In indoor spaces, lighting control systems are highly effective to reduce electric lighting use. Daylight harvesting systems (DHS) promise to deliver the greatest energy savings. This article presents a review about DHS based on recent scientific and technical literature. The review shows that the energy saving potential of DHS lies between 20-60% in comparison with non-dimmed installations. Howev

Popular Abstract in Swedish Självmord och självmordsförsök orsakar mycket lidande för många människor i vårt samhälle. I Sverige begår ungefär 1800 personer självmord varje år. De flesta av dessa personer hade vid tiden för självmordet en psykisk sjukdom. Man har funnit att åtminstone hälften av dessa personer hade en depressionssjukdom, minst en fjärdedel hade alkoholproblem och c:a 5% led av schA suicide attempt is one of the most powerful predictors of eventual suicide. The aim of this thesis was to investigate the social situation, including social support of suicide attempters. One part of the investigations concerned patients admitted to a psychiatric ward following a suicide attempt. Another part concerned significant others (SOs) of suicide attempters, interviewed directly after th

A committee has to address a complex question, the answer to which requires answering several sub-questions. Two different voting procedures can be used. On one procedure, the committee members vote on each sub-question and the voting results then are used as premises for the committee’s conclusion on the main issue. This premise-based procedure (pbp) can be contrasted with the conclusion-based pr

Popular Abstract in Swedish Tillväxthormon (GH) är ett hormon som produceras och insöndras stötvis från hypofysen. GH-insöndringen styrs av stimulerande och hämmande signaler från hypothalamus, men hämmas även av sin egen insöndring. GH produceras under hela livet men mängden insöndrat hormon sjunker med stigande ålder. Under barn- och ungdomsåren har GH en viktig funktion att stimulera längdtillvA risk for premature atherosclerosis and increased cardiovascular mortality has been reported in adult patients suffering from growth hormone deficiency (GHD) and receiving conventional hormone substitution without growth hormone (GH) replacement. GHD patients are resistant to insulin, which is a potential risk factor for cardiovascular mortality. Insulin resistance can develop from an unfavourabl

The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accurac

The generalized Pareto distribution (GPD) is a two-parameter family of distributions which can be used to model exceedances over a threshold. We compare the empirical coverage of some standard bootstrap and likelihood-based confidence intervals for the parameters and upper p-quantiles of the GPD. Simulation results indicate that none of the bootstrap methods give satisfactory intervals for small s

Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. This thesis deals with the running in aspects to avoid high stress variation that leads to fatigue wear and the aspect of what happens to indentation damages that occurs on the surface if there are any particles in the lubricant. The pa

This paper describes the distribution of accusative case and discusses the nature of the nominative / accusative distinction in the standard Germanic languages. In addition, it illustrates and discusses the well-known fact that inherent accusatives and certain other types of accusatives do not behave in accordance with Bruzio’s Generalization. In spite of these Non-Burzionian accusatives, there is

New Information Systems Development Methodologies (ISDMs) are suggested in the belief that their deployment would be beneficial to consultants in their work. A large number of ISDMs already exist but their value has been questioned and at the same time new methodologies continue to be introduced in an attempt to support and improve the practice of information systems development work.
