AbstractAbstract
[en] A new European directive concerning ionising radiation treatment of foodstuffs has been recently adopted, although National laws may continue to be applied at least until 31 December 2000. A brief updated review dealing with the legal and analytical aspects of food irradiation is presented. The legal status of the food irradiation issue presently in force in Italy, in the European Union and in the USA is discussed. Some of the most used and reliable analytical methods for detecting irradiated foodstuffs, with special reference to standardised methods of European Committee of Standardization, are listed

Una nuova direttiva sull'irraggiamento degli alimenti e' stata adottata nel marzo 1999 dall'Unione Europea, sebbene le normative dei singoli Stati Membri possano restare in vigore fino al 31 dicembre 2000. Viene presentata una breve ma aggiornata rassegna sugli aspetti legislativi correlati a quelli analitici riguardanti gli alimenti irraggiati. Vengono comparate le normative in materia attualmente in vigore in Italia, nell'UE e negli USA, riportando l'elenco degli alimenti che possono venire trattati con radiazioni ionizzanti e le dosi di radiazione massime applicabili. Vengono inoltre presentati i metodi analitici di controllo piu' utilizzati e affidabili, con particolare riferimento a quelli entrati ufficialmente in vigore come standard europeiPrimary Subject

AbstractAbstract
[en] We give statistical definitions of the length, l, of a loose prime knot tied into a long, fluctuating ring macromolecule. Monte Carlo results for the equilibrium, good solvent regime show that (l) ∼ Nt, where N is the ring length and t ≅ 0.75 is independent of the knot type. In the collapsed regime below the theta temperature, length determinations based on the entropic competition of different knots within the same ring show knot delocalization (t ≅ 1).
