Popular Abstract in Swedish I de flesta fall börjar knäledsförslitning i den inre ledkammaren (medial gonartros) och medför en successiv hjulbenthet (varus). I enstaka fall börjar förslitningen i den yttre ledkammaren (lateral gonartros) innebärande kobenthet (valgus). Personer över 60-65 år behandlas kirurgiskt oftast med knäledsprotes med bra resultat. Hos yngre, mer aktiva, är denna metod sämreOsteotomy is used for correction of the altered load on the gonarthrotic knee joint. It can be performed above or below the knee. Clinical results depend on the correction after bone healing. By tibial closed wedge osteotomy (HTO), the deformity is corrected peroperatively in contrast to tibial hemicallotasis osteotomy (HCO) where the correction is performed after surgery. Comparing the two method

The presence of a specialised dorsal rim area with an ability to detect the e-vector orientation of polarised light is shown for the first time in a nocturnal hymenopteran. The dorsal rim area of the halictid bee Megalopta genalis features a number of characteristic anatomical specialisations including an increased rhabdom diameter and a lack of primary screening pigments. Optically, these special

Several strains belonging to genera Pseudomonas and Achromobacter and characterized by the ability to degrade anionic surfactants were tested as potential bases of microbial biosensors for surfactant detection. For each strain the substrate specificity and stability of sensor signals were studied. The total amount of the substrates tested (including carbohydrates, alcohols, aromatics, organic acid

Analytic expressions for the exact bit error probabilities of rate R = 1/2, memory m = 2 convolutional encoders are derived for a maximum-likelihood (ML) decoder and transmission over the binary-symmetric channel (BSC). The resulting expressions are rational functions of the crossover probability of the BSC. In addition to classical nonsystematic encoders without feedback, we consider also recursi

In a Northern country such as Sweden, energy use in the home may be reduced by 20% through changes in behaviour. However, little is known about how households respond to policy instruments encouraging such change or to what degree this in turn may affect the workload of women and men in such communities. The current study presents findings from interviews with 30 households in Sweden that particip

n instrument suitable for measuring the total water content both as small liquid droplets and as vapour in the air, in water mist total flooding extinguishing tests, is presented. The instrument consists of a heater and a Vaisala humidity meter. The Vaisala humidity meter is capable of measuring relative humidity at temperatures up to 180°C. The instrument has a measuring range of 0-600g/m3, a sam

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

The potential risk for consumers to be exposed to banned azo dyes in leather is strong motivation for the development of an analytical test procedure with improved accuracy. The currently most accepted analytical procedure for this application, the German standard DIN 53316 method, suffers from major drawbacks including low accuracy and the usage of hazardous organic solvents. As a consequence, an

Current internal radiation dosimetry models for the small intestine, and for most walled organs, lack the ability to account for the activity uptake in the intestinal wall. In existing models the cross-dose from nearby loops of the small intestine is not taken into consideration. The aim of this investigation was to develop a general model for calculating the absorbed dose to the radiation-sensiti

Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,

This review summarizes and discusses the use of central health registers in studies of causes of congenital malformations. The review is illustrated using data from the Swedish Medical Birth Register with adjacent registers and gives examples of different methods to identify environmental exposures. The review stresses the usefulness of this approach but also the inherent problems of which the res

The metallation of tetrapyrroles is believed to proceed via a sitting-atop (SAT) complex, in which some of the pyrrole nitrogen atoms are protonated and the metal ion resides above the ring plane. No crystal structure of such a complex has been presented, but NMR and EXAFS (extended X-ray absorption fine structure) data has been reported for Cu2+ in acetonitrile, which have been interpreted as the
