Using MMd. calculate A H and. V leading to ATT and t his reaction has been the subject of computational studies (Kar, Len/ and Vaughan, 1994) and experimental studies by Akimoto et al, (Akimoto, Sprung, and Pitts. 1972) and by Kapej n et al, (Kapeijn, van der Steen, and Mol, 198.V), Quantum mechanical systems, including the quantum harmonic oscillator, will be treated in more detail in later chapters.

Schampel and Steen (1975) describe experimental equipment and tests carried out at the Physikalisch-Technische Bundesanstalt (PTB) in Germany on high velocity vent valves. Also, conditions for a sufficient air entrainment and dilution of the vented flammable vapors are discussed.

Human data as well as studies in animals have provided negative evidence of carcinogenicity for endosulfan (Hack et al. 1995 Hoechst 1988b, 1989a). However, endosulfan promoted the development of altered hepatic foci in rats initiated with nitrosodiethylamine (Fransson-Steen et al. 1992). Although the mechanism of tumor promotion of endosulfan is not known, it has been suggested that it involves inhibition of cellular communication (Kenne et al. 1994). A brief discussion of this topic is provided in Section 2.5 under Cancer Effects.
