Upon encounter with antigen, the B lymphocyte population responds by producing a diverse set of antigen-specific antibodies of various isotypes. The vast size of the responding populations makes it very difficult to study clonal evolution and repertoire composition occurring during these processes in humans. Here, we have explored an approach utilizing the H-EPSILON-encoding transcriptome to inves
The available evidence suggests that both genes and environment play a crucial role in the development of juvenile-onset myopia. When the human visual system is examined from an evolutionary perspective, it becomes apparent that humans, living in the original environmental niche for which our species is genetically adapted (as hunter-gatherers), are either slightly hypermetropic or emmetropic and
The metabolites of arachidonic acid are well connected to pathological situations such as inflammation, cancer and asthmA. Sheng et al. [7] found that COX-2 is upregulated in colon cancer tissue and tumor cell lines indicating that COX-2 is involved in colon cancer. This is supported by studies showing that patients treated with nonsteroidal anti-inflammatory drugs, inhibitors of COX-2, exhibit a
An in-depth photoionization study of the inner-valence electrons in HCl and DCl has been performed using synchrotron radiation. A series of photoelectron spectra of HCl were obtained at a resolution of 23 meV over the binding energy range 25-30.5 eV at various excitation energies and at two different electron collection angles relative to the plane of polarization of the undulator radiation. In ad
The role of attention in speeded Garner classification of concurrently presented auditory and visual signals was examined in 4 experiments. Within-trial interference (i.e., congruence effects) occurred regardless of the attentional demands of the task. Between-trials interference (i.e., Garner interference) occurred only under conditions of divided attention when making judgments about auditory si
Electronic structure of two conjugated polymers, PPV and its derivative DIOXA-PPV, are studied by quantum-chemistry methods. Good agreement between the calculations and available experimental data validates the applied methods and enables us to draw conclusions about properties of excitons and polarons in these polymers. In particular, simultaneous use of different correlation plots in atomic site
This thesis discusses "social work" as part of missionary work during Hans Egede´s mission in Greenland (1721-1736) and the starting period of the Norwegian Saami mission (1888-1900). The discussion is focused by connecting it to Habermas´s discussion of "The structural transformation of the public" (1989). The discussion includes an analysis of the complexity of contemporary ideas. Missionary wor

In a retrospective analysis of 450 patients with rheumatoid arthritis the cervical films were reviewed to detect vertical dislocation of the C1 and C2 vertebrae. A frequency of 10 per cent was found among all patients and of 24 per cent among those with cervical arthritis. The authors' method of measuring vertical dislocation at conventional radiography turned out to be superior to the method of M
This thesis explores the changing patterns of employment and income assimilation among male immigrants to Sweden. In brief, the results of this work are that immigrants have been facing an increasingly difficult time integrating into the Swedish economy. This difficulty has not been caused by decreasing “quality” of the newer immigrant cohorts, as has often been the argument in the literature. Rat
This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta
Ett försök att tänka om och tänka nytt när det gäller definitionen av begreppet politisk teater utifrån två aktuella iscensättningar.
Can a deliberate enhancement of the natural uptake of atmospheric carbon dioxide in forests and agricultural lands contribute to the efforts to mitigation anthropogenic climate change? This is a question that has generated a great deal of debate and controversy since the inception of the multilateral climate negotiations in the early 1990s. This thesis offers an analysis of how this debate has pla

Food grain markets are special in the sense that farmers will, likely, be consumers of the crops they produce. This study examines smallholder market participation on the Ugandan maize market, and, furthermore, explores possible connections to rural poverty. A probit model of market participation is employed, and I work with data from a household survey conducted between 1999 and 2000. A number of
