This book provides a comprehensive basics-to-advanced course in an aero-thermal science vital to the design of engines for either type of craft. The text classifies engines powering aircraft and single/multi-stage rockets, and derives performance parameters for both from basic aerodynamics and thermodynamics laws. Each type of engine is analyzed for optimum performance goals, and mission-appropriate engines selection is explained. Fundamentals of Aircraft and Rocket Propulsion provides information about and analyses of: thermodynamic cycles of shaft engines (piston, turboprop, turboshaft and propfan); jet engines (pulsejet, pulse detonation engine, ramjet, scramjet, turbojet and turbofan); chemical and non-chemical rocket engines; conceptual design of modular rocket engines (combustor, nozzle and turbopumps); and conceptual design of different modules of aero-engines in their design and off-design state. Aimed at graduate and final-year undergraduate students, this textbook provides a thorough grounding in the history and classification of both aircraft and rocket engines, important design features of all the engines detailed, and particular consideration of special aircraft such as unmanned aerial and short/vertical takeoff and landing aircraft. End-of-chapter exercises make this a valuable student resource, and the provision of a downloadable solutions manual will be of further benefit for course instructors.
This groundbreaking book presents a unique and practical approach to the evolving field of exercise oncology - the study of physical activity in the context of cancer prevention and control. Presenting the current state of the art, the book is sensibly divided into four thematic sections. Following an opening chapter presenting an overview and timeline of exercise oncology, the chapters comprising part I discuss primary cancer prevention, physical activity and survivorship, and the mechanisms by which these operate. Diagnosis and treatment considerations are discussed in part II, including prehabilitation, exercise during surgical recovery, infusion and radiation therapies, and treatment efficacy. Post-treatment and end-of-life care are covered in part III, including cardio-oncology, energetics and palliative care. Part IV presents behavioral, logistical and policy-making considerations, highlighting a multidisciplinary approach to exercise oncology as well as practical matters such as reimbursement and economics. Written and edited by experts in the field, Exercise Oncology will be a go-to practical resource for sports medicine clinicians, family and primary care physicians, oncologists, physical therapy and rehabilitation specialists, and all medical professionals who treat cancer patients.

Future titles will cover: anger, psychosis, disturbed children, self-harming, obesity, workplace stress, antisocial behaviour, ageing, disability and saving families.
Why would anyone say "Let's stick wires into someone's brain, run voltage through it, and see what happens!"? So asks Jackie Hunt Christensen in "Life With a Battery-Operated Brain: A Patient's Guide to Deep Brain Stimulation Surgery for Parkinson's Disease." Author Christensen answers this question - and more - in her unique and comprehensive book, as she has first-hand knowledge of the procedure commonly referred to as DBS. She herself lived with Parkinson's disease for more than seven years before electing to be evaluated for DBS surgery. It was not a fast and easy choice. For Christensen, a fear of DBS surgery - which involves placing one or two electrical wires inside the brain - and its potential complications had to be weighed against quality of life without the surgery, a life of increasing parkinsonian symptoms and a growing pharmacopeia of medications, which might help control her symptoms but which could have devastating long-term effects on her body. Ultimately, she was deemed a good candidate for the surgery, and DBS seemed like her only logical option - a choice that has been validated post-surgery, as Christensen now enjoys life with most of her motor symptoms well controlled.

Lockheed Martin (NYSE: LMT) is an American global aerospace, defense, security, and advanced technology company with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in Bethesda, Maryland, in the Washington Metropolitan Area. Lockheed Martin employs 123,000 people worldwide. Robert J. Stevens is the current Chairman and Chief Executive Officer. Lockheed Martin is one of the world's largest defense contractors; In 2009, 74% of Lockheed Martin's revenues came from military sales. It received 7.1% of the funds paid out by the Pentagon. Lockheed Martin operates in four business segments. These comprise, with respective percentages of 2009 total net sales of $45.2 billion, Aeronautics (27%), Electronic Systems (27%), Information Systems & Global Solutions (27%), and Space Systems (19%). In 2009 US Government contracts accounted for $38.4 billion (85%), foreign government contracts $5.8 billion (13%), and commercial and other contracts for $900 million (2%). In both 2009 and 2008 the company topped the list of US Federal Contractors. The company has received the Collier Trophy six times. Most recently (in 2001) for being part of developing the X-35/F-35B LiftFan Propulsion System, and again in 2006 for leading the team that developed the F-22 Raptor fighter jet. Lockheed Martin is currently developing the F-35 Lightning II. Merger talks between Lockheed Corporation and Martin Marietta began in March 1994, with the companies announcing their $10 billion planned merger on August 30, 1994. The deal was finalized on March 15, 1995 when the two companies' shareholders approved the merger. The segments of the two companies not retained by the new company formed the basis for the present L-3 Communications, a mid-size defense contractor in its own right. Lockheed Martin later spun off the materials company Martin Marietta Materials. Both companies contributed important products to the new portfolio. Lockheed products included the Trident missile, P-3 Orion, F-16 Fighting Falcon, F-22 Raptor, C-130 Hercules, A-4AR Fightinghawk and the DSCS-3 satellite. Martin Marietta products included Titan rockets, Sandia National Laboratories (management contract acquired in 1993), Space Shuttle External Tank, Viking 1 and Viking 2 landers, the Transfer Orbit Stage (under subcontract to Orbital Sciences Corporation) and various satellite models. On April 22, 1996, Lockheed Martin completed the acquisition of Loral Corporation's defense electronics and system integration businesses for $9.1 billion, the deal having been announced in January. The remainder of Loral became Loral Space & Communications. Lockheed Martin abandoned plans for a $8.3 billion merger with Northrop Grumman on July 16, 1998, due to government concerns over the potential strength of the new group; Lockheed/Northrop would have had control of 25% of the Department of Defense's procurement budget. Lockheed Martin provided NASA with measurements in US Customary force units when metric was expected, resulting in the loss of the Mars Climate Orbiter at a cost of $125 million. The cost for spacecraft development was $193.1 million.

This book presents a comprehensive, contrastive account of the phonological structures and characteristics of Icelandic and Faroese. It is written for Nordic linguists and theoretical phonologists interested in what the languages reveal about phonological structure and phonological change and the relation between morphology, phonology, and phonetics. The book is divided into five parts. In the first Professor Árnason provides the theoretical and historical context of his investigation. Icelandic and Faroese originate from the West-Scandinavian or Norse spoken in Norway, Iceland and part of the Scottish Isles at the end of the Viking Age. The modern spoken languages are barely intelligible to each other and, despite many common phonological characteristics, exhibit differences that raise questions about their historical and structural relation and about phonological change more generally. Separate parts are devoted to synchronic analysis of the sounds of the languages, their phonological oppositions, syllabic structure and phonotactics, lexical morphophonemics, rhythmic structure, intonation and postlexical variation. The book draws on the author's and others' published work and presents the results of original research in Faroese and Icelandic phonology.
