An analytical solution of the partial differential equation describing the enthalpy balance of the cooling fluid in a batch exothermic reactor has been developed for a constant flow. Thanks to an analytical integration on position, the simulation of the process can be performed with one...

Problems such as conduction of nerve impulses, behavior of the immune system or of effects of medication, and many others, when modelled by differential equations, are amenable to solution by a mathematical procedure called the decomposition method. This method is efficient and accurate; it makes...

A conference report on UNESCO and Fundacion Bariloche sponsored conference with policy-oriented scientists from Africa, Europe, Latin America, and the United States of December 1976. The focus was on global modelling, its formalization and reliability. The applications were to problems of...

This paper presents and discusses schemes of prevention measures in public health. A mathematical model is purposely designed to outline various features related to cost issues and a numerical application to Italian cancer data is used to show the flexibility and utilization of the model.
