Batch tests were used to compare the reduction rates of ({text{NO}}_{3}^), as the sole added acceptor, with rates of concurrently added ({text{NO}}_{3}^) and N2O.
In contrast, the tests with ({text{NO}}_{3}^) as the sole added electron acceptor had an initial ({text{NO}}_{3}^) concentration of only 50 mgN L−1.
When N2O and NO3 − were added concurrently, the apparent (extant) kinetics, (hat{q}_{text{app}}), assuming reduction to N2, were 6.3 gCOD gCOD−1 d−1, compared to 5.4 gCOD gCOD−1 d−1 for NO3 − as the sole added acceptor.
For these tests, as well as for the previous tests with ({text{NO}}_{3}^) as the sole added acceptor, we determined apparent (extant) parameters (hat{q}_{app}), (Y_{app}) and (hat{mu }_{app}).

"Our commitment is to give 100% coverage by 2016, but that can only happen with a big investment of 5bn soles," she adds.
This is managed with a simple Shuform slipper (Salts Healthcare, Birmingham, England) to which a layer of foam (which strengthens the sole) and a non-slip rubber sole are added.
This model used mean parent diameter as the sole predictor; adding the mean deflection angle did not improve performance.

However, he adds, "The sole obstacle remaining to resolving the status of same-sex binational couples is DOMA.
