Published: June 2020

Abstract
In order to investigate the effects of the M229 and M307 locus in FUT1 gene on the carcass and meat quality of Congjiang pigs. In this study, PCR-SSCP, PCR-RFLP and direct sequencing methods were used to quickly type the M229 and M307 loci, and then the association between different genotypes and meat traits was analysed. Population genetic structure analysis showed that M229 locus of FUT1 gene was in Hardy-Weinberg equilibrium, with high polymorphism information content, rich genetic diversity and large space for directional breeding. However, the M307 locus had the opposite result, showing a skewed distribution. Correlation analysis showed that the average backfat thickness index of CT and TT genotypes from the M229 locus of FUT1 gene in Congjiang pigs was significantly lower than that of CC (P <0.05). The conclusion of this experiment indicates that the M229 locus of FUT1 gene can be strengthened in Congjiang pigs, which can be used for breeding applications.

Authors: Feng Xuesong , Zhang Xiaokun , Xiang Yong 
Published: June 2020

Abstract
As the residual value of the lead-acid batteries is not effectively evaluated in the current scraping and recycling processes of the lead-acid batteries, the partition around medoids (PAM) clustering algorithm is adopted, and the scraped lead-acid batteries are classified with the changes in the temperature and charge-discharge occurring when the lead-acid batteries are in service as the characteristic parameters. Besides, the validity of the algorithm is validated using 300 lead-acid battery packs to be scrapped at the communication base station, from which the results showed that the residual value of the lead-acid batteries can be effectively distinguished by the partition around medoids algorithm according to the temperature and charge-discharge characteristic parameters.

Abstract
Amydrium sinense has been widely used to treat rheumatism are in ethnic areas. The modern studies have shown that rheumatism is closely related to inflammation, and volatile oil of traditional Chinese medicine has anti-inflammatory activity, but the mechanism is not fully elucidated. In this study, the potential mechanism of anti-inflammatory effect of Amydrium sinense was systematically explored by using the network pharmacology. Firstly, the active chemical ingredients of Amydrium sinense were prescreened according to ADME parameters (OB≥30% and DL≥0.18) and the Pharmacological activity. The potential targets were screened with the databases of TCMSP. Then the “component-target-disease” network was constructed using Cytoscape 3.6.1 software. Finally, GO (gene function) enrichment analysis were carried out by biological information annotation database (DAVID), and signal pathway analysis were executed by KEGG Pathway database. The network analysis revealed that 27 compounds were screened as active compounds; 193 targets were searched, of which 38 potential targets the most were closely related to the prevention and treatment of inflammation. In addition, it suggested that 212 biological processes and 79 signalling pathways were screened. Among them, the signalling pathway most closely related to the relevant regulated of NF-kB, TNF, Toll-like receptor signalling pathway, Hepatitis B and Inflammatory response, etc. Its anti-inflammatory mechanism may coordinate with each other through multiple processes to exert anti-inflammatory biological effects. The above results provide strong support for studying the molecular mechanism of Amydrium sinense in the treatment of inflammation.

Abstract
Magnetic nanoparticles (MNPs) are playing an increasingly important role in the biomedical fields such as the diagnosis, treatment and monitoring of various diseases. Due to the unique properties of MNPs, MNPs with functionalized non-toxic surface coatings can be used for drug delivery in combination with therapeutic drugs or chemical molecules. A novel type of drug-attached magnetic nanoparticle was presented, where insulin was bound to magnetic Fe3O4 nanoparticles (MNPs-Insulin). It was particularly proposed for the future in vivo control to realize the targeted locomotion. The properties of the MNPs-Insulin were characterized by Fourier-transform infrared spectra (FTIR), thermo gravimetric analysis (TGA) and vibrating sample magnetometer (VSM) analysis. The ability of magnetic control was tested in the local motion control system in vitro. The good biocompatibility was certificated by Hematoxylin-eosin staining (HE) on mouse.

Abstract
To explore the protective effects of Ya ’an Tibetan Tea on 60Coγ irradiation damage in mice, forty-eight male SPF mice were randomly divided into six groups, including normal control group, irradiation control group, positive control group and Ya’an Tibetan tea low, medium and high-dose groups. Each group of mice were administrated with corresponding test samples for continuously 15 days. All mice were irradiated by 60Coγ-rays at the dose of 5 Gy except normal control group on the 6th day. After gavage, the mice were dissected and blood was taken from the eyeballs. The total antioxidant indexes of liver tissues, peripheral blood cells, and bone marrow DNA content of the mice were measured. The results showed that compared with the radiation control group, the contents of peripheral blood cells in the three dose groups of Ya’an Tibetan Tea increased in varying degrees, with the largest increase in the medium=dose group. In the medium=dose group, WBC were significantly increased (P<0.01), and RBC were increased (P<0.05), and the content of bone marrow DNA of the medium-dose group was significantly different from the radiation control, and MDA significantly decreased (P<0.01), and T-SOD activities and T-AOC activities significantly increased (P<0.01). The study shows that Ya’an Tibetan tea has a strong protective effect on radiation-damaged mice, and the medium-dose group has the best effect.

Abstract
With the increasing number of terror attacks in France, evacuation plans at the Louvre, which receives tens of thousands of visitors every year, has become the key to the safety of visitors. Our goal is to make a reasonable emergency evacuation plan. First, we establish a two-dimensional evacuation model, based on the model, we build a three-dimensional cellular automaton model, which takes the speed of moving up and down the stairs of the occupants, positional attraction and probability of collisions into consideration. Second, we use Pathfinder for simulation. Finally, we find that the exit 1(secondary entrance) should be opened when the visitor density is high, while the exit 3 should be opened when the visitor density is low; and the Passage Richelieu entrance has the greatest influence on evacuation time, and emergency personnel should choose the Pyramid entrance as their emergency entrance.

Abstract
In order to change the current situation that the mooring chain magnetic particle detection is completely completed manually by workers, and improve the detection coverage accuracy, an automatic mooring chain full-ring magnetic particle detection device has been developed to fill the domestic gap. The device is mainly composed of 4 parts: a vertical scanning mechanism, a circular rotation mechanism, a probe linear motion mechanism and a probe adaptive mechanism, which have a total of 6 degrees of freedom. At the same time, ABAQUS finite element analysis software was used to check the static strength, stiffness and dynamic characteristics of the large-span vertical scanning mechanism in the device. The calculation results show that the static strength and stiffness of the vertical scanning mechanism are reliable; the driving pulsation frequency is far from the main excitation frequency, and the structure has good dynamic characteristics.

Authors: Feng Wenqi , Li Yang , Yuan Qijie , Xie Zhongzhi , Ding Geyuan , Ji Chenyu 
Published: June 2020

Abstract
The force caused by the difference of thermal expansion coefficient between concrete aggregates at ultra-low temperature will inevitably affect the structure and should be considered in the structural design. The coefficient of thermal expansion of cement mortar and stone was measured by resistance strain gage test technology in ultra-low temperature environment, and the variation law of average linear expansion coefficient with temperature was obtained. The results show that the thermal expansion coefficients of cement mortar and stone have similar variation rules with the change of temperature. The stress state of cement mortar and stone under ultra-low temperature does not affect their thermal expansion coefficient. Thermal expansion coefficient of cement mortar under ultra-low temperature is affected by size effect.
