Many psychiatric illnesses are associated with early mortality and with an increased risk of developing physical diseases that are more typically seen in the elderly. Moreover, certain psychiatric illnesses may be associated with accelerated cellular aging, evidenced by shortened leukocyte telomere length (LTL), which could underlie this association. Shortened LTL reflects a cell's mitotic history

The Euro50 is a proposed optical telescope with an equivalent aperture of 50 m. It will have a segmented primary mirror and full adaptive optics. To study the interaction of the telescope structure, the control system and the optics, an integrated simulation model has been formulated. The mechanical model is a modal version of an Ansys finite element model. The optics model is based on ray tracing

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

Demands for efficient, greener, economical and sustainable production of chemicals, materials and energy have led to development of industrial biotechnology as a key technology area to provide such products from bio-based raw materials from agricultural-, forestry- and related industrial residues and by-products. For the bio-based industry, it is essential to develop a number of building blocks or

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

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
