Sommario/riassunto |
|
Essentials of Radiation Heat Transfer is a textbook presenting the essential, fundamental information required to gain an understanding of radiation heat transfer and equips the reader with enough knowledge to be able to tackle more challenging problems. All concepts are reinforced by carefully chosen and fully worked examples, and exercise problems are provided at the end of every chapter. In a significant departure from other books on this subject, this book completely dispenses with the network method to solve problems of radiation heat transfer in surfaces. It instead prese |

Sommario/riassunto |

« Des électriciens ? Des gaziers ? Des métiers ? Qu'est-ce que cela peut bien être ? Aujourd'hui nous avons des 'commercial', des 'consultants', des 'intervenants extérieurs', des 'intérimaires'. Le client reçoit des services, à la hauteur, ni plus ni moins, de la qualité qu'il a payée. » |

Entendra-t-on un jour ce discours ? Les auteurs de ce livre espèrent que non. En tout cas, ils nous racontent l'aventure peu commune d'un groupe d'hommes et de femmes de la région du Havre qui, pendant une cinquantaine d'années, ont réussi à concilier un travail digne, une technique d'avant-garde et le service de la collectivité. Soixante-dix personnes, du terrassier au cadre dirigeant, nous racontent leur savoir-faire, leur vie, la nationalisation, l'après-guerre, mai 1968, le charbon, le fioul, les réseaux et les raccordements, leurs craintes et leurs espoirs. Autour de trois sites principaux, le centre de production d'électricité nucléaire de Paluel, le centre de production thermique du Havre, le centre de distribution d'EDF-GDF, nous découvrons leur histoire, des chauffeurs de fours et des lampadaires à gaz aux ordinateurs. |
