• Sommario/riassunto: Tribology is a discipline concerned with contacting surfaces. This book shows how surface analytical techniques can be used together with the knowledge of basic principles of tribology to help understand failure processes. For instance, Chapter 8 shows how precision ball bearings and their critical lubrication requirements require knowledge of lubricant behavior of very thin films and surface reaction (boundary lubrication) for reliable performance. Thus if a bearing material is altered, it may be necessary to determine its effect on surface chemistry of lubricants. Surface analysis, including wear scar analysis, can be factored into test programs as a supplemental component or as an integral part of the set up.

• Sommario/riassunto: 'There is a place in the hippocampus the size of an almond called the amygdale in which is stored our emotional memory. Anything in our history that is a stimulus to our emotions resides there... The kernel of Catherine is there for the picking - I am searching for the correct tool like at Christmas when the nutcrackers have been misplaced. A hammer will shatter it.' Catherine is in a post-traumatic state and Simon, an eminent psychiatrist, is employed to help her recover her memory in time to give evidence in the trial of Joshua James - a young man accused of raping her. As the
