The 40-m high Raviege dam, built in 1957 and operated by Electricité de France (EDF), is located in South West of France, on the Agout River. The discharge capacity of the two existing gated spillways located in the center of the dam is not sufficient regarding the updated design flood. One of the solutions studied is a project combining the use of the reservoir storage capacity and a new Piano Key Weir spillway on top of the dam, beside the existing gates, aims to increase the dam safety towards floods. Scale model tests have been carried out at the Laboratory of Engineering Hydraulics of the University of Liege to optimize the PKW design and precisely characterize its discharge capacity. The scale model study also focused on the design of energy dissipation structures downstream of the PKW. This rehabilitation project is depicted in the paper, with focus on the PKW design. [less ▲]

Within the framework of development of PKW use for rehabilitation as well as for new dam projects, the development of efficient design methods is essential. Currently, the design of PKW projects is done by mean of scale modeling, on the basis of a geometry initially designed based on the general knowledge issued from idealized experimental studies and former PKW buildings. This paper presents a systematic method for PKW preliminary design. The method is based on extrapolation of existing experimental results to develop one or several available project designs, regarding the project constraints (discharge, reservoir levels, available space, …). The model permits then the optimization of the design depending on technical and economical interests (increase of the safety, decrease of the maximal head, limiting the weir dimensions, limiting construction costs, …). The application of the method to a new large dam project is presented, highlighting the interest of the method for the optimization of the design depending on technical and economical interests.

The economic losses caused by post-harvest pathogens of apple and pear can still reach 25 %. There is currently an increasing demand to develop sustainable methods to control these post-harvest pathogens. Biocontrol agents are interesting candidates to answer this demand. Nevertheless, their commercial development is sometimes hampered by a low or non-reliable efficacy comparing to fungicide treatments. Fundamental research on the mode of action of the BCA and of its ecological fitness could help to overcome that phenomenon. This chapter reviews the progresses made during two decades to understand the mode of action and the ecological niche of two BCA, Pichia anomala strain K and Candida oleophila strain O. These advances required the combination of various methodologies (in vitro and in situ) and techniques (microbiology, microscopy, genome characterization, transcriptome, proteome, gene disruption. . .) which are summarized here. Importantly, the practical impact of these discoveries to improve the efficacy of the biopesticide is also highlighted. [less ▲]

Laser tunability from 10 to 21 mm is obtained by use of an optical parametric oscillator based on a KTP crystal followed by a difference-frequency stage with a CdSe crystal. An all-solid-state picosecond Nd:YAG oscillator mode locked by a frequency-doubling nonlinear mirror is used for synchronous pumping. [less ▲]

This paper will examine how two different media, painting and photography, respond inrepresenting the same theme: the theme of religion and transcendence. Four different culturalobjects will be studied in this light: 1) religious painting, 2) artistic photography with a religioustheme, 3) devotional photography that is transformed into holy images, and 4) the Russian icon. Wewill analyse the filtering effect of these two media in the representation of religious themes. We willseek to explain why the religious theme in painting has been able to assume a sacred dimensionwhich, by contrast, seems unachievable in contemporary artistic photography. [less ▲]
