  • present
  • A determination was also made of the presence or absence of both volatile and nonvolatile N-nitroso compounds which might be present in various bulk samples of chemicals used in the dye process, as this relates to worker exposure. (cdc.gov)
  • Further aspects of the present invention are a process for polymerizing ethylenically unsaturated monomers, novel initiator compounds and their use for polymerization, intermediate compounds and also the polymer or copolymer produced by this process. (freepatentsonline.com)
  • The present invention relates to a polymerizable composition comprising a) at least one ethylenically unsaturated monomer and b) a nitroxide initiator compound. (freepatentsonline.com)
  • groups
  • These compounds arise from the nitrosating of amide or amine groups during malt production or by bacteria during fermentation. (brewlab.co.uk)
  • Additional layers may be applied, including amine-providing groups such as N-trimethylsilyl-allylamine, polyoxyalkylene tethers, and bioactive compounds. (google.co.uk)
  • degree
  • Thus, these models can be used for setting testing and developmental priorities, obtaining additional information on given compounds, and, to a lesser degree, determining what substructural factors are most involved in a particular toxicological effect. (springer.com)
  • ways
  • Nitroglycerin was later adopted as a commercially useful explosive by Alfred Nobel , who experimented with safer ways to handle the dangerous compound after his younger brother, Emil Oskar Nobel , and several factory workers were killed in an explosion at the Nobels' armaments factory in 1864 in Heleneborg , Sweden.
