The notion of choice has been characterised as one of the regulating agents of intrinsicmotivation. A study being carried out at the Université H. Poincaré is investigating the effect ofchoice on cognitive and affective engagement during listening tasks. The study compares twogroups of English language learners specialising in other disciplines. The aim of the study is toattempt...

The purpose of applying the high-energy γ-ionizing radiation with doses up to 100 kGy was to enable controllable change of mechanical properties of high impact polystyrene (PS-HI) and, at the same time, to investigate the possibility of using reprocessed irradiated polymeric material. Dielectric relaxation of radiation modifi ed high impact polystyrene (PS-HI) has been investigated below the po...

Nitrogen supplied by N2 fixation to soybean [Glycine max (L.) Merr.] may not be sufficient to maximize yield. Field studies were conducted in 2002, 2003, and 2004 on Sharkey clay soil (very-fine, smectitic, thermic Chromic Epiaquert) at Stoneville, MS (33 269 N lat). The objective was to determine the effect of high rates of N applied as a replacement for N2 fixation in nonirrigated and irrigat...

nature) can usually be explained by either increased pleural fluid formation or decreased pleural fluid absorption, or both. Pleural effusions caused by an increase in pleural fluid formation can be further subdivided into elevation in hydrostatic pressure (e.g., congestive heart failure), decreased colloid osmotic pressure (e.g., cirrhosis, nephrotic syndrome), increased capillary permeability...

A functional characterization of the cerebellum centers on the hypothesis that this structure is essential for the representation of temporal relationships in the subsecond range. This hypothesis is supported by evidence involving a wide range of methods, including lesion studies, neuroimaging, and, to a limited extent, stimulation studies with transcranial magnetic stimulation. The extent of t...

The teaching of Languages for Specific Purposes (LSP) in the second half of the twentieth centuryhas been greatly influenced both by the communicative approach and by developments inresearch in discourse analysis, particularly with reference to genre. The integration of researchin corpus linguistics in the language-learning environment has been a more recent phenomenon,with publ...

Introduction Hydrogeologic investigations are often hampered by insufficient information about the site-specific hydrostratigraphic features that control ground water flow and solute transport. Field and modeling studies in a wide variety of geologic settings have shown the importance of a detailed description of aquifer heterogeneity for applications ranging from prediction of contaminant tran...
