Arthroplasty for Femoral Neck Fracture. Results of a nationwide implementation.

Hip fractures are devastating for the individual and a substantial economic burden for society. The treatment for displaced femoral neck fracture is a choice between internal fixation, total hip arthroplasty and hemiarthroplasty. As a result of several randomized trials, the treatment has shifted in Sweden from mostly internal fixation towards arthroplasties. There have been concerns about long-te

Effects of momentum-dependent self-energy in the electronic structure of correlated materials

We study how the k dependence in the self-energy affects the quasiparticle band structure and one-particle spectral functions. It is known that, in electron-gas-like materials, the self-energy depends significantly on k and there is a strong cancellation between the k dependence and the energy dependence of the self-energy. Analysis of the GW self-energy reveals that, even in correlated materials

Energy Security and Climate Change Mitigation as Combined Areas of Analysis in Contemporary Research

Climate change mitigation and energy security are partly interacting areas that both present future challenges. The extensive research underway within these areas is mainly conducted in separate research communities, although there are some integrative efforts. This paper examines the breadth and heterogeneity involved in treating energy security and climate change mitigation as a combined researc

"Orden med krona och fågelsång" : om språk och stil, genre och drama i förslaget

Det nya handboksförslaget granskas med avseende på språk och stil och med avseende på strukturen i gudstjänsten. Flera kritiska synpunkter på språk och stil ges, och placeringen av syndabekännelsen i gudstjänstens inledning liksom placeringen av förbönen mellan predikan och nattvard kritiseras, detta med utgångspunkt från hermeneutiska insikter, och från dramaturgisk analys.

The influence of porous silicon on axonal outgrowth in vitro.

Axonal outgrowth on smooth and porous silicon surfaces was studied in organ culture. The pore size of the silicon substrata varied between 100 and 1500 nm. We found that axons preferred to grow and elongate on porous silicon surfaces only when pores of (150-500 nm) are available.

Testing for Rationality, Separability and Efficiency

Popular Abstract in Swedish Denna avhandling syftar till att föreslå, utvärdera och applicera testprocedurer för rationalitet, svag separabilitet och effektivitet. Främst behandlas icke-parametriska så kallade ’revealed preference’ procedurer, vilka har fördelen att de, till skillnad från den parametriska ansatsen, inte behöver anslå någon funktionell form för nyttofunktionen. En majoritet av de tThis thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. This approach has the advantage of not having to stipulate any functional form for the utility function, unlike the parametric approach which relies on finding a suitable functional form for the utility functio

Components of uncertainty in species distribution analysis: a case study of the Great Grey Shrike

Sophisticated statistical analyses are common in ecological research, particularly in species distribution modeling. The effects of sometimes arbitrary decisions during the modeling procedure on the final outcome are difficult to assess, and to date are largely unexplored. We conducted an analysis quantifying the contribution of uncertainty in each step during the model-building sequence to variat

Understory succession in post-agricultural oak forests: Habitat fragmentation affects forest specialists and generalists differently

The herbaceous understory forms the richest stratum in temperate broadleaved forests in terms of plant diversity. Understanding the process of understory succession is thus of critical importance for the development of management guidelines for biodiversity restoration in post-agricultural plantation forests. We studied effects of stand age, forest fragmentation, and soil and canopy conditions on

Expression of ATF3 and axonal outgrowth are impaired after delayed nerve repair

Background: A delay in surgical nerve repair results in impaired nerve function in humans, but mechanisms behind the weakened nerve regeneration are not known. Activating transcription factor 3 (ATF3) increases the intrinsic growth state of injured neurons early after injury, but the role of long-term changes and their relation to axonal outgrowth after a delayed nerve repair are not well understo

TFEB-mediated autophagy rescues midbrain dopamine neurons from α-synuclein toxicity.

The aggregation of α-synuclein plays a major role in Parkinson disease (PD) pathogenesis. Recent evidence suggests that defects in the autophagy-mediated clearance of α-synuclein contribute to the progressive loss of nigral dopamine neurons. Using an in vivo model of α-synuclein toxicity, we show that the PD-like neurodegenerative changes induced by excess cellular levels of α-synuclein in nigral

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at=8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1 fb(-1) of proton-proton collision data at = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via or , where denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final st

MYC inhibition induces metabolic changes leading to accumulation of lipid droplets in tumor cells

The MYC genes are the most frequently activated oncogenes in human tumors and are hence attractive therapeutic targets. MYCN amplification leads to poor clinical outcome in childhood neuroblastoma, yet strategies to modulate the function of MYCN do not exist. Here we show that 10058-F4, a characterized c-MYC/Max inhibitor, also targets the MYCN/Max interaction, leading to cell cycle arrest, apopto

The great dichotomy of the Solar System: Small terrestrial embryos and massive giant planet cores

The basic structure of the Solar System is set by the presence of low-mass terrestrial planets in its inner part and giant planets in its outer part. This is the result of the formation of a system of multiple embryos with approximately the mass of Mars in the inner disk and of a few multi-Earth-mass cores in the outer disk, within the lifetime of the gaseous component of the protoplanetary disk.

The influence of calibration method and eye physiology on eyetracking data quality

Abstract in UndeterminedRecording eye movement data with high quality is often a prerequisite for producing valid and replicable results and for drawing well-founded conclusions about the oculomotor system. Today, many aspects of data quality are often informally discussed among researchers but are very seldom measured, quantified, and reported. Here we systematically investigated how the calibrat

Moisture transport properties of lime-hemp concrete determined over the complete moisture range

To determine the durability of a lime-hemp concrete (LHC) wall and its resistance to driving rain, moisture conditions inside the wall have to be modelled. As model input, moisture transport properties were determined. Two LHC mixes were studied. Cup tests provided moisture diffusivity results at relative humidity (RH) values up to 95%. Capillary water uptake tests provided results for the interva
