Confirmation of material properties is an important research area for determining metals deformation behavior. In order to research the effect of flow stress calculation on aluminum alloy sheet deformation behavior,warm sheet bulging test was carried out to obtain bulging height - pressure curves with different bulging heightsand diameters in this study. Based on the bulging parts profile data measured by three coordinate measuringmachine, the least square circle fitting radius were fitted. Existing theoretical models for radius of curvatureand thickness were compared and best models were selected to obtain more accurate stress - strain curves bycalculating the bulging flow stress. Combination model was used to calculate the bulging height - pressurecurves obtained by bulging test and the stress-strain curves with different temperatures and pressure rates wereobtained. A monotonous increasing function was resulted which is of great significance in the area of formabilityand deformation behavior of warm sheet hydroforming.

Sun Chang,Sun Kangning,Pang Laixue,Liu Jian 한국자기학회 2016 Journal of Magnetics Vol.21 No.1
In this study, we report the as-prepared MgO-doped BaFe12O19, which was prepared by calcination technique and high-energy ball milling process, as an electromagnetic wave absorber. The phase analysis of BaFe12O19 and the as-prepared MgO-doped BaFe12O19 was detected utilizing X-ray Diffractometer (XRD). The microstructure was characterized using Scanning Electron Microscope (SEM). By means of the transmission/reflection coaxial line method, the electromagnetic properties and microwave absorbing properties of the asprepared electromagnetic wave absorber were studied. It is found that the electromagnetic wave absorber has a minimum reflection loss value of –41 ㏈ at 4.27 ㎓ with a matching thickness of 2.6 ㎜. The experiment results revealed that the as-prepared electromagnetic wave absorber could find potential applications in many military as well as commercial industries.

Glucagon-like peptide-2 (GLP-2) is important for intestinal barrier function and regulation of tight junction (TJ) proteins, but the intracellular mechanisms of action remain undefined. The purpose of this research was to determine the protective effect of GLP-2 mediated TJ and transepithelial electrical resistance (TER) in lipopolysaccharide (LPS) stressed IPEC-J2 cells and to test the hypothesis that GLP-2 regulate TJ and TER through the phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt)-mammalian target of rapamycin (mTOR) signaling pathway in IPEC-J2 cells. Wortmannin and LY294002 are specific inhibitors of PI3K. The results showed that $100{\mu}g/mL$ LPS stress decreased TER and TJ proteins occludin, claudin-1 and zonula occludens protein 1 (ZO-1) mRNA, proteins expressions (p<0.01) respectively. GLP-2 (100 nmol/L) promote TER and TJ proteins occludin, claudin-1, and zo-1 mRNA, proteins expressions in LPS stressed and normal IPEC-J2 cells (p<0.01) respectively. In normal cells, both wortmannin and LY294002, PI3K inhibitors, prevented the mRNA and protein expressions of Akt and mTOR increase induced by GLP-2 (p<0.01) following with the significant decreasing of occludin, claudin-1, ZO-1 mRNA and proteins expressions and TER (p<0.01). In conclusion, these results indicated that GLP-2 can promote TJ's expression and TER in LPS stressed and normal IPEC-J2 cells and GLP-2 could regulate TJ and TER through the PI3K/Akt/mTOR pathway.

Epoxy-coated rebar is a crucial material in marine construction. To study the bond performance of epoxy-coated rebar withhigh-strength concrete in different structural forms, pull-out tests were conducted on 18 specimens. The failure patterns andbond-slip behavior of different epoxy-coated rebar-high strength concrete specimens were analyzed. Based on these tests,finite element analysis software Abaqus was used to conduct a parametric analysis by varying the rebar diameter and bondlength, investigating the ultimate bond strength of components under different parameters. The results indicate that due tothe relatively low compressive strength of the concrete, specimens exhibited rebar pull-out failure, concrete splitting failure,and rebar fracture failure during the pull-out tests. As the rebar diameter increased, the anchoring capacity of the epoxycoatedrebar improved. Specifically, for every 1 mm increase in diameter, the ultimate bond load increased by 16.9% to23.9%. Additionally, increasing the bond length of the rebar enhanced the ultimate bond strength of the specimens, with theultimate bond load increasing by 13.2% to 24.2% for every 1d increase in length. The conclusions drawn from this researchprovide technical support for the engineering application of epoxy-coated rebar in high-strength concrete.
