The intensities of hydrogen Lyman-α and Balmer series emission lines as a result of photoexcitation of free CH4 and NH3 molecules at the C 1s and N 1s edges have been measured. For methane, the total fluorescence yield in the visible region (300–650 nm) was also recorded. Excitation functions of the Balmer lines show relative intensity enhancement of Balmer-β emission in comparison with Balmer-α a

A modified Delphi method was used to determine thresholds for Minimum Data Set quality indicators for Icelandic nursing homes. The thresholds were then applied to quality outcomes in Icelandic nursing homes for the year 2009. The thresholds indicate areas of good or poor care and can be used for planning services. Icelandic nursing homes seem to be doing best in incontinence and nutritional care.
An ensemble of codes defined by parity-check matrices composed of M × M permutation matrices is considered. This ensemble is a subensemble of the ensemble of low-density parity-check (LDPC) codes considered by Gallager [1]. We prove that, as M → ∞, the minimum distance of almost all codes in the ensemble grows linearly with M. We also show that in several cases the asymptotic minimum-distance-to-b
Microchromatographic separations of polar aromatic compounds (pyridine, 4-pyridylmethanol, 4-methoxyphenol, 2-naphthol, catechol, hydroquinone, resorcinol, 2,7-dihydroxynaphthalene) using continuous beds are described. The columns were prepared by a simple one-step in situ polymerization procedure: a solution of acrylic monomers, including the cross-linking agent piperazine diacrylamide, was polym
Popular Abstract in Swedish Osteoartros (populärt kallat utsliten led) är ett vanligt tillstånd i höft- och knäled. Smärta, stelhet och minskade möjligheter att röra sig fritt är vanliga symtom. Att byta ut leden helt vid en operation är ett effektivt sätt att lindra patienternas besvär. Dessa operationer är vanliga i hela västvärlden och prognoser tyder på en tilltagande tendens i det årliga antaBackground: Elective knee and hip arthroplasty are common surgical procedures. Improved anaesthetic and nutritional care has the potential of increasing patient satisfaction and reducing length of hospital stay (LOS). The overall aim of this thesis was to evaluate the effect of perioperative nutrition and different anaesthetic techniques on per- and postoperative outcome after elective total hip (
Popular Abstract in Swedish Avhandlingen består av fyra artiklar som behandlar olika aspekter av vattenvågor med vorticitet. Artikel I: Symmetry of steady periodic gravity water waves with vorticity. Vi bevisar att en fortskridande, periodisk, två-dimensionell, rotationell gravitationsvåg, med en ytprofil som är monoton mellan vågdalar och vågtoppar, måste vara symmetrisk kring vågtoppen, oavseAbstract: This thesis consists of four papers related to various aspects of water waves with vorticity. Paper I: Symmetry of steady periodic gravity water waves with vorticity. We prove that steady periodic two-dimensional rotational gravity water waves with a monotone surface profile between troughs and crests have to be symmetric about the crest, irrespective of the vorticity distribution wit
Abstract The aim of this study was to investigate how people with chronic pain experience their daily doing, with a special focus on possible adjustment to pain and altered life conditions in order to cope with pain and maintain well-being. In-depth interviews were guided by themes concerning daily occupation, ways to maintain well-being, and future expectations. Using qualitative content analysis
During the last decades, image analysis has become an important tool in various applications. The increase in computer power has led to that more advances algorithms can be developed. In this thesis image analysis has been used in three different applications; quality control of asphalt, cancer detection in histopathological images and traffic surveillance. In the first part of the thesis image a
Hypoxia-dependent angiogenesis is an inherent feature of solid tumors, and a better understanding of the molecular mechanisms of hypoxic cell-death should provide additional targets for cancer therapy. Here, we show a novel role of the polyamines in endothelial cell (EC) survival during hypoxia. Polyamine depletion by specific inhibition of ornithine decarboxylase was shown to protect ECs from hyp
Lysophosphatidylcholine (LPC) has been attributed a pro-inflammatory role in atherosclerosis. Cell culture studies have identified stimulation of cytokine expression and chemotaxis by micromolar (muM) concentrations of LPC. In the present study we have investigated if LPC, in similarity with many other lipid mediators, has pro-inflammatory effects also at nanomolar (nM) concentrations. Cultured mo
PURPOSE:: We studied the effects of chronic treatment with the novel selective cannabinoid 2 receptor agonist cannabinor (Procter&Gamble Pharmaceuticals, Cincinnatti, Ohio) on bladder function in conscious rats with partial urethral obstruction and on the functional properties of isolated detrusor muscle. MATERIALS AND METHODS:: A total of 24 female Sprague-Dawley® rats with surgically created
A method for calculating energy levels and wavefunctions of bound states associated with deep impurity centres in semiconductors is presented. The impurity system is replaced by a crystal, whose unit cell consists of the impurity surrounded by a large number of host crystal atoms. The impurity bands for this crystal, represented by a real potential, are calculated by expanding in orthogonalised Bl
Let $\scr H(U)$ denote the class of analytic functions in the unit disc $U$ and $g$ be analytic in $U$, normalized by $g(0)=g'(0)-1=0$ and $g(z)\ne0$ for $z\in U\sbs\{0\}$. $H^p$, $0
