Two sets of blading, designed for 120 per cent reaction, and for flow coefficients of 0" 667 and 1.0 respectively, have been tested in the N.G.T.E. low-speed compressor No. 106. The performances were compared with those of corresponding sets of 50-percent reaction blading and with predictions based on simple theoretical methods. The high-reaction bladings both gave efficiencies which were lower...

Background This article looks at the long-term, structural determinants of environmental and public health performance in the world system.   Methods In multiple standard ordinary least squares (OLS) regression models, we tested the effects of 26 standard predictor variables, including the ‘four freedoms’ of goods, capital, labour and services, on the following indicators of sustainable develop...

external fluted feed rolls are commonly used in grain drills. the fluted feed roll meters a volume of seeds and does not singulate the seeds as do the precision planters; therefore, there will be inherent variation in the number of seeds delivered per unit of time. this research was conducted to investigate the effect of seed meter drive shaft and ground speeds and outlet positions in a grain d...

determining landslide size could be a difficult and expensive task. in this research, size parameters of 142 landslides recognized in tajan river basin, northern iran, have been assessed. the dataset was prepared through the extensive field surveys and using the satellite imagery available via google earth. dependence between landslides area (a-m2), volume (v-m3), and depth (d-m) was appointed ...

environmental impact assessment (ela) today is a planning tool that is used for the prediction of environmental impacts. there are several methods to assess environmental impacts in the world and iran as well. among them system analysis approach using degradation model (makhdoum, 1996) has shown it's effectiveness. degradation model is used at different levels including the basin , catchme...
