Abstract: An active infrared thermography system and a computer-implemented method for generating a thermal image are provided. The active infrared thermography system includes one or more excitation sources, an infrared camera, one or more portable power sources arranged to power the one or more excitation sources and the infrared camera, and a housing, the one or more excitation sources and the one or more portable power sources being received in the housing.

Abstract: The present invention relates to a method for expressing antimicrobial peptide CAD by means of a recombinant Bacillus subtilis expression system. The SUMO protease expression operon is first artificially synthesized. The protein expression operon genes of Saccharomyces cerevisiae small ubiquitin-related protein is then fused with the antibacterial peptide AD. The fusion protein is further cloned into the pNF11 plamid to be introduced into Bacillus subtilis, thereby ensuring the induced expression of recombined Bacillus subtilis in shake flasks. The method has the advantages of a simple expression system, large-scale production, low production cost, strong biological activity and no toxic or harmful substance production. Moreover, the method provides a medicine with low price and strong antibacterial capacity for clinic disease prevention and treatment. This invention can also be used as a feedstuff additive.
