The invention discloses a cold-chain logistics remote monitoring system and method based on the Internet of Things. The system comprises a sensing layer, an edge computing gateway and a cloud platform. The sensing layer is provided with a multi-dimensional sensor group which at least comprises a high-precision temperature and humidity sensor, a vibration sensor, an inclination sensor, a door magnetic sensor, an electronic lock and a position tracking module and is used for collecting environment, equipment and position information in real time. And the edge computing gateway performs format conversion, exception filtering and validity verification on the original data, and triggers a local response operation according to a preset rule. The preset rules comprise data verification, sensor diagnosis, threshold linkage, data supplementary transmission and a real-time response function. The cloud platform integrates early warning grading, closed-loop management, data storage and prediction analysis functions, and adjusts parameters or early warning risks in advance based on a modeling result. The system realizes intelligent monitoring and quick response of the whole process of the cold chain, and is suitable for the fields of food, biological agents, medicines and the like with strict temperature control requirements.

The invention provides an insecticidal composition containing flurala and bacillus thuringiensis G033A and application of the insecticidal composition. The equivalent volume ratio of flurala to bacillus thuringiensis G033A is 9: 1-1: 9 (converted into that the weight ratio of effective components is 1: 100-1: 31638), and preferably, the equivalent volume ratio is 5: 5, 6: 4, 7: 3, 8: 2 and 9: 1. The composition disclosed by the invention has an obvious synergistic effect, the use amount of a biological agent can be reduced, and the prevention and treatment cost is reduced; meanwhile, the use amount of chemical pesticides can be reduced, and the harm to the environment is reduced. The generation of drug resistance of lepidoptera pests such as plutella xylostella and cnaphalocrocis medinalis can be delayed.

Method and system for the demilitarization of conventional ammunition of all types and calibers as well as chemical and biological weapons in which takes place the automated detection of each type via an Artificial Intelligence (AI) system, their instantaneous destruction and the immediate separation of the chemical-biological agent, the explosive material and the metallic mass within a co-rotating pulsed vortex environment under controlled electromagnetic field, which is applied by entering into a specialized feeding apparatus (1), a bipolar rotational vortex chamber (2), a metal parts separator (3), a metal mass processing unit (4), a configured annular drainage and separation apparatus (5), an electric arc unit (6), an off gases treatment unit originating from the electric arc unit, a gaseous pollutants treatment unit (8), a closed-loop type A and B emulsion supply-recycling system and a emulsion treatment system via E / M pulse application (111), while the whole operation is controlled by a control and operation unit (9).

The invention discloses an iron powder coating for rice seeds directly seeded in workmanship, which comprises a rice seed body, the rice seed body is coated with an iron powder substrate layer, a water-sensitive bubble disintegration layer and a fungal spore active layer in sequence from inside to outside, and rice seed composite coated pellets are formed. Trichoderma fungi or endophytic fungi are selected as beneficial strains of the fungal spore active layer, and the problem that chemical agents and biological agents are incompatible is solved.

The present technology provides a threshold sensing device including an inductor, a ferroelectric varactor, and a resonator sensitive to a selected parameter of interest. The unbiased varactor has a memory window that grows proportionally with the partial switching of the varactor's ferroelectric domains. A DC voltage is generated across the varactor which, above a parameter threshold sensed by the resonator, drives the ferroelectric switching of the varactor. A nonvolatile shift in a radio frequency readout signal serves as a memory of an exceeded parameter threshold detected by the resonator. The sensor device can be used to detect temperature violations in a cold chain or the presence of a chemical or biological agent and is capable of battery-less operation.

A process of preparing a bioformulation includes the stages of preparing air conditions having least contamination for the making of the bioformulation; preparing the bioformulation in the enclosure while maintaining air conditions having least contamination; and initiating enrichment of the bioformulation using cloths.

The process utilizes raw materials that are easily available. The bioformulation of the present invention is useful for bioremediation.

The utility model discloses a proportioning device for an insecticidal and degerming biological agent, which relates to the technical field of proportioning devices and comprises a box body, a motor and a mixing shaft, the mixing shaft is rotatably and obliquely arranged on the box body, an output shaft of the motor is connected with a driving gear, and the mixing shaft is fixedly connected with a driven gear meshed with the driving gear; according to the utility model, the unique revolution and rotation combined motion mode of the mixing shaft enables the mixing blades to stir raw materials in all directions and at multiple angles, so that the innovative design greatly improves the mixing uniformity, and ensures that the raw materials with different densities, particle sizes and properties in biological agents are in full contact and are uniformly mixed; the accuracy and the stability of the preparation ratio are powerfully guaranteed, and the product quality is further improved.

A system for treaty-governed genomic compilation and secure biological synthesis that regulates the translation of digital genetic information into physical matter. The apparatus comprises a Symbolic Verification Kernel configured to deconstruct target nucleic acid sequences into functional semantic representations and execute predictive biological simulations to assess toxicity and dual-use risk against an immutable Treaty Ledger. Physical synthesis is controlled by a hardware-locked DNA synthesis apparatus that remains mechanically disabled until it receives and validates a cryptographically signed Sovereign Synthesis Token issued by the kernel. The system further includes a Bio-Encryption Engine that interleaves non-coding watermarks into the synthesized material, establishing a permanent, molecular-level chain of custody for all fabricated genetic content. The architecture thereby enforces international biological safety constraints directly at the point of manufacture, preventing the unauthorized synthesis of pathogenic or restricted biological agents.

The application discloses a gene modified non-toxic toxoid vaccine based on light chain-transmembrane region L-HN and receptor binding region Hc, and a preparation method and application thereof. The gene modified non-toxic novel toxoid vaccine molecule has two important protective antigen functional domains of a biological toxin, the N terminal of the vaccine molecule is the light chain-transmembrane region L-HN, and the C terminal is the receptor binding region Hc. The two protective antigen functional domains can be derived from the same biological toxin, can produce stronger protection than a single antigen, can produce strong complete protection at a low dose and a small number of immunization times, and can be used as a high-efficiency gene engineering toxoid vaccine to replace formaldehyde inactivated toxoid for biological toxin prevention. The two protective antigen functional domains can also be derived from different biological toxins, can protect against attacks of respective biological toxins, can produce protection against multiple different toxin biological agents, and can be used as a broad-spectrum multivalent vaccine for biological toxin prevention.
