BackgroundEmerging evidence suggests that prenatal or early-life exposures to environmental contaminants may contribute to an increased risk of asthma and allergies in children. We aimed to the explore associations of prenatal exposures to a large set of environmental chemical contaminants with asthma and eczema in school-age children. MethodsWe studied 1024 mother-child pairs from Greenland and U
A three dimensional cohesive zone model for perpendicular to grain wood fracture analysis is derived within the framework of plasticity theory and implemented for numerical calculations by the finite element method. The criterion used for strain instability and localization to a fracture plane is according to the orthotropic Tsai-Wu criterion accounting for all six stress components. The after loc
Thymidine kinase 2 (TK2) deficiency in humans causes mitochondrial DNA (mtDNA) depletion syndrome. To study the molecular mechanisms underlying the disease and search for treatment options, we previously generated and described a TK2 deficient mouse strain (TK2(-/-)) that progressively loses its mtDNA. The TK2(-/-) mouse model displays symptoms similar to humans harboring TK2 deficient infantile f
This thesis examines how Iceland and Sweden justify and institutionalise gold-plating mitigation strategies in the transposition of EU and EEA law. Gold-plating, where national implementation exceeds EU minimum requirements, is often framed as a regulatory problem. At the same time, gold-plating mitigation strategies may constrain national discretion and reflect underlying political, ideological,
In this thesis we performed a pooled cohort study to investigate the role of radiomics in head and neck cancer prognosis. The aim was to investigate prognostic value for overall survival and cancer recurrence of radiomics combined with previously studied demographic and clinical risk factors. Radiomics features were extracted from the gross tumor volume on a computed tomography captured prior to r
The 2011 UN Guiding Principles on Business and Human Rights (UNGPs) introduced human rights due diligence (HRDD) as a societal expectation to businesses to implement a new kind of due diligence risk management process to ‘know and show’ they respect human rights. Ten years later, mandatory human rights due diligence (mHRDD) legislation imposing a legal duty to carry out HRDD has become mainstream
Stickiness of different food products on surfaces can occur naturally during food filling in Tetra Recart form- and seal machines. The aim of this thesis was to develop a model and an adhesion test method for determining and understanding this stickiness. More specifically for the food products whole peeled tomatoes, sliced mushrooms, mandarin chops and peach halves on stainless-steel. Additionall
Using reforestation for climate change mitigation is complex due to the multiple impacts forest has on climate. This study analyses the effectiveness in using reforestation on pasture in Scania (south Sweden) as a tool for climate mitigation. The potential carbon storage in biomass and the impact on land surface properties that determine the absorption of radiation (albedo) was assessed. To answer
How do low carbon transitions in developing economies differ from decarbonization of developed economies? Which specific challenges face developing economies? This thesis discusses the literature on low carbon technology transfers, climate finance and carbon lock-in in developing economies and applies these concepts to the Indian case. The carbon intensity of energy supply is analyzed using the en
This thesis investigated the potential of using reactive power compensation to solve overvoltage issues caused by high amounts of distributed generation, such as rooftop photovoltaic (PV) systems, in the low voltage grid. High voltages are caused by increasing distributed generation as the Swedish power grid shifts from centralised to decentralised power production. The aim was to manage overvol
This study investigates the evolving strategic role of Human Resources (HR) in today’s volatile, uncertain, complex and ambiguous (VUCA) environment. By comparing perspectives of HR-leaders and CEOs, HR’s strategic contribution is explored, as well as the barriers limiting its influence and the priorities needed for driving increased organisational success. A qualitative, comparative approach was
More often than not one would encounter a problem, know that the solution has to meet some requirements, but do not how to start or how to progress towards solving it. Motivation for a computer that can solve the problem automatically without explicitly programming it is apparent, i.e. a computer that \programs itself", is greatly desired. The method of genetic programming has demonstrated it
The development ideals of linear progress, modernization and economic growth are based on one worldview among many, but have nonetheless been able to dominate global politics. Critical development literature has shown how indigenous peoples’ cosmologies have been pushed aside since colonialism, deemed traditional and backwards. There is a growing interest in searching for alternatives to the devel
Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. Whispering Gallery Mode Resonators have small mode volumes and strong beam confinement leading to high Quali
The Arctic is experiencing a phenomenon called Arctic amplification (AA) which has caused a rapid warming rate two to three times greater than that of the Northern Hemisphere (NH) or global in both observed and modelled data over the past few decades. Previous studies focused mostly on temperature and sea ice albedo feedbacks; however, the impacts of biosphere feedbacks especially from carbon cycl
Agricultural subsidies and taxation policies in Norway remain heavily skewed toward livestock, reinforcing structural barriers that hinder the transition toward sustainable and plant-based food systems. This study examines how policy drivers and barriers sustain Norway’s meat-dominated agricultural model and limit the development of plant-based production. To address this aim, the thesis investiga
This study examines whether state legitimacy can contribute to peace by analyzing how legitimacy has impacted levels of negative peace in Somalia and Somaliland since the collapse of the Somali state in 1991. Despite their similar historical cultural and social societal foundations, the two entities have followed remarking different political trajectories, with Somaliland experiencing significantl
