1. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER
2. Analysis of Microgrid Electrification on Phaluai Island : A Minor Field Study in Thailand
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Similar to numerous other nations, Thailand aims to achieve carbon neutrality by 2050 by reducing reliance on fossil fuels and increasing the amount of renewable energy sources in electricity generation. The objective of the Thai Provincial Electricity Authority (PEA) is to ensure electricity access for all Thai households and villages. LÄS MER
3. Numerical Design of an Extremely High Temperature Thermochemical Reactor for Converting Biochar to Hard Carbon
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Hard carbon is now a popular choice for the anode material in sodium-ion batteries. Converting biochar to produce hard carbon is considered carbon neutral and of great interest since it reduces the environmental impacts of biomass waste. LÄS MER
4. 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
5. Reindeer decrease soil carbon stocks and deplete labile soil carbon
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.
