Nationwide population-based study on 30-day mortality after radical prostatectomy in Sweden

Objective. The incidence of prostate cancer in Sweden is increasing rapidly, as is treatment with curative intent. Radical prostatectomy (RP) is currently commonly performed, either within or outside large high-volume centres. The aim of this study was to assess the 30-day mortality rate after RP in Sweden. Material and methods. In this nationwide population-based study, all men diagnosed with loc

Early Vision Optimization: Parametric Models, Parallelization and Curvature

Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. Many of these tasks are formulated as optimization problems and one of the key factors for the success of recent methods is that they seek to compute globally optimal solutions. This thesis is c

eta Carinae: linelist for the emission spectrum of the Weigelt blobs in the 1700 to 10 400 angstrom wavelength region

Aims. We present line identifications in the 1700 to 10 400 angstrom region for the Weigelt blobs B and D, located 0.'' 1 to 0 ''.3 NNW of Eta Carinae. The aim of this work is to characterize the behavior of these luminous, dense gas blobs in response to the broad highstate and the short low-state of. Carinae during its 5.54-year spectroscopic period. Methods. The spectra were recorded in a low st

Report from the NUH-project: Udvikling af instrument til undersogelse af nytte og effekt af mobilitetshjaelpemidler - The Nordic Assisted Mobility Evaluation (NAME)

This report covers the project period from 1.4.2003 to 31.08.2005. Project organisation, administration including the accounts, and the work carried out are reported. Besides, suggestions for copyright are put forward together with plans for dissemination activities and need for further research. The NAME was developed by the project group, consisting of all partners who have all contributed in an

Statistical Mechanical Studies of Titrating Polyelectrolytes

Popular Abstract in Swedish Som titeln antyder behandlar avhandlingen titrerande polyelektrolyter, d.v.s. stora molekyler med många syra-basgrupper. Sådana molekyler kan vi finna lite överallt, ja till och med i våra kroppar, som innehåller en mängd olika polyelektrolyter. Deras egenskaper kan variera starkt beroende på omständigheterna och har många biologiska och industriella tillämpningar. Att Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. Sampling is facilitated for the latter two by the use of pivot

Cars in Transition - An Assessment of Future Vehicle Technologies

The transport sector is facing serious challenges in meeting long-term sustainability criteria. Radical changes in the design of vehicles to attain competitive vehicles with substantially better environmental performance will probably constitute an important part in a future sustainable transport sector. The aim of the study described in this thesis is to assess the long-term options currently und

Peak and Power Reduction in Multicarrier Communication Systems

Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. This thesis puts focus on PAR reduction for wireline communication systems, in particular for the mul

Packaging for eco-efficient supply chains - exploring factors in the packaging development process

Purpose: Supply chain efficiency (economic and ecological) is affected by packaging design. The purpose of this research is to investigate how integrated approaches aiming for ecoefficient supply chains are used in packaging development processes and how a set of preselected factors influences the adaption of more or less integrated approaches at companies. Design/methodology/approach: The researc

Reevaluation of the species of Hieracium sect. Hieracium that were described by Hylander from introduced populations in Scandinavian parks

Hylander treated 144 species of Hieracium sect. Hieracium found in Scandinavian parks, 132 of which were described for the first time. However, he did not supply any determination key, only a few species were illustrated and hints about the differences between species were few. In addition, the species concept of Hylander was obviously much narrower than what has been agreed upon by those working

Sexual child abuse in a defined Swedish area 1993-97: a population-based survey

Attempting to avoid some of the most common methodological problems involved in research on sexual child abuse, we collected data on crimes, perpetrators, and sanctions in all convicted cases of sexual child abuse in a defined population during a 5-year period. This approach provided amply documented and ascertained cases with precise definitions and descriptions of the crimes involved, no clinica

The role of K2O in the selective reduction of NO with NH3 over a V2O5(WO3)/TiO2 commercial selective catalytic reduction catalyst

To elucidate the nature of the acid sites of the V2O5(WO3)/TiO2 catalyst upon K2O addition and its relation to the selective reduction of NO with NH3, measurements were made by means of infrared and Raman spectroscopy, NH3 chemisorption, and NO reduction measurements as a function of the K2O loading. The catalytic activity was found to decrease rapidly with the K2O loading, irrespective of the sim

Hearing loss after "refractory'' secretory otitis media

Conclusions. The results indicate that SOM of extreme duration, and maybe also the treatment of SOM, are risk factors for developing permanent hearing loss, both conductive and sensorineural. Objective. Fluctuating or persisting hearing loss of varying degrees is known to accompany secretory otitis media ( SOM). The aim of this study was to detect possible hearing sequelae in young adults who had

Våld mot invandrarkvinnor. Kvinnors berättelser och socialtjänstens strategier.

In recent years domestic violence has become an issue of major importance in Sweden. This is a fact to be observed in mass media but also in changes made in legislation. As concern and attention raises, new victim groups are "discovered". Among these we find women who have come to Sweden as refugees, through their marriage to Swedish men, or when reunited with a husband who arrived earlier. These

Effect of free-stream turbulence on heat transfer and fluid flow in a transonic turbine stage

In the present work, a numerical study has been performed to simulate the effect of free-stream turbulence, length scale and variations in rotational speed of the rotor on heat transfer and fluid flow for a transonic high-pressure turbine stage with tip clearance. The stator and rotor rows interact via a mixing plane, which allows the stage to be computed in a steady manner. The focus is on turbin

Models for Estimation of Software Faults and Failures in Inspection and Test

Popular Abstract in Swedish Programvara spelar en allt viktigare roll i industriella produkter. Bilar, flygplan, telefoner, hemelektronik, kärnkraftverk m.m. innehåller alla programvara. När man utvecklar programvara blir det ofta fel i produkterna, fel som kan vara mycket allvarliga för funktion och säkerhet. Ett första steg i att minska dessa fel är att uppskatta hur många fel som finns i produk

Search for an LSP gluino at LEP with the DELPHI detector

In some supersymmetric models, the gluino ((g) over tilde) is predicted to be light and stable. In that case, it would hadronize to form R-hadrons. In these models, the missing energy signature of the lightest supersymmetric particle is no longer valid, even if R-parity is conserved. Therefore, such a gluino is not constrained by hadron collider results, which looked for the decay (g) over tilde -
