Popular Abstract in Swedish En studie av hur glokokortikoider hämmar inflammation Glukokortikosteroider, varav kortison är den mest kända, är hormoner som reglerar många funktioner i kroppen och även används som läkemedel för att dämpa inflammatoriska tillstånd som t.ex. astma och reumatiska sjukdomar. Glukokortikosteroider är mycket potenta läkemedel och används flitigt med mycket goda effekter.The aim of this investigation has been to study mechanisms by which glucocorticoids inhibit inflammatory processes in vitro. Type IV cytosolic 85 kDa phospholipase A2 (cPLA2) is an important modulator of inflammatory responses that is present in macrophages as well as in other cell types. In macrophages, the synthetic glucocorticoid dexamethasone (dex) was found to reduce the expression of cPLA2 a

Syftet med denna undersökning var att bestämma en 1 kg isvästs kylverkan på kroppen vid brandmansarbete. Testerna genomfördes i en klimatkammare, i en container med extrem strålningsvärme och i ett rökdykningshus med värme och tungt arbete. Den faktiska kylverkan mättes också med en termisk docka. Fyra erfarna brandmän deltog i försöken. I alla tester bar försökspersonerna standardklädsel för branThe aim of the present study was to examine the effects of wearing a light-weight ice-vest (1kg, water) on physiological and subjective responses in fire fighter’s work. The experiments were carried out in a climatic chamber, in a container under extreme radiant heat, and during simulated smoke-diving. In addition, the physical cooling effect of the ice-vest was measured with a thermal mannequin.

Defining, prioritizing, and selecting requirements are problems of tremendous importance. In this paper, a new approach called Quantitative WinWin for decision support in requirements negotiation is studied. The difference to Boehm's WinWin groupware-based negotiation support is the inclusion of quantitative methods as a backbone for better and more objective decisions. Like Boehm's original WinWi

In this thesis I have summarised my work on the analysis and improvement of xylose utilisation by recombinant S. cerevisiae. A metabolic flux model was developed and used to analyse the intracellular fluxes in the recombinant xylose utilising S. cerevisiae TMB 3001 cultivated in chemostat at various dilution rates and xylose/glucose concentrations. Xylose uptake increased with xylose concentration

We propose an integrated framework for the design of SOC test solutions, which includes a set of algorithms for early design space exploration as well as extensive optimization for the final solution. The framework deals with test scheduling, test access mechanism design, test sets selection, and test resource placement. Our approach minimizes the test application time and the cost of the test acc

Limitations on the scattering matrix are derived for a wide class of objects, restricting their broadband interaction with electromagnetic vector spherical waves in terms of their size, shape and static material properties. In particular, it is seen that the order of the dominating term for electrically small objects increases with the order of the spherical wave. The results are applicable to man

Recent analyses have questioned the usefulness of heterozygosity estimates as measures of the inbreeding coefficient (f ), a finding that may have dramatic consequences for the management of endangered populations. We confirm that f and heterozygosity is poorly correlated in a wild and highly inbred wolf population. Yet, our data show that for each level of f, it was the most heterozygous wolves t

A 50-MS/s two-step flash-ΔΣ time-to-digital converter (TDC) using a 2-channel time-interleaved time-domain register with an implicit adder/subtractor demonstrates a 3rd order noise-shaping. The TDC is fabricated in 40-nm CMOS and consumes 1.2 mA from a 1.1 V supply. At frequencies below 1.25 MHz, the TDC error integrates to 103 fsrms, which is equal to an equivalent resolution of 1.6 ps.

Contesting Kurdish Identities in Sweden explores how young Kurdish immigrants living in Sweden experience and articulate their ideas about citizenship rights, belonging, and statehood as they are shuttled between different citizenship regimes and exclusive structures of belonging. Unlike immigrants who come to Sweden from countries where their groups are dominant, Kurds who immigrate to Sweden re-

Emerging wireless sensor and actuator network (WSAN) technology has the potential to enable semi-autonomous air-flow control to improve the aerodynamic performance of aircraft. In this paper, a WSAN topology comprising of multiple linear sensor clusters terminated by actuators is proposed for active flow control. Two interference aware convergecast scheduling strategies are presented and analyzed,
