The Archean basement in the northeastern part of the Kaapvaal craton is intruded by a large number of mafic dykes, defining three major dyke swarms, which collectively appear to fan out from the Bushveld Complex. Herein we present U-Pb baddeleyite ages for two of these dyke swarms, the northwest trending Badplaas Dyke Swarm and the east-west trending Rykoppies Dyke Swarm, and infer their correlati
Familial adenomatous polyposis (FAP) is caused by germline mutations in the adenomatous polyposis coli (APC) gene. Two promoters, 1A and 1B, have been recognized in APC, and 1B is thought to have a minor role in the regulation of the gene. We have identified a novel deletion encompassing half of this promoter in the largest family (Family 1) of the Swedish Polyposis Registry. The mutation leads to
Palaeomagnetic and geochronological studies on mafic rocks in the Lake Ladoga region in South Russian Karelia provide a new, reliably dated Mesoproterozoic key paleopole for the East European Craton (Baltica). U-Pb dating on baddeleyite gives a crystallisation age of 1452 +/- 12 Ma for one of the studied dolerite dykes. A mean palaeomagnetic pole for the Mesoproterozoic dolerite dykes. Valaam sill
This study shows the result of a simulation of a proposed kinetic reaction scheme of high-concentration (5000 ppm NO) and high-temperature (570–800 K) selective catalytic reduction of NO with NH3 on a commercial vanadia based catalyst at a system pressure of 2.2 bar. The simulations are performed with COMSOL Multiphysics ver. 5.1. Experimental data from a catalytic flow reactor can be nicely fitte
Anew search signature for excited leptons is explored. Excited muons are sought in the channel pp → μμ∗→ μμ jet jet, assuming both the production and decay occur via a contact interaction. The analysis is based on 20.3 fb-1 of pp collision data at a centre-of-mass energy of s = 8 TeV taken with the ATLAS detector at the large hadron collider. No evidence of excited muons is found, and limits are s
A search has been made for supersymmetry in a final state containing two photons and missing transverse momentum using the ATLAS detector at the Large Hadron Collider. The search makes use of 3.2fb-1 of proton-proton collision data collected at a centre-of-mass energy of 13 TeV in 2015. Using a combination of data-driven and Monte-Carlo-based approaches, the Standard Model background is estimated
The results of a search for the top squark, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, jets, and missing transverse momentum are reported. The search uses the 2015 LHC pp collision data at a center-of-mass energy of s=13 TeV recorded by the ATLAS detector and corresponding to an integrated luminosity of 3.2 fb-1. The analysis targets two types
Svår fetma är ett svårbehandlat tillstånd och hittills har fetmakirurgi visat sig vara den metod som ger den största och mest beständiga viktminskningen över längre tid. Fetmakirurgi har tidigare endast erbjudits vuxna både i Sverige och i andra länder. Under senare år har fetmakirurgi börjat prövas som ett behandlingsalternativ till ungdomar med svår fetma där annan behandling inte har gett tillrBariatric surgery is tried out as a new treatment option for adolescents with severe obesity. Little is known about outcomes in mental health in adolescents who undergo weight loss surgery.The 3 studies in this thesis assess mental health in adolescents before, and after 4 months, 1 year and 2 years after undergoing gastric bypass. The studies are part of the Swedish national AMOS study and all ad
Annually laminated sediments of Lake Woserin in north-eastern Germany are investigated using sedimentological and palynological methods. They facilitate high-resolution reconstruction of environmental and land-use change during ca. 7000–4000 cal. BP. Between 6100 and 5800 cal. BP, changes in woodland composition and structure are evident which coincide with a change in subsistence strategy, that i
Objectives: To examine whether the mix of community and institutional long-term care (ILTC) for people with dementia (PwD) in Europe could be improved; assess the economic consequences of providing alternative services for particular groups of ILTC entrants and explore the transnational application of the ‘Balance of Care’ (BoC) approach. Method: A BoC study was undertaken in Estonia, Finland, Fra
Background: There is an urgent need to improve patient safety in the area of medication treatment among the elderly. The aim of this study was to explore which improvement needs and strengths, relating to medication safety, arise from a multi-professional intervention in primary care and further to describe and follow up on the agreements for change that were established within the intervention. M
ABSTRACTAs a part of a democratic demand for transparency in urban development processes it is important that design professionals hold the ability to scrutinise their own work process, and at certain stages let go of predefined ideas of future realities. This work revolves around how design professionals perceive options for design in such situations. A basic assumption in this work is that a des
IntroductionGovernment and public agencies in Sweden have promoted the expansion of eHealth. The strategy behind many of the eHealth services is to increase quality of care, enhance efficiency, patient empowerment and patient safety. Patient online access to their electronic health record (EHR) is one of the most important civic eHealth services. By 2017, all patients in Sweden will be able to acc
A reliable assessment of glomerular filtration rate (GFR) is of paramount importance in clinical practice as well as epidemiological and clinical research settings. It is recommended by Kidney Disease: Improving Global Outcomes guidelines in specific populations (anorectic, cirrhotic, obese, renal and non-renal transplant patients) where estimation equations are unreliable. Measured GFR is the onl
A search for dark matter (DM) particles produced in association with a hadronically decaying vector boson is performed using pp collision data at a centre-of-mass energy of s=13 TeV corresponding to an integrated luminosity of 36.1 fb−1, recorded by the ATLAS detector at the Large Hadron Collider. This analysis improves on previous searches for processes with hadronic decays of W and Z bosons in a
A 2-year-old boy underwent an uneventful transanal endorectal pull-through for Hirschsprung's disease. Postoperatively he suffered from pneumaturia which prompted surgical evaluation. He was found to have a rectum to seminal vesicle fistula. He was re-operated closing the fistula through an anterior transperineal approach with a successful operative outcome.
To prospectively study the prevalence of Lyme arthritis, 100 consecutive patients referred to a rheumatology out-patient clinic and 115 patients with a classified rheumatological disease were included. Individuals seropositive for antibody against the Borrelia burgdorferi sensu lato complex were examined for clinical signs or a history of Lyme borreliosis. Positive titres against B. burgdorferi s.
