Multi-regional input–output (MRIO) models are widely used to analyze the economic interdependencies between regions in context of global trade and environmental research. MRIO tables enable us teleconnect sectors different along supply chain track both direct indirect impacts production. Yet emerging economies—despite reshaping international patterns playing an increasingly important role world...

kashan aquifer is adjacent to salt lake. because of this adjacency, the saline water of the lake has moved to the aquifer. in this study groundwater quality of the aquifer was simulated using artificial neural network (ann) model. for this purpose, the dominant ion of water was first determined by piper diagram. results showed that the sodium chloride is the dominant ion of water and so it was ...

abstract aims: one of the consequences of taking ground water into surface is changing its chemical quality, specially increasing the concentration of dissolved salts. this research was performed in order to analyze growth possibility of heterotrophic bacteria in the membrane of active desalination plants in kashan city, iran. instrument & methods: this descriptive cross-sectional study was don...

We explain the raison d’être and basic ideas of input/output logic, sketching the central elements with pointers to other publications for detailed developments. The motivation comes from the logic of norms. Unconstrained input/output operations are straightforward to define, with relatively simple behaviour, but ignore the subtleties of contraryto-duty norms. To deal with these more sensitivel...

The memory plates can be used with con ventional 2-to-1 current -coincidence drive. This is particularly suitable for compact, lower power consuming, transistor driven, memories of relatively small capacity. A new method is proposed of driving memories particularly suitable for plates. The memory plates are driven by an end-on switch itself made of plates. The switch operates in a set-a-line an...
