1. Metabolic disturbances in shift workers
Sammanfattning : An increased risk for coronary heart disease among shift workers is earlier shown in the epidemiological literature. The aim of this thesis has been to penetrate metabolic disturbances and obesity among shift workers compared to day workers, and to compare if there are differences in total mortality or cause specific mortality of coronary heart disease (CHD), diabetes or ischaemic stroke in between the two groups.

2. Geochemical and Mineralogical Characterization of Waste Rocks for Preliminary Mine Drainage Quality Prediction
Sammanfattning : Acid or neutral rock drainage (ARD or NRD) with its attendant elevated concentrations of harmful elements presents one of the main challenges related to the management of waste rocks. Low-quality drainage is a particular issue with respect to mineral deposits containing sulfide minerals, of which pyrite and pyrrhotite are especially prone to produce acidic drainage when exposed to oxygen and water.

3. Shift work and cardiovascular disease
Sammanfattning : Shift work is often defined as working time outside daytime hours (06:00 to 18:00). In recent years, shift work has been associated with an increased risk of cardiovascular disease (CVD), type II diabetes, and the metabolic syndrome. While some studies support the associations, others do not. Therefore, more research is needed. LÄS MER
4. Shift work and cardiovascular disease
Sammanfattning : Shift work is a work schedule being the opposite of normal daytime work, often defined as working time outside normal daytime hours (06:00 to 18:00). In recent years, shift work has been associated with an increased risk of numerous chronic conditions including for example cardiovascular disease, some types of cancer, type II diabetes, and the metabolic syndrome.
