Ethnomethodology is an established method of research in technology related fields. In work settings, ethnomethodology has helped researchers to deepen their understanding of how collaborative activities unfold in a social context. While much collaboration is now carried out online, through distributed teams for example, ethnomethodology, as a method of analysis, has not received considerable i...

In this study was examined the factors affecting the unwillingness to adopt pressurized irrigation methods among farmers' groups (with different levels of drought) in Ardabil province (Iran). Mixed method (Qualitative – Quantitative paradigm) was used for doing this research. First, by drought zoning of Ardabil province (by SPI method and GIS), three regions included the mild, moderate and seve...

Abstract Oxy-coal combustion with pressurized fluidized beds has recently emerged as a promising carbon capture and storage (CCS) technology for coal-fired power plants. Although large number of energy efficiency analyses have shown that an increase in pressure can further the net plant efficiency, there are few experimental studies oxy-coal conducted on bed combustors/boilers continuous coal f...

Numerical simulations have been carried out for spontaneous ignition of pressurized hydrogen release directly into air. Results showed a possible mechanism for spontaneous ignition due to molecular diffusion. To accurately calculate the molecular transport of species, momentum and energy in a multi-component gaseous mixture, a mixture-averaged multi-component approach was employed in which ther...

Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...
