This paper presents a theoretically and methodologically grounded GIS-based model for the measurement and mapping of an index of living conditions in urban residential areas across Sweden. Further, the model is compared and evaluated using the Swedish Police’s assessment of crime-exposed areas. The results indicate that the geographically measured vulnerable living conditions overlap to a large ex
Background: Severe diminished foot somatosensation, for example, caused by neuropathies and advanced aging, contributes to balance deficits and increased fall risk. However, little is known about somatosensory impairment and functional and subjective balance problems in relatively healthy elderly. Method: Vibration perception thresholds (VPTs) were assessed with a biothesiometer and tactile pressu
Mathematical optimization is becoming increasingly important for engineering in general and control in particular. This thesis deals with numerical methods, primarily direct collocation, and symbolic methods, primarily block-triangular ordering and tearing, for numerical solution of general dynamic optimization problems involving dynamical systems modeled by large-scale differential-algebraic equa
Popular Abstract in Swedish Cancer är en av de vanligaste dödsorsakerna i Sverige idag och att kunna ge cancerpatienter en bättre behandling är därför av stort intresse. En del av detta arbete består av att förbättra förståelsen för hur en cellpopulation, eller då speciellt en cancertumör, växer. Ett medel för att öka kunskapen på området är att använda matematiska modeller. Förmågan att kunna föIt it of great importance to increase the knowledge of various cell cycle kinetic parameters and the objective of this thesis is to use stochastic models to interpret Bromodeoxyuridine (BrdUrd) DNA Flow Cytometry (FCM) derived data in order to estimate such parameters. The cell cycle is the process of growth and division that is essential for an organism to increase in size. The cell cycle consist
Biochemical analyses of blood can decipher physiological conditions of living animals and unravel mechanistic underpinnings of life-history strategies and trade-offs. Yet, researchers in ecology and evolution often face constraints in which methods to apply, not least due to blood volume restrictions or field settings. Here, we test the suitability of a portable biochemical analyser (Zoetis VetSca
(1) Background: The European Union Driver License Committee recently developed a questionnaire as a screening tool for obstructive sleep apnea (OSA), named the European Obstructive Sleep Apnea Screening (EUROSAS) questionnaire for drivers. The aim of the current study was to investigate the diagnostic performance of the EUROSAS to predict risk of OSA in professional male drivers. (2) Methods: Fift
The partitioning of Bacillus stearothermophilus lactate dehydrogenase (LDH) in an aqueous two-phase system was studied. Particularly, the influence of tyrosine tags on the partitioning was evaluated. The hydrophobic effect, caused by the addition of tyrosine residues, was determined in a system based on dextran and the thermoseparating ethylene oxide-propylene oxide random copolymer (EO30PO70). Fi
Background: The study of thoracic injuries and biomechanics during CPR requires detailed studies that are very scarce. The role of the heart in CPR biomechanics has not been determined. This study aimed to determine the risk factors importance for serious ribcage damage due to CPR. Methods: Data were collected from a prospective registry of out-of-hospital cardiac arrest between April 2014 and Apr
The first years of life are a critical period of development, and circumstances during this period can affect individuals throughout life. But to what extent do disadvantaged circumstances in childhood affect individual wellbeing in later life and for whom? Can interventions in childhood break adversity over the life course? For whom are interventions most effective and why? This thesis aims to in
The MAM blood group system (International Society of Blood Transfusion [ISBT] 041) consists of one high-prevalence antigen to date, first detected in a 31-year-old woman during her third pregnancy. Epithelial membrane protein 3 (EMP3) was recently identified as the gene coding the MAM antigen. Six unique genetic variants have been described in EMP3 in 11 MAM- individuals. EMP3 is an 18-kDa glycopr
Internationella kommersiella avtal medför en ökad risk för att ändrade förhållanden påverkar parternas möjligheter till fullgörelse. Uppsatsen undersöker främst säljarens möjligheter att undgå skadeståndsansvar vid fullgörelsehinder, särskilt mot bakgrund av Covid-19 pandemin. Fokus i uppsatsen ligger på tillämpliga lagregler, principerna om force majeure och hardship samt force majeure och hardshInternational commercial contracts involve a greater risk of change of circumstances affecting the parties’ possibility to perform. This thesis mainly examines how the seller can avoid liability to pay damages because of non-performance, especially in relation to the Covid-19 pandemic. Focus is on domestic rules and the force majeure and hardship excuses. A legal dogmatic method with a comparative
The valorization of lignin offers sustainable and renewable products and materials. For that reason lignin needs to be further analyzed although the various challenges this process implicates. The major obstacles in this field are lignin’s chemical heterogeneity, all the modifications in lignin’s chemical structure owing to its extraction method and purification process and the lack of appropriate
The European Energy production system is in transition towards renewable energy sources (RES). Concrete targets have been set through the European Union “Energy Roadmap 2050”. The transition has started by national states but concrete action towards the targets has been mainly taken up at a local level. In this context, this research work aims at exploring how can a community trigger and drive an
The thesis describes and analyzes individuals' experiences of reduced working hours with retained salary, as well as how this could potentially enable an improved work-life balance. It also investigates how participants experienced pros and cons with reduced working hours. The topic is relevant due to the ongoing societal debate about whether the current 40-hour workweek in Sweden shoul
An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax
To reduce pollution and green house gas emissions associated with plastic production and waste, biobased production of the biodegradable plastic, polyhydroxybutyrate (PHB), is suggested to be a good substitute to petrochemically derived plastics used in foodstuff packaging. However, bacterial production of PHB has proven costly and production with plants occurs at the expense of arable land. Oleag
The presence of phytate in plants-based food is considered a threat to proper nutrition in developing countries and in particular in rural areas. There is evidence of micronutrient deficiencies due to the presence of phytate in plant-based diets. People from low income households are most affected by diets rich in phytate. The aim of this study was to investigate different processes through which
