Popular Abstract in Swedish Det finns en rad situationer då celler, företrädesvis nervceller, i hjärnan dör till följd av en kraftigt begränsad eller helt förhindrad blodtillförsel sk. ischemi. Till dessa hör "Stroke" eller slaganfall. Skallskada, drunkningsolyckor eller hjärtstopp med återupplivning, och hypoglykemi vid insulinkoma är ytterligare några fall där energi- eller syrgastillförseln är Mechanisms of Mitochondria-Induced Brain Damage Following Ischemia and Hypoglycemia Following prolonged disruption of blood flow to the central nervous system (CNS), or energy deprivation by other means, such as hypoglycemia, some cells will inevitably degenerate. It has been, and still is, the subject of considerable debate and intense research on brain ischemia, as to the mode of cell death, i.

Net paper readers have been shown to read deeper into articles than newspaper readers. It has also been claimed that newspaper readers rather scan than read newspapers. Do these findings mean that net paper readers read proportionally more than newspaper readers? This paper presents results showing that in fact net paper readers scan more and read less than newspaper readers. We furthermore invest

DNA-dependent protein kinase (DNA-PK) is a holoenzyme consisting of a regulatory subunit, the heterodimeric Ku70/86, and a catalytic subunit known as DNA-dependent protein kinase catalytic subunit (DNA-PKcs). DNA-PK takes part in a number of cellular functions including growth control, immunoglobulin gene rearrangement and DNA repair. The Ku86 subunit of DNA-PK has been reported to exist in human

Sweden is part of a small European minority in the perceived societal gain of PPP. After a pilot PPP project in late 1990’s no additional project has been started in Sweden. Although there is interest from both public infrastructure clients and construction companies the national government has very clearly stated that infrastructure projects should be procured in a traditional way where all fundi

Popular Abstract in Swedish Ämnet för denna avhandling är luftkvalitet i stadsmiljöer. Efter det att utsläppen till luft från industrier och produktion av värme och kraft har minskat betydligt över de senaste årtiondena framstår trafiken alltmer som en dominerande källa till luftföroreningar i städer, och utgör ett hot mot människors hälsa. De största hälsoeffekterna orsakade av trafikens utsläppUltrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. After release into the atmosphere, the particles are subjected to complex dilution and transformation processes that are of

Föreliggande litteraturundersökning om integrerade säkerhetssystem i fordon visar att system som funnits ha en positiv trafiksäkerhetseffekt är: Adaptiv farthållare, Alkolås, Automatisk lagring av färddata (svarta lådan), Antisladdsystem, Bältespåminnare, Däcklufttryckskontroll, e-Call, Hastighetsanpassare (ISA), Kollisionsvarningssystem och Körfältsstöd. System som kan ge både positiva och negati

In this paper, we confirm that angle and polarization diversities are indeed the dominant diversity mechanisms of a recently proposed compact six-port MIMO antenna array, as it exhibits similar effective degree-of-freedom (EDOF) performance as that of the ideal array with co-located antenna elements evaluated in propagation scenarios with different angular spreads. Furthermore, the same approach c
