High-temperature catalytic processes such as partial oxidation of Methane (POX) and steam Methane reforming (SMR) may benefit from use of reactor systems using monolithic honeycomb structures. Hereby, process performance is enhanced through more efficient heat transfer and considerable smaller reactor foot-prints than for conventional reactor concepts. Compact ceramic heat exchange structures may

The project “3D-Digging at Çatalhöyük” started in 2009 as an on-site digital experiment to record every phase of the archaeological excavation in 3D, using different technologies such as terrestrial laser scanning (TLS), image-based modeling (IBM), remote sensing, and photogrammetry. The end goal of the project is to make the excavation process virtually reversible using different simulation envir

Recently, internal combustion engine design has been moving towards downsized, more efficient engines. One key in designing a more efficient engine is the control of heat losses, i.e., improvements of the thermodynamic cycle. Therefore, there is increasing interest in examining and documenting the heat transfer process of an internal combustion engine. A heavy-duty diesel engine was modeled with a

Objective: Serine protease inhibitors (serpins), the acute phase reactants and regulators of the proteolytic processing of proteins, have been recognized as potential contributors to the pathogenesis of Alzheimer disease (AD). We measured plasma and CSF levels of serpins in controls and patients with dementia. Methods: Using rocket immunoelectrophoresis, ELISA, and Luminex xMAP technology, we anal

According to Jon Elster, mechanisms are frequently occurring and easily recognizable causal patterns that are triggered under generally unknown conditions or with indeterminate consequences. In the absence of laws, moreover, mechanisms provide explanations. In this paper I argue that Elster’s view has difficulties with progressing knowledge. Normally, filling in the causal picture without revising

Popular Abstract in Swedish I avhandlingen presenteras en teori om social makt, baserad på nya utvecklingar inom fältet social ontologi. Jag argumenterar för att en begreppsanalys av social makt kan berikas genom att dra nytta av resultaten inom social ontologi, men även att detta fält kan berikas, och faktiskt kräver, en analys av maktbegreppet. Social makt beror på existensen av andra sociala fThis work presents an account of social power based on recent advances in social ontology. It is argued that a conceptual analysis of social power can be informed by developments in social ontology, but also that this field can be enriched, and in fact requires, an analysis of this central social concept. Social power is dependent on the existence of various kinds of social phenomena, such as ins

Popular Abstract in Swedish Ett av dagens stora miljöproblem är de höga halter av koldioxid som ackumuleras i atmosfären. En stor del av samhällets koldioxidutsläpp kommer från förbränning av fossila bränslen som kol, olja eller bensin. Ett av de mest lovande alternativa bränslen som kan ersätta dagens stora bensinförbrukning är bioetanol. Cellulosainnehållande restprodukter från skogsbruk (t.ex. Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol. This thesis contains studies with the aim to improve the enzymatic hydrolysis of cellulose from steam pretreated spru

Popular Abstract in Swedish Nya möjligheter att förutsäga sjukdomsutvecklingen vid tidig ledgångsreumatism. I denna avhandling presenteras resultaten från sex studier av patienter med tidig reumatoid artrit (RA) – ledgångsreumatism. Syftet med avhandlingen var att i det tidiga sjukdomsskedet, så snart som möjligt efter diagnos, försöka skaffa information om hur sjukdomen kommer att utvecklas - om Objective: To investigate the role of magnetic resonance imaging (MRI), assessment of bone mineral density (BMD) and antibodies to citrullinated proteins (anti-CCP) in predicting radiologic outcome in patients with early rheumatoid arthritis (RA). Patients: All patients were included in the BARFOT programme (baseline). The patients had rheumatoid arthritis of recent onset with mean disease duratio

The article analyses the narrative structures in which the Holocaust has been situated in Russian historical culture.

Gifts have been given and received in all eras and societies; gifts are part of a universal human exchange. The importance of creating and sustaining social bonds with the help of gifts is widely acknowledged by social scientists, not only from anthropological but also from economic, sociological, and political science perspectives. Contemporary anti-corruption campaigns, however, have gifts to be
