· *Note: Conversion factor CF was determined with "n" = 2.7 [ten Berge et al. 1986]. Other animal data: The median effective concentrations to produce incapacitation EC 50 s in rats have been determined to be 139 ppm and 115 ppm in 15 and 30 minutes, respectively [Hartzell et al. 1985]. Other human data: It has been reported that 45 to 54 ppm can be tolerated for 0.5 to 1 hour without ...read more
188.8.131.52.2 Progress in Reduction Part. In conventional steelmaking processes, CO 2 gas is generated when iron ore is reduced with CO gas. On the other hand, with reduction H 2 O gas is generated instead of CO 2, and therefore this method can be regarded as an environmentally friendly steelmaking process. Conventional BF-based ...read more

The presence of germination-inhibiting substances in plants seems to be a wide-spread phenomenon. They occur in all parts of plants —in fruit pulp, fruit coats, endosperm, seed coat, embryo, leaves, bulbs and roots. They are non-specific in their effects. Besides inhibitors, high osmotic pressure and acid pH are often partly responsible for the germination inhibition caused by sap, juices ...read more
cyanide, liquid weighs 0.6875 gram per cubic centimeter or 687.5 kilogram per cubic meter, i.e. density of cyanide, liquid is equal to 687.5 kg/m³ at 20°C 68°F or 293.15K at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 42.9192 pound per cubic foot [lb/ft³], or 0.3974 ounce per cubic inch [oz/inch³] .read more
