Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. Transient anisotropy, obtained from different polarizations of light, was employed to trace the dipole m

The emission composition is measured for a prototype burner while varying the equivalence ratio in discrete portions of the burner. The burner is a three sector system, consisting of a separate igniter, pilot/stabilizer and main burner. The design allows for discrete control of equivalence ratio in each of the three sectors. The ignition sector, designated RPL (Rich- Pilot-Lean), operates from ric

Knowledge and experience of human and technological problems on long-duration missions to Moon and Mars, is at best minimal or worst-case non-existent, as these expeditions are yet to be undertaken. Problems stemming from isolation, inter-group relationships, human response to and interaction with spacecraft interiors in a confined isolated environment have been studied, but in limited ways. On fu

The thesis presents a rheological study on wheat flour dough, in relation to the structural influence of the different dough constituents, added components and mixing time. Rheological investigations have been focused on measurements at small deformations, including dynamic oscillation and stress relaxation, although complementing measurements have been performed in large deformation viscosity exp

This article deals with depictions of humans during the Vendel and Viking Age. While in earlier research, the iconographic approach has been predominant, the point of departure here are the functions pictures may have had in oral societies. As a new approach, the method of context analysis is presented. The main question is how depictions have been used differently by different social groups. In t

Objective: To study reproduction in a representative group of anorexia nervosa (AN) cases. Method: Fifty-one adolescent-onset AN cases (48 women; three men), originally recruited after community screening, and 51 matched comparison cases (COMP) were interviewed 18 years after AN onset at a mean age of 32 years, regarding pregnancies and early development of the children. Results: The result
