1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER
2. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. LÄS MER
3. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/FREIASammanfattning : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. LÄS MER
4. Determine how estrogen and TNFα impact circadian clock genes in colorectal cancer (CRC) cells
Master-uppsats, KTH/ProteinvetenskapSammanfattning : Kolorektalcancer är den tredje vanligaste cancerformen i världen. Hormonet östrogen har visat sig ha skyddande effekter och i tjocktarmen förmedlas dess effekt av östrogenreceptorn β (ERβ). LÄS MER
5. Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. LÄS MER
