Impacts of future weather data typology on building energy performance – Investigating long-term patterns of climate change and extreme weather conditions

Patterns of future climate and expected extreme conditions are pushing design limits as recognition of climate change and its implication for the built environment increases. There are a number of ways of estimating future climate projections and creating weather files. Obtaining adequate representation of long-term patterns of climate change and extreme conditions is, however, challenging. This w

Pushing diffusion MRI towards new dimensions

Diffusion-MRI techniques allow the non-invasive investigation of microstructural changes in living tissues. However, a detailed interpretation of the data is complicated by the fact that multiple microscopic environments with varying diffusion properties all contribute to the measured signal. To address this problem, we adapt strategies from solid-state NMR spectroscopy and magnetic resonance of p

Transition governance for energy efficiency - Insights from a systematic review of Swedish policy evaluation practices

Background: The transition towards a more sustainable energy system is urgent for addressing global environmental and social challenges, and will require transformative changes including improved energy efficiency in the built environment. To reach identified efficiency potentials, various policy instruments have been introduced but their effects are often unclear. In this paper, we argue that the

Novel oligodendroglial alpha synuclein viral vector models of multiple system atrophy : studies in rodents and nonhuman primates

Multiple system atrophy (MSA) is a horrible and unrelenting neurodegenerative disorder with an uncertain etiology and pathophysiology. MSA is a unique proteinopathy in which alpha-synuclein (α-syn) accumulates preferentially in oligodendroglia rather than neurons. Glial cytoplasmic inclusions (GCIs) of α-syn are thought to elicit changes in oligodendrocyte function, such as reduced neurotrophic su

Fulminant Versus Acute Nonfulminant Myocarditis in Patients With Left Ventricular Systolic Dysfunction

Background: Fulminant myocarditis (FM) is a form of acute myocarditis characterized by severe left ventricular systolic dysfunction requiring inotropes and/or mechanical circulatory support. A single-center study found that a patient with FM had better outcomes than those with acute nonfulminant myocarditis (NFM) presenting with left ventricular systolic dysfunction, but otherwise hemodynamically

Assessing tobacco use in Swedish young adults from self-report and urinary cotinine : A validation study using the BAMSE birth cohort

Objectives Studies on health effects of tobacco often rely on self-reported exposure data, which is subjective and can lead to misclassification. The aim of this study was to describe the prevalence of cigarette smoking, snus and e-cigarette use, as well as to validate self-reported tobacco use among young adults in Sweden. Method Participants of a population-based Swedish cohort (n=3052), aged 22

Health impact assessment of road traffic noise exposure based on different densification scenarios in Malmö, Sweden

While urbanization provides many opportunities to those arriving in thriving urban areas, a greater number of residents necessitates the expansion of housing and infrastructure. This is often achieved through densification, which can lead to increased noise, particularly through increased road traffic. A key challenge of promoting healthy urban planning is to understand potential health effects, e

Coregistered histology sections with diffusion tensor imaging data at 200 µm resolution in meningioma tumors

A significant problem in diffusion MRI (dMRI) is the lack of understanding regarding which microstructural features account for the variability in the diffusion tensor imaging (DTI) parameters observed in meningioma tumors. A common assumption is that mean diffusivity (MD) and fractional anisotropy (FA) from DTI are inversely proportional to cell density and proportional to tissue anisotropy, resp

Early postoperative 18F-FET PET/MRI for pediatric brain and spinal cord tumors

Complete resection is the treatment of choice for most pediatric brain tumors, but early postoperative MRI for detection of residual tumor may be misleading because of MRI signal changes caused by the operation. PET imaging with amino acid tracers in adults increases the diagnostic accuracy for brain tumors, but the literature in pediatric neurooncology is limited. A hybrid PET/MRI system is highl

Thermoregulatory costs of the innate immune response are modulated by winter food availability in a small passerine

In winter, a challenge to the immune system could pose a major energetic trade-off for small endotherms, whereby increasing body temperature (Tb; i.e. eliciting fever) may be beneficial to fight off invading pathogens yet incur a cost for vital energy-saving mechanisms. Having previously shown that the availability and acquisition of energy, through manipulation of food predictability, influences

Epidemiological register studies on pain - etiology, treatment, and mental health

Pain is common in life and can be caused by trauma or underlying disease and is mostly temporary, but for some the pain can develop into a chronic pain condition. Pain leads to individual suffering as well as negative impact on the wider society. Especially since pain can start early in life and affect large parts of it. The aim of this thesis was to identify potential risk factors for chronic and

Life-cycle assessment of yeast-based single-cell protein production with oat processing side-stream

Production of fish meal and plant-based feed proteins continues to increase to meet the growing demand for seafood, leading to impacts on marine and terrestrial ecosystems. Microbial proteins such as single-cell proteins (SCPs) have been introduced as feed alternatives since they can replace current fish feed ingredients, e.g., soybean, which are associated with negative environmental impacts. Mic

Associations between the APOE-ε2 and APOE-ε4 alleles with resistance and resilience against Alzheimer's disease pathology

BACKGROUND: To examine associations between the APOE-ε2 and APOE-ε4 alleles and core Alzheimer's disease (AD) pathological hallmarks as measured by amyloid-β (Aβ) and tau PET in older individuals without dementia. METHOD: We analyzed data from 462 ADNI participants without dementia who underwent Aβ ([18 F]florbetapir or [18 F]florbetaben) and tau ([18 F]flortaucipir) PET, structural MRI and cognit

Global maps of soil temperature

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and biocl

Wildfire impacts on the carbon budget of a managed Nordic boreal forest

Wildfire is one of the most important disturbances affecting boreal forests. Most previous research on boreal forest fires has occurred in North American forests which have different fire regimes, tree species and are less intensively managed than their Eurasian counterparts. Recent extreme fire years have highlighted the vulnerability of the Nordic boreal forest to climatic shifts that are increa

Methodological uncertainties in estimating carbon storage in temperate forests and grasslands

Carbon sequestration is an essential ecosystem service (ES) for climate change mitigation. For reasons of simplicity this ES is often quantified considering carbon storage in four carbon pools: aboveground biomass, belowground biomass, dead organic matter and soil organic carbon. Indicators of these four pools are estimated by modelling, reference values, or field methods and data processing of di

Discordance Between Creatinine-Based and Cystatin C–Based Estimated GFR : Interpretation According to Performance Compared to Measured GFR

Rationale & Objective: Use of cystatin C in addition to creatinine to estimate glomerular filtration rate (estimated glomerular filtration rate based on cystatin C [eGFRcys] and estimated glomerular filtration rate based on creatinine [eGFRcr], respectively) is increasing. When eGFRcr and eGFRcys are discordant, it is not known which is more accurate, leading to uncertainty in clinical decisio

Moving in the right direction : an analysis of sustainability challenges of Emmaus Fredriksdal (a second-hand business within a solidarity movement)

The thesis studies the main sustainability challenges of Emmaus Fredriksdal, which is one of the groups of Emmaus International in Sweden. The organisation has its origin in a solidarity movement, which started in Paris after World War II with the purpose to provide support to the homeless and needy. Emmaus Fredriksdal is a young non-profit organisation in change that is becoming particularly acti

Developing a Decision Support Tool for Increased Warehouse Picking Efficiency

Problembeskrivning: Lagerverksamhet utgör en central del i att uppnå en konkurrenskraftig försörjningskedja och betraktas som direkt avgörande för ett företags framgång, eller utebliven sådan. Det är en dyr verksamhet, och en stor del av ett företags totala logistikkostnader kan hänvisas direkt till lagret. Följaktligen finns det ett behov för lager att prestera jämnare, snabbare och mer precist. Problem description: Warehousing is central in order to achieve a competitive supply chain, and considered essential for the success, or failure, of businesses today. In general, warehouses account for a large share of the company logistics costs. Consequently, there is a need for warehouses to operate smoother, faster and more accurate. Within warehousing, the most labor-intensive and costly ware

Finns det ett behov av en särreglering av hedersrelaterade våldsbrott?

I Sverige förekommer fortfarande problem med hedersrelaterade våldsbrott. År 2016 var en tredjedel av alla mord som begicks mot kvinnor hedersrelaterade. Många röster har höjts för att en straffskärpning bör ske på området. Mitt syfte med uppsatsen har varit att utreda om det finns ett behov att införa en särreglering vad gäller våldsbrott med heder som motiv i straffskärpande syfte. Följande fråg
