Il existe une certaine confusion entre les termes études, expérimentations, recherche fondamentale, recherche finalisée... Plus largement, la position de la recherche dans la société et plus particulièrement dans le milieu des espaces forestiers méditerranéens mériterait d'être mieux appréhendée. Dans cet article, Yves Birot nous apporte un éclaira...
Inter Press Service (IPS) is widely considered to be distinctly different from the conventional news agency. Research on this alternative news agency has mainly focused on the IPS news to underwrite this statement, but much less attention has been paid to the broader production context. Drawing on the findings of twenty-six semi-structured in-depth...

Except in the most hindered of cases, N,N'-diaryl N,N'-dimethyl ureas adopt a conformation with the two aryl rings disposed cis to one another. Variable temperature NMR studies reveal the rate at which the Ar-N bonds rotate as well as the conformational preference of ortho disubstituted ureas in which more than one cis orientation is possible. In g...
In this correspondence, we present new construction methods for quaternary low-correlation zone (LCZ) sequence sets from a binary sequence with good autocorrelation. We show that the sets obtained by our methods are optimal or nearly optimal with respect to the Tang-Fan-Matsufuji bound and that our construction methods are more flexible than any ot...
Public participation is increasingly considered as a plain part of the assessment and the management of a contaminated site. It is also perceived as a difficult and sometimes risky challenge. In Europe, to our knowledge, beside académie virtual experiments on "test groups", feedback and recommendations on the subject are scarce and dispersed. Follo...
We develop a smart-skin phased array antenna (PAA) with a scanning beam and cover the design, fabrication and testing of the smart-skin antenna structure, the phase shifter and electronic beam scanning. The smart skin is an organic honeycomb sandwich structure in which microstrip antennas are embedded that radiate a radio-frequency (RF) signal. The...

Au Sahel, des villes nées à l'époque coloniale connaissent un renouveau actuel par le passage de migrants internationaux. Ces circulations à longue distance dynamisent l'espace local. La ville de Kayes, dans l'ouest du Mali, est concernée par les flux interafricains de voyageurs. Elle doit son attrait à sa position dans les réseaux de transport oue...
