Mathematical Modelling of Environmental and Ecological Systems

Part I - Air Pollution. Some aspects of mathematical modelling of atmospheric transport and chemistry (L.K. Peters). Attenuation of air pollution by green belt (R.K. Kapoor, V.K. Gupta). Dispersion of a reactive air pollutant in a two layered environment (J.B. Shukla, R.S. Chauhan). Dispersion from a time dependent point source: Application to methyl isocynate leakage in Bhopal, India (R.S. Chauhan, J.B. Shukla and T.G. Hallam). Part II - Water Pollution. Taking advantage of topography in the siting of discharges in rivers (R. Smith). Analytical solution of 3-D unsteady state diffusion equation for a pollutant from a point source discharge in offshore region (V.P. Shukla). Part III - Population Ecology. Modelling survival in chemically stressed populations (T.G. Hallam). On the general structure of epidemic models (E. Beretta, V. Capasso). Equilibria and oscillations in age-structured population growth models (J.M. Cushing). Part IV - Community Ecology. Young predation and time delays (M. Saleem, V.S. Siddiqui and V. Gupta). Uniform persistence and global stability in models involving mutualism. I Predator-prey-mutualistic systems (H.I. Freedman, B. Rai). Part V - Resource Management. Dynamic interactions between economic, ecological and demographic variables (A. Cigno). Economic growth models: Effects of logistic population and technology (A. Shukla). A dynamic predator-prey model for the utilization of fishery resources: A case of trawling in Lake Kasumigaura (Y. Kitabatake).
