The possibility for obtaining a hard neutron spectrum in small reactor cores has been considered.A harder spectrum than spectra in known fast sodium cooled and molten salt reactors has been obtained thanks to the selection of relatively small core dimensions and the use of metallic fuel and natural lead (natPb) coolant.The calculations for these co
The Heimlich manoeuvre is a technique aimed at clearing the windpipe when it has become blocked by a foreign body.It is a lifesaving manoeuvre, such that since it was first described it has been considered the simplest manoeuvre (it does not require technical media) that most lives has saved in the world.Easy to learn and use, it is recommended in
The thermal-relic mechanism for the production of dark-matter in the early universe, combined with the precision measurements of the cosmic microwave background and the lack of observation of dark matter at the LHC, motivates the search for dark matter in the mass range between 1 MeV Horse Accessories and 1 GeV.We describe the concept for the Light
Abstract Background Translocation of nanoparticles (NP) from the pulmonary airways into other pulmonary compartments or the systemic circulation is controversially discussed in the literature.In a previous study it was shown that titanium dioxide (TiO2) NP were "distributed in four lung compartments (air-filled spaces, epithelium/endothelium, conne
