High-energy synchrotron X-ray diffraction offers the unique combination of high spatial resolution and bulk material penetration power, which is well suited for the investigation of strain fields around cracks in engineering materials. The speed of data acquisition also lends itself to the observation of in-situ processes, such as crack propagation. This potential has been only partially explored

Abstract in UndeterminedThe use of a polar diagram method for describing and evaluating the machinability ofInconel 718 was explored. Five key parameters of the work material, representing themechanical and physical properties, which have the strongest influence on its machinability,were employed in the diagrams. These five parameters were integrated into asingle polar diagram, used to describe th

Although Moral Foundations Theory claims that the foundations of morality are universal, there are still few studies addressing it through non-English measures. In the current research, 540 persons filled out a Swedish translation of the Moral Foundations Questionnaire, and 332 of them filled out political attitude measures. Confirmatory factor analyses suggested that the fit of the five-factor mo

Purpose – The purpose of this paper is to provide a theoretical framework for conceptualizing critical and creative thinking within doctoral study and to illuminate the connecting and diverging points between the two phenomena in a way that clarifies their developmental relationships. Design/methodology/approach – The conceptual framework is founded in a synthesized understanding of both new and

The 1920s saw a significant exchange between eugenicists in Swedenand the young Soviet state. Sweden did not take part in World War I, and duringthe years following immediately upon the Versailles peace treaty, Swedishscholars came to serve as an intermediary link between, on the one hand, SovietRussia and Weimar Germany, and, on the other hand, Western powers. Swedisheugenicists organized confere

This article focuses on Olof von Dalin’s occasional verse, which has not yet been collected in a scholarly edition. Dalin's occasional poems have survived thanks to many people. Some of them were personal friends and acquaintances of his while others did not move in his circles and were not personally known to him. They copied his poems and in not a few cases made sure that they were printed; they

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

Popular Abstract in English Parkinson’s disease is the second common neurological disease whose major clinical symptom is progressive impairment in the ability to control the body movements. The symptoms are mainly caused by the gradual loss of dopamine producing neurons in a very specific part of the brain, termed substantia nigra. Although there exist some drug and surgical therapies, those mosParkinson’s disease is a progressive neurodegenerative disorder. Since the motor manifestations of the disease is associated with the loss of dopaminergic (DAergic) neurons in the substantia nigra pars compacta, cell replacement therapy is a promising approach for treatment. Although several different cell types have been used in clinical trials, with the recent findings of somatic cell nuclear tr

The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential and model reduction methods are very useful tools. This thesis combines the areas of modeling and mo

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

Vi har redogjort för K2- och K3-regelverken och i praktiken finns tydliga skillnader. I K2-regelverket finns begränsande förenklingsregler och i K3-regelverket ges möjlighet att göra egna bedömningar och utforma redovisning och årsredovisning efter företagets situation. I slutsatsen utgår vi från ett medelstort företag, vilket vi definierar som ett företag som ligger över gränsvärdet 50/25/50 men

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

Bakgrund: Kunskapsintensivt arbete utgör en allt större del av näringslivet idag. Morgondagens vinnare blir de företag med den mest kompetenta personalen. Organisationen som ligger till grund för detta arbete står inför en omfattande förändring som en del av organisationens strategi för att uppnå en långsiktig konkurrenskraft. För att möjliggöra detta krävs en kompetensutvecklingsstrategi som även

Care of older persons in community and primary care differs substantially between European countries, but most countries pursue the concept of “ageing in place”, meaning that most older people do not live in institutions. More and more older people are living alone. Relatives still play an important role in the care of older people, but it differs substantially within Europe, and will probably rem
