Sommario/riassunto

This book is an examination of some of the principal issues arising from the study of the kings’ sagas, the main narrative sources for Norwegian history before c. 1200. Providing an overview of the past two decades of scholarship, it discusses the vexed relationship between verse and prose and the reliability as historical sources of the verse alone or the combination of verse and prose; the possibility and extent of non-native influence on the composition of these texts; and the function of the past, in particular given that most of the historiography



of Norway was produced in Iceland. This book aims to stimulate studies of medieval Scandinavian historiography with its critical perspective on the texts and the scholarship, while also providing a useful work of reference in order to make this area of research accessible to scholars in cognate fields.

Sommario/riassunto

Atoms and molecules in all states of matter are subject to continuous irregular movement. This process, referred to as diffusion, is among the most general and basic phenomena in nature and determines the performance of many technological processes. This book provides an introduction to the fascinating world of diffusion in microporous solids. Jointly written by three well-known researchers in this field, it presents a coherent treatise, rather than a compilation of separate review articles, covering the theoretical fundamentals, molecular modeling, experimental observation and techni
