A method, based on the multiconfiguration Hartree-Fock approach, for ab initio calculations of Rydberg states has been developed. The method has been tested for a number of highly excited Rydberg states, with quantum numbers l = 4 - 8 and n <= 9, in Mg-like and Be-like ions. The results are compared with Hartree-Fock calculations to investigate the influence of correlation and, to a lesser extent,
Partial reduction of vanadia supported on silica-titania by NH3 + NO has been studied by electrical conductance and ESR measurements. The relationship between electrical conductance and degree of reduction was determined by oxidative and reductive titrations of V(IV) and V(V) species leached from catalyst samples which had been reduced to different levels. In situ monitoring of the steady-state V(
The aim of this report is to present some of the variable uncertainties associated with the dimensioning of fire protection in buildings and risk analysis in buildings (with respect to fire). A method for assessing the fire frequency in a building is presented along with examples of how the assessed fire frequency can be improved using fire data from a specific building. The probability of differe

A kinematic hardening plasticity model valid for finite strains is presented. The model is based on the well-known multiplicative split of the deformation gradient into elastic and plastic parts. The basic ingredient in the formulation is the introduction of a locally defined configuration-a centre configuration-which is associated with a deformation gradient that is used to characterize the kinem
To determine the impact of a family history of the common form of type 2 diabetes and the phenotype of the proband on anthropometric and metabolic variables in normoglycemic first degree relatives, we studied 2100 first degree relatives of patients with the common form of type 2 diabetes (FH+) and 388 subjects without a family history of diabetes (FH-). All subjects participated in an oral glucose
Indications of what the tour-operating sector considers to be 'good practice' can be drawn from voluntary initiatives such as existing eco-labels and codes of conduct. However, practical implementation of such guidance varies greatly from one tour operator to another, depending on different types of factors, such as size, financial capacity, corporate structure, operational location, organizationa
Popular Abstract in Swedish Tekniken för vitreoretinal kirurgi har utvecklats betydligt de senaste åren, både vad gäller metodik och instrumentering. Allt fler sjukdomstillstånd i näthinnan kan nu behandlas. För att utveckla dessa metoder vidare, och även öka kunskapen bakom verkningsmekanismen för deras effektivitet, är standardiserade djurmodeller där både funktion och histologi kan utvärderas aThe field of vitreoretinal surgery has expanded greatly over the last decades. A continuous refinement of surgical methods and instruments has increased the number of treatable retinal disorders. Vitrectomy, retinectomy and laser treatment are all part of the modern surgical arsenal. In order to further develop and refine these methods, and also to improve the knowledge of the mechanisms behind th
An unexpected discovery of Caloplaca lobulata in Tasmania is presented. This species which earlier seemed rather widely spread in central Europe have today become an extremely rare and endangered element in the European lichen flora. The generic affinity with other closely related species is briefly discussed.
A statistical approach to a posteriori blockmodeling for digraphs and valued digraphs is proposed. The probability model assumes that the vertices of the digraph are partitioned into several unobserved (latent) classes and that the probability distribution of the relation between two vertices depends only on the classes to which they belong. A Bayesian estimator based on Gibbs sampling is proposed
Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. Paper I examines the properties of a maximum likelihood method for aligning vectorcardiographic loops, with
