Popular Abstract in Swedish Blodkärlen har till uppgift att distribuera syre och näring till kroppens alla celler, samt att borttransportera slaggprodukter som sedan bildas efter nyttjandet. Dessutom förmedlas en rad signalsubstanser till kroppens vävnader via blodcirkulationen. Eftersom mängden cirkulerande blod är begränsad är det viktigt att blodkärlen, bestående av artärer som för blodet från This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen. Treatment with antisense oligodeoxynucleotides to the ET-A receptor mRNA during organ cu

Popular Abstract in Swedish Människan har under mycket lång tid använt enzymer vid tillverkning av livsmedel, bland annat vid syrning av mjölk, jäsning av bröd och bryggning av öl och vin. Man använde sig då av hela levande organismer och först på slutet av 1800-talet kunde den aktiva substansen isoleras. Dessa aktiva substanser fick samlingsnamnet enzym, vilket kommer från grekiska och betyder "iThe influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. The improved selectivity was observed as higher synthetic yields in a-chymotrypsin and subtilisin catalyzed peptide synthesis respectively, and as higher enantioselectivity in the asymmetric reduction of ketones cat

Ethnography of Archaeology is a new but fast growing field of interest and approach, investigating the practice and materiality of professional archaeology. Often the focus is on archaeological fieldwork, as the present volume illustrates. This contribution addresses the question of what kind of experience project members have on an archaeological excavation project. Besides the way a project can

Drawing on a combination of empirical industry observations and management literature, this document at- tempts to shed some light on the usage of the term ‘convergence’ that can be identified within the security sector. The aim is to provide both a typology of definitions and a discussion of some of the strategic implica- tions of different types of convergence. A basic distinction is made betwee

Different theories have changed the way we address to technol-ogy. In the debate on the core of Information System (IS), El Sawy identi-fied three faces of IS views: connection, immersion, and fusion. El Sawy contends that it may be time for a natural shift of emphasis from the con-nection view to the immersion view to the fusion view as IT continues to morph and augment its capabilities. In the f

In wanting to pursue critically informed research, we highlight a steppingstone we use in our struggle answering the question ‘How do we recognize what to critically reflect upon?’. When we, as researchers, try to apply critical thinking we may find that our descriptions of our reasoning undermine the purpose for those descriptions. We perceive problems to flow from an entrapment of mind in the ‘f

This article investigates the historical development and transformation of Swedish integration policy, including its predecessor immigrant policy, as a “biopolitics of the population”. “Biopolitics of the population” refers in this article to all governmental interventions targeting the population, or parts of it, with a view to producing a collective body of a particular quality and identity. Swe

Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

Popular Abstract in Swedish Inom växtriket finns det ca 3000 arter som är parasitiska och dessa växer i nästan alla större ekosystem på land. Parasitiska växter kan delas in på olika sätt, helparasiter respektive halvparasiter. Denna indelning baserar sig på om de saknar klorofyll och tar all sin näring från sin värdväxt (helparasiter) eller har klorofyll och kan själva framställa kolhydrater men Parasitic plants are found in nearly every major terrestrial ecosystem and can be divided into two groups, holoparasites (lacking chlorophyll) and hemiparasites (chlorophyllous). The host-parasite connection is either situated above (stem parasites) or below ground (root parasites). In this thesis I examine the host-parasite interactions, host range and selection, and population dynamics of four r

Starch and cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution and properties is important in order to design modification processes so as to produce derivatives with the desired properties. This thesis describes research on analytical methods for the determination of the distri

119 volumes of early printed sermons (incunabula) reproduced in full on microfiche. Most of the sermons are in Latin, but some are in the European vernaculars (English, High German, Low German, French, Spanish).

The force-velocity relation of the rat portal vein has been studied during regular spontaneous contractions induced by elevated levels of [K-+]O AND [Ca-2+]o. No satisfactory description of the force-velocity relation was obtained by measuring shortening velocity in afterloaded isotonic contractions. Therefore the method of isotonic quick release was used, as this permits mechanical studies at spe

The Rio Artiguas basin in central Nicaragua shows a distinctive case of environmental deterioration due to anthropogenic activities. Heavy metals used in gold mining and other wastes are continuously released into the rivers, representing a threat to the water quality. This article aims to evaluate the groundwater intrinsic vulnerability in the Rio Artiguas basin and to provide information for sus
