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

The HASTA indicator framework, covering the three dimensions of sustainability, i.e. Economic, Environmental and Social, to monitor sustainability of transport in Swedish cities was elaborated. Under the three sustainability dimensions, there are 6 sustainability aspects (indicator groups), 2-3 per dimension; these are Efficiency, Accessibility (Economic dimension), Accessibility, Safety, Liveabil

A heavy-duty diesel engine operating case producing no engine-out smoke was studied using combined simultaneous optical diagnostics. The case was close to a typical low-load modern diesel operating point without EGR. Parallels were drawn to the conceptual model by Dec and results from high-pressure combustion vessels. Optical results revealed that no soot was present in the upstream part of the je

The aim of this study was to find sorption filters with a capacity to remove heavy metals from landfill leachate. Initially a batch test was performed with granular activated carbon, CAP meal derived from animal bones, iron fines, a non-metallic part of bottom ash from a municipal solid waste incineration plant, metal residues from the same bottom ash, lime stone and peat. Activated carbon, CAP me

The hunter-gatherer groups of Southeast Asia represent a diverse range of adaptations. The so-called Negritos of the Andaman Islands, the Malay Peninsula and the Philippines have attracted particular attention because of long-standing claims that they represent traces of pre-agricultural Southeast Asia. Research on Andaman and Philippine prehistory has tended to maintain at least some components o

This thesis investigates structure-acoustic problems, which involve a flexible structure coupled to an enclosed acoustic fluid. In the literature, this type of problem is usually referred to as vibroacoustic problems or structure-acoustic problems with fluid interaction. The thesis consists of two parts. The first part provides an introduction into the field of structure-acoustic analysis withi

High resolution real time heat release analysis will become increasingly important in the future development of engine control systems. The increased demands on efficiency and emissions will put high demands on future engine control. Future engine concepts, for example the HCCI engine concept might crave cylinder pressure based Closed-Loop Combustion Control (CLCC). The analysis of cylinder pressu

A key advantage of Grid systems is the ability to share heterogeneous resources and services between traditional administrative and organizational domains. This ability enables virtual pools of resources to be created and assigned to groups of users. Resource awareness, the capability of users or user agents to have knowledge about the existence and state of resources, is required in order utilize

Popular Abstract in Swedish Huvudsyftet med min avhandling är att visa hur klass konstruerades språkligt i Svensk Damtidning i början av 1900-talet. Teoretiskt efterlyser jag en förnyelse av studier av klass, och skriver därmed in mig i de post-marxistiska och feministiska traditionerna. Ett viktigt mål på vägen är också att klarlägga dampressens status som historisk källa, inte minst genom en anaThe aim of my thesis is to demonstrate how class was constructed linguistically in Svensk Damtidning (Swedish Woman's Magazine) at the beginning of the 20th century. Theoretically, I call for a renewal of studies of class, thus joining the traditions of post-marxism and feminism. Research into language and class, strongly coloured by modernism, suggests that from the 19th century onwards people i

Popular Abstract in Swedish Den kroniska inflammation som ses hos personer med inflammatorisk tarmsjukdom är troligen en immunologisk reaktion riktad mot normala tarmbakterier. I denna process har monocyter/makrofager (särskild celltyp av vita blodkroppar) en central betydelse. Det är huvudsakligen makrofager i tarmslemhinnan som styr det immunsvar som utvecklas då tarmfloran kommer i kontakt med Inflammatory bowel disease is thought to result from the inappropriate and ongoing activation of the mucosal immune system driven by the presence of normal luminal flora. In this process monocytes/macrophages contribute to and maintain chronic inflammation by being both regulatory and effector cells. This study aimed at exploring the effects and regulation of chronic inflammation in inflammatory
