Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. Therefore, better algorithms must be developed in order to adva
Syftet med rapporten har varit att analysera erfarenheterna av miljöanpassad upphandling och innovationsupphandling, samt hur dessa styrmdel kan bidra till uppfyllandet av olika politiska målsättningar. Rapporten redogör bl.a. för målsättningarna för upphandling, betydelsen av en efterfrågedriven innovationspolitik, samt hur upphandling kan samverka med andra styrmedel på miljöområdet.
Objective To estimate the diagnostic accuracy and interobserver agreement in predicting intracavitary uterine pathology at offline analysis of three-dimensional (3D) ultrasound volumes of the uterus. Methods 3D volumes (unenhanced ultrasound and gel infusion sonography with and without power Doppler, i.e. four volumes per patient) of 75 women presenting with abnormal uterine bleeding at a bleeding
Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants becaus
The ATLAS Collaboration measures the inclusive production of Z bosons via their decays into electron and muon pairs in p + Pb collisions at root S-NN = 5.02 TeV at the Large Hadron Collider. The measurements are made using data corresponding to integrated luminosities of 29.4 and 28.1 nb(-1) for Z -> ee and Z -> mu mu, respectively. The results from the two channels are consistent and combined to
Potential applications of grating-based X-ray phase-contrast imaging are investigated in various fields due to its compatibility with laboratory X-ray sources. So far the method was mainly restricted to X-ray energies below 40 keV, which is too low to examine dense or thick objects, but a routine operation at higher energies is on the brink of realisation. In this study, imaging results obtained a
This article outlines a potential synergy between sustainability and well-being research. Currently aims within well-being and sustainability research focus on increasing well-being. First, sustainability is defined and important concepts within it highlighted, that is, aims, interdependencies, constraints, values and balanced adaptive processes. It is suggested that positioning well-being more cl
Since its publication in 1962, Mats P. Malmer’s book Jungneolithische Studien has heavily influenced subsequent work on the Swedish-Norwegian Battle Axe Culture. Malmer characterized burial customs as strictly regulated and conservative. Recent archaeological activity in the province of Scania, southern Sweden, provides us with an augmented empirical basis for testing Malmer’s conclusions. In addi
Background: Previous studies in the rat have shown that the spatial organisation of the receptive fields of nociceptive withdrawal reflex (NWR) system are functionally adapted through experience dependent mechanisms, termed somatosensory imprinting, during postnatal development. Here we wanted to clarify 1) if mice exhibit a similar spatial encoding of sensory input to NWR as previously found in t
Characterization of the glomerular filtration barrier is of fundamental importance for understanding the pathophysiology of proteinuric kidney diseases. Furthermore, it can be of key value in the understanding of microalbuminuria, which is often associated with endothelial dysfunction in conjunction with cardiovascular disease. In the four studies of this doctoral thesis, macromolecular probes hav
Background: Treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has improved, but there is a considerable fraction of patients experiencing a poor outcome. There is a need for better prognostic markers and aberrant DNA methylation is a candidate in other malignancies, but its potential prognostic significance in T-ALL is hitherto undecided. Design and Methods: Genome wide promoter D
The main theme of this review is the many-body physics of vortices in quantum droplets of bosons or fermions in the limit of small particle numbers. Systems of interest include cold atoms in traps as well as electrons confined in quantum dots. When set to rotate, these in principle different quantum systems show remarkable analogies. The topics reviewed include the structure of the finite rotating
The yrast sequence of the neutron-rich dysprosium isotope Dy-168 has been studied using multinucleon transfer reactions following collisions between a 460-MeV Se-82 beam and an Er-170 target. The reaction products were identified using the PRISMA magnetic spectrometer and the gamma rays detected using the CLARA HPGe-detector array. The 2(+) and 4(+) members of the previously measured ground-state
Our understanding of metal-atom cluster adsorption on graphene on Ir(111) is based on elementary chemical ideas, rehybridization, and buckling, supported by density functional theory (DFT) calculations. We tested the DFT picture by comparing calculated core level spectra to x-ray photoemission spectroscopy (XPS) measurements. For pristine graphene, which forms a gently undulating moire on Ir(111),
Experiments performed in a lab are often considered generali- zable over both people and social settings. The problems with generalizing over different groups of people are well known, but it is only recently that changes in behavior depending on thesocial setting have been examined. Large changes in behavior can be seen in trivial cognitive tasks, depending on whether the participant is alone or
Popular Abstract in Swedish SAMMANFATTNING (SUMMARY IN SWEDISH) Jod är nödvändigt för utvecklingen och hälsan hos alla högre djur inklusive männi-ska, men det är ett relativt sällsynt grundämne. Man får i sig jod via kosten och det högsta jodinnehållet har fisk och skaldjur eftersom havssalt innehåller jod. Jod finns även i mejeriprodukter och i mindre mängder i grönsaker, men jodinnehållet i dessABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. Active iodide transport into thyroid fol-licular cells is mediated by the sodium/iodide symporter (NIS), powered by Na+/K+-ATPase. NIS is expressed also in extra
