It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. Gases and airborne particles may cause negative health effects and the respiratory system is exceptional sensitive. Isocyanate is one group of substances that are
The thesis consists of an introductory chapter, followed by three chapters which all deal with theoretical issues related to moral hazard and insurance. In Chapter 2 we assume symmetric and perfect information. We conclude that, given some standard assumptions, the expected utility function cannot be quasi-concave, which strengthens earlier findings in the literature. As a consequence convex prefe
Methods for identification and valuation of Ecosystem Services (ES) have been developed and applied worldwide in purpose to better consider nature in land planning decisions. In Sweden each municipality has a spatial planning monopoly and with that comes differences in prerequisites for sustainable land and water usage within the country. A growing number of actors are offering ES-analyses as a pu
Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines. Model libraries provide an excellent way to package engineerin
The aim of this thesis was to define and develop the concept of health promotion in mental health services as well as to develop a questionnaire to measure patients? subjective experiences of health promotion intervention in mental health services. The samples consisted of 12 patients in study I and 12 nurses in study II as well as 135 patients in mental health services in study III and IV. Data w
Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound. A prediction model of the subjective response, in a pai
The aim of this thesis is to contribute to our understanding of health care utilisation and its determinants in developing countries, especially in sub-Saharan Africa. This is done by explicitly focusing on health care expenditures and its determinants as well as the choice to seek health care to cure the illness. Firstly, the focus is on a household’s expenditures for health care. The aim of this
Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. The fuel cell, being the more efficient power generator of the two, represents the maj
Renal artery stenosis (RAS) causes hypertension, decreased glomerular filteration rate (GFR), and renal ischemia. RAS is progressive and causes 5-16% of all cases of renal failure. Prevalence of RAS in patients with hypertension is 1-5%. Today percutaneous transluminal renal angioplasty (PTRA) with or without stenting is a widely accepted treatment of RAS. Treatment of renal artery occlusion (RAO)
Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. The subject of this work was the extraction of lignin from kraft cooking liquor using ceramic ultrafiltrati
