Vill EU vända på steken? : En kritisk analys av EU-kommissionens ställningstagande i frågan om animalieproduktionens klimatpåverkan
This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.
Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.
Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter
The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.
GROT-transport från norra till södra Sverige
The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.
Hållbar konsumtion av nötkött och mjölk
Sustainable beef and milk consumption. The consumption of beef and dairy products in Sweden is high. A lot of greenhouse gases are emitted from the production of these products. The production of beef in Sweden has decreased but the import has increased. The number of dairy cows has decreased while beef-production with suckler-cows has increased in Sweden.
Hur bemöts barn i det virtuella biblioteksrummet? : En socialsemiotisk bildanalys av fyra folkbibliotekswebbsidor.
The purpose of this master's thesis is to examine how the public library communicates with young users through the library web sites. Four Swedish public library web pages for children are analysed. In the analysis the web pages are treated as a combination of semiotic resources that, communicating as a whole, hold a meaning potential. In order to identify the underlying meaning of the whole I have applied the tools of Kress' & van Leeuwen's visual social semiotics to the chosen web pages.The information value, the framing and the salience of each composition is examined and analysed, as is the size of frame, the perspective and the vertical angle of a selection of images from each web page. The results of the semiotic analysis are then discussed and related to Jochumsen et al:s four space-model and the notion of ?child perspective? and ?empowerment?.The results show that the child perspective is strongest on the web pages that represent the performative space as dominating and that empowerment is mainly represented as ?doing?, ?participating? and the ?free choice?.
Adaptiv stämning : En bedömning av acceptabilitet och tonkvalitetsuppfattning
This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with.

Svampar associerade med raps : betydelse för uppkomst och grödetablering
Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems.
This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens.
The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.
Solenergisystem i Hammarby Sjöstad
Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
Foderhäckar till hästar i lösdrift :
Knowledge about feed racks for feeding forages to horses is lacking. Racks for sheep and
cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales
with the plastic and net still on, can bring on a lot of different problems. The opportunity to
control the hygienic quality is small and feed losses can be high.
The purpose of this experiment was to investigate how the eating behaviour and consumption
of horses were influenced by feeding racks of different constructions. Feed losses and changes
in chemical composition of the forage were also studied.
Politisk kommunikation och IKT : En analys ur politikernas perspektiv i Västerås kommun
The purpose of this paper is to see how politicians use Internet communication in their daily work and how they use it to interact with citizens of Vasteras city. To reach my conclusions I used both theoretical methods such as literature studies and qualitative interviews with the towns 11 trustees. Accoarding to this study the politicians saw not only a lot of potentials and advantages in Internet communication but also many difficulties and obstacles. In this case the cons far exceeded the pros. One of the main reason is the bad experiences which caused by rasist attacks/threats made to politicians and also the difficulties in handling of sensitiv documents which was seen as a stress factor.
Koldioxidsutsläppsbesparing vid biogasproduktion
Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.
Fysträning för ishockeyspelare
To become a successful athlete requires several different components in which one of themost significant is the ability to develop their own physical strenght. What weight exercises has the best transfer effects for skating?Participants in the study were 20 male senior hockey players from Div. II in the Västra Gö- talands Regionen in which all participants had at least 10 years of hockey experience.Test subjects had to perform a five-minute individual warm up followed by an opportunity to familiarize with the upcoming exercise. The first on-ice test was a 35 meters sprint test and the second test was an S-cornering agility test.
Narrativ för arenaspel : att skapa ett narrativ till ett ?mutiplayer Online Battle Arena? koncept
In 2011, I and fellow student at Gotland University created a multimedia game. To fit the time constraints a ?vertical slice? was created. This means a small sample of the game is taken which allows the user to understand how the game works, and at the same time, get a visual demonstration of how the game is designed. The goal of the project was to create a narrative for stadium games in which the backstory is told as players interact with their surroundings.
