Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

The empirical data used for this master thesis, consists of eight manuals with the main purpose to help students evaluate information resources found on the web or Internet. The purpose is to elucidate the discourses and investigate those textual characteristics, which figure in the investigated manuals. The method used is a discursive and linguistic approach, with a power/knowledge discussion applied to the results. The analysis identifies, among other things, the production and consumption of the investigated texts, and that the manuals function as a reflection of the relationship between the participants in the situation, the sociocultural practice of the institution and its identity..

Huvudmålet med examensarbetet var att konstruera en utrustning för mätning samt loggning av dieselförbrukning på en buss. Det fanns dessutom en önskan att ett MOST-nätverk skulle konstrueras. Detta skulle användas på 2005 år Formula SAE-bil vid Luleå tekniska Universitet. Olika metoder diskuterades och arbetet resulterade i en prototyp som mäter och loggar både bränsleförbrukning och körsträcka på Luleå Lokaltrafiks bussar. Även ett mindre MOST-nätverk upprättades men med ett icke tillfredställande resultat.

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.

In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.

In this study, we have explored a new area called ?gamification? ? a word and concept that was first introduced on the Internet autumn 2010. Gamification concerns integrating game design, with emphasis on game mechanics and game dynamics, into non-gaming contexts ? such as marketing. At its basic definition, it concerns the process of transforming all kinds of activities into games.

Particular to the cat among our pets is its´ unique nutritional needs and metabolism. The cat cannot produce some nutrients by themselves and must get them through their diet. This means that the cat quickly can suffer from various diseases unless the nutritional needs are covered. In those cases where man is completely in control of the cat?s diet, the right knowledge is crucial for the cat?s wellbeing.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
