4. 17. Chronic Obstructive PulmonaryDisease : Early detection and prevention in primary care

   Author : Georgios Stratelis; Sigvard Mölstad; Per Jakobsson; Olle Zetterström; Kjell Larsson; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Background and aims. Early detection of Chronic Obstructive Pulmonary Disease (COPD) and secondary prevention by means of smoking cessation are the only available methods of stopping the progression of the disease. The overall aim was to examine the possibilities of early detection and prevention of COPD in General Practice. READ MORE

   Abstract : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

6. 19. Exploring Polymer-Shelled Microbubbles: Detection Modeling and Application

   Author : Hongjian Chen; Dmitry Grishenkov; Birgitta Janerot-Sjöberg; Tomas Jansson; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound contrast agent; polymer-shelled microbubble; ultrasound imaging; contrast pulse sequence; microbubble model; hydrodynamic cavitation; Technology and Health; Teknik och hälsa;

   Abstract : Ultrasound imaging (US) is widely used in clinical practice. Given the low cost and easy access to the ultrasound machine, US has a great potential to improve the health care condition for the majority of the population in the world. The US could be significantly improved by injecting ultrasound contrast agents to opacify the bloodstream. READ MORE

7. 20. Damage and defects in railway materials: influence of mechanical and thermal damage on crack initiation and propagation

   Author : Casey Jessop; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : With rising societal concern for the environment, railways offer travelers a sustainable alternative to other forms of fossil-fueled transportation. In order to be competitive with airlines, for example, the railway industry must provide safe, efficient, and affordable service. READ MORE
