The authors of this volume illustrate recent trends in the design and application of accurate force fields. 15 papers reflect the present questions including the strategies for (i) the inclusion of the polarization energy and (ii) an optimal parametrization of models. They highlight the directions to follow as new exciting fields of application emerge. Expert authors discuss the optimization and parametrization of new models, put in perspectives the actual importance of the polarization energy, as well as review or propose new models explicitly for incorporating polarization. They also present models that are applied to difficult systems or challenging fields of application. Originally published in the journal Theoretical Chemistry Accounts, these outstanding contributions are now available in a hardcover print format. This volume is of benefit in particular to those research groups and libraries that have chosen to have only electronic access to the journal. It also provides valuable content for all researchers in theoretical chemistry.

Understanding Paleolithic animal exploitation requires a multifaceted approach. Inferences may derive from research on paleoenvironments and taphonomy, the development of new methods for interpreting seasonality patterns, and ethnoarchaeological observations. A full understanding of Paleolithic economies also requires a multiregional perspective. This volume brings together a group of scholars with research interests from across the globe to understand the nature of animal exploitation practices through the lens of taphonomy. The chapters include case studies on the types of animals that Paleolithic peoples hunted and gathered through time and space, and taphonomic analyses of non-human animal bone assemblages.

Are you keeping safe? Electrical wiring and appliances, overhead power lines, machinery, photocopiers, mobiles and cordless telephones, radio masts, TVs, tube trains, x-rays and laser beams are amongst the hundreds of everyday items that are now known to give off high levels of microwave radiation. Electromagnetic fields (EMFs) can be biologically active and capable of making changes to the structure of human and animal cells which are exposed to them. Long-term exposure is believed by an increasing number of scientists and environmentalists to be connected to tumours, fertility problems, behaviour and mood changes, concentration and memory loss, and also to affect melatonin production and impair our immune system repair mechanisms. The Powerwatch Handbook is a simple no-nonsense guide to EMFs and how to reduce their harmful effect. Alasdair and Jean Philips present their information in a practical, positive and lively way, in an easy-to-follow handbook style. EMF levels are graded using a star rating system, high level items are highlighted, and practical tips given in step-by-step, bullet point form.
