PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. Providing space points along particle trajectories, the Pad Chamber
To understand the pathogenesis of autoimmune diseases we have to consider the problem from different angles. Animal models provide a tool to further understand these complex diseases, as the influence of genetic and environmental factors could be limited. Moreover, modern transgenic techniques have made it possible to study the role of certain genes and gene products in the development of diseases
The present thesis examines differences in post-decision processes between members of groups and individual decision makers. The empirical studies employed a decision theoretical framework based on Differentiation and Consolidation (Diff Con) Theory. Diff Con theory proposes that decision makers strive to achieve sufficient differentiation in their evaluation of one alternative versus competing al
Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. Among metal-containing drugs used tod
This thesis deals with the central carbohydrate metabolism and exopolysaccharide (EPS) formation in two different lactic acid bacteria (LAB): Lactobacillus reuteri and Pediococcus parvulus. LAB are traditionally used as starter cultures in the food industry. In general, LAB harbours one glycolytic pathway converting carbohydrates into lactic acid. However, L. reuteri ATCC 55730 was proven to use t
The aim of this thesis is to offer a contribution to the understanding of marketing work. In orthodox, mainstream marketing management literature, the work of marketing is commonly depicted as a fairly straightforward practice, technical in character, neutral in terms of social values and ideologies, operating within an objective and pre-given world. A counter picture to this idealised view of mar
Nuclear medicine is based on the radiotracer principle of George de Hevesy and the magic bullet concept by Ehrlich and focuses on the diagnosis, the treatment of diseases and the investigation of normal states within the human body using radiopharmaceuticals. A radiopharmaceutical is an atom or a chemical compound in which one or several atoms are replaced with a radionuclide. Several diagnostic a
This thesis investigates how play may benefit creativity in organizational contexts. Play and playfulness have previously been linked to creativity in children and adults, but empirical organizational research is scarce. A widely accepted definition of creativity is that it involves the production of something that is both novel and appropriate. Play is defined as a behavioral approach that is cha
Plants produce a multitude of different compounds that may have biotic effects. Artemisia annua, produces a compound used as a drug against multi-drug-resistant strains of Plasmodium falciparum, the parasite causing malaria. The compound, artemisinin, is a sesquiterpene and is an essential component for the production of artemisinin drugs against malaria. In a first critical step of the biosynthes
The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. Mass transfer has also been studied in the membrane. Heat and mass transfer has been studied in parallel plate channels, first in saturated ch
We wanted to improve tendon healing by adding a growth factor. Bone Morphogenetic Proteins (BMPs) are well known to stimulate bone healing and bone formation. The local environment is of major importance for cell differentiation after a BMP has been added. Cartilage Derived Morphogenetic Proteins (CDMPs) -1, -2 and -3 (BMP 14, 13 and 12 or GDF 5, 6 and 7) form a subgroup in the BMP-family and are
Life cycle environmental problems have been addressed by a number of strategies. However, the results are mostly lamentable because solutions are searched for within the same paradigms that give rise to the problems. This research questions the vision of linear material growth and searches for ways to sustain economic growth without putting the natural environment under stress. The research explor
The purpose of this study was to gain knowledge about and to understand the difference between the two genders as regards well-being and subjective health among unemployed immigrants, living in Sweden. The central aspect that is studied is, how family and social relations on the one hand, and the relation to the labour market on the other, influence immigrants and how they manage their situation.
