Current scientific knowledge of Tertiary fossils from south of the Ailao Shan-Red River shear zone is extremely poor, in sharp contrast with the situation nowadays, as the area of Laos and Vietnam is regarded as a global hotspot of biodiversity. In this context, the few localities that yielded fossil assemblages are of first importance for the understanding of Cenozoic palaeobiogeography and...

For many crops, wild relatives constitute an extraordinary resource for cultivar improvement [1, 2] and also help to better understand the history of their domestication [3]. However, the wild ancestor species of several perennial crops have not yet been identified. Perennial crops generally present a weak domestication syndrome allowing cultivated individuals to establish feral populations...

Comparative study of the Pleistocene Cakmak quarry (Denizli Basin, Turkey) and modern Mammoth Hot Springs deposits (Yellowstone National Park, USA)

Boever, Eva De ; Foubert, Anneleen ; Lopez, Benjamin ; Swennen, Rudy ; Jaworowski, Cheryl ; Özkul, Mehmet ; Virgone, Aurélien

This study compares and contrasts the travertine depositional facies of two of the largest sites of travertine formation, located in very different geological contexts, i.e. the modern Mammoth Hot Spring (MHS) system in the active volcanic complex of Yellowstone National Park (USA) and the Pleistocene Cakmak quarry, a well-exposed example of the Ballık travertines in the extensional Denizli...

A twin crystal-spectrometer assembly, operated in the focusing compensated asymmetric Laue geometry has been developed for accurate spectroscopy of fast highly charged heavy ions in the hard-X-ray region. Coupled to the focusing crystal optics is a specially developed two-dimensional position-sensitive X-ray detector which is necessary for retaining spectral resolution also for fast moving...

Accès et recours aux soins de santé dans la sous-préfecture de Ouessè (Bénin)

Richard, Jean-Luc ; Chiffelle, Frédéric (Dir.)

Thèse de doctorat : Université de Neuchâtel : 2001 ; 1604.

Cette thèse de géographie de la santé, plus spécifiquement de géographie des services et soins de santé, décrit une région rurale du Bénin central - la sous-préfecture de Ouessè - à travers les comportements de recherche de soins de santé de ses habitants. Au moyen du concept central d'accès, dont plusieurs dimensions sont explicitées et analysées, nous avons confronté les...
