Book Description
A l'exception des Malines dans le Gard, la production minière de zinc en France repose sur la blende, minerai recherché par les métallurgistes continentaux lorsque les gisements calaminaires deviennent insuffisants, vers 1880. Ces mines profitent des réseaux de chemins de fer pour écouler leurs produits, de l'avènement de la perforation mécanique, des téléphériques, des progrès des appareils de séparation et de lavage des minerais, puis, après la Première Guerre mondiale, de la flottation. Un historique de chacune de ces techniques nouvelles est dressé. Le site de référence est la mine Pyrénéenne de Sentein, qui produit 9,5 % du tonnage marchand français entre 1854 et 1953. Bien que la plupart des exploitants s'y conduisent comme des pirates, la nature des minerais et l'altitude les obligent souvent à se tenir à la pointe du progrès. C'est notamment le cas pour les premiers Anglais qui y investissent, ainsi qu'à Pierrefitte. Les sociétés Penarroya, Asturienne et Vieille Montagne prennent l'exploitation en main durant la Seconde Guerre mondiale. La baisse des teneurs et la chute des cours liée à la Guerre de Corée entraînent la fermeture de la mine en 1953, avant d'avoir pu y introduire les méthodes d'exploitation intensive américaines et malgré l'adoption pionnière en France d'un milieu dense

Book Description
This book represents a first considered attempt to study the factors that conditioned industrial chemistry for war in 1914-18. Taking a comparative perspective, it reflects on the experience of France, Germany, Austria, Russia, Britain, Italy and Russia, and points to significant similarities and differences. It looks at changing patterns in the organisation of industry, and at the emerging symbiosis between science, industry and the military.

Book Description
This intriguing study of Mexico's participation in world's fairs from 1889 to 1929 explores Mexico's self-presentation at these fairs as a reflection of the country's drive toward nationalization and a modernized image. Mauricio Tenorio-Trillo contrasts Mexico's presence at the 1889 Paris fair—where its display was the largest and most expensive Mexico has ever mounted—with Mexico's presence after the 1910 Mexican Revolution at fairs in Rio de Janeiro in 1922 and Seville in 1929. Rather than seeing the revolution as a sharp break, Tenorio-Trillo points to important continuities between the pre- and post-revolution periods. He also discusses how, internationally, the character of world's fairs was radically transformed during this time, from the Eiffel Tower prototype, encapsulating a wondrous symbolic universe, to the Disneyland model of commodified entertainment. Drawing on cultural, intellectual, urban, literary, social, and art histories, Tenorio-Trillo's thorough and imaginative study presents a broad cultural history of Mexico from 1880 to 1930, set within the context of the origins of Western nationalism, cosmopolitanism, and modernism. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1997.

Book Description
Products of war rather than revolution, the socialist regimes of Eastern Europe emerged in a global conjuncture defined by the aftermath of the Second World War. How did these regimes manage to overcome the domestic impact of the war and build socialism at the same time? This book shows how a commitment to productivity structured the transition from the period of postwar reconstruction to the take-off of industrial development during the late 1950s. Conceived as (1) pacification of labor relations, (2) the recovery of managerial authority, (3) monetarization of everyday life, (4) rationalization and (5) austerity, the politics of productivity provides a comprehensive conceptual framework for grasping together the end of the postwar period and the building of state socialism in Eastern Europe. By revealing how the social consequences of the Second World War were absorbed in the transition to authoritarian state socialism in the age of the rolling steel mill, this book carries implications for the way in which we may think about the aftermath of wars, reconstruction and development during the second half of the twentieth century.

Book Description
Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements
