1. Growth of Silver birch (Betula pendula) & Downy birch (Betula pubescens) established in four different initial densities on one site in central Sweden
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Nowadays, there is an increased demand for timber resources and more sustainable forest management, starting from the establishment phase of the forest, e.g., planting. Depending on the management goals, number of seedlings planted and thus initial spacing can be adjusted in order not to waste resources. LÄS MER
2. Finite Element Modeling of Installation Effects of Soil-Cement Columns
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. LÄS MER
3. Planteringsförbandets inverkan på slutavverkningsbeståndets utseende och kvalitet
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Med förband menas hur långt avstånd det är mellan plantor eller träd i ett bestånd. Förbandet kan variera mellan olika ytor beroende på vilken typ av bonitet marken har. Vid hög bonitet kan det planteras fler plantor än på ytor med sämre bonitet, vilket gör att planteringskostnader också varierar från bestånd till bestånd. LÄS MER
4. Transient modeling of a high temperature borehole thermal energy storage coupled with a combined heat and power plant
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : Coupling High-Temperature Borehole Thermal Energy Storages (HT-BTES) with existing Combined Heat and Power (CHP) systems is a promising approach to increase energy efficiency of district energy systems through recovery of otherwise wasted heat. This solution is currently being discussed in Sweden by the company Tekniska Verken in Linköping AB, for storing waste heat from their CHP operation in summer in a HT-BTES and to utilize it during peaks in winter.

5. Fabrication and characterization of nano/micrometer glass channels with UV lithography
Magister-uppsats, Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : In this project, fabrication and characterization of nano/microfluidic channels on borosilicate glass substrate were carried out using a Photo/Ultraviolet (UV) lithography method, which has applications in single-cell analysis. In our single-cell analysis glass system, the bacterial cells will be made to sit in the micrometer channels and also the sub-micron size channels around 300 nm is aspired so it helps in passing the fluid to the outlet hole while holding the cells back.
