Popular Abstract in Swedish Är ledgångsreumatism en immunreaktion mot brosk? Kroppens immunförsvar bygger på ett antal olika vita blodkroppar, immunceller, som cirkulerar i blod och lymfa på spaning efter främmande och farliga "angrepp". Immuncellerna sägs svara på "angrepp", sådana immunsvar dirigeras av s k T-hjälparceller (Th-celler). Th-cellerna kommer från benmärgen, men de blir inte funktioThis thesis is based on work trying to understand the normal and pathological interactions taking place between the immune system and cartilage, specifically involving the cartilage-specific protein typ II collagen (CII). The work has been carried out in an experimental model of rheumatoid arthritis namely collagen type II induced arthritis (CIA) in mice. CIA can be triggered in mice of certain MH

The paper presents the emerging field of integrated control and CPU-time scheduling, where more general scheduling models and methods that better suit the needs of control systems are developed. This creates possibilities for dynamic and flexible integrated control and scheduling frameworks, where the control design methodology takes the availability of computing resources into account during desi

In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c

The chapter introduces the overriding question of the volume—whether poor countries can catch up—by providing an overview of theories and approaches that have contributed to this discussion. It argues for the importance of introducing to the analysis the role of structural transformation and to acknowledge that the conditions for economic development vary from case to case. Instead of clinging on

Popular Abstract in Swedish Immunsystemet är vårt skydd mot främmande organismer såsom bakterier och virus. När vi får en förkylning, eller en infektion, tar immunsystemets celler hand om och dödar de invaderade mikroorganismerna. I normala fall märker vi endast av detta i form av att vi känner oss sjuka med eventuell feber som följd. Det ställs stora krav på immunsystemet. Det ska inte bara kunnaCollagen-induced arthritis (CIA) and pristane-induced arthritis (PIA) are animal models for human rheumatoid arthritis (RA), and can be induced in susceptible mouse and rat strains. CIA is induced by immunization of type II collagen (CII), a cartilage specific protein together with Freund’s adjuvant. PIA is induced by intradermal injection of pristane (2,6,10,14-tetrametylpentadecane). In rats, in

I will start out with an overview of common assumptions on the impact of free trade on the environment – assumptions which, very much like the first part of Lamy’s statement, are all-encompassing and deterministic. From there, I will narrow down the scope of examination to specific and immediate hardware-to-hardware impacts: akin to the second part of the above statement, the emphasis shall be put

The composition of the labour force is an important economic factor for a country. Often the changes in proportions of different groups are of interest. In this paper we study a monthly compositional time series from the Swedish Labour Force Survey from 1994 to 2005. Three models are studied: the ILR-transformed series, the ILR-transformation of the compositional differenced series of order 1, and

RFID technology can improve inventory and pipeline visibility. However, there is scarce research on how to tactically and operationally make use of RFID-captured data. The purpose of this paper is thus to explore the advantages and characteristics, from a material control perspective, of keeping track of goods in real time in a supply chain. A framework regarding the potential gains of tracking u

Proton scattering has been applied to the problem of elemental quantitative analysis of air particulate matter. Elements up through chlorine may be resolved using 16 MeV protons incident upon targets up to about 1 mg/cm2 in thickness. Using the FSU Super FM Tandem Accelerator and a large area solid state proton detector, an analysis can be performed in several minutes. Combination of this techniqu

SOFC systems, working at high temperatures of about 800°C, have recently attracted significant interests for application as automotive and stationary power supply systems. This paper explores the possibilities and limitations for achievement of solid oxide fuel cells (SOFCs) as 7 kW auxiliary power units on luxury passenger vehicles operating on diesel fuel. Various issues are discussed, e.g., the

Today’s multimedia systems use different types of media with different play-out devices. Currently we are heading towards a situation where for example cellular content providers, the home entertainment industry and networked multimedia over the Internet provide different content and dirferent formats that are incompatible with devices from the other systems. This is in stark contrast with the cur

The influential role of Wnt5a in tumor progression underscores the requirement for developing molecules that can target Wnt5a-mediated cellular responses. In the aggressive skin cancer, melanoma, elevated Wnt5a expression promotes cell motility and drives metastasis. Two approaches can be used to counteract these effects: inhibition of Wnt5a expression or direct blockade of Wnt5a signaling. We hav
