Abstract: A multiple impeller type power generation turbine includes a body, at least a high pressure water tank, and two impellers, two first jet assemblies and two low pressure steam chambers installed in the body. The high pressure water tank is provided for containing a working fluid coming from a fluid source. The two impellers are synchronously and rotably linked with the power generator. The two first jet assemblies is provided for ejecting the working fluid contained in the high pressure water tank to fluid inlet ends of the two impellers and guiding the working fluid from the fluid outlet ends to the two low pressure steam chambers to drive the power generator to generate electric power, so s to improve the power generation efficiency and modularization and the convenience of installation and maintenance.

Abstract: A flexible ligand docking method based on evolutionary algorithms is provided. The proposed method incorporates family competition and adaptive rules to integrate decreasing-based mutations and self-adaptive mutations to act as global and local search strategies, respectively. The invention is to provide a method for screening and evaluating conformationally flexible ligands as potential lead compounds, because the method can be applied to search space for possible configurations of ligands in order to correctly dock into the active site of an enzyme. Therefore, the proposed method can be used to guide drug-design strategies and explore evolutionary relationships. Furthermore, the method of this invention has implications for protein engineering and protein folding.
