• Sommario/riassunto: Creep and fatigue are the most prevalent causes of rupture in superalloys, which are important materials for industrial usage, e.g. in engines and turbine blades in aerospace or in energy producing industries. As temperature increases, atom mobility becomes appreciable, affecting a number of metal and alloy properties. It is thus vital to find new characterization methods that allow an understanding of the fundamental physics of creep in these materials as well as in pure metals.Here, the author shows how new in situ X-ray investigations and transmission electron microscope studies lead to

• Sommario/riassunto: The female radical writers of the 1790s depict women attempting to use institutions such as the family, marriage, and motherhood to achieve social and political reform. Most striking about these novels is their depiction of the failure of these institutions to permit women to succeed in such attempts; these failures reveal a complex critique of the philosophies informing the reformist movement of the 1790s based upon the reformist culture's indifference to female concerns. </
