Using a high pressure chamber, different types of lubricants have been studied at pressures representative of elastohydrodynamically lubricated contacts. The three types of lubricants (solid, liquid and gaseous) have been compressed and sheared to measure the compression, the shear stress as a function of pressure and shear velocity, and the solidification pressure. In the high pressure chamber re

Popular Abstract in Swedish Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.

Water contamination of lubricants is often considered as

Geophysical investigations using 2-D DC resistivity were carried out on old parts of two similar landfills, with waste of different ages. The data sets, which included high data density in both vertical and horizontal directions, were interpreted with 2-D smoothness constrained inversion. The landfills were excavated after the surveying. The objective was to test the capability of the resistivity

This article seeks to explore how Christian self-understanding has changed as Jewish-Christian relations have enhanced and improved during the last half-century. To what extent are traditional Christological and soteriological models and motifs discussed, defined, redefined, refined or even refuted? Three issues are discussed: the need to (a) go beyond bipolarity (Judaism vis-à-vis Christianity et

Mixed acid phospholipids are valuable compounds, which are used mainly in membrane- and lipoprotein research and in liposome technology. The chemical synthesis of these special lipids is rather difficult and involves both toxic chemicals and harsh reaction conditions, which makes the products less attractive for medical and biological applications. Enzymes in contrast catalyze chemical reactions u

Popular Abstract in Swedish Slaganfall (stroke) är en av de vanligaste orsakerna till invaliditet och död i Västvärlden. I Sverige drabbas cirka 35.000 människor varje år, 25.000 av dessa får sitt första slaganfall, och de flesta är äldre än 70 år vid sjukdomsdebuten. Slaganfall orsakas av att en begränsad del av hjärnan inte får tillräcklig syretillförsel, och detta beror antingen på att blodflödThe thesis investigated clinical, neuroimaging and prognostic features in lacunar infarction. The studies were based on a series of 100 consequtive patients with a first-ever stroke and a lacunar syndrome investigated with CT, Gd-DTPA enhanced MRI, and with respect to large vessel disease and cardioembolic sources. the patients were followed for a mean of 4 years. MRI was repeated one year after s

I år var andra gången som Lunds universitet genomförde en universitetsgemensam pedagogisk utvecklingskonferens, första gången var 2007. Konferensen, som är ett samarrangemang mellan samtliga fakulteter och CED, har nu alltså blivit en återkommande aktivitet! Samhällsvetenskapliga fakulteten stod värd för årets konferens och dekanus Ann-Katrin Bäcklund sträckte vid invigningen fram en symbolisk sta

Essän ägnas åt att skissera en möjligt utvecklingslinje för hur bilder av manskroppen skapats och/eller använts i en homosexuell kultur från sekelskiftet 1900 till idag, och hur detta bildbruk samverkat med en normaliserande och dominerande heterokultur.

Popular Abstract in Swedish Tumörer kan på olika sätt hämma immunsystemet och detta kan vara orsaken till varför immunterapi mot tumörer oftast inte lyckas. Denna nedreglering av immunförsvaret kan medieras av faktorer producerade från tumörcellerna själva eller så kan den följa efter en stark immunstimulering som satts igång av immunterapi. Kväve monoxid (NO) har visats vara en av de ämnen som kaDuring tumor progression a strong immunosuppression is developed and is believed to be the major reason why immunotherapy fails. This suppression is induced in response to factors produced from tumor cells, but can also be induced after immunotherapy. NO has been shown to play a major role in this suppression both in patients with gliomas and colon carcinomas. The aim of this thesis is to clarify
