The move towards the liberalisation of the energy markets in the whole world and the general shift from command-and-control to market mechanisms bring forward new ways of stimulating initiatives to increase the efficiency in the final uses of energy and demand-side management. In the past, energy policies were implemented in most countries by direct action of the governments through state monopoli
Extended abstract Recent studies point at significant and ongoing technology induced changes in the retail landscape, creating new and interesting research avenues, new managerial challenges and a need to rethink existing business models (e.g., Burt and Sparks 2003; Kollmann et al., 2012; Sorescu et al., 2011). This paper aims at contributing to the literature concerning the managerial aspects th
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
