Background: Many blood group antigens are carried by red cell surface proteins, thefunctions of which are not yet fully characterized or in some cases completelyunknown. By investigating red cells with naturally-occurring blood group variants,much has been learnt about the underlying molecules. However, interindividualvariation affecting other molecules than the one(s) of interest may confound oro

För att bättre kunna förebygga att skelettet bryts ner vid långvarig vila eller vid sjukdomarsom osteopenia och osteoporos, behövs bättre förståelse för de processer somstyr detta. I den här avhandlingen antas att den primära orsaken till bentillväxt är enförändring i den kemiska miljön i benet. Förändringen antas orsakas av att tillväxtstimulerandeämnen transporteras genom benet till den plats däIn order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. The change in the chemica

Background: The observation of differences in the way apparently similar patients are treated from one health care setting to another, i.e., practice variation, have been recognized in numerous studies. The variations across the health care settings have been shown to exist for different outcomes. However, any measurement of any system will reveal some form of variation and this normal inevitable

Commitment to involuntary care is a multistage process comprising many different aspects; legal, psychological, medical, social and ethical among others. It can also be analyzed from the perspective of a continuum starting from the report to the social authorities, the evaluations on whether to commit or not, the actual commitment and aftercare following involuntary treatment. Enhancing knowledge

The subject of this thesis is the clinical use of transesophageal echocardiography (TEE) in patients with stroke or atrial fibrillation. Subjects were examined with echocardiography and sonography of the carotid artery. A control group of randomly selected volunteers without cerebrovascular disease was compared to patients with ischemic stroke. Cardiac pathology was classified as minor potential e

The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts th

Popular Abstract in Swedish Något som kan låta motsägelsefullt är att en stjärna fungerar som en svartkropp. Med svartkropp menas ett objekt, vilkens energiförlust i form av elektromagnetisk strålning bestäms av föremålets temperatur och storlek. Våglängderna på strålningen som lämnar ett objekt bestäms däremot endast av temperaturen. En snöboll med temperaturen -10 C strålar 271 W m$^{-2}$ medanThe spectra of symbiotic stars are shown to frequently contain numerous fluorescence lines caused by Photo-excitation by Accidental Resonance (PAR). So far, most work involving fluorescence in stellar spectra has been assigned to the search of new PAR mechanisms, which can explain the presence of certain emission lines. This is taken a step further as the PAR pumped emission lines are analyzed to

Popular Abstract in Swedish Avhandlingen är indelad i två delar. I den första delen studeras hur kommunikation påverkar utfall i strategiska situationer, så kallade spel. Den andra delen studerar individers riskpreferenser. Metodologiskt förlitar sig avhandlingen till största delen på ekonomiska experiment. I kapitel 2 till 4, som är författade tillsammans med Ola Andersson, studeras effekterna aThis thesis is divided into two distinct parts. The first part studies communication in games and the second part investigates individual decision making under risk. Chapters 2 – 4, co-authored with Ola Andersson, investigate communication and renegotiation in dynamic games. In Chapter 2, Bertrand supergames with non-binding communication are used to study price formation and stability of collus

Breast cancer is a truly heterogenous disease, reflected in the existence of a wide spectrum of phenotypic subsets of tumours with varying intrinsic aggressiveness as well as ability to respond to a given treatment. Recent advances in large-scale genomic and proteomic screening techniques have confirmed this heterogeneity also at a molecular level, but there is still a bottleneck to be overcome be

Popular Abstract in Swedish Tillgången på energi har varit av stor betydelse för utvecklingen av det det moderna industrisamhället. Samtidigt skapar energianvändningen ett flertal miljöproblem med lokal, regional och global utbredning. Syftet med denna avhandling är att studera olika strategier för att minska miljöpåverkan från det svenska energisystemet och bedöma strategiernas tekniska och ekonoEnergy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. Part I (two articles) deals with how energy efficiency improvements and the increas

The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. These approaches often lead to satisfactory results, but they could be augment

The starting point of this study is the striking similarities between late modern notions of anthropogenic climate change and premodern ideas about divine punishment. In both these cases the occurrence of future disasters have been directly linked to the moral behavior of the endangered. What threatens to befall man is considered to be his own fault. Hence urgent calls have been made for each and

The aim of the present study is to study the Abscopal regression of subcutaneously implanted N29 rat glioma after immunization with syngeneic IFNg secreting cells and treatment of contra-lateral tumours with pulsed electric fields (PEF) and/or radiation therapy (RT). The study was performed on rats of the Fischer-344 strain with rat glioma N29 tumours implanted subcutaneously on the flank or on bo

Windmill structures must withstand very high horizontal loading giving an extremely large overturning moment on the foundation. These structures have very low stability loads in comparison to the overturning loads. The traditional way to solve the construction problem uses a shallow foundation with a massive concrete volume or a piled foundation to resist the extreme overturning moment. This work

Genom att teckna en avbrottsförsäkring kan ett företag skydda sig mot de inkomstförluster som riskerar att uppstå om verksamheten drabbas av ett avbrott. För att full försäkringsersättning ska utgå vid ett avbrott fordras emellertid att det försäkrade företaget inte, i strid med 8 kap. 11 § försäkringsavtalslagen (FAL), förvärrat det inträffade försäkringsfallet eller åsidosatt sin plikt att, enliBy entering a business interruption insurance policy agreement, a company can protect itself against the risk of sustaining economic losses following an interruption of the company’s business. In order for the insured company to receive full compensation in the event of an interruption, the company must not, in violation of Section 11 of Chapter 8 of the Insurance Contracts Act (ICA), have exacerb

Enligt svensk rätt har den som utsätts för förföljelse på grund av sin faktiska eller tillskrivna sexuella läggning rätt att erhålla flyktingstatus. En svårighet med att bedöma asylsökandens sexuella läggning är att det ofta saknas bevisning. Domstolen får därför göra en trovärdighetsbedömning av asylsökandens påstående om den sexuella läggningen. Bedömningarna i dessa mål har kritiserats för att According to Swedish law, those who are persecuted because of their actual or attributed sexual orientation have the right to obtain refugee status. However, such asylum cases are often difficult to assess, as there is often no evidence. The court shall therefore make a credibility assessment of the asylum seeker’s claim about the sexual orientation. The assessments have been criticized, because o

I avtalsrätten utgörs en central princip av pacta sunt servanda – löften ska hållas. Denna princip, som på ytan kanske inte ser ut att innebära några svårigheter, kan leda till bekymmer sett inom ramen för användandet av letter of intent respektive letter of comfort. I det moderna näringslivet har ett flertal sätt att sluta kommersiella avtal vuxit fram och lett till att avtalslagens anbud-accepOne fundamental principle within the field of contract law is pacta sunt servanda - agreements must be kept. This principle, which on the surface might not seem very complicated, may cause problems when applied on the use of letter of intent and letter of comfort. In the modern business world several ways of entering commercial contracts have arisen, causing the offer-and-acceptance-model provide

The changing customers’ behavior nowadays strongly affects the market situation in any type of industries. Markets are demanding a shorter delivery lead time, shorter product life cycle and higher flexibility to fulfill customers’ expectation. In order to fully adapt in this kind of situation and maintain competitiveness in the market, a company need to have better collaboration internally and ext
