A portion of Arizona's San Pedro River is managed as a National Riparian Conservation Area but is potentially affected by ground-water withdrawals beyond the conservation area borders. We applied an assessment model to the Conservation Area as a basis for monitoring long-term changes in riparian ecosystem condition resulting from changes in river water availability, and collected multi-year dat...

The aim of this study was to assess the potential impact of Trout farm effluents on water quality of Zaringol stream based on NSFWQI and WQI indexes. Some physicochemical water quality parameters were measured from 14 point during December 2009 to September 2010 seasonality. The average value of NSFWQI is 53.21 and it shows spatial and temporal variation. The maximum value or best water quality...

Research within the Cardiff Marine Energy Research Group (CMERG) has considered the integrated mathematical modelling of Tidal Stream Turbines (TST). The modelling studies are briefly reviewed. This paper concentrates on the experimental validation testing of small TST models in a water flume facility. The dataset of results, and in particular the measured axial thrust signals are analysed via ...

Parameatal urethral cysts are a rare benign condition usually seen in males. They are usually asymptomatic but may producesymptoms like difficulty in micturition, pain during intercourse, urinary retention and distortion of the urinary stream. We reporta case of parameatal urethral cyst in a 17 year old male presenting as a spherical clear fluid filled cystic lesion measuring about 0.8cm in dia...

The sequential organization of sound over time can interact with the concurrent organization of sounds across frequency. Previous studies using simple acoustic stimuli have suggested that sequential streaming cues can retroactively affect the perceptual organization of sounds that have already occurred. It is unknown whether such effects generalize to the perception of speech sounds. Listeners'...

this study sougth to the effect of occ pulp fractionation on produced paper strength properties improvement. using a pressure screen, occ pulp was devided to tow distinct fractions of accept ratio (short fibers) and reject ratio (long fibers) in accordance with optimum condition of fractionation based on the previous studies. in the next stage, long fiber stream was refined and recombined with ...

Scientists have long assumed that the physical structure and condition of stream and river channels have pervasive effects on biological communities and processes, but specific tests are few. To investigate the influence of the stream-reach geomorphic state on in-stream habitat and aquatic macroinvertebrate communities, we compared measures of habitat conditions and macroinvertebrate community ...
