This e-book is designed for viewing via a wide variety of html browsers. Although text can be read with 640x480 screen resolution, to see diagrams and text together, 800x600 screen resolution is necessary. To minimise vertical scrolling fullscreen viewing is recommended. You can change the size of text by selecting the appropriate option from your browser menu. Diagram animation sequences are repeated every 30 seconds. Depending on your browser, you may be able to restart an animation sequence by clicking on Refresh or Reload, and halt a sequence by clicking on Stop. To navigate around the book, click on the top or bottom bar or arrow symbols, or click on red underlined text. The next page contains an index of main level contents. A full alphabetic index which includes subordinate pages can be accessed by clicking on the left arrow at the top of this page. |
