The liquid suspension culture of dissociated Nostoc flagelliforme cells was investigated. It was found that the growth rate of N. flagelliforme cells and the accumulation of exopolysaccharides (EPS) increased prominently when NaNO(3) and KH(2)PO(4) were added in the liquid BG-11culture medium though phosphate had little effect on EPS yield for specific mass(More)
The production of a low-temperature alkalophilic lipase from Acinetobacter johnsonii was improved using genome shuffling. The starting populations, obtained by UV irradiation and diethyl sulfate mutagenesis, were subjected to recursive protoplast fusion. The optimal conditions for protoplast formation and regeneration were 0.15 mg lysozyme/ml for 45 min at(More)
This paper proposes a new algorithm that employs Adaptive Dynamic Programming(ADP) to solve the distributed control problem of urban traffic with an infinite horizon. Urban traffic congestions lead to a lot of time consumption and exhaust emissions. So alleviating congested situation will have a good impact on both economy and environment. The signal(More)
In order to develop more potent, selective and less toxic steroidal aromatase (AR) inhibitors, molecular docking, 2D and 3D hybrid quantitative structure-activity relationship (QSAR) study have been conducted using topological, molecular shape, spatial, structural and thermodynamic descriptors on 32 steroidal compounds. The molecular docking study shows(More)
OBJECTIVE To determine whether or not there is an increased level of serum C-reactive protein (CRP), of peripheral white cell count and of associated factors in Chinese patients with polycystic ovary syndrome (PCOS). SUBJECTS AND METHODS Seventy-four patients with PCOS were recruited for the study. The control group consisted of 51 normal healthy women of(More)
In this paper adaptive dynamic programming (ADP) is applied to learn to play Gomoku. The critic network is used to evaluate board situations. The basic idea is to penalize the last move taken by the loser and reward the last move selected by the winner at the end of a game. The results show that the presented program is able to improve its performance by(More)
Previous research has demonstrated that diabetes induces learning and memory deficits. However, the mechanism of memory impairment induced by diabetes is poorly understood. Dietary fatty acids, especially polyunsaturated fatty acids, have been shown to enhance learning and memory and prevent memory deficits in various experimental conditions. The present(More)
Monitoring and assessing the effects of contaminants in the aquatic eco-environment is critical in protecting human health and the environment. The zebrafish has been widely used as a prominent model organism in different fields because of its small size, low cost, diverse adaptability, short breeding cycle, high fecundity, and transparent embryos. Recent(More)
In this paper, a novel ultra-wideband (UWB) pulse shaping method was presented to generate IR-UWB waveforms which can suppress multiple narrow-band interferences. The proposed method includes two steps. First, to completely satisfy and fully utilize the FCC power spectral density mask, an “interim-pulse” was generated by combining several(More)
