Popular Abstract in Swedish Denna avhandling beskriver arbetet med att ta fram ett avgasreningssystem för att minska mängderna kväveoxider, NOx, som lastbilstrafik ger upphov till. Kväveoxid (NO) och kvävedioxid (NO2) i en godtycklig blandning brukar betecknas som NOx. NOx bildas vid i stort sett all förbränning, t.ex. i kraftverk eller fordon, och om avgaserna inte renas följer kväveoxiderna med The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. Many advantageous features of the diesel engine, such as life span, reliability and efficiency, make the engine the most frequent pow

The Death of Sacred Texts draws attention to a much neglected topic in the study of sacred texts: the religious and ritual attitudes towards texts which have become old and damaged and can no longer be used for reading practices or in religious worship. This book approaches religious texts and scriptures by focusing on their physical properties and the dynamic interactions of devices and habits th

Klimatomställning ses av många som en väg ut ur den hotande klimatkrisen. Problemet är bara att klimatomställning inte är ett entydigt begrepp, varför det i klimatdebatten förekommer olika uppfattningar om hur genomgripande samhällsförändringar som krävs för att begränsa den globala uppvärmningen. Somliga ser en radikal omställning av de ekonomiska och politiska systemen som en nödvändighet, medan

Coupled gas chromatographic (GC)–electroantennographic detection (EAD) analyses of ovipositor extract of calling Hessian fly, Mayetiola destructor, females revealed that seven compounds elicited responses from male antennae. Four of the compounds—(2S)-tridec-2-yl acetate, (2S,10Z)-10-tridecen-2-yl acetate, (2S,10E)-10- tridecen-2-yl acetate, and (2S,10E)-10-tridecen-2-ol—were identified previously

This paper presents a highly linear radio frequency receiver front-end with on-chip balun for cellular application at 2GHz in 65nm CMOS technology. Based on direct conversion architecture, the implemented front-end comprises a customized on-chip balun for single-ended to differential signal conversion, a differential common-gate low noise amplifier and voltage mode quadrature passive mixer. The si

We investigate a means of explaining the apparent paucity of red giantstars within post-core-collapse globular clusters. We propose thatcollisions between the red giants and binary systems can lead to thedestruction of some proportion of the red giant population, by eitherknocking out the core of the red giant or by forming a common envelopesystem which will lead to the dissipation of the red gian

I detta kapitel analyserar jag redovisande förklaringar av aktörernas agerande och observerade sekvenser där övervakning och social kontroll på institutionen återges och synliggörs av ungdomar med en annan etnisk bakgrund än den svenska. En utgångspunkt i analysen är Thomas Hylland Eriksens (1993/2000) syn på etnicitet som en pågående relationsprocess mellan aktörer. När etnifierad övervakning ocIn an evaluation of a juvenile-care project sponsored by the Swedish National Board of Institutional Care, ethnicity was identified as an important factor in treatment, staff practices, and relationships between juveniles. This study examined ethnic monitoring and social control in 15 Swedish juvenile institutions. I analysed notes from interviews and field observations. Discriminatory behaviours

Popular Abstract in Swedish Under fosterutvecklingen är det viktigt att alla kroppens celltyper kommer till rätt plats vid rätt tidpunkt. Det är också viktigt att cellerna mognar och delar sig under kontrollerade former. Då dessa processer inte fungerar, kan missbildningar eller cancer uppstå. Redan på embryonalt stadium börjar nervsystemet ta form. En del av nervsystemet kallas det autonoma elleNeuroblastoma is a tumor of the sympathetic nervous system, and arises during early childhood. The tumor is highly heterogeneous and evidence, such as expression of genes normally only expressed during embryonic and fetal stages, suggests that the tumor is of embryonic origin and that the tumor arises as a consequence of perturbed differentiation during the development of the sympathetic nervous s

The Swedish Higher Education Ordinance states1 in Chapter 8, section 1 (Svensk Förfat- tningssamling [SFS] 1993:100) that disciplinary action can be taken against a student who “at- tempt to deceive during examinations or when academic work is otherwise assessed”. Suspicion of such behaviour is to be reported to the disciplinary board, which in turn has to establish the students intent. The main f

Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. The two nuclei together provide the possibility to explore mirror

The subjects of this thesis are (as indicated by the title) truth, grounding and dependence. The thesis consists of an introduction and five free-standing essays. The purpose of the introduction is not merely to summarize the papers, but to provide a general background to the discussions in the essays. The introduction is divided into four chapters, each of which splits into a number of sections a
