Popular Abstract in Swedish Med föreliggande avhandling vill jag belysa att Chrétien de Troyes Graalsaga, till skilnad från vad de åtskilliga kritiker har påstått, inte bygger på traditionella ridderliga värden, men väl avslöjar en problematisk ideologi. Denna ideologi prövas med hjälp av V. Jouves metod, som beskrivs i hans Poétique des valeurs. Graalsagans värden analyseras ur ett dubbelt perspThis dissertation aims at showing that Chrétien de Troyes' Conte du Graal does not, as often affirmed, uphold traditional chivalrous values, but discloses a problematic ideology, mostly as a result of multiple interactions at the textual level. In order to examine ideology, Le Conte du Graal is analysed in the light of the poetics elaborated by Vincent Jouve in his Poétique des valeurs (2001). Fol

A method for determination of the accessible volume fraction in gels as function of the molecular weight of the solutes is presented. The pore-size distribution is determined by measuring the rate of diffusion of a mixture of solutes into a gel using gel filtration for separation. The solutes, of various sizes, are detected by refractive index measurements. Two marker molecules (blue dextran and g

The photoreceptor cells of the nocturnal spider Cupiennius salei were investigated by intracellular electrophysiology. (1) The responses of photoreceptor cells of posterior median (PM) and anterior median (AM) eyes to short (2 ms) light pulses showed long integration times in the dark-adapted and shorter integration times in the light-adapted state. (2) At very low light intensities, the photorece

This study is based mainly on observations and interviews accomplished on two occasions with nursing assistants employed at two group living units for older people suffering from dementia in Sweden. The interviews and observations were carried out one year apart, before and after a project that also included supervision of managers and nursing assistants. I interviewed 12 nursing assistants, 8 of

During a validation process of the Swedish Knee Arthroplasty Register (SKAR), living registered patients were sent a questionnaire to ask if they had been reoperated on. This gave an opportunity to pose a simple four-point question with respect to patient satisfaction which 95% of patients answered. We analyzed the answers of patients operated on between 1981 and 1995 and found that only 8% of the

Vortices can form when finite quantal systems are set rotating. In the limit of small particle numbers, the vortex formation in a harmonically trapped fermion system, with repulsively interacting particles, shows similarities to the corresponding boson system, with vortices entering the rotating cloud for increasing rotation. For a larger number of fermions, N greater than or similar to 15, the fe

John Ternstedt (1844-1938) var en av de relativt få svenska präster som påverkades av Tübingerteologen J. T. Beck. Dessa kortfattade anteckningar innehåller inga teologiska analyser, men ger tydliga intryck av spiritualiteten i dessa kretsar med dragning åt mystik och distans till nyevangelismen. Vi får inblickar i såväl skolelevens som lantprästens tillvaro i en tid då präst och församlingsbor va

Airway mucus is regulated by many inflammatory mediators such as ILs, TNF-alpha, EGF, PGF2 alpha, LT, and so on. Recently, the relationship between membrane ion channel and Mucus production has been under investigation. The present study aimed to examine whether AQP5 was involved in modulation of mucin expression and secretion in airway submucosal gland cells (SPC-Al). A recombinant plasmid (pShAQ

The objective of this study was to examine the possibility of measuring the growth of three white-rot fungi in soil contaminated with polycyclic aromatic hydrocarbons (PAHs), by estimating the soil levels of the phospholipid fatty acid (PLFA) 18:2ω6,9. The effect of the fungi on the PAH concentration and on the indigenous bacterial population in the soil was monitored. As shown by visual examinati

Magnetresonansundersökning med magnetfältsstyrka 3 tesla (3T-MR) ger förbättrade morfologiska och funktionella undersökningar av hjärnan jämfört med de mer vanligt förekommande MR-utrustningarna med fältstyrkan 1,5T eller lägre. Fördelarna med 3T dominerar enligt vår mening markant över vissa nackdelar som den högre fältstyrkan också medför. Kombination med ett kraftfullt gradientsystem ger optima3T MRI offers improved morphological and functional studies of the brain compared with the more commonly used field strength 1.5T. Clinical 3T MRI of the brain is beneficial for high resolution morphological imaging, MR angiography, diffusion-MRI including diffusion tensor imaging, perfusion-MRI, functional MRI (fMRI), and MR spectroscopy. The performance is enhanced by the combination with powerf

The gamma decays of high spin states in Rb-77 populated in the reaction Ca-40(Ca-40,3p) Rb-77 were studied with the EUROGAM I gamma-ray spectrometer at Daresburp Laboratory, in conjunction with the recoil mass separator. The data were used to extend or establish three positive parity and five negative parity bands in Rb-77. Levei lifetimes and sidefeeding times were then measured with the NORDBALL

The integrity of the vascular system is of prime importance for survival. Therefore, several emergency and repair systems safeguard the circulatory system. Multiple processes jointly limit vascular damage and blood loss. In this article, the authors focus on the protein C anticoagulant pathway and the role of activated protein C resistance in thrombotic disease, and they discuss the involvement in
