4. 3. Road traffic noise reduction by multiple scattering and absorption mechanisms

   Författare :Bart van der Aa; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outdoor sound propagation; Sonic crystals; Road traffic noise; FDTD; Noise barriers; MST; Porous materials; 2.5D MST; Graded index sonic crystals;

   Sammanfattning : Millions of people in Europe, and even more on a global scale, are affected by environ- mental noise. Traffic related noise is estimated to cause a yearly loss of approximately one million healthy life years in Western Europe, which is mostly related to road traffic noise. LÄS MER

5. 4. Graded index sonic crystal noise barriers: An introduction to design and optimization

   Författare :Bart van der Aa; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shape optimal design; Broadband acoustic lens; Optimization; Outdoor sound propagation; Sonic crystal noise barrier; Graded index sonic crystal;

   Sammanfattning : Environmental noise pollution and its impact on human beings remains to be an important topic in acoustics. Conservative estimations of the World Health Organization have shown that traffic related noise alone causes a loss of approximately one million healthy life years, only within Western Europe.

7. 5. Deposition and Resolution of AA Amyloid

   Författare :Sofia N. Nyström; Gunilla T Westermark; Christoph Röcken; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AA-amyloid; autophagy; resolution; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

   Sammanfattning : Amyloidosis is a group of protein misfolding diseases characterized by extracellulardeposition of fibrillar protein aggregates. Today more than 25 different human amyloidogenicproteins have been identified, causing a variety of pathological conditions that includeAlzheimer’s disease, type 2 diabetes and prion diseases. LÄS MER
