An isolation system installed in a nuclear power plant (NPP) could increase seismic safety during events. On the other hand, more significant relative displacement may occur due to system. The risk be increased case of an interface piping that connects isolated and nonisolated structures. Therefore, it is necessary consider systems when evaluating isolated-NPPs. This study performed fragility a...

Emulsification of produced immiscible mixed liquid of oil and water is a problem frequently recognized in surface production facilities in oil fields. The formed emulsions are required to be demulsified to avoid the negative consequences on piping and processing equipment. Nowadays, chemical demulsification is a preferable method to avoid or retard emulsification during the process of oil treat...

piping sometimes is occurred due to seepage of water in hydraulic structures. the continuty of this phenomenon decreases the safety or caused the failure of a structure. in this work, experimental tests were carried out on statically compacted natural and randomly reinforced silt sandy soil samples. the randomly reinforced samples were prepared with different lengths and percentages of an artif...

Abstract The combination of meaning-bearing units (e.g., words ) into higher-order structures compound and phrases) is integral to human language. Despite this central role syntax in language, little known about its evolutionary progression. Comparative data using animal communication systems offer potential insights, but only a handful species have been identified combine meaningful calls toge...

The intensive development of gas transport and compressor manufacturing aimed at increasing the unit capacities pumping units, creating high-flow centrifugal compressors, productivity shops has led to appearance fundamentally new problems in diagnosis industrial pipelines. reasons for premature failure piping manifold stations can be associated with both high static voltage pipelines a level vi...
