Popular Abstract in Swedish I centrum för avhandlingen står det fotografiska porträttet. Min utgångspunkt har varit att kombinera olika teorier om kön med intresset för fotografi.

För att kunna göra det jämför jag f"Visiting Reality: Photography and Gender at the End of the Nineteenth Century" In the centre of the dissertation stands the photographic portrait.

Timber-glass composite I-beams were manufactured and tested in bending to failure. The glass web of the I-beam was adhesively bonded to the timber flanges using three different adhesives: Epoxy, Acrylate and Silicone. For the webs two types of 8 mm thick glass were used: annealed float and heat heat-strengthened glass. Before testing the beams with heat-strengthened glass, the residual-stress prof

LEVANDE ORD är ord som har kraft att förändra. Syftet med boken Levande ord för långtidssjukskrivna är att, likt kyrkans evangeliebok, presentera texter om livsnära ämnen, som även icke religiösa människor kan ta till sig.

By only account-ing for the direct consequences when analysing critical infrastructures, the

Människor är ständigt involverade i sociala relationer. Det gäller när vi möter andra ansikte mot ansikte, när vi kommunicerar mobilt och när vi i vår ensamhet begrundar våra liv.

Sociala relationer är alltså av avgörande betydelse i all social och personlig utveckling. I denna bok pre

Popular Abstract in Swedish När Immanuel Kant år 1795 lät publicera sin lilla skrift Om den eviga freden väckte den stor uppmärksamhet över hela Europa och översattes snart till flera språk.

Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. Aerosol particles are also involved in the earth’s radiation balance, both directly by scattering the sunlight and indirectly by influencing the clouds. All these effects are influenced by th

Work pace control, autonomy, learning new skills, or participation in company decision making are specific psychological factors included in the job control dimension. On the other hand, high absenteeism and poor health are symptoms used to associate with poor psychosocial working environment. This industry paper presents the e
