Large eddy simulations (LES) and experiments (planar laser-induced fluorescence of the hydroxyl radical (OH-PLIF) and pressure transducer) have been carried out on a gas turbine burner fitted to an atmospheric combustion rig. This burner, from the Siemens SGT-800 gas turbine, is a low NOx, partially premixed burner, where preheat air temperature, flame temperature, and pressure drop across the bur

Det relativt lugna området bakom barriärö är en fördelaktig plats för hamn trots att navigationen genom själva inloppet kan vara utmanande. Olika åtgärder såsom muddring eller kuststrukturer kan vara nöd-vändiga för att säkerställa det önskade vattendjupet för en säker navigering. Island som är en önation är beroende av tillförlitliga navigeringsvägar som förbinder hamnar med havet. DThe relatively calm area behind barrier island are favored locations for harbors even though the navigation through the inlet itself can be challenging. Different measures like dredging or coastal structures might be necessary to ensure the desired water depth to maintain a safe navigation. Iceland as an island country depends strongly on reliable navigational routes connecting harbors to the ocea

Popular Abstract in Swedish Vid Typ 1 diabetes mellitus (insulinberoende, [ungdoms]) förlorar kroppen förmågan att tillverka insulin, det hormon som styr upptaget av socker i kroppens celler. Insulinet bildas av bukspottskörtelns hormonproducerande betaceller, och Typ 1 diabetes orsakas av att dessa celler skadas och förstörs. Denna skadeprocess anses idag i de flesta fall förmedlas av kroppens egAutoantibodies against glutamic acid decarboxylase (GADA), protein tyrosine-phosphatase-like protein (IAÐ2A), and/or pancreatic islet cells (ICA) are autoimmune markers usually present at diagnosis of Type 1 diabetes. Type 1 diabetes is therefore in general believed to be caused by an immune-mediated beta cell destruction. In children this destruction is fast, whereas in adult patients Type 1 diab

When Swedish wastewater treatment plants were rebuilt to include enhanced nitrogen removal, anaerobic ammonium oxidation (anammox) was far from being a mature technology. During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is decreasing, but lab- and pilot-scale studies on real municipal wastewater are yet lackin

Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. The challenge to overcome here is to achieve high-accuracy machining solutions, in spite of the

Force sensing provides robots the capability to accomplish tasks where physical interaction with the environment is required, such as assembly. Small position uncertainties can then be corrected for by sensing the contact forces. This thesis considers the problem of force-controlled assembly, including how tasks can be specified in a simple and intuitive way and how robust task execution under unc

The purpose of this study was to explore neuroretinal transplantation in a large animal model of severe retinitis pigmentosa and to establish graft development, long-term survival, graft-host integration, and effects on the host retina. Methods Rhodopsin transgenic pigs, aged 6 months, received in one eye a fetal full-thickness neuroretinal sheet in the subretinal space by means of vitrectomy and

Information technology is a vital driver in today’s business environment. Recent developments of IT have facilitated for the relatively easy creation of markets on the Internet, so called B2B-marketplaces. However, judging from the survival rate of B2B-marketplaces (5 to 10 per cent), it seems like B2B-marketplaces are doing something wrong. This paper scrutinises several theoretical frameworks re
