Food and feed contamination by aflatoxin (AF)B₁ has adverse economic and health consequences. AFB₁ degradation by microorganisms or microbial enzymes provides a promising preventive measure. To this end, the present study tested 43 bacterial isolates collected from maize, rice, and soil samples for AFB₁-reducing activity. The higher activity was detected in… (More)
This paper presents an avoidance strategy for the robot to find the optimal trajectory to reach the target point in a complex environment. First, The robot's movement function is presented from the following three aspects. The first is that the robot motion must be in designated areas; the second is that the robot can reach the target location by the… (More)
—CAI plays a more and more important role in education by introducing the technology of artificial intelligence and knowledge of engineering. Pivotal technology and purpose for application of ICAI based on web are discussed in this paper. The methods of composition and realizing are also analyzed and a possible model of ICAI is set up.
