    Es wird eine Methode fiir eine schnelle approximative Bestimmung von Aluminium in reinen Aluminatlaugen beschrieben. Die Methode beruht auf der volumetrischen Bestimmung derjenigen Athanolmenge die notwendig ist, um in Aluminatlaugen Bildung einer ersten Trilbung von Dauer etwa einer Minute zu verursachen. Dauer der Bestimmung etwa 20 Minuten. Fehler ilbersteigen selten ± 3%. Mit der gleichen Methode kann die Ausscheidung von Aluminiumoxydhydrat aus ilbersattigten Aluminatlaugen ,bis zum Gleichgewicht verfolgt werden

    Traumatic experience has overall far reaching consequences on personality. In particular, it has significant impact on teenagers that are just approaching the phase of solving their identity problems. This research examines the relation of traumatic experience and attitude towards the future in two groups of adolescents. The first group consists of 20 adolescents-refugees from the East Slavonia that were settled in Rijeka area with their parents during the last six years. The second group consists of 20 adolescent’s local inhabitants that were influenced by the war only indirectly. Results show significant difference between refugees and non-refugees in expressed interpersonal trust, frustration tolerance, and formation of close contacts, adaptability, precaution, bitterness, and social desirability. Both groups show increased depression, pessimism and poor self-control. This might be considered as general characteristic of society in war

    Time-dependent multi-orbital mean-field for fragmented Bose-Einstein condensates

    The evolution of Bose-Einstein condensates is usually described by the famous time-dependent Gross-Pitaevskii equation, which assumes all bosons to reside in a single time-dependent orbital. In the present work we address the evolution of fragmented condensates, for which two (or more) orbitals are occupied, and derive a corresponding time-dependent multi-orbital mean-field theory. We call our theory TDMF(nn), where nn stands for the number of evolving fragments. Working equations for a general two-body interaction between the bosons are explicitly presented along with an illustrative numerical example.Comment: 16 pages, 1 figur
