Den elektroniska handeln har väckt komplicerade frågor av skatterättslig karaktär, inte minst i förhållande till OECD:s modell för skatteavtal beträffande inkomst och förmögenhet, vilket mer än 1 500 dubbelbeskattningsavtal är baserade på. Internet möjliggör nämligen en ny sorts handel där företagsledningen kan befinna sig och fatta beslut från olika stater och varor och tjänster kan beställas och

Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report

In this paper we analyze the performance of three low-complexity channel estimators, based on the discrete Fourier transform (DFT), for orthogonal frequency-division multiplexing (OFDM) systems. Estimators of this type have been analyzed for discrete-time channels, and we extend this analysis to continuous-time channels. We present analytical expressions for their mean-squared error (MSE) and eval

Uppsatsen har haft en kvalitativ ansats. Syftet var att studera upplevelsen hos ett antal brandmän som i sin yrkesroll inom räddningstjänsten deltagit i denna omarbetade form av psykologisk debriefing som kallas kamratstöd. Frågeställningen har dels handlat om att undersöka hur informanterna upplevde kamratstöd och dels att svara på frågan om vilka mekanismer som kan anses verksamma i kamratstöd oThe thesis used a qualitative design. Its purpose was to study a Group of firemen´s experiences of taking part of peer support (a form of psychological debriefing) as part of their work within the Emergency Service. The research questions dealt with investigating how the interviewees had experienced peer support, what mechanisms in this method could be considered effective and how these mechanisms

Syftet med denna uppsats har varit att beskriva vilka faktorer som bedöms vara verksamma i terapier med unga vuxna, enligt de unga vuxna själva. Analysmetoden har varit kvalitativ innehållsanalys. Semistrukturerade intervjuer har gjorts med åtta unga vuxna med erfarenhet av att genomgå psykologisk behandling på ungdomsmottagning eller i vuxenpsykiatrin. Informanterna var mellan arton och tjugosex

This thesis investigates the interpretation of metaphorical expressions in Dante’s famous Inferno and how this may be motivated through the use of codes and inference. Based on Coseriu’s Integral Linguistics (Coseriu, 1985), metaphorical expressions can be divided depending on the kind of knowledge that is required to interpret them. The first level is the universal level where metaphors can be in

Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. In particular, scientific research is very active to find technologies that increase the efficiency of the solar cells, or decrease their cost. Reducin

Detta arbete undersöker möjligheterna för att medge upphovspersonen droit d'acces och skydd mot förstörelse inom svenska rättsförhållanden. Undersökningen inriktas främst på gällande svensk rätt vilken tolkas utifrån dess förarbeten och genom dessa Bernkonventionen. Vidare utblickar görs till Norges och Förenta Staternas lagstiftning vilken beaktas i förhållanden till en möjlig lösning av den This thesis examines the possibilities of granting the author droit d'acces and protection against destruction within Swedish copyright law. The inquiry is primarily directed toward current Swedish legislation which is construed through preparatory documents and through these the Berne Convention. Foreign legislation from Norway and the United States is examined, which are considered with refe

Given a topological dynamical system Sigma = (X, sigma), where X is a compact Hausdorff space and a a homeomorphism of X, we introduce the Banach *-algebra crossed product l(1) (E) most naturally associated with Sigma and initiate its study. It has a richer structure than its well investigated C*-envelope, as becomes evident from the possible existence of non-self-adjoint closed ideals. We link it

Organometallic analogs of chloroquine (CQ) are of interest as drug candidates that may be able to overcome the widespread chloroquine resistance developed by malaria parasites. Two new chromium arene CQ-analogs: [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylamino-methylbenzyl)-ethane-1,2-diamine]tricarbonylchromium 4 and [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylaminobenzyl)-ethane-1,2-diamine

In this paper, we consider both algebraic crossed products of commutative complex algebras A with the integers under an automorphism of A, and Banach algebra crossed products of commutative C (*)-algebras A with the integers under an automorphism of A. We investigate, in particular, connections between algebraic properties of these crossed products and topological properties of naturally associate

Laminar burning velocities of acetone + air mixtures at initial gas mixture temperatures of 298, 318, 338 and 358 K are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm, and laminar burning velocities were determined using the heat flux method, at conditions where the net heat loss from the flame to the burner is zero. The overall accuracy of the burning velocit

Imaging and inverse scattering of seismic reflection data can be formulated in terms of a certain class of Fourier integral operators. We present an approximation and discretization of such operators following a multiscale approach, based on wave packets as the quanta for representing seismic data. One of the key ingredients in our approach is the coupling of dyadic parabolic decomposition and pro

ABSTRACT Radioimmunotherapy (RIT) consists of using monoclonal antibodies (mAbs) recognizing tumor-selective antigens, as carriers of cytotoxic radionuclides to tumor tissue. RIT has been effective in lymphoma but less successful in solid tumors. mAbs slowly diffuse from the vasculature into and through solid tumors, resulting in slow, limited accretion of antibodies. The outcome is a low tumor-to

Kultursemiotiken per se analyserar mötet mellan kulturer. Begrepp som ego-kultur, extrakultur och icke-kultur är centrala i undersökningar som syftar till att blottlägga den självbild en kultur gör av sig själv i mötet med en annan. Dessa begrepp har paralleller på individnivå med de personliga pronomina i språket. I den uppsats jag ämnar presentera kommer jag därför att koncentrera mig på en disk
