This thesis is concerned with two aspects of peripheral nerve injury. First the early changes in the gene expression of the dorsal root ganglion (DRG) in response to sciatic nerve injury as revealed by micro-array analysis. Second an examination of the effect of PAI-1 and amphiregulin on survival and axonal outgrowth from DRG. Based on the micro-array analysis, performed on DRG 12 h and 24 h post

In this paper we present and discuss some of the lessons learnt from the completed CoLabs.eu project within the so called R3L-initiative on European Networks of Learning Regions. In the project we made some concrete social experiments in order to “make the village a virtual campus”. We start this paper by making a general introduction to the research area and by giving the motivating background to

Popular Abstract in Swedish Kvantprickar är objekt där elektroner är instängda i en mycket liten volym (av storleksordningen 100 nanometer i varje riktning). I den här avhandlingen har vi studerat kvantprickar definierade i nanotrådar av halvledarmaterial. Nanotrådarna kan vara flera mikrometer långa men samtidigt mycket tunna (mindre än 100 nanometer eller 0,1 mikrometer). Vi har skapat kvantpriThis thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. By fitting the data, we find the nanowire mean-free path to be 50 nm and the phase-cohe

Using two epochs of observations with HST/WFPC2 we obtain the stellar proper motions for all stars in the field. The proper motion are used to separate the bulge from the cluster stars. The stellar sequences in the resulting colour-magnitude diagram (CMD) are better defined than in any previously published CMD. Using a-enhanced stellar isochrones we find NGC 6528 to have a probable age of 11 +/- 2

Popular Abstract in Swedish Denna avhandling beskriver arbetet med att ta fram ett avgasreningssystem för att minska mängderna kväveoxider, NOx, som lastbilstrafik ger upphov till. Kväveoxid (NO) och kvävedioxid (NO2) i en godtycklig blandning brukar betecknas som NOx. NOx bildas vid i stort sett all förbränning, t.ex. i kraftverk eller fordon, och om avgaserna inte renas följer kväveoxiderna med The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. Many advantageous features of the diesel engine, such as life span, reliability and efficiency, make the engine the most frequent pow

The Death of Sacred Texts draws attention to a much neglected topic in the study of sacred texts: the religious and ritual attitudes towards texts which have become old and damaged and can no longer be used for reading practices or in religious worship. This book approaches religious texts and scriptures by focusing on their physical properties and the dynamic interactions of devices and habits th
