چکیده
-The carbon dioxide produced during biological oxidation of wastewater has a pronounced influence upon the pH that is attained in the activated sludge process. The quantity produced is proportional to the COD removed, its degree of oxidation and depends also on the oxidation level of the substrate. A discussion of metabolism is given with emphasis on the description of the oxygen consumption. The theory is compared with experimental results. A mass balance for the metabolism of model compounds is presented. This model is based on a thermodynamic consideration of the metabolic process and offers a basis for calculation of R. Q. values. Experimental evidence for the applicability of this model is presented. Experimental results for a sewage are applied in pH calculations. ADP ATP COD AF/M 3/1, P/O

Abstraet--A budget model is developed to predict the long-term response of a lake to changes in its phosphorus loading. This model computes total phosphorus and hypolimnetic oxygen concentrations, taking sediment-water interactions into account. The lake is treated as two segments: the water and a surface sediment layer. A total phosphorus budget for the water accounts for inputs due to externa...

We introduce several analogs of the Robinson-Schensted algorithm for skew Young tableaux. These correspondences provide combinatorial proofs of various identities involving f&,, the number of standard skew tableaux of shape L/p, and the skew Schur functions So..,,. For example, we are able to show bijectively that and 4 S;&)QdY)=C ~p;p(x)~~,p(Y) n (1-%Y,)Y. P 1. I It is then shown that these ne...
متن کاملMacro Tree Transducers
Macro tree transducers are a combination of top-down tree transducers and macro grammars. They serve as a model for syntax-directed semantics in which context information can be handled. In this paper the formal model of macro tree transducers is studied by investigating typical automata theoretical topics like composition, decomposition, domains, and ranges of the induced translation classes. ...
متن کاملOn the editing rate of the Multiedit algorithm
In a number of previous publications, we have stated, without proof, that the total fraction of samples discarded by the MULTIEDIT algorithm is bounded f rom above by 2E I, where E l is the 1-NNR error rate for the initial distributions. It is the purpose of this note to offer a more precise formulat ion together with a derivation of this assertion.
