wind regime data from the jask meteorological station from a 20-year statistical period (1985-2005) was analyzedusing the fryberger method to investigate sand drift potential (dp) in this area. the resultant drift potential anddirectional variability of wind were calculated and illustrated. average annual sand dp was estimated to be 460vector units (vu), and the sand flux is 51 m3/m.year. there...

We analyze the migration characteristics of a droplet in an oscillatory flow field in a parallel plate microconfinement. Using phase field formalism, we capture the dynamical evolution of the droplet over a wide range of the frequency of the imposed oscillation in the flow field, drop size relative to the channel gap, and the capillary number. The latter two factors imply the contribution of dr...

Animal movement patterns in space and time are a central aspect of animal ecology. Remotely-sensed environmental indices can play a key role in understanding movement patterns by providing contiguous, relatively fine-scale data that link animal movements to their environment. Still, implementation of newly available remotely-sensed data is often delayed in studies of animal movement, calling fo...

AD’s behavioral complexity and generalized end-stage pathology sheltered it from twentieth century cortical localizationism. But fundamental principles of brain organization cannot be avoided forever. Cummings [3] has developed a comprehensive case for recognizing the relevance of cortical localization to a twenty-first century understanding of AD. Our work supports this proposal by suggesting ...

Dispersal capabilities determine and maintain local gene flow, and this has implications for population persistence and/or recolonization following environmental perturbations (natural or anthropogenic), disease outbreaks, or other demographic collapses. To predict recolonization and understand dispersal capacity in a stream-breeding frog, we examined individual movement patterns and gene flow ...

The aim of this study was to compare the effect of neuro-development treatment (NDT) technique and NDT plus botulinum toxin type A (BTX-A) injection on the reduction of spasticity and improvement of the quality of movement patterns of lower limb in hemiplegic patients. For this purpose, 15 hemiplegic (8 female and 7 male cases) with an age range of 27-70 years participated in this study. The pa...

the determination of temporal and spatial salinity in tidal rivers is significant in supplying water for agriculture purposes, particularly where there is no controller dam at the downstream. in this research, the coherens model was applied to study the hydraulics of water flow, salinity distribution and transmission at the bahmanshir river. coherens is a 3d multi-purpose hydrodynamic model whi...

Predicting fish responses to modified flow regimes is becoming central to fisheries management. In this study we present an agent-based model (ABM) to predict the growth and distribution of young-of-the-year (YOY) and one-year-old (1+) Atlantic salmon and brown trout in response to flow change during summer. A field study of a real population during both natural and low flow conditions provided...
