Gårdssmedjor i södra Gästrikland En studie av Hedesunda och Österfärnebo socknar
Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys
The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010.
More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.
Torrfoder till katt : påverkan och konsekvenser
The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.
Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.
Värmesystemsutveckling
In cooperate with Asko Cylinda we have developed a new heat system too short the process
time and reduce the energy consume in a dishwasher and still have it too be a class AAA.
The environment and quality is important for the company too still be the number one on
the market, If they want too keep that position the product developed of new innovations will
be very important. The systems we have developed are more effective and reduce energy up
too 25 %. The process time is reduced too less than two hours, from the today two and
half-hour. The solutions are too heat up the rinse water and the dishwater at the same time,
with a new heating system and it make are solutions unique and effective. Its good for the
dish and the environment.
Analys av massapumps- och mixerarbete vid Metsä Board Sverige AB, Husums Fabriker : Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning
Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.
Informativa strukturer och egenskaper som stöd för automatiska processer i människans informationshantering
The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.
Beacons & Internet of Things : A design concept for contect-aware mobile interaction with beacons
Mobile technology is developing quickly and becomming a part of daily life and communication. Bluetooth Low Energy is presented as a new way of mobile interaction. However there are not enough studies in this field on the interaction between mobile devices and the physical world. In order to understand user needs, and to encourage users to interact, we simulated an interaction process through designing and testing a prototype in a specific indoor environment. Prototype effectiveness and main characteristics for future mobile application was evaluated through a qualitative user study with 20 participants who interacted with our prototype..
Biogasproduktion genom tvåstegsrötning av drankvatten
During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.
Majstorkning :
The corn plant came to Europe with Christopher Columbus in the 14th century and have
ever since bin cropped here, but corn haven?t bin very common in Scandinavia until
recently. The mainly use for this crop silage but even corn for grain is cropped in
Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden
corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen
Sverige is the biggest buyer of corn at the moment.

Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
