In the present investigation, we successfully employed a cell-free extract of Esteya vermicola CNU 120806 to convert ginsenoside Rg3 to Rh2. Three important factors including pH, temperature and substrate concentration were optimized for the preparation of Rh(2). The optimal condition was obtained as follows: 50°C, pH 5.0 and substrate concentration of 3 mg(More)
In this study, the lipoxygenase (ana-LOX) gene from Anabaena sp. PCC 7120 was successful expressed and secreted in Bacillus subtilis. Under the control of the P43 promoter, with a signal peptide from the B. subtilis 168 nprB gene, and facilitated by the molecular chaperone PrsA, the production of the recombinant ana-LOX (ana-rLOX) reached 76 U/mL (171.9(More)
In this paper, we present a voxel-based collision detection method for clothed human animation. We speed up the pe$ormance of the voxel-based method by choosing an appropriate voxel size and using a fast voxelization approach. Based on the voxel method, we propose a selfcollision detection method and a simplijied collision detection method. First, the(More)
Eulaliopsis binata, which is a close relative of cereal crops, was recognized as an important research material owing to its high frequency of apospory and autonomous endosperm formation. However, little information is known about its genomics and regulatory pathway participating in reproductive development. For the first step to understand molecular basis(More)
Understanding the factors that affect residents' waste separation behaviors helps in constructing effective environmental campaigns for a community. Using the theory of planned behavior (TPB), this study examines factors associated with waste separation behaviors by analyzing responses to questionnaires distributed in Guangzhou, China. Data drawn from 208(More)
With the advance in virtual reality applications, garment industry has strived for new developments. This paper reviews state-of-the-art CAD methods in 3D garment design. A large range of techniques are selected and organized into several keymodules which form the core of a 3D garment design technology platform. In each module, basic techniques are(More)
EasyToy is an industrial plush toy design system for novices. Editable sketching curves combine the advantages of free-form strokes and the controllability of B-spline curves. Users can continuously edit each curve to refine designs. EasyToy provides a small set of simple tools with which users can easily construct sophisticated toy models comparable to(More)
