Black liquor is a major by-product of pulp mills; it is one of the most important renewable energy resources, which can be used as a material to produce electrical power, hydrogen, methanol and dimethyl ether by the black liquor gasification technology. In this paper, experiments were carried...

of a higher depreciation rate, which makes inventory riskier than fixed capital. In support of this result, our empirical work documents that risk premia, rather than real interest rates, are negatively related to future inventory growth. This relation is highly significant and robust to a...

This paper discusses linear regression of strongly correlated data that arises, for example, in magnetohydrodynamic equilibrium reconstructions. We have proved that, generically, the covariance matrix of the estimated regression parameters for fixed sample size goes to zero as the correlations...
