Validering av vattenkraftmodeller i ARISTO
This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.
Barn söker i bibliotek ? en kunskapsöversikt
The aim of this thesis is to investigate new knowledge about how children search for library material and which strategies they use, and if the latest research gives any answers whether we should adapt systems and services or teach information seeking in a better way. In this thesis knowledge is understood as research publications but also results from projects in library practise, and studies concerning children 6 to 18 years old are included. The method used is a knowledge survey. We have gathered and evaluated documentation from different sources like citation and reference databases within the field of library and information science. The result implicates that there are, both in old and new documentation, three main search strategies children use in their search for information in a library context; they browse, they search in library catalogues and they use some sort of reference service.
En bild säger mer än tusen ord. En studie om hur unga tjejer och killar talar om droger
The aim of this study is to examine how young people look at and perceive drugs by studying how they discuss and reason about drugs. The essay's main interest is not whether young people use drugs or not. We are primarily interested in how young people talk about drugs. The questions that we want to get answered are:What are the beliefs that young people have about drugs, drug use and drug users? More specifically we seek answers to which images, symbols and attributes that young people links to drugs, drug use and drug users.What is important in young people's construction of beliefs about drugs and drug users? More specifically, which are the information sources and reference groups that young people assigns significance?We used focus group interviews as the research method.
EN JÄMFÖRELSESTUDIE AV PLAST- OCH GLASHEMOCYTOMETRAR FÖR BERÄKNING AV BLODCELLER I VENÖST OCH KAPILLÄRT HELBLOD
Hematology-instruments that analyze blood cells can at specific cases
be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.
Aktivering av en dissolvingmassa med enzymer före en konventionell viskosprocess
In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.
Dysartribedömning på svenska av typiska talare över 65 år med finska som förstaspråk
The aim of this paper was to investigate how 40 typical speakerswith Finnish accent, aged 65-84 years, performed in speech assessmentthrough Dysartribedömningen, a Swedish dysarthria assessment instrument.Their results were compared with results of a matched Swedish nativespeaking reference group. Both groups were assessed in areas offunction/structure, prosody/intelligibility and through a survey oncommunication. Results indicated that the performances of the Finnishparticipant group were estimated as more deviant than the Swedish,considering all areas. The Finnish participants were deviant in articulationand they had a significantly lower speech rate in reading. They also hadsignificantly lower scores in intelligibility compared to the reference group.The results of the survey of communication showed that the Finnishparticipants estimated their levels of activity and participation to besignificantly more limited compared to the reference group.
Högre allmänna läroverket i Falun : Ett ordnings- och förteckningsarbete
The text deals with the process of reorganizing and cataloging the archival material emerging from State secondary grammar school in Falun, which appears to have been poorly managed for a number of years. The work was done with consideration to former ways of organizing the material, and a great deal of research was needed in order to establish the outer provenance of the archive.The theoretical discussion goes deeper into the questions of provenance and appraisal in regard to the work,and some choices, especially the decision to reorganize the archive, are motivated with reference to Swedishrules and regulations concerning state authorities' archival management and their duties towards Swedish citizens..
Användaren och den elektroniska referenstjänsten

Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..

25 år senare : en nyinventering av keramiken på Ajvide
This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated ?dark areas?, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis.
