The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.

A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

The effects of Reindeer mechanical damages on the planted regeneration of Pinus sylvestris and Pinus contorta. Semi-domesticated reindeer can damage young trees. In late winter reindeer rub their antlers against young trees. The aim of this study was to quantify those damages. This study covered planted objects from three different areas in northeastern Sweden.

Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

Uppsatsen kommer reflektera kring vad som gör ett spel till en e-sport med fokus på tre huvuddelar inom e-sport idag. Detta baseras på Klines, Peuters och Dyer-Withefords teori om Three Circuits of interactivity; Teknik, Marknadsföring och Kultur. Dessa tre delar utgör e-sport.Alla spel som finns på marknaden idag är tävlingsinriktade och går ut på att lösa problem, men alla spel är inte e-sporter och det finns även spel som försvunnit från scenen. Vi ville undersöka hur detta var möjligt. Vilka faktorer är det som gör att vissa spel bli e-sporter?Vi samlade information under DreamHack Vinter 2011 från flera källor inom e-sport.

Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

The ability of dairy cows to survive and the economic importance of this have been in-creasing in dairy cattle breeding lately. Increased longevity contribute to an increased pro-portion of cows that produce milk in more productive lactations and reduces the replace-ment costs together with a good health and fertility. Unfortunately it is often argued that longevity has been decreasing due to a strong selection for production traits in dairy cattle.The aims of this study were to find correlations between different longevity evaluations and between different estimates on longevity and other traits in the Nordic Total Merit (NTM) breeding value. The aim was also to compare different traits for cows of two differ-ent longevity groups.The data were Predicted Breeding Values (PBV) from Nordic HOL and SR bulls and records from Holstein (HOL) and Swedish Red (SR) cows estimated by the Swedish Dairy Association.The three Swedish longevity indexes were very highly correlated (>0.89) and the corre-lations between the Swedish official longevity index and the five Nordic Cattle Genetic Evaluation (NAV) longevity indexes varied between 0.73-0.83.In the sire evaluation part, the traits most negatively correlated with longevity for HOL were dairyness, protein and fat index. In SR, milk, protein, and fat index only had slightly positive correlations with longevity.

This master thesis was conducted at Motala Wire Works Ltd (MWW) in Motala during the autumn and winter of 2007-2008. The thesis named ?Future layout of Motala Wire Works? focuses on making a better planed layout for the factory, which also take in to consideration future changes.Motala Wire Work produces wire mesh products of varying sorts for the white goods industry. The factory was started by Electrolux during the 1950?s.

Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.
