We have investigated the C-60 monolayer on Al(l 10) with angle-dependent photoelectron spectroscopy. We find that orbital components have different angular distributions. Calculations of cross sections of the highest occupied molecular orbital components for free, oriented C-60 are found to describe the experimental data quite well. The observed band splitting is attributed to intramolecular elect
The reaction mechanism for the selective catalytic oxidation of ammonia to give nitrogen on CuO/Al2O3, Pt/Al2O3 and Pt/CuO/Al2O3 was investigated using transient experiments. Temperature-programmed desorption and reaction of adsorbed ammonia indicated the formation of NHx species at the surface, and that this species is the precursor for the formation of nitrogen and nitrogen oxides. Pt/CuO/Al2O3
The differential alterations of the spliceosomal UsnRNAs (U1, U2, U4, U5, and U6) were reported to be associated with cellular proliferation and development. The attempt was made in this study to analyze the metabolic pattern of the spliceosomal UsnRNAs during the development of pre-malignant lung lesions induced in experimental mice model system by benzo(a)pyrene (BP) and also to see how tea poly
In systemic radiation therapy, the absorbed dose distribution must be calculated from the individual activity distribution. A computer code has been developed for the conversion of an arbitrary activity distribution to a 3-D absorbed dose distribution. The activity distribution can be described either analytically or as a voxel based distribution, which comes from a SPECT acquisition. Decay points
Reflections on Danish and Scandinavian church archaeology focusing on three turningpoints, where new perspectives are introduced: Around 1950, 1980 and 2000. Implicit three periods are presented in the history of church archaeology, 1950-80, 1980-2000, and after 2000. The new perspectives are followed by new ways of illustrating the churches.
The research described in this thesis, focuses on some activities on the demand side that could reduce peak load in electricity system by using consumer flexibility i.e. by increasing the demand side response to signals coming from the energy market. The major objective is to test and analyse different strategies to reduce peak load at the demand side considering their techno-economic, environment
Attosecond pulse emission using a laser field with time-dependent ellipticity is studied experimentally and theoretically. Our theoretical approach is validated by comparison with experimental VUV spectra. We show in calculations that the VUV emission can be confined into a narrow temporal window in which the fundamental polarization is quasi-linear. We find an analytical equation describing the d
In this work, the interfacing of a poly(ethylene glycol) (PEG)-phosphate aqueous two-phase system with hydrophobic interaction chromatography (HIC) for primary recovery of an intracellular protein was evaluated. As a model protein, a recombinant cutinase furnished with a tryptophan-proline (WP) peptide tag was used and produced intracellularly in Escherichia coli (E. coli). E. coli cell homogenate
Murine monoclonal antibodies against the major cysteine proteinase inhibitors of human biological fluids, cystatin C and kininogen, were produced. The cystatin C antibody, HCC3, with a Ka of 2times107 l/mol, increased the inhibition of papain by cystatin C and was suitable for use in immunoblotting, immunohistochemistry and in the construction of a sensitive sandwich enzyme immunoassay for quantif
Directed and elliptic flow of inclusive photons near mid-rapidity in 158 A GeV Pb + Pb collisions has been studied. The data have been obtained with the photon spectrometer LEDA of the WA98 experiment at the CERN SPS. The flow strength has been measured for various centralities as a function of p(T) and rapidity over 0. 18 < p(T) < 1.5 GeV/c and 2.3 < y < 2.9. The angular anisotropy has been studi
Lipids from spinach thylakoids were extracted with chloroform/methanol and separated from pigments in a single chromatographic step run at 5 degrees C using silicic acid adjusted to pH 8. The isolated lipid fraction contained essentially the same amounts of individual lipids as in the initial extract. It contained less than 0.1% of the initial chlorophylls and carotenoids.
Surgery for Hirschsprung's disease is often complicated by post-operative bowel motility disorders. The impact of intestinal neural histology on the surgical outcome has been previously studied, but no information is available concerning the influence of the distribution of interstitial cells of Cajal (ICC) on these complications. These cells are considered to be pacemakers in the gastrointestinal
Teeth, jawbone fragments and vertebrae of an unusual mosasaurine mosasaur, Dollosaurns, have been collected from marine strata of latest early Campanian age in the Kristianstad Basin, southern Sweden. This material enables a detailed analysis of dental and vertebral characters, which, in turn, are used to tentatively distinguish Dollosaurus from the closely related globidensine Prognathodon. Howev
OBJECTIVE AND BACKGROUND: To investigate the CSF levels of tau and the light neurofilament protein (NFL) in patients with frontotemporal dementia (FTD) and other common dementia disorders as well as normal control subjects. Both proteins have been implicated in the pathophysiology of FTD. METHODS: CSF levels of tau and NFL were investigated in 18 patients with FTD, 21 patients with early-onset AD
Purpose: To describe the clinical expressions, with emphasis on electrophysiological examinations, in two Swedish families with Stargardt's macular dystrophy (STGD1). Methods. Two pairs of siblings with STGD1, for whom diagnosis had been confirmed by genetic linkage to the ABCA4 gene region, were examined regarding visual acuity, kinetic perimetry, fundus photography, full-field ERG and multifocal
