1. Influence of waxes on bitumen and asphalt concrete mixture performance
Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER
2. Short-term effects of ambient temperature on daily deaths and hospital admissions
Sammanfattning : Background: Incidence of death and hospitalizations have been observed to depend on short-term changes in weather and to increase with extreme temperatures. This thesis aims to strengthen the scientific knowledge on the relationship between temperature and daily deaths, but also the relationship between temperature and daily hospital admissions. LÄS MER
3. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth
Sammanfattning : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. LÄS MER
4. Integral and local AC-susceptibility : instrumentation and applications
Sammanfattning : This thesis presents my mostly unpublished experimental work related to two major contributions with the design of: A high precision and versatile bulk average(or integral) AC-susceptometer and its application to investigations of exchange anisotropy in Co multilayers. A novel Local Susceptibility measurement technique exploiting the narrow gap in inductive ring-heads in magnetic recording technology. LÄS MER
5. Psychological and physiological effects on Swedish worker’s health when using a health promotion intervention including mechanical massage and mental training - a pilot study
Sammanfattning : Introduction:Work-related stress is one of the most challenging issues on workplaces. Reduced ability to relax and recover has been proposed as a key factor behind the increase of stress-related illness among workers. Massage and mental training are two commonly used techniques which may have positive effects on the ability to recover. LÄS MER
