The Danish Resources c. 1000-1550

Growth and Recession

By: Nils Hybel,Bjorn Poulsen

This pioneering work presents the first comprehensive economic history of medieval Denmark. It puts data produced by more than a century of historical research into a new context and includes a multitude of information based on primary research. The book abounds in knowledge of natural and human resources, rural life, urban industries, tax and commodity trade. Arguing that the development of the Danish resources from the eleventh to the middle of the fourteenth century cannot be viewed simply as a period of prosperity, and conversely that the Late Middle Ages were characterized as much by growth as by recession, the book places itself in an international historiographical controversy. The Danish Resources will become an indispensable standard work for students of Danish and north European medieval history.

Silicate Glasses and Melts

Properties and Structure

By: Bjorn Mysen,Pascal Richet

This book describes the structure-property-composition relationships for silicate glasses and melts of industrial and geological interest. From Antiquity to the 20th century, an introductory chapter presents this subject in a historical perspective. Basic concepts are then discussed in three chapters where attention is paid to the glass transition and its various consequences on melt and glass properties, to the structural and physical differences between amorphous and crystalline silicates, and to the mutual relationships between local order, energetics and physical properties. With pure SiO2 as a starting point, compositions of increasing chemical complexity are successively dealt with in a dozen chapters. The effects of network-modifying cations on structure and properties are first exemplified by alkali and alkaline earth elements. The specific influence of aluminum, iron, titanium, and phosphorus are then reviewed. With water, volatiles in the system COHS, noble gases, and halogens, the effects of volatile components are also described. The last chapter explains how the results obtained on simpler melts can be applied to chemically complex systems. In each chapter, physical and chemical properties are described first and followed by a review of glass and melt structure. When possible, pressure effects are also considered.*From SiO2 to complex silicate compositions, the physical and chemical properties of melts and glasses of geological and industrial interest*Structural characterization of melts and glasses, from ambient to high pressure and temperature*From basic concepts to an advanced level, a consistent description of the structure-property-composition relationships in glasses and melts

Cool It

By: Bjorn Lomborg

Bjorn Lomborg argues that many of the elaborate and staggeringly expensive actions now being considered to meet the challenges of global warming ultimately will have little impact on the world’s temperature. He suggests that rather than focusing on ineffective solutions that will cost us trillions of dollars over the coming decades, we should be looking for smarter, more cost-effective approaches (such as massively increasing our commitment to green energy R&D) that will allow us to deal not only with climate change but also with other pressing global concerns, such as malaria and HIV/AIDS. And he considers why and how this debate has fostered an atmosphere in which dissenters are immediately demonized.
