A crucial deformation phenomenon is observed in shale and silty clay sections in a tunnel. To analyse the reinforcement and support mechanism and behaviour of the tunnel support structure in layered soft rocks, field tests for the axial force of the cartridge rock bolt, surrounding rock pressure, stress of a steel I-beam and lattice girder were performed. Based on the field deformation analysis data, the reinforcement behaviours of the cartridge rock bolt and steel floral pipe, and support behaviours of lattice girder and steel I-beam in the layered rock mass and silty clay were analysed.

Transition-metal-embedded carbon nanotubes (CNTs) have been accepted as a novel type of sensing material due to the combined advantage of the transition metal, which possesses good catalytic behavior for gas interaction, and CNTs, with large effective surface areas that present good adsorption ability towards gas molecules. In this work, we simulate the adsorption of O2 and O3 onto Rh-doped CNT in an effort to understand the adsorbing behavior of such a surface. Results indicate that the proposed material presents good adsorbing ability and capacities for these two gases, especially O3 molecules, as a result of the relatively large conductivity changes. The frontier molecular orbital theory reveals that the conductivity of Rh-CNT would undergo a decrease after the adsorption of two such oxidizing gases due to the lower electron activity and density of this media. Our calculations are meaningful as they can supply experimentalists with potential sensing material prospects with which to exploit chemical sensors.

Magnetically-coupled resonant wireless power transfer (MCR-WPT) system with LCL-S structure is developing for higher transmission characteristics. This paper improves the resonance topology structure by adding a compensation capacitor in the transmitting side and proposes a parameter confi guration method with equivalent impedance. The transmission characteristics are analyzed fi rst based on simulation method to determine the parameters for the system requirements of 3 kW output power at working frequency of 85 kHz. Then the improved MCR-WPT system is developed. The realization methods of key modules such as electromagnetic coupling mechanism and drive circuit are given. The experiments are designed and are used to analyze the eff ect of diff erent frequency and diff erent distance on transmission characteristics. Output power and transmission effi ciency of the designed system can be 3141 W and 91% respectively. In addition, the inverter’s performance and the system electromagnetic radiation state are evaluated. The results show that the designed system can provide an eff ective means for 3 kW WPT application at 85 kHz.

Objective: MicroRNAs are a class of endogenous small regulatory RNAs that regulate cell proliferation, differentiation and apoptosis. Recent studies on miRNAs are mainly focused on mice, human and pig. However, the studies on miRNAs in skeletal muscle of sheep are not comprehensive. Methods: RNA-seq technology was used to perform genomic analysis of miRNAs in prenatal and postnatal skeletal muscle of sheep. Targeted genes were predicted using miRanda software and miRNA-mRNA interactions were verified by quantitative real-time polymerase chain reaction. To further investigate the function of miRNAs, candidate targeted genes were enriched for analysis using gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment. Results: The results showed total of 1,086 known miRNAs and 40 new candidate miRNAs were detected in prenatal and postnatal skeletal muscle of sheep. In addition, 345 miRNAs (151 up-regulated, 94 down-regulated) were differentially expressed. Moreover, miRanda software was performed to predict targeted genes of miRNAs, resulting in a total of 2,833 predicted targets, especially miR-381 which targeted multiple muscle-related mRNAs. Furthermore, GO and KEGG pathway analysis confirmed that targeted genes of miRNAs were involved in development of skeletal muscles. Conclusion: This study supplements the miRNA database of sheep, which provides valuable information for further study of the biological function of miRNAs in sheep skeletal muscle.
