Inom psykologi och etnologi studeras företeelser ur perspektiv som återfinns hos den enskilda individen samt i det lokala eller sociala sammanhanget. I studien har olika styrmedel bedömts från ett etnologiskt och psykologiskt perspektiv. Studien har därvid inneburit nya arbetsmetoder – i varken psykologi eller etnologi brukar man arbeta med att förutsäga hur olika medel (t.ex. styrmedel) påverkar

Highest resolution imaging in astronomy is achieved by interferometry, connecting telescopes over increasingly longer distances and at successively shorter wavelengths. Here, we present the first diffraction-limited images in visual light, produced by an array of independent optical telescopes, connected electronically only, with no optical links between them. With an array of small telescopes, se

Laminar burning velocities of acetone + air mixtures at initial gas mixture temperatures of 298, 318, 338 and 358 K are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm, and laminar burning velocities were determined using the heat flux method, at conditions where the net heat loss from the flame to the burner is zero. The overall accuracy of the burning velocit

The annealing-induced formation of (Mn, Ga)As nanocrystals in (Ga, Mn)As/GaAs superlattices was studied by x-ray diffraction, transmission electron microscopy and magnetometry. The superlattice structures with 50 Å thick (Ga, Mn)As layers separated by 25, 50 and 100 Å thick GaAs spacers were grown by molecular beam epitaxy at low temperature (250 ° C), and then annealed at high temperatures of 400

Background: To investigate hand bone loss (HBL) measured by digital X-ray radiogrammetry (DXR) in patients with early rheumatoid arthritis (RA) receiving different treatment regimens, and to evaluate if DXR change rates during the first 12 months correlate with radiological damage after 24 months. Methods: From the total SWEFOT trial population, 159 patients had hand radiographs correctly timed an

The aim of this study was to investigate the possibility to produce novel powder materials based on chemically modified starch granule stabilized Pickering oil-in-water (O/W) emulsions. This study also investigated the effect of partial starch gelatinization in situ, dispersed phase type (two oil types with different melting points), freezing method and thawing, and freeze-drying and rehydrating o

Lipid compositions with the ability to self-assemble into biocompatible nano- and mesostructured functional materials have many potential uses in modem medicine. By using two-component lipid systems, it is possible to tune the structure formation and related functional properties, e.g., the encapsulation and extended release of small molecules and peptides, by simply varying the ratio of the lipid

The phenomenon of water vapour sorption by anhydrous C(3)A polymorphs both in the absence and in the presence of CaSO4 center dot 0.5 H2O was studied utilising dynamic and static sorption methods. It was found that orthorhombic C(3)A starts to sorb water at 55% relative humidity (RH) and cubic C(3)A at 80% RH. Also, C(3)Ao sorbs a higher amount of water which is predominantly physically bound, whe

The chapter reviews evidence for the bodily mimesis hypothesis, which states that the evolution of language was preceded by an adaptation for improved volitional control of the body, giving our ancestors advantages in the domains of imitation, empathy, and gestural communication. Much of this evidence is also shared by other gesture-first theories of language origins, but they face the problem of

The measurement of missing transverse momentum in the ATLAS detector, described in this paper, makes use of the full event reconstruction and a calibration based on reconstructed physics objects. The performance of the missing transverse momentum reconstruction is evaluated using data collected in pp collisions at a centre-of-mass energy of 7 TeV in 2010. Minimum bias events and events with jets o

The location of Mn atoms in the MBE-grown layers of Ga1-xMnxAs is correlated with all important physical properties of the final material, therefore, it is the subject of many studies. It is known that in the as-grown MBE samples the Mn atoms occupy substitutional and interstitial positions but the proportion between these sites is not easy to find. A powerful tool for this kind of study is XAS as

Popular Abstract in Swedish Enligt Världshälsoorganisationen (WHO) är en god hälsa ett "tillstånd av fullständigt fysiskt, socialt och mentalt välbefinnande, och inte enbart avsaknad av sjukdom eller funktionshinder". Vår hälsa påverkas under hela vår levnad av en mängd faktorer såsom exempelvis våra gener, biologiska faktorer, sociodemografiska faktorer, beteendefaktorer och livsstil samt miljöfaAbstract: The complexity of health relates to the interplay between numerous factors, e.g., biological and genetic factors, sociodemographic factors, life-style, environmental factors as well as health care services, all possibly acting throughout the life-course. While earlier health theories mainly have focused on adult life style as causes of adult ill-health, life-course research has in recent

Stem cells have qualities that clearly distinguish them from all other cells. Capabilities like self-renewal, differentiation and migration make them truly powerful. This thesis deals with different aspects of stem/progenitor cells in relation to cancer. Certain types of neural progenitor cells (NPCs) have been shown to possess a potential of tracking glioma cells in the brain. This makes them pot

Cohesive zone modeling at finite displacements and crack openings are discussed and evaluated in relation to the fundamental principles provided by thermodynamic consistency, balance of angular momentum and material frame indifference. It is shown that among the existing prototype cohesive zone models within the classical cohesive zone framework, only fully isotropic elastic models or fully isotro

Kiselalger finns över nästan hela jorden och står för en stor del av jordens samlade fotosyntes. Deras kloroplaster härstammar från rödalger, men resten av deras celler kommer från andra håll. Kiselalgerna har många gener vilkas närmaste släktingar återfinns hos djur, svampar, grönalger eller olika bakterier.

This article article examines to what extent and how the EU ETS has influenced the climate strategies of two Nordic pulp and paper companies: Swedish SCA and Norwegian Norske Skog. Rising electricity prices are perceived to be the greatest effect of the scheme. The EU ETS has served to reinforce commitments to improve energy efficiency and reduce CO2 emissions in both companies studied. Procedures
