Polymer/silica composite films, stable to calcination, were produced using catanionic surfactant mixtures (hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS)) and polymers (polyethylenimine (PEI) or polyacrylamide (PAAm)) at the air/water interface. Film formation processes were probed by time-resolved neutron reflectivity measurements. Grazing incidence X-ray diffraction (

BACKGROUND: Glutamic acid decarboxylase antibodies (GADA) and tyrosine phosphatase antibodies (islet antigen-2 antibodies; IA-2A) are used in clinical practise to identify type 1 diabetes. METHODS: GADA and IA-2A were measured with RSR-ELISA kits in samples from 76 newly diagnosed type 1 diabetic children and 120 healthy controls. The aim was to evaluate performance of RSR-ELISA kits for GADA and

Background: Naloxone, an opioid receptor antagonist, is used as a pharmacological tool to detect tonic endogenous activation of opioid receptors in experimental pain models. We describe a pharmacokinetic model linking naloxone pharmacokinetics to its main metabolite after high-dose naloxone infusion. Methods: Eight healthy volunteers received a three-stage stepwise high-dose i.v. naloxone infusion

Background: Most validations of paediatric glomerular filtration rate (GFR) estimating equations using standardized creatinine (CR) and cystatin C (CYS) assays have comprised relatively small cohorts, which makes accuracy across subgroups of GFR, age, body mass index (BMI) and gender uncertain. To overcome this, a large cohort of children referred for GFR determination has been established from se

Background: Manganese (Mn) is an essential element but at excessive levels, it is neurotoxic. Even a moderate increase in Mn has been suggested to interfere with neurodevelopment in children. Genetics influencing Mn concentrations and toxicity is unclear. Objective: We assessed, in a cross-sectional study, whether common single-nucleotide polymorphisms in the Mn transporters SLC39A8 (influx) and S

Safe long-term storage of spent nuclear fuel (SNF) is one of the main issues in the field of nuclear safety. Burn-up credit application in criticality analysis of SNF reduces conservatism of usually used fresh fuel assumption and implies a positive economic impact for the SNF storage. Criticality calculations of spent nuclear fuel in the CONSTOR® RBMK-1500/M2 cask were performed using pre-generat

The aim of this thesis is to analyze the effects of both marketization and the corona pandemic on elderly care work in Swedish nursing homes. The study analyses stories, lived experiences and emotions of eight care workers by conducting qualitative semi-structured interviews. Further, I shed light on how these care workers see, feel and handle care users’ needs and organizational challenges in the

Vindkraftverk är ett av samhällets främsta verktyg för en miljövänlig energiproduktion. Den konventionella designen av bladen är emellertid i stort sett oförändrad. Triblade är ny typ av design som har potentialen att revolutionera marknaden. Genom att använda en fackverksstruktur öppnar man för möjligheten att utforska andra materialval än de konventionella kol- och glasfibermaterial som anväIn the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade

In a globalized world, schools are becoming more diverse. Research has shown that feelings of belonging are important for the success of migrants in school. Mostly quantitative research has been carried out, however, and it has shown a relationship between belonging and educational achievement, academic motivation, and health-related issues. For this thesis, I use previous research as a stepping s

The present thesis investigates motion-emotion metaphors in Estonian and compares them cross-linguistically with Finnish, English and Swedish. Motion-emotion metaphors (e.g. I fell into depression) are expression types that denote affective responses, which imply conspicuous bodily changes, using motion verbs and other linguistic expressions that typically express actual motion. Metaphor has been

Med het avgasrecirkulering kan gasturbiners bränsleförbrukning minska med 15 %. Detta revolutionerande resultat har kommit fram genom en studie gjord som ett examensarbete på Siemens Industrial Turbomachinery AB. Jordens klimatförändring är vår tids största utmaning. Med mer förnybar elpoduktion, som till exempel sol- och vindkraft, ökar också behovet av snabbt reglerad balanskraft. Alltså kraft By recirculating exhaust gases to the gas turbine inlet a temperature rise and hence, a density reduction, is achieved at the compressor inlet. For a constant volume flow this results in a reduced mass flow, ultimately affecting the temperature of the flame, and the emissions, at part load. This study is conducted by creating a model of the Siemens twin shaft gas turbine SGT-750 in the software IP

Inequality and the risk of poverty in Icelandic society have been in the debate since the economic crisis in 2008. The family policy is criticised by academics for a lack of economic support for individuals with dependent children both in the form of child benefits and low payments during parental leave. The purpose of this thesis is to analyse how economic support for families of cohabitating par

CFD simulations of direct gas injection, especially in large dual-fuel engines, can be expensive both regarding time and computational power. The nozzle area needs to be resolved with a fine mesh to capture all phenomena and for a full engine model this results in a large amount of cells. A method using a Lagrangian Particle Tracking (LPT) approach was developed to handle gas injection by injectin

This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-w

The humanitarian interventions that occurred in the late 90’s gave rise to a variety of discussions and caused divergence between the world nations. Following this the Canadian government formed The International Commission on Intervention and State Sovereignty (ICISS) which later in December 2001 introduced The Responsibility to Protect (R2P). The presented proposal by the commission comprises se

Syftet med denna kvalitativa studie var att få en fördjupad förståelse av hur det är att ha hypotyreos. Datainsamlingen gjordes genom semistrukturerade intervjuer och för tolkningen användes tematisk analys. Sex deltagare intervjuades med lindriga till mycket svåra symtom. Studiens resultat har funnit områden där vårdens bemötande brister gentemot sköldkörtelsjuka med kvarstående symtom. Råd baserThe goal of this study was to reach a deeper understandig of what it is like to have hypothyroidism. Data was collected through semi-structured interviews and interpreted using thematic analysis. Six participants with minor and severe symtoms were interviewed . The study found areas in which professional health care, recieved by patients with hypothyroidism who are experiencing residual symtoms, w

I den aktuella studien undersöktes barns förmåga att med hjälp av verktyg använda tidigare kunskaper för att lösa en ny uppgift, genom en så kallad analog överföring. Uppgiften ställde krav barnets förmåga att bortse från vilseledande visuell information, till förmån för verktygets funktionalitet. 90 barn mellan 24 och 55 månader rekryterades från sju förskoleverksamheter i en svensk kommun. BarneChildren’s ability to access previous knowledge and use tools when solving a novel analogical task was examined. When confronted with the task, the children had to ignore misleading visual tool information and attend to its functionality. 90 children between 24 and 55 months from seven preschools were recruited. The study’s design was quasi-experimental and factorial, and the children were confron
