Abstract: The present disclosure provides a method for rapid and harmless treatment of a livestock and poultry carcass/residue by a bacterium-enzyme complex and relates to the technical field of dead livestock and poultry treatment. In the present disclosure, a composite microbial inoculant is compounded from protease-, lipase-, and keratinase-producing strains, and can be applied to the degradation of fats and proteins as well as deodorization. The composite microbial inoculant is further combined with a protease preparation and a lipase preparation to prepare the bacterium-enzyme complex. The bacterium-enzyme complex can quickly and harmlessly treat the carcasses/residues of pig, cattle, sheep, and chicken, and has a short treatment period, mild and controllable reaction conditions, and safe and non-toxic reaction process and reaction products. During the reaction, harmful gases such as CH4 and NH3 and greenhouse gases such as CO2 released by the method are less than those by other methods.

Abstract: Physimetric-based data security for coded distributed temperature sensing (DTS) in which physimetric information is extracted from a coded-DTS interrogator which is unique for each interrogator at each operating run time—and used to reconstruct a final temperature determination from DTS data. The physimetric information includes coded-DTS pulse code and coded-DTS pulse profile information as a key to permit secure sharing with authorized users. The pulse code and pulse profile information are encrypted and made available to an authorized user. The authorized user can then decrypt the pulse code and pulse profile information and subsequently use this key information (pulse profile and pulse code files) to retrieve temperature information from for example, a remote computer providing a continuous raw data feed—without being susceptible to eavesdropping.

Abstract: Provided are a cell strain HEK293.CS for reducing the production of a replication competent adenovirus, and a construction method and the use thereof. HEK293.CS is a safe adenovirus-producing cell line constructed by knocking out a gene fragment homologous to the Ad5 adenovirus E1 gene in HEK293 and providing a template plasmid to replace said gene fragment with a non-homologous sequence that stabilizes the expression of the E1 gene. Compared with the unmodified HEK293 cell strain, HEK293.CS shows no decrease in growth ability and virus production ability, but does not produce a detectable RCA. HEK293.CS can be used for the mass culture of a recombinant human type 5 adenovirus, and reducing the probability of RCA production in the manufacture process of drugs such as vaccines and antibodies.
