Transport électronique et Verres de Spins

Transport électronique et Verres de Spins  The Anderson localization in quasi one dimensional systems What is Anderson localization? In 1958 Anderson [111] proved that diffusion in random lattices can disappear due to the quantum interferences. For a three dimensional system,...

Minéralisations cuprifères supergènes dans le district Centinela, désert d’Atacama, Chili Fission track analyses  Principles  The low-temperature thermochronology fission track method, proposed by Price and Walker (63), is based on the spontaneous fission of natural uranium present in U-enriched minerals as...

Late glacial to deglacial sedimentary

Late glacial to deglacial sedimentary Introduction  One of the peculiar interests of paleoclimatic reconstructions in the high southern latitudes involves the understanding of ice dynamic and ice-sheet behaviour mostly sensitive to temperatures and precipitations variations (Denton and Karlen, 1973; Aniya...

Antecedent hydroclimate conditions and statistical analysis of summer low tlow

Impact of peak SWE on low flow during summer To explore in more details the memory effect of snowpack conditions and how long water from snowmelt contributes and affects low tlow in summer. on summer low tlows, the peak SWE...

Dynamique naturelle et processus de paludification

SAMPLING DESIGN For this study, we used a part of the forest inventory database of the ministère des Ressources naturelles du Québec that covers two administrative regions (Abitibi-Témiscamingue and Nord du Québec). The sampling units of the forest inventory database...
