1. Expressions of shared interpretations - Intangible outcomes of continuous quality improvement efforts in health- and elderly care
Sammanfattning : This thesis is anchored in improvement science, the research field of improvement. Improvement science describes and explores improvement in real-life contexts and “system of profound knowledge” (Deming, 2000) is a cornerstone. LÄS MER
Sammanfattning : Proactive behaviour implies taking initiative and mastering unexpected situations, and hence, is desirable in different situations. The present thesis includes three empirical studies intended to understand the consequences of proactive behaviour, as well as the factors that contribute to proactive behaviour at work and when facing unemployment.

Sammanfattning : The main objective of this work was to gain an increasedunderstanding of selected blast furnace phenomena which couldbe utilized for an improved blast furnace process control. Thisthesis contributes with both a model study and an experimentalstudy on blast furnace tapping, and results from these findingscan be used to enhance the control of the blast furnace. LÄS MER
Sammanfattning : To provide a better understanding of how frazil ice deposits on trash racks at water intakes, the phenomenon was video recorded at two hydropower plants and in a refrigerated laboratory flume. Initial accretion of frazil ice around a single bar and the motion of particles in the vicinity of an obstacle was simulated through numerical modelling and studied using plastic particles in a laboratory flume.
