The electronic cigarette: a knight in shining armour or a Trojan horse?†
Electronic cigarettes have caused a sharp debate in the public health community, with some promoting them as a means of harm reduction for tobacco users and some taking a strong stand against them because of fear of renormalising smoking behaviour and interrupting tobacco control progress. People with mental health problems smoke at high rates and e-cigarettes seem a potentially attractive meth...
متن کاملUser's Knights in Shining Armour?
The aim of this article is to address the relation between a usercentred objective and social constructionism and the possibility to refine usercentred fundamentals by enhancing the awareness of the relation between humans and the constructed environment. Through social constructionism we could enter a bit deeper into questions like; (1) reality’s subjective character especially concerning tech...
متن کاملBallistic Impact on Ceramic/aramid Armour Systems
The ballistic performance of the lightweight armour systems was examined to obtain an estimate for the V50 and the global damage of the composite plates. All estimates were performed by varying the thickness of ceramic tiles, while maintaining equal areal density of the system. Simulation predictions and trial results is demonstrated both in terms of deformation and damage of the laminates and ...
متن کاملIs behind armour blunt trauma a real threat to users of body armour? A systematic review.
INTRODUCTION Behind armour blunt trauma (BABT) has been defined as a non-penetrating injury caused by the rapid deformation of body armour. There has been an increasing awareness of BABT as an injury mechanism in both the military and civilian worlds; whether BABT results in serious injuries is debatable. METHOD A systematic review of the openly accessible literature was conducted using the P...
متن کاملMaterials design principles of ancient fish armour.
Knowledge of the structure-property-function relationships of dermal scales of armoured fish could enable pathways to improved bioinspired human body armour, and may provide clues to the evolutionary origins of mineralized tissues. Here, we present a multiscale experimental and computational approach that reveals the materials design principles present within individual ganoid scales from the '...
