The equation of state of tantalum (Ta) has been investigated to 100 GPa and 3,000 K using the first-principles molecular dynamics method. A large volume dependence of the thermal pressure of Ta was revealed from the analysis of our data. A significant temperature dependence of the calculated effective Grüneisen parameters was confirmed at high pressures. This indicates that the conventional app...

Threshold Accepting (TA) is a powerful optimization heuristic. Using several examples from economics, econometrics and statistics, the issues related to implementations of TA are discussed and demonstrated. A problem specific implementation involves the definition of a local structure on the search space, the analysis of the objective function and of constraints, if relevant, and the generation...

While the social economy originated in Europe (Desroche, 1983; Gueslin, 1997; Vienney, 1994), by the nineteenth century it emerged in North America as well, particularly in Canada and Quebec with its ties to the United Kingdom and France as well as other European countries, especially Germany and Belgium. Today, it is interesting to explore the renewal of the social economy in Europe and in Can...

in recent years, the teaching of grammar and the importance attached to it has become a bone of contention among language teaching professionals. the emergence of the communicative approach (ca) in second or foreign language teaching has been one of the most important factors leading to this controversy. since the advent of ca in the second half of the 1970's grammar which had always occup...

The marine CaCO3 cycle is an important component of the oceanic carbon system and directly affects the cycling of natural and the uptake of anthropogenic carbon. In numerical models of the marine carbon cycle, the CaCO3 cycle component is often evaluated against the observed distribution of alkalinity. Alkalinity varies in response to the formation and remineralization of CaCO3 and organic matt...
