To Be an Enlightened Superpower
That the United States will continue to play a leading role in the world is a given. The question is not whether but how it should play this role. Here is a Chinese perspective on how the United States can act as an enlightened superpower.
From wheels to webs: Reconstructing Asia‐pacific security arrangements
The commander‐in‐chief of U.S. Pacific Command (CINCPAC) outlines the new U.S. regional security strategy. The United States is building on the hub‐and‐spoke arrangement of bilateral alliances to form “security communities” of states with shared interests.
Effect of antioxidants, on deterioration by partial discharge in LDPE and XLPE [insulation materials]
The effect of antioxidants in low-density polyethylene (LDPE) and cross-linked polyethylene (XLPE) on deterioration by partial discharge (PD) was investigated. Experiments were conducted using LDPE and XLPE samples containing phenolic antioxidants. Samples subjected to the PD were analyzed using atomic force microscopy and Fourier transform infrared analysis (AFM and FTIR). AFM images demonstrated that the magnitude of pits created in the sample containing antioxidants was smaller than that in samples containing no antioxidant. FTIR showed that oxidative degradation occurred on LDPE and XLPE surfaces when they were subjected to PD. These results confirmed that the amount of oxidized substances was smaller in samples containing phenolic antioxidants than in those containing no antioxidant. This report elucidates the mechanism of antioxidant action on deterioration by PD.
