1. Leave no trace: A non-destructive correlative approach providing new insights into impactites and meteorites
Sammanfattning : Impact cratering is today recognized as a fundamental geological process on all rocky bodies in the solar system. On Earth, however, processes such as plate tectonics and erosion have eradicated most craters from the geological record, or they may be buried under sediments, oceans, and vegetation. LÄS MER
2. Ultrahigh-Voltage Silicon Carbide Device Performance, Requirements, and Limitations in High-Power Applications
Sammanfattning : The increased awareness of the on-going climate change accelerates the electric energy system transformation from fossil-fueled power sources towards systems with larger portions of renewable energy sources. Moreover, the grid infrastructure requires reinforcements to cope with increasing electrical energy demand. LÄS MER
3. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins
Sammanfattning : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. LÄS MER
4. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features
Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.

5. Efficiency and wear properties of spur gears made of powder metallurgy materials
Sammanfattning : Powder metallurgy (PM) is usually used in manufacturing parts with complex geometries, such as gears and structural parts. The main attractions of PM are the high rate of material utilization, environmental friendliness of production, economic advantages (especially for complex geometries), and possibility of obtaining lighter components.
