COMPARATIVE GENOMIC ANALYSIS REVEALS EVIDENCE OF TWO NOVEL VIBRIO SPECIES CLOSELY RELATED TO V. CHOLERAE




Efficiency of the chimney effect controlling radon levels indoor

According to the WHO the radioactive gas radon must be controlled indoors.E.g.by naturally driven suction systems based on thermal buoyancy, also denoted the chimney effect, which exploits the difference of indoor- and outdoor temperature to lower radon levels indoor.This paper presents four case studies showing that the efficiency of such systems
