In order to clarify the mechanism of the selective catalytic reduction of nitric oxide with ammonia over a V2O5(WO3)/TiO2 commercial SCR catalyst, measurements were made on the reaction rate, r(NO), as a function of partial pressure of nitric oxide, P-NO, partial pressure of ammonia, P-NH3, and partial pressure of oxygen, P-O2, from 513 to 553 K under steady-state conditions. The adsorption of NO

Popular Abstract in Swedish Denna avhandling behandlar hur elektromagnetiska vågor utbreder sig i olika material. Vanligtvis antar man i elektromagnetiska problem att materialen är linjära, det vill säga om man vet att man får en viss utsignal från materialet vid en given insignal, så förväntar man sig att få två gånger så stor utsignal om man fördubblar insignalen. I avhandlingen försöker vi klarThis thesis is concerned with the propagation of transient electromagnetic waves in nonlinear media. It consists of a General Introduction and five scientific papers. The General Introduction gives a broad overview of nonlinear electromagnetic phenomena. The emphasis is on the representation of the constitutive functional modeling the material's response to electromagnetic excitation, and the met
Photosynthetic water oxidation catalyzed by Photosystem II takes place at a site that comprises a redox-active tyrosine, YZ, a tetramanganese cluster, and, in addition to its redox components, two inorganic cofactors, calcium and chloride. Recent work suggests that YZ and the metal site are intimately linked in the oxidation and deprotonation reactions of substrate water. The metal cluster stores
Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. Paper I examines the properties of a maximum likelihood method for aligning vectorcardiographic loops, with
Methods: A randomized, double-blind, active-comparator study of patients with type 2 diabetes mellitus inadequately controlled (HbA1c 6.5-8.5%) by metformin monotherapy. Patients received vildagliptin (50 mg twice daily) or glimepiride (up to 6 mg/day) added to metformin. Results: In all, 3118 patients were randomized (vildagliptin, n = 1562; glimepiride, n = 1556). From similar baseline values (7
Basing my conclusions on Mainland Scandinavian, primarily Swedish, I argue that a strict division has to be made between three concepts or dimensions of gender: formal gender, semantic gender and lexical gender. Lexical gender is a salient meaning component of a noun; this dimension of gender is syntactically inert. Semantic gender is a category of thought, conveyed by pronominal resources. Semant
For almost forty years the seemingly harmless term “postmodern” has sown discord and ruffled feathers in the intellectual world. Mere sight of the term has caused some commentators to see red in more than one sense: “postmodernism” for them embodies the utter degeneracy of the 1960s Left. For their part, more than a few commentators on the left have associated the term with the neoliberal climate
This thesis, which is based on four original papers, covers different aspects of the evolvement and development of proteomic platforms and the construction of human synthetic antibody libraries for the isolation of antibody reagents has been very central. There is an accelerating need for technologies capable of providing proteomic analysis of high sensitivity with good accuracy and an overall bro
The social dimensions of the great transformation from an agrarian to an industrial society are still poorly understood. Today there are challenging opportunities to study such processes in Asia, and to do this against a comparative background of similar transformations elsewhere, for example in Europe, and in the light of theories of social mobility, industrialisation and agrarian change. This st
Popular Abstract in Swedish Råttans urinblåsa har studerats ur olika aspekter, sedan antingen ett standardiserat avflödeshinder åstadkommits eller hälften av urinblåsans nervförsörjning avlägsnats. Avflödeshindret har åstadkommits genom att en silkestråd knutits runtom urinröret så att det försnävats. Genom att en knappt mm-vid metallstav knutits om samtidigt och sedan avlägsnats, har graden av av
Popular Abstract in Swedish Typ 2 diabetes (även kallat sockersjuka eller åldersdiabetes) är en av våra vanligaste förekommande folksjukdomar och ungefär 5% av alla människor beräknas ha sjukdomen. Typ 2 diabetes karakteriseras av kroniskt förhöjda blodsocker-nivåer som orsakas dels av en oförmåga hos insulin att befrämja blodsockerupptag i dess målvävnader, fett och muskel, och dels av en oförmågType 2 diabetes mellitus is a multifactorial disorder characterized by chronic hyperglycemia resulting from pancreatic dysfunction and insulin resistance. It is a common disorder with a complex pattern of inheritance, likely to reflect the influence of multiple genetic and environmental factors on the diabetes risk. The aim of thesis was to identify genetic risk factors for type 2 diabetes. In a g
Popular Abstract in Swedish Immunsystemet utgörs av de celler och molekyler i kroppen som har till uppgift att skydda oss mot angrepp av sjukdomsframkallande bakterier, virus och parasiter. Dessa patogener hindras först och främst av fysiska barriärer såsom hud, slemhinnor och mag/tarm kanalen. Patogener som har lyckats ta sig igenom dessa barriärer, möter härnäst immunsystemets första försvarslinThis thesis is based on work studying the immunoregulatory mechanisms that govern the balance between activation and inactivation of T lymphocytes. Most of the work has been carried out in an experimental system using a T cell receptor (TCR-Vb3) transgenic mouse strain to obtain a homogenous T-cell population and utilizing the properties of bacterial superantigens to induce T cell responses and un
Popular Abstract in Swedish Profeterna legitimerar i regel sitt budskap genom att inleda med den s k budbärarformeln: Så säger Herren. Därmed menar de att Herren talar genom dem. De utgör endast hand stämma. De budskap, som framförs under de knappt 400 år som Gamla testamentets skriftprofeter verkar, är emellertid oerhört mångformiga. Och detta gäller inte bara innehållet utan också utformning, spWhy does the Lord say thus? Prophets, Contexts, Rhetoric A Comparison Between Amos and Malachi When the prophets preached their messages they authorized their words by the old messenger formula "Thus says the Lord". The import of these words was to emphasize that the prophet was only the mouthpiece of the Lord. However, the prophetic literature of the Old Testament is highly varied in its scope a
Sverige är ett utpräglat småföretagarland och mätt i antal bedrivs en klart övervägande del av företagen som enskild näringsverksamhet. Till skillnad från aktiebolag och andra juridiska personer, som hänför alla inkomster till inkomstslaget näringsverksamhet, ska inkomster eller utgifter för fysiska personer hänföras till endera av inkomstslagen näringsverksamhet, tjänst eller kapital. AvhandlingeSweden is a typical small-business country and, based on the numbers, a clear majority of the companies operate as sole traders. Unlike limited companies and other legal entities, which classify all income as business income, the income or expenditures of private persons are classified as either business, service or capital income. The main objective of this thesis is to systematically examine the

The thesis is based on three empirical studies examining middle-aged and young old (< 70 years) non-demented patients assessed at a memory clinic. In the first study the personality characteristics of the patients were compared with a Swedish normative sample. The patients scored higher o
The post-failure convergence of the shortest path routing (SPR) protocols used in IP networks can be too slow to meet the restrictive requirements (i.e., maximum allowable delay, jitter, etc.) of the multimedia services and therefore new restoration mechanisms combined with IP routing are of interest. The paper addresses optimization of three potential rerouting mechanisms based on the IP fast rer
Popular Abstract in Swedish Proteiner är den huvudsakliga beståndsdelen i levande celler. Proteiner består av långa kedjor av aminosyror som sitter ihop med peptidbindningar och vecklar ihop sig till komplicerade tre dimensionella strukturer. Proteiner är involverade i praktiskt taget alla mekanismer och funktioner i cellen. När man studerar hela proteinsammansättningen i t.ex. ett organ, en speciMembrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. a cell or a tissue, at a certain time point and "proteomics" is the large scale study of these prote
