The hippocampus is essential for spatiotemporal cognition. Sequences of neuronal activation provide a substrate for this fundamental function. At the behavioral timescale, these sequences have been shown to occur either in the presence of successive external landmarks or through internal mechanisms within an episodic memory task. In both cases, activity is(More)
Rhizobial isolates that were obtained from both surface and deep soil samples in the Sahelian and Sudano-Guinean areas of Senegal (West Africa) under Acacia albida trees were compared with representative strains of known rhizobial species and genera. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of proteins was used to determine the(More)
Since the 1970s, increase in fire frequency has been observed in all European Mediterranean regions. The objectives of this study were 1) to determine the effects of wildfire frequency on the recovery at short and long-term of soil chemical and microbial properties and 2) to identify the mechanisms underlying the recovery of these sites properties. Soils(More)
The assessment of physico-chemical properties in forest soils affected by fires was evaluated using near infrared reflectance (NIR) spectroscopy coupled with chemometric methods. In order to describe the soil properties, measurements were taken of the total organic carbon on solid phase, the total nitrogen content, the organic carbon and the specific(More)

iii oreword istributed interactive simulation (DIS) is the linking of aircraft, tank, and other military simulators in diverse locations so that the crew of one simulator can " see, " operate with, " shoot " at, or be " destroyed " by the other vehicles being simulated. Command structures can also be simulated. This allows forces to practice and train in(More)
The principal aim of this research was to determine the influence of an increasing wildfire history on the recovery at short and long term of soil organic matter (SOM) composition and microbial properties. The contemporary wildfire events (since 1950) were recorded for 27 plots located on the siliceous part of the French Mediterranean region (Maures(More)
