Food waste is converted into animal food by feeding it to insects and then processing the insects into animal food. Biological hazards that may be present in the food waste, the insects, or both is reduced by treating, preferably with superheated water. Data related to the food waste and the insect crops is maintained in a database, allowing for process monitoring and control, and tracking, especially in the case of a food-borne illness that may have contaminated the food waste.

A chemical / biological hazard protection suit has two pants legs which extend to a midsection below waist level. An opening in the midsection defines an outlet from the suit interior. A waste collector has an upper segment which is fixed to the midsection and which adjoins an intermediate segment which is in turn connected to a waste receptacle. A first seal is between the upper segment and the intermediate segment, and a second seal is between the intermediate segment and the waste receptacle. A region of weakened material encircles the intermediate segment between the seals. A wearer discharges waste through the outlet and past the two open seals into the receptacle, whereupon both seals are closed, and the receptacle is detached from the upper segment, leaving both the receptacle and the suit sealed. Prior to use, the waste receptacle may be retained within a pocket on one of the pants legs.

A method is provided, the method comprising operating a field emitter array (FEA) to generate at least one of a high electric field and a high electron flux, and exposing the field emitter array (FEA) to at least one gas. The method further comprises generating at least one radical species from the at least one gas exposed to the at least one of the high electric field and the high electron flux.

A mail container with a contaminant indicator mechanism in the form of a perimeter edge viewing window is provided for verifying that a mail item received does not contain a biological hazard in the form of a loose particulate such as powders, granules, and the like. In order to attract the attention of the mail recipient that particulate matter may be contained in a mail container, an area having a quantity of clear, adhesive on only a portion of one or more of the transparent perimeter edge viewing windows so that the mail recipient or delivery person could immediately identify the existence of particulate matter contamination.

Apparatus and method for detecting and identifying hazardous material in a mail stream in which hazardous particulates or material in or on mail pieces in a mail stream are detected and the mail piece bearing the hazardous material is identified. A bar code applicator applies a unique bar code to the wrapper of each mail piece identified as potentially containing hazardous material. The bar code applicator is an ink jet which applies the bar code on-the-fly. The bar code applied is encoded with specific information about the detection parameters at the time of the event in addition to specific information about the date, time of day, machine identification, temperature and humidity conditions, etc. present at the time of the event.

The invention relates to an unexpected biological event field hazard evaluation simulation system, which comprises an information receiving module, a hazard preliminary evaluation module, a GPS module, an information storage module, a hazard calculation module, and a hazard display module. The information receiving module is used for receiving biological hazard data of a hazard field; the hazard preliminary evaluation module is used for calculating the maximum hazard depth, hazard width and hazard area of pathogenic microorganisms; the GPS module is used for positioning a geographical pathogenic microorganism-polluted area on a national administrative map; the information storage module is used for storing the national grid population data; the hazard calculation module is used for transferring the grid population data inside the geographical pathogenic microorganism-polluted area from the information storage module and calculating the number of infected people and ill and dead people after infection; and the hazard display module displays the geographical pathogenic microorganism-polluted positioned by the GPS module and the number of infected people and ill and dead people after infection calculated by the hazard calculation module on the national administrative map. The unexpected biological event field hazard evaluation simulation system can be widely applied to emergency treatment of a biological hazard attack event.

The invention relates to an arborescent polypeptide for conducting a cell therapy on HPV infection. The arborescent polypeptide is characterized by being formed by connecting four carboxyl groups of a C-terminal of an HPV epitope peptide with three amino groups of a poly-L-arginine framework composed of arginine residues, wherein an amino acid sequence of the epitope peptide is Tyr-Met-Leu-Asp-Leu-Gln-Pro-Glu-Thr-Gly-Gly-Gly. The invention further provides a screening method, a preparation method and application of the arborescent polypeptide. Through design and analysis of multiple kinds of combined bioinformatic software, the capacity of finding a new epitope is improved, the epitope loading orientations achieve consistency, and the specific combination capacity and reaction sensitivity of the epitope peptide are exponentially improved in unit space. The epitope peptide is single in structure and property and has the great advantages of being high in specificity, free of potential biological hazards and capable of achieving stardardization in preparation process.

The invention discloses a detection method and device of stored grain biological hazards. The detection method of the stored grain biological hazards comprises the specific steps that S1, a moisture value RH, a temperature T and a carbon dioxide concentration value CO2 of a grain pile are collected, and the grain moisture content Mc and a stored grain microbial prediction value F are calculated; S2, whether CO2 is less than 1000ppm or not is judged, if so, the safety of stored grain is determined; if not, S3 is transferred; S3, whether RH is less than or equal to 65% or not is judged, if so, the existence of pest hazards is determined and pest alarming is carried out; if not, S4 is transferred; S4, whether the RH is less than or equal to 75% or not is judged, if so, S5 is transferred; if not, S6 is transferred; S5, whether T meets a temperature preset condition or not is judged, if so, ventilation alarming is carried out; if not, the S6 is transferred; and S6, the microbial hazard grade is judged based on F, the insect mold activity hazard grade is judged based on CO2, and the stored grain biological hazard grade is judged though comprehensive microbial hazard grade and insect moldactivity hazard grade and the corresponding alarming is carried out. The detection method can judge and alarm the stored grain biological hazards in time and accurately.

The invention, which belongs to the biological hazard prevention and control field, relates to a biological hazard monitoring, predicting and optimal controlling system for emergency (BMPOSE). The system is the Internet of things and connects two subsystems which comprise: a biohazard emergency monitoring system (BEMS) and a biological hazard predicting and optimal controlling system for emergency (BPOSE). The BEMS and the BPOSE carry out coupling and relevance of information through the Internet of things and complete the control of the biological hazard through data processing in the Internet of things. The system combines information acquisition, transmission, analysis, prediction and issuing. By using the system, technical difficulties of seamless coupling, such as emergency monitoring, predicting, decision support and the like, can be solved.
