[This book is written in French.] Vitale pour toute société humaine, l'eau est pour les Romains le symbole même de leur existence-depuis que Romulus, le fondateur, a été sauvé des eaux du Tibre-ainsi que de leur pouvoir sur les forces naturelles et sur les hommes. Ce livre montre comment ils ont répondu aux nécessités immédiates, mais aussi joint l'utile au plaisir, le futile à la grandeur. Avec une précision qui surprendra les ingénieurs et une suimplic-ité dont les profanes lui sauront gré, l'auteur retrace la quête obstinée de techniques souterraines et aériennes, qui permettent de capter les eaux dans les lointaines montagnes, de les conduire jusqu'aux villes, de les purifier, de les conserver et de les évacuer. On rencontre ici les Romains dans leur intimité, on entend leurs bavardages autour des fontaines, ou dans les latrines, on surprend leur admiration pour les empereurs évergètes qui leur offrent des thermes somptueux, mais on y trouve aussi les calculs des ingénieurs, leurs tâtonnements, leurs échecs et leurs réussites, et surtout la volonté de puissance d'un peuple qui, pour maîtriser la source de la vie, jetait à travers les plaines et par-dessus les val-lées profondes les arches puissantes et élégantes de ses aqueducs.
Underwater Welding contains the proceedings of the International Conference held at Trondheim, Norway on June 27-28, 1983 under the auspices of the International Institute of Welding. The book separates the papers of the conference into Portevin Lecture, General Survey, and another four sections. The Portevin Lecture part explains welding under water and in the splash zone; while the General Survey part talks about the technologies, practices, and metallurgy of underwater welding. The four sections detail the wet and dry welding; inspection and performance; physical, metallurgical, and mechanical problems; as well as repair and other application of the process.
This book investigates a corpus of royal inscriptions and literary texts, with special emphasis on those that are mythological and biblical, stretching over several millennia from the early days of Sumer to the Biblical period, in order to determine the ways in which the concept of water was used, in particular the way it functions in the political and theological ideology of the time. Three literary motifs are the object of a careful study : the crossing of water, the flood and the water of abundance. Though their study shows diversity in evolution, transmission and reception, it appears that their function is common at the heart of the Mesopotamian political theology of royal mediation.
Water management has become a major issue for public policies at any latitude. How and why this happened could not be assessed efficiently without developing a longitudinal and comparative analysis, such as the one in this book. Institutional arrangements for the provision and the use of water are peculiarly persistent as well as remarkably resilient: This makes them an ideal subject of an historical account. Not that history is worth writing about only when it treats immutable phenomena. On the contrary; its main purpose is to record changes and possibly explain them. But long-lasting continuity urges the scholar to venture into the remote past, since only there are to be discovered the initial causes and the deeper meanings of the institutions under scrutiny. Also, continuity makes the strength of path-dependency all the more evident and consequently underlines the weight of history.
