Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments. Development of the sources has been accompanied with equa

Application of two-photon laser-induced fluorescence for single-shot visualization of carbon monoxide in a spark ignited engine

Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. The Gram-positive bacterium Enterococcus faecalis is found i

New high-efficiency power cycles and environmentally friendly cycles have introduced combustion atmospheres that differ from the traditional hydrocarbon-air mixtures. Wet cycles, solid oxide fuel cell with a gas turbine (SOFC-GT), CO₂ separation/capture and biogas combustion are processes that involve high concentrations of inert gases such as H ₂O, CO₂ and N₂

Fires in school buildings caused by arson are a major problem in Sweden. The costs of these fires are disproportionately high compared to the costs of fires in buildings in general, and it has been shown that fires that start outside of the building in connection with an exterior wall, so called exterior fires are especially problematic. However, technical systems can be used to mitigate the conse

We study two-sided ("marriage") and general pairing ("roommate") problems. We introduce "sequences," lists of matchings that are repeated in order. Stable sequences are natural extensions of stable matchings; case in point, we show that a sequence of stable matchings is stable. In addition, stable sequences can provide solutions to problems for which stable matchings do not exist. In a sense, they

The isolation of male and female DNA is an important step in the analysis of sexual assault evidence. A vaginal swab with female epithelial cells and male sperm cells is obtained from the female, and it is vital to separate the male and female fractions in order to obtain a single-source DNA profile of the suspect. In the case of a low abundance of sperm cells, it is very important that no cells a

After several years of disussions, tests, investigations and additional tests, the suppliers and retailers within the Swedish business sector for food and commodities formed a jointly owned, non-profit company in 1997, which subsequently started in physical operations in 2000. This company, Svenska Retursystem AB (www.retursystem.se), is now responsible for introducing returnable transport packagi

Popular therapeutic culture—such as self-help books, TV programmes, and Internet resources—is growing rapidly and posing important questions for feminist research and politics. On the one hand, it can be seen as a challenge to the public sphere in terms of what can be shown and said and by whom, with the emancipatory potential of giving political credentials to the personal. On the other, it can b

The aim of this dissertation is to analyse the early writings of Arthur Machen (1863?1947) by focusing on three aspects of literary production: the field, the author, and the text. In all these aspects position-takings in the field, the construction of an author's identity, and textual production ? Machen's early career is informed by a particular and idiosyncratic notion of aesthetic creation, re
