Controlling structure in associating polymer-surfactant mixtures

Structures of concentrated mixtures of associating polymer-surfactant mixtures are important in many technical applications. Yet an in-depth understanding of how molecular parameters affect these structures is lacking. We here summarize the results of ongoing work using a novel simplified approach to the study of associating oppositely charged polymer-surfactant mixtures, introducing a minimum num

Nonyrast States in the Odd-odd N = Z Nucleus 62Ga

Low-lying excited states in the odd-odd N = Z nucleus 62Ga have been investigated following the heavy-ion fusion-evaporation reaction 40Ca(24Mg,pn)62Ga near the Coulomb barrier. Special emphasis is devoted to the search for nonyrast states. The extended decay scheme of 62Ga is compared to spherical shell-model calculations employing the pf5/2g9/2 valence space.

Posterolateral lumbar fusion. Outcome of 71 consecutive operations after 4 (2-7) years

We report the outcome of 71 consecutive posterolateral lumbar fusions without spinal instrumentation. The indication for the operation was spondylolysis-olisthesis, degenerative disc disease/facet joint arthrosis, or pain after prior laminectomy. Concerning pain relief, 29/43 patients with spondylolysis-olisthesis were classified as good. The corresponding figures in the group with degenerative di

Active heat capacity : models and parameters for the thermal performance of buildings

The thesis concerns the characterization and evaluation of nonsteady heat transfer in building components and building enclosures. The major aim of the underlaying research has been to assemble and develop simplified calculation procedures for this purpose. To establish a simple model for heat balance calculations three main items are treated: simplification of the heat transfer operators, the des

Burn injuries in small children, a population-based study in Sweden.

Aims and objectives. The aim of this study was to describe characteristics in burn injuries in children (zero to six years old), consulting primary care and hospital-based care in Malmo, Sweden. Burn-injured children consulting the University Hospital or the 21 Health Centres, during year 1998 and year 2002, were included. Background. Epidemiological studies of burns in children have mostly been h

Popular Abstract in DanishLivsbaner gennem et felt viser hvorledes eliteidrætsudøvere klarer sig i samfundet efter livet i sporten. Spørgsmålet er om erhvervelse af fysisk sportskapital i sportsfeltet, medieret gennem berømmelse, medvirker til at opnå et arbejde eller en bestemt placering i samfundet. Sportskapital bidrager måske til social mobilitet. Dette er belyst gennem konkrete undersøgelser The thesis deals with a theoretical outline of the theory of reconversions in the light of the social space, with an analysis of top level athletes' mobility and strategies of reconversions in their trajectories through the relative autonomous field of sports. Some disciplines in this field have much autonomy, others less, and are positioned according to a state of distribution of the specific cap

Activation of contraction and ATPase activity in intact and chemically skinned smooth muscle of rat portal vein. Dependence on Ca++ and muscle length

The mechanical manifestations of muscle contraction (force development or shortening) are accompanied by an increased turnover of chemical energy (ATPase activity, JATP). In intact rat portal veins activated by high potassium medium to produce graded contractions at different levels of extracellular calcium, a linear dependence of oxygen consumption on force was found. The slope of the relation (m

Transendothelial transport: the vesicle controversy.

The relative contribution of transcytosis vs. large pore transport to the passage of macromolecules across microvascular endothelia has been a controversial issue for nearly half a century. To separate transcytosis from 'porous' transport, the transcytosis inhibitors N-ethylmaleimide (NEM) and filipin have been tested in in situ or ex vivo perfused organs with highly conflicting results. In contin

Initial Fires. RHR, Smoke Production and CO Generation from Single Items and Room Fire Tests

This report is to be used as a guide in determining what an initial fire will look like. It is a summary of a large number of full scale tests on different items and under various conditions performed at different laboratories. The results shown are primarily the rate of heat release (RHR), as well as the production of smoke and generation of carbon monoxide. The results are shown as curves in thi

Isolated hypervariable regions derived from streptococcal M proteins specifically bind human C4b-binding protein: Implications for antigenic variation

Antigenic variation in microbial surface proteins represents an apparent paradox, because the variable region must retain an important function, while exhibiting extensive immunological variability. We studied this problem for a group of streptococcal M proteins in which the similar to 50-residue hypervariable regions (HVRs) show essentially no residue identity but nevertheless bind the same ligan

Energianvändning och energibesparing i Malmö : undersökning av ett höghus

I rapporten redovisas mätningar av energianvändningen i flerbostadshus. Mätningar gjordes under fyra eldningssäsonger. Med åtgärder som fönstertätning, inreglering av radiator- och ventilationssystem m m erhölls energibesparingar om 9-21% i förhållande till första säsongens mätning utan åtgärder.

Inclusive D*(+/-) meson and associated dijet production in deep-inelastic scattering at HERA

Inclusive D*(+/-) production is measured in deep-inelastic ep scattering at HERA with the H1 detector. In addition, the production of dijets in events with a D*(+/-) meson is investigated. The analysis covers values of photon virtuality 2 <= Q(2) <= 100 GeV2 and of inelasticity 0.05 <= y <= 0.7. Differential cross sections are measured as a function of Q(2) and x and of various D*(+/-) meson and j

Intervention thresholds for osteoporosis

The aim of this study was to determine the threshold of fracture probability at which interventions become cost-effective. We modeled the effects of a treatment costing $500/year, given for 5 years, that decreased the risk of all osteoporotic fractures by 35%, followed by a waning of effect for 5 years. Sensitivity analyses included a range of effectiveness (10%-50%) and a range of intervention co

Quality of life after stroke: well-being, life satisfaction, and subjective aspects of work.

Stroke incidence in those of working age has been reported to be increasing significantly, implying strong incentives for research concerning working ability after stroke. This study focused on differences in subjective aspects of work and dimensions of quality of life after having experienced stroke. Sixty-five persons answered a postal questionnaire. The median age at the time of the stroke was
