From industrial past to sustainable future : Arboretum Lövholmen; generating trees for a greener future
Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society.
We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen.
Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress?
The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.
Biomassauttag vid delkvistat sortiment i klen gallring
The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect.
Trees were harvested and divided into bunches based on diameter.

Integrerade ledningssystem : Drivkrafter, möjligheter och hinder
The world is changing and the business context is no exception. One of the clearest tendencies is a tougher business climate with harder competition due to increased international trade and the expansion of the e-business. At the same time the customers are becoming more sophisticated and demanding. The last decades have also meant that tougher and more frequent demands are being aimed at the businesses from a wider variety of stakeholders; demands regarding how environmental issues, social responsibilities and business ethics should be dealt with. All of the above have driven companies towards implementation of different management systems to be able to cope with the demands as well as to ensure that these issues are being dealt with in an efficient and effective manner.
Effekt av biotintillförsel på klövhälsan hos mjölkkor i lösdrift : ett kontrollerat fältförsök på tre gårdar
The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study.
The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.
Aktinos : genomgång av aktinosproblematik hos nötkreatur
Actinomycosis is a rare, deep-seated infection of the jaw of cattle that include the progressive enlargement of bone structures. It is caused by Actinomyces bovis, a gram-positive rod found as a normal commensal of the alimentary canal in otherwise healthy animals. This paper shortly describes Actinomyces bovis and its ability to cause "lumpy jaw" or actinomycosis in cattle. It will describe its pathogenesis, diagnosis, treatment and some clinical presentations. The incidence of symptomatic actinomycosis infection is quite low in Sweden today.
PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT
This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.
Patientupplevelser vid brachyterapi mot prostatacancer
Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.
Rimbo våtmark : en förstudie på förväntad kväveavskiljning och lämplig växtlighet
This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
Strålbehandling på hund och katt :
Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours.
The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.
??trevlig först och sedan kan man prata om det sakliga...? En studie om bemötande på folkbibliotek.
The purpose of this thesis is to investigate the view on the personal encounter between staff and visitors in public libraries in order to detect possible differences between the two groups in order to see if the personal encounter as such could be used in order to market libraries. We believe that social competence must interact with the initial personal encounter in order for the visitor to experience the visit as positive. We have based the theoretical framework on Erving Goffman?s theory on social interaction, as well as on Christian Grönroos? theory on quality of service and marketing. We use the following questions: How do library staff view the personal encounter? How do library visitors view the personal encounter? How does the library staff?s treatment affect the visitor?s view of the library?Are there any differences in view between visitors and staff concerning the personal encounter? If so, what kind of differences are they? Using qualitative interviews, we have interviewed nine visitors and six staff members at two public libraries.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?
Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
