Nuclear tunneling and other nuclear quantum effects have been shown to play a significant role in molecules as large as enzymes even at physiological temperatures. I discuss how these quantum phenomena can be accounted for rigorously using Feynman path int ...
Magnetohydrodynamic (MHD) equilibrium states with a three-dimensional helical core that display the characteristics of a saturated ideal internal kink mode are computed to model snake structures that have been observed in the JET tokamak [A.~Weller et al. ...
The European railway sector has undergone major transformations over the past two decades. Domestic reforms have been buttressed by European directives aimed at creating a single European railway market. In this new environment roles have been significantl ...
The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated ...
The Bases of Chemical Thermodynamics: Volume 2 In this volume (volume 2), the tools necessary to study and understand systems in which chemical reactions can take place are developed. The variables of reaction are the keys to this understanding. Criteria f ...
The Bases of Chemical Thermodynamics: Volume 1 In this volume (volume 1), the fundamental aspects of thermodynamics are presented. The first and second laws of thermodynamics are illustrated. The need to define thermodynamic temperature and the nature of e ...
Environmental Context. The chemical speciation of trace metals greatly influences their biological effects. Nonetheless, no clear consensus currently exists as to when metal complexes are bioavailable, especially for field conditions. Recently, the USA EPA ...
This paper proposes a dynamic-game theoretic model for the international negotiations that should take place to agree on a global mitigation scheme when the real extent of climate change due to anthropogenic emissions is known. The model assumes a non-coop ...

Trace metal bioavailability is often evaluated on the basis of steady-state models such as the free ion activity model (FIAM) and the biotic ligand model (BLM). Some of the assumptions underlying these models were verified by examining Pb and Zn uptake by ...
Two biomass gasification concepts, i.e. indirectly heated, steam blown fluidised bed gasification and directly heated, air blown fixed bed gasification are modelled with adjusted equilibrium equations, their energy requirements are integrated and an exergy ...
