BACKGROUND: The association between knee alignment and knee pain in knee osteoarthritis (OA) is unclear. High tibial osteotomy, a treatment option in knee OA, alters load from the affected to the unaffected compartment of the knee by correcting malalignment. This surgical procedure thus offers the possibility to study the cross-sectional and longitudinal association of alignment to pain. The aims
We present a qualitative physical model of the origin of two very brightUV lines of Fe II at 2507-2509 Å, present in high-resolutionspectra of gaseous condensations (blobs) close to the central star ofeta Carinae. The spectra have been obtained with the Hubble SpaceTelescope (HST). The model is based on a type of Bowen mechanism withselective photoexcitation of Fe II by a broad HLyalpha profile,ge
To determine if an inhibition of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH) can counteract the changes in urodynamic parameters and bladder afferent activities induced by intravesical prostaglandin E2 (PGE2 )-instillation, we studied effects of URB937, a peripherally-restricted FAAH inhibitor, on single-unit afferent activity (SAA) during PGE2 -induced bladder overactiv
In a series of 450 patients over 70 years of age with displaced fractures of the femoral neck sustained between 1995 and 1997 treatment was randomised either to internal fixation or replacement. Depending on age and level of activity the latter was either a total hip replacement or a hemiarthroplasty. Patients who were confused or bed-ridden were excluded, as were those with rheumatoid arthritis.
Populärvetenskaplig sammanfattning Morgondagens energi Vind-, och vattenkraft tillsammans med solenergi är de enda energikällorna vi har som inte leder till avfall som ökar växthuseffekt eller avfall som vi inte kan göra oss av (från t ex kärnkraftverk). Men solpanelerna som finns idag för kommersiellt privat bruk ligger på en effektivitet kring 15%. Att utveckla nya molekyler som kan omvanlda solThe aim of the study was to theoretically investigate if a proton coupled electron transfer (PCET) was feasible for a molecular system consisting of a light harvesting complex, ruthenium(tris-2,`2-bipy)2+, with different organic moieties serving as PCET (proton coupled electron transfer) relays. These light harvesting complexes are also sometimes referred to as dyes. By studying the energy levels
The thesis studies the situation within Lund University in relation to the implementation of the European Standards and Guidelines (ESG) developed by The European Association for Quality Assurance in Higher Education (ENQA). The aim of the study is to answer the following research question “How have Lund University implemented the European Standards and Guidelines developed by The European Associa
Nuvarande reglering av säkerhet i lös egendom i Sverige bygger, med undantag för några lagstiftningsåtgärder, på rättspraxis och juridisk doktrin. Även om pantsättning är huvudmetoden för att ställa säkerhet, används i praktiken flera olika typer av säkerhetsrätter då lagstiftaren infört separata registersystem (t.ex. företagshypotek) och då äganderätt i praktiken ofta används som säkerhet (t.ex. Present Swedish law concerning security over movable assets is largely based on case law and legal literature, with some statutory intervention. Although the principal form of security is the possessory pledge, various security devices are used in practice, pursuant to legislative introductions of separate registration systems (e.g. floating charges) and the commercial use of ownership for securit
The Amazon has always been a strategic region because of its rich variety in natural resources. Its global interest is spreading across levels and scales, influenced by the increasing demand for fossil fuels and biodiesel and the threat of climate change. Neoliberal practices continue privatizing and exploiting the Amazon´s resources regardless the Indigenous communities’ interests. These communit
Grooming är ett vedertaget begrepp för det tillvägagångssätt som förövare använder sig av för att ta kontakt med barn, ofta på internet, för att slutligen begå sexuella brott mot barnet. Internetets expansion har på många sätt gett förövare fler tillvägagångssätt att komma i kontakt med barn. En stor andel av barnen i Sverige använder sociala medier, varav många någon gång har blivit kontaktade onGrooming is an established word for the approach that perpetrators are using to contact children, oftentimes over the Internet, ultimately to commit sexual offenses against the child. The expansion of the Internet has in many ways made it easier for perpetrators to approach and contact children. The vast majority of Swedish children use social media, many of whom at some point have been contacted
Behavior and social interactions are key features to determine the phenotype of an organism. Observing behavioral manifestations give insides on a fundamental level of how inner mechanisms work. But how is it possible to predict behavior in a way, such that it can be quantify and analyzed? One traditional strategy is to annotate the behavior by hand. Observing the animals and making notes about th
To stay within our planet’s limits and reach the United Nation’s Sustainable Development Goals, there is an urgent need to rethink our current and dominant systems. This thesis focuses on the food system, in particular, and explores how an overarching turnaround in the way we produce and consume food has the potential to trigger and steer a greater transition towards sustainability. However, this
In this paper, we investigate the long-term post-event stock return performance of companies operating in the IT sector and listed on NASDAQ Stockholm by using 78 mergers and acquisitions deals performed in the 2009 – 2013 period. We apply the event study methodology, focusing on the buy-and-hold abnormal returns approach. Stock return performance is analyzed in comparison to the Swedish general m
The Early Toarcian Oceanic Anoxic Event (T-OAE) represents one of the major alterations of the carbon cycle of the Mesozoic period. Despite being globally recognized, and particularly represented within the Tethys realm, its expression in the sedimentary record is highly variable depending on the studied section, which suggests local environmental factors exert a major control on the resulting lit
Tumor cell death potentially engages with the immune system. However, the efficacy of anti-tumor chemotherapy may be limited by tumor-driven immunosuppression, e.g., through CD25(+) regulatory T cells. We addressed this question in a mouse model of mesothelioma by depleting or reconstituting CD25(+) regulatory T cells in combination with two different chemotherapeutic drugs. We found that the effi
Contributing to the design update phase of the European Spallation Source ESS-scheduled to start operation in 2019-a test beamline is under construction at the BER II research reactor at Helmholtz Zentrum Berlin (HZB). This beamline offers experimental test capabilities of instrument concepts viable for the ESS. The experiments envisaged at this dedicated beamline comprise testing of components as
In the study of insect neuroanatomy, three-dimensional (3D) reconstructions of neurons and neuropils have become a standard technique. As images have to be obtained from whole-mount brain preparations, pigmentation on the brain surface poses a serious challenge to imaging. In insects, this is a major problematic in the first visual neuropil of the optic lobe, the lamina, which is obstructed by the
The aim of this phenomenological study was to explore what role teachers at introductory programmes (SFI-schools) play in the integration of immigrants, how the teachers experience their work and what they feel about the situation in which their students, the immigrants, are. To what extent and in what way do the teachers contribute to facilitating the integration of the immigrant students? The s
This thesis provides an insight into Jamaica’s energy situation and its electricity sector through the barriers that prevent the implementation of renewable energy. In both the energy sector and electricity sub-sector the need to incorporate alternative energy sources, it has revealed, is becoming more apparent with increasing oil prices, widening debt burdens and rising unemployment, among others
