Numerical and experimental investigation of a gasturbine model combustor with axial swirler

This thesis presents the simulations of and experiments with the so-called CECOST burner. The CECOST burner is a gas turbine model combustor equipped with an axial swirler and placed in a laboratory for the lean premixed turbulent combustion of a range of fuels at atmospheric pressure. The operation with natural gas, methane, hydrogen-enriched methane and syngas from black-liquor gasification was

Classifications of atherosclerotic plaque components with T1 and T2* mapping in 11.7 T MRI

Background and aims: Histopathology is the gold standard for analysis of atherosclerotic plaques but has drawbacks due to the destructive nature of the method. Ex vivo MRI is a non-destructive method to image whole plaques. Our aim was to use quantitative high field ex vivo MRI to classify plaque components, with histology as gold standard.Methods: Surgically resected carotid plaques from 12 patie

The conundrum of asymptomatic carotid stenosis-determinants of decision and evidence

Management of asymptomatic carotid disease continues to challenge medical practice and present evidence is often conflicting. Stroke is a significant burden in Public Health and 11% to 15% appear as first neurologic event associated with asymptomatic carotid stenosis. Randomized trials provided support for Guidelines and Recommendations to intervene on asymptomatic stenosis, but at a known cost of

Ett rum för de ostyrigaste och bullersammaste - eller: Var låg proban? : Del 1

Den första av två artiklar rörande det fängelse, den s k proban, som Lunds universitet hade under den tid lärosätet ägde egen jurisdiktion över anställda och studenter. Denna första del behandlar fenomenet med skol- och universitetsfängelser generellt samt Lunds universitets specifika sådana under 1600- och 1700-talen.

Recent changes in mountain birch forest structure and understory vegetation depend on the seasonal timing of reindeer grazing

Subarctic forest-tundra ecotones dominated by mountain birch (Betula pubescens ssp. czerepanovii) are an important habitat for semi-domestic reindeer Rangifer tarandus. The seasonal timing of reindeer grazing may direct vegetation trajectories in these systems, because in the summer ranges, mountain birches are subjected to browsing, while in the winter ranges, reindeer feed on understorey vegetat

Mörka Neuron och Mobiltelefoner : Dedicerad till en 90-årig man, Arne Brun i Lund

Med denna svenska översikt av våra egna och andra forskares observationer av mörka neuron vid mikrovågs exponering från mobiltelefoner, som lite senkommet tillägnas Arne Brun på hans 90 års-dag, vill vi att hans insatser blir uppmärksammade och inte faller i glömska.Kring 2000 millennium skiftet pågick ett intensivt arbete i Lund med att sammanfatta och bekräfta effekterna av exponering med GSM-90

International Human Rights Law and Time-Space at Sea: A Rhythmanalysis of Prosecuting Search and Rescue

This chapter draws on Lefebvre’s Rhythmanalysis and Production of Space as conceptual, political and metaphorical reservoirs to examine the way in which international protection provisions, as enshrined in international human rights law, are challenged and undermined by current EU migration policies of migration deterrence and containment. In the context of socio-spatial practice, Rhythmanalysis f

Att göra aktivitetsersättning: om målförskjutning och icke-kontakt vid förtidspension för unga

This thesis investigates ‘the doing’ of the Swedish social insurance program Activity Compensation (AC). AC is an example of disability policies in Western welfare states. These policies have two goals: to ensure financial security and to promote social participation. In 2003 AC replaced Early Retirement Pension for persons aged 19 to 29 years and who, for medical reasons, have reduced work capaci

Competing socio-technical narratives in times of grid capacity challenges : the representative case of Sweden

Background: Around the globe the electricity sector is strikingly similar, as regardless of nation it is structured around centralized large-scale power production. However, these centralized systems are currently experiencing operational problems related to climate change, energy security and aging grid infrastructures. In Sweden, the lack of investment and maintenance of the grid have created bo

Extensions of the SEIR model for the analysis of tailored social distancing and tracing approaches to cope with COVID-19

In the context of the COVID-19 pandemic, governments worldwide face the challenge of designing tailored measures of epidemic control to provide reliable health protection while allowing societal and economic activity. In this paper, we propose an extension of the epidemiological SEIR model to enable a detailed analysis of commonly discussed tailored measures of epidemic control—among them group-sp

A database of high-density surface electromyogram signals comprising 65 isometric hand gestures

Control of contemporary, multi-joint prosthetic hands is commonly realized by using electromyographic signals from the muscles remaining after amputation at the forearm level. Although this principle is trying to imitate the natural control structure where muscles control the joints of the hand, in practice, myoelectric control provides only basic hand functions to an amputee using a dexterous pro

Tumor co-expression of progranulin and sortilin as a prognostic biomarker in breast cancer

Background: The growth factor progranulin has been implicated in numerous biological processes such as wound healing, inflammation and progressive tumorigenesis. Both progranulin and its receptor sortilin are known to be highly expressed in subgroups of breast cancer and have been associated with various clinical properties including tamoxifen resistance. Recent data further suggest that progranul

Unga vuxna med nedsatt arbetsförmåga – en beskrivning av trygghetssystemen

Andelen unga som beviljas förtidspension under lång tid har ökat, särskilt de med en psykisk diagnos eller unga med lindrig psykisk ohälsa. Denna form av utanförskap innebär att betydande andelar av en generation av unga människor har liten eller ingen koppling till arbetsmarknaden under en större del av sitt vuxna liv.Bara i Sverige har antalet förtidspensionerade mellan 19-29 år fördubblats unde

Positive symptom phenotypes appear progressively in “EDiPS”, a new animal model of the schizophrenia prodrome

An increase in dopamine (DA) synthesis capacity in the dorsal striatum (DS) during the prodromal stage of schizophrenia becomes more pronounced as patients progress to the full disorder. Understanding this progression is critical to intervening in disease course. We developed an animal model—Enhanced Dopamine in Prodromal Schizophrenia (EDiPS)—which uses a genetic construct to increase DA synthesi

Tumour gene expression signature in primary melanoma predicts long-term outcomes

Adjuvant systemic therapies are now routinely used following resection of stage III melanoma, however accurate prognostic information is needed to better stratify patients. We use differential expression analyses of primary tumours from 204 RNA-sequenced melanomas within a large adjuvant trial, identifying a 121 metastasis-associated gene signature. This signature strongly associated with progress
