Ultimate origin of “ore solutions”: Ocean water?

Ore Subresultants in Solutions

The subresultants play a fundamental role in elimination theory and computer algebra. Recently they have been extended to Ore polynomials. They are de ̄ned by an expression in the coe±cients of Ore polynomials. In this paper, we provide another expression for them. This expression is written in terms of the \solutions" of Ore polynomials (in \generic" case). It is a generalization of our previou...

Whence God? The origin of ultimate concern

Several recent works have addressed the issue of the origin of religion. Some have linked this occurrence to evolutionary mechanisms, others to sociological processes, and still others to psychological functions. Each position has interest and sheds a different light on a necessarily complex process. The paper examines several of these theories and offers a synthetic perspective which integrate...

Risk Averse Approaches in Open-pit Production Planning under Ore Grade Uncertainty: a Ultimate Pit Study

During early phases of open-pit mining production planning many parameters are uncertain, and since the mining operation is performed only once, any evaluations based only on on average outcomes neglects the very real chance of obtaining an outcome that is below average. Taking into account also that operation costs are considerable and the mining horizon usually extends over several decades it...

Simulating Ocean Water

Deep-ocean origin of the freshwater eels

Of more than 800 species of eels of the order Anguilliformes, only freshwater eels (genus Anguilla with 16 species plus three subspecies) spend most of their lives in freshwater during their catadromous life cycle. Nevertheless, because their spawning areas are located offshore in the open ocean, they migrate back to their specific breeding places in the ocean, often located thousands of kilome...
