The Effect of Immigration on Criminal Phenomena

Migration as a human phenomenon has some consequences and repercussions. One of these effects is crime commitment and inducing disturbance in land and national security in immigrants' residence country, in other word, international migration, especially illegal migration, have different penal-security effects. Finding reason that the permeability of borders and increasing illegal traffic, drug ...

Kinetics of chalcopyrite galvanic leaching using sulfate media at the low temperature in the GalvanoxTM process

In this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°C to 50°C. In the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. Effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...

Imposed currents in galvanic cells

We analyze the steady-state behavior of a general mathematical model for reversible galvanic cells, such as redox flow cells, reversible solid oxide fuel cells, and rechargeable batteries. We consider not only operation in the galvanic discharging mode, spontaneously generating a positive current against an external load, but also operation in two modes which require a net input of electrical e...
