2. 1. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts

   Author : Per Henningsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apus apus; aerodynamics; animal flight; kinematics; vortex wake; digital particle image velocimetry; DPIV; common swift; tracking radar; wind tunnel; migration; roosting flight;

   Abstract : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. READ MORE

4. 2. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?

   Author : Malin Lager; Anna J. Henningsson; Peter Wilhelmsson; Per-Eric Lindgren; Andreas Matussek; Fredrik Elgh; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Lyme borreliosis (LB) is caused by spirochetes within the Borrelia burgdorferi sensu lato complex and is the most common tick-transmitted disease in the northern hemisphere. The transmission of the spirochetes to humans in Europe is done by the Ixodes ricinus ticks, which can also transmit the relapsing fever species Borrelia miyamotoi. READ MORE

5. 3. Stochastic Event-Based Control and Estimation

   Author : Toivo Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

   Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

6. 4. Content and Distribution of Short-Chain Fatty Acids in the Hindgut of Rats Fed Various Sources of Indigestible Carbohydrates

   Author : Åsa Henningsson; Avdelningen för livsmedel och läkemedel; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; red kidney beans; Nutrition; Näringslära; oligosaccharides; non-starch polysaccharides; resistant starch; dietary fibres; indigestible carbohydrates; short-chain fatty acids; fermentation;

   Abstract : There is increasing evidence that short-chain fatty acids (SCFA) formed by colonic fermentation of indigestible carbohydrates have beneficial physiological effects. Butyric acid is the main energy substrate for the colonic mucosa and has been implicated as important in the prevention and treatment of diseases of the colonic mucosa, such as distal ulcerative colitis and cancer.

7. 5. Environmental preferences among steel stakeholders

   Author : Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

   Abstract : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. READ MORE
