4.3 Thermally activated processes

Thermally activated processes are those that get going not because of average effects, but because the fraction of particles in the tail of the distribution increases with temperature. This is a basic property of the thermal distribution we have been discussing. For instance, what would take 30 000 years at room temperature may happen in under one second at 1000 K if it depends on how many particles have an energy in excess of 1 eV.

The next step in the study of energy distribu

3.6.3 Balancing emotional commitment with awareness and understanding

People's first donation is often prompted by an instinctive and emotional response to a direct appeal. Very rarely is it an informed or carefully calculated decision. Building on that initial response requires you to balance a recognition of your donors’ emotional investment with a need to develop their understanding and awareness of your cause and concerns – the head and heart messages central to your case statement.

4 Unit summary

Sound recording really took off once the public's demand for recorded music had been acknowledged. The choice of technology, cylinder or disc, was determined more by the selection of the artist and material than the quality of the sound. Development of disc technology was slow due to the lack of better alternatives, remaining substantially unchanged for over fifty years. The development of radio broadcasting caused a slump in the record industry but eventually it not only provided improvement

Grammar Representations to Facilitate Style Innovation - An Example From Mobile Phone Design
Previous research in generative design has suggested that shape grammar transformations could be used for developing new design styles by the systematic modification of grammars that encode existing styles. Our research explores how such grammar transformations can be facilitated to be responsive to changes in design style requirements. For this it is important to consider the structure and organization of rules, as well as the description of the styles of designs generated by a grammar. Using a

1.2.7 In praise of cheap offshore labour?

Claims over the benefits of globalisation and the exploitation of cheap offshore labour generate strong feelings and, not surprisingly, divide opinion between those who favour the global marketplace and its detractors. The issue turns on whether the constant search for ever-cheaper manufacturing and service locations is seen as a good or a bad thing. It may appear odd, at first, to suggest that exploiting the poor of another country can, on any measure, be regarded as a good thing, but

2.2.2 Hollow tubing surfaces

In their doughnut-shaped representation, toruses can be thought of as being hollow tubes. Many other surfaces in space can also be drawn as if they were made of hollow tubing. Figure 15 shows two such examples.

4.1.1 Disability discrimination legislation

This activity uses the UK Disability Discrimination Act (DDA) Part 4 as the basis for discussing the concept of making reasonable adjustments. The DDA may not apply to you directly, but many countries have similar legislation. We feel the underlying principles of such legislation reflect the moral standpoint or the right thing to do, regardless of whether or not legislation exists.

5.1 Introduction

We have seen some of the difficulties that Mrs Biggs has faced when formulating a sufficiently general and sufficiently specific rule to deal with the conduct of the visitors to her garden. In Part D we take things a step further by looking at some of the difficulties which may arise when it comes to interpreting rules such as the one developed (with your help) by Mrs Biggs. In particular, we will be exploring the way in which our understanding of the language used in rules affects our interp

Brexit and the EU Global Strategy [Audio]
Speaker(s): Nathalie Tocci | Undoubtedly Brexit has dealt a major blow, both to the UK's role in the world and that of the EU. As one if not the Member State with the most global outlook, the damage done both in terms of material capacities and reputation cannot be underestimated. At the same time some argue that the UK's exit from the EU would facilitate integration in the security and defence field. What are the prospects for the implementation of the EU Global Strategy following the UK refere
