Evidensbaserad omvårdnad, sjukvård och kunskap

Research within nursing and medicine is moving at an increasing pace. This makes it difficult for the staff - involved with medical care to find the right path through all the new research and development. Working according to evidencebased procedures within both medicine and nursing means using in one’s work the recommendations which have been based on literature studies that have compiled, revie

A comparison of splittings and integral equation solvers for a nonseparable elliptic equation

Iterative numerical schemes for solving the electrostatic partial differential equation with variable conductivity, using fast and high-order accurate direct methods for preconditioning, are compared. Two integral method schemes of this type, based on previously suggested splittings of the equation, are proposed, analyzed, and implemented. The schemes are tested for large problems on a square. Par

Modelling of Traffic Loads on Bridges Based on Measurements of Real Traffic Loads in Sweden

Popular Abstract in Swedish Denna rapport behandlar trafiklaster på broar och de lasteffekter som de ger upphov till. Böjmoment och tvärkraft för olika brotyper beskrivs i form av statistiska fördelningar med tillhörande parametrar. Dessa är baserade på mätningar av verklig trafik gjorda i Sverige under åren 2002-2003 i Vägverkets regi. Resultaten finns redovisade i Vägverket (2004b), och finns laThis thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. The statistical distributions are based on measurements of real traffic, made in Sweden during 2002-2003. The measurements are managed by the Swedish R

Lacunar infarcts, small deep infarcts resulting from occlusion of a penetrating artery, account for about a quarter of all ischemic strokes. The view of lacunar infarcts as a benign and rather innocent vascular lesion has been modified during the last years. Although the prognosis is more favourable than other subtypes during the first years, probably due to the small lesion size, in a longer pers

Photoluminescence quenching at a polythiophene/C-60 heterojunction

Quenching of photoluminescence in a substituted polythiophene in the presence of a deposited C-60 layer is studied by steady-state and time-resolved photoluminescence (PL). The steady-state PL is evaluated by con -sidering the interference of the absorbed and emitted electro-optical field in the thin film coupled to exciton diffusion in the conjugated polymer. PL quenching occurs for excitons gene

Diffusivity measurements using holographic laser interferometry in a cubic lipid-water phase

The diffusion of glucose in a cubic lipid-water phase was studied with holographic laser interferometry. The X-ray diffraction data showed that the structure of the cubic phase could be described as a primitive cubic lattice under the experimental conditions used. The present study shows that holographic laser interferometry is suitable for determining the concentration profile due to diffusion, e

The natural history of adnexal cysts incidentally detected at transvaginal ultrasound examination in postmenopausal women

OBJECTIVE: To determine the natural history of adnexal cysts incidentally detected at transvaginal ultrasound examination and judged to be benign in postmenopausal women.METHODS: One hundred and thirty-four postmenopausal women referred for ultrasound examination and found to have an adnexal cyst judged to be benign and not causing any symptoms were followed with transvaginal ultrasound at 3, 6 an

Photoelectrocatalytic oxidation of NADH with electropolymerized Toluidine Blue O

A poly(Toluidine Blue O) (poly-TBO) modified electrode was successfully prepared by repeated sweeping the applied potential from -0.6 to + 0.8 V (vs. SCE) on a glassy carbon electrode (GCE) in borate buffer solution at pH 9.1 containing 0.1 M NaNO3 and 0.4 mM Toluidine Blue 0 (TBO). The poly-TBO modified GCE shows electrocatalytic activity toward NADH oxidation in phosphate buffer solution at pH 7

Empowering Teachers in Times of Change. The Swedish Comprehensive School System

Relative autonomy refers to the space that teachers have or can create to make choices regarding the curriculum of schooling. In order to transform conflicts and to cope with the tensions that arise in time of change, teachers are urged to make constructive use of their relative autonomy. In this paper some of the conflicts and tensions that exist today are discussed in the context of the Swedish

Effects on the function of arctic ecosystems in the short- and long-term perspectives

Abstract in UndeterminedHistorically, the function of Arctic ecosystems in terms of cycles of nutrients and carbon has led to low levels of primary production and exchanges of energy, water and greenhouse gases have led to low local and regional cooling. Sequestration of carbon from atmospheric CO2, in extensive, cold organic soils and the high albedo from low, snow-covered vegetation have had imp

Synaptic dysfunction in Huntington's disease: a new perspective

Huntington's disease (HD) is caused by a polyglutamine expansion in the protein huntingtin and is characterized by intraneuronal inclusions and widespread neuronal death at the late stage of the disease. In research, most of the emphasis has been on understanding the cell death and its mechanisms. Until recently, it was believed that the vast majority, if not all, of the symptoms in HD are a direc
