Studies of free gas in scattering media at micro- and macroscopic scales

Free gases in scattering media and different techniques for such studies are discussed in the present paper. Connections between two techniques that constitute a major research area at our laboratory are presented. One of the techniques concerns measurements of free gas in scattering media, such as human tissue and food products, on a small scale, while the other one is a technique for trace-gas m

Closely located dual PIFAs with T-slot induced high isolation for MIMO terminals

This paper presents an efficient technique to enhance the isolation between two closely spaced PIFAs for MIMO mobile terminals. The proposed decoupling method is based on a T-shape slot impedance transformer and it enables an inter-PIFA spacing of 1 mm to be achieved. The 10 dB impedance bandwidth and 20 dB isolation bandwidth cover the 2.4 GHz WLAN band (2.4-2.48 GHz), with a maximum isolation of

Analyticity - An Unfinished Business in Possible World Semantics

The goal of this paper is to consider how the notion of analyticity can be dealt with in model-theoretical terms. The standard approach to possible-world semantics allows us to define logical truth and necessity, but analyticity is considerably more difficult to account for.

The Double Disjunction Task as a Coordination Problem

In this paper I present the double disjunction task as introduced by Johnson-Laird. This experiment is meant to show how mental model theory explains the discrepancy between logical competence and logical performance of individuals in deductive reasoning. I review the results of the task and identify three problems in the way the task is designed, that all fall under a lack of coordination between

Biskop Sarapion av Thmuis böner

Sarapion av Thmuis böner från 300-talets Egypten är en av de äldsta bevarade samlingarna med böner från den tidiga kyrkans gudstjänstliv. Samlingen innehåller biskopens böner för begravningsgudstjänst, eukaristifirande, dopfirande, ämbetsvigningar och olika välsignelseakter. Dessa böner är en viktig källa till vår kunskap om den tidiga kyrkans gudstjänstliv och teologi i det nedre Egypten.

Biosynthesis of decorin and glypican glycosaminoglycan chains

Popular Abstract in Swedish Avhandlingen handlar om biosyntesen av proteoglykaner. Dessa består av en proteindel som har långa kedjor av sockermolekyler bundna till sig. Det finns huvudsakligen två typer av sockerkedjor, kondroitinsulfat och heparansulfat, som båda tillverkas på en identisk fyra molekyler lång sockerkedja. Man kan likna tillverkningen eller biosyntesen vid ett löpande band inne i Proteoglycans consist of core proteins substituted with glycosaminoglycan chains. The galactosaminoglycans (GlcUA/IdoUA-GalNAc) and the glucosaminoglycans (GlcUA/IdoUA-GlcNAc) are both initiated on the same tetrasaccharide linkage region GlcUA-Gal-Gal-Xyl-protein. The proteoglycan decorin is bound to collagen fibrils in the extracellular matrix and is substituted with a single galactosaminoglycan
