2. 11. Silicon Nanowire Based Sensors for Bacterial Tests

   Author : Yingtao Yu; Zhen Zhang; Mihai Adrian Ionescu; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nanowire; field-effect transistor; antibiotic susceptibility test; bacterial metabolism; nanoelectromechanical sensor; multiplexed detection;

   Abstract : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. READ MORE

4. 12. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors

   Author : Petri Henrik Murto; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solution processing; conjugated polymers; fluorescence; near-infrared; light-emitting electrochemical cell; organic photodetector; organic light-emitting diode;

   Abstract : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.

5. 13. Analysis of regional seismic data by means of higher-order spectra

   Author : Leif Persson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Abstract : The use of higher-order statistical and spectral estimators as complementary analysis for conventional regional seismic data processing is studied. The issues addressed are; the properties of the complex bispectrum of regional seismic phases, the experimental detection performance of higher-order statistical detectors, discrimination between local earthquakes and explosions, statistical tests and bicoherence, biphase and spatial bispectrum analysis of regional P-, S, and Lg-phases.

6. 14. Wind Turbine Sound Propagation in the Atmospheric Boundary Layer

   Author : Olof Öhlund; Conny Larsson; Anna Sjöblom; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind turbine sound; atmospheric effects; outdoor sound propagation; refraction;

   Abstract : Wind turbines have grown both in size and number in the past decades. The taller turbines has made it possible to place them in forest areas which is fortunate for a country like Sweden with lots of forest. An issue with wind turbines is the sound they produce. The sound mainly comes from the rotor blades when they pass through the air. READ MORE

7. 15. Space in the Space : Designing Sound Environments for the Shared Indoor Workspace

   Author : Martin Ljungdahl Eriksson; Lena Pareto; Davide Rocchesso; Högskolan Väst; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sound Environment Design; 4E Cognition; Research through Design; Design program; Sound Users; Ljudmiljö; utformning; arbetsplats; medarbetare; Work Integrated Learning; Arbetsintegrerat lärande;

   Abstract : The sound environment in shared indoor workspaces emerges through the interplay of physical layout, materials, technology, and social dynamics. These spaces are designed with specific purposes in mind, taking acoustics into account during construction. READ MORE
