Book Description
Integrative Oncology explores a comprehensive, evidence-based approach to cancer care that addresses all individuals involved in the process, and can include the use of complementary and alternative medicine (CAM) therapies alongside conventional modalities such as chemotherapy, surgery, and radiation therapy. The number of integrative care programs is increasing worldwide and this book forms a foundation text for all who want to learn more about this growing field. This guide provides a thoughtful and generous perspective on integrative care, an outstanding overview of the exciting clinical opportunities these techniques can offer, and a guide to the new territories that all oncologists and CAM practitioners need to explore and understand.

Book Description
Evaluation, repair and rehabilitation of bridges are increasingly important topics in the effort to deal with the deteriorating infrastructure. For example, in the United States about 40 percent of the nation's 570,000 bridges are classified, according to the Federal Highway Administra tion's (FHW A) criteria, as deficient and in need of rehabilitation and replacement. In other countries the situation is similar. FHW A estimates the cost of a bridge replacement and reha bilitation program at 50 billion dollars. The major factors that have contributed to the present situation are: the age, inadequate maintenance, increasing load spectra and environmental contamination. The deficient bridges are posted, repaired or replaced. The disposition of bridges involves clear economical and safety implications. To avoid high costs of replacement or repair, the evaluation must accurately reveal the present load carrying capacity of the struc ture and predict loads and any further changes in the capacity (deterioration) in the applicable time span. Accuracy of bridge evaluation can be improved by using the recent developments in bridge diagnostics, structural tests, material tests, structural analysis and probabilistic methods. There is a need for an international exchange of advanced experience to increase the research effi ciency. The Workshop is organized on the premise that the exchange of existing American and European experience in the area of bridge evaluation, repair and rehabilitation is beneficial for both parties involved.

Book Description
The fourth Structural Materials Technology NDT Conference was held in Atlantic City, New Jersey, with over sixty speakers presenting on a wide variety of topics. The goal of this conference was to inform engineers and researchers of the new nondestructive testing/nondestructive evaluation (NDT/NDE) technologies and techniques available for use in transportation construction. The use of alternative materials is challenging NDT/NDE professionals to develop new methods or modify existing techniques to address quality control, quality assurance, and long-term monitoring of structures built or strengthened with these materials. One such alternative is fiber-reinforced polymer (FRP) products. This conference included papers on this topic and a panel discussion that focused on the future of NDT/NDE technologies for structures built or rehabilitated with FRP composites. These proceedings contain the 62 papers that were presented at the conference, arranged according to session number. An author index is included.

Book Description
Reinforced and pre-stressed concrete are widely used for the construction of infrastructures such as bridges, industrial structures, buildings, etc. Most of the time, the quality of the concrete mix is assumed to be guaranteed but due to the congestion of reinforcement and the quality control exercised during placing and vibrating, honeycombs and voids are likely to be present in the hardened concrete. The presence of voids leads to the early deterioration of concrete and corrosion also sets in. The corrosion of reinforcement causes damage to the cover concrete and also section loss in the area of steel. In the case of pre-stressed concrete members, the corrosion leads to a catastrophic failure without any warning. Hence, it becomes necessary to evaluate the condition of concrete using Non Destructive Techniques (NDT) and Partially Destructive Techniques (PDT). The Ultrasonic Pulse Velocity (UPV) method which is widely adopted till now gives the relative quality and integrity of concrete and is based on the transit time. The rebound hammer gives the quality of concrete in the cover zone based on the rebound number.

Book Description
This book gives information on non destructive techniques for assessment of concrete structures. It synthesizes the best of international knowledge about what techniques can be used for assessing material properties (strength) and structural properties (geometry, defects...). It describes how the techniques can be used so as to answer a series of usual questions, highlighting their capabilities and limits, and providing advices for a better use of techniques. It also focuses on possible combinations of techniques so as to improve the assessment. It is based on many illustrative examples and give in each case references to standards and guidelines.

Book Description
Les ponts en arc font actuellement face au double défi de protéger leur patrimoine et de rivaliser avec d'autres formes plus récentes de structures. La conservation des ponts en arc implique de multiples impératifs : une politique saine d'inspection et de suivi, des méthodes précises d'investigation, une évaluation fiable et un éventuel diagnostic, des moyens efficaces de maintenance, de réparation, de renforcement et d'élargissement. Pendant que des ouvrages existants sont réparés et revalorisés, de nouveaux ponts en arc, de -nies traditionnelles et à " l'échelle humaine ", continuent à se construire, en utilisant des matériaux et procédés améliorés et rentables, assurant longévité et respect de l'environnement. Au premier plan de cette continuité, les concepteurs des ponts en béton, dans les hémisphères Nord et Sud, s'efforcent avec succès de réaliser des portées en arc de plus en plus longues, frôlant les 400 mètres dans les années 1980. Récemment, sur d'autres sites spectaculaires, des records de portées ont été battus par trois ponts en arc respectivement en pierre, en béton, en tubes d'acier remplis de béton. Une telle avancée ne manquera pas d'inciter les ingénieurs à rechercher des formes d'arc encore plus audacieuses et élégantes. Sur le large éventail des thèmes proposés, de nombreux auteurs, de plus de vingt-cinq pays, ont apporté des contributions majeures rappelant que les ponts en arc n'ont rien perdu de leur actualité et que, malgré les leçons assimilées de leur prestigieux héritage, leur conception stimule toujours la créativité des ingénieurs et des architectes. Ces contributions sont réunies dans le présent volume édité à l'occasion de la Troisième Conférence internationale sur les Ponts en Arc, tenue à Paris en septembre 2001. Arch bridges face at present the double challenge of protecting their heritage and competing with other more recent structural forms. The conservation of the arch bridge heritage successively requires sound inspection and monitoring policies, accurate investigative methods, reliable assessment and eventual diagnosis, efficient means for maintenance, repair, strengthening and widening. While existing structures are being repaired and upgraded, new arch bridges, of traditional forms and on a "human scale", continue to be constructed, using improved and cost-effective materials and procedures, ensuring longevity and respect for the environment. In the forefront of this continuity, concrete bridge designers, in the northern and southern hemispheres, have successfully been striving for ever larger arch spans, closely approaching 400 m in the 1980's. Lately, at other spectacular sites, span records were beaten in three arch bridges respectively using stone, concrete and slender concrete-filled steel tubes. This breakthrough may encourage engineers to seek more daring and elegant forms of arch. On the broad spectrum of the suggested topics, numerous authors, from more than twenty-five countries, have recently offered major contributions, reminding that arch bridges have nothing lost of their appeal and that, for all the lessons learnt from their prestigious heritage, their design still simulates the creativity of engineers and architects. These contributions are put together in the present volume edited on the occasion of the Third International Arch Bridge Conference held in Paris in September 2001.
