A compilation of the applied experimental conditions when studying metal ion adsorption onto kraft fibres, and the resulting conclusion, revealed that the ionic strength conditions used during the experiments were an important dividing factor. At low ionic strengths, the conclusion has regularly been that the Donnan ion-exchange model could correctly predict the adsorption while, at higher ionic s

Both the electronic structure and the `breathing-mode' relaxation for tetrahedral interstitial 3D transition atom impurities in silicon are studied in the local-density approximation. The calculations show that although the interstitial 3d impurities constitute a very large perturbation locally, they interact rather weakly with the surrounding crystal in the sense that they perturb the spatial dis

A sum rule valid for a large class of linear and reciprocal antennas is presented in terms of the electric and magnetic polarizability dyadics. The identity is based on the holomorphic properties of the forward scattering dyadic and includes arbitrarily shaped antennas modelled by linear and time-translational invariant constitutive relations. In particular, a priori estimates on the partial reali

Huvuddragen i det konstitutionella fördragsutkastet har bevarats i Lissabon-överenskommelsen, men de högtflygande formuleringarna har tonats ned och ambitionen att skapa en bred förankring för den europeiska tanken har övergivits. Känslomässiga bindningar ska elimineras och ersättas av tekniskt formulerade ändringar i existerande fördrag. Återigen ett tilläggsavtal till det ursprungliga Romfördra

Hemodynamic effects of iso-oncotic 3% dextran-60, 6% dextran-70, and Ringer's acetate were compared in 28 male pigs (25 to 30 kg) subjected to experimental trauma and hemorrhage. The animals were kept anesthetized with 75% N2O/25% O2, 0.8% halothane. Hemodynamic and respiratory conditions were allowed to stabilize for one hour preoperatively (baseline data). After surgical trauma (arthroplasty), t

p16(INK4a), p15(INK4b), p18(INK4c) and p19(INK4d) comprise a family of cyclin-dependent kinase inhibitors and tumor suppressors. We report that the INK4 proteins share the ability to arrest cells in G1, and interact with CDK4 or CDK6 with similar avidity. In contrast, only p18 and particularly p19 are phosphorylated in vivo, and each of the human INK4 proteins shows unique expression patterns depe
