… and the test cell is described. Results from the tests are presented covering emissions, heat release and pressure traces from the DDF-concept. During the literature study it was found that most research was related to heavy duty diesel engines. The research papers covered in …
effekt på mjölkavkastning och betesbeteende hos mjölkkor
… spent grazing and ruminating. Since ruminating animals give rise to methane emissions, methane emissions from the different feed ratios were estimated using equations obtained from the literature. In the trial 27 lactating dairy cows (Swedish Red Breed) were blocked by parity …
effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable …
… methods that is the base in our thesis. The amount of energy use or the emissions are not analyzed for neither the Swedish road administrations nor Svevias construction models. Our thesis has compared these two models of constructing a road to evaluate what affects the climate …
Överföring från väg till järnväg
Road transports stand for a great part of Sweden’s total CO2-emissions. Transports are expected to increase over the coming years, and with those the emissions. A greater environmental awareness leads to increased demands for environmentally friendly transport. The aim of this …
By using steady-state measurements for predicting emissions under a dynamic drive cycle would save a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea for this thesis has been to investigate if statistical regression models can be used with …
… In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The …
Under 2009 lanserade Lantmännen handel med emissionsinsatser och emitterade förlagsandelar. Handeln med emissionsinsatser syftar till att behålla emissionsinsatserna i Lantmännen, då många av medlemmarna är äldre och kommer att begära utträde ur föreningen kommande år. Handel …
Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
… of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat …
Analys av framtida energisystem
… agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy …
… a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed. This is done in order to provide an answer to whether the proposal is a viable solution to the transport issue in the north?eastern Stockholm area …
… been considered. The conclusion gives an account on savings of carbon dioxide emissions, energy, and capital. The capital savings will act as a foundation on which the size of investment will be proposed with the aid of economic calculations.The results show that an …
… technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the …
