Three difficult months in ‘Iraq

Though the build-up of China's blue-water fleet is causing consternation in foreign-policy circles, the country's on-going expansion into Russia and the former Soviet Union has scarcely garnered comment. For the past decade, China has used its foreign reserves to acquire strategic assets (principally infrastructure and natural resources) and tracts of sovereign territory along its existing borders and increasingly further afield. The impact on targeted countries (and, in turn, their own foreign policy) is extreme, with serious implications for security and economics far beyond their borders. This article provides an overview of China's acquisitions and investments in Eurasia, followed by more detailed discussion of recent developments and responses in Central Asia, Ukraine and Mongolia, and Siberia. It then looks at the impact of China's actions on Sino-Russian relations, discusses the importance of Russia and Central Asia as a resource corridor and buffer zone between Europe and China, and suggests how these manoeuvrings might result in long-term benefits for China.     

A methodology based on NMR spectroscopy for the forensic analysis of condoms.

Both solution and solid state Nuclear Magnetic Resonance (NMR) spectroscopic techniques have been used to determine differences in commercially available condoms. Whilst solid state NMR is useful for determining the polymer backbone, it is not useful for forensic analysis due to the commonality of the latex condom. However solution NMR spectra obtained following a simple extraction procedure using hexane, provides a fingerprint of the additives in the lubricants. Following the development of a flow chart, basing decisions on the presence of particular peaks present in the solution spectra, 33 of 38 condoms could be individualized. Samples were also analyzed after having the lubricant manually removed and soaking the condom in water for 3 to 24 h. These experiments were performed to simulate a case of the sample having been used and disposed of by flushing down the toilet, as may be experienced in a case of a sexual assault. The results indicated that the only significant water soluble component was polyethylene glycol. The overall results suggest that the method developed may be a quick and useful technique in characterizing condoms. The information obtained can be used to provide associative evidence between suspect and crime, and so be useful in sexual assault cases.
