Over the last two decades, advances in the design, miniaturization, and analytical capabilities of portable X-ray fluorescence (pXRF) instrumentation have led to its rapid and widespread adoption in a remarkably diverse range of applications in research and industrial fields. The impetus for this volume was that, as pXRF continues to grow into mainstream use, analysts should be increasingly empowered with the right information to safely and effectively employ pXRF as part of their analytical toolkit. This volume provides introductory and advanced-level users alike with readings on topics ranging from basic principles of pXRF and qualitative and quantitative approaches, through to machine lea...
Disasters in World History surveys the development of disaster studies as a discipline as well as presenting historical case studies and theories used by historians to understand disasters. Disasters, here defined as the complex interaction between natural hazards and specific human vulnerabilities, have frequently left a mark on human history.

Phytotherapy is attracting increased interest for several reasons. It differs from medical procedures in that it uses the whole herb, although there is often only one component of the plant that works effectively to manage the problem. Plants contain many natural chemicals or phytochemicals that interact with the active ingredient and help prevent any side effects. Medicinal herbs and spices are investigated for their suitability in daily diets for maintaining general wellness or preventing disease. In the past decade, natural health products, dietary supplements, foods with added value, or nutraceuticals have emerged due to the increasing demand for non-pharmaceutical healthcare products. Medical herbs and spices are potential sources for developing new, effective, and safe ingredients to capture a rapidly expanding opportunity in global marketplaces. This book presents up-to-date information on the chemical, pharmacological, and nutritional uses of medicinal herbs and spices in folk medicine, pharmaceuticals, the food industry, veterinary practice, and gastronomy.

This volume examines existing research documenting racial disproportionality and disparities in child welfare systems, the underlying factors that contribute to these phenomena and the harms that result at both the individual and community levels. It reviews multiple forms of interventions designed to prevent and reduce disproportionality, particularly in states and jurisdictions that have seen meaningful change. With contributions from authorities and leaders in the field, this volume serves as the authoritative volume on the complex issue of child maltreatment and child welfare. It offers a central source of information for students and practitioners who are seeking understanding on how structural and institutional racism can be addressed in public systems.
