11. Gas Metal Arc Melt Pool Modelling : Effect of welding position and electromagnetic force mode
Sammanfattning : Gas metal arc is a high-efficiency and widely used heat source for metal processing applied predominantly in welding and additive manufacturing. In this study, it was applied to welding. LÄS MER
12. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners
Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER
13. Force Budget Analysis of Glacier Flow : Ice Dynamical Studies on Storglaciären, Sweden, and Ice Flow Investigations of Outlet Glaciers in Dronning Maud Land, Antarctica
Sammanfattning : This thesis contributes to the understanding of glacier response to climate change by ice dynamical studies on Storglaciären, Sweden, and Bonnevie-Svendsenbreen, Kibergbreen and Plogbreen in Dronning Maud Land, Antarctica. Ice surface velocities, ice geometry and temperature information is fed through a force budget model to calculate ice mass outflux of these glacial systems via three-dimensional stress distributions for a flux-gate.

14. Surface Force and Friction : effects of adsorbed layers and surface topography
Sammanfattning : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. LÄS MER
15. The Force of Blood : Epidemiological studies of blood pressure in stroke, atrial fibrillation and primary care
Sammanfattning : Aim: The overarching aim of this thesis was to investigate the prevalence, temporal trends and associations to cardiovascular outcomes of blood pressure levels in patients in Västra Götaland. Methods and findings: In Study I, Cox regression analysis was used to investigate associations between blood pressure and mortality in 799 patients with acute ischemic stroke who were identified in the quality register of a stroke ward at Sahlgrenska University Hospital.
