SELENIUM IN HIGHER PLANTS.

Annual Review of Plant Physiology and Plant Molecular Biology, 2003
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-

Effects of volatilization on carbon and hydrogen isotope ratios of MTBE.

Environmental Science and Technology, 2009
Contaminant attenuation studies utilizing CSIA (compound-specific isotope analysis) routinely assume that isotope effects (IEs) result only from degradation.

Asymmetric Volatility and Volatility Spillovers

2016
Why indeed is volatility asymmetrical? Wholly apart from their epochal methodological contributions, providing an answer to this question may be the greatest theoretical advance traceable to time series models. This chapter will explore three distinct accounts of asymmetrical volatility.

Volatility of Prices and Volatility of Dividends

1998
The theoretical model which we present in this chapter is an attempt to develop a framework of analysis sufficiently general to study the volatility of stock prices when markets are efficient but with no a priori specification on the distribution of the relevant stochastic processes. To this aim, we shift the attention from dividends to earnings and we
