Our principal objectives were to examine the application of a time-series of advanced very high-resolution radiometer (AVHRR) data to contrast the inundation regimes of a range of large, climatically sensitive playas in the Zone of Chotts regions of southern Tunisia and northeastern Algeria. In doing so, we aimed to: (i) refine methods for monitoring monthly changes in lake areas and seasonal w...

We investigated the source characteristics of large earthquakes which occurred in the Michoacan, Mexico, seismic gap during the period from 1981 to 1986 in relation to historical seismicity in the region. The rupture pattern of the Michoacan gap during this period can be characterized by a sequential failure of five distinct asperities. Before 1981, the Michoacan gap had not experienced a large...

Introduction: A variety of salts have been identified on Mars by by spectrometers on board orbiters and robotic landers, including sulfates, carbonates and chlorides [1, 2, 3]. All sulfates identified on Mars to date appear hydrated or hydroxylated. This indicates that sulfates on Mars originate from aqueous solution. Terrestrial analog studies can play an important role in helping to constrain...

Abstract Salicornia europaea L. is a common halophytic plant species distributed in many saline soils and habitats, including margins of many wetlands. Salicornia europaea grows around Mighan Wetland, a natural desert ecosystem in central Iran with fluctuating water levels due to constant heat and severe wind throughout the year. Although, aspects of biology and ecology of halophytes growi...

The first two specimens of Regalecus glesne Ascanius, 1788, collected in the Argentine Sea, at Playa Unión beach, 43o 18' S, 65o 02' W are reported. Body measurements, meristic characters and morphological data are given. The most important differences with two other regalecid species, R. russelii Cuvier and R. kinoi Castro-Aguirre et al. 1991, from the Pacific coasts of Mexico, are considered....

This is the written version of a lecture given at the “VI Mexican School of Gravitation and Mathematical Physics” (Nov 21-27, 2004, Playa del Carmen, México), introducing the basics of Loop Quantum Geometry. The purpose of the written contribution is to provide a Primer version, that is, a first entry into Loop Quantum Gravity and to present at the same time a friendly guide to the existing ped...
