Rapporten dokumenterar ett års mätningar och utvärderar mätdata från en värmepumpcentral som förser 13 radhus i Malmö med värme och varmvatten. Värmepumpcentralen, husen samt driftserfarenheter och problem beskrivs. Reglering av stegprocesser och drift av kombinerade kollektiv behandlas.

The electronic structure and the UV- vis spectrum of reduced and oxidized model systems of the N, N'- 1,2phenylenebis( 2- mercapto- 2- methylpropionamide) copper complex have been studied using a multiconfigurational quantum chemical method ( CASSCF/ CASPT2). The bonds between Cu and the two sulfur ligand atoms have a large covalent character in the oxidized Cu( (III)) form. As a result of the inc

Objectives: The aim of this study was to review the presentation and analysis of ordinal data in three international nursing journals in 2003. Method: In total, 166 full-length articles from the 2003 editions of Cancer Nursing, Scandinavian Journal of Caring Sciences and Nursing Research were reviewed for their use of ordinal data. Results: This review showed that ordinal scales were used in abo

Three enantiomeric pairs of Diels-Alder adducts of 2,5-diphenylphosphole-1-oxide have been resolved by elution of each of the enantiomers with 95% ethanol from a swollen microcrystalline triacetylcellulose stationary phase. The degree of separation achieved in each case was confirmed by comparing the absorbance maximum of the UV spectrum of each separated enantiomer with that of a similar concentr

We evaluate a new class of rate-distortion codes based on simple linear congruential recursions. Codes are demonstrated for the memoryless Uniform, Gaussian, Laplacian and Gamma sources, whose performance often exceeds that so far reported in the literature, including that for TCQ codes. At a source coding rate of one bit per sample the performance at 512 states is 0.24 dB from the Shannon limit f

Objective: This study aimed to observe how levels of total cortisol, calculated free cortisol, corticosteroid-binding globulin, and adrenocorticotropic hormone change during the early course of human acute pancreatitis and to describe how these changes affect the development of pancreatic necrosis. Design and Patients: In a total of 109 consecutive patients with acute pancreatitis (74 with edemato

Popular Abstract in Swedish Bakgrund Denna studie är en undersökning av barns musikskapande med synthesizer och dator. I studien deltog nio barn i åttaårsåldern. Musik utgör en viktig del i barns och ungdomars vardag och den stora exponering för musik som sker i vårt samhälle innebär att ingen är någon musikalisk nybörjare. Det är väl känt att barn kan skapa musik på egen hand, mest är det dock bToday’s children live in a world where music in all its different forms has become a significant factor in their everyday life. From earlier research we know that young children are able to create music by singing and using musical instruments. The present study was undertaken with eight-year-old children in school year 2 in order to investigate the children’s composing and composition processes u

Three isoforms of the major birch pollen allergen, Bet v, 1 from Betula verrucosa have been expressed as recombinant proteins in E. coli and purified. The immunochemical properties of recombinant isoforms (rBet v 1) differed on immunoblots when compared using Mabs and birch pollen allergic patients serum IgE. 2-D gel analysis showed that recombinant isoforms with different epitope structure can fo

There is a need for tools that in a simple way can be used for the evaluation of image quality related to clinical requirements in mammography. The aim of this work was to adjust the present European image quality criteria to be relevant also for digital mammography images, and to use as simple and as few criteria as possible. A pilot evaluation of the new set of criteria was made with mammograms

The uptake and killing of bacteria by human neutrophils are dependent on the fusion of secretory granules with forming phagosomes. The earliest component of exocytosis was found to precede phagosome closure, so that granular membrane constituents were detectable on the plasmalemma. We show that during phagocytosis of IgG-opsonized particles, this early secretory response is highly polarized in the

We have studied the dynamics of water molecules in six crystal structures of four human cytochromes P450, 2A6, 2C8, 2C9, and 3A4, with molecular dynamics simulations. In the crystal structures, only a few water molecules are seen and the reported sizes of the active-site cavity vary a lot. In the simulations, the cavities are completely filled with water molecules, although with similar to 20% low

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 within the fluid.

PURPOSE: To characterize the clinical phenotype, with emphasis on electrophysiology, of members of a Swedish family with autosomal dominant retinitis pigmentosa due to a novel mutation, F211L, in the peripherin/RDS gene. METHODS: Nine patients with autosomal dominant retinitis pigmentosa and two healthy family members underwent a full clinical evaluation including kinetic visual field testing, mea

Zeaxanthin, an important component in protection against overexcitation in higher plants, is formed from violaxanthin by the enzyme violaxanthin de-epoxidase. We have investigated factors that may control the maximal degree of conversion in the violaxanthin cycle. The conversion of violaxanthin to zeaxanthin in isolated spinach thylakoids was followed at different temperatures and in the presence
