Introduction

Ensuring good quality air is essential for the protection of public health. Governments worldwide have adopted a range of increasingly demanding measures to curb air pollution with a particular focus on the emissions from motor vehicles. An important part of this strategy has been the development of the three-way catalytic converter to remove exhaust pollutants such as carbon monoxide, unburnt hydrocarbons and nitrogen oxides. This unit takes an in-depth look at the construction of this conve

1.4.10 Unfinished business

When people die suddenly we can never be sure that they have done and said what they want and are able to do. Meg’s long term-illness gave her a lot of time for reflection and preparation, so that while her death was sudden and she was unable to see her younger son, she also had the opportunity for conversations with people about her death. However, there may have been last-minute wishes that Meg was unable to express.

Li’s sudden stroke may have left her with things unsaid, but her
