Popular Abstract in Swedish Fotosyntesen är den mest grundläggande förutsättningen för människans överlevnad. Genom att absorbera solenergi och omvandla den till kemiskt bunden energi i form av energirika organiska molekyler, står fotosyntesen för nästan all tillförsel av energi till vårt ekosystem. Energin utnyttjas som mat, till oss och till djuren vi beror av, och som bränsle, fossilt eller färIn this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). It is a Mn-derived signal displaying clear hyperfine structure, centered at g=2, and is significantly broader than the well-known multiline signal from the S2 state, indicating the presence of MnII in

High-profile bribery scandals that involve powerful people and large sums of money are often the object of general indignation and legal action. When it comes to bribery of the everyday kind, however, it is far less obvious which gifts should be seen as bribes, be it in a moral or legal sense. Legal cases of this kind almost always include voices that strive to refute accusations of bribery. This

The hunter-gatherer groups of Southeast Asia represent a diverse range of adaptations. The so-called Negritos of the Andaman Islands, the Malay Peninsula and the Philippines have attracted particular attention because of long-standing claims that they represent traces of pre-agricultural Southeast Asia. Research on Andaman and Philippine prehistory has tended to maintain at least some components o

This paper describes differences between the capacity of Swedish and Danish students to attain life quality. This was carried out by examining the level of competence in four different groups of Swedish and Danish students, and is based on the hypothesis that the possession of competence is a premise for the development of life quality. Competence means the ability to make sense in complex situati

The paper proposes that intersubjectivity develops in children along a progression of five (more or less) distinct stages of semiotic development. The theoretical model within which this is couched is the Mimesis Hierarchy (MH) model (Zlatev & Andrén 2009). As in previous treatments, the MH-model focuses on bodily mimesis, its “precursors” (empathetic perception) and “post-developments” (conve

The severity of urinary tract infection (UTI) reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU) is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from hos
