3. Tricresyl phosphate - Wikipedia

   en.wikipedia.org/wiki/Tricresyl_phosphate

   The most dangerous isomers are considered to be those containing ortho isomers, such as tri-ortho-cresyl phosphate, TOCP.The World Health Organization stated in 1990 that "Because of considerable variation among individuals in sensitivity to TOCP, it is not possible to establish a safe level of exposure" and "TOCP are therefore considered major hazards to human health."

4. Dilution ratio - Wikipedia

   en.wikipedia.org/wiki/Dilution_ratio

   The "dilution factor" is an expression which describes the ratio of the aliquot volume to the final volume. Dilution factor is a notation often used in commercial assays. For example, in solution with a 1/5 dilution factor (which may be abbreviated as x5 dilution ), entails combining 1 unit volume of solute (the material to be diluted) with ...

5. Spin isomers of hydrogen - Wikipedia

   en.wikipedia.org/wiki/Spin_isomers_of_hydrogen

   The ratio between numbers of ortho and para molecules is about 3:1 at standard temperature where many rotational energy levels are populated, favoring the ortho form as a result of thermal energy. However, at low temperatures only the J = 0 level is appreciably populated, so that the para form dominates at low temperatures (approximately 99.8% ...
