The Pennsylvanian flora from the intramontane Erillcastell Basin in eastern Pyrenees (Catalonia, Spain) is described a palaeoenvironmental context based on combined study of sedimentology, plant taphonomy and paleoecology. This basin differs other Pyrenean basins this age comprising wide array fluvial channel floodplain-related facies, with limited development peat mire facies. Both late Moscov...

Cet article met en lumière les processus cognitifs qui sous-tendent la démarche diagnostique ainsi que sources d’erreurs de diagnostic et montre comment chacun chacune peut, ici maitenant, atteindre l’excellence diagnostique.

A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.

An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...

Pollen analysis and AMS radiocarbon dating of a short sediment core from a mire in Veisar (Mazandaran province, N Iran) reveals the late-Holocene vegetation history of the area. High pollen values suggest that Caucasian alder (Alnus subcordata) has been present in the vicinity of the mire throughout the record. Wingnut (Pterocarya fraxinifolia), which was previously abundantly present, shows a ...

The data on the coordination and structure of iron(II) and iron(III) anthranilates in the solid state and in aqueous medium are presented and discussed, as studied using Mössbauer (for solid products and frozen solutions) and FTIR spectroscopy (for solid samples). Whereas, in slightly acidic nitrate solutions under aerobic conditions ferric ions can still be gradually reduced by anthranilic (o-...
