Sommario/riassunto

La noblesse est un thème porteur, et la Bretagne, différente du reste de la France par la forte densité et l'éclat changeant de sa population noble, offre pour la comprendre un champ d'analyse privilégié. Son exploration entraîne le chercheur, bien au-delà des simples sphères aristocratiques, jusqu'au coeur des sociétés traditionnelles. Les neuf «regards» rassemblés dans ce livre en fournissent la démonstration, que les auteurs se proposent de porter à la connaissance du public des recherches en cours, qu'ils tentent une synthèse de travaux publiés ou



qu'ils s'attachent à développer des problématiques renouvelées grâce aux méthodes d'investigation de la sociologie ou de l'anthropologie sociale que les historiens savent fort bien aujourd'hui adapter aux exigences de leur discipline. On a choisi d'adopter une chronologie longue, des temps féodaux à l'aube du XXe siècle, et de varier les angles d'approche, des statuts juridiques et des liens d'homme à homme au cadre domestique, des options politiques aux engagements économiques, des contrastes sociaux à l'idéalisation d'un modèle de vie. Il s'agit avant tout de souligner la diversité des formes du questionnement historique et de montrer, au travers des acquis et des interrogations qui demeurent, que les archives bretonnes sont encore loin d'avoir livré tous leurs secrets, et que la réflexion sur les systèmes et les comportements aristocratiques, loin d'être obsolète ou dénuée d'intérêt, reste d'une évidente actualité pour nos sociétés plébéiennes et démocratiques.

Sommario/riassunto

The handbook explains in plain terms why moldings shrink and warp, shows how additives and reinforcements change the picture, sets out the effect of molding process conditions, and tells why you never can have a single """"correct"""" shrinkage value. But that's not all. The handbook shows how to alleviate the problem by careful design of the molded part and the mold and by proper material selection. It also examines computer-aided methods of forecasting shrinkage and warpage. And most important of all, the handbook gives you the data you need to work with.  This is the most complete c
