AIMS: Patients with femoral neck fractures (FNFs) treated with total hip arthroplasty (THA) have an almost ten-fold increased risk of dislocation compared to patients undergoing elective THA. The surgical approach influences the risk of dislocation. To date, the influence of differing head sizes and dual-mobility components (DMCs) on the risk of dislocation has not been well studied. METHODS: In a

Between 1967 and 1972, Swedish futures studies emerged as a distinct political and intellectual endeavor. In this development, the humanities and social sciences played a special role, especially through the idea that human knowledge and knowledge about a “human system” could be brought to bear on societal problems and used to forge a new approach to the future. We focus here on two scholars, hist

Objective:Hemarthrosis after knee trauma often indicates serious joint injury. Few studies have evaluated agreement between clinical examination and findings from magnetic resonance imaging (MRI). We aimed to describe the agreement between acute clinical examination and subacute MRI findings after acute knee trauma with hemarthrosis and the importance of the subspecialty of the examiner.Design:Lon

Teknikutvecklingen inom e-hälsoområdet möjliggör ständigt nya och mer avancerade arbetssätt för att övervaka och vårda patienter digitalt. Vården sker då genom kontinuerlig övervakning av patientens hälsa via digitalt överförda data och kommunikation mellan vårdpersonal och patient där feedback och rekommendationer skräddarsys efter patientens behov och tillstånd. Denna typ av digital vård är ett

Exposure to traumatic stress is a major risk factor for development of neuropsychiatric disorders in a sub-population of individuals, while others remain resilient. The mechanisms and contributing factors differentiating between these phenotypes are still unclear. We hypothesize that inter-individual differences in the microbial composition and function contribute to host resilience or susceptibil

Avhandlingen beskriver och förklarar parlamentarismens utveckling i Västeuropa. Jag definierar parlamentarismen som ett institutionellt arrangemang där endast parlamentet kan hålla regeringen politiskt ansvarig, vilket i det västeuropeiska historiska sammanhanget innebär att statschefen saknar reellt inflytande över regeringens fortlevnad. Genom att samla data från historieforskning om parlamentenThis dissertation describes and explains the development of parliamentarism in Western Europe. Defining parliamentarism as an institutional solution in which the government is politically responsible to parliament only, I use country historiography to map out a tug-of-war between parliament and the head of state over the ability to make governments resign or maintain them in office in 11 West Euro

Ferroelectric HfxZr1–xO2 (HZO) is typically achieved by crystallization of an amorphous thin film via rapid thermal processing (RTP) at time scales of seconds to minutes. For integration on III–V semiconductors, this approach can severely degrade the sensitive HZO/III–V interface. To evaluate whether a reduced thermal budget can improve the interface quality, millisecond duration thermal anneals a

BACKGROUND/AIM: Diagnostic efficacy, defined as the percentage of rectal suction biopsy (RSB) specimens sufficient enough to determine the absence of ganglia cells in Hirschsprung's disease (HD) diagnosis, has been reported to be low, requiring repeated biopsies. The aim was to explore whether RSB diagnostic efficacy was influenced by the child's weight and to ascertain whether RSB efficacy differ

An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage

Antisymmetric, symmetric and standard actuation of acoustofluidic devices were compared in terms of focusability. By imaging the end part of an acoustophoresis separation channel while flowing fluorescent beads through it, we show that beads get more tightly focused by antisymmetric actuation than symmetric and standard actuation at a given electrical input power. This means that antisymmetric act

Premixed ethyl formate + air flames have been investigated at atmospheric pressure and initial temperatures from 298 to 348 K. The burning velocities were determined using the heat flux method for equivalence ratios from 0.6 to 1.5 and were compared with limited data available in the literature and with measurements for the C3H6O2 isomer, methyl acetate, obtained under the same conditions. In ethy

Fluctuations of thermodynamic observables, such as heat and work, contain relevant information on the underlying physical process. These fluctuations are however not taken into account in the traditional laws of thermodynamics. While the second law is extended to fluctuating systems by the celebrated fluctuation theorems, the first law is generally believed to hold even in the presence of fluctuat

Opsins allow us to see. They are G-protein-coupled receptors and bind as ligand retinal, which is bound covalently to a lysine in the seventh transmembrane domain. This makes opsins light-sensitive. The lysine is so conserved that it is used to define a sequence as an opsin and thus phylogenetic opsin reconstructions discard any sequence without it. However, recently, opsins were found that functi
