Cavitation in cryogenic liquids is widely present in contemporary science. In the current study, we re-examine a previously validated acoustic cavitation model which was developed for a gas bubble in liquid water. Furthermore, simulations of cryogenic fluids including the thermal effect, the effect of acoustic pressure amplitude and the frequency of sound field on the bubble dynamics are presented
Over the last decade the anti-corruption movement, led by the Berlin-based NGO Transparency International (TI), as grown to include 90 affiliates throughout the world. While pursuing laudable goals to raise awareness about corruption, promulgate and enforce anti-corruption conventions, pursue anti-corruption projects and embarrass corrupt governments thorugh its Corruption Perception Index and Bri
This paper reports on an explorative test session performed at INPG during December 2005. During this session two different implementations of a virtual PebbleBox were explored freely. The purpose of this test was to explore the importance of different pa
The paper concerns the issue of how prayers were used by the laity in late medieval Scandinavia. Often prayers were used, not only to communicate with God, but also to avoid fear and illness.
Leukocyte recruitment is a rate-limiting step in inflammatory disease. Tissue accumulation of leukocytes is a multi-step process comprising leukocyte rolling, adhesion and transmigration across the vascular endothelium. The aim of this thesis was to investigate the mechanisms underlying ischemia-reperfusion (I/R)-induced leukocyte-endothelial cell interactions in the colon. For this purpose, intra
SI Engine knock is caused by autoignition in the unburnt part of the mixture (end-gas) ahead of the propagating flame. Autoignition of the end-gas occurs when the temperature and pressure exceeds a critical limit when comparatively slow reactions - releasing moderate amounts of heat - transform into ignition and rapid heat release. In this paper the difference in the heat released in the end-gas
Force feedback (FF) devices will bring us new ways to interact with computers. The game industry is starting to create sophisticated devices that enable users to feel virtual objects and movements. For people with visual disabilities, this might be even m
