Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

Environmental awareness is driven mainly by the scarcity of natural resources and by more strict legal regulations. The modern enterprise policy should look at the relations between economic actions and ecological consequences. Ecoproduction is a new business approach which focuses on the most efficient and productive use of raw materials and natural resources in order to minimize footprints on the natural environment. This book aims to provide the state- of- the- art as well as new ideas of the environmental conscious operations management. The contributors present in the individual chapters problems related to: eco-friendly production technologies; recycling and waste reduction. Scope of topics discussed in this book covers also pollution prevention, energy efficiency. The authors describe problems of information management in complex systems

To survive and thrive in the competition, firms have strived to achieve greater supply chain collaboration to leverage the resources and knowledge of suppliers and customers. Internet based technologies, particularly interorganizational systems, further extend the firms'' opportunities to strengthen their supply chain partnerships and share real-time information to optimize their operations. "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" explores the nature and characteristics, antecedents, and consequences of supply chain collaboration from multiple theoretical perspectives. "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" conceptualizes supply chain collaboration as seven interconnecting elements including information sharing, incentive alignment, goal congruence, decision synchronization, resource sharing, as well as communication and joint knowledge creation. These seven components define the occurrence of collaborative efforts and allow us to explain supply chain collaboration more precisely. Collaborative advantages are also divided into five components to capture the joint competitive advantages and benefits among supply chain partners. The definitions and measures developed here examine some central issue surrounding supply chain development but this is also followed up with real-life managerial practicalities. This balance of theory and practical application makes "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" a strong resource for industry practitioners and researchers alike.

This book embarks on a contemporary analysis of the interaction of economics and law relating to air transport, delving into the major issues that plague the industry. It shows how some of the thorny and frustrating issues could be approached sensibly. Among the issues discussed are the anomaly of exponential growth of air transport which makes airline profitability continue to be poor; the legislative impediments in most countries that preclude direct foreign investment in the industry; the confounding and muddled mess behind the economics of aircraft engine emissions; and the inexplicable reality that, although civil aviation is primarily meant to meet the needs of the people of the world, State regulators have upended the equation and given priority to national interests over the interests of the passenger. The book will be of interest to economists and lawyers alike who deal with air transport issues, and also to academics and students in the area of transportation as well as regulators and airlines.

Cuando en los días 6 y 9 de agosto de 1945 se lanzaron sobre Hiroshima y Nagasaki las bombas atómicas que pusieron fin a la II Guerra Mundial, se mostró a la Humanidad la enorme potencia de la energia nuclear, a la vez que su enorme peligro destructivo. Esta carrera por la utilizacion de la energia nuclear para fines militares, antes que civiles, ha originado una importante oposicion a este tipo de energia, la cual aun perdura en la actualidad. Ademas, el uso de la energia nuclear ha vuelto a ser cuestionado a nivel mundial con motivo del seismo ocurrido el pasado dia 18 de marzo de 2011 en Japon, con una intensidad de 8.9 grados en la escala de Richter, el cual produjo un tsunami que origino grandes daños en la central nuclear japonesa de "Fukushima Dai-ichi". A nivel español, el debate nuclear se ha intensificado con la actuacion gubernamental acordando el cese definitivo de la central nuclear de Santa Maria de Garoña (Burgos) para el mes de julio de 2013 y con la ubicacion en Villar de Cañas (Cuenca) del Almacen Temporal Centralizado (ATC) de residuos nucleares de alta actividad. En este intenso debate social y politico, este trabajo tiene vocacion de constituir una util herramienta, y no solo juridica, para el acercamiento y comprension de las claves fundamentales del

EL USO E IMPLEMENTACIÓN DE INDICADORES AMBIENTALES EN EL SECTOR DE LA CONSTRUCCIÓN ESTÁN FUERTEMENTE INFLUENCIADOS POR ALGUNAS PECULIARIDADES COMO POR EJEMPLO, LA DISPERSIÓN GEOGRÁFICA, LA HETEROGENEIDAD DE SUS ACTIVIDADES, LA AUSENCIA DE CONTROL SOBRE EL DISEÑO DEL PROYECTO A EJECUTAR EL ALTO PORCENTAJE DE ACTIVIDADES SUBCONTRATADAS....

Las grandes transformaciones sociales vinieron a través de las ideas, luego fueron los inventos los que indicaron los cambios, ahora son los cambios tecnológicos tan extraordinarios, como por ejemplo Internet, los que fabrican las hojas de ruta de las sociedades. Seria bueno que, de nuevo, sea el talento el que ordene la escritura y no el brazo gigante de la tecnica y el interes el que oriente a nuestra civilizacion occidental. Hablar de energia en economia es como hablar de la sangre en el ser humano. La metafora que nos traslada Pau Solanilla y Alvaro Ponce en este libro apasionado, lleno de informacion y con toda intencion es que si las sociedades no son capaces de hacerse con el control de la energia que, al menos se nos permita gestionarla en nuestras casas o talleres. Mariano Guindal.

Human error plays a significant role in many accidents involving safety-critical systems, and it is now a standard requirement in both the US and Europe for Human Factors (HF) to be taken into account in system design and safety assessment. This book will be an essential guide for anyone who uses HF in their everyday work, providing them with consistent and ready-to-use procedures and methods that can be applied to real-life problems. The first part of the book looks at the theoretical framework, methods and techniques that the engineer or safety analyst needs to use when working on a HF-related project. The second part presents four case studies that show the reader how the above framework and guidelines work in practice. The case studies are based on real-life projects carried out by the author for a major European railway system, and in collaboration with international companies such as the International Civil Aviation Organisation, Volvo, Daimler-Chrysler and FIAT.
