The Schuylkill River flows more than 100 miles from the mountains of the Pennsylvania Coal Region to the Delaware River. It passes through five counties - Schuylkill, Berks, Chester, Montgomery, and Philadelphia - and its valley is home to more than three million people, yet few are aware of the hidden ruins and traces left by a pioneering 200-year-old inland waterway: the Schuylkill Navigation. Some of it is literally buried in their own backyards. Often called the Schuylkill Canal, this complex Navigation system actually boasted twenty-seven canals. The first of the anthracite-carrying routes in America, the 108-mile Navigation shadowed the Schuylkill River for nearly all its length. It once had more than thirty dams and slackwater pools, more than 100 stone locks, numerous aqueducts, and the first transportation tunnel in the nation. They were all built by hand starting in 1816. In the 1940s, as part of a massive environmental cleanup of the river, this important and influential infrastructure was largely dismantled - but not entirely. Two short sections of the watered canal get plenty of attention: the Oakes Reach at Schuylkill Canal Park near Phoenixville and the Manayunk Canal in Philadelphia. Both are popular recreational destinations. What happened to the rest of it? Photographer Sandy Sorlien resolved to find out. Over the course of seven years, she traveled upriver repeatedly to bushwhack along the riverbanks and to row and paddle in the river itself. Armed with camera and binoculars, loppers and trekking poles, nineteenth-century maps and modern satellite imagery, and abetted by local historians and an archaeologist, she found all sixty-one lock sites and explored most of the canal beds. Her photographs reveal a mysterious remnant landscape, evidence of a bold industrial innovation that spelled its own demise. The water pollution created by the coal industry and obstructive dams meant the end of a way of life for the towns that boomed along the canals, from Pottsville to Reading, Birdsboro to Phoenixville, Bridgeport to Philadelphia. Along with Sorlien's full-color plates and explanatory essays, Inland features a selection of historic images, rare historic Schuylkill Navigation Company maps, and early Philadelphia Watering Committee plans. The book also includes a foreword by renowned landscape scholar John R. Stilgoe, an essay on regional transportation history by Mike Szilagyi, Trails Project Manager for the Schuylkill River Greenways Natural Heritage Area, and an afterword by Karen Young, Director of the Fairmount Water Works Interpretive Center. A sweeping new Schuylkill River map by Morgan Pfaelzer connects it all. Inland is the first to present contemporary photographs from a survey of the entire Schuylkill Navigation, becoming an essential resource for future historians and a resonant visual history all its own.

From its earliest days, the cinema has enjoyed a special kinship with the railroad, a mutual attraction based on similar ways of handling speed, visual perception, and the promise of a journey. PARALLEL TRACKS is the first book to explore and explain this relationship in both historical and theoretical terms, blending film scholarship with railroad history. This highly original work reveals the profound impact that the railroad and the cinema have had on Western society and modern urban industrial culture. It will be eagerly received by those involved in film studies, American studies, feminist theory and the cultural study of modernity. It will also have appeal to general readers interested in silent films or in the history of the railroad.

With its low fares and friendly service, Pacific Southwest Airlines (PSA) was one of the most successful regional airlines in American history. Its distinctive orange, red, and white planes, complete with a beaming smile were immediately recognizable to those living on the West Coast. The airline was also known for employing beautiful and sociable flight attendants. Kenny Friedkin, the founder of PSA, started in 1949 with one leased DC-3 and expanded his fleet to serve millions of passengers each year. Although PSA is no longer in operation, its successful business model of low-priced, efficient service was copied by other airlines and today is considered the norm. In addition, former PSA employees still gather annually to relive the camaraderie they experienced as being a part of one of the most unique airlines of all time.

This is the story of dedicated men and women who are and were the backbone of aviation. They took all they had and bought 60 acres of land 35 miles from the city and proceeded to build an airport mostly with the blood, sweat and tears from their brows. None of them saw great wealth from their endeavor however, they were doing what they loved: living and sleeping with airplanes. They fueled them, repaired them, stored them and in some cases even taught in them.

Fuel injection systems and performance is fundamental to combustion engine performance in terms of power, noise, efficiency, and exhaust emissions. There is a move toward electric vehicles (EVs) to reduce carbon emissions, but this is unlikely to be a rapid transition, in part due to EV batteries: their size, cost, longevity, and charging capabilities as well as the scarcity of materials to produce them. Until these isssues are resolved, refining the spark-ignited engine is necessary address both sustainability and demand for affordable and reliable mobility. Even under policies oriented to smart sustainable mobility, spark-ignited engines remain strategic, because they can be applied to hybridized EVs or can be fueled with gasoline blended with bioethanol or bio-butanol to drastically reduce particulate matter emissions of direct injection engines in addition to lower CO2 emissions. In this book, Alessandro Ferrari and Pietro Pizzo provide a full review of spark-ignited engine fuel injection systems. The most popular typologies of fuel injection systems are considered, with special focus on state-of-the-art solutions. Dedicated sections on the methods for air mass evaluation, fuel delivery low-pressure modules, and the specific subsystems for idle, cold start, and warm-up control are also included. The authors pay special attention to mixture formation strategies, as they are a fundamental theme for SI engines. An exhaustive overview of fuel injection technologies is provided, and mixture formation strategies for spark ignited combustion engines are considered. Fuel Injection Systems illustrates the performance of these systems and will also serve as a reference for engineers who are active in the aftermarket, offering detailed information on fuel injection system solutions that are mounted in older vehicles.

Full color, richly illustrated book. This manual aims to gather and disseminate the modern OSD technology based on worldwide practice. Emphasis is now placed on the fact that the design of these structures is generally controlled by fatigue limit states. Details necessary to make these structures work require advanced fatigue evaluation techniques that must rest on accurate stress range calculations, which is possible with the use of the Finite Element Analysis (FEA) and/or prototype testing. The fatigue testing database has grown considerably over the last few decades, which has provided the necessary data for proper evaluation and detailing for fatigue resistance.

In this well established book, now brought up to date in a second edition, the Technical Editor of Performance Bikes' shows you how to evaluate your engine, how to assess what work you can undertake yourself, and what is best left to a specialist.

The great attraction of the two-stroke is its enormous potential, contrasted with its appealing simplicity. Armed with little more than a set of files, you can make profound changes to the output power of a two-stroke. But these changes will increase the
power only if you know what you are doing. Motor Cycle Tuning (Two-stroke)' will therefore guide you through the necessary stages which can enable a stock roadster engine can be turned into a machine capable of winning open-class races, for an outlay which is positively low by racing standards. Very few other books on engine development and most of these are either devoted to car engines or are out of date Promoted by PERFORMANCE BIKES

What was special about 1845 and why does it deserve particular scrutiny? In his much-anticipated new book, one of the leading authorities on the Victorian age argues that this was the critical year in a decade which witnessed revolution on continental Europe, the threat of mass insurrection at home and radical developments in railway transport, communications, religion, literature and the arts. The effects of the new poor law now became visible in the workhouses; a potato blight started in Ireland, heralding the Great Famine; and the Church of England was rocked to its foundations by John Henry Newman's conversion to Roman Catholicism. What Victorian England became was moulded, says Michael Wheeler, in the crucible of 1845. Exploring pivotal correspondence, together with pamphlets, articles and cartoons, the author tells the riveting story of a seismic epoch through the lives, loves and letters of leading contemporaneous figures.
