De arabiska frivilliga - en transnationell social rörelses uppgång och fall

Artiklen "beskriver den islamistiska jihadrörelsens upgång och fall utifrån dels politiska möjlighetsstrukturer dels tolkningsramar och kollektiv identitet. Jihadrörelsen i Afghanistan byggdes upp i allians med vitt skilda men mäktiga aktörer med lika skilda intressen, men lämnades att 'självdö' när dessa aktörer fått sina mål uppfyllda. En således hårdnande politisk möjlighetsstruktur ledd här ti

Optimum modulo 2m multidimensional transform diffusion in block ciphers

Linear transform structures as "diffusers" for iterative block ciphers of the substitution/linear-transformation type with symbols in Z2m, the ring of integers modulo 2m were considered. In such a cipher, encryption was accomplished by passing the plaintext input through a succession of "rounds". In each round, the round input was the first passed through a key-controlled substitution, which for e

The Gastrin-ECL Cell Axis. Functional Aspects

Popular Abstract in Swedish Mag-tarmkanalen utgör kroppens största hormon-producerande organ. Många av de hormon-producerande cellernas funktion är ännu okänd och mycket lite är känt om den betydelse de kan ha vid olika sjukdomar i mag-tarmkanalen. I magsäckens syraproducerande del (fundus) finns 4 hormon-producerande celler, av vilka ECL cellen (65 %) och A-lika cellen (25 %) tillsammans utgör caThe ECL cells constitute a prominent endocrine cell population in the acid-producing part of the stomach. They are controlled by circulating gastrin released from G-cells in the antrum. In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. The first aim of the study was to prepare isolated ECL cells of high purity and to study and identify regul

Reflection and Transmission Properties of a Wall-Floor Building Element: Comparison between Finite Element Model and Experimental Data

Lightweight structures made of timber material have a number of advantages; they may become cost effective in the future and they demand relatively short production duration. However, one of the main drawbacks is related to the sound transmission, as it is becoming an increasing nuisance. The differences in weight, stiffness, density and repartition compared to traditional materials have repercuss

Geographic Accessibility Analysis - Methods and Application

Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. Costs for transportation are high and are predicted to increase, new environmental demands are being imposed on transportation and rationalizations are centralizing public and commercial services. These facts make

Language-specific encoding of placement events in gestures

This study focuses on the effect of the semantics of placement verbs on placement event representations. Specifically, it explores to what extent the semantic properties of habitually used verbs guide attention to certain types of spatial information. French, which typically uses a general placement verb (mettre, 'put'), is contrasted with Dutch, which uses a set of fine-grained (semi-)obligatory

Calculation of antenna radiation center using angular momentum

An algorithm to compute the Radiation center of an antenna based on the Spherical wave expansion is introduced. The method is based on the angular momentum vector that is uniquely defined for any antenna far field pattern. The radiation center is defined as the unique point where the magnitude of the angular momentum is minimized with respect to translations of the far field. This corresponds to m

Load Balancing and Admission Control of a Parlay X Application Server

To increase the number of services and applications in the telecommunication networks a new service architecture has been proposed and specified. The consortia that initiated the new service architecture is called Parlay. Since then, there has been a continued development and 3GPP the standardization group for 3G networks, is now cooperating with Parlay. 3GPP and Parlay are together specifying the
