We present experiments on field-free molecular alignment of N-2 and CO2 probed with short XUV pulses that are obtained via high-harmonic generation. The XUV pulses induce a dissociative ionization or a Coulomb explosion of the molecule, where the fragment ion recoil (measured using the velocity map imaging technique) provides information on the alignment of the parent molecule at the time of ioniz
Time-resolved photo luminescence spectra measured in solid films of two polythiophene derivatives with different chain packing allow to distinguish emission of intra-chain excitations from the luminescence of inter-chain aggregates. Aggregate luminescence is red shifted by about 0.1 eV relative to intra-chain emission and shows vibronic coupling to the C=C bond stretch with the Huang-Phys factor o
Caveolin- 1 ( Cav- 1) is essential for the morphology of membrane caveolae and exerts a negative influence on a number of signaling systems, including nitric oxide ( NO) production and activity of the MAP kinase cascade. In the vascular system, ablation of caveolin- 1 may thus be expected to cause arterial dilatation and increased vessel wall mass ( remodeling). This was tested in Cav- 1 knockout
Objective: The aim was to investigate the role that municipalities and out-patient health care centres (HCCs) have in understanding adherence to official guidelines on statin prescribing. Our hypothesis was that after guideline publication, adherence to recommended statin prescription would increase and variance among HCCs and municipalities would decrease. Since multi-level regression analysis (M
The identification of unknown genomic flanking DNA sequences can be used for the molecular monitoring of retro-, lenti- and foamyviral integration, transgenes in early embryogenesis, insertional mutagenesis, cell fate, and stem cell plasticity. Most existing methods reflect shortcomings in sensitivity and or specificity, thus limiting genomic sequencing of unknown flanking DNA to clonal preparatio
Objective. CHEK2* 1100delC is a frame-shifting germ-line mutation which abolishes the function of cell-cycle-checkpoint kinase 2 (chk2) and hence impairs the cells' response to DNA damage. This variant occurs in approximate to 1% of the general Western population but has been reported to be more common among patients with breast and prostate cancer. The aim of this study was to investigate the sig
We show that the undular stray light, diffusely scattered by the optical system of a synchrotron beamline, can play an important role in the formation of high-resolution resonant photoelectron (RPE) spectra. The influence of the stray light is mediated through the Stokes doubling effect, with the Lorentzian tail of the spectral function being replaced by a more complicated form. This effect is sho
This paper presents a method to relax Dynamic Programming. The methodmakes it possible to findsuboptimal solutions with known error bounds to hard problems.The bounds are chosen by the user, who can then effectively trade-offbetween solution time and accuracy. Several examples from differentdomains where the method is highly useful are presented.
To determine the functions of fibromodulin (Fmod), a small leucine-rich keratan sulfate proteoglycan in tooth formation, we investigated the distribution of Fmod in dental tissues by immunohistochemistry and characterized the dental phenotype of 1-day-old Fmod-deficient mice using light and transmission electron microscopy. Immunohistochemistry was also used to compare the relative protein express
Popular Abstract in Danish Med udgangspunkt i et kompetenceudviklingsprojekt for lærere i en svensk kommune adresserer denne afhandling de stigende krav til forandring og innovation, der karakteriserer den offentlige sektor generelt. Ved at følge kompetenceudviklingsprojektet gennem en fire-årig periode sættes projektet i en kontekst af innovation, globalisering og forandring. Forfatteren argumentThis dissertation critically analyses the discourse on educational change. By placing educational change in the context of globalisation and innovation the author argues that the current discourse on educational change is un-nuanced and omits the important perspectives on change. The author has analysed an educational district in Sweden and one of its projects on competence development, named 'Str
Rationale: As support in leading a meaningful and active life, a person with mental illness is often given the opportunity to attend a day centre. However, few studies have investigated the meaningfulness perceived by the person visiting a day centre. For such a purpose, a self-report instrument was developed. Aims: To explore whether perceived meaningfulness, as expressed in the recently develope
Thermal manikins are useful tools to study the clothing comfort and environmental ergonomics. The simulation of sweating can be achieved by putting a highly wicking stretchable knit fabric “skin” on top of the manikin. However, the addition of such a fabric skin makes it is difficult to accurately measure the skin surface temperature. Moreover, it takes considerable amount of time to measure the f
Objective: To investigate how first incidence of various mental disorders changed between the periods of 1947-1972 to 1972-1997 in the Lundby cohort. Method: First-incidence rates of mental disorders were calculated for two 25 year periods and ten 5 year periods. Results: From 1947-1972 to 1972-1997 a decrease in almost all age- and sex-specific incidences of neurotic and organic brain disorders w
Nerve regeneration, measured as axonal outgrowth, Schwann cell migration, macrophage invasion, and neovascularisation, was compared after repair of a 15 mm gap in rats' sciatic nerves using autologous muscle grafts made acellular either by freezing and thawing or by chemical extraction. Both extracted and freeze-thawed acellular muscle grafts could be used to bridge the defect. However, axons and
The reduction of a thin surface oxide on the Rh(1 1 1) surface by CO is studied in situ by photoemission spectroscopy, scanning tunneling microscopy, and density functional theory. CO molecules are found not to adsorb on the surface oxide at a sample temperature of 100 K, in contrast to on the clean and chemisorbed oxygen covered surface. Despite this behavior, the surface oxide may still be reduc
Popular Abstract in Swedish Under de senaste 10 åren har antalet människor i Sverige som dör av akut hjärtinfarkt minskat stadigt. Den äldre befolkningen är dock växande och med ökande antal människor med fetma och typ II-diabetes, står vi inför en stor utmaning i framtiden vad gäller hantering av patienter med akut hjärtinfarkt. För att möta denna utmaning är det viktigt att öka vår förmåga att bOne of the major determinants of the final infarct size during an acute coronary occlusion is the size of the myocardium subjected to ischemia. Identification and quantification of this so-called myocardium at risk in the acute phase of ischemia has been difficult in patients with conventional methods, such as myocardial perfusion single-photon emission computed tomography (SPECT) or electrocardio
Antimicrobial peptides represent a heterogeneous group that displays multiple modes of action such as bacteriostatic, microbicidal and cytolytic properties that are sequence and concentration dependent. Life threatening infectious disease is now a worldwide crisis and treating them effectively is becoming difficult day by day, due to the emergence of antibiotic resistant strains at alarming rates.
