A Real-Time Surveillance System for Vaccine Cold Chain Based o n Internet of Things Technology
Shao-jun Jiang,Zhi-lai Zhang,Wen-yan Song 한국정보처리학회 2023 Journal of information processing systems Vol.19 No.3
In this study, a real-time surveillance system using Internet of Things technology is proposed for vaccine coldchains. This system fully visualizes vaccine transport and storage. It comprises a 4G gateway module, lowpowerand low-cost wireless temperature and humidity collection module (WTHCM), cloud service softwareplatform, and phone app. The WTHCM is installed in freezers or truck-mounted cold chain cabinets to collectthe temperature and humidity information of the vaccine storage environment. It then transmits the collecteddata to a gateway module in the radiofrequency_physical layer (RF_PHY). The RF_PHY is an interface forcalling the bottom 2.4-GHz transceiver, which can realize a more flexible communication mode. The gatewaymodule can simultaneously receive data from multiple acquisition terminals, process the received datadepending on the protocol, and transmit the collated data to the cloud server platform via 4G or Wi-Fi. Thecloud server platform primarily provides data storage, chart views, short-message warnings, and otherfunctions. The phone app is designed to help users view and print temperature and humidity data concerningthe transportation and storage of vaccines anytime and anywhere. Thus, this system provides a new vaccinemanagement model for ensuring the safety and reliability of vaccines to a greater extent.

Biogenic Mn oxides are expected to have great potential in the control of water pollution due to their high catalytic activity, although information on biological Mn oxidation is not currently sufficient. In this study, the growth of a Mn oxidizing microorganism, Pseudomonas putida MnB1, was examined, with the Mn oxides formed by this strain characterized. The growth of P. putida MnB1 was not significantly influenced by Mn(II), but showed a slightly decreased growth rate in the presence of Pb(II) and Ee₂, indicating their insignificant adsorption onto the cell surface. Mn oxides were formed by P. putida MnB1, but the liquid growth medium and resulting biogenic solids were poorly crystalline, nano-sized particles. Biogenic Mn oxidation by P. putida MnB1 followed Michaelis-Menten kinetics, with stoichiometric amounts of Mn oxides formed, which corresponded with the initial Mn(II) concentration. However, the formation of Mn oxides was inhibited at high initial Mn(II) concentration, suggesting mass transfer obstruction of Mn(II) due to the accumulation of Mn oxides on the extracellular layer. Mn oxidation by P. putida MnB1 was very sensitive to pH and temperature, showing sharp decreases in the Mn oxidation rates outside of the optimum ranges, i.e. pH 7.43-8.22 and around 20-26℃.

Gloeostereum incarnatum is an edible medicinal mushroom widely grown in China. Using the whole genome of G. incarnatum, simple sequence repeat (SSR) markers were developed and synthetic primers were designed to construct its first genetic linkage map. The 1,048.6 cm map is composed of 10 linkage groups and contains 183 SSR markers. In total, 112 genome assembly sequences were anchored, representing 16.43 Mb and covering 46.41% of the genome. Selfing populations were used for quantitative trait loci (QTL) targeting, and the composite interval mapping method was used to co-localize the mycelium growth rate (potato dextrose agar and sawdust), growth period, yield and fruiting body length, and width and thickness. The 14 QTLs of agronomic traits had LOD values of 3.20–6.51 and contribution rates of 2.22– 13.18%. No linkage relationship was found between the mycelium growth rate and the growth period, but a linkage relationship was observed among the length, width and thickness of the fruiting bodies. Using NCBI’s BLAST alignment, the genomic sequences corresponding to the QTL regions were compared, and a TPR-like protein candidate gene was selected. Using whole-genome data, 138 candidate genes were found in four sequence fragments of two SSR markers located in the same scaffold. The genetic map and QTLs established in this study will aid in developing selective markers for agronomic traits and identifying corresponding genes, thereby providing a scientific basis for the further gene mapping of quantitative traits and the marker-assisted selection of functional genes in G. incarnatum breeding programs.

Shao Hao,Jiang Shuguang,Wu Zhengyan,Zhang Weiqing,Wang Kai 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.12
The belt fire in coal mine has the characteristics of fast burning velocity, not easily extinguishing a fire and generating a great deal of poisonous and toxic gas. Once the belt fire happens, it will result in a large number of casualties and enormous property loss, which is one of the greatest disasters that influence on the safety production in coal mine. To reduce the number of casualties and property loss caused by belt fire, the long-distance emergency rescue system for belt fire is proposed, and used to directly import the poisonous and toxic gas produced by belt lane into return airway in order to guarantee the safety of staffs working in mining area. In order to research on how the efficiency of using the system and what the system has additional impact on the ventilation system, the present study applies the approach of numerical stimulation to establish the two-dimensional model of ventilation system. After the belt fire happens, and then this paper researches on the flow laws of poisonous and toxic gas, and explores the long-distance emergency rescue system for belt fire influencing on the ventilation system and controlling the poisonous and toxic gas. The current study yields the conclusions as follows: (1) how poisonous and toxic gas produced by belt fire in different ventilation models spreads and moves in the roadway; and (2) how the long-distance emergency rescue system for belt fire influences on the ventilation system. This research has certain instructive significance and reference value for improving the level of emergency rescue about the belt fire, and reducing the number of casualties and property loss caused by belt fire.

Objective: To investigate uPA and VEGF expression in esophageal cancer and relations with tumorous invasion and metastasis. Methods: Immunohistochemistry was used to detect uPA and VEGF expression in the normal epithelial tissue of esophageal mucosa and cancer tissue and detect CD34 labeled micrangium and analyze the relationships with clinical pathological features and tumor angiogenesis. Results: Positive rates for uPA and VEGF protein expression were significantly greater in esophageal cancer than normal epithelial tissue (P < 0.05), the two being linked (P <0.05). In addition, uPA and VEGF protein expression of the high microvessel density (MVD) group was significantly lower than in the low MVD group (P < 0.05), with relation to clinical pathological staging, differentiation and lymph node metastasis (P < 0.05). Conclusion: In esophageal cancer tissue, uPA and VEGF proteins are overexpressed and promote tumor angiogenesis, indicative of a poor prognosis.

Brazilian splitting tests, uniaxial compression tests and triaxial compression tests are carried out on the coal samples cored from Shanxi group $II_1$ coal seam of Jiaozuo coal mine, Henan province, China, to obtain their property parameters. Considering the bedding has notable effect on the property parameter of coal, the samples with different bedding angles are prepared. The effects of bedding on the anisotropic characteristics of the coal seam are investigated. A geological geomechanical model is built based on the geology characteristics of the Jiaozuo coal mine target reservoir to study the effects of bedding on the fracture propagations during hydraulic fracturing. The effects of injection pressure, well completion method, in-situ stress difference coefficient, and fracturing fluid displacement on the fracture propagations are investigated. Results show bedding has notable effects on the property parameters of coal, which is the key factor affecting the anisotropy of coal. The hydraulic cracks trends to bifurcate and swerve at the bedding due to its low strength. Induced fractures are produced easily at the locations around the bedding. The bedding is beneficial to form a complicated fracture network. Experimental and numerical simulations can help to understand the effects of bedding on hydraulic fracturing in coalbed methane reservoirs.
