Abstract
The EU Water Framework Directive and Priority Substance Directive provide a framework to identify substances that potentially pose a risk to surface waters and provide a legal basis whereby member states are required to monitor and comply with environmental quality standards (EQSs) set for those substances. The cost and effort to continuously measure and analyse real world concentrations in all water bodies across Europe are high. Establishing the reliability of environmental exposure models to predict concentrations of priority substances is key, both to fill data gaps left by monitoring campaigns, and to predict the outcomes of actions that might be taken to reduce exposure. In this study, we aimed to validate the ePiE model for the pharmaceutical ibuprofen by comparing predictions made using the best possible consumption data with measured river concentrations. The results demonstrate that the ePiE model makes useful, conservative exposure predictions for ibuprofen, typically within a factor of 3 of mean measured values. This exercise was performed across a number of basins within Europe, representative of varying conditions, including consumption rates, population densities and climates. Incorporating specific information pertaining to the basin or country being assessed, such as custom WWTP removal rates, was found to improve the realism and accuracy of predictions. We found that the extrapolation of consumption data between countries should be kept to a minimum when modelling the exposure of pharmaceuticals, with the per capita consumption of ibuprofen varying by nearly a factor of 10.

Abstract
The reaction of the tetrametallic molecular loop [(CH3CN)6Mo2(OOC-C4H6-COO)]2[BF4]4 (1) (1 equiv.) with 2 equiv. of bis(diphenylphosphino)amine (dppa), 1,2-bis(diphenylphosphino)ethane (dppe) and bis(diphenylphosphino)methane (dppm) in propionitrile leads to the formation of the still tetrametallic complexes [(CH3CH2CN)4(X)Mo2(OOC-C4H6-COO)]2[BF4]4 (X = dppa (2), dppe (3), dppm (4)), also displaying a loop structure. All three complexes are characterized by NMR spectroscopy ((1)H, (11)B, (13)C{(1)H}, (19)F, (31)P{(1)H}), IR spectroscopy, elemental analysis, TG-MS measurements and UV-vis spectroscopy, compounds 2 and 3 additionally by X-ray single crystal diffraction.

Abstract
Zusammenfassung: Fragestellung: Das neu entwickelte krankheitsunspezifische Instrument zur Messung der Lebensqualität von Kindern und Jugendlichen (ILK, Mattejat et al., 1998 ) sollte hinsichtlich seiner Differenzierungsfähigkeit zwischen ambulanten und stationären psychiatrischen Stichproben überprüft werden. Methodik: 626 kinder- und jugendpsychiatrische Patienten aus regional unterschiedlichen Kliniken und Praxen wurde der ILK-Bogen vorgelegt. Die so gewonnenen Daten werden deskriptiv dargestellt und mit Hilfe logistischer Regressionen genauer analysiert. Ergebnisse: Während eine rein deskriptive Betrachtung zeigt, dass stationär behandelte Kinder und Jugendliche durchweg alle Lebensbereiche als belastender erleben, relativiert sich dieses Ergebnis durch die Regressionsanalyse. Hier zeigt sich, dass die deskriptiv gefundenen Unterschiede zwischen stationären und ambulanten Patienten teilweise auf Alters- und/oder Geschlechtseffekte zurückzuführen sind; in einigen Lebensbereichen jedoch erweisen sich die Unterschiede zwischen der ambulanten und stationären Stichprobe unter Berücksichtigung von Alter und Geschlecht als Kovariaten als durchaus substantiell. Schlussfolgerungen: Das ILK ist als effizientes ökonomisches Verfahren in der Lage, Lebensqualität in Abhängigkeit von dem Schweregrad psychiatrischer Störungen zu erfassen; darüber hinaus ist es sensitiv für Alters- und Geschlechtseffekte. Indem das ILK Bereiche mit verminderter Lebensqualität schnell und sicher identifiziert, bietet es Ansatzpunkte für Indikationsstellung, Therapieplanung und erste therapeutische Interventionen.

Abstract
Noticeable similarities were found in the psychosocial field by a comparison of a group of anorexia nervosa patients with a representative sample of normal controls. In particular, no confirmation could be found of the mother dominance coupled with the weak and frequently absent father, as postulated under the interactional model of anorexia nervosa. Empirical discriminate analyses of the role of individual family members are necessary.
