This is the fifth and final unit in the MSXR209 series on mathematical modelling. In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used.

This unit, the fifth in a series of five, builds on ideas developed and introduced in Modelling pollution in the Great Lakes

2.9 Summary

In this section, I started by emphasising the fact that the computer, which has become more or less omnipresent in modern society, is a tool like any other.

I went on to look at the special nature of that tool, establishing that its function is to capture, store, present, exchange and manipulate interesting aspects of the world.

I then introduced the idea of two contrasting realms: the analogue world we inhabit and the digital interior world of the computer. When we capture featur

The DPS protein compacts the eubacterial chromosome during stress

When an E. coli cell enters into stationary phase, transcription and cell division cease completely. In such cells, the normal chromatin components, such as those described above, are replaced by a negatively charged protein called DPS. The interaction between DPS and DNA appears to be a specialised bacterial adaptation to survive starvation. In normal conditions of growth, the DNA within the bacterial cell is distributed evenly throughout the entire cytoplasm. In stationary cells, how

People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance. Communication networks have become very important, and modern society depends on them for the smooth operation of economic and social activities. In this unit we regard a

And their activities raise the issue of status citizenship and the role of legal sanctions. The forms of commitment by firms and their monitoring by the organisations just outlined are voluntary on the part of companies. One of the problems with the emphasis on acts citizenship in the debates about GCC is that the question of status citizenship is largely
