Popular Abstract in Swedish Ett av de viktigaste målen för astronomin är att förstå var vi kommer ifrån. Det är naturligtvis många steg som skall förstås, och vart och ett av dessa steg i människans för-förhistoria är komplicerat, så man skall inte förvänta sig att en enskild doktorsavhandling behandlar mer än ett litet hörn av ett av dessa steg. Mitt bidrag gäller förståelsen av hur vår egen galIn order to understand the formation and evolution of the Galaxy it is imperative to know when different components formed. This means at the most basic level that we need to know the ages of stars. The present work demonstrates the many problems inherent in determining the ages of stars through comparison with stellar evolutionary models. Furthermore, solutions to some of these problems are prese

In this paper, four major parameters of fresh water production from saline sources are discussed. The parameters are desalination technology type, water sources input type, energy sources and productions cost per cubic meter. Five different types of desalination technology are presented and bench-marked for long-term use. RO and MSF are dominant technologies. Six different input water sources are

The 2009 Swedish Church history yearbook contains eight articles and reviews of 62 different books in Scandinavian and International Church history.

Using the metaphores of Haute Couture and Prêt à porter we would like to examine some of the fashions that have been spread in the Swedish health care sector the past two decades. Who are the fashion makers? Who dicides what to import and why? Who are the models demonstrating the last fashion? most of all we wonder if the Haute Couture gets transformd into Prêt à Porter so that it suites and becom

The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications. Starch hydrolysing alkaliphilic b

Here we introduce the idea of virtual city experimentation: a design approach to catalyse action in the context of rapidly emerging disruptive challenges to the fabric and life of cities. In the meaning we give to the term, the concept of virtual experimentation owes little to the contemporary association of ‘virtual’ with ‘digital’, or ‘on-line’. Independent of any technology used in the process,
