Populärvetenskaplig sammanfattningDet senaste århundradet har den tekniska utvecklingen gått snabbt inom många områden. Jordbruket är ett av dessa. Idag upptas ungefär en tredjedel av jordens landyta av jordbruk och boskapsskötsel. Utvecklingen av jordbruket har inneburit att vi idag kan producera mer mat än någonsin, men den har också inneburit intensivare brukningsmetoder, genom till exempel ökaAbstractHuman ingenuity and activities have resulted in erosion of ecosystems and their capacity to support the sustainable production of goods and functions that we depend on. Biodiversity i.e. the diversity within and between species and of ecosystems, underpins many of the ecosystem functions critical for human well-being and resilience, and is declining faster than at any time in human history

Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. Engine emissions such as carbon dioxide that has an effect on a global scale and other harmful emissions that affect on a local scale such as soot and nitrogen oxides are on the rise, forcing the countries to t

Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. Mercury is present at 1000 times lower concentrations than the other two metals, but still has a negative impact on the environment due to its high trans

Accurate knowledge about the amount and dynamics of terrestrial gross primary productivity is an important component for understanding of ecosystem functioning and processes. Recently a new diagnostic model, Southampton Carbon Flux (SCARF), was developed to predict terrestrial gross primary productivity at regional to global scale based on a chlorophyll index derived from MERIS data. The model aim

Popular Abstract in Swedish None.This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. One 2D and one 3D model were considered for the fixed bed combustion. The introducto

Mechanisms controlling microbial degradation of dissolved organic matter (DOM) in aquatic environments are poorly understood, although microbes are crucial to global nutrient cycling. Bacterial cell wall components may be one of the keys in understanding the presence of slowly degrading DOM in nature. We found that dominant components of bacterial cell walls (D-amino acids (D-AA), glucosamine (Glu

Association studies were carried out in a sample of 86 patients from Sweden who had survived a myocardial infarction (MI) at a young age and 93 age-matched healthy individuals, to compare the impact of polymorphisms at the apolipoprotein (apo) AI-CIII-AIV gene cluster on among-individual differences in plasma lipid and lipoprotein traits, the five high density lipoprotein (HDL) subclasses (2b to 3

Popular Abstract in Swedish Ett viktigt steg i strävan att ersätta fossila bränslen med biobränslen är ett effektivt utnyttjande av förnyelsebar lignocellulosa. Råmaterialet är restprodukter från skogs- och jordbruksindustrin och består bl. a. av komplexa kolhydrater som cellulosa. Efter nedbrytning till enkla sockermolekyler kan dessa omvandlas till bioetanol genom jäsning. Sockret som extraherasIn 2009 the EU approved two directives as a first initiative towards reducing greenhouse gas emissions and becoming independent of fossil fuels: the Renewable Energy Directive and the Fuel Quality Directive. As a result, the demand for biofuels will increase enormously over the next decade, both nationally and in the entire EU. This huge demand will require a more advanced type of biofuels, produc

Popular Abstract in Swedish Knäartros är en mycket vanlig sjukdom som leder till successiv nedbrytning och förlust av brosket i leden, en process som oftast tar 10-20 år. Detta orsakar svår smärta och stelhet och i dag saknas botande behandling mot artros. Det är dock rimligt att anta att en behandling har bättre förutsättningar att lyckas ju tidigare den sätts in. Man vet att det tidigt under sjuDelayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a new technique to study cartilage glycosaminoglycan (GAG) content. The negatively charged contrast agent Gd-DTPA2-, injected intravenously, distributes in the cartilage inversely to the likewise negatively charged GAG. The GAG concentration is reflected by the MRI parameter T1 and the Gd-DTPA2- concentration by the MRI parameter R1 (R1=1/T

Combustion of fossil diesel is a major environmental problem for both the climate and human health. Renewable diesel fuels have been developed and introduced to the market to reduce the net CO2 emissions. Emission control strategies, such as aftertreatment systems, have been implemented to reduce the health hazardous particulate matter (PM) and nitrogen oxides (NOx) emissions. The overall aim of t

BACKGROUND: Based on clinical and genetic associations, axial spondyloarthritis (axSpA) and inflammatory bowel disease (IBD) are suspected to have a linked pathogenesis. Gut dysbiosis, intrinsic to IBD, has also been observed in axSpA. It is, however, not established to what degree gut dysbiosis is associated with axSpA disease severity. The objective of this study was to compare gut dysbiosis fre

Popular Abstract in Swedish Konkurrensen har ökat markant under 2000-talet med ökad globalisering och hållbarhetstrender. Ständigt pågående teknologiska utvecklingar har medfört att kraven på rätt kvalitet på varor och tjänster har ökat. Tillverkare måste också följa skärpningar inom lagstiftning och krav på spårbarhet. Det har sammantaget lett till att det ställs allt hårdare krav på effektiv förToday’s trends are the ever growing competition with increased globalization and sustainability. Together with ongoing technological developments and the demand for right quality of products and services, this has also resulted in increased demands for legislation and traceability. This development has also had an impact on packaging and Packaging Logistics. This thesis deals with packaging, logis

Att bli förälder är en stor omställning i livet och kan förändra arbetssituationen, relationer och den egna personliga utvecklingen. Föräldraskap upplevs ofta som starkt könsbundet och kvinnor över hela världen tar på sig mer hushållsarbete och barnomsorg än män, även i Sverige. Trots att Sverige har en generös och könsneutral föräldraledighet finns det fortfarande ojämlikheter i hur föräldrar hanThis thesis explored gendered parenthood and parents’ experiences of their work- family interface through the COVID-19 pandemic. This thesis draws on decades of analysis of gendered labor division, father involvement, and the work-family interface to understand developments and tensions before the pandemic. It then positions the pandemic as a global ‘developmental event’ due to the restrictions im

This thesis consists of four self-contained chapters that explore two areas in development economics: the impact of geography and climate on health, learning, and financial decision-making, and the influence of history and culture on human and social capital.In the first chapter, we study the effect of waterborne disease risk on children’s health and learning in Tanzania. Using a hydrological mode

The global aviation industry is experiencing growing pressure to decarbonize, driving significant demand for Sustainable Aviation Fuel (SAF). Second-generation feedstocks that do not directly compete with food crops, such as lipid oils from insects and lignin-derived oils, are promising sources, but their high concentrations of inorganic contaminants and oxygen make them incompatible with existing

Background: The association between different patterns of healthcare use and non-recovery in patients with spinal disorders is unclear. We aimed to assess the association between healthcare use and non-recovery 6 months after a specialist evaluation in Norwegian secondary care and whether non-recovery was linked to adherence to specialist-recommended care. Methods: This observational registry-base

Background: Hearing loss is estimated to affect more than 20% of the global population. Hearing aid fitting is a common intervention in audiological rehabilitation; however, there are still those who struggle with remaining communication difficulties that require additional intervention. The group rehabilitation program Active Communication Education (ACE) has been shown to be an effective alterna

Climate change and connected environmental disruptions have a large negativeeffect on the health of humans and other species. Improved understanding ofknown links in the environment-disease nexus as well as knowledge gaps isessential to prepare for and mitigate this escalating threat. However, knowledgefragments are scattered across millions of scientific articles making informationsynthesis too c

Throughout the last decades, the social responsibility of corporations has undergone significant changes. From revolving around self-regulation, voluntariness, and soft law, the regulatory landscape has expanded to involve harder demands on corporations, such as mandatory sustainability due diligence. This thesis considers these changes as a hardening of Corporate Social Responsibility (CSR), and

BackgroundMolecular subtypes of lung adenocarcinoma (LUAD) with varying prognosis and characteristics have been proposed based on one or two-dimensional studies but are not yet implemented into clinical routine. Epigenetic modifications in cancer cells are independent of sequence variants, directly linked to gene and genome regulation, and thus provide important information to guide subclassificat
