1. 16. Fragmented landscapes : Assessment and communication of landscape connectivity in human-dominated landscapes

   Författare :Arvid Bergsten; Örjan Bodin; Bo Ebenman; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fragmentation; Connectivity; Network; Spatial; Landscape; Dispersal; Planning; Social-Ecological; Scale; IIC; STS; naturresurshushållning; Natural Resources Management;

   Sammanfattning : This licentiate thesis summarizes the first half of my PhD on the theme of management of fragmented landscapes. The thesis applies – and reflects on the use of – network analysis of connectivity in relation to landscape planning. LÄS MER

3. 17. Seeing the invisible: Evolution of wing interference patterns in Hymenoptera, and their application in taxonomy

   Författare :Ekaterina Shevtsova; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chalcidoidea; parasitic wasps; structural colors; visual signaling; cryptic species; sexual dimorphism; wing membrane thickness; wing micro-morphology; wing cuticle ultrastructure;

   Sammanfattning : The remarkably thin transparent wing membranes in tiny wasps may appear to have a simple structural design, but hide a largely unexplored complex of micro-morphological features that serve aerodynamics and may also function in visual signaling. I found that when such small transparent wings are viewed against a dark background they display vivid structural color patterns due to thin film interference, and named them Wing Interference Patterns (WIPs).

4. 18. Signal Processing Techniques for Detection of Buried Landmines using Ground Penetrating Radar

   Författare :Håkan Brunzell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

   Sammanfattning : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. LÄS MER

5. 19. Fluorescent thiophene-based ligands for detection and characterization of disease-associated protein aggregates

   Författare :Therése Klingstedt; Peter Nilsson; Per Hammarström; Henrik Zetterberg; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : In this thesis the unique optical properties of fluorescent ligands termed luminescent conjugated oligothiophenes (LCOs) have been used to study a variety of protein aggregates associated with human protein misfolding disease. This heterogeneous group of diseases contains well known and fatal members such as Alzheimer´s and Huntington´s disease and the development of sensitive tools for the detection and characterization of protein aggregates is crucial for unravelling the complexity of these pathologies.

7. 20. Optical Imaging and Spectroscopy of Metal Nanostructures

   Författare :Juris Prikulis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; surface plasmon resonance; surface-enhanced Raman spectroscopy; near-field optical microscopy; optical tweezers;

   Sammanfattning : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. LÄS MER
