Black liquor (BL) is a notoriously difficult wastewater to treat due to the economic and efficiency limitations of physiochemical methods and intrinsic difficulties with bioremediation strategies caused by the high pH (10–13) and lignin content. This study investigated the feasibility of a novel bioaugmentation strategy for BL treatment, which uses a mixed(More)
There is no commercial or industrial-scale process for the remediation of black liquor using microorganisms to date. One of the most important causes is that most microorganisms are not able to use lignin as their principal metabolic carbon or energy source. The bacterial strain Comamonas sp. B-9 has shown remarkable ability to degrade kraft lignin and(More)
The problem of optimal vibration control for vehicle active suspension systems under road roughness disturbance is considered. First, the models for two-degree-freedom quarter-car suspension system under road roughness disturbance are presented, and road disturbances are considered as the output of an exosystem. Then, the feedforward and feedback optimal(More)
OBJECTIVE To compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN). METHODS One hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform(More)
OBJECTIVE To evaluate the psychometric properties of the 6-item Kessler psychological distress scale (K6) in screening for serious mental illness (SMI) among undergraduates in a major comprehensive university in China. METHOD The K6 was self-completed by 8289 randomly sampled participants. A group of them (n=222) were re-assessed using K6 and interviewed(More)
This paper studies the vibration control problem for systems with delayed state under persistent disturbances. In order to simply the vibration control problem for system with delayed states, a free-delayed-state method is proposed to reform the original problem into an equivalent optimal regulate problem with delay-free ones. Then, an approximate optimal(More)
