In order to elucidate interactions between climate change and biogeochemical processes and to provide a tool for comprehensive analysis of sensitivity, uncertainty, and proposed climate change mitigation policies, we have developed a zonally averaged two-dimensional model including coupled biogeochemical and climate sub-models, as a part of an Integrated Global System Model. When driven with ca...

We introduce and investigate a chemical model based on perturbative corrections to the product of singlet-type strongly orthogonal geminals wave function. Two specific points are addressed (i) Overall chemical accuracy of such a model with perturbative corrections at a leading order; (ii) Quality of strong orthogonality approximation of geminals in diverse chemical systems. We use the Epstein-N...

reliability wiener number is a modification of the original wiener number in which probabilities are assigned to edges yielding a natural model in which there are some (or all) bonds in the molecule that are not static. various probabilities naturally allow modelling different types of chemical bonds because chemical bonds are of different types and it is well-known that under certain condition...

We present version 3.0 of the atmospheric chemistry box model CAABA/MECCA. In addition to a complete update of the rate coefficients to the most recent recommendations, a number of new features have been added: chemistry in multiple aerosol size bins; automatic multiple simulations reaching steady-state conditions; MonteCarlo simulations with randomly varied rate coefficients within their exper...

804 Journal of Chemical Education • Vol. 83 No. 5 May 2006 • www.JCE.DivCHED.org It is generally accepted that laboratory work is an integral part of an undergraduate education in chemistry. Many recent attempts to reinvigorate the lab course, especially at the general chemistry level, have the general aim of promoting a more active approach by the students. There is much interest in changing t...
