Fertility, Living Arrangements, Care and Mobility
There are four main interconnecting themes around which the contributions in this book are based. This introductory chapter aims to establish the broad context for the chapters that follow by discussing each of the themes. It does so by setting these themes within the overarching demographic challenge of the twenty-first century – demographic ageing. Each chapter is introduced in the context of the specific theme to which it primarily relates and there is a summary of the data sets used by the contributors to illustrate the wide range of cross-sectional and longitudinal data analysed

Surface characterization of chemically modified wool
The surface topography of wool fiber, and in particular the scale height and surface roughness, has been characterized using three-dimensional scanning electron microscopy (3D-SEM). The analysis methodology allows the scale height and surface roughness to be accurately and quickly measured, and may provide detailed information about the fiber topography, any associated damage and possible surface coatings. The treatment of wool fiber with potassium permanganate in salt solution was assessed using 3D-SEM and the progressive reduction in the scale height and cuticle smoothing demonstrated. While this effect was relatively obvious and uniform, the effect of a proteolytic enzymatic treatment on the fiber surface was less uniform. The associated effect of the enzymatic modification on the felting shrinkage, fabric strength, and handle was also determined
