The Auger-Doppler effect in the experimental spectra of HF and DF is presented. and the dynamics of ultra-fast dissociation in the core-excited state are discussed. The Doppler splitting of the atomic Auger peak is calculated and simulated using a classical model and a very good agreement is found between experiment and simulation. It is shown that the difference in photon energy relative to the r
1. The dilator effect of extracellular adenosine triphosphate (ATP) has mainly been characterized as a direct effect on smooth muscle or as an endothelium-dependent effect mediated by nitric oxide (NO) or prostaglandins. We tested the hypothesis that endothelium-derived hyperpolarizing factor (EDHF) may also be involved. Dilator effects were studied in vitro by continuous recording of isomeric ten
Photon-echo-based devices have been proposed for many applications in data storage, image processing, and optical communications. Many of these applications would benefit if the output from the photon-echo process could be used as input in a second photon-echo process. We demonstrate the generation of such secondary echoes, using the amplified output from an initial photon-echo process. The amplif
This article is an overview of the various aspects characterizing the interjection - probably the most controversial linguistic unit in the history of grammatical tradition and modern linguistics - as Latin grammarians outlined them, especially in the postclassical and late antiquity. The corpus employed for the purposes of this study is Henricus Keil's Grammatici Latini, a most valuable and uniqu
Introduction of the xylose pathway from Pichia stipitis into Saccharomyces cerevisiae enables xylose utilization in recombinant S. cerevisiae. However, xylitol is a major by-product. An endogenous aldo-keto reductase, encoded by the GRE3 gene, was expressed at different levels in recombinant S. cerevisiae strains to investigate its effect on xylose utilization. In a recombinant S. cerevisiae strai
Popular Abstract in Swedish Patienter med kroniskt obstruktiv lungsjukdom, KOL, har en försämrad lungfunktion och lider av bronkit och andnöd. Dessa symptom beror troligtvis på en ständigt pågående inflammation i lungan som dels leder till ökad slemproduktion och förträngning av luftrören, dels till emfysem dvs. nedbrytning av lungvävnaden vilket försämrar gasutbytet i lungan. Cigarrettrökning är Chronic obstructive pulmonary disease, COPD, is manifested by chronic airflow limitation due to inflammation and tissue destruction in the lungs. COPD is caused primarily by smoking and with increasing cigarette consumption in the world, the prevalence for COPD will most probably increase in the future. The chronic inflammation in the lungs of these patients is thought to drive the pathogenesis fo
I föreliggande rapport redovisas en fördjupad studie av hur en vattenavvisande impregnering fungerar när det finns sprickor i fasaden.
The relation between the isoform distribution of the myosin 17 kDa essential light chain (LC17) and the mechanical properties of smooth muscle was investigated. The relative content of the basic (LC17b) and acidic (LC17a) isoelectric variants of the 17 kDa myosin light chain was determined in different mammalian smooth muscle tissues. The relative content of LC17b varied between muscles: rabbit re
New neurons are only generated in two places of the postnatal brain; the subventricular zone (SVZ) and hippocampus. The SVZ-derived cells specifically migrate to the olfactory bulb where they give rise to new interneurons. We have genetically manipulated the postnatal SVZ progenitor cells with the aim to direct them to a neuronal fate in the striatum. Our result showed that ectopic expression of t
This study aimed to investigate the presence of pain, pain duration, localization(s), intensity, type and pharmacological treatment among older adults living in sheltered accommodation or receiving rehabilitation, as well as the agreement between pain assessments performed by staff and the older adults. Twenty-nine randomly selected older adults (65+ years) and the staff who looked after them part
BACKGROUND: Previous studies have shown that short-term treatment with adrenocorticotrophic hormone (ACTH) has a strong and rapid lipid-lowering effect. In this long-term study of nephrotic patients with idiopathic membranous nephropathy, the influence of ACTH on the serum lipoprotein profile and glomerular function as well as the dose-effect relationship was investigated. METHODS: Fourteen patien
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
