An overview of the reactions involving trihalomethanes (haloforms) CHXYZ, where X, Y, and Z are halogen atoms, has been given in the context of ozone depletion (Hayman and Derwent 1997). Interest in the formation of trichloroacetaldehyde formed from trichloroethane and tetrachloroethene is heightened by the phytotoxicity of trichloroacetic acid (Frank et al. 1994), and by its occurrence in rainwater that seems to be a major source of this contaminant (Muller et al. 1996). The situation in Japan seems, however, to underscore the possible significance of other sources including chlorinated wastewater (Hashimoto et al. 1998). Whereas there is no doubt about the occurrence of trichloroacetic acid in rainwater (Stidson et al. 2004), its major source is unresolved since questions remain on the rate of hydrolysis of trichloroacetaldehyde (Jordan et al. 1999). 

Liquid flows from an upstream source, at pressure Pi, via a fixed position valve into the tank, at pressure P2. The liquid in the tank discharges via a second fixed position valve to a downstream pressure P3. The tank can be open to atmosphere, closed off to the atmosphere and can work either under isothermal or adiabatic temperature conditions. The detailed derivation of this problem is discussed both by Franks (1972) and Ramirez (1976, 1989). Data values in the problem are similar to those of Ramirez, who also made simulations of this problem. 

Although this sometimes occurs through the operation of Frank-Read sources it is not generally observed. What does generally occur is similar, but more complex. The process is called multiple-cross-glide, and was proposed by Koehler (1952). Its importance was hrst demonstrated experimentally by Johnston and Gilman (1959). In addition to its existence, they showed that the process produces copious dislocation dipoles which are responsible for deformation-hardening. 

Recapitulating the foregoing discussion, it is clearly not our opinion that solution experiments appear to be inadequate for the purpose of comparison with molecular theories. However, we want to point out that due to the evident shortcomings of present theoretical and computational facilities a distinct scepticism is necessary in order to avoid the production of meaningless data. Of course, the solution experiments remain the main source of information, the data of which must be explained by theory. At the present stage of knowledge it is only possible to pick out selected properties of solutions which can be described satisfactorily on a molecular basis. For instance, referring to Frank and Wen s model of solvation shells W, the structure of the inner shell should not be modified too much by... 

Frank-Kamenetskii first considered the nonsteady heat conduction equation. However, since the gaseous mixture, liquid, or solid energetic fuel can undergo exothermic transformations, a chemical reaction rate term is included. This term specifies a continuously distributed source of heat throughout the containing vessel boundaries. The heat conduction equation for the vessel is then...

Harriet Brooks, 1876-1933 (Mrs. Frank Pitcher). In 1902 Rutherford and Miss Brooks studied the penetrating power of a-rays from various sources and made the first attempt to determine the density of radon by a diffusion method. Their study led to the discovery of radium A, B, and C. This photograph was taken in 1898 when Miss Brooks obtained her B.A., McGill University. 

Braun and Frank (1980) reported diazinon residues in three fish species collected from a creek in southern Ontario, Canada, contaminated from a point source discharge. Tissue residues for the three edible fish species were 18 ppb in the brown bullhead (Ictalurus nebulosus), 17 ppb in the black crappie (Pomoxis nigromaculatus), and 92 ppb in the gizzard shad (Dorosoma cepedianum). The maximum diazinon concentrations measured in the contaminated creek water for 1975-76 and 1976-77 were 140 ppb (5.75 ppb mean) and 26 ppb (1.02 ppb mean), respectively.
