We propose land use dynamics models corresponding to parcels located on the edge of the forest corridor, Madagascar. We use semi-Markov chain to infer the land-use dynamics. In addition to the empirical and maximum likelihood methods, we estimate the semi-Markov kernel by a Bayesian approach. In the latter case, we use Jeffreys’ non-informative prior and we approximate the posterior distributio...

An inscription on the supporting wall of the inverted siphon of the aqueduct of the ancient Roman city of Patara, SW Turkey, explains how the wall collapsed during an earthquake and was subsequently restored. Carbonate deposits formed inside the aqueduct channel show cyclic stable isotope changes representing 17 years of deposition. This sequence, together with the text of the inscription, allo...

In the Spring 1987 issue of AUSS I examined the important Pro toSinai tic inscription discovered in 1960 by Georg Gers ter. This inscription is located a considerable distance west of the other Proto-Sinaitic inscriptions which cluster around the mines at Serabit el-Khadem.2 Both by its location and by its contents it appears quite distinct from the usual mining inscriptions or dedications writ...

Face aux nombreux défis sociétaux à relever (environnement, sécurité alimentaire, santé), différentes formes d’agriculture sont envisagées. Agriculture biologique, agriculture de conservation des sols et maintenant régénératrice trois récits fondateurs se référant l’agroécologie. Toutefois, l’agriculture régénératrice, nouvelle arrivée en France, reste ambiguë. Nous proposons un cadre d’analyse...

Colloidal suspensions are used to generate polymers or particles from which ceramic materials can be made by the sol-gel process. The precursors for preparation of a colloidal suspension consist of a metal element surrounded by various ligands (attached groups not including another metal). For example, common precursors for sol-gel synthesis of aluminum oxide include inorganic salts such as Al(...
