Solvation and ion-pairing properties of the aqueous sulfate anion: explicit versus effective electronic polarization
We assessed the relative merits of two approaches for including polarization effects in classical force fields for the sulfate anion. One of the approaches is the explicit shell model for atomic polarization and the other is an implicit dielectric continuum representation of the electronic polarization, wherein the polarizability density is spatially uniform. Both the solvation and ion association
The fundamentals of Perspective Text Analysis
The major assumption made is that language as a natural system is both self-organising and self-referential. Compared to common syntactic-semantic approaches, the present approach is ecological and builds on the unambiguous identification of textual agents and agencies together with their objectives. Because information transaction cannot be studied without an emphasis on the text producer’s text
Aspects on intra-arterial thrombolysis for lower limb ischemia
Popular Abstract in Swedish Enbart i Sverige drabbas tusentals personer årligen, kvinnor som män, av plötsligt cirkulationsbortfall (akut ischemi) i ett ben till följd av blodpropp i en artär. Tillståndet är akut och innebär ett direkt hot mot såväl liv som lem. Personer som drabbas är ofta äldre, och de har ofta många andra sjukdomar med sig i bagaget. För att rädda benet, och patienten, krävs aBackground: Acute ischemia of the lower limb is a vascular emergency associated with amputation and death. Patients suffering from acute limb ischemia are usually elderly, and multiple comorbidities are often present. Intra-arterial thrombolysis is, perhaps, the most important minimal-invasive treatment option available today. Although uncontrolled hemorrhage is a dreaded complication, it is consi
Impact of crosstalk channel estimation on the DSM performance for DSL networks
The development and assessment of spectrum management methods for the copper access network are usually conducted under the assumption of accurate channel information. Acquiring such information implies, in practice, estimation of the crosstalk coupling functions between the twisted-pair lines in the access network. This type of estimation is not supported or required by current digital subscriber
Search for supersymmetry in pp collisions at root s=7 TeV in final states with missing transverse momentum and b-jets
Results are presented of a search for supersymmetric particles in events with large missing transverse momentum and at least one heavy flavour jet candidate in root s = 7 TeV proton proton collisions. In a data sample corresponding to an integrated luminosity of 35 pb(-1) recorded by the ATLAS experiment at the Large Hadron Collider, no significant excess is observed with respect to the prediction
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb(-1) recorded at the Large Hadron Collider. The anti-k(t) algorithm is used to identify jets, with two jet resolution parameters, R = 0.4 and 0.6. The dominant uncertainty comes from the jet energy s
Search for an excess of events with an identical flavour lepton pair and significant missing transverse momentum in root s=7 TeV proton-proton collisions with the ATLAS detector
Results are presented of a search for particles decaying into final states with significant missing transverse momentum and exactly two identical flavour leptons (e, mu) of opposite charge in root s = 7 TeV collisions at the Large Hadron Collider. This channel is particularly sensitive to supersymmetric particle cascade decays producing flavour correlated lepton pairs. Flavour uncorrelated backgro
The resilience of hegemonic salaryman masculinity: a comparison of three prominent masculinities
It is the aim of this thesis to explore whether salaryman masculinity has lost its status as a hegemonic form of masculinity to otaku masculinity or herbivore masculinity. The thesis makes use of the theoretical framework of hegemonic masculinity as first used by R.W. Connell. In order to assess changes in masculinity, 16 semi-structured in-depth interviews have been conducted with students, both
Interactive voice response - an automated follow-up technique for adolescents discharged from acute psychiatric inpatient care : a randomised controlled trial
Follow-up methods must be easy for young people to handle. We examine Interactive Voice Response (IVR) as a method for collecting self-reported data. Sixty inpatients were recruited from a child and adolescent psychiatric emergency unit in Malmö, Sweden and called every second (N = 30) or every fourth (N = 30) day from discharge until first visit in outpatient care. A pre-recorded voice asked them
Riksbanken och inflationen 1995-2012 - missar Svensson målet?
Vi granskar den uppmärksammade kritik som Lars E O Svensson riktat mot Riksbankens penningpolitik. Vi har en rad invändningar. Svensson har ett för snävt synsätt när han bedömer om Riksbanken har uppfyllt sitt inflationsmål. Hans ekonometriska resultat, vilka utmynnar i slutsatsen att Riksbankens politik gett 38 000 fler arbetslösa per år under 1997−2011, är inte robusta. De vilar på en alltför en
Law in Progress? : A Contextual Study of Norm-Generating Processes - The Example of GMES
Popular AbstractDenna rättssociologiska avhandling studerar "law in progress" genom att undersöka de normbildningsprocesser som framkommer i en interaktion mellan aktörer över tid. Avhandlingen har en empirisk utgångspunkt och illustrerar dessa processer utifrån ett empiriskt exempel, ett Europeiskt "Earth Observation" (EO) initiativ: Global Monitoring for Environment and Security (GMES). AvhandliThis PhD-thesis in Sociology of Law studies ”Law in Progress” by investigating norm-generating processes, which emerge through an interaction between actors over time. The thesis has an empirical approach, thus illustrates these processes through an empirical example, a European “Earth Observation” (EO) initiative: Global Monitoring for Environment and Security (GMES). The main research questions
Neonatal onset atypical hemolytic uremic syndrome successfully treated with eculizumab
Atypical hemolytic uremic syndrome (aHUS) is characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and renal impairment. Neonatal cases are extremely uncommon. Plasma therapy is the first choice therapy in patients with aHUS based on the belief of an underlying complement dysregulation. Alternatively, eculizumab, which targets complement 5, is used to block complement
Proposal for nonlocal electron-hole turnstile in the quantum Hall regime
We present a theory for a mesoscopic turnstile that produces spatially separated streams of electrons and holes along edge states in the quantum Hall regime. For a broad range of frequencies in the nonadiabatic regime the turnstile operation is found to be ideal, producing one electron and one hole per cycle. The accuracy of the turnstile operation is characterized by the fluctuations of the trans
Genome-wide trans-ancestry meta-analysis provides insight into the genetic architecture of type 2 diabetes susceptibility
To further understanding of the genetic basis of type 2 diabetes (T2D) susceptibility, we aggregated published meta-analyses of genome-wide association studies (GWAS), including 26,488 cases and 83,964 controls of European, east Asian, south Asian and Mexican and Mexican American ancestry. We observed a significant excess in the directional consistency of T2D risk alleles across ancestry groups, e
K-ras mutations in sinonasal cancers in relation to wood dust exposure
Background: Cancer in the sinonasal tract is rare, but persons who have been occupationally exposed to wood dust have a substantially increased risk. It has been estimated that approximately 3.6 million workers are exposed to inhalable wood dust in EU. In previous small studies of this cancer, ras mutations were suggested to be related to wood dust exposure, but these studies were too limited to d
Psychometric evaluation of spinal assessment methods to screen for scoliosis in children and adolescents with cerebral palsy.
In cerebral palsy (CP) there is an increased risk of scoliosis. It is important to identify a progressive scoliosis early-on because the results of surgery depend on the magnitude of the curve. The Swedish follow-up program for cerebral palsy (CPUP) includes clinical examinations of the spine. The reliability and validity of the assessment method have not been studied. In this study we evaluate th
Internal Dynamics and Energy Transfer in Dansylated POPAM Dendrimers and Their Eosin Complexes
Internal dynamics of dansylated poly(propyleneamine) dendrimers (POPAM, G1-G4) in solution and excitation energy transfer from dansyls to eosin in POPAM-eosin complexes have been studied by time-resolved fluorescence spectroscopy and molecular dynamics (MD) simulations. Combining the results from fluorescence anisotropy and the MD simulation studies suggests three time domains for the internal dyn
