In the multi-disciplinary field of wind energy, students and professionals can often be uncomfortable outside their own specialist areas. This essential textbook explains the key aspects of wind turbine technology and its application in a single readable text. Covering a broad range of multi-disciplinary topics, including everything from aerodynamics through to electrical and control theory, to structures, planning, economics, and policy, this reference is an excellent toolkit for undergraduate students, postgraduate students, and professionals in the field of wind energy. Key concepts, including more challenging ones such as rotational sampling of turbulence, vortex wake structures, and reactive power management, are explained using clear language and simplifying illustrations including experimental graphs, photos, and line drawings.

Veganism as an ethics and a practice has a recorded history dating back to antiquity. Yet, it is only recently that researchers have begun the process of formalizing the study of veganism. Whereas occasional publications have recently emerged from sociology, history, philosophy, cultural studies, or critical animal studies, a comprehensive geographical analysis is missing. Until now. In fourteen chapters from a diverse group of scholars and living practitioners, VEGAN GEOGRAPHIES looks across space and scale, exploring the appropriateness of vegan ethics among diverse social and cultural groups, and within the midst of broader neoliberal economic and political frameworks that seek to commodify and marketize the movement. VEGAN GEOGRAPHIES fundamentally challenges outdated but still dominant human-nature dualisms that underpin widespread suffering and ecological degradation, providing practical and accessible pathways for people interested in challenging contemporary systems and working collectively toward less destructive worlds.

Moving heat and cold efficiently in urban areas is the main goal of district heating and cooling systems. By connecting suitable customer heat and cold demands with available heat and cold sources, the demands can be met by lower resource use in comparison to conventional heat and cold supply, such as boilers and air conditioners.<br/>The textbook contains chapters about the fundamental idea, energy markets, customer demands, load variations, supply, environmental impact, distribution, substations, system functioning, economics, planning, historical development, current and future use, organisation, and information sources concerning the flows of heat and cold in district heating and cooling systems.<br/>District heating and cooling is an interdisciplinary technology containing elements from many general technologies and methodologies such as combustion, heat transfer, piping, marketing, billing etc. Our mission has been to provide basic introductory knowledge about aspects typical of district heating and cooling, which is very vital for a basic understanding of, or very unique for, this niche technology.<br/>We have a rather broad range of readers in mind: District heating engineers, university students of engineering, and employees at district heating companies in general. We will be happy if urban planners, economists, policymakers and others interested in the topic will find that this book provides tangible and useful information about district heating and cooling.

This book presents several years of research into the history of America's post-World War II M-1 Helmet. It provides the most comprehensive look into the research, development, and production of the M-1 Helmet during this often overlooked period. All aspects of the M-1 Helmet are covered, as well as associated research and development programs that impacted the helmet, such as the Nylon Helmet Program. The book provides a detailed look at helmet production, including the helmet body, cotton duck liner, Combat Helmet Liner, parachutist's helmets, and camouflage helmet covers. The production history of every major manufacture is also provided. Every production helmet is covered with full color photographs, including detail shots and production markings. Also included are contract sheets, a contract number reference, military specification drawings, and photos of helmet samples and helmet production.
