Popular Abstract in Swedish Cellulära mekanismer vid ischemisk tolerans Stroke, hjärntrauma, hjärnblödning och övergående hjärtstillestånd, leder till minskat blodflöde till hjärnan (ischemi) och orsakar hjärnskador. Mot denna skadeutveckling finns ännu inte något medel för kliniskt bruk. I djurexperimentella ischemimodeller har man kunnat skydda hjärnan mot ischemiska skador genom att utsätta hjäA brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. Using this model we have demonstrated that ischemic preconditioning protects t

Urban Transport Development is a contribution to the ongoing global discussion on the future of urban transport. The main themes are how to cope with the complexity of urban transport development and the process of change including its determining factors. The role of leadership in the development process is the key issue. Main areas of discussion are the historical background, the diversity and c

Introduction of roughness by ribs in flow passages is a popular method of enhancing heat transfer in the cooling passages, e.g., of turbine blades and combustors. It is essential to accurately predict the enhancement of heat transfer generated by the ribs to ensure good design decisions. In most of the studies square ribs have been considered, but in practice such ribs may appear rounded due to im

Popular Abstract in Swedish Avhandlingen är en studie av kvinnors brevskrivning i Sverige under 1700-talet. Breven är skrivna av ett antal kvinnor från de högre samhällsskikten (adel och borgerskap) under 1780- och 1790-talen. Flertalet av breven är skrivna på svenska, men några också på franska. Huvudsyftet med avhandlingen är att undersöka relationen mellan idén om att kvinnor skrev annorlunda, This dissertation is a study of women's letter-writing in eighteenth-century Sweden. The letters are written by a number of women from the uppper classes (nobility and bourgeoisie) during the last two decades of the eighteenth century. The majority of the letters are written in Swedish, some however in French. The main aim is to examine the relationship between the idea of women as a special kind

In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g., mechanical stability of surfactant during the breathing cycle, the

Popular Abstract in Swedish Porträtt av kungar, krigare, ämbetsmän och andra gestalter från den karolinska epoken (1654-1718) hade kring sekelskiftet 1900 en särställning i svensk kultur. Många konsthistoriker var inspirerade av den nationalromantiska diktar- och konstnärsgenerationen och tolkade de karolinska porträtten som symboler för Sverige och för en historiskt förankrad nationell identitet.The subject of this thesis is portraiture and its context in Sweden during the Caroline era (1654-1718). Mainly, it focuses on portraits of the political élite, including the Royal family, and on the biographies of the artists that depicted those sitters. The dissertation consists of an introductory chapter and three longer case studies. In the introduction, there is a discussion of the early 20th
