   methodology;

   Abstract : For decades the focus of civil protection has been on civil defence shelters to withstand the threat of warfare and protecting civilians. In latter years, the general focus has often shifted towards the protection of specific targets that host functions important to society. READ MORE

4. 2. Concrete Structures Subjected to Blast Loading

   Author : Jonas Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; numerical modelling; spalling; blast load; stain-softening; wave propagation; concrete; transverse reverse loading; cyclic crack propagation;

   Abstract : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. READ MORE

6. 4. Human olfaction : Associations with longitudinal assessment of episodic memory, dementia, and mortality risk

   Author : Ingrid Ekström; Jonas Olofsson; Maria Larsson; Devangere Devanand; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; olfaction; odor identification; self-assessments; aging; episodic memory; ApoE; dementia; Alzheimer’s disease; vascular dementia; mortality; cohort study; population-based.; Psychology; psykologi;

   Abstract : A declining sense of smell is a common feature in older age. Above and beyond diminished smelling capacity due to normal processes of human aging, impairments in olfactory function have also been linked to numerous ill-health related outcomes, such as cognitive dysfunctions, dementia pathology and even an increased risk of death.

7. 5. High performance breath alcohol analysis

   Author : Jonas Ljungblad; Mikael Ekström; Olof Lindahl; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Abstract : Alcohol breath testing on a larger scale will save lives. Alcohol intake affects the human body by significantly longer response time to external stimuli. READ MORE
