This study presents the concentrations of about 50 metals and ions in 33 different brands of bottled waters on the Swedish market. Ten of the brands showed calcium (Ca) concentrations <= 10 mg L-1 and magnesium (Mg) levels < 3 mg L-1, implying very soft waters. Three of these waters had in addition low concentrations of sodium (Na; < 7 mg L-1), potassium (K; < 3 mg L-1) and bicarbonate (HCO3; <= 3

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

The helicity dependence of the total cross section for the (gamma) over right arrow(p) over right arrow -> p pi(0)pi(0) reaction has been measured for the first time at incident photon energies from 400 to 800 MeV. The measurement, performed at the tagged photon beam facility of the MAMI accelerator in Mainz, used the large acceptance detector DAPHNE and a longitudinally polarized frozen-spin targ

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

To use conventional ray tracing methods in Monte Carlo simulation of the collimator in a scintillation camera system can be time consuming. It is however necessary to take collimator interactions into account when simulating radionuclides emitting high-energy photons that can penetrate the septa in the collimator. In this work a statistical collimator algorithm, based on the Delta-Scattering metho

This article compares and contrasts male immigrant labor market experiences in Sweden and Denmark during the period 1985-1995. Using register-based panel data sets from Sweden and Denmark, a picture of the employment assimilation process of immigrants from Norway, Poland, and Turkey is presented. The comparative approach shows that immigrants in Sweden and Denmark experienced similar declines in e

As a consequence of the development of psychiatric care in Sweden, occupational therapists have adapted their roles to changing practice settings. The aim of this study was to investigate the domain of concern of occupational therapists in psychiatric care, operationalized as perceived responsibilities. Furthermore, the relationships of the domain of concern to underlying theories and models, clin

In the light of oil security concerns, the threat of climate change, and a desire to leverage competitive advantage for Sweden and its industries, the Swedish Government has announced a new policy target – the creation of the conditions necessary to break Sweden’s dependence on oil and fossil fuels by 2020. Notably, the Swedish Government stresses national opportunities and highlights two aspects

The arctic fox Alopex lugopus excavates its dens in gravely ridges and hillocks, and creates a local environment quite distinct from the surrounding tundra or heath landscape. In northern Sweden, the vegetation of 18 dens of the arctic fox was investigated, as well as reference areas off the dens but in geologically and topographically similar locations. The species composition showed considerable

Dissociation of 6He on a lead target has been studied at 240 MeV/u. The four-momenta of the two neutrons in coincidence with greek small letter alpha-particles have been measured and used to reconstruct the three-body energy and angular correlations in the final state. For the first time, three-body correlations were included in the analysis of the 6He dissociation data, and compared with calculat

Chromosomal rearrangements involving chromosome bands 12q13-15 are very frequent findings in benign solid tumors, and recently, the primary molecular target for these aberrations was identified as the gene HMGIC. However, mutations in this gene have also been observed in nonneoplastic tissues. In a previous study, we reported breakpoints within HMGIC of synovia affected by osteoarthritis (OA) in t

The effect of preganglionic sympathetic nerve stimulation on mucociliary activity in the rabbit maxillary sinus was investigated in vivo. Response to nerve stimulation was recorded photoelectrically and expressed as a percentage of the basal mucociliary activity prior to stimulation. Nerve stimulation (15 V, 5 ms) for 60 s at 2, 10 and 20 Hz stimulated mucociliary activity, the maximum increase be

The parasympathetically denervated and distended rat urinary bladder was found to have increased fourfold in weight when examined 3 weeks postoperatively. Both in muscularis and mucosa of such a bladder the synthesis of proteins, RNA and DNA was increased severalfold. An increase in the polyamines putrescine, spermidine and spermine was also found; these polyamines are usually linked to protein sy
