The catalytic constants of six acids (p k a ranging from 2. 6 to 8) as well as those of hydroxonium ion and water have been measured in the hydrolysis of six ethyl-substituted phenylbenzaldehyde acetals. A good Brønsted correlation is obtained for all compounds, the α coefficient ...
The transfer function of the model of imperfectly mixed tanks in series, involving the three parameters p, m and n, is presented. It is thus possible to evaluate easily the residence time distribution curve E(θ) and the output response for a given input. This model is compared to the ...
The exact solution of the Feynman checkerboard model is given both in terms of the hypergeometric series and in terms of Jacobi polynomials. It is shown how this leads, in the continuous limit, to the Dirac equation in two-dimensional space-time.J. G. Williamscanadian journal of physics...

Questions addressed were: (1) What do Indiana teachers know about their physical environment? (2) How do Indiana teachers feel about the environment? and (3) How do the teachers' responses compare to those given by teachers a decade ago? Recently certified elementary and secondary teachers were...
However, acquired, as well as de novo résistance to IM have been described in CEL. In order to further improve the treatment of HES/CEL, we investigated the effects of all-trans retinoic acid (ATRA) on the EoL-1 cell line, ...
A new formulation is presented for the delocalisation model in which the effects of environment are considered in an explicit manner. The method permits one to find the successive inversions for the selectivity of reactional sites for the 1-methyl-quinoleinium ions and for toluene as a function...
