Popular Abstract in Swedish Populärvetenskaplig sammanfattning Vår arvsmassa består av tre olika typer av DNA; kodande, reglerande och ofunktionellt DNA. Det kodande DNA:t används som ritning för hur våra proteiner ska sättas ihop. Proteinerna är de stenar som bygger upp våra celler och ger dem dess specifika funktion, en hudcell är t ex uppbyggd av andra proteiner än en muskelcell. Det är viktigtThe neutrophil store its effector proteins in several distinct types of cytoplasmic granules, developed sequentially during cell maturation. The different subtypes of granules have unique protein content and functional characteristics. The formation of each granule subtype coincides with the biosynthesis of its content. Granule proteins synthesised during the formation of a granule subtype are thu

Against the deeply ingrained belief that technology is instrumental and neutral, this thesis argues that our relation to technology is inextricably bound up with fantasies. But what is the nature of these fantasies and where do we find them? Are they strictly reserved to the domain of Science Fiction, or can we also find them in more mundane contexts, like the business organization? These are som

Current-mode control can be used to control switched DC-DC power converters. This paper compares two continuous-time models for current-mode control that are made to be accurate up to half the switching frequency. The two models are the ones presented by Ridley and Tan. The closed loop frequency responses predicted by these two models are compared with results obtained from simulations of a buck c

Riter och ritual är mångsidiga fenomen vilket gör att studiet av formaliserade handlingar återfinns inom flera ämnesdiscipliner. I Den rituella människan – flervetenskapliga perspektiv visar forskare inom arkeologi, etnologi, psykologi, teatervetenskap, religionshistoria och teologi hur de har funderat över den rituella praktiken. Varför använder människan sig av riter, hur kan rit och ritual stud

Web sites are exposed to high rates of incoming requests. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. An admission control mechanism rejects some requests whenever the arriving traffic is too high and thereby maintains an acceptable load in the system. This paper presents how admission control mechanisms can be designe

Governmental organisations are becoming more critically dependant on IT systems such as communication systems or patient data systems, both for their everyday tasks and their role in crisis relief activities. Therefore it is important for the organisation to analyse the reliability of these systems as part of the organisation’s risk and vulnerability analysis process. This paper presents a practic

Lattice Boltzmann method (LBM) is a method that can be used to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the porous anode for an anode-supported Solid Oxide Fuel Cell (SOFC). The purpose of this study is to investigate the effects of electrochemical reactions on the transport processes by a 3D model at microscale. A porous 3D modeling domai

Popular Abstract in Swedish Denna avhandling beskriver tillverkning av partiklar av metaller och halvledare samt dessas användning i nya typer av elektroniska komponenter och nanostrukturer. Partiklarna tillverkas med aerosolteknik, dels med kända metoder och dels med nyutvecklade. Partiklarna är mellan 5 och 80 nanometer (miljarddels meter) i diameter, och deras bildning, struktur och sammansättnAerosol technology was used to develop new methods for fabrication of size-selected, nanometer-sized particles of metals and semiconductors. Such particles were used to realize different types of quantum devices and nanometer-sized structures. The thesis contains an introduction, five papers on particle fabrication, and five papers on particle-based quantum devices. Size-selected gallium and indi

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
