Home mechanical ventilation in patients with chronic respiratory failure secondary to several different diseases has become widely acceptable as the provision of ventilatory support can provide symptomatic relief and increase life expectancy. Aims: To study the selection criteria underlying the initiation of home mechanical ventilation and to quantify the effects of in relation to blood gases and

Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. In this thesis, atmospheric circulation and wind erosion were analysed to

This project focuses on how to determine the chloride content in concrete structures exposed to marine environment in an accurate way. When analyzing dust from dry drilling in concrete, it is very often a fact that the chloride profiles show extensive variations even if the sampling has been performed within a very concentrated area with the sampling points close to each other. Several authors hav

Stefan Larsson’s Conceptions in the Code makes a significant contribution to sociolegal analysis and also represents a valuable contribution to conceptual metaphor theory. By utilising the case of copyright in a digital context it explains the role that metaphor plays when the law is dealing with technological change, displaying both conceptual path-dependence as well as what is called non-legislaStefan Larsson's Conceptions in the Code contributes invaluably to socio-legal analysis and conceptual metaphor theory. By examining cases of digital copyright, Larsson elucidates the role that metaphor plays when law is accommodating technological change, displaying both conceptual path-dependence as well as non-legislative developments in law. Analyses draw from conceptual studies of property sp

Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. For instance, notochord, endothelial cells, and pancreatic mesenchyme are essential for the development of the pancreas. N-cadherin deficient-embryos suffer fro

Celiac disease is a chronic gastrointestinal disease affecting approximately 1% of the population. It is precipitated in genetically predisposed individuals by ingestion of food containing gluten or similar proteins that are present in wheat, rye and barley. The disease might present with symtoms such as malnutrition, diarrhea or abdominal bloating, but a large proportion of those afflicted by the

This thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. This approach has the advantage of not having to stipulate any functional form for the utility function, unlike the parametric approach which relies on finding a suitable functional form for the utility functio

Economic theory commonly distinguishes between different time horizons such as the short run and the long run. Models with many time horizons are easily studied in the frequency domain, because the various time horizons are associated with a particular frequency or band of frequencies. This dissertation studies wavelet methods to analyze time series. Wavelet transforms combine time and frequency r

In this study university teachers? personal theories of their pedagogical practice in basic courses in undergraduate education are described and analyzed. According to for example Polanyi (1958) and Bourdieu (1990) university teachers have developed a personal practical theory as participators in an academic social context, first as students then as teachers. This can be seen as their ?pedagogy? a

AimTo understand service users' experiences of their current mental health services and explore reflections on the Flexible Assertive Community Treatment (FACT) model and its role in future practice.MethodsA total of 17 experts participated in individual and dyadic in-depth interviews. A reflexive thematic analysis was performed on the participants' experiences of current mental health services anBackground: A person-centred and recovery-oriented approach is an integral part of modern mental health services founded on the experiential knowledge of service users. Their reflections as experts, grounded in their unique experience as service users, play a significant role in developing and improving the existing care. Experiential knowledge is therefore a means to enhance the relevance of rese

This thesis is an attempt to generate knowledge about the justification, measurement and consequences of public redistribution. The first paper poses the following question: How much redistribution from working to non-working can be justified by arguing that external resources are owned jointly by all, or that ownership should ideally be divided equally? This question is analyzed using bargaining

Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. Some isocyanates and several aromatic amines are sensitizers and listed as carcinogens.
