Phosphate-rich rock from Rum Jungle, N.T., was tested as fertilizer against Christmas Island rock phosphate dust (CIRPD) and superphosphate in two pot and three field experiments. The Rum Jungle material had little short-term value as fertilizer, but the long-term residual effects were about 60 per cent of those of CIRPD. Calcining at 450�C gave a marked improvement in short-term response in pots, but had little effect in a long-term field experiment. Pelletting the Rum Jungle material with sulphur and Thiobacillus ('biosuper') increased its effectiveness in the field at the end of the second year to the equivalent of that of superphosphate.

The long- and short-term effects of hydraulic loading were investigated in a pilot packed tower bioreactor used for denitrifying a groundwater used for drinking water. Field experiments were conducted at hydraulic loading rates of 3.63 and 7.24 m3/hr/m2. The long-term (21 day average) performance of the denitrification reactor and the short-term response (48 hour) to regular air scour are reported here. In summary, an increase in hydraulic loading resulted in a long-term increase in the half-order denitrification rate constant, so that, on average, nitrate removal was maintained in the 5.2 m tower. At the lower hydraulic loading rate (3.63 m3/hr/m2) denitrification performance in the first 48 hours after air scour was maintained; however at twice the hydraulic loading, several days were required to restore the biofilm performance to long-term average levels.

Abstract The return of foreign fighters and their families to the European Union has mostly been considered a security threat by member States, which consequently adopt repressive measures aimed at providing an immediate, short-term response to this perceived threat. In addition to this strong-arm approach, reintegration strategies have also been used to prevent returnees from falling back into terrorism and to break down barriers of hostility between citizens in the long term. Amidst these different strategies, this paper seeks to identify which methods are most desirable for handling returnees.
