‘Ali Baba's Cave’: The Sea of Okhotsk's Contentious Triangle

Amidst international furor over its annexation of Crimea, Russia quietly acquired a far more lucrative territory through different means: in March, the United Nations recognized Russia's claim to the resource-rich “Peanut Hole” in the center of the Sea of Okhotsk. This strategically and economically important body of water—a “real Ali Baba's cave” of untapped oil and gas reserves—lies within a contentious triangle formed by eastern Russia and northern Japan. Securing the Okhotsk's legal status as an internal sea goes far to advancing Russian claims in the Arctic, and bolsters Russia's bargaining position over four disputed Kuril islands which Japan callsits “Northern Territories.”     

X‐ray Scattering Evaluation of Ultrastructural Changes in Human Dental Tissues with Thermal Treatment

Micro‐ and ultrastructural analysis of burned skeletal remains is crucial for obtaining a reliable estimation of cremation temperature. Earlier studies mainly focused on heat‐induced changes in bone tissue, while this study extends this research to human dental tissues using a novel quantitative analytical approach. Twelve tooth sections were burned at 400–900°C (30‐min exposure, increments of 100°C). Subsequent combined small‐ and wide‐angle X‐ray scattering (SAXS/WAXS) experiments were performed at the Diamond Light Source synchrotron facility, where 28 scattering patterns were collected within each tooth section. In comparison with the control sample, an increase in mean crystal thickness was found in burned dentine (2.8‐fold) and enamel (1.4‐fold), however at a smaller rate than reported earlier for bone tissue (5–10.7‐fold). The results provide a structural reference for traditional X‐ray scattering methods and emphasize the need to investigate bone and dental tissues separately to obtain a reliable estimation of cremation temperature.     

Cyclic Pentanone Peroxide: Sensitiveness and Suitability as a Model for Triacetone Triperoxide

Research to counter the threat of organic peroxides such as triacetone triperoxide (TATP) is at times hampered by their inherent extreme sensitiveness and volatility. This work describes an approach to lowering some risks associated with the handling of TATP in the laboratory through the use of an analog species, tripentanone triperoxide (TPTP). Sensitiveness has been tested via standard methods. GCMS analysis has shown that TPTP degrades via similar mechanisms to TATP under a range of conditions. Slight differences in product composition were traced to side reactions which may also affect impurities present in homemade TATP synthesis. A pilot field trial was conducted to evaluate TPTP as a substitute for TATP in explosive detection dog (EDD) scent training. The degradation studies have yielded insights into the complexities of the acidic degradation of cyclic peroxides with potential forensic application, and TPTP's inadequacy as a TATP pseudoscent is a valuable example of the limitations of such training aids.     

The Third Way Project in Britain: The Role of the Prime Minister's Policy Unit

The reputedly pragmatic Prime Minister's Policy Unit focuses on 'what works', but has also sought to elaborate the governing philosophy of the 'third way'. By explaining what the government is doing and why, the third way is meant to improve electoral performance and policy co-ordination, enhance democracy and unite the party. This article identifies conflicts within and between these goals. It concludes that electoral concerns and party unity have been paramount for the Policy Unit.
