Modern trends in iron metallurgy. Global carbon emissions from iron production. New solution for iron and steelmaking in a way reduce the CO2 emission to the level, where this might be needed in the post Kyoto period. New blast furnace technology, which operate with very low CO2 emissions based on drastically reduced consumption of carbon containing input materials. Injection of reducing gases ...

We consider a one-dimensional random walk beginning at the origin and moving ± cn at time n. If ∑ cn < ∞ then with probability one the random walk has a final location. We describe the distribution of the final location and find the cumulants and the moments in terms of the power sums of the step sizes. Some interesting definite integrals involving infinite products of trigonometric functions c...
