M. A. Persinger (2002) claimed that transcranial magnetic stimulation with weak, complex magnetic fields evokes mystical experiences. However, in a double-blind experiment, P. Granqvist, M. Fredrikson, P. Unge, A. Hagenfeldt, S. Valind., et al. (2005) found no effects of field exposure on mystical experiences (N = 89), though a minority of participants reported spontaneous mystical experiences. Fo

Sheep and goats are some of the most important animals in prehistoric Scandinavia. The habitus of the animals was used and transformed into cultural categories. Owing to their important and long-term utility they were ritualised during the pre-Christian periods. The role of these animals and the attitudes towards them in and beyond Norse paganism is discussed with habitus perspectives applied to t

We study the Dirichlet problem for p-harmonic functions (and p-energy minimizers) in bounded domains in proper, pathconnected metric measure spaces equipped with a doubling measure and supporting a Poincare inequality. The Dirichlet problem has previously been solved for Sobolev type boundary data, and we extend this result and solve the problem for all continuous boundary data. We study the regul

To investigate the cause of anomalously bright resonance lines of helium in the Sun, we have studied the magnitude of the enhancements and some proposals made to explain them. Calculations in new semiempirical solar models indicate that the resonance lines of helium are enhanced by factors of 2-5 for He I and between 2 and 9 for He II, depending on the elemental abundances assumed. These enhanceme

Sexually transmitted diseases (STDs) have been shown to increase the Costs Of multiple mating and therefore favor relatively monogamous mating strategies. We examine another way in which STDs can influence mating systems in species in which female choice is important. Because more popular males are more likely to become infected, STDs can counteract any selective pressure that generates strong mat

Bone morphogenetic protein-2 (BMP2) plays a key role in bone formation and maintenance. Studies of polymorphisms within the gene in relation to bone mineral density (BMD) and fracture have been inconsistent. Our aim was to investigate associations between polymorphisms in the BMP2 gene and bone mass, fracture, and quantitative ultrasound (QUS) measures at different stages of skeletal development.

In the present study we have evaluated the knowledge, attitudes and intention to act in relation to HIV/AIDS related issues among Swedish students aged 15–18 years. An intervention group (n = 368) and a comparison group (n = 180) were followed for 2 years between 1989 and 1991. The teachers of the intervention group were obliged to specifically give a continuous and in-depth education while the co

Placental grading was studied prospectively with real-time ultrasound in 654 consecutive pregnancies. The placental maturation was clearly demonstrated in both unselected and hypertensive pregnancies. No differences in placental grading were found between normotensive and hypertensive pregnancies. Fetal outcome was not associated with different placental grades and a grade III placenta was not pre

The pathologic mechanisms of chronic obstructive pulmonary disease (COPD) most certainly involves neutrophil granulocytes, cytotoxic T-cells, macophages and mast cells. The aim of this study was to investigate the relation between the number of mast cells in different compartments in bronchial biopsies of central proximal airways to structural changes, lung function tests and emphysema detected by

Pure Sb0.9V0.9O4 and various preparations with excess of either vanadia or antimony oxide, including mechanical mixtures, have been investigated for propane ammoxidation to acrylonitrile. The catalysts were characterized before and after use in catalysis by various methods, including electron microscopy, infrared spectroscopy and XPS. The catalytic data show that preparations with approximate to S

Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh

The article analyses scholarly works dealing with problems of how Holocaust history has been used in post-war Europe.

Popular Abstract in Swedish Hjärnan är ett energikrävande organ och förbrukar ca 20% av blodets syre trots att den bara utgör 1-2% av kroppsvikten. Mitokondrien är den del av cellen där syre och näringsämnen förbränns till koldioxid och vatten, och mitokondrien kallas ofta för cellens kraftstation. Denna process, den så kallade cellandningen, är kopplad till produktion av den energirika molekylen There is currently no clinically available drug with neuroprotective properties to limit the evolving cell death following e.g. stroke or traumatic brain injury. The mitochondrial permeability transition (mPT) is a potential pathological mechanism causing cell death in the CNS. As the name implies, the mPT is defined by a sudden increase in permeability of the inner mitochondrial membrane, whose n

This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. Also presented is a statistical method for relating the distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. Two

This paper investigates if economic theory can explain variations in piracy behavior between individuals and between countries. It is demonstrated that economic theory explains a notable part of the individual variation in a survey study. Individuals with a low net valuation of an original when a copy is available are more prone to engage in piracy than individuals with a higher valuation. Individ

More than 550 breast adenocarcinomas with clonal chromosomal abnormalities have been reported. Although the aberration pattern is clearly nonrandom, no specific primary or secondary karyotypic abnormality has been identified, and furthermore the chronological order in which the aberrations appear during disease progression is not well known. The high degree of karyotypic complexity in epithelial t
