- The old city of Fez, Morocco, classified as Heritage of Humankind by the UNESCO, is subject to an integrated rehabilitation plan running over 15 years. The plan aims at restoring and preserving the economy, cultural value, and social heritage of the old city. The study follows a system dynamics approach to describe and analyze the rehabilitation plan in order to identify the strengths and defects of the plan. This study shows that while the plan is giving relatively satisfying results over the short and medium terms, it is unlikely to attain long term sustainability.

- The crystal symmetry of epitaxial Tl-2201 films on LaAlO3 and SrTiO3 substrates is investigated by X-ray diffraction. In the case of Tl1.85Ba2CuO6 film, a φ-scan of the (1 1 10) reflection showed four diffraction peaks separated by 90.00±0.02°. A 2θ-scan of the same reflection exhibited a single peak. 2Θ−ω- and φ-scans of the corresponding reflection in Tl2.04Ba2CuO6 show splitting and broadening of the diffraction peaks indicating an orthorhombic distortion. The effect of errors in film alignment on the φ-scan and 2Θ−ω-scans is discussed. A periodic function, δ=a+bsin(ω−φ), was used to correct the φ-scan measurements. The influence of lattice mismatch between film and substrate on the structural symmetry of the films is discussed.
