In 1998 renewable energy sources supplied 56 ± 10 exajoules,or about 14 percent of world primary energy consumption. Thesupply was dominated by traditional biomass (38 ± 10 exajoules a year. Other major contributions came from large hydropower (9 exajoules a year) and from modern biomass (7 exajoules). The contribution of all other renewables — small hydropower, geothermal, wind, solar, and marine

Resistance of Concrete to Chloride Ingress sets out current understanding of chloride transport mechanisms, test methods and prediction models. It describes basic mechanisms and theories, and classifies the commonly used parameters and their units which expressing chloride and its transport properties in concrete. Laboratory test methods and in-field applicable test methods, including precision re

Designing multimodal interfaces is a complex process. One of the steps is to decide what kind of information should be presented for the adressee and in what medium the message should be conveyed. The starting point in this paper is information mapping and modality theory. The paper discusses the strenghts and the weaknesses of language and pictorial representations as presented in Bernsen (1994).

The HOO radical is a key intermediate in the atmosphere and is involved in a large number of reactions, including ozone loss cycles in the stratosphere and oxidation processes in the troposphere. This theses is a study of the HOO radical and its interactions with a number of small molecules that are present in the atmosphere. The HOO complexes were formed on the surface of growing argon matrices

Popular Abstract in Swedish Åldrandet innebär fysiologiska förändringar i många olika organ t.ex hjärta, kärl och nervsystem. Även ämnesomsättning och behov av olika näringsämnen förändras, vilket innebär en ökad risk att drabbas av olika sjukdomstillstånd. Detta påverkar även den åldrande hjärnan som kan drabbas av mer eller mindre omfattande förändringar, i såväl blodkärl som nervceller. Mindre The aim of this study was to evaluate the diagnostic potentials of four different biochemical markers, serum cobalamin, blood folate, plasma homocysteine and serum methylmalonic acid for diagnosis of cobalamin/folate deficiency in a psychogeriatric population. The second aim was to investigate the relationship between these markers and various clinical and functional parameters of the nervous syst

The aim of the user related assessment is to evaluate the effects on driver behaviour, reactions to and acceptance of the driver assistance system: Continuous Support (CS) function developed by CRF within the framework of SECONDS subproject. The CS function continuously evaluates the status of the host vehicle as well as the surrounding traffic based on the information of the on-board sensors. Whe

1815 införde Sverige jury i tryckfrihetsmål. I denna bok undersöks bl a syftet bakom reformen och vilka följderna blev av den. Uppfattas juryn idag främst som ett skydd eller ett hot? I exempel på tryckfrihetsmål möter läsaren politiker och publicister som exempelvis Carl XIV Johan mot Lars Johan Hierta, Oscar II mot Hjalmar Branting och Axel Danielsson, Per Albin Hansson och KG Westman mot Ture N

The estimation of structure and motion from image sequences using corresponding points, lines, conics and structured patches is treated. Recent research has provided good tools for obtaining good initial estimates of structure and motion using point, line, conic and curve correspondences. These estimates are, however, not so accurate. It is shown how to obtain statistically optimal estimates of st

In this study we tested the relevance of the generational hypothesis, i.e. whether the era in which household members grew up matters when understanding and predicting their behaviour, on a sample of 600 Swedish households. These households participated in a survey where they answered questions about their own energy-related residential energy behaviour. The answers were analysed for differences b
