This book introduces aqueous geochemistry applied to geothermal systems. It is specifically designed for readers first entering into the world of geothermal energy from a variety of scientific and engineering backgrounds, and consequently is not intended to be the last word on geothermal chemistry. Instead it is intended to provide readers with sufficient background knowledge to permit them to subsequently understand more complex texts and scientific papers on geothermal energy. The book is structured into two parts. The first explains how geothermal fluids and their associated chemistry evolve, and shows how the chemistry of these fluids can be used to, deduce information about the resource. The second part concentrates on survey techniques explaining how these should be performed and the procedures which need to be adopted to ensure reliable sampling and analytical data are obtained. A geothermal system requires a heat source and a fluid which transfers the heat towards the surface. The fluid could be molten rock (magma) or water. This book concentrates on the chemistry of the water, or hydrothermal, systems. Consequently, magma-energy systems are not considered. Hot-dry rock (HDR) systems are similarly outside the scope of this text, principally because they contain no indigenous fluid for study. Both magma-energy and HDR systems have potential as energy sources but await technological developments before they can be exploited commercially. Geothermal systems based on water, however, are proven energy resources which have been successfully developed throughout the world.

This book offers a welcome expansion on key concepts, terms, and issues in causality. It brings much needed clarity to psychological injury assessments and the legal contexts that employ them.

Focusing on PTSD, traumatic brain injury, and chronic pain (and grounding readers in salient U.S. and Canadian case law), the book sets out a multifactorial causality framework to facilitate admissibility of psychological evidence in court.

PTSD, pain syndromes, traumatic brain injury: these three areas are common features of personal injury cases, often forming the cornerstone of expert testimony. Yet their complex interplay in an individual can make evaluation and explaining the results in court extremely difficult.

Psychological Knowledge in Court focuses on this triad separately and in combination, creating a unique guide to forensic evaluations that fulfills both legal and clinical standards. Its meticulous review of the literature identifies and provides clear guidelines for addressing core issues in causality, chronicity, and assessment, such as:

- Are there any definable risk factors for PTSD?

- How prevalent is PTSD after trauma?

- How do patients emotions relate to their pain experience?

- Are current pain assessment methods accurate enough?

- What is the role of pre-existing vulnerabilities in traumatic brain injury?

- What exactly is "mild" TBI?

This sequel to the authors' Psychological Knowledge in Court offers a welcome expansion on key concepts, terms, and issues in causality, bringing much needed clarity to psychological injury assessments and the legal contexts that employ them. This book clearly explains what lawyers and clinicians need to understand about each other's work. Forensic practitioners and attorneys will turn to Causality of Psychological Injury as their professional paths increasingly cross in seeking comprehensive and state of the art information.
