The preparation of donor (D)-photosensitizer (S) arrays, consisting of a manganese complex as D and a ruthenium tris(bipyridyl) complex as S has been pursued. Two new ruthenium complexes containing coordinating sites for one (2a) and two manganese ions (3a) were prepared in order to provide models for the donor side of photosystem II in green plants. The manganese coordinating site consists of bri

A text that sees the American film director Steven Spielberg as an audiovisual lecturer of history. In the analysis how Saving Private Ryan depicts the past, aesthetic and technical considerations are dealt with at the same time as more general and historiographic topics are problematized.

Popular Abstract in Swedish Inledning Kreativitet kan definieras på många olika sätt. I denna avhandling definieras kreativitet som ”ett generativt eller produktivt nytt sätt att uppleva verkligheten och sig själv på”, vilket är en något modifierad version av Smith och Carlssons (1990) kreativitetsdefinition. Det produktiva sättet att se på verkligheten uppkommer just av att man kan rekonstruera Four studies on creativity, imagination and self-image in 10-year-old children constitute the basis of this dissertation. A total of 179 participants were involved. Study I investigated two new creativity measurements comprising The Drawing Task, which had its starting-point in a brief story, and The Activity Questionnaire, which included questions about the children’s spare time activities. The h

Using antenna arrays for direction of arrival (DoA) estimation and source localization is a well-researched topic. In this paper, we analyze virtual antenna arrays for DoA estimation where the antenna array geometry is acquired using data from a low-cost inertial measurement unit (IMU). Performance evaluation of an unaided inertial navigation system with respect to individual IMU sensor noise para

The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. We have investigated what characteristics of emulsions that the NMR self-diffusion technique can shed light on. The diffusion behavior of the liquid inside th

The densification of mobile networks in order to meet increased capacity demands is ongoing, needed and costly. A few papers have been published based on the insight that the fixed broadband networks offer a multitude of sites, for instance our homes, for potential small cell deployment providing backhaul capacity and power without site costs. However, in order to reach economical large-scale bene

Texten tar upp gränsmotivet i jugoslavisk film, framför allt genom att lyfta fram två filmer, Innan regnet faller (Pred Dozhdot, Mancevski, 1994) och Ingenmansland (Nicija zemlja, Tanovic, 2001). Dessutom diskuteras begrepp som jugoslavisk och postjugoslavisk film.

Mankind is already spending beyond the capacity of its planet and trends look very scaring. Big changes in human behaviour are urgent. As pointed out by others there are many ways how Ergonomics/Human Factors/ could contribute to such changes. The aim of this paper is to discuss some lessons learnt from safety performance in aviation and trans¬formed to sustainability, especially the concepts sust

In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou

Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. Because of this, analytical methods with specific p
