Challenges in the Measurement of the Volume of Phases for HPLC Columns by Victor David, Jana Petre, Serban C. Moldoveanu

“…The evaluation of the time spent by a solute exclusively in the mobile phase (dead time) is of fundamental interest for the interpretation of the retention data and obtainment of thermodynamic parameters for the HPLC process. This parameter depends on the volume occupied by the mobile phase and on the volume of the effective stationary phase from the HPLC column, and the measurement of these volumes poses a real challenge. …”

Tous vulnérables ? le diagnostic de vulnérabilité aux aléas de l’érosion : un outil pour l’action collective by Marie Liégeois, Paul Arnould, Stanislas Wicherek

“…We thus wish to work in this way, and try to diagnose the vulnerability of agricultural land and built-up area in front of erosion to improve the collective action around the muddy flood risk.Starting from the idea that risk is as well a natural than a cultural fact, we wished to integrate the subjectivity and traditional knowledge of the population (farmer especially) in the parameters of the diagnosis. This posture, applying the bottom-up approach, poses an original question about scales: scale of data-gathering at first, but also scale of temporal and space validity of such a methodology.…”
