1. Modeling self-heating and dry matter loss in large-scale biomass storage
Master-uppsats, KTH/KemiteknikSammanfattning : Materialförluster och självuppvärmning är ett vanligt problem vid lagring av biomassa i stor skala. Biomassan som lagras bryts med tiden ned av mikroorganismer och kemiska processer vilket resulterar i en förlust av torrsubstans, ofta kring 1-4% per månad. LÄS MER
2. Photometry of carbon star wind-modelsat solar & sub-solar metallicities
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Asymptotic giant branch stars (AGB) are cool, luminous stars withan initial mass of approximately 0.8 to 8 solar masses. Towards theend of their lives they undergo heavy mass loss, a process thoughtto be caused by dust-driven winds. When it comes to carbon-richAGB stars, i. LÄS MER
3. Pulsation Properties in Asymptotic Giant Branch Stars
Kandidat-uppsats, Uppsala universitet/Teoretisk astrofysikSammanfattning : Asymptotic Giant Branch (AGB) stars are stars with low- to intermediate mass in a late stage in their stellar evolution. An important feature of stellar evolution is the ongoing nucleosynthesis, the creation of heavier elements. LÄS MER
4. High temperature corrosion in exhaust application for heavy-duty trucks
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. LÄS MER
5. Hampakalk - En jämförelsestudie med avseende på brandegenskaper
Kandidat-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : Lime-hemp concrete is an old insulation material, made out of hemp shiv and lime, making its way back onto the market. This thesis focuses on the usage of lime-hemp as an alternative insulation material for restoration of older wooden buildings in the town of Visby in Gotland, Sweden. LÄS MER
