The major part of the Swedish hydro power development took place between 1945 and 1975. At that point of time, significant progress had been made regarding the use of high quality concrete for hydraulic structures. In spite of the progress made, deterioration of concrete due to freezing and thawing is still frequent. Superficial damage at the waterline and spalling of concrete far below the water

Anomalous background due to charging in the proton-induced X-ray analysis of insulators is eliminated by inserting a heated carbon filament or by raising the pressure in the sample chamber.

This thesis consists of three papers in which different topics in spaces of analytic functions are considered. These papers are: I. "Estimates in Möbius Invariant Spaces of Analytic Functions." II. "Preduals of Q_p-spaces and Carleson Embeddings of Weighted Dirichlet Spaces." III. "On the Spectrum of the Cesàro Operator on Spaces of Analytic Functions." The first two papers are closely related

This paper presents an evaluation of single input single output (SISO), single input multiple output (SIMO) and multiple input multiple output (MIMO) channel capacities for a dual antenna prototype in proximity of a user. The dual antenna prototype mimics today’s small mobile phone design in size and in comprising internal, compact, multi-band antennas. Four different user cases are evaluated by m

We have calculated the electronic structure of InAs quantum dots embedded in InP as a function of size, using strain dependent eight-band k.p theory in the envelope function approximation. A realistic three-dimensional shape was used for the simulations and the piezoelectric polarization of the system was included. In order to avoid spurious solutions, an extra term was added to the Hamiltonian. P

This article presents a rational institutionalist account of why the Commission and the ECJ vary in their capacity to pursue successfully a supranational agenda. In the empirical part, the explanatory power of this approach is illustrated through a comparison of the Commission's and the ECJ's autonomy in the pursuit of a joint agenda in EU enforcement. The article suggests that the EU as a strateg

Objective. To study the clinical recovery from acute otitis media ( AOM) in children, 2-16 years of age, managed with or without treatment with phenoxymethylpenicillin ( PcV). Design. An open, prospective randomized trial. Children aged between 2 and 16 years, presenting with one- or double-sided AOM ( without perforation) with symptom duration of less than four days, were included. The children w

Using gene array technology, we recently observed for the first time an up-regulation of laminin alpha4 chain in human gliomas. The data were validated by semiquantitative reverse transcription-PCR for RNA expression and immunohistochemistry for protein expression. Moreover, increase of the alpha4 chain-containing laminin-8 correlated with poor prognosis for patients with brain gliomas. Therefore,

A blend of rapeseed and butter oil was transesterified using immobilized Thermomyces lanuginosus lipase (Lipozyme (R) TL IM) as catalyst. The reaction was followed by reversed-phase HPLC and the triacylglycerol peaks were tentatively identified from their elution times by calculating equivalent carbon numbers. Further identification was made using HPLC-electrospray tandem mass spectrometry. A few

The present study investigated the brain mechanisms involved during young children's receptive familiarization with new words, and whether the dynamics of these mechanisms are related to the child's productive vocabulary size. To this end, we recorded event-related potentials (ERPs) from 20-month-old children in a pseudoword repetition task. Results revealed distinct patterns of repetition effects

The economic feasibility of preconcentrating dilute sugar solutions prior to fermentation is investigated. Two methods, evaporation and reverse osmosis, are compared. A computer program to determine the optimal preconcentration conditions for glucose solutions of 1.5–16 wt% has been developed. It was used to compute the fractional cost for labor and maintenance, preconcentration, fermentation, and

Background: Chronic Pseudomonas aeruginosa (PA) infection causes increased morbidity and mortality in cystic fibrosis (CF). This study aimed to answer the following questions: Does the prevalence of chronic infection with PA differ between the CF centres in Scandinavia? Which differences exist concerning segregation and treatment of PA? Methods: 989 patients (86%) from all eight CF-centres in Scan

Monocot residues such as corn stover and straw are often not fully exploited and constitute a potential substrate for bioethanol production. However, a number of factors such as high enzyme loadings make large-scale utilization economically difficult. Addition of non-ionic surfactants and poly(ethylene glycol) to enzymatic hydrolysis of various lignocellulosic substrates has been found to increase
