Paperback. Condition: new. Paperback. The XB-40 and XB-41 were secret, little-known experimental modifications of the B-17F and B-24D, respectively, into heavily-armed bomber gunships sometimes referred to as bomber escorters.They were developed during early World War II in response to the lack of a USAAF long-range fighter aircraft able to escort and protect regular B-17 formations making the round trip from Britain deep into Germany. Unfortunately, these protecters were found wanting in several ways - after the addition of guns and ammunition they became overweight and tail-heavy causing center of gravity problems. Each encountered numerous delays in the development and delivery of their various armament additions and improvements, particularly the Bendix chin turret.In the end, the YB-40 participated in only 14 lackluster operational service test missions during mid-1943 before being withdrawn from service. The XB-41 Liberator never saw operational testing before also being cancelled for its poor performance. The failure of the gunship concept left a huge hole in the capabilities of the Eighth Air Force. However, it spurred the adoption of the Merlin-powered P-51 Mustang, the outstanding escort fighter that was key to Allied victory in the air war over Europe.Using many formerly-classified documents from his large microfilm collection, William Wolf presents their previously-unpublished history. It describes in depth for the first time the politics and development and associated problems of both escorter types. Before the P-51 Mustang, the USAAF planned to use heavily-armed converted Flying Fortresses and Liberators to escort the Eighth Air Force's formations over Germany. This is the first history of their development, role, and failure, by an expert USAAF historian. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Paperback. Condition: New. This book features four peer-reviewed reviews on the economics of key elements of agriculture.The first chapter describes the economic potential for the widespread adoption of agricultural robotics worldwide, focussing primarily on adoption in low- and middle-income countries. The chapter also considers the broader implications of agricultural robotics adoption on the farm sector.The second chapter explores the large and diverse literature on the economics of nitrogen in agriculture and the economics of off-farm impacts from nitrogen fertilisation. The chapter also considers the over-application of nitrogen fertilisers and their contribution to nitrogen pollution.The third chapter summarises recent advances in the development of novel integrated weed management (IWM) strategies and the economic consequences of their use in farming systems. The chapter also reviews the economics of different IWM strategies and the contrasting approaches used to assess their efficiency.The final chapter discusses the use of groundwater for agricultural use and how unregulated overdevelopment of this key resource poses a threat to its sustainability.

Paperback. Condition: new. Paperback. Merriam Press Military Monograph 53. Fifth Edition (April 2012).
