Popular Abstract in Swedish Manniskan utsatts dagligen for sjukdomsframkallande bakterier och virus, vilka maste tas omhand och oskadliggoras. Var hud och slemhinnor fungerar som ett forsta fysiskt och biokemiskt skydd. De som tar sig forbi denna barriar angrips av vart immunforsvar. De vita blodkropparna ar de celler, som snabbast rycker ut till vart forsvar och ater upp och forstor angriparen. DT cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. Mutations in the SAg MHC class II a-chain binding site reduced the number of responding T cells expressing particular TCR Vb chains, whereas mutati

Abstract in UndeterminedObservations of chemically peculiar (CP) stars have been conducted for decades and have revealed a variety of spectrum anomalies, most prominent among them are line enhancements of heavy elements. The earlier observations were limited to the optical region and the use of less sensitive detectors, yet are responsible for much of our current characterization of the CP star ph

A business analyst who commences an investigation into design requirements for a new work system probably does not ‘label’ her inquiry process as research. However, a research perspective is needed if a productive learning spiral is to be established in which ‘useful’ systems can be created. Systematic, collaborative inquiry adopting an complex, open systems perspective is required in order to est

Bulgarian apico-alveolar stops and Swedish dorsovelar stops are palatalized when adjacent to front vowels. An X-ray motion film study of these assimilations (part of an ongoing investigation of the temporal organisation of coarticulation and assimilation) is presented. Two issues are examined, extrinsic vs intrinsic production of assimilation and feature spreading vs. coproduction. The articulator

En sådan konstgjord balans är givetvis komplicerad” Själva essensen i biologi kan sägas vara förändring. Stabilitet genom förändring – cellerna i en kropp, artpopulationerna i ett ekosystem. I 2000-talets landskap är det mesta under förändring av olika människors projekt. De områden av ”naturlig förändring” som finns är inringade; språkmässigt, lagmässigt, med staket. De områden som står utan sky

De allra flesta läkarbesöken för infektioner sker i primärvården. En hög och olämplig antibiotikaförskrivning innebär risker inte bara för biverkningar för patienten utan också för ökad antibiotikaresistens. Stora ansträngningar har gjorts för att minska antibiotikaförskrivning. Under covid-19-pandemin såg vi att antalet infektioner och antalet antibiotikaförskrivningar halverades. Hur kan vi fortThere is considerable variation in antibiotic prescribing rates among physicians, primary healthcare centres, and countries. If the variation could be reduced, the antibiotic prescribing could decrease.Methods. The thesis is based on real-world data from two databases containing infection visits: The Kronoberg Infection Database in Primary Care (infection visits in the Kronoberg region from 2006 t

En kortlek med 67 situationskort för universell utformning för lärande (UDL) utvecklades vid fyra internationella lärarworkshops för att hjälpa lärare att förstå och förbättra inkluderande undervisning, dvs. att vara proaktiva och förberedda på en mångfald av studenter. De utskrivna korten har hämtats eller beställts av cirka 150 personer. Denna artikel presenterar resultaten av en enkät som skickA deck of 67 context cards for Universal Design for Learning (UDL) was developed at four international teacher workshops, to help teachers understand and improve inclusive teaching, i.e. to be proactive and prepared for student diversity. The printed cards have been picked up or ordered by approximately 150 people. This paper presents the results of a questionnaire sent to 44 people.The results fr

We show acoustic separation of 7.8 µm from 5 µm fluorescent polystyrene particles at an unprecedented sample flowrate of almost 1000 µL/min.

During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge

This work presents an acoustofluidic chip capable of separating cells form their corresponding secretome for subsequent MALDI-MS analysis, which can be used amongst many other applications for directed evolution.

We present a non-contact platelet functional analysis platform based on acoustic trapping of platelet clusters and activation monitoring using impedance spectroscopy. The system was characterized using polystyrene particles and human platelets. The system was also capable of transferring platelets from plasma into a controlled buffer. Trapped platelets were activated using 20 and 40 μM TRAP and th

n international law, states are assumed to be persons by virtue of being bearers of rights and obligations. This chapter provides a brief genealogy of the person of the state. It shows how the concept of sovereignty — first understood as supreme and indivisible authority within a given polity — helped early modern authors to account for the temporal continuity of states, and also allowed them to a
