Caractérisation multi-physique de la durabilité d'un sol traité à la chaux pour une application aux digues maritimes / M...
Dans le cadre de la construction de digues, le traitement à la chaux permet d'améliorer les performances des sols argileux en place pour éviter leur mise en décharge, et de réduire ainsi le coût économique et écologique du transport de matériaux d'apport de plus grande qualité. Des études antérieures ont montré que le traitement à la chaux augmente...
New insights into the termination of the African Humid Period (5.5 ka BP) in central Ethiopia from detailed analysis of ...
The termination of the African Humid Period in northern Africa has been described as abrupt, occurring within centuries, as well as gradual, in response to incremental decreases in summer insolation. This study examined the rapidity of the change in diatom assemblages over the period from 6.5 to 4.5 cal ka BP, in a core studied previously at a coar...

Hyperspectral imaging to evaluate the effect of irrigation water salinity in lettuce
Salinity is one of the most important stress factors in crop production, particularly in arid regions. This research focuses on the effect of salinity on the growth of lettuce plants; three solutions with different levels of salinity were considered and compared (S1 = 50, S2 = 100 and S3 = 150 mM NaCl) with a control solution (Ct = 0 mM NaCl). The ...
Calibration of CTD Oxygen data collected in the Coral sea during the 2012 Bifurcation cruise
An updated procedure for a CTD-oxygen calibration along with new data processing was applied to recent hydrographic cruise data in the Coral Sea during the Cruise "BIFURCATION" in September 2012. After a brief introduction with the scientific context (section 1), we describe the contents and acquisition models of hydrological and chemical data that...
