The microbial biodegradation of simulated graywater, containing 21.5 mg of linear alkylbenzene sulfonate liter-1, was investigated with a continuous-flow bioreactor with 100% biomass recycle. Low concentrations of organic matter in the ultrafiltration eluate were achieved by hydraulic residence times as short as 1.6 h and for periods of up to 74 days at a(More)
The transition in physiological state was investigated between a carbon-limited chemostat population and microbes growing very slowly in a biomass recycle reactor. The mixed microbial population was metabolizing a mixture of biopolymers and linear alkylbenzene sulfonate, formulated to represent the organic load in graywater. Biomass increased 30-fold during(More)
We study CP -violation in resonant three-body Bd → DPP decays, where PP stands for either D̄π, D̄K, ππ or πK. Analogously to the Bd → 3π channel and the extraction of 2α, the first three channels are shown to measure cos 2β in addition to sin 2β, thus allowing to resolve the β → π2 −β ambiguity, while the DπK final state leads to a measurement of 2β+γ. As(More)
From sum rules in the heavy quark limit of QCD, using the non-forward amplitude, we demonstrate that if the slope ρ2 = −ξ(1) of the Isgur-Wise function ξ(w) attains its lower bound 3 4 (as happens in the BPS limit proposed by Uraltsev), the IW function is completely determined, given by the function ξ(w) = ( 2 w + 1 )3/2 .

We study CP -violation in resonant three-body Bd → DPP decays, where PP stands for either D̄π, D̄KS , ππ or πKS . Analogously to the Bd → 3π channel and the extraction of 2α, the first three channels are shown to measure cos 2β in addition to sin 2β, thus allowing to resolve the β → π2 − β ambiguity, while the DπKS final state leads to a measurement of 2β +(More)
To help the difficult determination of the angle γ of the unitarity triangle, Aleksan, Dunietz and Kayser have proposed the modes of the type KD s , common to Bs and B̄s. We point out that it is possible to gain in statistics by a sum over all modes with ground state mesons in the final state, i.e. KD s , K D +, K D s , K D s . The delicate point is the(More)
A novel graywater treatment system consisting of an aerated batch reactor and biomass-retaining ultrafiltration unit was evaluated for treatment of shipboard wastes. The focus of this study was to determine the resilience of the biomass recycle reactor to perturbations of sodium hypochlorite, the major component of bleach. A bench-scale reactor was(More)
We extend the formalism of Leibovich, Ligeti, Steward and Wise for the 1 2 − → 32 + form factors to the 12 − → 3 2 − transitions in the 1/mQ expansion of Heavy Quark Effective Theory. We show that the corresponding subleading 1/mQ magnetic coupling at zero recoil is related to the tensor force that describes the mixing between D (
, in contradiction with experiment. The same trend follows also from a sum rule for the subleading 1/mQ curent matrix element correction ξ3(1). The problem is made explicit in relativistic quarks models à la Bakamjian and Thomas, that give a transparent physical interpretation of the latter as due, not to a L · S force, but to the Wigner rotation of the(More)
