Highly purified fatty acid synthetases of chicken and rat livers have molecular weights of 500,000 and dissociate in solutions of low ionic strength into subunits of molecular weight 250,000 with loss of synthetase activity. The subunits can be reassociated in phosphate buffer with full restoration of the activity. In the presence of sodium dodecyl sulfate or guanifine-HCl, the synthetases diss...

We combine earlier treatments for the embedding of body-fixed coordinates in linear molecules with the close-coupling formalism developed for atomdiatom scattering and derive a hamiltonian which is most convenient for describing the nuclear motions in van der Waals complexes and other non-rigid systems comprising two polyatomic fragments, .4 and B. This hamiltonian can still be partitioned in t...

The entry-into-force of the Chemical Weapons Convention (CWC) on April 29, 1997, marked the beginning of the operation of the Organization for the Prohibition of Chemical Weapons (OPCW) in The Hague, the Netherlands. This organization consists of three major bodies: the Conference of State Parties (CSP), the primary policymaking forum comprising all member-states; the 41-country Executive Counc...
