In magnetic resonance imaging, contrast agents are employed to enhance the signal intensity. However, current commercial contrast agents are hindered by a low relaxivity constant. Dendrimers can be employed to create higher molecular weight contrast agents which have an increased relaxivity due to a lower molecular rotation. [...]

22 p, 1.6 MB Structural and paleomagnetic evidence for non-rotational kinematics of the South Pyrenean Frontal Thrust at the western termination of the External Sierras (southwestern central Pyrenees) / Oliva Urcia, B. (Universidad de Zaragoza. Departamento de Ciencias de la Tierra) ; Casas, A. M. (Universidad de Zaragoza. Departamento de Ciencias de la Tierra) ; Pueyo, E. L. (Oficina de Proyectos de Zaragoza IGME. Departamento de Geología y Geofísica del subsuelo) ; Pocoví Juan, Andrés (Universidad de Zaragoza. Departamento de Ciencias de la Tierra)
The definition of the structure and kinematics of the South-Pyrenean Frontal thrust, to the west of its westernmost outcrop in the External Sierras is the goal of this work. The methodology used is based on the construction and restoration of three balanced cross-sections. [...]
