The aim of the project was to investigate if Swedish rodents, brown rat (Rattus norvegicus), house mouse (Mus musculus), wood mouse (Apodemus spp) and water vole (Arvicola terrestris) captured in pig herds and in urban areas, constitute a reservoir for pathogenic Leptospira spp. Under Swedish conditions leptospirosis gives rise to reproductive disorders in pigs and symptoms of flu in humans. It has long been established that rodents are chronic carriers of pathogenic leptospires in their kidneys, and can spread the bacteria with urine. The old nomenclature of serovoars is still in use, but a new system of genetic classification has developed and today the genus Leptospira contains 17 species. There are several diagnostic test developed for leptospirosis.
Klövviltets besöksfrekvens och bete i sydsvenska poppelplanteringar
Energy is an essential part of the society and for a sustainable future we need to use the energy resources in a sustainable way. The forest is Sweden?s most important resource for renewable energy and a higher production combined with shorter rotation periods (time from planting to clear cutting) can increase the access to energy. The tree genus poplar (Populus spp.) is interesting as energy resource as it has both high production and short rotation period.
But browsing ungulates are a major threat to the establishment of poplar plants and therefore the poplar plantations need to be fenced in today. To use fences is expensive and time consuming; this makes it interesting to find more cost-effective solutions where there is no need to fence.
The aim with this study was to look at the ungulates? occupation rate and browsing pressure in poplar plantations without fence.
Stormskador i lärk och gran : en jämförelse efter stormen Gudrun
The storm Gudrun January 8-9 2005 felled about 70 millions cubic metres forest in southern Sweden. The majority of the wind damaged forest was spruce (Picea abies). In order to decrease the risk of wind damages in the future other trees species are of interest for forestry in southern Sweden.
The purpose of this master thesis was to study if larch were more wind tolerant than spruce. The method was to compare larch, Japanese larch (Larix kaempferi Lamb.), European larch (L.
Folkbiblioteket och postmoderniteten en hermeneutisk studie av debatten om folkbiblioteket i DIK Forum 1998-2002
The main issue of this master is to investigate what influence the phenomenon of postmodernity has on the Swedish public library. Is it possible to talk about the Swedish public library as postmodern, and if so, is it expressed by a postmodern discourse? The concept of postmodernity is defined as an open and inclusive value system where all kind of opinions and preferences take place. According to a postmodern point of view there is no such thing as an objective or general truth. A postmodern ideology does not talk about reality but about realities.

Skaftslamkrypa (Elatine hexandra) i Bolmen, utbredning, tillväxt, reproduktion och styrande faktorer
The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.
Naturvärden i Killingeskogen : Biologisk mångfald och friluftsliv
Killingen is an area situated on an island called Resarö in the municipality of Vaxholm. The areais covered with forests with a varied topography and a mosaic of environments. The municipalitywants to keep the area unexploited, for recreational purposes but what are the natural values inthe forests? The survey concluded that a mosaic of nature types had high values and could behosts for vulnerable species.As part of the study, measures that will improve the quality of the paths and bathing areas for thelocal population was proposed as well as means to heighten or preserve the natural values in thearea..
Är gnagare reservoar för patogena leptospiraarter i Sverige?

Revolution eller krig? : Hur Arbetaren, Folkets Dagblad, Ny Dag och Socialdemokraten ramade in slutet av spanska inbördeskriget
The purpose of this paper is to understand how different fractions of Sweden?s left wing (the Social democrats, the Communists, the Syndicalists and the Socialist party) framed the end of the Spanish Civil War and the defeat of the republicans.To answer the purpose four newspapers Arbetaren (syndicalist), Folkets Dagblad (Socialist party), Ny Dag (communist) and Socialdemokraten (social democratic) have been analyzed qualitatively. The thesis has focused on how the different ideologies have framed the war, how they framed the other labour organizations and themselves plus how they relate to information about the war during the period of February 1st1939 till April 5th1939.The analysis shows that the Social democrats and the Communists framed the war as a conflict between fascism and socialism, whereas the Syndicalists and the Socialist party framed the war as a socialistic revolution. Because each side had their own view, their opinions on what threatened a republican victory differed. The Social democrats were most concerned that a non-democratic movement would win the war and the Communists feared that fragmentation within the republicans would threaten their chances to win.
Debatterna om En bok för alla år 1992 och 2007 ? En diskursanalys

Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :
During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.
Rör inte mitt bibliotek! Om nedläggningshotade filialbibliotek i den lokala dagstidningsdebatten.
The aim with this Master's thesis is to study the debate that takes place in the local community when a public library branch is threatened by closedown through the local newspapers. Through this it is our aim to understand why the debate takes place, and why so many people gets concerned with it. By relating this debate to contemporary research of library- and information science, and the discussion in three major Swedish library journals, we have found the answers to these questions. By studying the debate, we found six subjects that where essential for this study. These were Politics and economics, Urban and rural districts, Democracy and accessibility, The service of the library, The meeting place and To replace a closed down library.
Inventory and evaluation of Nairobi Animal Orphanage : focusing on spotted hyena, serval, Sykes' monkey, vervet monkey and on educational elements
The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.
