues. One aspect that concerns us is to avoid the assumption that any future accident will be similar to a past accident. In the cases of Chernobyl and Fukushima, it was possible both to evacuate the local population to impose a substantial exclusion zone, and we recognize that for many potential accidents this would be the case. But for some nuclear plant, it may not be so because of the large number of local inhabitants or because of some key industrial or societal infrastructure. We would like to take the opportunity of the ISCRAM conference to discuss this issue with a wide audience.
