Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Att man ska leva och äta hälsosamt för att hålla sig frisk och må bra är de flesta människor medvetna om. Trots detta har förekomsten av kostrelaterade välfärdssjukdomar ökat de senaste åren och fler och fler människor drabbas av ätstörningar av olika slag. Media påverkar samhället att tro att dieter, snabb viktnedgång och bantning är hälsosamt samtidigt som kakor, godis och Chips framställs som något bra bra. Många människor börjar nu förstå att media inte alltid har rätt och intresset för att äta sund och hälsosam mat har ökat i Sverige. Som kostrådgivare har man till uppgift att öka människors förståelse för vad som är nyttig och hälsosam mat och ge dem råd kring deras kosthållning.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood Chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-Chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood Chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production. Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy. The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.

Syfte och frågeställningarSyftet med studien var att undersöka om Body Mass Index (BMI), metabola tillstånd, fysisk aktivitet och intag av energitäta livsmedel skiljer sig mellan individer med mycket stillasittande tid respektive individer som tillbringar mindre tid stillasittande. För att besvara syftet ställs följande frågeställningar:Skiljer sig de metabola variablerna BMI, blodtryck, blodfetter och blodsocker hos individer som tillbringar mycket tid stillasittande jämfört med individer som tillbringar mindre tid stillasittande?Skiljer sig intag av energitäta livsmedel så som Chips, jordnötter, tårtor, wienerbröd, choklad och glass hos individer som tillbringar mycket tid stillasittande jämfört med individer som tillbringar mindre tid stillasittande?Hur påverkar fysisk aktivitet och stillasittande risken för övervikt när hänsyn har tagits till confoundrar (så som, kön, ålder, utbildningsnivå och intag av energitäta livsmedel)? MetodData har hämtats från studien LIV 2000 där syftet var att samla information om motionsvanor, fysisk prestationsförmåga och levnadsvanor bland svenska kvinnor och män i åldrarna 20-65 år. En kvantitativ arbetsmetod har använts genom enkäter och fysiologiska tester som sedan har bearbetats genom statistikprogrammet SPSS för att sammanställa resultatet. Studien baserades på totalt 1067 personer, varav 603 personer valde att endast svara på enkäten och 464 personer genomgick både de fysiologiska testerna samt svarade på enkäten. ResultatResultatet visade att den enda signifikanta skillnaden mellan stillasittande och aktiva individer av de metabola variablerna var BMI som var högre hos de stillasittande.

The sludgebark and to a certain extent the bark were until a decade ago waste products without any economic value that were thrown away. A number of environmental laws and increcing energy prices have improved the prerequisites for increasing the use of these materials. At Seskarö sawmill they burn the sludgebark and a great deal of the bark in the sawmill furnace. The sludgebark has a number of disadvantages compared to bark during burning. The sludgebark is often wet which means the energy net from burning often gets low.
