Folkbibliotekariers användning av sökverktyg på webben i referenstjänst
The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.
Effektiv materialstyrning i en försörjningskedja
Syftet med detta examensarbete är att analysera och utvärdera olika material styrningsmetoder inom tillverkningsindustrin för att få konkurrensfördelar. Scania som var uppdragsgivare ville att vi konkret skulle titta på vad som kan främja deras produktion.

Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :
Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden.
The purpose of the study was to attain a greater knowledge about CCF practices.

Avgörande faktorer för talnaturlighet hos personer med Parkinsons sjukdom : Korrelationsstudie mellan naiva lyssnares bedömning och akustisk analys
Tal- och röstförändringar är vanligt förekommande hos personer med Parkinsons sjukdom. Dessa påverkar ofta talarens förståelighet men kan också ha en negativ inverkan på talets naturlighet. Forskning angående vilka faktorer som påverkar talets naturlighet är i dagsläget begränsad, varför föreliggande studie har genomförts.Syftet med studien var att undersöka huruvida den uppfattade talnaturligheten kunde härledas till några specifika tal- och röstparametrar. I föreliggande studie konstruerades ett testbatteri för att elicitera talmaterial från åtta personer med Parkinsons sjukdom. Forskningspersonernas röster spelades in och inspelningarna graderades sedan av 27 naiva lyssnare gällande förståelighet och talnaturlighet.
Tillämpning av GIS-analyser i MKB
The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.
Dried distiller?s grains with solubles and Swedish grown soya beans as protein feeds for dairy bull calves
The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.
Byggkostnader inom mjölkproduktionen - jämförelse av olika stallstorlekar och byggnadstekniska utföranden
Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building.
Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table.
Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year.
Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Att utvärdera vetenskapliga tidskrifter: En kritisk analys av Journal Impact Factor: en metod inom citeringsanalys.
The purpose of this Masters thesis is to make a critical analysis of Journal Impact Factor JIF. JIF is today the most widespread quantitative measure for evaluating scientific journals. Although it is internationally used and is considered authoritarian many problems have been observed. This has led to that the validity of JIF has been questioned. To identify JIFs limitations the following issues have been raised: Which are the problems with citation analysis? What criticisms have been directed towards Journal Impact Factor as a measure for evaluating scientific journals? The theoretical framework consists of theories about citation behaviour and a discussion about the characteristics of a scientific journal.

Parasitering på en expanderande art : har kartfjärilen undkommit sina naturliga fiender?
Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.
