The two-stroke engine has been developed to a degree that was not thought possible a few years ago. One of its virtues is that it is mechanically very simple, which is a contributing factor to its widespread use and varied application. Here, engine-tuning expert A. Graham Bell takes the reader through the various modifications that can be made to a two-stroke and its components to give maximum useable power output and mechanical reliability.

This volume gives an overview of the trends in Traffic and Transport Psychology. It reflects the considerable development of the most important factors for driving a road vehicle, and the variety of international research approaches.

The first part contains basic approaches and integrated models as well as general theories and their implementation into Traffic and Transport Psychology.

The second part deals with the driver, especially cognition, performance, social and differential effects and impairment. Important aspects are treated, such as speed perception, reaction times, interaction, risk acceptance, aggression and gender differences. Special chapters refer to performance and fatigue.

The third part focuses on safety, driver support, selection and influencing drivers by enforcement, training and programs for the rehabilitation of traffic offenders. Classic ergonomic methods are discussed as well as modern telematic devices, or trends regarding driver-assessment.

In the last part, current developments are presented in relation to better mobility and the protection of the environment. Questions are asked, such as whether we could reduce the use of cars, how travel behaviour can be modified or to what extent the use of alternatives to motor vehicles benefits safety as well as the environment.

This work is not only important for psychologists. It should be read by all transport professionals interested in the application of psychology to traffic.

U.S. automakers are suddenly awash in profits, and South Koreans and Europeans have gained market shares, while Honda, Nissan, and Toyota have curtailed production following the 2011 tsunami in Japan. Shortages of Japanese new cars and supplier disruptions will likely push used car prices through the roof well into 2012, so what should a savvy buyer do? The all-new "Lemon-Aid Used Cars and Trucks 2012-2013" has the answers, including: More vehicles rated, with some redesigned models that don't perform as well as previous iterations downrated.More roof crash-worthiness ratings along with an expanded cross-border shopping guide.A revised summary of safety- and performance-related defects that are likely to affect rated models.More helpful websites listed in the appendix as well as an updated list of the best and worst "beaters" on the market.More "secret" warranties taken from automaker internal service bulletins and memos than ever.

First published in 1994 in the NASA Monograph in Aerospace History series. From the introduction: "On 25 May 1961 President John F. Kennedy announced to the nation a goal of sending an American safely to the Moon before the end of the decade. This decision involved much study and review prior to making it public, and tremendous expenditure and effort to make it a reality by 1969. Only the building of the Panama Canal rivaled the Apollo program's size as the largest non- military technological endeavor ever undertaken by the United States; only the Manhattan Project was comparable in a wartime setting. The human spaceflight imperative was a direct outgrowth of it; Projects Mercury (at least in its latter stages), Gemini, and Apollo were each designed to execute it. It was finally successfully accomplished on 20 July 1969, when Apollo 11's astronaut Neil Armstrong left the Lunar Module and set foot on the surface of the Moon." Illustrated.

The How and Why of UFOs is the much anticipated sequel to Kenneth W. Behrendt's previous groundbreaking work on the subject, Secrets of UFO Technology. The present work begins with a detailed review of the revolutionary anti-mass field theory explanation for UFO propulsion and its secondary effects which is critical to understanding how these craft can easily overcome the usual limitations imposed by gravity and inertia upon our present massive earthly air and spacecraft. This cutting edge theory is then applied to several classic UFO cases to provide previously unsuspected insights into them. Even the often overlooked topic of small automated alien probes is explored as a highly detailed probe case, personally investigated by the author, is presented and analyzed in order to reveal the amazing interior structures of the object sighted.After providing an analysis of the planets of origin of advanced spacefaring extraterrestrial beings, the possible reasons for their visitations to our Earth are considered. The author then goes on to describe the most likely biological mechanism behind the mental telepathy process that is the principle mode of communication for most extraterrestrial beings and even suggests a variety of simple methods that might actually allow human researchers to communicate with the alien pilots of the UFOs now operating in Earth's atmosphere All of this is only a small sample of the many intriguing topics awaiting the reader in this abundantly illustrated volume. The many revelations found in The How and Why of UFOs are sure to delight and intrigue any student of ufology who wishes to explore this fascinating subject at its very deepest level.

First published in 1995 as volume 4 in the NASA "Monograph in Aerospace History" series. This study contains photographs and illustrations.

The airline industry is in a state of radical restructuring as its markets and key stakeholders (customers, airline labour and management groups, governments, and the financial community) adjust to the new aviation realities. Airline executives can be forgiven for being overwhelmed by technology proliferation, zestful new paradigm airlines, September 2001, business cycles, Iraq, SARS, and animal diseases. The leadership challenge for all carriers is now to select and execute appropriate business models, thinking both 'inside' and 'outside' the 'box', to turn conventional wisdom upside down to achieve dramatic increases in productivity. Some legacy carriers still need to create an effective strategy for much larger cycles that encompass major discontinuities. Burdened by past decisions, they are forced to fight with one hand tied behind their back to 'convert volume to value', to survive and prosper. Some new airlines have been at the forefront of shaping change, developing a vision of the mass-market, assessing the customer value of their core processes, and using a 'back-to-basics' business approach. Both groups should take a sideways glance at what works in other industries and implement those insights into actions.
