Popular Abstract in Swedish Populärvetenskaplig sammanfattning Hyaluronan (hyaluronsyra) är en högmolekylär polysackarid som förekommer i all biologisk vävnad i olika koncentrationer, med särskilt höga nivåer i bindväv. Den kan bildas av de flesta celltyper. På molekylär nivå föreligger den i form av ett nystan, har förmågan att binda stora mängder vatten, och har en uttalad pseudoplasticitet. HyaHyaluronan has been found in the eye in varying amounts and at different sites. It is involved in physiological and pathological processes, though many aspects of its bio-logi-cal functions are still unclear. We have studied the role of iris tissue in hyal-uro-nan production in the anterior segment of the eye, and its changes after trauma. After peripheral iridectomy or argon laser treatment, the

Popular Abstract in Swedish Denna avhandling har tre huvudsakliga mål. Det första är att argumentera för en tolkning av politisk frihet som innebär att frihet föreligger i den utsträckning man inte är dominerad av andra: frihet som icke-dominans. Detta skiljer sig från den vanligare tolkningen av frihet som innebär att frihet föreligger i den utsträckning ingen annan interfererar med det man gör: This dissertation argues for an interpretation of liberty in terms of non-domination rather than non-interference, that non-domination can work as an independent criterion of political legitimacy, and that non-domination includes an approximation of equality in socioeconomic goods. In the first part, four theories of liberty and power – those of Kant, Locke, J. S. Mill and H. Taylor, and Wollstone

We present a method to compute, quickly and efficiently, the mutual information achieved by an IID (independent identically distributed) complex Gaussian input on a block Rayleigh-faded channel. The method accommodates both scalar and MIMO (multiple-input multiple-output) settings. Operationally, the mutual information thus computed represents the highest spectral efficiency that can be attained u

We present the first implementation of Thread-Level Speculation in combination with Just-in-time compilation. The implementation is done in Google’s V8, a well-known JavaScript engine, and evaluated on 15 popular web application executing on 2, 4, and 8 core computers. Our results show an average speedup of 2.9 on 4 cores, without any JavaScript code modifications. Further, we have found that the

Robots interacting with other agents in rich information landscapes and complex dynamic physical environments require sophisticated and robust concept and knowledge management capabilities if they are to solve problems, communicate, learn and exhibit intelligent behaviours. In this paper we describe how conceptual spaces provide a powerful substrate upon which to build effective concept and knowle

Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100 μm or shorter. However, 6 out of 31 excess sources studied in the Herschel Open Time Key Programme, DUNES, have been seen to show significant—and in some cases extended—excess emission at 160 μm, which is larger than the 100 μm excess. This excess emission has been attributed to circumstellar d

Issues of sustainable agriculture have much relevance and urgency for the sustainable production of non-eatable products that have an agricultural origin, such as biofuels. In the chapter the opinion is expressed that joint legal regulations on sustainable use of natural resources and sustainable farming methods for eatable and non-eatable products of an agricultural origin can be an efficient sol
