Mysterious nighttime lights near Brown Mountain in North Carolina's Pisgah National Forest have intrigued locals and visitors for more than a century. The result of a three year investigation, this book identifies both manmade and natural light sources--including some unexpected ones--behind North Carolina's most famous ghost story. History, science and human nature are each found to play a role in the understanding and interpretation of the lights people see.

Identifying the Jeep CJ series vehicles as the most popular off-road vehicles of all time may actually qualify as an understatement. They really are that popular. The CJ series arguably started after World War II with the CJ-2A being introduced to the masses, and while the early CJs have their share of enthusiasts, the largest group of enthusiasts began their love affair with the AMC-powered Jeep CJ-5s beginning in 1972. Joined by the longer-wheelbase CJ-7 models introduced in 1976, the CJ models were wildly popular through their discontinuation in 1986, when the Wrangler was introduced. These were the only models originally equipped with V-8 engines in any meaningful way. This era combined the ruggedness of the early Jeeps with some of the advancements and horsepower of a more modern era; it makes a platform that is both fun to own and to modify. Jeep guru Michael Hanssen covers all of the systems that can be upgraded to improve your Jeep's performance. Upgrades include suspension components such as springs, shocks, and steering modifications; driveline components including differentials, transmissions, transfer cases, and axles; engine upgrades including engine swaps; wheel and tire upgrades; aftermarket accessories; and armor such as skid plates, bumpers, brake upgrades, and more. Whether you are looking to get into serious off-roading or just want to make your classic CJ a little more fun, this book will be a valuable tool in your shop or library. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Arial}

This book explores how lighting systems based on LED sources have the ability to positively influence the human circadian system, with benefits for health and well-being. The opening chapters examine the functioning of the human circadian system, its response to artificial lighting, potential health impacts of different types of light exposure, and current researches in circadian photometry. A first case study analyzes the natural lighting available in an urban interior, concluding that it is unable to activate the human circadian system over the entire year. Important original research is then described in which systems suitable for artificial circadian lighting in residential interiors and offices were developed after testing of new design paradigms based on LED sources. Readers will also find a detailed analysis of the LED products available or under development globally that may contribute to optimal artificial circadian lighting, as well as the environmental sensors, control interfaces, and monitoring systems suitable for integration with new LED lighting systems. Finally, guidelines for circadian lighting design are proposed, with identification of key requirements.
